Abstract
The utility model discloses a caustic wash tower for $sulfonating tail gas treatment in technology, including the tower body, the top of tower body is equipped with the outlet duct, in the tower body from last to have the silk screen packing layer, go up the pall ring packing layer, shower and pall ring packing layer down, the bottom of shower is equipped with a plurality of nozzles, the below of lower pall ring packing layer is equipped with the gas access, is equipped with alkali lye bottom the side of tower body to export. During this caustic wash tower blocks effectively through upper and lower two -layer pall ring packing layer that na2SO3 and na2SO4 tiny particle are attached to water saturation tail gas, make in the reacted water saturation tail gas not gassiness foam and solid tiny particle, water saturation tail gas organizine net packing layer before the atmospheric dilution reduces the moisture content, makes the final tail gas that discharges reach the index of requirement, since in the processing procedure alkali lye number of cycles still less, carry the duty cycle who has reduced tail gas treatment in the sulphonate technology greatly, reduced the equipment energy consumption.
Description
Technical field
The utility model belongs to vent gas treatment technical field, is specifically related to a kind of caustic wash tower for process for sulfonation vent gas treatment.
Background technology
Caustic wash tower is the visual plant in tail gas treating unit in process for sulfonation, from the tail gas of sulphonator, removes organic matter and unreacted SO through processing3And SO2After be drained in atmosphere. Unreacted SO3Conventionally exist with smog form, remove by electrostatic precipitator, but still contain the unconverted SO of part in electrostatic precipitator gas after treatment2Can remove by caustic wash tower the soda bath in caustic wash tower and SO2Reaction generates sodium sulfite, and part sodium sulfite is oxidized to sodium sulphate, and tail gas and water form saturated tail gas and enters in atmosphere.
Existing caustic wash tower SO in alkaline cleaning procedure2Shorter with the time of contact of alkali lye, response area is also less, can not fully effectively absorb SO2, and the Na generating2SO3There is again part to be become Na by the dioxygen oxidation in tail gas2SO4, because their particle is very little, conventionally can, along with water saturation tail gas enters atmosphere together, cause pollution to environment and atmosphere.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of caustic wash tower for process for sulfonation vent gas treatment, and this caustic wash tower flux is large, and resistance is little, and separate absorbent efficiency is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of caustic wash tower for process for sulfonation vent gas treatment, comprise tower body, the top of tower body is provided with escape pipe, in tower body, be provided with from top to bottom wire packing layer, upper Pall ring filler layer, shower and lower Pall ring filler layer, one end of shower is through tower body, and as alkali liquor inlet, the bottom of shower is provided with some nozzles, the below of lower Pall ring filler layer is provided with gas access, and the side bottom of tower body is provided with alkali lye outlet.
Between top one side, shower and the lower Pall ring filler layer of described tower body, the side of lower Pall ring filler layer is equipped with manhole.
The thickness of described wire packing layer is 60-120mm, and the thickness of upper Pall ring filler layer is 300-400mm, and the thickness of lower Pall ring filler layer is 2500-3000mm.
Compared with prior art, the utility model has the advantages that: this caustic wash tower is rational in infrastructure reliable, effectively stops Na by upper and lower two-layer Pall ring filler layer2SO3And Na2SO4Granule is attached in water saturation tail gas, makes in reacted water saturation tail gas not containing air foam and solid granule; Water saturation tail gas reduces moisture content entering before atmosphere through silk screen packing layer, makes the tail gas of final discharge meet the requirements of index; Due to the cycle-index of alkali lye in processing procedure still less, greatly carry and reduced the work period of vent gas treatment in process for sulfonation, reduced equipment energy consumption.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, tower body, 2, lower Pall ring filler layer, 3, shower, 31, nozzle, 4, upper Pall ring filler layer, 5, wire packing layer, 6, gas access, 61, escape pipe, 7, alkali liquor inlet, 71, alkali lye outlet, 8, manhole.
Detailed description of the invention:
As shown in Figure 1, a kind of caustic wash tower for process for sulfonation vent gas treatment, comprise tower body 1, the top of tower body 1 is provided with escape pipe 61, in tower body 1, be provided with from top to bottom wire packing layer 5, upper Pall ring filler layer 4, shower 3 and lower Pall ring filler layer 2, one end of shower 3 is through tower body 1, as alkali liquor inlet 7, the bottom of shower 3 is provided with some nozzles 31, the below of lower Pall ring filler layer 2 is provided with gas access 6, the side bottom of tower body 1 is provided with alkali lye outlet 71, top one side of tower body 1, between shower 3 and lower Pall ring filler layer 2, the side of lower Pall ring filler layer 2 is equipped with manhole 8, be convenient to real-time examination and repair and maintenance.
In caustic wash tower of the present utility model, wire packing layer 5 is selected stainless steel, and thickness is 60-120mm; Upper Pall ring filler layer 4 and lower Pall ring filler layer 2 are selected PP material, and thickness is respectively 300-400mm and 2500-3000mm.
Containing SO2Tail gas enter from gas access 6 in tower body 1 upwards and carry, alkali lye enters shower 3 from alkali liquor inlet 7, drench to lower Pall ring filler layer 2 by nozzle 31, the alkali lye that flows through lower Pall ring filler layer 2 flows out from alkali lye outlet 71, again flows into alkali liquor inlet 7 and circulate under the effect of circulating pump; Tail gas first fully reacts with the alkali lye being attached on lower Pall ring filler layer 2, then, by upper Pall ring filler layer 4, once anhydrates, then carrying out secondary by wire packing layer 5 anhydrates, finally be expelled to atmosphere from escape pipe 61, in the tail gas of discharge, SO2Concentration can be down to below 5ppm, and in the situation that wire packing layer 5 is not set, SO2Concentration reaches 1000ppm left and right.
