Powder tank pressure release dust remover and dust removal system

The invention relates to the field of tank body dust removal and discloses a powder tank pressure release dust remover and a dust removal system. The dust remover comprises a rainproof cover, a box body, multiple support keels and multiple dust removal cloth bags; the dust removal system comprises a powder tank, a feed pipe and a powder tank energy-saving dust remover; through structural optimization, the dust remover is arranged above the powder tank; after the powder conveyed by the feed pipe enters the powder tank, the powder tank is filled with the air-powder mixture and stays in a positive-pressure state; the flying dust can drop into the powder tank through natural settling while some dust ascending with the positive pressure enters the dust removal cloth bag and stays in the cloth bag under the effects of adhesion and electrostatic adsorption; the remaining positive pressure is released from around the box body through the rainproof cover; thus, a natural and energy-saving dustremoval effect is realize
