Vacuum filter

Abstract

The invention discloses a vacuum filter, and belongs to the field of filtration, which is used for solving the problems of cooling and dedusting of high-temperature and dust-contained gas in a vacuum working system. The vacuum filter comprises a cavity body, a diffuser and a filter element, wherein the cavity body is provided with a gas inlet connected with a specific gas pipeline and a gas outlet connected with a vacuum pump; the top end of the cavity body is provided with a top cover connected with the cavity body in a sealed mode; the cavity body is internally provided with the diffuser at the gas inlet; the filter element is installed at the center in the cavity body; the side wall of the filter element is provided with filter holes; the bottom surface of the filter element is provided with an opening leading to the gas outlet of the cavity body, thereby preventing the vacuum pump and an upstream-downstream system from being damaged by high-temperature, corrosive and dangerous dust particles, and solving the problem of too complex and frequent maintaining frequency of the vacuum pump of the vacuum filtration system. From the aspect of environment protection, gas in pipelines can be further cooled down and purified, and air pollution can be reduced.

Description

technical field [0001] The invention relates to a filter, in particular to a vacuum filter. Background technique [0002] In photovoltaic solar energy and some other industries, specific process gases are usually used. These process gases have a high temperature and often contain dust, especially the dust is corrosive or harmful, which not only damages the vacuum pump and the flow of the gas Pipeline, and discharge into the atmosphere will also bring environmental pollution. Contents of the invention [0003] In order to solve the above problems, the present invention provides a vacuum filter capable of filtering a specific process gas and ensuring that the specific process gas operates in a vacuum environment. [0004] The vacuum filter of the present invention includes a cavity, a flow uniform plate and a filter element, wherein the cavity is provided with an air inlet connected to a specific gas pipeline and an air outlet connected with a vacuum pump, and the top of th...
