Abstract

The utility model provides a one-time dry quenching dust collector with a composite retaining wall. The one-time dry quenching dust collector comprises a dust removal channel, wherein a dust hopper is arranged on the bottom surface of the dust removal channel, an upper retaining wall is arranged at the top of the dust removal channel above the dust hopper, and the height h1 of the upper retaining wall is 40 percent to 70 percent of the height h2 of the inner diameter of the dust removal channel. The dust collector does not need to control the circulation gas flow accurately; the flow direction of the circulation gas is not changed; the gas flow resistance is weak, so as not to cause affection on the pressure balance of a dry quenching system; and as the impact of the circulation gas on the retaining wall is weaker, the service life of the one-time dust collector is prolonged.

Description

The cork dry quenching disposable dust remover that has compound barricade
Technical field
The utility model relates to a kind of fly-ash separator, specifically a kind of cork dry quenching disposable dust remover that has compound barricade.
Background technology
Cork dry quenching disposable dust remover is the dried connecting passage that puts out between stove and the waste heat boiler; Mainly undertake the task of dry coke quenching inertia recycle gas primary dust removing; To reduce the wearing and tearing of coke powder to the waste heat boiler heat pipe; Existing cork dry quenching disposable dust remover mainly is to remove the meal dirt in the recycle gas through the gravity settling mode, wherein is divided into the band barricade and is not with two kinds of structure formations of barricade.Can only not lean on the weight sedimentation of dust self, production stability is had relatively high expectations, must control the recycle gas flow well with the disposable dust remover of barricade; The disposable dust remover of tradition band barricade inserts the barricade lower end in the ash bucket, blocks fully with the gas channel of barricade with fly-ash separator, forces gas stream through ash bucket; Accomplish sedimentation, but the disposable dust remover of this band barricade has changed the recycle gas flow direction, when improving efficiency of dust collection; Also significantly increased the gas flow resistance; Pressure equilibrium exerts an influence to dry quenching system, and barricade receives recycle gas bump, and work-ing life is shorter.
The utility model content
The purpose of the utility model provides a kind of cork dry quenching disposable dust remover that has compound barricade; It does not need the recycle gas flow is accurately controlled; Do not change recycle gas and flow to, the gas flow resistance is less, can not exert an influence to the dry quenching system pressure equilibrium; A little less than barricade receives the recycle gas surging force, the work-ing life that helps improving disposable dust remover.
The utility model is for realizing above-mentioned purpose, and realize through following technical scheme: comprise the dedusting passage, the dedusting passage bottom is provided with ash bucket, and the dedusting channel roof of ash bucket top is provided with top retaining wall, and the height h1 of top retaining wall is the 40%-70% of dedusting passage internal diameter height h2.The height h1 of top retaining wall is 55% of dedusting passage internal diameter height h2.The dedusting passage bottom is provided with lower retaining wall.
The advantage of the utility model is: do not need the recycle gas flow is accurately controlled; Do not change recycle gas and flow to, the gas flow resistance is less, can not exert an influence to the dry quenching system pressure equilibrium; A little less than barricade receives the recycle gas surging force, the work-ing life that helps improving disposable dust remover; Can prevent that the dust in the ash bucket from being gone into disposable dust remover etc. by back suction.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is the left TV structure synoptic diagram of Fig. 1.
Embodiment
The described cork dry quenching disposable dust remover that has compound barricade of the utility model comprises dedusting passage 1; Dedusting passage 1 bottom surface is provided with ash bucket 2; It is characterized in that: dedusting passage 1 top of ash bucket 2 tops is provided with top retaining wall 3, and the height h1 of top retaining wall 3 is the 40%-70% of dedusting passage 1 internal diameter height h2.Top retaining wall 3 only blocks portion of channel, and gas is play the guiding role, and makes the intravital dust of circulation gas through in inertial settling to the ash bucket 2; Do not change recycle gas and flow to, learn through the simulated experiment of disposable dust remover internal gas flow: when disposable dust remover inlet recycle gas flow velocity at 9 ~ 12m/s, the top retaining wall height is disposable dust remover inner section height 40 ~ 70% o'clock; For the above particle of 0.5mm, efficiency of dust collection reaches more than 85%, and the whole efficiency of dust collection of disposable dust remover reaches 40 ~ 50%; Resistance only increases by 100 ~ 150Pa; Can not exert an influence to the dry quenching system pressure equilibrium, a little less than barricade receives the recycle gas surging force, the work-ing life that helps improving disposable dust remover.
The height h1 of the said top retaining wall 3 of the utility model is the 40%-70% of dedusting passage 1 internal diameter height h2; The height of top retaining wall 3 can adopt the arbitrary value in this scope, if but the height of top retaining wall 3 is excessive, can increase the gas flow resistance; Influence the dry quenching system pressure equilibrium; If the height of top retaining wall 3 is too small, then can make in the recycle gas part dust can't sedimentation, influence efficiency of dust collection; Can have higher efficiency of dust collection not influencing on the pressure balanced basis of dry quenching system in order to ensure the utility model, the preferred version of its said top retaining wall 3 is: the height h1 of top retaining wall 3 is 55% of dedusting passage 1 internal diameter height h2.
When the dust in the ash bucket 2 was expired soon, the dust on surface can be gone into disposable dust remover by back suction under the air-flow effect, and the utility model is gone into disposable dust remover in order to prevent the dust in the ash bucket 2 by back suction, can lower retaining wall 4 be set in dedusting passage 1 bottom surface.Lower retaining wall 4 can play barrier effect to the dust of being gone into disposable dust remover by back suction in the ash bucket 2, makes dust fall into ash bucket 2 again, can not get into waste heat boiler along dedusting passage 1.
