[0035] The terms “first”, “second”, “third” and the like in the present invention do not represent specific quantities and sequences, but are merely used to distinguish names.

[0036] Reference Figure 1-Figure 9 As shown, the integrated waste gas adsorption tower of the utility model comprises:

[0037] The tower body 1 extends in a vertical direction, an air inlet 111 and a water injection port 112 are arranged on the side wall of the tower body 1, a liquid discharge port 113 is arranged at the bottom, and an exhaust port 121 is arranged at the top. The water injection port 112 is detachably connected to a sealing plug 114, and the liquid discharge port 113 is connected to a liquid discharge valve 115;

[0038] The filter assembly 2 is arranged in the tower body 1 and above the air inlet 111. The filter assembly 2 includes a dust filter 21 and an adsorbent 22 arranged in sequence from bottom to top. The circumferential outer edge of the dust filter 21 is fixedly connected to the circumferential inner wall of the tower body 1.

[0039] The water purification component 3 is arranged in the tower body 1 and enclosed with the inner wall of the tower body 1 to form a water purification chamber 13 separated from the liquid discharge port 113. The water purification component 3 is provided with a filter hole 321 connected with the water purification chamber 13;

[0040] The water pump 4 and the flushing assembly 5 are arranged in the tower body 1 and located between the dust filter 21 and the adsorption element 22. The input end of the water pump 4 is connected to the clean water chamber 13, and the output end is connected to the flushing assembly 5. The water pump 4 and the flushing assembly 5 cooperate with each other to flush and clean the dust filter 21.

[0041] When the integrated exhaust gas adsorption tower is used, the exhaust gas to be purified is introduced into the tower body 1 from the air inlet 111. When the exhaust gas carrying particulate matter flows upward in the tower body 1 through the filter assembly 2, it first contacts the dust filter 21, and the particulate matter in the exhaust gas is filtered by the dust filter 21, and then the harmful substances in the exhaust gas are adsorbed by the adsorbent 22 to achieve the purpose of exhaust gas purification. The purified exhaust gas is discharged through the exhaust port 121. The adsorbent 22 preferably adopts an activated carbon adsorption layer, which includes an adsorption material composed of honeycomb or granular activated carbon. These activated carbons have a high specific surface area and good adsorption performance, and can effectively adsorb harmful substances in the exhaust gas. The activated carbon has a fine pore structure and can provide a larger adsorption surface area, thereby enhancing the adsorption effect on harmful substances.

[0042] After being used for a period of time, a large amount of particulate matter is easily attached to the bottom surface of the dust filter 21, resulting in a decrease in the air permeability efficiency of the dust filter 21, affecting the exhaust gas adsorption effect. At this time, if there is water in the clean water chamber 13, the water pump 4 extracts the water in the clean water chamber 13 and transports it to the flushing component 5. The flushing component 5 is used to spray water from the top of the dust filter 21 to flush and clean the dust filter 21 to remove the dust particles on the filtering surface of the dust filter 21 to ensure the air permeability of the dust filter 21. The flushed water falls on the clean water component 3, and the dust particles are filtered out through the filter hole 321. The clean water flows into the clean water chamber 13, which is convenient for the water pump 4 to circulate and extract the clean water flow for the flushing component 5 to flush and clean the dust filter 21; if there is no water in the clean water chamber 13, the sealing plug 114 is opened, and water is injected through the water injection port 112. The water flows into the tower body 1, falls on the clean water component 3, and enters the clean water chamber 13 through the filter hole 321. After flushing is completed, the drain valve 115 can be opened to facilitate the water flow in the tower body 1 to carry the flushed dust particles and discharge them from the drain port 113 .

[0043] Compared with the prior art, the adsorption tower of the utility model integrates the dust filter 21 into the filter assembly 2, avoiding the arrangement outside the tower body 1, which is conducive to reducing the space occupied by the exhaust gas purification system and increasing the activity space of people. The water flow in the clean water chamber 13 is extracted by the water pump 4 and transported to the flushing assembly 5. The flushing assembly 5 is used to flush and clean the dust filter 21, ensuring the long-term dust filtering function of the dust filter 21, without the need for manual maintenance and replacement. After the flushed water falls on the clean water component 3, the particulate impurities carried in the water flow are filtered through the filter hole 321, so that the clean water flow returns to the clean water chamber 13, which is convenient for the water pump 4 to reuse, so as to repeatedly flush and clean the dust filter 21. Through the recycling of water resources, the water consumption is reduced. After the flushing is completed, the drain valve 115 is opened, and the flushing water and particulate matter can be discharged in time through the drain port 113.

