Description
Technical field:
The utility model relates to cleaning apparatus.
Background technology:
At present, coking industry is generally applied Dry Quenching Technology, recycles red burnt sensible heat to greatest extent, for enterprise creates good economy and environmental benefit.Wherein, the environmental dust removal station through the dusty gas that produces in the dry coke quenching auxiliary operation process is focused on, reduces being discharged into the dust granules thing quantity in the atmosphere as important component part, avoids taking place secondary pollution.Its collected dusty gas mainly divides two kinds, and the one, charging apparatus, furnace roof diffuse the high-temperature flue gas of mouth, chamber pressure adjusting place that prestores, and the 2nd, the low-temperature flue gas of vibratory feeder, rotary seal valve, belt reloading point, final dusting ash Cang Chu.Its technical process is to produce suction through dedusting fan, drives flue gas and gets into pulsed jet cloth filter, filters out the dust granules thing, enters atmosphere after flue gas is up to standard.PM for particulate matter is that coke powder falls into the dedusting ash storehouse, is transported to ash-storing bin through double-deck ash-valve, scraper conveyer.The dedusting ash storehouse is the transhipment station of whole flow process, plays the effect of buffering and storage, directly has influence on the continuous operation ability of environmental dust removal system.
The dedusting ash storehouse is the shell structure of a weldering system, is made up of the opening for feed that is provided with on warehouse, warehouse cover plate, the cover plate, viewport, capacitance level meter, warehouse bottom discharge port, form ash-valve.Warehouse top is equipped with capacitance level meter, and coke powder material level in the storehouse is monitored, and with the computer real-time communication of master control room, is beneficial to operator's situation that in time notes abnormalities, and deals with rapidly.The basic composite structure of going up cone tube under the circle tubular body arranged inside that adopts of warehouse design is formed an integral body through welding between the top and the bottom of structure, and the angle of junction changes suddenly, and the curved resistance of fluidic is sharply risen.Ring flange of the external round top welding of last pipe shape; Ring flange is placed in the circular hole external diameter that dust removing station tail end face is provided with, and upward round tubular body arranged inside hypomere is enclosed within the deck below, and upward round tubular body arranged inside hypomere axial length is greater than the epimere axial length; The tapering of following cone tube is bigger, and 90 degree are arranged approximately.In addition, the obliquity of tapered section is not enough, and the tractive force that coke powder falls is less.The ash storehouse runs into severe weather conditions such as rainy day in actual use, contains too much water vapor in the flue gas, and coke powder humidity rises, and viscosity increases, and flowability weakens, and very easily forms bulk in the junction, top and the bottom and hardens, and causes grey storehouse to stop up.After coke powder hardened in the ash storehouse, the manual handling difficulty was bigger, needed the time of cost longer.Need carry out the warehouse cutting when serious, manually remove the part that hardens.In the treating processes, the coke powder of whereabouts can form airborne dust, brings secondary pollution.Simultaneously; After coke powder accumulates to a certain degree in the ash storehouse; Can cause the little bucket of chapelet draw bad, scraper ash-transmission machine Yin Lali is excessive and break, spiral ash machine is stuck; Can have influence on the normal operation of environmental dust removal system what is more, the pressure reduction that causes fly-ash separator to import and export increases, and the watt consumption of dedusting fan increases.When pressure reduction surpassed the setting limit value, the chain control of meeting initiating system threatened its operating safety.The dust-removal system running is undesired, and dust content after filtering can obviously increase, and the rotor wear of dedusting fan speeds up, and shortens its work-ing life, and the equipment amortization cost rises greatly.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and a kind of dry coke quenching environmental dust removal ash chamber structure is provided.
The utility model scheme is: be made up of the opening for feed that is provided with on warehouse, warehouse cover plate, the cover plate, viewport, capacitance level meter, warehouse bottom discharge port, form ash-valve; It is characterized in that: going up of warehouse upwards foreshortens to concordant welding fixed flange in back with dust removing station deck upper surface along the axial length under the circle tubular body arranged inside; After following cone tube axial length upwards extended, the upward circle tubular body arranged inside lower edge after its upper edge and the shortening was welded and is fixed; Be drilled with a through hole in following cone tube bottom, fixing inlet pipe on the said through hole, inlet pipe is communicated with the high pressure gas source capsule through an intake valve.
The advantage of the utility model is:
1, the novel grey storehouse of dry coke quenching environmental dust removal inferior pyramidal body is elongated, and cone angle diminishes, and helps coke powder discharging automatically under action of gravity.
2, the vibrator that installs additional of the both sides in dry coke quenching environmental dust removal ash storehouse helps coke powder and glides and discharge, and practices thrift ash discharge and uses electric energy and time.
3 even stifled bucket situation takes place once in a while, can start at the same time under the situation of vibrator, be interrupted the butterfly valve of opening the bottom and feed pressurized air, form air bubble, make the grey piece that the hardens pine that shakes, be easy to solve stifled bucket problem.
