Abstract

The utility model discloses a bag-type dust remover. The bag-type dust remover comprises an access door, a net gas chamber and dust gas chambers, wherein a dust gas inlet is formed in the diameter of an air inlet of a lower box dust hopper part of the dust remover; a circular-arc shaped dust baffle plate is arranged above a position at which dust gas passes through the dust hopper; the dust baffle plate is as long as the air inlet of the dust remover; the circular-arc diameter of the dust baffle plate is equal to the diameter of the air inlet; and the height of the dust baffle plate is 1/3 of the diameter dimension of the air inlet. According to the bag-type dust remover provided by the utility model, the circular-arc dust baffle plate is designed at the dust gas inlet of the dust remover, so that large dust-containing particles are affected by gravity to drop into the dust hopper due to inertia and collision of the dust baffle plate when the dust-containing air enters the bag-type dust remover. Small dust particles enter a bag-type filter region, and are filtered by the bag-type dust remover. The filtering burden of the filter bag is greatly relieved; the dust removing efficiency is improved; and the change period and the service life of the filter bag are prolonged.

Description

Bag filter

technical field

The utility model relates to a bag filter. the

Background technique

The pulse bag filter is a kind of high-efficiency dust removal equipment that uses a filter bag made of organic fiber or inorganic fiber cloth to filter the dust in the dusty gas. The dust removal efficiency is high, generally up to 99%. The main component of the bag filter is the filter cloth or filter bag. Due to the different working environment, the filter bag needs to be replaced regularly to ensure the dust removal efficiency of the equipment. Therefore, the service life of the filter bag is the key to the dust removal efficiency and overall life of the dust collector. the

At present, the pulse dust removal equipment commonly used in domestic ventilation and dust removal, the traditional method is that the dust gas enters the dust collector body from the dust gas inlet of the dust collector and then directly enters the filter bag filter area. the

The bag filter belongs to the medium and high efficiency filter, and the dust particle size captured is between 0.5-15 μm, while the dust at the entrance of the general dust collector has a particle size distribution within a large range, and the dust particle size is greater than 20 μm. Directly entering the bag filter area will cause the following adverse consequences: 1) After the dust collector has been working for a period of time, the wear degree of the filter bag near the dust gas inlet is far greater than that of other filter bags; 2) Large particles of dust directly enter the bag filter In this area, the filter burden of the filter bag is increased, the dust removal efficiency is reduced, and the replacement cycle and life of the filter bag are shortened. the

Contents of the invention

The purpose of this utility model is to provide a bag filter, which can greatly extend the replacement cycle and life of the filter bag. The purpose of this utility model is achieved in this way. The bag dust collector includes an inspection door, a clean air chamber, and a dust air chamber. An arc-shaped ash baffle is arranged above the ash hopper where the dust gas passes; the length of the ash baffle is equal to the length of the air inlet of the dust collector, the diameter of the arc of the ash baffle is equal to the diameter of the air inlet, and the height of the ash baffle is 1/3 of the diameter of the air inlet. The utility model designs a circular arc-shaped ash baffle at the dust gas inlet of the dust collector. When the dusty air enters the bag filter, large dust particles will sink due to inertia and collision with the ash baffle. , into the ash hopper. The air containing smaller particles of dust enters the bag filter area and is filtered by the bag filter. It greatly reduces the filtering burden of the filter bag, improves the dust removal efficiency, and prolongs the replacement cycle and life of the filter bag. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described;

The bag dust collector includes an inspection door 3, a clean air chamber 4, and a dust chamber 7. It is characterized in that: the dust gas inlet is located at the diameter of the air inlet of the ash hopper 9 of the lower box of the dust collector equipment, and the ash hopper where the dust gas passes An arc-shaped gray baffle is arranged above; the length of the gray baffle 8 is equal to the length of the air inlet of the dust collector, the arc diameter of the ash baffle 8 is equal to the diameter of the air inlet, and the height of the ash baffle 8 is the diameter of the air inlet. 1/3 of the size. In specific implementation, as shown in the figure, the dust gas inlet of the pulse dust collector is located at the diameter of the air inlet of the dust hopper part of the lower box of the dust collector equipment, and the direction of the arrow in the figure indicates the airflow direction in the box. Under the action of the induced draft fan, the dust-laden gas enters from the dust gas inlet, and first passes through the ash baffle, and the large dust particles sink under the influence of gravity due to inertia and collision with the ash baffle, and fall directly into the ash hopper ;The dust with smaller particles bypasses the gray baffle and is filtered by the filter bag, and the clean gas passes through the filter bag to the inside of the filter bag and is taken out of the box by the induced draft fan to achieve the purpose of filtering the dusty gas. the

Claims (2)

1. sack cleaner, comprise access door (3), air-purifying chamber (4), dirt air chamber (7), it is characterized in that: dirt gas entrance is positioned at the air inlet diameter place of deduster equipment lower box ash bucket (9) part, is provided with circular arc dust block board (8) at dirt gas through the top of locating ash bucket (9).

2. sack cleaner according to claim 1, it is characterized in that: described dust block board (8) length and deduster air inlet equal in length, dust block board (8) arc diameter and air inlet equal diameters, the height of dust block board (8) is 1/3 of air inlet diameter dimension.