[0044] like Figure 1-Figure 5 As shown, the tower body 1 of the utility model comprises a lower tower portion 11 with an open top and an upper tower portion 12 with an open bottom, an upper flange is provided at the circumferential outer edge of the top of the lower tower portion 11, an upper annular groove coaxial with the tower body 1 is provided on the upper flange, a lower annular groove coaxial with the tower body 1 is provided on the circumferential outer edge of the bottom of the upper tower portion 12 is provided, and a lower annular groove coaxial with the tower body 1 is provided on the lower flange, the upper flange and the lower flange are fixedly connected by threaded bolts 14 and nuts 15, the upper annular groove and the lower annular groove are combined to form an annular cavity, and a sealing ring 16 is filled in the annular cavity, and the sealing ring 16 is a rubber ring to ensure the sealed connection between the upper tower portion 12 and the lower tower portion 11.

[0045] The air inlet 111 and the water injection port 112 are both arranged on the circumferential side wall of the lower tower portion 11. The water injection port 112 is connected to a water injection pipe. The end of the water injection pipe away from the lower tower portion 11 is threadedly connected to a sealing plug 114. The lower tower portion 11 is a thick bottom structure. The drain port 113 is arranged on its bottom wall, and the drain port 113 extends to the bottom side wall of the lower tower portion 11; the exhaust port 121 is arranged at the top of the upper tower portion 12.

[0046] A further improvement is that the dust filter 21 includes a filter sponge 211; the dust filter 21 also includes a shaping frame 212 attached to the top surface and / or top surface of the filter sponge 211, the shaping frame 212 and the filter sponge 211 are fixedly connected to the circumferential inner wall of the tower body 1, and the filter surface of the filter sponge 211 is a corrugated surface or a conical surface.

[0047] Specifically, Figure 3-Figure 5 , Figure 8 and Fig. 9 As shown, the bottom and top surfaces of the filter sponge 211 are conical surfaces with the same axis and the same taper. This shape design can increase the filter area of ​​the filter sponge 211 to filter more dust particles and extend the cleaning cycle of the filter sponge 211. The circumferential outer edge of the filter sponge 211 is fixedly connected to the circumferential inner wall of the lower tower part 11. The filter sponge 211 is made of ordinary open-pore soft foam through a mesh treatment. The mesh treatment removes the original face film and wall film between the foam networks to obtain a main skeleton mesh structure. The filter sponge 211 has good elasticity, strong tensile strength, fast dust filtration speed, high dust filtration rate, and low airflow resistance. It has small force, good ventilation performance, good chemical properties such as drug resistance, and can be washed with water. The effect does not deteriorate after washing, so it is suitable for repeated flushing and cleaning; and a rigid shaping frame 212 is arranged on the top and bottom surfaces of the filter sponge 211. The shaping frame 212 is a mesh structure, and its circumferential outer edge is fixedly connected to the circumferential inner wall of the lower tower part 11, and the shaping frame 212 fits the filter sponge 211. In this way, a good shaping effect is achieved on the filter sponge 211, which avoids the filter sponge 211 being seriously deformed and damaged by the impact of the airflow below during dust filtering and the impact of the water flow above during cleaning.

[0048] A further improvement is that the water purification component 3 includes a guide tube 31 whose axis extends in the vertical direction, the inner diameter of the guide tube 31 gradually decreases from top to bottom, the top circumferential outer edge of the guide tube 31 is fixedly connected to the circumferential inner wall of the tower body 1, and the bottom is connected to the drain port 113; the water purification component 3 also includes a connecting tube 32 whose axis is parallel to the vertical direction and fixed between the bottom end of the guide tube 31 and the inner bottom wall of the tower body 1, the bottom of the connecting tube 32 is connected to the drain port 113, and the filter hole 321 is arranged on the side wall of the connecting tube 32; the filter hole 321 is covered with a filter cloth 322.

