The sweeping valve is connected with a short sweeping pipe, wherein screw threads are respectively arranged at two ends of the short sweeping pipe; and the front end of the short sweeping pipe is connected with a nozzle, and the rear end of the short sweeping pipe is connected with a water inlet pipe which is provided with a water inlet valve. The ash removing device has simple structure and can effectively remove the accumulated dust of the blast furnace gas pipe.
Description
Technical field
The utility model relates to a kind of deashing device of field of metallurgy, blast furnace gas pipe deashing device specifically.
Background technology
The generation of blast furnace gas almost runs through the whole process that blase furnace cast iron is smelted, and in this process, complicated physics and chemical transformation are being carried out in various participation materials each zone in stove, finally forms the pig iron and slag at furnace bottom, produces blast furnace gas at furnace roof.Blast furnace gas contains a large amount of ash contents, though through the dedusting of dust removal installations such as gravitational precipitator, washing tower, Wen's pipe precipitator, the half purified gas dustiness that blast furnace gas is responsible for is still up to 30mg/m
3About, along with the decline of gas temperature, the water vapor condensation in the coal gas forms the phlegma that contains ash, is deposited on duct bottom, accumulates over a long period, and it is stifled to form ash.To the blast furnace gas tee branch, ash is stifled to make the gas pipe runner become narrow, and flow diminishes, and the arm butterfly valve is not opened, closes not dead, blind plane operation need step-down and also be difficult to take out stifled etc., to producing and all very unfavorable safely.In the prior art, there is not a kind of device grey the blocking up of blast furnace gas pipe effectively to remove.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming that above prior art exists, propose a kind of simple in structurely, can handle the blast furnace gas pipe deashing device that play active effect to dust stratification.
The technical scheme that the utility model solves above technical problem is:
Blast furnace gas pipe deashing device comprises manhole and blow down valve, is connected to the purging short tube that a two is equipped with screw thread on blow down valve, and the front end that purges short tube is connected to nozzle, and back-end sealing is connected to water inlet pipe, and water inlet pipe is provided with water intaking valve.
Blast furnace gas pipe deashing device of the present utility model, the front end that purges short tube can be according to the nozzle of gas line caliber size designated length by one of pipe nipple connection.The rear end that purges short tube is connected to a plug, and joins by screw thread with plug, has the prosopyle in the middle of the plug, inserts a water inlet pipe in the prosopyle, and joins with the water inlet pipe sealing.
The utility model has the advantages that: the utility model is simple in structure, can effectively remove blast furnace gas pipe dust stratification.Can make that viscosity is stronger in the gas ash mud is at first diluted to come out, make the sand in the gas ash become loose, use the hand hammer vibrating conduit, loose sand just caves in and water mixes the formation fluid and enters hydathode and derived.The utility model can be removed the blast furnace gas outlet stool effectively and diffuse the dust stratification that tower is imported and exported pipeline, and the life cycle that also can prolong butterfly valve relatively also can handle playing a positive role to the dust stratification at coal gas tee branch place.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, a kind of blast furnace gas pipe deashing device comprises manhole 3 and blow down valve 4, on blow down valve 4, be connected to a two and be equipped with the purging short tube 5 of screw thread, the front end that purges short tube 5 is connected to nozzle 1, and back-end sealing is connected to water inlet pipe, and water inlet pipe is provided with water intaking valve 7.The front end that purges short tube 5 can be according to the nozzle 1 of gas line caliber size designated length by one of pipe nipple 2 connection.The rear end that purges short tube 5 is connected to a plug 6, and joins by screw thread with plug 6, has the prosopyle in the middle of the plug 6, inserts a water inlet pipe in the prosopyle, and joins with the water inlet pipe sealing.Blow down valve 4 is DN50 blow down valves, and water intaking valve 7 is water intaking valves of DN15, and water inlet pipe is the DN15 steel pipe.
The utility model is when concrete the installation, take off the tube drawing that moves back behind the DN50 blow down valve 4 of gas line manhole 3, be replaced with two the purging short tube 5 of screw thread is all arranged, the plug 6 that purges 5 one of short tubes and be complementary is tightened, open the aperture of DN15 in the middle of the plug 6, insert DN15 steel pipe and the tapping weldering is dead in the aperture, tail end is adorned the water intaking valve 7 of a DN15.The front end that purges short tube 5 connects the nozzle 1 that differs according to gas line caliber size designated length one by one with pipe nipple 2.The operating personnel only need wear a gas mask, and opens the blow down valve 4 on the manhole 3, with the utility model manhole 3 of packing into, utilizes the rotation of plug 6 screw threads, regulates muzzle to required direction.Connect high pressure water with metallic hose, open water intaking valve 7, orientation is carried out in the gas line bottom spray, the plaster of duct bottom is washed away, and the formation fluid enters hydathode and derived.
Equally, also can and diffuse tower and import and export behind the valve of pipeline and on the manhole the utility model is installed at the blast furnace gas outlet stool, regularly duct bottom and butterfly valve plate are carried out high pressure water sprinkling cleaning, the blast furnace gas outlet stool be can remove effectively and the dust stratification that tower is imported and exported pipeline, the life cycle that also can prolong butterfly valve relatively diffused.At the blast furnace gas outlet stool that does not have manhole and diffuse tower and import and export on the valve preceding pipeline of pipeline, also can adopt band to press the mode of punching, gate valve more than the corresponding position of arm installation DN50, can insert the utility model equally, the pipeline dust stratification is sprayed, also can obtain identical effect.Gaspipe network is dendroid and distributes, and branch gas tube is a lot, and As time goes on tee branch interface dust stratification problem will display one by one, and utilization of the present utility model handles to play a positive role to the dust stratification at coal gas tee branch place.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
