Abstract
The utility model discloses a device for absorbing and purifying toxic harmful gas, which consists of an absorption tower body 3 and an absorption liquid pool 8, wherein the lower end of the absorption tower body 3 is provided with a liquid discharge pipe 9 and a gas inlet pipe 10; the liquid discharge pipe 9 is communicated with the absorption liquid pool 8; the inside of the absorption tower body 3 is provided with an upper and a lower layers of absorption liquid spray heads 4, 6 both connected with an absorption liquid pool pipe 7; the absorption liquid pool pipe 7 is provided with a pump; the upper part of the absorption tower body 3 is provided with an exhaust port 1 which can be connected with following absorption device; in addition, a liquid partition net 2 is arranged below the exhaust port arranged at the upper part of the absorption tower body 3. The utility model has the advantages of larger gas-liquid contact area and high efficiency of absorption and purification ,etc., thereby being suitable to be extensively used in absorbing and purifying toxic harmful gas.
Description
The utility model relates to a kind of emission-control equipment that improves hygienic conditions, specifically relates to a kind of toxic and harmful and purifies absorption plant.
Because harmful poisonous gas mostly is acid compound, as the plastics peculiar smell that produces in the plastics-production process mainly is sulfide, people's weak base absorption liquid commonly used absorbs, in order to increase assimilation effect, have and adopt multilayer to absorb, application (patent) number is 87215293.6, the applying date is the disclosed technology of patent that 1987.12.31, name are called absorption column of gas, and it is to be made of body of the tower, liquid-adding device, pedestal.It is simple and crude disposable absorption plant now, changes over the multilayer absorption plant of gas-liquid conversed convection current, improves absorptivity greatly.Place stripping liquid by liquid-adding device during use, every layer of dividing plate all has the skim absorbent, by lower guide tracheae input gas, upper airway is discharged tail gas, the solution that absorbed a large amount of gases is emitted by catheter, though this instrument is simple in structure, unit space gas-liquid contact developed surface is amid a sharp increase, then can not be handled for the alkali compounds in the harmful poisonous gas, the contact area of gas-liquid is still waiting further raising.
The purpose of this utility model just is to provide the toxic and harmful absorbing and purifying device that a kind of gas-liquid contact area is bigger, absorption cleaning is even more ideal.
For achieving the above object, the utility model adopts following scheme to realize: it constitutes by absorbing tower body and absorbing liquid pool, absorb the tower body bottom drain pipe and air inlet pipe are arranged, drain pipe is communicated with the absorption liquid pool, absorb tower body top the absorption liquid shower nozzle is arranged, this shower nozzle joins with absorption liquid pool pipeline, and absorbing tower body top is exhaust outlet, and this exhaust outlet can connect next step absorption plant.
Double-deck shower nozzle is up and down arranged in described absorption tower body, and shower nozzle all joins with absorption liquid pool pipeline, is provided with one deck plastic filler between the levels shower nozzle.
Below described absorption tower body upper air vent, a liquid isolating net is arranged.
After adopting said structure, owing to adopted shower nozzle simultaneously, produce spraying, make the contact-making surface of gas and absorption liquid bigger, double-deck shower nozzle absorption tower, it is closeer to produce spraying, the gas-liquid contact is more abundant, and the absorption cleaning effect is better naturally, simultaneously because the employing of liquid isolating net, can prevent effectively that the outer of absorption liquid from slopping over out, be unlikely to influence the assimilation effect of next device.When the exhaust outlet of tower body connects next absorption liquid absorption plant, as in tower body, adopting alkaline absorption solution, next device adopts acid absorption liquid, just can reach the acid compound that absorbs simultaneously in the toxic and harmful and the purpose of alkali compounds, and absorption cleaning is more thorough.Be described further below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model and the matching used structural representation of other absorption plant.
As shown in Figure 1, toxic and harmful absorbing and purifying device of the present utility model constitutes by absorbing tower body 3 and absorbing liquid pool 8, absorb tower body 3 bottoms drain pipe 9 and air inlet pipe 10 are arranged, drain pipe 9 is communicated with absorption liquid pool 8, absorb double-deck absorption liquid shower nozzle 4,6 is up and down arranged in the tower body 3, this shower nozzle 4,6 and absorption liquid pool pipeline 7 join, on the pipeline 7 pump is arranged, between the levels shower nozzle, be provided with one deck plastic filler 5, absorbing tower body 3 tops is exhaust outlet 1, this exhaust outlet 1 can connect next step absorption plant, below described absorption tower body 3 upper air vents a liquid isolating net 2 is arranged.
As shown in Figure 2, the utility model and the supporting use of other absorption plant, above-mentioned absorption liquid can adopt the caustic soda of dilution, be used to absorb acid compound, the exhaust outlet 1 that absorbs tower body 3 joins with next absorption plant 12, as this absorption plant 12 adopt one with absorb liquid storage tank 11 that liquid pool 16 communicates and with absorb shower nozzle 13 compositions that liquid pool pipeline 15 joins, shower nozzle 12 is positioned at a umbrella hat 14 belows, absorption liquid adopts weakly acidic aqueous solution, can be used for absorbing the alkali compounds in the toxic and harmful, thereby make absorption cleaning more thorough, through after this process, the gas of purification can enter in the atmosphere.Be widely used in the industries such as chemical industry, electronics, machinery purification or recovery to waste gas, tail gas.The absorption that is particularly useful for the peculiar smell in the plastics-production process is handled, and eliminates environmental pollution.
Claims (3)
1. toxic and harmful absorbing and purifying device, constitute by absorbing tower body and absorbing liquid pool, absorb the tower body bottom drain pipe and air inlet pipe are arranged, drain pipe is communicated with the absorption liquid pool, absorbing tower body top is exhaust outlet, and this exhaust outlet can connect next step absorption plant, it is characterized in that, absorbing in the tower body has the absorption liquid shower nozzle, and this shower nozzle joins with absorption liquid pool pipeline.
