Description

Technical Field

[0001] The invention relates to the technical field of resin waste gas treatment, and in particular to an environmentally friendly waste gas discharge treatment device for super absorbent resin production. Background Art

[0002] Since there are many types of pollutants in the waste gas, the waste gas composition is complex, including low-boiling point, volatile compounds, high concentration, difficult to treat, and obvious odor, so the existing waste gas treatment equipment is generally a comprehensive treatment process formed by multiple waste gas treatment methods, so as to treat resin waste gas with complex components. However, the waste gas from resin processing is generally intermittent and unorganized, and the concentration of waste gas discharged each time is uneven. In order to enable the device to have the ability to treat high-concentration harmful substances and large-displacement waste gas, the waste gas treatment equipment is generally set with a larger power and volume. However, due to the intermittent emission of resin processing waste gas, the amount of discharged waste gas and the concentration of harmful substances are both random. After the small-displacement and low-concentration harmful substance waste gas enters the waste gas treatment equipment, it is still treated by high-power equipment, making the equipment work insufficiently saturated, resulting in energy waste. And the larger the space for the device to treat the waste gas, and the higher the concentration of waste gas is introduced into the waste gas treatment equipment, it is difficult to ensure that all harmful gases in the waste gas are treated and purified, and it is easy for the residual harmful gas that is not treated sufficiently to be directly discharged into the air.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 6 The present invention provides a technical solution: an environmentally friendly waste gas discharge treatment device for the production of super absorbent resin, comprising a waste gas treatment tank 1 and a water storage tank 2 fixed at the bottom of the waste gas treatment tank 1, a waste gas introduction pipe 4 is fixedly installed on the left side of the bottom of the waste gas treatment tank 1, and an air introduction pipe 5 is fixedly installed on the waste gas introduction pipe 4. A spray water washing device, an activated carbon adsorption device and a photolysis device are arranged in the waste gas treatment tank 1, and the activated carbon adsorption device includes:

[0027] The left side plate 12 is provided with a plurality of groups and is fixedly mounted on the left inner wall of the exhaust gas treatment tank 1. The left and right ends of the left side plate 12 are horizontal plates, and the horizontal plates at the two ends are fixedly connected by an inclined plate;

[0028] The right side plate 13 is provided with multiple groups and is fixedly mounted on the right inner wall of the exhaust gas treatment tank 1. The left and right ends of the right side plate 13 are also horizontal plates, and the inclination direction and angle of the inclined plate connected in the middle are consistent with the inclined plate in the middle position of the right side plate 13. The left side plate 12 and the right side plate 13 are staggered in the exhaust gas treatment tank 1;

[0029] An activated carbon adsorbent 14 is provided at one end of the left side plate 12 and the right side plate 13 away from the inner wall of the waste gas treatment tank 1. A separate waste gas purification space is formed between the activated carbon adsorbent 14 and the left side plate 12 and the right side plate 13. A plurality of groups of left side plates 12 and right side plates 13 are staggered to form a plurality of groups of vertically distributed waste gas purification spaces. Waste gas can enter this waste gas purification space through the activated carbon adsorbent 14 below, and then be discharged through the activated carbon adsorbent 14 above. After being discharged, the waste gas can enter a new waste gas purification space again.

[0030] During operation, low-concentration exhaust gas in the present invention directly enters the exhaust gas treatment tank 1, while high-concentration exhaust gas is mixed with the air introduced by the air inlet pipe 5, and enters the exhaust gas treatment tank 1 after the concentration is reduced. After the low-concentration exhaust gas enters the exhaust gas treatment tank 1, it is firstly sprayed and washed by a spray water washing device for preliminary purification. After the preliminary purification, the exhaust gas rises and passes through the activated carbon adsorption component 14 in turn to enter the exhaust gas purification space formed by the left plate 12 and the right plate 13. The exhaust gas is further purified by the photolysis equipment in the exhaust gas purification space to adapt to the irregular discharge of resin exhaust gas, avoiding the previous use of high-power and large-volume equipment to adapt to the treatment of high-concentration exhaust gas, and the occurrence of unsaturated work when treating low-concentration exhaust gas, resulting in energy waste. In addition, after the low-concentration exhaust gas enters the exhaust gas treatment tank 1, the low-concentration exhaust gas is purified through multiple groups of vertically distributed exhaust gas purification spaces to ensure that harmful components in the exhaust gas can be fully purified, thereby improving the purification quality of the device for exhaust gas. Every time the exhaust gas enters and exits the exhaust gas purification space, it passes through the activated carbon adsorbent 14. The activated carbon adsorbent 14 is set at the edge of the exhaust gas purification space with a narrow volume, so that the contact position between the exhaust gas and the activated carbon adsorbent 14 is more concentrated, avoiding the situation where the surface of the activated carbon adsorbent 14 is in uneven contact with the exhaust gas, and avoiding the situation where the activated carbon adsorbent 14 in some positions is saturated and needs to be replaced while the activated carbon adsorbent 14 at the edge is still in a purifiable state, thereby reducing the waste that may be caused by replacing the activated carbon adsorbent 14.

[0031] As a further solution of the present invention, a mixing element 8 is fixedly installed on the exhaust gas inlet pipe 4, the lower end of the air inlet pipe 5 is introduced into the mixing element 8, and a one-way valve 6 is fixedly installed on the air inlet pipe 5, and the one-way valve 6 can allow external air to enter the mixing element 8 through the air inlet pipe 5.

