Description
Technical field
The utility model relates to a kind of system that is used for the environmental protection equipment technical field, specifically, is a kind of coal gas pressurization soot cleaning system.
Background technology
Existing blast furnace gas dry purifying dust-removing device all adopts high pressure nitrogen as the pulse dust cleaning source of the gas, does not have the blast furnace gas purification of nitrogen source of the gas then can't adopt the udst separation of dry method pulse jet for factory; There is the blast furnace gas purification of nitrogen source of the gas to adopt nitrogen in factory, then nitrogen sprayed in the coal gas, make the quality of coal gas descend as the pulse jetting deashing source of the gas.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art and defective, and a kind of coal gas pressurization soot cleaning system that is used to the blast furnace gas dry purification dust removal system that the deashing source of the gas is provided is provided.It can be used in no nitrogen source of the gas occasion, improve the quality of coal gas.
The utility model is achieved through the following technical solutions, and the utility model comprises: the smart filter collector of coal gas, high-effect cooling device, one-level reliever, low pressure gasholder, gas compressor, high pressure tank, second depressurized device, water-and-oil separator, cooling-water pump, automatic control system.Annexation is: the smart filter collector of coal gas is connected with high-effect cooling device, high-effect cooling device is connected with the one-level reliever, the one-level reliever is connected with low pressure gasholder, low pressure gasholder arrives gas compressor by pipe connection, gas compressor is connected to high pressure tank, high pressure tank is connected with the second depressurized device by pipeline, the second depressurized device is connected to water-and-oil separator, and cooling-water pump connects high-effect cooling device, gas compressor, automatic control system by the smart filter collector of signal wire connection coal gas, gas compressor, cooling-water pump.
Described automatic control system is a PLC computer programmable Controlling System, and the controlled chilling water pump is to high-effect cooling device and but water and the gas compressor keying of gas compressor cooling on demand; Also finish following work simultaneously: the smart filter collector pulse jetting deashing device of control coal gas is online decide differential pressure or the work of timing deashing; Detection also shows the smart filter collector intake pressure of coal gas, temperature; Detect and demonstration high-effect cooling device temperature out, when the high-effect cooling device temperature out is undesired, report to the police; Detect and show and detect second depressurized device top hole pressure, temperature, when second depressurized device top hole pressure, warning when temperature is undesired; Auto stop when showing each reference mark ultralimit value, securing system safety.When the system outlet gas pressure reaches upper limit gas compressor auto stop, be lower than the gas compressor of prescribing a time limit down and start automatically, can be energy-conservation.
Working process of the present utility model is: from purified gas house steward web temperature is that purified gas about 220 ℃ is removed the purified gas dust through the smart filter collector of coal gas; the safety of protection gas compressor; entering high-effect cooling device is cooled to the one-level reliever of flowing through about 40 ℃ with purified gas and enters low pressure gasholder; entering gas compressor again is forced into required pressure and sends into the high-pressure gas tank stores; conduct has required pressure after the second depressurized device enters the water-and-oil separator dehydration again; temperature; source of the gas with the deashing of degree of cleaning uses for the blast furnace gas dry sack-duster pulse blowing.
The beneficial effects of the utility model are: being exclusively used in factory does not have nitrogen source of the gas occasion, for the blast furnace gas dry sack cleaner provides the pulse jetting deashing source of the gas, make dry cleaning coal gas be achieved, keep higher calorific value and the quality of coal gas, make full use of the heat energy of blast furnace gas, be sent to power station generating and other occasion and utilize again.Coal gas pressurization soot cleaning system is energy-saving system.
