Description

Technical Field

[0001] The invention relates to the technical field of pigment production, and in particular to a high-efficiency waste gas treatment device for pigment production. Background Art

[0002] Pigment is a substance used for coloring, usually used in painting, printing, dyes, cosmetics and other fields. Pigments can reflect specific colors or light to the human eye, and produce different color effects through their chemical composition, structure and physical properties. Pigment production is a process involving chemical synthesis and physical processing, aimed at producing pigments with specific colors, stability and functions. The production of pigments starts with the selection of raw materials, which usually include minerals, chemical reagents and solvents.

[0003] In the pigment production process, the generation of waste gas is inevitable, especially in the chemical synthesis, grinding, drying and packaging links. The waste gas may not only contain harmful substances, but also pollute the environment. The waste gas generated in the pigment production process mainly includes: volatile organic compounds (VOCs): such as benzene, toluene and other organic solvents, acidic gases: such as chlorine (Cl2), hydrogen chloride (HCl), dust and particulate matter: such as tiny powder of pigment, oxide particles, etc.

[0004] However, the existing pigment waste gas treatment process is not ideal in terms of purification efficiency and effect, and the harmful substances in the waste gas cannot be fully removed. The energy consumption in the waste gas treatment process is large, which increases the operating cost. The maintenance and parts replacement process is relatively cumbersome, the downtime is long, and the maintenance cost is high. Therefore, the present invention proposes a high-efficiency waste gas treatment device for pigment production to solve the problems mentioned in the above background technology.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention drives the impeller to rotate through the bellows and the driving device to ensure that the exhaust gas quickly enters the interior of the air inlet cone seat, and adopts the adsorption method and the absorption method to treat the exhaust gas.

The exhaust gas is quickly and naturally connected through the two processes of adsorption and absorption, and most of the components are controlled by a single drive device to drive the work simultaneously, which reduces manual intervention, accelerates the exhaust gas treatment process, and achieves higher energy-saving effects.

[0020] In summary, the present invention combines the two waste gas treatment technologies of adsorption and absorption, which can effectively remove harmful substances in the waste gas and has efficient purification ability. The equipment is reasonably designed and has high energy efficiency, which reduces energy consumption and the need for manual intervention. The replacement design of the filter element and the adsorption seat makes maintenance simple and improves the stability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

The cyclone cone 12 is located at the lower side of one end of the inlet pipe 10. The exhaust gas enters the treatment chamber 1 through the air inlet cone seat 2. During this period, it needs to pass through the spiral air duct 20 and the filter element 23 in the adsorption seat 7. The filter element 23 is or molecular sieve. Activated carbon has a strong adsorption capacity for most volatile organic compounds (VOCs), especially for organic solvents with higher concentrations. Molecular sieve is suitable for adsorbing low molecular weight organic solvents (such as alcohols, ketones, etc.); the adsorbed exhaust gas enters the treatment chamber 1 for secondary treatment;

[0030] Furthermore, referring to Figure 1 , 2 , and the filter element 23 inside the adsorption seat 7 of the air inlet cone seat 2 can be replaced, a sealing rubber ring corresponding to the air inlet cone seat 2 is arranged on the lower side of the movable frame seat 3, a plurality of sliders are arranged on the outer side of the upper part of the movable frame seat 3, a plurality of slide grooves corresponding to the sliders are opened in the processing chamber 1, and a closing plate 17 corresponding to the slide grooves is fixed on the outer side of the slider, and limit blocks 22 are arranged on both sides of the water outlet 18 of the movable frame seat 3, and limit rotation pins corresponding to the limit blocks 22 are arranged on the left and right sides of the lower outer side of the processing chamber 1. The movable frame seat 3 inside the processing chamber 1 is pulled upward, so that the plurality of adsorption seats 7 in the air inlet cone seat 2 lose the suppression of the upper movable frame seat 3 , the adsorption seat 7 can be pulled out from the inside of the air inlet cone seat 2 to replace the filter element 23, and the limit rotation pin is rotated to the lower side of the limit block 22, which can fix the upper and lower heights of the movable frame seat 3 that slides up to the top. After replacing the filter element 23, the movable frame seat 3 is lowered, and its lower side is closely attached to the surface of the air inlet cone seat 2, while pressing the adsorption seat 7 for replacing the filter element 23, and the sealing rubber ring on the lower side of the movable frame seat 3 seals and connects the upper processing chamber 1 with the air inlet cone seat 2, so that the interior of the processing chamber 1 becomes a relatively sealed processing space, and the closing plate 17 fixed on the outer side of the slider also plays the role of closing the processing chamber 1;

