Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and more specifically to a waste gas treatment device for an acrylic resin polymerization reactor. Background Art

[0002] Acrylic acid is an important organic synthetic raw material and synthetic resin monomer. It is an ethylene monomer with a very fast polymerization speed. Acrylic acid and acrylic esters can be homopolymerized and copolymerized. The polymers are used in synthetic resins, synthetic fibers, highly absorbent resins, building materials, coatings, etc. In the prior art, acrylic emulsions are polymerized in a reactor by seed emulsion polymerization, prepolymerization, or continuous polymerization, so as to control the size and distribution of latex particles. However, when preparing acrylic emulsions and other series of products, the gas generated in the reactor is very irritating. If it is directly discharged, it will have a negative impact on the surrounding environment and the health of the operators. The prior art requires subsequent treatment of the waste gas generated during polymerization.

[0003] Existing methods for treating waste gas generated by acrylic resin polymerization include catalytic combustion, activated carbon adsorption and spray absorption. Among them, activated carbon adsorption is to lead the waste gas generated by acrylic resin polymerization to be treated from the air duct into the activated carbon adsorption filtration equipment, and the harmful substances in the gas are adsorbed by the activated carbon and attached to the surface of the activated carbon, so that the gas can be purified. However, most of the existing activated carbon adsorption equipment is a fixed structure with a fixed thickness of the activated carbon unit, which can only treat waste gas with a certain content of harmful substances. The waste gas generated by different polymerization methods of acrylic resin has different contents of harmful substances. The existing waste gas treatment device of acrylic resin polymerization reactor cannot effectively treat a variety of waste gases and has a single function. It is necessary to configure the waste gas treatment device of acrylic resin polymerization reactor according to the waste gas generated by the specific acrylic resin polymerization, resulting in high cost of waste gas treatment of acrylic resin polymerization reactor;

[0004] Moreover, activated carbon will be deactivated during long-term use, which is mainly manifested in a decrease in adsorption effect. Although water vapor can be used as a medium through the steam regeneration method to penetrate the interior of the activated carbon, decompose and desorb the adsorbate at high temperature, and then discharge it through the airflow, thereby restoring the adsorption performance of the activated carbon, in order to restore the vitality of the activated carbon, however, during the activated carbon adsorption process, the activated carbon at the bottom adsorbs more harmful substances, and the total loading amount of the activated carbon directly affects its service life. The larger the loading amount, the total amount of harmful substances that the activated carbon at the top contacts is relatively small, thereby extending the service life of the activated carbon. When replacing the activated carbon, it will cause waste of the top activated carbon, and it will also cause high cost of waste gas treatment of acrylic resin polymerization reactor. In view of this, we propose an acrylic resin polymerization reactor waste gas treatment device. Summary of the invention

[0054] In the embodiment of the present invention, the translation mechanism 3 includes a vertical wall 31, which is fixed to the top of the base 1, and two slide rails 32 are fixed on the vertical wall 31 in a parallel structure. Two sliders X33 are slidably connected to the slide rails 32, and the four sliders X33 are fixedly connected through a connecting seat 34. The connecting seat 34 is fixedly connected to the middle tower 27. A fixed seat 35 is provided above the connecting seat 34, and the fixed seat 35 is fixedly connected to the top tower 25. The present invention makes the middle tower 27 detachable through the arrangement of the filter tower mechanism 2 and the translation structure, and the translation mechanism 3 is arranged to assist the reassembly of the middle tower 27, so as to facilitate the replacement of the activated carbon in the placement mechanism 4 on the middle tower 27.

[0055] In the embodiment of the present invention, a rotating ring 421 is fixedly provided at the center of the hollow plate 42, and a plurality of triangular grooves A422 are provided in an annular structure with equal spacing on the inner edge surface of the rotating ring 421 located above, and the depth of the triangular groove A422 gradually increases in the clockwise direction, and a limiting column A423 is movably provided in the triangular groove A422, and the limiting column A423 is elastically connected to the deep part of the triangular groove A422 by a spring A424. Through the above arrangement, the present invention enables the limiting column A423 to be located in the middle of the triangular groove A422 under the elastic force of the spring A424 without the action of external force.

