Embodiment Construction
[0009] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0010] like figure 1 As shown, the arrangement structure of the bag filter in the bag filter includes: a housing 1, an ash hopper 7 is arranged at the lower end of the housing 1, a flue gas inlet 2 is arranged at the front end of the housing 1, and a smoke inlet 2 is arranged at the rear of the housing 1. A flue gas outlet 3 is provided at the upper end, and a stepped orifice plate 4 is fixedly arranged at the inner upper end of the housing 1, and the step height of the stepped orifice plate 4 near the flue gas inlet 2 is higher than that near the flue gas outlet 3 The height of the step is set, that is to say, based on the flow direction of the flue gas, the steps on the step-shaped orifice plate 4 are gradually reduced. A flue gas channel 5 is formed between the stepped orifice plate 4 and the upper part of the hous...

The invention discloses a configuration structure of a bag of a bag-type dust remover with a reasonable structure, comprising a shell. The front end of the shell is provided with a flue gas inlet; the upper part of the rear end of the shell is provided with a flue gas outlet; the upper end inside the shell is fixedly provided with a ladder-shaped orifice plate; the ladder setting height of the ladder-shaped orifice plate near the flue gas inlet is higher than the flue gas outlet near the flue gas outlet; a flue gas passage is formed between the ladder-shaped orifice plate and the upper part of the shell and is communicated with the flue gas outlet; the lower end of each ladder plane of the ladder-shaped orifice plate is fixedly provided with a bag-type dust removing unit; and each bag-type dust removing unit consists of a plurality of bags fixedly arranged on the lower ends of ladder planes. The configuration structure of the bag of the bag-type dust remover with the structure has reasonable flue gas flow field, can prevent overhigh partial wind speed and has good dust removing effect.
Description
technical field [0001] The invention relates to an arrangement structure of cloth bags in a bag filter. Background technique [0002] The arrangement structure of the bags in the existing bag filter includes: a shell, a smoke inlet is arranged in the middle of the front end of the shell, a smoke outlet is set in the upper rear end of the shell, and the inner upper end of the shell is fixed A horizontal orifice plate is provided, and a flue gas channel is formed between the orifice plate and the upper part of the housing, and the flue gas channel is connected with the flue gas outlet, and several cloth bags are fixedly arranged at the lower end of the orifice plate. During the dust removal process, the arrangement structure of the bag in the bag filter with this structure is unreasonable in the smoke flow field, and the wind speed is locally too high, so that the bag is damaged and the dust removal effect is not ideal. Contents of the invention [0003] The technical probl...
