Abstract

The utility model discloses a bag type dust recovery unit. A left lower tank body and a right lower tank body are parallelly arranged on an upright post, the lower portions of the lower tank bodies are connected with a dust hopper, small-bore filter bags are thickly arranged inside the lower tank bodies, the upper portions of the lower tank bodies are connected with corresponding left and right upper tank bodies via lattice panels, blowing pipes on an impulse blowing device are placed inside the left upper tank body and the right upper tank body, an air inlet pipe is arranged on the left lower tank body, and an air outlet pipe is arranged on the right upper tank body. The bag type dust recovery unit resolves the problem that the prior art is limited by length-diameter ratio, can increase filtering areas of the filter bags to the utmost extend under the condition that the area of a dust removing tank body is not changed, and has the advantages of long service life, fine dust removing effect, convenient and fast control and low cost.

Description

The pocket type device for recovering powder

One, technical field:

The utility model relates to the treating flour dust and the material retracting device of industries such as metallurgy, building materials, electric power, chemical industry, flue gas ash removal, is specifically related to the pocket type device for recovering powder.

Two, background technology:

Now, pulse bag type dust collector is because its distinctive pulse jet characteristics, be subjected to the restriction of draw ratio, the length of filtrate generally is no more than 8 meters, keep certain processing air quantity, needs to increase the cross-sectional area of dust-removing box, therefore dust pelletizing system has characteristics such as floor space is big, equipment investment cost height, its application has been subjected to certain restriction and restriction, especially because of produce needing, old deduster is carried out that the expansion scale is transformed and newly-built dust pelletizing system and place situation at full stretch.

Three, summary of the invention:

It is a kind of under the constant situation of dust-removing box area that the purpose of this utility model is to provide, and can increase the filter area of filter bag to greatest extent, and the pocket type device for recovering powder that ash-removal effect is good, cost is low.

For achieving the above object, pocket type device for recovering powder of the present utility model comprises column, left and right two lower boxes are installed on this column side by side, the lower box below is connected with ash bucket, the small-bore filter bag of solid matter in the lower box, the lower box top is through lattice board and corresponding left and right upper box connection, and the winding-up pipe on the pulse spraying equipment places in the left and right upper box, the lower-left casing is provided with blast pipe, and upper right casing is provided with discharge pipe.

Because technique scheme adopts small-bore filter bag solid matter and multistage pulse jetting deashing structure, therefore, under the constant situation of dust-removing box area, can increase the filter area of filter bag to greatest extent, and then improve the processing air quantity of dust pelletizing system; The use of multistage pulse jet technology is broken the normal procedure pulse bag type dust collector to the restriction of draw ratio, and the winding-up pipe gos deep into filter bag inside and carries out the multistage winding-up, and ash-removal effect is good; Compare with traditional sack cleaner, dust-precipitator, the utility model adopts two-stage cloth bag filtration system, has following main feature:

1, material recovery rate height, collecting effect significantly improve, and have greatly reduced the loss of material, and the recycling of important material is had remarkable economic efficiency.

2, because the employing two-stage filtration system is carried out the flue gas processing, good dedusting effect, smoke emissioning concentration is low.

3, filtration velocity is low, and life of bag filter is long.

4, ash-removal effect is good, controls convenient and swift.

5, cost of investment is low, and the plant maintenance workload is few.

Four, description of drawings:

Fig. 1 is the structural representation of the utility model pocket type device for recovering powder;

Fig. 2 is the structural representation of the another kind of embodiment of the utility model.

Five, the specific embodiment:

As seen from Figure 1, pocket type device for recovering powder of the present utility model comprises

column

14,11, two lower box belows of lower-left casing 2 and bottom right casing is installed on this column 14 side by side is connected with ash bucket 13, and ash-discharging device 15 is installed in the outlet of ash bucket 13.In two lower boxes all 12, two lower boxes tops of the small-bore filter bag of solid matter be connected with upper right casing 9 with corresponding upper left casing 4 through lattice board 5.9 of upper left casing 4 and upper right casings have dividing plate 7 to be separated by, and top access door 6 is all established on top.Winding-up pipe 8 on the pulse spraying equipment 3 places in the left and right upper box, and lower-left casing 2 is provided with blast pipe 1, and upper right casing 9 is provided with discharge pipe 10.

Operation principle of the present utility model is: dusty gas enters lower-left casing 2 by blast pipe 1, see through behind the filter bag 12 through filtering for the first time, enter upper left casing 4, bottom right casing 11 then, the beginning secondary filter, after filtering, air communication filter bag 12 enters upper right casing 9, discharge through discharge pipe 10 then, filter and finish.Through filtering constantly carrying out of operating mode, dust or material on the filter bag are cumulative, and equipment resistance increases, need carry out deashing, pulse spraying equipment 3 starts, and carries out pulse jetting deashing by 8 pairs of filter bags 12 of winding-up pipe, dust or the material shaken off drop in the ash bucket 13, transport by ash-discharging device 15.

Fig. 2 is an another kind of version of the present utility model.According to equipment filter area and structure, two ash buckets 13 can be set.Also can establish a plurality of ash buckets.
