Description

The ring grid theisen disintegrator

The utility model relates to a kind of separator, specifically a kind of deduster.

The deduster of present industrial usefulness is divided into four big classes substantially: (1) mechanical dust collector, and as inertial dust separator and cyclone dust collectors etc.(2) filtration dust catcher.(3) wet scrubber is as venturi scrubber etc.(4) electric cleaner.In the above-mentioned four big class dedusters,, exist easy to wear and shortcoming such as efficient is low though that traditional mechanical collector has is simple in structure, cost is low, advantage such as easy to maintenance; Though filtration dust catcher has very high efficient, its resistance is bigger, the operating cost height, and need often to change filter bag, maintenance cost is higher; Wet dust removal has higher efficient equally, but its floor space is big, energy consumption is high and can produce secondary sewage; Electric cleaner has the high characteristics of efficiency of dust collection equally, and energy consumption is lower, but its major defect is that the consumption steel are many, and floor space is big, the initial cost height.With the immediate background technology of the utility model be the mechanical type inertial dust separator.

The utility model purpose be to provide a kind of simple in structure, cost is low, easy to maintenance, have simultaneously high efficiency dedusting, floor space and requisite space circlet grid formula theisen disintegrator again.

The purpose of this utility model is achieved in that it comprises deduster body housing 1, be arranged at the ring grid 2 of deduster body housing inside, these ring grid are made up of one group of ring, along the diameter of airflow direction ring gradually change and encircle and encircle between have a fixed gap, there is dust flue 4 at deduster shell rear portion, connects dust arrester 5 under the dust flue, and dust exhaust 6 is arranged under the dust arrester, have backwind tube 8 on the dust arrester, have return air air-introduced machine or compressed air injector 9 on the backwind tube.

The utility model can also comprise following architectural feature:

1, the ring of makeup ring grid reduces gradually along the diameter of airflow direction ring, last ring of dust flue T-Ring grid.

2, the ring of makeup ring grid increases gradually along the diameter of airflow direction ring, and dust flue connects deduster shell rear portion.

3, the porch of backwind tube has dirt catcher.

4, there is kuppe in deduster import department.

Advantage of the present utility model is: the one, simple in structure, cost is low, easy to maintenance; The 2nd, efficiency of dust collection height, floor space and required space are little; The 3rd, can make up neatly, be applicable to various application occasions, and easy for installation.Device of the present utility model is compared with the mechanical cyclone dust collector of industrial extensive employing at present, and efficiency of dust collection can improve about 24%, and dust removal efficiency can reach more than 99%, and it is about 1/3 that its energy consumption reduces, and installation footprint reduces more than 40%.Dedusting or material that device of the present utility model can be widely used in the industries such as chemical industry, grain processing, timber processing, cement, electric power, metallurgy, boiler operatiopn reclaim.

Fig. 1 and Fig. 3 are the structural representations of two kinds of most preferred embodiments of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 4 is the B-B cutaway view of Fig. 3.

For example the utility model is done more detailed description below in conjunction with accompanying drawing:

Earlier in conjunction with Fig. 1 and Fig. 2.The composition of ring grid theisen disintegrator comprises deduster body housing 1, and the deduster enclosure has ring grid 2, and these ring grid are made up of one group of ring, along the diameter of airflow direction ring reduce gradually and encircle and encircle between a fixed gap is arranged, formation conical ring grid.Each ring is designed to specific blade shape according to the needs that improve separative efficiency, reduce aerodynamic drag.In order to improve the wearability of ring grid under some application scenario, the ring grid are adopted high-abrasive material or cure process is carried out on the ring grid surface that contacts with dust.There is kuppe 3 in deduster import department, and there is dust flue 4 at deduster shell rear portion, last ring of dust flue T-Ring grid.Connect dust arrester 5 under the dust flue.Dust exhaust 6 is arranged under the dust arrester.Have backwind tube 8 on the dust arrester.Have return air air-introduced machine or compressed air injector 9 on the backwind tube.The porch of backwind tube 8 has dirt catcher 7 in case of necessity.The course of work of the present utility model is described in detail in detail below: the air-flow that contains dust enters kuppe with certain speed by the deduster inlet, the inner loop of flowing through grid, dust granule reaches with the comprehensive function lower edge ring grid inwall that encircles the grid impact force at aerodynamic force, inertia force and moves to the ring grid vertex of a cone, finally enters dust arrester with a certain amount of gas by the dust flue that is connected in last ring of the vertex of a cone.Clean gas then flows to the outside of ring grid by the space between ring and the ring and is discharged by the deduster outlet.In dust arrester inside, most of dust sinks to the dust arrester bottom, is discharged by dust exhaust.When not establishing backwind tube inlet dirt catcher, other has small amount of dust to get back to the deduster inlet with gas through backwind tube and return air air-introduced machine or injector.When dirt catcher is set, can the backwind tube outlet be connected to deduster inlet or outlet according to actual conditions.

Again in conjunction with Fig. 3 and Fig. 4.This structure has better wear resistance than the structure described in the last example.The ring that the main distinction of it and last example is the makeup ring grid increases gradually along the diameter of airflow direction ring, and dust flue connects deduster body housing rear portion.Each ring in the ring grid has the good pneumatic profile identical with last example, and dust-contained airflow then flow to the awl end by the ring grid vertex of a cone along its outer surface.Because the dust concentration in dust one sidewind is constantly increased by inlet to outlet in deduster, thereby causes the ring grid in exit easily to be worn.And in the present embodiment, because dust export is the annulus area that shell and ring grid final stage ring are constituted, so wearability strengthens.The course of work of present embodiment is: the air-flow that contains dust is entered by the deduster inlet with certain speed, the inner loop of flowing through grid, increase gradually along airflow direction ring grid diameter, dust granule reaches with the comprehensive function lower edge ring grid outer wall of ring grid impact force at aerodynamic force, inertia force and bores end motion to the ring grid, finally enters dust arrester with a certain amount of gas by dust flue.Clean gas then flows to the inboard of ring grid through deduster outlet discharge by the space between ring and the ring.In dust arrester inside, most of dust sinks to the dust arrester bottom, is discharged by dust exhaust.When not establishing backwind tube inlet dirt catcher, other has small amount of dust to get back to the deduster inlet with gas through backwind tube and return air air-introduced machine or injector.When dirt catcher is set, can the backwind tube outlet be connected to deduster inlet or outlet according to actual conditions.

The deduster of the described two kinds of forms of above-mentioned two embodiment can carry out the serial or parallel connection combination by needs as the case may be, and combination in parallel can improve the dusty gas treating capacity, and tandem compound can improve efficiency of dust collection.
