Description
Technical field
The utility model relates to and a kind of flue gas in the convertor steelmaking process is carried out the device of cooling and dedusting, specifically a kind of converter gas purification treatment system.
Background technology
The converter gas treatment process is an important means that realizes the steel-making of negative energy, environment protection and energy-saving and water-saving.Existing converter gas purification reclaims technology and mainly includes two kinds of dry process and wet processings, wet processing wherein is flue gas to be washed in the two-stage Venturi meter by excessive water, to reach the dust separating purification purpose of cooling, again according to the analysis of smoke components, carry out the recovery of coal gas or diffuse by the T-valve group.
Used one-level Venturi meter is the overflow Venturi meter, and used secondary Venturi meter is a RD aditus laryngis Venturi meter.One-level overflow Venturi meter has the defective that equipment resistance is big, energy consumption is high and water consumption is big; The RD valve of secondary RD aditus laryngis Venturi meter is fouling and non-adjustable easily in use.In addition, the used drain water seal of wet processing is easily wrapped up in band coal gas, and potential safety hazard is bigger.
The utility model content
The purpose of this utility model just provides a kind of converter gas purification treatment system, and decontamination effect improving and recovery quality with effective raising flue gas reduce water consumption.
The utility model is achieved in that a kind of converter gas purification treatment system, system's prime is the spray evaporation cooling tower, the exhanst gas outlet of up circumferential weld Venturi meter and described spray evaporation cooling tower joins, and described up circumferential weld Venturi meter is upright by top, the pipe connecting of lower knuckle connects the eddy flow water trap; Be respectively equipped with drain water seal below the described eddy flow water trap with below the described pipe connecting bending section; Above described spray evaporation cooling tower, be provided with the transpiration cooling gun system, on the cone of the top of described spray evaporation cooling tower, be provided with cooling Washing spray nozzle system, in described up circumferential weld Venturi meter, be connected to circumferential weld Venturi nozzle system, in described eddy flow water trap, be connected to the dehydration nozzle.
Described spray evaporation cooling tower is connected by the gasification cooling flue of non-metal expansion joint with the transmission converter gas, the spray evaporation used for cooling tower is in efficiently cooling off converter gas and thick dedusting, and circumferential weld Venturi meter and eddy flow water trap are used for converter gas is finally cooled off and smart dedusting.
The utility model has replaced traditional one-level overflow Venturi meter with the spray evaporation cooling tower.About 300～the 500Pa of the systemic resistance of spray evaporation cooling tower, the about 4000Pa of resistance of tradition one-level overflow Venturi meter, so not only can reduce systemic resistance 3000Pa, and, because the reduction greatly of the air-flow velocity in the spray evaporation cooling tower had both helped carbonated drink separation, also make air-flow can not impact the drain water seal of bottom, drain water seal is also just no longer wrapped up in band coal gas, and potential safety hazard is eliminated.
Adopt up circumferential weld Venturi meter to replace traditional RD aditus laryngis Venturi meter, cancelled the complex construction that nitrogen is disclosed pin, and press interlocking, reduce the burning of flue gas, can farthest reclaim coal gas at fire door with the fire door elementary errors.In addition, because systemic resistance greatly reduces behind the configuration spray evaporation cooling tower, under the identical situation of fan capacity, the resistance of system can be redistributed, up circumferential weld Venturi meter can increase pressure reduction, and the speed when air communication is crossed aditus laryngis thereby be improved obviously improves smart dust separating effect.The interlocked control that up circumferential weld Venturi meter and fire door elementary errors are pressed guarantees that fire door pressure at 0～20Pa, can farthest reduce the burning of flue gas, guarantees the high yield of coal-gas recovering and high-quality.
In the eddy flow water trap, increase the dehydration nozzle, can remove part mechanical water and part vaporize water, improve dewatering efficiency, and can reduce dust in flue gas concentration, improve the cycle of operation of dedusting fan.
Water consumption to the transpiration cooling gun system above the spray evaporation cooling tower, can be according to the different steps exhaust gas volumn of converter steelmaking, the different characteristics of flue-gas temperature, adopt the PID mode to regulate service discharge, can avoid like this supplying water, realize the water saving purpose by traditional maximum service discharge.This measure also can make the whole transpiration coolings of water, and flue-gas temperature is reduced to 200 ℃.
Be connected on the cooling Washing spray nozzle system on spray evaporation cooling tower top, flue-gas temperature can be reduced to 70 ℃, and the washing flue gas.This cooling Washing spray nozzle system also can adopt PID to regulate the control water.Circumferential weld Venturi nozzle system then can adopt control stage by stage to supply water, and realizes maximized water saving thus.
The utility model is provided with the eddy flow impeller in the upper port of described pipe connecting, by increasing the impeller dehydration, improve dewatering efficiency.
The utility model is provided with baffle plate in the bending section of the lower end of described pipe connecting, so that the moisture content in the flue gas is discharged in advance, alleviate the load of eddy flow water trap.
The water shoot that is connected on described eddy flow water trap below and is connected on the drain water seal of described pipe connecting bending section below connects the water tank of a band tapered bottom altogether, and the rising pipe of the water pump that joins with water tank is connected to the waterworks of described spray evaporation cooling tower.Like this, the water that pipe connecting and eddy flow water trap are discharged just can enter water tank by drain water seal, the conical lower portion of water tank is convenient to spoil disposal, and the water behind the water tank inner filtration uses for the spray evaporation cooling tower after the water pump pressurization, and the water that spray evaporation cooling tower below drain water seal is discharged enters discharge channel.Form tandem water supply unit and cycling use of water thus, reduced outside service discharge.
The utility model is simple and reasonable, and water consumption is few; Spraying mist and steam cooling tower resistance is little, and flue gas flow rate is little in the tower, and band coal gas is not wrapped up in water seal, and is safe in utilization; After increasing the impeller dehydration and increase the dehydration nozzle in the eddy flow water trap, its dehydrating effect is better.The utility model is suitable for installing and using in various converters.
