Abstract
The utility model discloses a kind of blast furnace pressure-equalizing and discharging sound damper deashing device, comprise the deashing pipeline that be connected through with pressure-equalizing and discharging sound damper sidewall and the collection box being fixedly mounted on deashing pipe end, in the middle part of described deashing pipeline, fixedly mount hand stop valve, by installing deashing pipeline at blast furnace pressure-equalizing and discharging sound damper sidewall bottom, hand stop valve installed by deashing pipeline, at deashing pipe end, collection box is installed, when sound damper normally uses, hand stop valve is in normally open, the blast furnace dust that the gas of pressure equalizing blow off valve discharge carries enters in collection box by deashing pipeline and hand stop valve, the dust cleaning cycle in collection box is estimated according to blast furnace service condition, when needing to clear up the dust in collection box, first hand stop valve is closed, then the hermatic door deashing of collection box side is opened, hermatic door is closed after deashing, then hand stop valve repeated collection dust is opened, without the need to deashing after damping down, guarantee that sound damper normally uses.
Description
Technical field
The utility model relates to blast furnace pressure-equalizing and discharging sound damper supplementary unit technical field, particularly relates to a kind of blast furnace pressure-equalizing and discharging sound damper deashing device.
Background technology
Sourdine is a kind of device stoping sound transmission and allow air-flow to pass through, and is the important measures eliminating air power noise.The device of the reduction noise on the gas channel that sourdine is mounted in air powered equipment (as gas blower, air compressor machine) or in inlet and exhaust system.Sourdine can stop sound wave propagation, and allowing air-flow to pass through, is the effective tool of control noises.
All pressure sourdine is the one in sourdine, is reduced the object of noise by the control realization of pressure.All press sourdine system impedance composite, inner sound absorption element can be changed flexibly, can be supporting with the blast furnace pressure equalizing blow off valve of different size.
Existing blast furnace pressure-equalizing and discharging sound damper in use, all will once all be pressed toward blowing in stove each time, for reducing by all pressing the noise brought during emission gases, at present at pressure equalizing blow off valve end, has all installed sound damper; But carry under one's arms blast furnace dust in the gas of pressure equalizing blow off valve discharge, long-time dust can be accumulated in sound damper, must carry out deashing to sound damper in some cycles, cleaning sound damper dust stratification work now, needs to carry out during blast furnace staying, manually open sound damper manhole, cleaning dust stratification, if the long-time not damping down of blast furnace, dust stratification will block sound damper, bring unnecessary damping down to blast furnace, impact is normally produced.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of blast furnace pressure-equalizing and discharging sound damper deashing device, at blast furnace pressure-equalizing and discharging sound damper sidewall bottom, deashing pipeline is installed, hand stop valve installed by deashing pipeline, at deashing pipe end, collection box is installed, when sound damper normally uses, hand stop valve is in normally open, the blast furnace dust that the gas of pressure equalizing blow off valve discharge carries enters in collection box by deashing pipeline and hand stop valve, the dust cleaning cycle in collection box is estimated according to blast furnace service condition, when needing to clear up the dust in collection box, first hand stop valve is closed, then the hermatic door deashing of collection box side is opened, hermatic door is closed after deashing, then hand stop valve repeated collection dust is opened, deashing process can carry out at any time, without the need to deashing after damping down, guarantee that sound damper normally uses.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of blast furnace pressure-equalizing and discharging sound damper deashing device, comprise the deashing pipeline that be connected through with pressure-equalizing and discharging sound damper sidewall and the collection box being fixedly mounted on deashing pipe end, in the middle part of described deashing pipeline, fixedly mount hand stop valve.
Described deashing pipeline head end is fixedly mounted on pressure-equalizing and discharging sound damper sidewall bottom and sealing is installed.
Described collection box is rectangular box structure, and hermatic door is installed in side to one, and this rectangular box structure roof is provided with exhaust outlet, arranges dedusting central layer inside this exhaust outlet.
The beneficial effect adopting technique scheme to produce is: by installing deashing pipeline at blast furnace pressure-equalizing and discharging sound damper sidewall bottom, hand stop valve installed by deashing pipeline, at deashing pipe end, collection box is installed, when sound damper normally uses, hand stop valve is in normally open, the blast furnace dust that the gas of pressure equalizing blow off valve discharge carries enters in collection box by deashing pipeline and hand stop valve, the dust cleaning cycle in collection box is estimated according to blast furnace service condition, when needing to clear up the dust in collection box, first hand stop valve is closed, then the hermatic door deashing of collection box side is opened, hermatic door is closed after deashing, then hand stop valve repeated collection dust is opened, deashing process can carry out at any time, without the need to deashing after damping down, guarantee that sound damper normally uses.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, sound damper; 2, hand stop valve; 3, collection box.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
For solving existing blast furnace pressure-equalizing and discharging sound damper in use easy collection ash and affect normal use, and deashing needs to carry out under damping down state, the normal problem of producing of impact, the utility model provides a kind of blast furnace pressure-equalizing and discharging sound damper deashing device as shown in Figure 1, comprise the deashing pipeline that be connected through with pressure-equalizing and discharging sound damper 1 sidewall and the collection box 3 being fixedly mounted on deashing pipe end, in the middle part of described deashing pipeline, fixedly mount hand stop valve 2; Described deashing pipeline head end is fixedly mounted on pressure-equalizing and discharging sound damper 1 sidewall bottom and sealing is installed; Described collection box 3 is rectangular box structure, and hermatic door is installed in side to one, and this rectangular box structure roof is provided with exhaust outlet, arranges dedusting central layer inside this exhaust outlet.
In embody rule process, by installing deashing pipeline at blast furnace pressure-equalizing and discharging sound damper sidewall bottom, hand stop valve installed by deashing pipeline, at deashing pipe end, collection box is installed, when sound damper normally uses, hand stop valve is in normally open, the blast furnace dust that the gas of pressure equalizing blow off valve discharge carries enters in collection box by deashing pipeline and hand stop valve, the dust cleaning cycle in collection box is estimated according to blast furnace service condition, when needing to clear up the dust in collection box, first hand stop valve is closed, then the hermatic door deashing of collection box side is opened, hermatic door is closed after deashing, then hand stop valve repeated collection dust is opened, deashing process can carry out at any time, without the need to deashing after damping down, guarantee that sound damper normally uses.
