Description

A kind of double-inlet turbulence mixing type bag dust remover
Affiliated technical field
The utility model relates to a kind of sack cleaner, particularly a kind of double-inlet turbulence mixing type bag dust remover.
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.
The utility model content
Technical problem to be solved in the utility model is: a kind of double-inlet turbulence mixing type bag dust remover is provided, simple in structure, running resistance is little, energy consumption is low, reached the uniform effect of dust-contained airflow preliminary treatment and flow field simultaneously, the purification efficiency and the service life of having improved filter bag.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of double-inlet turbulence mixing type bag dust remover, 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, whole deduster has support, the casing both sides respectively are provided with one tunnel outlet and inlet house steward in described, 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 beneficial effects of the utility model are: 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.

Below in conjunction with accompanying drawing the utility model is described further:
The specific embodiment
Shown in each figure, a kind of double-inlet turbulence mixing type bag dust remover, the casing, the casing that comprise deduster are connected to form successively by upper box 2, middle casing 3 and ash bucket 4, on upper box 2, be provided with air stream outlet 6, the filter bag 7 that filters usefulness is installed in middle casing 3, respectively be provided with one tunnel outlet and inlet house steward 8 in the both sides of middle casing 3, in two-way outlet and inlet house steward 8, be provided with air channel dividing plate 10, so that distinguish air intake house steward and air-out house steward; Two-way outlet and inlet house steward 8 is connected with ash bucket 4 by two-way intake stack 5 respectively, and two-way intake stack 5 is positive positioned opposite on ash bucket 4; Ash bucket 4 adopts the twin-bucket forms, is provided with cinder-discharging port 9 in ash bucket 4 bottoms, and the middle intersection point of two headwall plates is lower than ash bucket intake stack 5, can allow the collision that directly liquidates in ash bucket of two-way air intake air-flow.Whole deduster has support 1, is used to support the deduster casing.
In use, dust-contained airflow enters sack cleaner from the air intake house steward of both sides, be assigned in the ash bucket 4 via intake stack 5 then, when twice dust-contained airflow when directly the front liquidates in ash bucket 4, promptly produced turbulence effects, make dust-contained airflow deceleration in the casing, reach the uniform effect in flow field, and the bulky grain thing fully directly falls into ash bucket after the bump deceleration mutually in the dust-contained airflow, casing 3 during all the other dust then rise to air-flow, filtered by filter bag 7, the clean gas after the filtration then enters the air-out house steward via the air stream outlet on the upper box 26 and discharges, and finishes filtration.After using certain hour, filter bag 6 is carried out deashing to keep its strainability, the dust that deashing obtains then falls into ash bucket 4, discharges from cinder-discharging port 9.
