Embodiment 1

[0030] like figure 2As shown, the main technological process for the recovery of high-concentration organic waste gas in this embodiment includes: the high-concentration organic waste gas collected by the gas collecting hood of the production workshop and the reactor pipeline enters the high-efficiency absorption tower, and the structure inside the absorption tower improves the organic waste gas and the recombination. The contact surface area of ​​the adsorbent, the composite adsorbent preparation system automatically quantitatively prepares the corresponding concentration through the waste gas concentration of the organic waste gas, and uses the principle of similar compatibility to absorb the liquid to dissolve the organic waste gas. It also relies on the microbubbles produced by the adsorbent to increase the absorption contact surface area to enhance the absorption effect of organic waste gas; relying on the porous microgel produced in the absorption process to coat organic...

Embodiment 2

[0033] like figure 1 As shown, this embodiment is used to specifically disclose a high-efficiency absorption tower for high-concentration organic waste gas. The high-efficiency absorption tower includes a tower wall 7. The organic waste gas enters the high-efficiency absorption tower tangentially into the intake pipe 1, and the waste gas moves upwards along the tower wall 7 under the guidance of the deflector 2, and the viscous dust particles in the waste gas are thrown towards the tower wall 7 under the action of the rotating centrifugal force. , the adsorbent flowing down from the liquid collection area of ​​the swirl plate 5 forms a layer of liquid film on the tower wall 7, and the viscous dust particles thrown onto the tower wall 7 are adhered by the liquid film to be purified. The vertical height of the inlet pipe 1 is slightly higher than The vertical height of the discharge pipe 18, a deflector 2 is arranged between the tower walls 7, a liquid film forming baffle 3 is a...

Embodiment 3

[0035] The difference between this embodiment and Embodiment 2 is that: the end of the drain pipe 18 away from the tower wall 7 is provided with a waste liquid treatment tank A00, and the waste liquid treatment tank A00 can process the waste liquid of the high-efficiency absorption tower in time to prevent the waste liquid from directly The discharge causes environmental pollution, and the waste water is purified by spraying out the treatment liquid. At the same time, the raw materials of the treatment liquid can be directly put into the hopper A02 for mixing. While mixing, the treatment liquid is transported from left to right , so as to improve the efficiency of waste liquid treatment.

[0036] like image 3 As shown, the waste liquid treatment box A00 is connected with the drain pipe 18, the side of the waste liquid treatment box A00 away from the drain pipe 18 is fixedly connected with the liquid outlet pipe A01, and the inner top wall of the waste liquid treatment box A00...

Abstract

The invention belongs to the field of waste gas treatment, relates to an organic waste gas recovery technology, aims to solve the problem of high difficulty in high-concentration waste gas treatment in the prior art, and particularly relates to a high-concentration organic waste gas treatment and recycling system, which comprises an efficient absorption tower, the two inner side walls of the tower walls are fixedly communicated with a gas inlet pipe and a liquid discharge pipe respectively, a waste liquid treatment box is arranged at one end, far away from the tower walls, of the liquid discharge pipe, a flow guide plate is arranged between the tower walls, a liquid film forming baffle is arranged above the flow guide plate, a rotational flow plate is mounted on the liquid film forming baffle, and the rotational flow plate is provided with a liquid outlet. The rotational flow plate and the liquid film forming baffle plate are combined to form a rotational flow liquid collecting area; the composite absorption and purification technology based on water and the surfactant is suitable for purification of low-concentration and large-air-volume complex organic waste gas containing organic matter and the like, the surface tension has important influence on the absorption process, and the surface tension of the composite absorbent is reduced.

Description

technical field [0001] The invention belongs to the field of waste gas treatment, and relates to an organic waste gas recovery technology, in particular to a high-concentration organic waste gas treatment, recovery and reuse system. Background technique [0002] The waste gas volatilized from the reaction kettles used in some domestic chemical industry, pharmaceutical industry, printing industry and other process links is a high-concentration organic waste gas. Its treatment characteristics: high-concentration organic waste gas is generally flammable, toxic and harmful. It is soluble in organic solvents and difficult to handle. [0003] In the printing production process of tipping paper in the ink printing industry, a large amount of organic solvents and a small amount of ethyl acetate and other solvents are used to dissolve the polymer resin. emission. It is estimated that the major tipping paper printing manufacturers in the country consume up to tens of thousands of to...
