Fig. 1 is a schematic structural diagram of the odor washing tower of the pulp mill.
Wherein: 1-tower body (101-air inlet, 102-air outlet), 2-first spray device, 3-water spray tray (301-tray, 302-absorption hood), 4-pall ring packing layer, 5-second spray device, 6-demister, 7-third spray device, a-nozzle.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the odor washing tower of the pulp mill mainly has the functions of washing, cooling and dedusting the odor of the pulp mill, and comprises a tower body 1, a first spraying device 2, a water spraying disc 3, a pall ring packing layer 4 and a second spraying device 5.
The side wall of the tower body 1 close to the bottom is provided with an air inlet 101, and the top of the tower body is provided with an air outlet 102. Preferably, the intake port 101 is an intake pipe disposed to be inclined downward. The odor of the pulp mill enters the washing tower from the air inlet 101 at the bottom of the washing tower, the air inlet 101 is an air inlet pipe which is arranged in a downward inclination mode, the odor enters the tower body 1 and slightly inclines downward, and the gas can be ensured to flow upwards more uniformly.
The first spraying device 2 is arranged in the tower body 1 and close to the upper portion of the air inlet 101, and a plurality of nozzles a are arranged on the first spraying device 2. Preferably, the nozzle a is a spiral nozzle which can prevent the nozzle from being scaled and blocking the spray head. Preferably, the nozzles a of the first spray device 2 are opened downward so that the spray space of the nozzles can fully cover the entire odor inlet plane when the first spray device 2 is used. The first layer of spraying device 2 mainly has the function of removing dust and particles carried in odor.
The shower tray 3 sets up 2 tops of first spray set, the shower tray 3 is including locating a plurality of tray 301 of its upper portion's dish mouth up and locating the cage 302 of its lower part, staggered arrangement about a plurality of tray 301, the last edge of having seted up of cage 302 the absorption chamber that vertically link up of tower body 1. The shower water flows out from the top to the bottom from two sides of the shower tray 3 to form a water film, the odor passes through the water film from bottom to top, and dust and salt in the odor can be well captured, so that the purpose of dust removal is achieved. Preferably, the number of the water spraying discs 3 is determined by calculation.
