Question 2:6s definition of cleanliness generally refers to standardization and long-term. However, I suggest that you understand and remove cleaning as: finding and removing six sources 1, pollution source 2, dead angle source 3, fault source 4, waste source 5, hazard source 6 and defect source, so as to maximize the role of cleaning in 5S.
Question 3: What does cleaning mean? Sweep the rubbish and dust with a broom and brush.
Clean the room and make it clean.
Question 4: Overview of the definition of wet cleaning
Wet dust removal is a method of purifying gas, and the dust particles are washed down by the full contact between washing liquid (usually water) and dusty gas. This dust removal method has the advantages of high efficiency, simple structure, low cost, small floor space, convenient operation and maintenance, etc., and is especially suitable for treating high temperature, high humidity, flammable and explosive dusty gases. In addition, some gas pollutants can be removed at the same time of dust removal. Therefore, it is widely used in air pollution control and gas purification in various departments of industrial production.
It is necessary to treat the washed dusty sewage and sludge; When treating and purifying corrosive gas pollutants, the washing water is corrosive to some extent, and the equipment is easy to be corroded. Therefore, anti-corrosion measures should be taken, which is higher than the operating cost of ordinary dry dust collector.
Wet desulfurization dust collector is widely used in metallurgy, mining, power generation, heating and other industries, and has high dust removal and desulfurization effect on power station boilers, industrial boilers, heating boilers and industrial kilns. The emission concentration meets the requirements of the national environmental protection standard "Emission Standard of Air Pollutants for Boilers" GB13271-2001.
Wet dust removal technology
Wet dust removal technology absorbs the air attached to dust particles through pressure drop, and removes dust under the dual effects of centrifugal force and mixing of water and dust gas, which can efficiently treat dust of various materials and sizes, including micron-sized fine particles. The unique impeller design can produce higher pressure drop and airflow speed, thus providing higher dust removal efficiency. The design of the exhaust fan has also been fully estimated to ensure that it can meet the needs of system upgrade and higher pressure drop. Baimeidikang wet dust removal technology supporting equipment can provide three sludge output modes: manual cleaning, automatic dredging and continuous sewage discharge. The uniquely designed baffle can remove water droplets remaining in the air, and the dust removal efficiency can be flexibly adjusted by changing the height of the baffle. In the process of use, the minimum pressure drop and suitable power can be determined according to the particle size of dust, so as to realize the best combination of high efficiency dust removal and low cost.
principle of operation
When the induced draft fan is started, the air in the dust collector is quickly exhausted, and at the same time, the dust-containing gas enters the dust collector along the flue under the action of atmospheric pressure, and is fully mixed with the washing water mist sprayed by the reflective spraying device, so that the fine dust particles in the flue gas are condensed to form coarse polymers. Under the action of the guide, the airflow rushes into the washing liquid in the barrel at a high speed, generating a large amount of foam on the liquid surface and forming a water film, so that the dust-containing flue gas and the washing liquid have sufficient time to interact and capture the dust particles in the flue gas. Sulfur dioxide in flue gas has strong hydrophilicity and can be absorbed by alkaline solution to achieve the effect of dust removal and desulfurization. The purified flue gas passes through a three-stage gas-liquid separation device to remove water mist and is discharged into the atmosphere through a chimney. Sewage can be discharged into boiler slag remover or circulating pool, which can be recycled after precipitation and neutralization, and sludge can be discharged from slag remover or removed by other devices.
operating characteristic
Simple structure, reasonable layout, convenient operation, small floor space, acid-resistant and wear-resistant cement lining technology for internal corrosion protection, strong chemical stability, good thermal stability and long service life. There is a three-stage dehydration device inside the vacuum cleaner, and the air and water are completely separated, and the fan does not take water. The dust removal and desulfurization are synchronous, there is no scaling and blocking problem, the washing water is recycled, and the operating cost is low.
Technical indicators
Dust removal efficiency: > 98%, desulfurization efficiency: > 75%, Ringelmann blackness: >
Question 5: 5S management, what does it mean to be clean inside? 5S management -SEISO.
Meaning: Sweep and clean up garbage, dust and dirt, so that the site is clean and tidy, free of garbage and dust.
Objective: To eliminate "dirt" in all parts of the work site.
Objective: To reduce work-related injuries, ensure quality and create a workplace with high operating rate.
Methods: Carry out rectification work, carry out routine cleaning and clean up dirt.
Key points: In this process, it is necessary to determine the standards, divide the scope of responsibility, determine the frequency, acceptance standards and procedures, and at the same time, try to involve as many people as possible. In principle, our own region is responsible for this. There shall be no omissions or blank areas in the responsibility area, and those found unqualified during the acceptance process shall be ordered to rectify immediately.
