Abstract
The utility model relates to an internal filtration type cloth bag type strainer with upper and lower air inlet, which comprises a box body, a raw gas leadin tube, a raw gas inlet tube, a cloth bag and a clothe bag box body. The utility model is characterized in that the lower part of the raw gas leadin tube is connected with the raw gas inlet tube, the outlets of the upper end and the lower end of the raw gas inlet tube face towards the upper cavity and the lower cavity of the box body, latticed plates which are welded on the upper part and the lower part of the box body are connected with the clothe bag, encircling tubes encircle the external of the box body and are communicated with pure gas tubes by supporting tubes, and pure gas is conveyed to a pure gas tube net to provide for users. The utility model can reduce the gas flow rate of the inlet end of the cloth bag and overcome the defect of local excessive temperature, and therefore, the service life of the cloth bag is increased by 2-3 times.
Description
The utility model relates to air inlet inward flow filtration-type bag-type dust collector up and down, and it is mainly used in the dedusting of blast furnace gas in the metallurgical production process, also can be used in the environmental protection dust collecting process of building material cement industry.
The inward flow filtration-type sack cleaner that existing dedusting of blast furnace gas device is the air inlet of a kind of lower end, raw coke oven gas is entered by cloth bag one end, the flow velocity height, the cloth bag arrival end is produced powerful scouring force, 2 meters long section local pressures of cloth bag arrival end are big, are torn easily, and the life-span is short, generally can only use about half a year, and ring shadow gas purification quality of stability.
The purpose of this utility model provides that a kind of it can reduce cloth bag arrival end gas speed, overcomes the too high defective of local temperature by the inward flow filtration-type bag-type dust collector of two ends air inlet up and down, thereby improves cloth bag service life.
The utility model is the improvement to existing lower end air inlet inward flow filtration-type sack cleaner, its structure mainly contains casing 10 as shown in drawings, raw coke oven gas inlet tube 9, raw coke oven gas inlet pipe 4, bustle pipe 5, clean coal tracheae 6, cloth bag 8, cloth bag casing 11, wherein raw coke oven gas inlet tube 9 is connected with the bottom of raw coke oven gas inlet pipe 4, and the outlet at these coal gas inlet pipe two ends about in the of 4 is facing to the cavity up and down of casing 10, and raw coke oven gas inlet pipe 4 can be contained in the casing 10 or be contained in casing 10 outsides, be welded with lattice board 3 in the casing upper and lower, lattice board 3 is connected with cloth bag 8 up and down, and its connection is to connect with the taper bolt of being with cavity, and bustle pipe 5 is trapped among casing 10 outsides and is communicated with cloth bag casing 11 by arm, bustle pipe 5 is connected with clean coal tracheae 6, and clean coal tracheae 6 sides are connected to anti-blowpipe 7 purified gas blowback remaining in the clean coal tracheae is gone in the cloth bag 8.
The operating principle of this dust arrester is: raw coke oven gas enters raw coke oven gas inlet pipe 4 by inlet tube 9, entering up and down from the outlet of the two ends up and down of this inlet pipe, cavity enters cloth bag 8 again, purified gas behind the cloth bag filtration enters cloth bag casing 11, enter clean coal tracheae 6 via bustle pipe 5, enter the purified gas pipe network again and use for the user; When stopping to supply gas, anti-blowpipe 7 is gone into remaining purified gas blowback in the clean coal tracheae 6 in the cloth bag 8.
The utility model its advantage compared with the prior art is:
1. adopt two ends air inlet up and down, cloth bag porch air velocity is reduced, thereby reduce impulsive force, improve cloth bag 2-3 in service life doubly cloth bag;
2. because two ends air inlet up and down wherein has semi-coal gas stream to be entered by suitable for reading, make the consistent buoyancy that reduces coal gas stream to dust of coal gas flow path direction, realized gravitational effect, help the sedimentation of dust, improved the gas permeability of cloth bag with the ash fall direction;
Since up and down the two ends air inlet make along the cloth bag axial load and be evenly distributed, improved the effective rate of utilization of cloth bag;
4. because the load of single devices improves, when handling equivalent coal gas, the cloth bag casing can reduce.
Description of drawings:
Accompanying drawing is an air inlet inward flow filtration-type bag-type dust collector structural representation up and down
Below in conjunction with accompanying drawing each parts of the utility model being installed connection is described further:
The purified gas exhaust stack 1 of this dust arrester is installed on the lattice board 3, raw coke oven gas exhaust stack 2 is installed in casing 10 tops and communicates with cavity, lattice board 3 is welded on the casing upper and lower, it is inner or outside that raw coke oven gas inlet pipe 4 is installed in casing 10, bustle pipe 5 is trapped among the casing outside and is communicated with cloth bag casing 11 by arm, bustle pipe 5 is connected with clean coal tracheae 6, the clean coal tracheae 6 other anti-blowpipes 7 that connect, lattice board 3 is connected with cloth bag 8 up and down, cloth bag 8 adopts the alkali-free glass fibre filter cloth to make, raw coke oven gas inlet tube 9 is connected with raw coke oven gas inlet pipe 4, is provided with cleaning door 12 in casing 10 lower ends.
