Gravity spraying washer for dusty gas

Abstract

The invention discloses a gravity spraying washer for dusty gas. The gravity spraying washer comprises a shell, wherein a dusty gas inlet is formed in the sidewall of the shell; an exhaust port for purified gas is formed in the top of the shell, and a discharge outlet is formed in the bottom of the shell. The gravity spraying washer is characterized in that a plurality of first clear water pipe nests are arranged in parallel at equal intervals at positions, certain distances away from the top of the dusty gas inlet, in the shell, wherein a plurality of first nozzle sets are arranged at equal intervals under the first clear water pipe nests; a plurality of second clear water pipe nests are arranged in parallel at equal intervals at positions, certain distances away from the tops of the first clear water pipe nests, in the shell; a plurality of second nozzle sets are arranged at equal intervals under the second clear water pipe nests; baffle plates are arranged between the tail ends of the first clear water pipe nests and the shell; the first and second nozzle sets are spaced from each other. According to the gravity spraying washer, blind zones between a droplet space and the shell are reduced, and a purification effect is improved.

Description

technical field [0001] The invention relates to a gravity spray scrubber for dusty gas. Background technique [0002] Gravity spray scrubber is the simplest type of scrubber. When the dust-laden gas passes through the droplet space formed by the spray liquid, due to the inertial collision, interception and condensation between the sediment and the droplet, it is relatively large. The particles are captured by the droplets, which can effectively purify particles above 50μm. [0003] In the traditional gravity spray scrubber, there is a large "blind zone" between the droplet space formed by the spray liquid and the shell, that is, the area where the dusty gas cannot be purified, resulting in unsatisfactory purification effect. Contents of the invention [0004] In view of the above problems, the present invention provides a gravity spray scrubber for dust-laden gas. By improving the structure of the existing gravity spray scrubber, the "blind area" between the droplet space...
