Abstract
The utility model provides a furnace gas emptying chimney of a calcium carbide furnace. The furnace gas emptying chimney comprises a chimney pipe body. The bottom of the chimney pipe body is communicated with an air inlet pipe and a calcium carbide furnace exhaust flue. The air inlet pipe is equipped with a pneumatic butterfly valve. The top of the chimney pipe body is fixedly provided with an ignition device. Once a calcium carbide furnace breaks down and furnace gas needs to be fully discharged, a remote PC successively links and opens the pneumatic butterfly valve and the ignition device to enable carbon monoxide in the furnace gas to be fully combusted to generate carbon dioxide that causes no harm to environments and human bodies, the carbon dioxide is then discharged to the upper air. Therefore, damage of harmful gas of carbon monoxide to environments and human bodies is minimized, and operation safety is improved.
Description
Technical field
The utility model relates to vent gas treatment technical field, is specifically related to a kind of calcium carbide burner gas blow-down stack.
Background technology
At present, during chemical industry furnace of calcium carbide is produced, underrun and furnace of calcium carbide move the furnace gas producing when undesired and process and become the problem that environmental administration pays close attention to most.Closed calcium carbide furnace has two flues, pure qi (oxygen) flue and exhaust uptake, during furnace of calcium carbide normal operation, CaO+3C=CaC2+CO, the concentration of carbon monoxide in its furnace gas (CO) is more than 90%, furnace gas enters purification dust removal system from pure qi (oxygen) flue, and the furnace gas after purification uses calcined limestone or supplies with user, reaches the target of recycling economy.If furnace of calcium carbide operation is undesired, as occur furnace of calcium carbide underrun, furnace of calcium carbide collapse greatly material, roasting electrode, process charge level, while keeping in repair cleaning system equipment, furnace pressure height etc., must open exhaust uptake, furnace gas is discharged in air.
Due in the furnace gas of furnace of calcium carbide containing more than 90% CO, CO is a kind of to blood and the very strong pollutant of nervous system toxicity, when concentration reaches a certain concentration, can cause serious heart patient's death.In addition, CO can participate in the reaction that photochemical fog forms and works the mischief.So furnace of calcium carbide move when undesired directly discharge furnace gas can severe contamination environment, and human body is caused serious injury.And current domestic calcium carbide industry can't effectively be processed the in line smoke problem of furnace of calcium carbide.
Utility model content
The utility model, in order to solve the problems of the technologies described above, provides a kind of calcium carbide burner gas blow-down stack, adopts the mode of ignition, effectively prevents that a large amount of carbon monoxide from directly entering in atmosphere, has controlled pollution, is conducive to the safety of environmental protection and production operation.
The technical solution of the utility model is: a kind of calcium carbide burner gas blow-down stack, comprise chimney body, and described chimney body bottom is communicated with furnace of calcium carbide exhaust uptake by air inlet pipe, and described air inlet pipe is provided with Pneumatic butterfly valve; The top of described chimney body is installed with igniter.
Further, in order to guarantee that this device can normally work at strong wind or sleety weather, the top of described chimney body is arranged with wind-proof cap.
Further, described igniter and wind-proof cap are to be all installed on the top outer wall of chimney body by fixture.
Further, in order to guarantee the security of operation and to facilitate controllability, described igniter and Pneumatic butterfly valve all carry out Remote by PC, when breaking down, furnace of calcium carbide needs when emptying, can long-rangely press releasing the button on remote controller, open successively Pneumatic butterfly valve and igniter, thereby strengthened the security that has guaranteed production operation service life of whole system.Wherein the Remote of igniter and Pneumatic butterfly valve is prior art, has at present a lot of ready-made products, at this, is not described in detail.
When breaking down, furnace of calcium carbide need to carry out when emptying furnace gas, Remote is opened Pneumatic butterfly valve, make the furnace gas in exhaust uptake enter chimney body, rise to its top outlet, the chain unlatching of igniter is also started working, carbon monoxide in furnace gas is fully burnt, and generate the carbon dioxide to environment and body harmless, then carry out high altitude discharge.
So the utility model has prevented that in the furnace gas of furnace of calcium carbide, a large amount of carbon monoxide directly enter in atmosphere effectively, thereby has controlled atmosphere pollution, is conducive to the security of environmental protection and production operation.Reduced the pernicious gas of generation during closed calcium carbide furnace is produced to the pollution of environment and to personal injury.
The utility model also can be used for the emptying of the fuel gas such as natural gas to be processed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is A portion enlarged drawing in Fig. 1;
In figure: 1-chimney body, 2-Pneumatic butterfly valve, 3-igniter, 4-wind-proof cap, 5-fixture, 6-air inlet pipe.
The specific embodiment
As shown in Figure 1, 2, a kind of calcium carbide burner gas blow-down stack, comprises chimney body 1, and chimney body 1 bottom is communicated with furnace of calcium carbide exhaust uptake by air inlet pipe 6, and air inlet pipe 6 is provided with Pneumatic butterfly valve 2; The top of chimney body 1 is installed with igniter 3, and in order to guarantee that this device can normally work in strong wind or sleety weather situation, the top of chimney body 1 is arranged with wind-proof cap 4.Igniter 3 is to be all installed on the top outer wall of chimney body 1 by fixture 5 with wind-proof cap 4.
Further; in order to guarantee security and convenience and the controllability of operation; igniter 3 and Pneumatic butterfly valve 2 are all by long-range PC remote control; when furnace of calcium carbide breaks down the emptying furnace gas of needs; long-range PC chain unlatching Pneumatic butterfly valve 2 and igniter 3 successively; carbon monoxide a large amount of in furnace gas is burnt, protected environment.
Above embodiment is not limited only to protection domain of the present utility model, all based on basic thought of the present utility model, modify or change all belong to protection domain of the present utility model.
