As we all know, the producer gas furnaces used in the glass industry all adopt the combustion mode of periodic commutation. The biggest disadvantage of this method is that there is a lot of gas in the gas channel and regenerator at the back end of the gas commutator, which is discharged into the atmosphere through the chimney after commutation, which not only wastes energy but also pollutes the environment. The "gas recovery device" we developed fundamentally solved this difficult problem, and all the previously discharged gases were recovered. The device has been put into use in Longkou Sheng Da Glass Products Co., Ltd., and the effect is good. If you are interested, we are willing to provide you with services and help.
1. Safety: The gas recovery process is completely controlled, and each recovery unit works according to the procedures.
The action is reasonable and accurate. Each unit has reliable safety protection function. When there is a power failure or unit abnormality, the system will automatically reset and warn the fault location. Due to comprehensive consideration and excellent manufacturing, the recycling process is absolutely safe and reliable.
2. Energy saving: according to the calculation of changing direction every 30 minutes, it can save about 3% of coal and achieve energy saving effect.
Obviously. After the device is put into use in the 60M2 kiln of Longkou Sheng Da Glass Products Co., Ltd., 600kg of high-quality lump coal can be saved every day, and the economic benefit is objective.
3. Environmental protection: completely eradicate the problem of yellow smoke from chimneys, reduce pollutant emissions and protect the environment.
Glass production enterprises are large energy consumers, and energy conservation and emission reduction has always been the focus of the government's energy conservation and environmental protection departments.
The urgent task is to create a situation.
Four. Project implementation steps:
1. Preparation of relevant technical data: cross-sectional dimensions of flue, flue gas emission, gas commutator and flue gas shall be provided.
Road and surrounding civil plan, etc. , so as to select recycling devices with matching specifications and reasonable layout.
2. Process diagram design: According to the flue direction and equipment direction of the kiln, draw the process diagram of the recovery device. When necessary
Need to go to the scene to confirm.
3. Equipment manufacturing cycle: The equipment manufacturing process generally takes one and a half months.
4. Installation and commissioning period: The equipment installation will be carried out during the newly-built kiln or the overhaul of the kiln for one week.
5. Normal service life: The device can be used after the kiln is officially unloaded and operated. It moves synchronously with the gas commutator.
No special personnel are needed to operate, and the recovery process is automatically completed by program control.
5. Investment benefit estimation: accounting for 60 square meters kiln of Longkou Sheng Da Glass Products Co., Ltd. ..
1. The total investment of the project is 65438+500,000 yuan. The price is related to the material selection, manufacturing quality, reliability and service life of supporting facilities. People often say that you get what you pay for.
2. It can save 600kg of high-quality lump coal every day, with Longkou coal price 1 100 yuan/ton, and save 660 yuan every day.
It can save 660x365=240900 yuan every year.
3. The electricity fee is 0.05 yuan each time, and the electricity fee in 2.4 yuan is 876 yuan per year.
4. The design life of the equipment can reach more than 15 years, and the annual depreciation expense is about10 million yuan.
5. Economic benefit accounting: the actual annual benefit is 240900-876- 10000≈24 (ten thousand yuan).
6. Payback period of investment: (6,543.8+0.5 million yuan/240,000 yuan) x 654.38+0.2 (month) =7.5 (month).
