Description

Ladle-pot hot-repair station flue gas trapping collecting by filtration integrated apparatus
Technical field
The utility model relates to dedusting technology field, particularly relates to the flue gas dust collecting system of a kind of hot repair job contract position.
Background technology
The residue remained in after toppling over molten steel in ladle needs to clean out.Post workman boiling water gap and cleaning clinker process in permeate into contaminated environment in air along with a large amount of high-temperature smokes.Hot repair job contract position dust pelletizing system is included in workshop in secondary BOF dedusting system main system usually, separates a road arm for hot repair job contract position in main system pipeline.But because main system is mainly according to the configuration of converter secondary air flow, hot repair bag dedusting air quantity only accounts for a very little part for main system dedusting air quantity.And due to plant process layout, converter electrical secondary system is also more difficult when balance respectively removes dirt pits resistance.Cause the dust removing effects of hot repair job contract position undesirable, capture rate is not high.Moreover, a hot repair job contract more than place usually, position, and be intermittent work, if be included in converter dust-removing main system, when hot repair bag does not work, air quantity can be caused to waste, loss of energy, if main system adopts frequency control to run, other significantly decline except dirt pits arresting efficiency certainly will to cause converter.For this reason, hot repair bag flue gas trapping filtering integral device just solves the problem well, and has the following advantages: 1 device is for portable, and applying flexible is reliable, starts at any time and applies at any time, meet current energy-saving and emission-reduction policy.2 is dedusting on the spot due to what take, and be not be included into converter main system, such system flow is short, and resistance is low, and design air flow is little, the less energy consumption that unit air volume needs.3 devices itself are also good heat insulation safeguards, and while solving smoke pollution, this device also carries out heat insulation protection to post workman effectively.The arc light produced when high-temperature flue gas and work is avoided to damage workman.
Utility model content
For solving the problems of the technologies described above, the utility model provides with a kind of ladle-pot hot-repair station flue gas trapping collecting by filtration integrated apparatus.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of ladle-pot hot-repair station flue gas trapping collecting by filtration integrated apparatus, it comprises main body, described main part is upper and lower two parts, the latter half of described main part is partitioned into by deflector the air-flow that supplied gas passes into and passes into passage and dedusting passage, the side-lower that described air-flow passes into passage is provided with side seal board, and the top of side seal board is provided with soft sealer; The lower end of described dedusting passage is provided with blower unit, is provided with dust collecting installation directly over described blower unit; The first half of described main part is absorbing cover, passes into that passage side is oblique is provided with fire retardant device in described absorbing cover near air-flow; One end, bottom side of described main part is provided with control centre.
Preferably, the side seal board that described air-flow passes into passage passes into air-flow the structure that the recessed overall structure making to circulate into passage inside passage forms an inside collecting.
Preferably, the below of described main part is provided with mobile wheel device.
Preferably, described dust collecting installation comprises ash bucket, and the lower end of described ash bucket is provided with hand operated gate valve, and the lower end of described hand operated gate valve is provided with storage ash-pit.
Preferably, described air-flow passes into and obliquely in passage is provided with deflector.
Preferably, described blower unit is air-introduced machine.
The beneficial effect that the utility model obtains is, docked with ladle by side seal board in this ladle-pot hot-repair station flue gas trapping collecting by filtration integrated apparatus, residue in ladle is rooted out by drill rod by workman, simultaneously blower unit produces and attracts air-flow the dust in ladle to be introduced air-flow to pass in passage and with this through absorbing cover and dust arrester, dust to be absorbed; The below of main part can be provided with mobile device, promote ladle-pot hot-repair station flue gas trapping collecting by filtration integrated apparatus conveniently moving to multiple ladle dedusting.In the present invention, deflector is with the effect of protective separation, and overflow from ladle mouth side because post workman produces volume of smoke at boiling water gap and when cutting clinker, therefore deflector carries out heat insulation protection to post workman effectively.The arc light produced when high-temperature flue gas and work is avoided to damage workman.
