Embodiment Construction

[0026] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0027] like figure 1 As shown, the dust-laden gas enters from the dust collector inlet 1. After passing through the inlet, the horizontally flowing gas becomes a rotating gas in the cone 4, and it will rotate around the side wall of the dust collector and move downward. Under the action of centrifugal force, the gas The large particles in the gas will be separated and fall into the ash hopper 5; the setting of the cone can effectively reduce the abrasive impact of the particles in the gas on the air tube 11 and the filter bag 12. The particles that cannot be separated will continue to move with the gas, and the gas will continue to move to the center and the lower end of the cone 4 at the same time, and when the gas reaches the lower end of the cone 4, it will turn and move upward to become an internal spiral gas. The inner swirling gas rotates upwards from th...

Abstract

The invention relates to a bag type dust collector. The bag type dust collector comprises a dust collector inlet (1), a dust collector outlet (13), a gas distributing plate (6), a gas filling plate upper board (8), a gas filling plate lower board (9), a gas filling head (10), a plurality of gas filling tubes (11) and a filter bag (12). The gas filling tubes (11) with equal length are connected to a gas filling opening (21) in a sealing mode, so that the uniformly-distributed gas filling tubes (11) form a bag cage; the filter bag sleeves the bag cage. The bag type dust collector is simple in structure, the impact effect of pulse-gas dust collection to the filter bag in the prior art is avoided, and the service life of the filter bag is prolonged.

Description

technical field [0001] The invention relates to a gas dust removal device. In particular, the invention relates to a bag filter. Background technique [0002] Bag filter is widely used to purify dusty gas produced in metallurgy, mining, chemical industry, cement, power generation, grain processing and other industries. The working principle of the bag filter is to introduce the dust-laden gas into the filter bag and let it pass through the filter bag in the filter bag, and the dust particles will be intercepted and left on the surface of the filter bag to form a dust layer. The clean air passes through the filter bag and then exits the dust collector. [0003] After running for a period of time, the dust layer accumulated on the dust-facing surface of the bag filter bag becomes thicker and thicker, which increases the resistance loss of the dust collector and seriously affects the dust removal efficiency of the dust collector. Therefore, after the bag filter has been runn...
