Abstract
The invention discloses a still kettle tail gas recovery system. The still kettle tail gas recovery system comprises multiple cylinders and multiple still kettles. Each one of the still kettles comprises a kettle body, the kettle body is provided with an air inlet and an exhaust port, and the top of the kettle body is provided with a kettle cover. Each one of the cylinders comprises a first main cylinder, a second main cylinder, a first recovery cylinder and a second recovery cylinder. Through reasonable arrangement of the multiple cylinders and the multiple still kettles, high pressure gas in the still kettles is subjected to stepwise reverse gas recovery and generally, gas pressure can be decreased to below 0.2MPa and thus when the still kettles are opened, gas lost is greatly reduced, pollution is greatly reduced and pressed gas in the cylinders can be returned to the still kettles so that follow-up processes are convenient. The still kettle tail gas recovery system can save fire coal based on a ratio of about 300kg of fire coal per still kettle. Based on 100000 cubic meters of concrete building blocks produced in each year, the fuel acquisition expense of more than 600000 yuan can be saved in each year so that an enterprise production cost is greatly reduced and product competitiveness in the market is improved.
Description
Technical field
The present invention relates to a kind of device for recovering tail gas, especially relate to a kind of still kettle exhaust gas recovery system.
Background technology
Autoclave aerated concrete building block is to add aluminium powder to make air-entrainment in the batching with calcareous material (cement, lime etc.) and siliceous material (sand, coal dust ash, slag etc.), through adding water stirring, moulding by casting, the expansion of getting angry, the cutting of resting, then the porous silicate building block forming through autoclave curing.The weight of autoclave aerated concrete building block is 1/3rd of equal volume clay brick, its heat-insulating property is 3-4 times of clay brick, sound insulation value is 2 times of clay brick, anti-permeability performance is the more than a times of clay brick, fire resistance is 6-8 times of armored concrete, its workability is good, can as timber, process.In building packing material application aspect, the application of autoclave aerated concrete building block is more and more extensive.
Still kettle is after completing building block steam pressure, and still internal gas pressure generally remains on 1.0Mpa left and right, and still inner vapor is to produce by coal-fired, burning 100KG coal, and still internal gas pressure promotes and is less than 0.1Mpa.In order to save the energy, many enterprises are all used union between still kettle, to fall gas, and part HCS is switched in other empty still kettles, and two still kettles fall gas and reach after balance, and two still kettle internal gas pressures are 0.5Mpa left and right.In order again to carry out steam pressure operation, one of them still kettle needs emptying, have the steam of half to waste, and gas reactor excitant is very strong, and CO2 content is large, and emptying noise is also very large; Fire coal is increased to 1.0Mpa by still internal pressure again again, needs extra nearly half ton of coal that consume, by 800 yuan of calculating of 1 ton of coal, 400 yuan of every still wastes, a factory that produces 10 ten thousand stere autoclave aerated concrete building blocks per year, calculates by producing 3000 stills, and the waste on fire coal is just up to 1,200,000.
