Background technology
Along with the operation of blast fumance, there is the problem of body of heater cooling apparatus breakage in blast furnace region all to some extent, the water pipe of breakage must be cut off from original cooling system.Adopt the blast furnace of open return water system, part coal gas is carried in air via the water coolant of cooling blast furnace; Adopt the blast furnace of closed system, adopt service water maintenance after its water cooler breakage, a large amount of coal gas diffuses equally to blast furnace region.After process, although cooling apparatus is managed, the water yield of bleeding in stove is controlled, but still have a large amount of coal gas to be released in Work places, when damaged quantity is many, body of heater each layer platform gas concentration exceedes can operation or work standard, the life security of serious threat operating personnel.All bring potential safety hazard to the normal safe spot check operation in producing, maintenance and repairing upkeep operation etc.Take corresponding countermeasures effectively to be controlled to this part coal gas, could really accomplish to ensure safety in production.
Summary of the invention
The purpose of this utility model is to design coal gas processing device in the damaged water cooler water coolant of a kind of blast furnace, effectively reduce the gas concentration in blast furnace region, ensure that the personnel safety of this regional work personnel, guarantee that coal gas is abundant, homogenous combustion, reduce the remaining coal gas in surrounding environment.Make coal gas collection and treatment device can reach three to prevent, waterproof, windproof, anticreep fire.
For achieving the above object, the technical solution of the utility model is:
Coal gas processing device in the damaged water cooler water coolant of a kind of blast furnace, it comprises, a base plate; First, second gas and water separator, it is body structure, is arranged on described base plate, and be communicated with by a pipe connecting between two tanks, casing inner bottom part side vertically arranges water eliminator respectively; Wherein, water inlet pipe is established in the first gas and water separator side, this water inlet pipe sets gradually tensimeter and water inlet trip valve; Return water pipe is established in second gas and water separator side, this return water pipe is arranged backwater stopping valve; U-shaped communicating pipe, its two ends are arranged at first, second gas and water separator casing top described respectively; Gas export control, its lower end was connected in the middle part of described U-shaped communicating pipe, arranged tensimeter and coal gas stopping valve in gas export control pipeline; Burner, be arranged at described gas export control upper end, netted nose cone is established on burner top.
Further, described water eliminator is some horizontally disposed grille strip compositions.
Preferably, the downward-sloping layout of described grille strip.
Preferably, in the pipeline of described water inlet pipe and return water pipe, one end high pressure hose is set respectively.
Preferably, described base plate divides into roller.
Combustion detection device is established on described burner top.
Water coolant containing coal gas is imported custom-designed gas and water separator by the utility model, the mode of gas-water separation is adopted to collect coal gas, and adopt Thorough combustion gather the technological line of coal gas, coal gas can be separated with water and guide to safe position and carry out safe and effective process, effectively reduce the gas concentration in blast furnace region, ensure the personnel safety of this regional work personnel.
At the design aspect of coal gas burner, be provided with nose cone, guarantee that coal gas is abundant, homogenous combustion, reduce the remaining coal gas in surrounding environment, be provided with temperatuer detector simultaneously, remote reviewing in situ temperature (whether being greater than 80 DEG C) state of combustion of coal gas can be judged.
The utility model is applicable to adopt service water maintenance after blast furnace region adopts the water cooler breakage of the breakage of the water cooler of open backwater cooling system or airtight return water system, drainage head carries the situation of coal gas, effectively can realize being separated of coal gas and water coolant, and the gas concentration reduced rapidly in site environment, ensure the personnel safety of field personnel.
The beneficial effects of the utility model are,
The mode that the utility model adopts waterhead to realize gas-water separation is collected coal gas and carries out clean-burning technological line, coal gas can be guided to safe position and adopt clean-burning mode to process, significantly reduce the gas concentration in blast furnace region, ensure that the personnel safety of this regional work personnel.In addition, because gas pressure in stove is not by manual control, tensimeter and ball valve are set up, change for preventing gas pressure and cause tempering and de-fire, according to hydromechanical empirical value, have employed relevant coal gas fairlead caliber, at the design aspect of coal gas burner, be provided with decompression cover and nose cone, guarantee that coal gas is abundant, homogenous combustion, reduce the remaining coal gas in surrounding environment.Make coal gas collection and treatment device can reach three to prevent, waterproof, windproof, anticreep fire.
