Description

Technical Field

[0002] The raw gas filter is an important equipment in the coal gas and coal tar production device, which is mainly used to filter and remove impurities and coal tar in the coal gas. This equipment usually includes a large filter tank with multiple layers of filter screens or filter cartridges inside, which can effectively remove solid particles and liquid droplets in the coal gas. In order to better filter and treat the raw gas during the coal gas and coal tar production process and avoid pollution to the environment, a raw gas filter for the coal gas and coal tar production device is needed.

[0003] After searching, a raw gas filter for a coal gas and coal tar production device disclosed in Chinese patent publication No. CN202105534U adopts a low-pressure difference and high-temperature resistant ceramic filter tube under normal pressure, which can directly filter and remove dust above the dew point at normal pressure and high temperature, and be used for high-temperature gas backblowing to prevent oil and gas from condensing on the ceramic tube and clogging the filter holes. It has the advantages of small pressure difference, high filtration efficiency, automatic backblowing, and long service life. It can be used as a filter for coal gas and coal tar production devices.

[0004] However, the above patent has certain shortcomings in actual use.