[0056] In an embodiment of the present invention, a plurality of triangular grooves B441 are provided in a circular equidistant structure at the top of the outer edge surface of the adjusting ring 44, the depth of the triangular groove B441 gradually increases in the clockwise direction, a limiting column B442 is movably provided in the triangular groove B441, the limiting column B442 is elastically connected to the deep part of the triangular groove B441 by a spring B443, the limiting column B442 is movably connected to the middle tower 27, and a plurality of triangular grooves C444 are provided in a circular equidistant structure at the top of the inner edge surface of the adjusting ring 44, the depth of the triangular groove C444 gradually increases in the clockwise direction, a limiting column C445 is movably provided in the triangular groove C444, and the limiting column C445 is elastically connected to the deep part of the triangular groove C444 by a spring C446.

Therefore, the adjusting ring 44 cannot rotate in the forward direction. When the adjusting ring 44 rotates counterclockwise relative to the middle tower 27, the limiting column B442 has a force to move along the deep part of the triangular groove B441 under the friction force of the middle tower 27, which has little effect on the counterclockwise rotation of the adjusting ring 44.

The inner edge surface of the connecting ring 491 is provided with a plurality of triangular grooves D494 in an annular equidistant structure. The depth of the triangular groove D494 gradually increases in a clockwise direction. A limiting column D495 is movably provided in the triangular groove D494.

The limiting column A423, the limiting column B442, the limiting column C445 and the two ends of the limiting column D495 are all in a hemispherical structure. The present invention adopts the structural design of the connecting assembly 49, which is the same as the principle of the above-mentioned adjustment ring 44. Fig. 9 and Fig.10It can be seen that since the adjustment ring 44 cannot rotate forward, when the connecting ring 491 rotates forward, the limiting ring 492 is driven to rotate forward through a number of diamond columns 493, and when the connecting ring 491 rotates reversely, the limiting ring 492 rotates reversely and drives the adjustment ring 44 to rotate reversely through the limiting column C445, wherein the limiting column A423, the limiting column B442, the limiting column C445 and the limiting column D495 are all provided with hemispherical structures at both ends to reduce their movement resistance.

The top end of the transmission block 64 is slidably matched with the transmission groove 72. Inclined surfaces 66 are provided on both sides of the top end of the transmission block 64. The inclined surfaces 66 are movably matched with the flange C20 and the transmission groove 72 located below.

At this time, the output shaft of the motor 61 is controlled to rotate by an external control mechanism, and the transmission shaft 62 drives the main shaft 71 to rotate through the transmission block 64.

[0062] The present invention designs the structures of the placement mechanism 4 and the mixing mechanism 5 so that when the output shaft of the motor 61 is controlled to rotate clockwise by the external control mechanism, the main shaft 71 rotates forward, driving the connecting shaft 77 and the connecting component 49 to rotate forward relative to the adjusting ring 44, that is, the size of the activated carbon placement chamber and the size of the mixing component 75 will not change, the mixing component 75 rotates as a whole, and the spiral blades A76 and B752 flip, break up and mix the activated carbon in the activated carbon placement chamber to prevent the activated carbon at the bottom from absorbing more harmful substances, so that the total amount of harmful substances in the exhaust gas absorbed by the activated carbon is relatively uniform, thereby improving the utilization rate of the activated carbon; when the output shaft of the motor 61 is controlled to rotate counterclockwise by the external control mechanism, the connecting shaft 77 cannot rotate reversely, and the connecting component 49 drives the adjusting ring 44 to rotate reversely, that is, the size of the activated carbon placement chamber and the size of the mixing component 75 are scaled at the same time.

[0063] Working principle: This embodiment provides an acrylic resin polymerization reactor waste gas treatment device. When in use, the thickness of the activated carbon is adjusted according to the content of harmful substances in the acrylic resin polymerization waste gas;

[0066] When the activated carbon is deactivated during use and does not meet the conditions for treating the waste gas from the polymerization of acrylic resin, the steam mechanism 8 is used to restore the activity of the activated carbon;
