Abstract

A kind of device that can improve Combustion of Hot Air Furnace valve service life, belongs to blast furnace ironmaking hot-blast furnace equipment technical field, for improving Combustion of Hot Air Furnace valve service life.Its technical scheme is:Sedimentation basin is installed in the gas piping bottom of Combustion of Hot Air Furnace valve anterior connection, shower nozzle is installed in the front gas piping of sedimentation basin, shower nozzle is connected with spray header.The utility model is mounted with sedimentation basin and shower nozzle in the front gas piping of combustion valve, shower nozzle is connected with spray header, impurity in coal gas was deposited in sedimentation basin before combustion valve is entered by water spray, reduce the deposition at combustion valve position, enable that combustion valve is closed tightly, prevent gas leak from major accident occurring, while also extending combustion valve service life, save maintenance cost.It is the utility model simple structure, easy to install, prevent unsafe incidents, hot-blast stove operating rate is improve, wind-warm syndrome is improve, it is that blast furnace high yield, consumption reduction lay the foundation.

Description

A kind of device that can improve Combustion of Hot Air Furnace valve service life
Technical field
The utility model is related to a kind of device that can improve Combustion of Hot Air Furnace valve service life, belongs to blast furnace ironmaking hot blast Furnace apparatus technical field.
Background technology
A part of low cost feedstock is eaten, it is necessary to match somebody with somebody in blast furnace ironmaking process, the impurity of these raw materials is more, is smelting Cheng Zhong, a part of impurity enters gaspipe network with blast furnace gas.Hot-blast stove when burning stove is carried out using pipe network coal gas, blast furnace gas In an impurity part be deposited on burning valve base in, a part stick on the valve plate of combustion valve.Burnt during hot blast stove burning Valve is opened, and coal gas enters burning in hot-blast stove.When hot-blast stove is blown, combustion valve is in the closed position, seals the heat in hot-blast stove Wind, separates with gas piping.If the impurity deposited in combustion valve excessively, will result in, and combustion valve is poorly sealed, hot-blast stove exists During air-supply, hot blast leaks into branch gas tube from combustion valve in stove, and the gas stop valve before combustion valve is not closed completely leakage coal In the case of gas, will mix in hot-blast stove branch gas tube, form explosive mixed gas, it is most likely that gas explosion thing occurs Therefore.Therefore, combustion valve site deposition thing how is reduced, combustion valve service life is improved, just must as relevant technical staff The problem that must be solved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Combustion of Hot Air Furnace valve service life of can improving Device, this device can effectively reduce combustion valve site deposition thing, extend combustion valve service life.
Solving the technical scheme of above-mentioned technical problem is:
A kind of device that can improve Combustion of Hot Air Furnace valve service life, it includes spray header, shower nozzle and sedimentation basin, Sedimentation basin is installed in the gas piping bottom of the anterior connection of Combustion of Hot Air Furnace valve, and shower nozzle is installed in the front gas piping of sedimentation basin, Shower nozzle is connected with spray header.
Sewage draining exit, blowdown are arranged at the above-mentioned device that can improve Combustion of Hot Air Furnace valve service life, the bottom of the sedimentation basin Mouth is provided with sewage draining valve.
The above-mentioned device that can improve Combustion of Hot Air Furnace valve service life, the shower nozzle is multiple, and multiple shower nozzles are arranged on The top of gas piping inwall, spray header is connected with hydraulic pipeline, and control valve is provided with spray header.
The beneficial effects of the utility model are:
The utility model is mounted with sedimentation basin and shower nozzle, shower nozzle and spray header phase in the front gas piping of combustion valve Connection, the impurity in coal gas was deposited in sedimentation basin before combustion valve is entered by water spray, was reduced in the heavy of combustion valve position Product so that combustion valve can be closed tightly, prevents gas leak from major accident occurring, while also extending the combustion valve operation longevity Life, has saved maintenance cost.It is the utility model simple structure, easy to install, prevent unsafe incidents, improve hot blast Stove operating rate, improves wind-warm syndrome, be blast furnace high yield, consumption reduction lay the foundation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows:Gas piping 1, combustion valve 2, spray header 3, shower nozzle 4, sedimentation basin 5, sewage draining exit 6, blowoff valve Door 7.
Specific embodiment
The utility model is made up of spray header 3, shower nozzle 4, sedimentation basin 5, sewage draining valve 7.
Shown in figure, spray equipment, spray equipment are installed in the gas piping 1 of the anterior connection of Combustion of Hot Air Furnace valve 2 Coal gas is sprayed water, be wrapped in the impurity in coal gas in water droplet and fall by water smoke, prevent the impurity in coal gas from entering combustion valve 2 Be deposited on combustion valve 2.
Shown in figure, multiple shower nozzles 4 of spray equipment are arranged on the top of the inwall of gas piping 1, spray header 3 and water delivery Pipeline is connected, and control valve is provided with spray header 3.Need coal gas enter hot-blast stove in burn when, while open control Valve processed is sprayed water, the impurity in decontamination coal gas;When hot-blast stove is blown, combustion valve is in the closed position, now without coal Flow of air, can close the control valve of shower nozzle, using water wisely.
Shown in figure, sedimentation basin 5 is installed in the bottom of the gas piping 1 between spray equipment and combustion valve 2, miscellaneous in coal gas Matter enters in sedimentation basin 5 after falling the bottom of gas piping 1 with current.
Shown in figure, sewage draining exit 6 is arranged at the bottom of sedimentation basin 5, and sewage draining exit 6 is provided with sewage draining valve 7.Blowoff valve is opened in timing The impurity discharge that door 7 will be precipitated.
