Self-cleaning high-flow gas filtering apparatus

Abstract

The invention relates to a self-cleaning high-flow gas filtering apparatus. The invention comprises a gas filter body and is characterized in that: one end of the gas filter body is provided with a gas inlet, and the other end of the gas filter body is provided with a gas outlet; wind guiding devices are provided at the gas inlet and the gas outlet; the filtering apparatus is provided in the gas filter body, the top of the filtering apparatus is provided with a filter screen out-taking opening, the bottom of the filtering apparatus is provided with a sewage draining exit, one side of the filtering apparatus is provided with an automatic spraying and flushing means which is connected with a differential pressure display instrument arranged out of the gas filter body. The advantages of the invention are as follows: the service life of a filter screen is prolonged; filtering efficiency is improved, the service life of a filter core is prolonged, and the backwashing cycle of the filter core is increased; the whole process is automatically carried out through program control, needing no manpower and being time-saving and labor-saving.

Description

technical field [0001] The invention relates to a gas filter device, in particular to a self-cleaning large-flow gas filter device. Background technique [0002] The gas filter is an important equipment in the gas transmission and distribution system. In the process of gas transmission and distribution, in order to ensure the normal operation of equipment and instruments such as pressure regulators and other valves, flow meters, pressure gauges and other instruments and protect them from damage, it must To remove solid impurities in the gas, a suitable filter must be installed before it. The existing gas filter uses a stainless steel wire mesh filter element, which has a small gas processing capacity, the filter is easy to block, difficult to clean, and the assembly and disassembly of the filter cartridge is time-consuming and laborious. , equipment resistance and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to provide a s...
