Dust removal equipment

Abstract

The invention discloses dust removal equipment, comprising a shell (1), a filter element (2) and an exhaust pipeline (3), wherein the shell (1) is provided with an air inlet (13) and an exhaust opening; the filter element (2) is positioned in the shell (1); an air inlet shunt cavity is formed between the filter element (2) and the shell (1), and the air inlet (13) is formed in one side of the bottom of the shell (1) and below the filter element (2) in the longitudinal height; the air inlet end of the exhaust pipeline (3) is positioned at an exhaust current collecting cavity of the filter element (2), and the air outlet end of the exhaust pipeline (3) is led outwards from the lower part of the filter element (2) to form the exhaust opening. According to the dust removal equipment, the filter burden of the dust removal filter element can be significantly reduced, the dust removal filter effect can be enhanced; the cleaning cycle of the dust removal equipment can be effectively prolonged under the condition that the same filter requirement is met, so that the production cost and the cleaning and maintenance cost of the filter element are reduced.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to dust removal equipment for filtering waste gas in industrial production processes. Background technique [0002] Dust removal equipment is commonly used in industrial production. There are many production devices that need to install dust removal equipment at the air inlet and outlet in order to filter the incoming air to ensure the cleanliness of the inside of the equipment, and to filter the exhaust gas to ensure the discharge The gas does not pollute the atmosphere, and the dust filter element of the dust removal equipment, like the filter layer of the mask, needs to be cleaned on time to ensure its filtering effect. [0003] Although the existing dust removal equipment can meet the requirements of use to a certain extent, there are still deficiencies. For example, the single crystal furnace, which is the production equipment of monocrystalline silicon, has the following ...

Problems solved by technology

[0006] Thirdly, because it is impossible to pre-treat the impurities in the gas, it relies entirely on the filter element for filtration, which greatly increases the workload of the dust removal filter element. During the production process, the dust removal filter element needs to be cleaned in time, and the cleaning of the filter element is too frequent. The large amount will affect the preparation time of the single crystal furnace equipment. At the same time, it is easy to cause damage to the surface of the filter element, affecting the service life of the filter element, and the investment cost is high. Moreover, the filter element is not easy to be cleaned. Product quality, in addition, because impurities containing particles are easily inhaled into the body, employees engaged in this work are prone to occupational diseases
