Description
Technical field
The utility model belongs to the dewatering unit of metallurgy industry blast furnace gas, particularly the blast furnace gas tornado evaporator.
Background technology
At present, the blast furnace gas purification technology of metallurgy industry blast furnace production both at home and abroad mainly contains traditional wet dedusting technology and new-type dry dedusting technology.A large amount of dusts that traditional wet dedusting technology is can't be in removing blast furnace gas entrained reach≤10mg/m the purified gas dustiness
3Technical indicator the time, a large amount of mechanical waters is taken to user side by swiftly flowing coal gas, the device that is used for online coal gas draining at present mainly is water seal.When mainly being passive draining, the effect of water seal seals coal gas.The advantage of water seal be cost of manufacture little, make simple, easy to operate, safeguard easy etc.Its fatal shortcoming is: the mechanical water of carrying secretly in the coal gas is the droplet shape, because the water seal water port is less, the mechanical water that swiftly flowing coal gas is carried secretly has little time when passing through the water seal water port to discharge, thereby cause a large amount of water of user's burner mouth by high temperature evaporation, with the softening burner ingress that is bonded in of the small amount of dust of carrying secretly, stop up burner, influence is normally used.And when pipeline pressure generation unusual fluctuations, make effectively water level reduction in the water-sealed valve, cause the serious accident of leakage gas.
Blast furnace gas is a gas colourless, tasteless, inflammable and explosive, that severe toxicity is arranged, and CO content is 26～30%, and severe is about 1.25, and is approaching with air severe, about 550～600 ℃ of burning-point, the about 3971KJ/m of calorific value
3Must carry out in strict accordance with the regulation among the State Standard of the People's Republic of China GB622-2005 " industrial enterprise's gas safety rules " in the use.The person, equipment Serious Accident that domestic and international iron and steel enterprise takes place in using the blast furnace gas process are a lot.
Thermoelectric 2 * 130t/h boiler is coal/gas mixed burning boiler, and as energy-efficient equipment, blast furnace gas is as main fuel, and maximum is mixed and burnt than being 60%, and separate unit boiler maximum is mixed the burning amount can reach 60,000 m
3/ h.After going into operation in 2005, water-tube boiler is in using blast furnace gas, burner frequently stops up, coal gas is mixed the burning amount and is constantly reduced, and the frequency of the cleaning burner that stops burning gas is increasing, burner of cleaning in three days when the most serious, working strength is big, dangerous high, cause boiler coal consumption to rise simultaneously again, cost increases.Tracing it to its cause, is to cause because water content is excessive in the blast furnace gas.
Summary of the invention
The purpose of this utility model is to provide a kind of blast furnace gas tornado evaporator, can reduce the water content in the blast furnace gas, make boiler as often as possible use the byproduct blast furnace gas of blast furnace ironmaking, reduce the obstruction of boiler burner, reduce burner cleaning frequency, it is rational in infrastructure, and the dewatering efficiency height is easy to maintenance.
The purpose of this utility model is achieved in that a kind of blast furnace gas tornado evaporator, cylindrical tube with doline bottom surface, installing the output gas line by central through hole on the end face of its sealing, the end opening of output gas line extend into the intravital bottom of cylindrical drum, tangential direction at cylindrical tube upper inlet upper edge cylindrical drum body wall is being provided with gas pipe, and the end opening of doline bottom surface is connecting water shoot.
During the utility model work, coal gas with higher speed from advancing gas pipe, enter cylindrical tube along cylindrical drum body wall tangential direction, utilize coal gas at pipeline high speed mobile kinetic energy, coal gas tangentially enters cylindrical tube from the gas pipe that advances of the import on cylindrical tube top, high speed rotating under action of centrifugal force, water are wherein isolated and are collided by centrifugal power on the cylindrical drum body wall, flow to drainage pipeline along barrel wall to doline bottom surface, lower edge.The end opening of the output gas line that the coal gas after the dehydration installs from the cylindrical shell center enters the output gas line and delivers to user side.The utility model has reduced the water content in the blast furnace gas, makes boiler as often as possible use the byproduct blast furnace gas of blast furnace ironmaking, has reduced the obstruction of boiler burner, has reduced the cleaning frequency of boiler burner, and it is rational in infrastructure, and the dewatering efficiency height is easy to maintenance.
