Abstract
The invention discloses a double-inlet turbulence mixing type bag dust remover and a dust removing method thereof. The dust removing method of the double-inlet turbulence mixing type bag dust remover is as follows: dust-containing air flow is divided into two ways to respectively enter both sides of a dust hopper of the dust remover, the two ways of inlet air flows directly oppositely rush and impact in the dust hopper to form intense turbulences, and partial dust granules are separated from air under the action of the impact and the turbulences and then fall into the dust hopper so as to effectively reduce the filtering load of a filtering bag and optimize the uniformity of a flow field in the dust remover. The double-inlet turbulence mixing type bag dust remover which employs the dust removing method above comprises an upper box body, a middle box body and the dust hopper, wherein the middle box body is internally provided with the filtering bag for filtration, both sides of the middle box body are respectively provided with one path of air inlet and outlet total pipe, wherein the two paths of air inlet and outlet total pipes are internally provided with air duct partition plates for distinguishing air inlet total pipes and air outlet total pipes, the two paths of air inlet and outlet total pipes are respectively connected with the dust hopper through two paths of air inlet pipelines, and the two air inlet pipelines are opposite just at both sides of the dust hopper. The double-inlet turbulence mixing type bag dust remover has simple structure, little running resistance and low energy consumption.
Description
Affiliated technical field
The present invention relates to a kind of fiber bag precipitator and dust collection method thereof, particularly a kind of double-inlet turbulence mixing type bag dust remover and dust collection method thereof.
Background technology
At present, sack cleaner is a kind of equipment that relies on fine particle thing in the filter bag filtration separation bubble, handles back airflow dust concentration and can reach 20mg/m
3Even lower, be widely used in industries such as building materials, metallurgy, power, mining industry and chemical industry.The general air intake mode that adopts unidirectional air intake to add deflector of existing deduster, its operation principle is, under the air-introduced machine effect, dust-contained airflow enters sack cleaner, after running foul of each other, the small part bulky grain directly falls into ash bucket in air-flow, most of dust is adsorbed on the filter bag with air motion, and from the filter bag discharge is clean gas.Be adsorbed on the filter bag dust can with dust-contained airflow constantly by increasing, make resistance of the filter bag rising gas permeability variation, for the strainability that makes filter bag recovers, need carry out deashing to filter bag.The general at present purge mode that adopts the back draught winding-up, and for the disposal ability that increases sack cleaner and save manufactured materials, can in higher filtration velocity and less casing volume, carry out integrated optimization during general design, but the problem of bringing thus is: wind speed is too high in the intake stack, formation is washed away to filter bag, reduces life-span of the filter bag; Air velocity distribution skewness in the deduster makes the filtration load of diverse location filter bag in the casing have very big-difference.For fear of said circumstances, usually set up deflector with special construction at the inner air inlet of deduster place, reduce the speed of dust-contained airflow, also can make the large particulate matter bump deflector in the flue dust lose inertia and fall into ash bucket, thereby realize the uniform and dust-contained airflow preliminary treatment in flow field.But also there is technological deficiency in such air intake design, and subject matter is: the air intake deflector adopts the mode of baffling, baffle to change the flow velocity and the flow direction of air-flow more, but the cost of paying is the running resistance that has increased deduster, and then has increased the energy consumption of air-introduced machine; Mounting guiding board has increased the complexity of deduster structure, has improved manufacturing cost; If deflector is installed overstocked or unreasonable structure, though can play the effect of water conservancy diversion, dust falls into ash bucket in the time of can hindering filter bag ash removal, and dust is bondd on deflector, is unfavorable for the long-term stability operation of deduster.
Summary of the invention
Technical problem to be solved by this invention is: a kind of double-inlet turbulence mixing type bag dust remover and dust collection method thereof are provided, utilize the collision that in ash bucket, directly liquidates of two-way air intake air-flow, form strong turbulent flow, reach the uniform effect in dust-contained airflow preliminary treatment and flow field simultaneously, improved the purification efficiency and the service life of filter bag; And its deduster is simple in structure, running resistance is little, energy consumption is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dust collection method of double-inlet turbulence mixing type bag dust remover, ash-laden gas flow point two-way is entered by the dust collector ash hopper both sides respectively, the collision that in ash bucket, directly liquidates of two-way air intake air-flow, form strong turbulent flow, the part dust granules is the ash bucket that falls into separated from the gas under bump and turbulent flow, thereby effectively reduce the filtration load of filter bag, optimize the uniformity of deduster flow field.
A kind of double-inlet turbulence mixing type bag dust remover of implementing above-mentioned dust collection method, comprise that the casing of deduster, described casing comprise upper box, middle casing and ash bucket, described upper box is provided with air stream outlet, install in the casing to filter in described and use filter bag, described ash bucket bottom is provided with cinder-discharging port, and whole deduster has support, and described middle casing both sides respectively are provided with one tunnel outlet and inlet house steward, be provided with the air channel dividing plate in the described two-way outlet and inlet house steward, to distinguish air intake house steward and air-out house steward; Described two-way outlet and inlet house steward is connected with ash bucket by the two-way intake stack respectively, and described two-way intake stack is connected to ash bucket both sides and relatively positive.
As further improvement, described ash bucket adopts the twin-bucket form, and the middle intersection point of two headwall plates is lower than the ash bucket intake stack.
The invention has the beneficial effects as follows: establish two-way outlet and inlet house steward in middle casing both sides, make the collision that in ash bucket, directly liquidates of two-way air intake air-flow, form strong turbulent flow, make dust-contained airflow deceleration in the casing, the flow field that reaches lower resistance, low energy consumption is uniform, and the bulky grain thing fully directly falls into ash bucket after the bump deceleration mutually in the dust-contained airflow, also reduced the load that filter bag filters, the purification efficiency and the clean-up effect of sack cleaner have effectively been improved, prolonged service life, and deduster is simple in structure, and running resistance is little, has reduced energy consumption.