[0032] During operation, a suction pump is provided at the upper end of the air inlet pipe 5. After the high-concentration exhaust gas enters the exhaust gas inlet pipe 4, the suction pump on the inlet pipe 5 is turned on to introduce the external air into the mixing element 8 through the air inlet pipe 5, so that the external air is mixed with the high-concentration exhaust gas, thereby reducing the concentration of harmful substances in the exhaust gas entering the exhaust gas treatment tank 1.

[0033] As a further solution of the present invention, the photolysis equipment includes multiple groups of UV photolysis equipment 16, and the UV photolysis equipment 16 is provided with multiple groups and evenly distributed on the upper and lower sides of the inclined plate between the left plate 12 and the right plate 13, and the two ends of the UV photolysis equipment 16 are fixedly connected to the inner wall of the waste gas treatment tank 1, and the UV photolysis equipment 16 can purify low-concentration harmful gases.

[0034] During operation, the UV photolysis equipment 16 is distributed on the upper and lower sides of the exhaust gas purification space formed by the left plate 12 and the right plate 13. The exhaust gas enters the exhaust gas purification space after being filtered by the activated carbon adsorption element 14. The harmful parts in the exhaust gas are cracked by ultraviolet rays through the UV photolysis equipment 16. The exhaust gas purification space compresses the exhaust gas and enters the exhaust gas treatment tank 1 for purification in the working space, so that the exhaust gas is more fully in contact with the UV photolysis equipment 16, thereby improving the purification efficiency. The exhaust gas enters the vertically distributed exhaust gas purification space in turn, and undergoes multiple rounds of purification by the UV photolysis equipment 16, thereby making the exhaust gas purification more thorough and clean.

[0035] As a further solution of the present invention, the spray water washing equipment includes a spray part 11, which is located at the lower end of the waste gas treatment tank 1. The spray part 11 includes an internal connecting pipe 1102 and an external connecting pipe 1103. The internal connecting pipe 1102 is provided with multiple groups and is horizontally distributed at the bottom of the waste gas treatment tank 1. The external connecting pipe 1103 is located outside the waste gas treatment tank 1, and one end of the internal connecting pipe 1102 passes through the waste gas treatment tank 1 and extends into the external connecting pipe 1103. Multiple groups of spray heads 1101 are fixedly installed on the lower surface of the internal connecting pipe 1102.

[0036] During operation, after the exhaust gas enters the exhaust gas treatment tank 1, water enters the internal connecting pipe 1102 through the external connecting pipe 1103, and the exhaust gas is sprayed by the spray head 1101 below the internal connecting pipe 1102 to perform preliminary purification on the exhaust gas, and the rising speed of the exhaust gas entering the exhaust gas treatment tank 1 is suppressed to ensure that the exhaust gas can gradually enter the exhaust gas purification space.

[0037] As a further solution of the present invention, a lower limit plate 10 is fixedly installed at a position between the top of the spray part 11 and the bottom of the lower left plate 12 in the waste gas treatment tank 1, and a suction fan 15 is fixedly installed at the upper end of the waste gas treatment tank 1, and the suction fan 15 can suck the waste gas upward.

[0038] During operation, the suction fan 15 rotates to suck the waste gas in the waste gas treatment tank 1 upward, ensuring that the waste gas can be gradually discharged to the waste gas outlet pipe 9 above.

[0039] As a further solution of the present invention, a buffer tank 7 is fixedly installed on the end of the exhaust gas inlet pipe 4 corresponding to the mixing element 8 away from the exhaust gas treatment tank 1, a pressure sensor is fixedly installed in the buffer tank 7, and an exhaust gas outlet pipe 9 is fixedly installed on the upper end of the exhaust gas treatment tank 1.

[0040] During operation, after a large amount of exhaust gas enters the exhaust gas inlet pipe 4 , the exhaust gas treatment tank 1 may not be able to process it in time. The exhaust gas can be stored in the buffer tank 7 in advance to relieve the purification pressure of the exhaust gas treatment tank 1 .

[0041] As a further solution of the present invention, the side walls of the waste gas treatment tank 1 are clamped with side clamping plates 3 at positions corresponding to the activated carbon adsorbent 14, and sealing gaskets are provided at the connections between the side clamping plates 3 and the waste gas treatment tank 1. A limiting protrusion is provided on the side of the activated carbon adsorbent 14 away from the side clamping plate 3, and a limiting groove is provided on the end of the left plate 12 and the right plate 13 away from the side wall of the waste gas treatment tank 1, and the limiting groove can be matched with the limiting protrusion, and the activated carbon adsorbent 14 can be fixed to one end of the left plate 12 or the right plate 13 through the limiting protrusion.

[0042] During operation, when the activated carbon adsorbent 14 needs to be replaced, the user can remove the activated carbon adsorbent 14 by opening the side clamping plate 3 , so as to facilitate the replacement of the activated carbon adsorbent 14 .

[0043] As a further solution of the present invention, a plurality of groups of stirring rods are provided at the bottom of the water storage tank 2 , and a rotating ring is provided at the bottom of the plurality of groups of stirring rods, and the rotating ring is rotatably connected to the bottom of the water storage tank 2 .

[0044] During operation, the stirring rod is driven to rotate by the rotating ring, and the water at the bottom of the water storage tank 2 is driven to rotate by the rotating ring, so that the water is more fully in contact with harmful substances in the exhaust gas, thereby increasing the water's ability to adsorb harmful substances.
