Description

A high-efficiency filter bag filter

technical field

The utility model belongs to the technical field of dust removal equipment, in particular to a high-efficiency filter cloth bag dust collector.

Background technique

In tobacco, metallurgy, mining, cement and other manufacturing industries, dust collectors for purifying gases are needed, and bag dust collectors are more commonly used. It includes a filter chamber, an ash hopper, a filter bag, an air inlet pipe and an air outlet pipe. The filter bag is fixed in the filter chamber, the ash hopper is located under the filter chamber, and the air inlet pipe and the air outlet pipe are respectively fixed on both sides of the filter chamber. When in use, after the gas enters the filter chamber of the dust collector, due to the effect of gravity, some relatively large dust in the gas directly falls into the ash hopper below the filter chamber, and the rest of the dust is purified through the filter bag in the filter chamber. However, the current bag filter generally has the following defects: the flue gas flow in the dust removal chamber is not uniform, which affects the purification effect of the gas.

Utility model content

The utility model provides a high-efficiency filter bag dust collector to solve the problem that the air flow in the dust removal chamber of the existing bag dust collector is not uniform during use, thereby affecting the gas purification effect.

The technical purpose of the utility model is achieved through the following technical solutions: a high-efficiency filter bag filter, including a dust removal chamber, a dust removal hopper is installed at the bottom of the dust removal chamber, and an ash outlet pipe is installed on the dust removal hopper. On-off valves are installed on the ash outlet pipe, multiple filter frames are installed inside the dust removal chamber, filter bags are laid on the surface of the filter frames, and a venturi tube is installed on the top of each filter bag. A plurality of blowing pipes located above the filter bag are installed inside the dust removal chamber. One side of the dust removal chamber is connected with an air intake pipe, and the other side of the dust removal chamber is equipped with an exhaust pipe. fan.

The principle and effect of the technology: through the venturi tube arranged under the blowing pipe, the gas velocity above the filter bag is made consistent, so that each filter bag produces a consistent suction, so that the airflow inside the dust removal chamber is more uniform, thereby increasing the purification effect.

Further, a ladder is installed on the side wall of the dust removal chamber, and guardrails are installed around the top of the dust removal chamber.

With the above scheme, the operator can enter the top of the dust removal chamber through the ladder when replacing the filter bag.

Further, a plurality of top covers are installed on the top of the dust removal chamber, and the top covers are bolted to the dust removal chamber.

By adopting the above scheme, it is convenient for the operator to open the dust removal chamber.

Further, the exhaust pipe is located above all filter bags.

By adopting the above scheme, it is convenient to discharge the purified gas.

Further, a plurality of support frames are installed on the bottom of the dust removal chamber, and a plurality of reinforcing bars are installed between the support frames and the dust removal bucket.

By adopting the above solution, the stability between the dust removal bucket and the supporting frame can be increased.

Compared with the prior art, the beneficial effect of the utility model is: it can make the suction generated above each filter bag consistent, so that the airflow above the dust chamber can evenly flow to the exhaust pipe, so that the air filtered on each filter bag The amount of dust is not much different, so that the service life of each filter bag is not much different.

Detailed ways

Further detailed description will be given below through specific embodiments.

Embodiment: As shown in Figure 1 to Figure 2, a high-efficiency filter bag filter, including a dust removal chamber 1, the bottom of the dust removal chamber 1 is welded with a dust removal hopper 2, the dust removal hopper 2 is used to collect dust, and the bottom of the dust removal hopper 2 is connected There is an ash outlet pipe 3, and an on-off valve 4 is installed on the ash outlet pipe 3, and the dust collected in the dust hopper 2 can be released by opening the on-off valve 4. The side wall of the dust removal chamber 1 is bolted with a ladder 5, and the top of the dust removal chamber 1 is bolted with a plurality of top covers 7, and guardrails 6 are also installed around the top of the dust removal chamber 1. The bottom of the dust removal chamber 1 is welded with four support frames 8, and a plurality of reinforcement bars 9 are welded between the support frame 8 and the dust removal hopper 2, and the reinforcement bars 9 can increase the stability of the dust removal hopper 2. A plurality of filter frames arranged at intervals are installed inside the dust removal chamber 1 , the filter frames are in the shape of a test tube as a whole, and filter bags 10 are laid on the surfaces of all the filter frames. The top of each row of filter bags 10 is equipped with a blowing pipe 12 , and the top of each filter bag 10 is equipped with a venturi tube 11 . One side of the dust removal chamber 1 is equipped with an air inlet pipe positioned at the bottom of the filter bag 10, and the other side of the dust removal chamber 1 is equipped with an exhaust pipe 13 positioned at the top of the filter bag 10, and a blower fan 14 is also installed on the exhaust pipe 13 for The purified gas is discharged.

When working, the dust-containing gas enters the dust-removing chamber 1 from the exhaust pipe 13, and then the blowing pipe 12 is opened, the pressure above the filter bag 10 is lower than the pressure below the filter bag 10, so the dust-containing gas will flow from the bottom of the dust-removing chamber 1 to Movement above the dust chamber 1. At this time, the dust-laden gas contacts the filter bag 10 , the dust is filtered by the filter bag 10 and stays on the surface, and the filtered gas reaches the top of the filter bag 10 and is then discharged by the exhaust pipe 13 . And there is a blowing pipe 12 above each row of filter bags 10, so that the gas flow rate above all filter bags 10 is uniform, and the air flow in the dust removal chamber 1 is then more uniform like this.