Question 6: What is the meaning of cleanliness and cleanliness literacy? 1) finishing.
The first step to improve the production site is to separate the needed people, things and things from the unwanted people, things and things, and then deal with the unwanted people, things and things. Its main point is to classify all kinds of articles actually placed and stagnant at the production site, and distinguish between those needed and those not needed at the site; Secondly, we must resolutely clean up unnecessary items on the site, such as used materials, redundant semi-finished products, chips, leftovers, garbage, waste products, redundant tools, scrapped equipment, workers' personal daily necessities, etc. The focus of this work is to resolutely clean up unnecessary things at the scene. The front and rear of each station or equipment in the workshop, the left and right of the passage, the up and down of the workshop, the inside and outside of the toolbox and the dead corner of the workshop should be thoroughly searched and cleaned to make the best use of everything. Resolutely doing this step is the beginning of establishing a good style of work. Some Japanese companies put forward the slogan: efficiency and safety begin with the end!
The main points of finishing activities are:
① Improve and increase the working area; (2) There is no sundries on the site, the streets are unobstructed, and the work efficiency is improved; (3) reduce collision opportunities, ensure safety and improve quality; (4) Put an end to management mistakes such as mixed loading and mixed loading; ⑤ It is beneficial to reduce inventory and save money; ③ Change work style and improve work mood.
Detailed rules for sorting are as follows:
Is it necessary to see everything? Do you have to say that?
(2) Distinguish between those that need immediate use, those that need temporary use and those that need long-term use;
(3) Even if it is a necessity, it should be appropriate; Reduce the number of necessities to a minimum;
(4) Some places are dispensable items, no matter how expensive, we must resolutely throw them away and never be soft:
⑤ Non-essential means that things that are not needed in this place may be useful in other places, not "completely useless", but should be found in the right place.
When the site space is not enough, don't consider adding more places first, but tidy up the existing site, and you will find it is still very spacious.
(2) rectification
Quantify and locate the people, things and things needed. After the completion of the previous step, scientifically and reasonably arrange and place the items that need to be left at the production site, obtain the required items as quickly as possible, and complete the operation under the most effective rules and regulations and the simplest process.
The main points of this rectification activity are:
(1) Items should be placed in a fixed place and area, so as to facilitate searching and eliminate mistakes caused by confusion; (2) Articles should be placed in a scientific and reasonable place. For example, according to the frequency of use of articles, things that are often used should be placed nearby (such as the work area), and things that are occasionally used or infrequently used should be placed far away (such as concentrated in a certain place in the workshop); (3) Visualize the placement of items, so that the quantitative loaded items can be counted in a few days, and the areas where different items are placed are distinguished with different colors and marks.
Reasonable placement of articles in the production site is conducive to improving work efficiency and product quality and ensuring production safety. This work has developed into a special field management method-fixed location management (its content will be further introduced in the third section).
The rectification rules are as follows:
(1) Reduce the search time to zero;
② Any abnormality (such as loss or damage) can be found immediately;
(3) Other personnel can also understand the requirements and practices, that is, other personnel can quickly find items and put them back;
Different people do it, and the result is the same (standardization).
(3) Cleaning
Clean the workplace, repair the equipment immediately if it is abnormal, and make it return to normal. Dust, oil, iron filings, garbage, etc. Will be produced in the production process of the production site, thus making the site dirty. Dirty scene will reduce the accuracy of equipment, cause frequent failures, affect product quality, and prevent safety accidents; Dirty scenes will affect people's working mood and make people unwilling to stay for a long time. Therefore, it is necessary to remove those dirt through cleaning activities and create a bright and comfortable working environment.
The main points of cleaning activities are:
(1) Articles for your own use, such as equipment and tools. Clean yourself, don't rely on others, and don't add special cleaners; (2) Equipment cleaning, focusing on equipment maintenance. Cleaning equipment should be combined with point inspection of equipment, that is, point inspection and repair; Cleaning equipment should be lubricated at the same time, and cleaning is also maintenance; ③ Cleaning is also for improvement. When cleaning the ground, flying debris and oil-water leakage are found. It is necessary to find out the reasons and take measures to improve them.
Detailed rules for cleaning are as follows:
(1) It's best to allocate the area that everyone should be responsible for cleaning. When allocating areas, we must draw a clear line absolutely, and we can't leave areas where no one is responsible (that is, dead ends).
(2) Employees who are unwilling to fulfill their duties seriously. Don't let him get away with it ... >>
