Abstract
The utility model discloses a 125t/h dry quenching barricade-free one-time dust removing device, and relates to a dry quenching one-time dust removing device. The device comprises an arch top, a surrounding frame wall, a high-temperature expansion joint, a diffusion hole, a dust hopper, a water cooling sleeve and a dust removing valve, and is characterized in that: a dust removing barricade is not arranged in an inner cavity of the surrounding frame wall. The utility model has the advantages that: the dust removing barricade is not provided, so that construction difficulties and construction cost are reduced, and the phenomenon of the plugging of the dust hopper due to the falling and collapse of dust removing barricade bricks can be prevented; and coke powder is collected by using principles that the sectional area of air is increased, flow velocity is reduced and large particle coke powder obliquely falls due to dead weight, so that the dust removing effect of the one-time dust removing device cannot be influenced, substantial influences on abrasion and heat exchange of a boiler can be prevented, pressure loss of gas in the flowing process is reduced, and energy consumption is reduced.
Description
Technical field:
The utility model relates to cork dry quenching disposable dust remover.
Background technology:
Existing 125t/h cork dry quenching disposable dust remover by vault, enclose frame body of wall, high temperature expansion joint, diffuse the hole, ash bucket, water cooling sleeve pipe, ash-valve and dedusting baffle plate form.Enclose the frame wall enclosure by welded steel plate, the side is provided with into air outlet opening, and inside is built high-strength clay brick (QN3, QN53) and insulating brick by laying bricks or stones, and the heat insulation brickbat of filling part is covered with heat insulation cellucotton between brick and the steel plate.Advancing air outlet opening is connected with boiler with the dried stove that puts out through the high temperature expansion joint.The dedusting baffle plate is built by laying bricks or stones with wearing-proof refractory material and is formed; Perpendicular to vault with advance the air outlet opening axial line, it is roughly individual layer arch wall structure, its top, the left side, the right side link to each other with the disposable dust remover body of wall; The bottom extends to top, fly-ash separator ash storehouse, and the space is left with grey storehouse in dedusting baffle plate bottom.When the macrobead coke powder along with recycle gas strikes the dedusting baffle plate, the vanishing of coke powder horizontal velocity because self gravitation makes coke powder drop to the dedusting ash storehouse, recycle gas then passes through from dedusting baffle plate lower space, gets into boiler.It utilizes the gravitational dust collection principle, and (diameter >=0.5mm) separate reduces recycle gas to the erosive wear that generator tube (mainly being the secondary superheater pipeline) produces, and reaches the purpose of protection generator tube with the macrobead coke powder in the recycle gas.
The frequent heating and cooling of system that high temperature circulation gas percussion dedusting baffle plate and maintenance cause are easy to make dedusting baffle plate wall brick to become flexible, come off, and cause dedusting baffle plate integral body to be collapsed at last; The wall brick that comes off is deposited in the dedusting ash storehouse; Make coke powder pile with grey storehouse row and do not go out, cause a large amount of coke powders to get into boiler, quicken the wearing and tearing of generator tube; A large amount of coke powders are deposited on the generator tube, influence the boiler hot exchange.The dedusting baffle plate wall brick that at last must the blowing out cleaning collapses is discharged coke powder, time of this labor and bring very big financial loss.And the dedusting veneer also increased the pressure-losses of gas flow, strengthened and kept gas circulation mobile power consumption.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, provides a kind of 125t/h dry coke quenching not have the barricade disposable dust remover.
The utility model scheme is: comprise vault, enclose the frame body of wall, the high temperature expansion joint, diffuse hole, ash bucket, water cooling sleeve pipe, ash-valve, it is characterized in that: enclose frame body of wall inner chamber the dedusting baffle plate is not set.
The advantage of the utility model is: the dedusting barricade is not set; Reduce difficulty of construction and reduce construction cost, do not have coming off and the obstruction ash bucket that collapses of dedusting barricade brick, utilize the airflow sectional area to increase flow velocity and reduce the conduct oneself with dignity principle of oblique whereabouts of macrobead coke powder; Collect coke powder and do not influence the disposable dust remover dust removing effects; Can not cause substantial influence, also reduce the pressure-losses of gas flow, save power consumption the wearing and tearing and the heat exchange of boiler.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
Embodiment:
The utility model structure comprises vault 6, encloses frame body of wall 4, high temperature expansion joint 5, diffuse hole, ash bucket 3, water cooling sleeve pipe 2, ash-valve 1, it is characterized in that: enclose frame body of wall 4 inner chambers the dedusting baffle plate is not set.
Use according to reality and to draw the macrobead coke powder (diameter >=0.5mm) flow velocity reduces and two factors of parabolic motion before not getting into boiler; Just fall into ash bucket 3 by deadweight; Real operation has been verified the dedusting barricade and has not been had the not obviously difference of the actual dust separating ash amount of dedusting barricade, therefore there is no need to design disposable dust remover dedusting baffle plate again.
