High-temperature high-efficiency explosion-proof integrated modular dust removal equipment for pyrolysis raw coal gas

An explosion-proof integrated modular dust removal equipment for pyrolysis raw coal gas, the equipment comprising:

• a housing internally provided with a chamber that enables a medium to flow from a gas inlet of the housing to a gas outlet of the housing;
• a ceramic filter system, the ceramic filter system configured to divide the chamber of the housing into a dust collection chamber and a gas purification chamber that are separate, the ceramic filter system positioned in the dust collection chamber and configured to permit communication between the dust collection chamber and the gas purification chamber;
• a high-pressure backblow system, the high-pressure backblow system mounted in the gas purification chamber, and configured to perform a backblow operation towards the dust collection chamber;
• and
• a preliminary dust removal system, the preliminary dust removal system positioned outside the housing, and in communication with the dust collection chamber, the preliminary dust removal system comprising a preliminary dust remover and a cinder valve mounted at a bottom of the preliminary dust remover,
• wherein a gas inlet of the preliminary dust remover is in communication with a raw gas source, and a gas outlet of the preliminary dust remover is in communication with the dust collection chamber, and
• wherein an air cooler is mounted inside the preliminary dust remover, and a fan is mounted on the air cooler.