[0031] Furthermore, referring to Figure 3, 6 The air inlet cone seat 2 is fixedly mounted with a bellows 5, an impeller is mounted inside the bellows 5, a driving device 19 is mounted on the upper side of the bellows 5, the lower end of the output shaft of the driving device 19 is connected to the lower impeller, an air inlet pipe is mounted on one side of the bellows 5, and a connecting pipe is mounted between the other side of the bellows 5 and the lower inlet of the air inlet cone seat 2, the exhaust gas is introduced into the air inlet cone seat 2 through the rotating impeller, and when the driving device 19 is started, the exhaust gas duct connected to the air inlet pipe of the bellows 5 rotates the impeller to quickly introduce the exhaust gas into the connected air inlet cone seat 2;

[0032] Furthermore, the upper end of the output shaft of the driving device 19 is connected to the rotating shaft 6, and a stirring paddle 16 connected to the rotating shaft 6 is arranged in the solvent chamber 4. A plurality of water outlet holes are evenly opened at the lower part of the cyclone cone 12. A spur gear 11 is fixed to one end of the inlet pipe 10, and an annular tooth groove corresponding to the meshing spur gear 11 is arranged on the upper side of the cyclone cone 12. The other end of the inlet pipe 10 is connected to the water inlet drum 13 located at the outlet of the solvent chamber 4, and a through groove corresponding to the outlet is arranged in the water inlet drum 13, and a gear 2 14 is fixed to the outer end of the water inlet drum 13. An end gear 15 is fixed to the peripheral side of the rotating shaft 6, and the end gear 15 is located at the lower side of the gear 2 14, and the end gear 15 is meshed with the upper gear 2 14. When the driving device 19 is started, the output The shaft 6 connected to the shaft rotates, and the stirring paddle 16 fixed on the upper end of the shaft 6 rotates.

The inner end of the inlet pipe 10 is connected to the gear 1 11 and the cyclone cone 12 through the corresponding annular tooth grooves, so that the cyclone cone 12 rotates. The medicine in the inlet pipe 10 flows into the rotating cyclone cone 12 and is discharged through a plurality of water outlets on the lower side. The liquid solvent (such as water or an organic solvent) absorbs the volatile solvent in the rising exhaust gas passing through, and the solvent vapor is dissolved in the liquid solvent.

[0033] Furthermore, referring to Figure 4 A water outlet 18 is provided on the lower side of the outer side of the movable frame seat 3, and a top cover 21 located inside the treatment chamber 1 is fixed on the upper side of the air inlet cone seat 2. An exhaust pipe 9 is installed on the upper side of the treatment chamber 1. The liquid mixed with volatile organic solvents falls on the surface of the air inlet cone seat 2. Due to the obstruction of the top cover 21, the falling water is prevented from flowing into the spiral air duct 20, and due to the effect of the sealing rubber ring, the mixed liquid solvent is discharged through the water outlet 18 on the outer side of the movable frame seat 3. The solvent dissolved in the absorbent can be regenerated by heating or reducing pressure to release and recover the solvent vapor, and the exhaust gas that has passed the two purification procedures is discharged through the upper exhaust pipe 9.