[0049] Specifically, Figure 3 , Figure 5 , Figure 8 and Fig. 9 As shown, the water purification part 3 mainly includes a guide tube 31 fixed to a connecting pipe 32 between the bottom end of the guide tube 31 and the inner bottom wall of the lower tower part 11, wherein the guide tube 31 is conical, so that when washing the filter sponge 211, water flows on the inner wall of the guide tube 31, drives the particles to flow downward along the inside, enters the inner side of the connecting pipe 32, and then is discharged from the drain port 113. The filter holes 321 are slender strips along the vertical direction, and the filter holes 321 are distributed in an annular array on the side wall of the connecting pipe 32, and the filter cloth 322 is cylindrical, and the circumferential outer edge of the filter cloth 322 is fixedly connected to the circumferential inner wall of the connecting pipe 32 and covers the filter holes 321. In this way, the filter cloth 322 can prevent the particles from entering the water purification chamber 13 from the filter holes 321 when the water flow carrying particles flows downward in the connecting pipe 32, thereby ensuring the cleanliness of the water flow in the water purification chamber 13.

[0050] A further improvement is that an observation port 116 is provided on the tower body 1, and an observation window 117 is provided on the observation port 116, and the top of the guide tube 31 is located between the top and the bottom of the observation window 117. Specifically, the observation port 116 is in a long strip shape and is located on the lower tower part 11. The water level in the lower tower part 11 can be conveniently observed through the observation window 117 on the observation port 116, so as to ensure that there is sufficient water in the lower tower part 11 to be pumped by the water pump 4 and transported to the flushing assembly 5 to flush and clean the dust filter 21, and at the same time, avoid excessive water level causing the liquid level to be higher than the air inlet 111, which affects the delivery of exhaust gas to the tower body 1.

[0051] A further improvement is that the flushing assembly 5 includes a flushing pipe 51 that rotates with the axis of the tower body 1 as the center line, one end of the flushing pipe 51 is connected to the input end of the water pump 4, and the other end is adjacent to the circumferential inner wall of the tower body 1, and the flushing pipe 51 is provided with flushing ports 511 distributed along its own circumferential intervals and connected to its own inner cavity, and the direction of the flushing port 511 has an angle with the vertical direction; a roller 52 is provided at one end of the flushing pipe 51 away from the axis of the tower body 1, and two positioning rings 122 distributed along the vertical direction are provided on the circumferential inner wall of the tower body 1, and the roller 52 rolls between the two positioning rings 122.

[0052] Specifically, Figure 3-Figure 7As shown, the flushing assembly 5 also includes a water pipe 53 and an adapter 54. The flushing pipe 51 is provided with two coaxial lines. One end of the water pipe 53 is fixedly connected to the circumferential inner wall of the upper tower portion 12 and is communicated with the output end of the water pump 4. The other end is coaxial with the upper tower portion 12 and extends downward. The circumferential outer edge of the end has a convex ring 531. The adapter 54 is a cylindrical structure coaxial with the upper tower portion 12. Its circumferential outer edge is sealed with the circumferential inner wall of the water pipe 53. An annular groove 541 is provided at the top. The convex ring 531 is coaxial with the annular groove 541. The two flushing ports 511 are arranged on the side walls of the flushing pipes 51, and the axis lines of the flushing pipes 51 and the flushing ports 511 are horizontal and perpendicular to each other. The flushing ports 511 on the two flushing pipes 51 are opposite. A roller 52 is arranged on one end of the flushing pipe 51 away from the adapter 54, and two convex rings 531 are distributed on the circumferential inner wall of the upper tower portion 12 along the vertical direction, and the roller 52 rolls between the two convex rings 531.

[0053] After adopting the above design, the water pump 4 draws clean water in the clean water chamber 13, and delivers it to the flushing pipe 51 through the water pipe 53 and the adapter 54. Then, after the water is ejected from the flushing port 511, it makes a horizontal motion and sprays downward on the dust filter 21, thereby flushing and cleaning the dust filter 21. Moreover, the ejected water reacts on the flushing pipe 51, so that the flushing pipe 51 rotates with the axis of the tower body 1 as the axis of rotation, and the flushing pipe 51 is stably supported by the roller 52 and the convex ring 531 to rotate, thereby changing the position where the water falls on the dust filter 21 after being ejected, thereby changing the flushing and cleaning position of the water, relying on the action of the water, expanding the flushing and cleaning range of the water, thereby improving the flushing and cleaning effect of the dust filter 21.

[0054] A further improvement is that the shaping frame 212 is an electric heating frame, and an electric heating wire is arranged inside the electric heating frame. With the above improvement, after the filter sponge 211 is flushed and cleaned, the electric heating wire inside the electric heating frame is energized, so that the temperature of the shaping frame 212 is increased, and the heat is transferred to the filter sponge 211, so that the water absorbed by the filter sponge 211 can evaporate quickly after being heated, thereby facilitating the filter sponge 211 to quickly restore its air permeability.

[0055] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
