TECHNICAL FIELD
[0001] The utility model relates to laundry detergent production technical field especially relates to a laundry detergent production tail gas spray dust removal device. BACKGROUND
[0002] In the production process of laundry detergent, it usually involves mixing, grinding, drying and other process steps of various raw materials. Due to the dust and gas emission of raw materials in the production process and the operation of equipment, a large amount of dust and harmful gas may be produced. If these substances are directly discharged without treatment, not only the environment will be polluted, but also the human health may be affected. Therefore, controlling the tail gas emission in the production process and reducing dust pollution have become urgent problems in the laundry detergent production industry.
[0003] A laundry detergent production tail gas spray dust removal device is disclosed in Chinese patent No. CN217855263U. The first pulley is driven to rotate by the motor, which in turn drives the second pulley to rotate through the conveyor belt, causing the spray head to rotate, allowing the spray liquid to be sprayed at various angles and contact with the tail gas. The setting of the circulation pipe allows the reacted raw liquid to be recovered in the liquid storage tank for reuse. The setting of the filter screen allows the impurities left after the reaction to be filtered out, avoiding the use of impurities in the next reaction. The setting of the adsorption plate allows the small solids present in the tail gas to be adsorbed. The setting of the rotating assembly allows the spray cylinder to rotate with the rotating assembly, increasing the contact area between the raw liquid and the tail gas. The combination of the above components can effectively solve the problem of the existing laundry detergent production tail gas spray dust removal device, which is mostly sprayed from one angle. This spraying method is not uniform and has limited purification effect on organic fertilizer tail gas.
[0004] Although the above device can spray and remove dust from the tail gas, in actual use, the position of the filter screen is prone to accumulate dust, causing the circulation pipe to be blocked, resulting in the liquid pump being unable to extract the circulating liquid, causing difficulty in use. The dust filtered by the filter screen is not easy to clean, which is not convenient to use. At the same time, the contact area between the water mist and the gas is small when the device sprays the tail gas, resulting in a significant reduction in pollutant removal efficiency, especially for small particles. After spraying and removing dust, the moisture in the gas cannot be effectively removed, which is prone to form wet gas emission, which needs to be improved. UTILITY MODEL CONTENTS

[0031] Circulation assembly includes water pump 14 fixedly installed at the top of liquid tank 3, the water inlet of water pump 14 is fixedly connected with liquid tank 3, the water outlet of water pump 14 is fixedly connected with shunt pipe 15, two ports of shunt pipe 15 are fixedly connected with annular pipe 6, filter assembly includes limiting frame 16 fixedly installed on the inner wall of liquid tank 3, limiting groove 17 is formed in limiting frame 16, filter plate 18 is clamped on limiting groove 17.
[0032] The bottom of the tank body 4 is fixedly connected with a recovery pipe 19, the recovery pipe 19 is fixedly connected with the liquid tank 3, the outer wall of the tank body 4 is fixedly connected with two observation windows 20 and an air inlet 21 respectively, the observation windows 20 can observe the inside of the tank body 4, the top of the tank body 4 is fixedly connected with a suction fan 22, the air inlet of the suction fan 22 is fixedly connected with the cylinder 10, and the outlet of the suction fan 22 is fixedly connected with an air outlet 23.
[0033] Working principle: first, the tail gas that needs to be sprayed and dedusted is connected to the air inlet 21, then the suction fan 22 can be started, so that the gas is continuously extracted to provide the necessary flow power for the gas, then the water pump 14 is started, and the water inlet extracts the spraying liquid in the liquid tank 3, then the spraying liquid enters the distribution pipe 15 along the water outlet, under the action of the annular pipe 6, the spraying liquid sprayed by the spraying head 7 forms a water mist, the exhaust gas contacts the water mist in the tank body 4 and the surface of the filler 8 when passing through the tank body 4, and the pollutants (such as dust, acid gas, alkaline gas, etc.) in the gas are adsorbed, dissolved or reacted with the liquid, so as to purify the exhaust gas. After the exhaust gas passes through the filler 8 and the spraying atomization area, the purified gas continues to flow upward, and when the gas passes through the demister 9, the water droplets in the gas flow are separated and recycled to the tower for circulation. The gas treated by demisting continues to flow upward under the action of the suction fan 22, enters the activated carbon layer 12, is further treated by the activated carbon, and the purified exhaust gas is discharged through the air outlet 23;
[0034] The liquid is sent to the spraying head 7 by the water pump 14 for spraying, and flows to the bottom after spraying, enters the recovery pipe 19, and is then transported to the liquid tank 3. After a period of spraying, the spraying liquid will accumulate suspended solids, dust, fine particulate matter and other solid impurities. At this time, the filter plate 18 blocks the impurities in the spraying liquid to prevent the impurities from re-entering the spraying system or the filler 8 layer during the circulation process, thereby reducing the risk of clogging, fouling or reduced spraying effect. After a period of use, the blocked impurities can be cleaned by opening the cover plate 11. When the filter plate 18 needs to be cleaned, it can be easily separated by lifting the filter plate 18. After cleaning, the filter plate 18 is clamped along the limiting groove 17 on the limiting frame 16, and then the cover plate 11 is closed. The cover plate 11 can further limit the movement of the filter plate 18 after being closed, thereby facilitating the cleaning of the impurities and the maintenance of the filter plate 18, and facilitating the use of the staff.
