Description

Technical Field

[0001] The utility model relates to the technical field of gas purification and processing equipment, in particular to a wastewater purification washing tower. Background Art

[0002] The scrubber is a new type of gas purification equipment, which is improved on the basis of the floating packing layer gas purifier. It is widely used in pre-treatment of industrial waste gas purification, dust removal, etc., and has a good purification effect.

[0003] Existing wastewater purification washing towers are in use, but during the process of waste gas purification, it is usually necessary to transport industrial waste gas to the washing tower. Since the waste gas contains a lot of dust and other impurities, when the dust and other impurities are transported to the washing tower for treatment together with the waste gas, as the treatment proceeds, part of the treated dust will accumulate in the washing tower. Over time, a lot of dirt will accumulate in the washing tower body. The dirt contains various impurities, which can easily cause corrosion and damage to the washing tower, reducing the service life of the washing tower. At the same time, excessive accumulation of dirt can easily clog various pipes, resulting in a decrease in the washing effect. The current washing tower mostly requires manual regular cleaning for the treatment of dirt, which is not only time-consuming and labor-intensive, but also requires the washing tower to be closed during cleaning, affecting the normal use of the washing tower body.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 , the utility model provides a technical solution:

[0028] A wastewater purification washing tower comprises an integrally connected water tank 1, a sprinkler main pipe 2, a dust suppression pipe 3, an exhaust gas inlet 4, and a purification pipe 5, a filter screen 6 coated with activated carbon inside the purification pipe 5, and a water inlet pipe port is also provided at one end of the water tank 1, the filter screen 6 is movably provided on the inner wall of the purification pipe 5, a circular groove 61 is provided in the center part of the filter screen 6, a drain pipe 7 connected to the inside of the water tank 1 is provided on the outer surface of the water tank 1, a drainage mechanism 8 connected to the drainage pipe 7 is also provided inside the water tank 1, and the drainage mechanism 8 is used in conjunction with the filter screen 6 and the drainage pipe 7.

[0029] By adopting the above technical solution, when the washing tower is working, the water in the water tank 1 will first be transported to the inside of the dust reduction pipe 3 through the sprinkler pipe 2 and then sprayed. The sprinkler pipe 2 here is equipped with a pump outside the water tank, and the part extending to the dust reduction pipe 3 is provided with a nozzle. The exhaust gas enters the dust reduction pipe 3 from the exhaust gas inlet 4, contacts with the sprayed water and falls on the filter 6 in the purification pipe 5 to be filtered, and then is adsorbed by the activated carbon on the filter 6 to achieve the function of wastewater purification. After the filter 6 absorbs dirt and dust, the weight of the filter 6 will increase, and then it will fall due to gravity, thereby working with the drainage mechanism 8 to empty the internal aqueous solution through the drainage pipe 7, and then enter the new aqueous solution through the water inlet pipe at one end of the water tank 1, which can effectively reduce the situation where the effect of the washing tower is reduced after the aqueous solution absorbs harmful substances in the exhaust gas to saturation.

[0030] Specifically, Figures 1 to 4As shown, the bottom of the filter 6 is fixedly connected with a vertical downward connecting rod 81, and the inner wall of the water tank 1 is fixedly installed with a rectangular block 82, and the rectangular block 82 and the connecting rod 81 cooperate with each other. A drain port 83 connected to the drain pipe 7 is opened inside the rectangular block 82.

[0031] The rectangular block 82 is provided with a first slide groove 821, a second slide groove 822 and a third slide groove 823 which are interconnected. The first slide groove 821 is provided with a water blocking ring 824 for sliding inside. The third slide groove 823 is provided with a movable rod 825 for sliding inside. The outer surface of the movable rod 825 is sleeved with a first spring 826. One end of the first spring 826 is fixedly installed on the inner wall of the first slide groove 821, and the other end is fixedly connected to the water blocking ring 824. The movable rod 825 is fixedly connected to the water blocking ring 824. The second slide groove 822 is provided with a slider 827 for use with the connecting rod 81 for movement inside. The top of the inner wall of the second slide groove 822 is fixedly installed with a second spring 828, and the bottom of the second spring 828 is fixedly connected to a limiting ball 829, and the limiting ball 829 and the slider 827 are used in conjunction with each other.

[0032] The diameter of the water blocking ring 824 is greater than the diameter of the drain port 83 and one end of the water blocking ring 824 close to the drain port 83 is made of rubber. The first slide groove 821 is connected to the outside.

[0033] The bottom of the movable rod 825 is set at an angle, and the slider 827 can be divided into two parts, a cylindrical part and a triangular part. The top of the cylindrical part is set at an angle and is used in conjunction with the limiting ball 829. The longest side of the triangular part is in contact with the connecting rod 81, and after the slider 827 enters the second sliding groove 822, the triangular part can support the connecting rod 81 and prevent it from falling, and the elastic force of the first spring 826 is greater than the elastic force of the second spring 828.

[0034] By adopting the above technical solution, when the drain pipe 7 is working, the filter screen 6 will first drop in height due to the increased weight after filtering and absorbing dirt, and at this time, the connecting rod 81 will be pressed down. Due to the action of the connecting rod 81 and the slider 827, the inclined end of the connecting rod 81 contacts one end of the triangular part of the slider 827, thereby pushing the slider 827 to move with the water blocking ring 824. However, due to the existence of the second spring 828 and the limiting ball 829, if the weight of the filter screen 6 does not exceed the elastic force of the first spring 826 and the second spring 828, the slider 827 will not move. When the total elastic force exceeds this, the second spring 828 will The spring 828 contracts, and the limiting ball 829 enters the top of the inner wall of the second slide groove 822. Then the slider 827, the water blocking ring 824 and the movable rod 825 move together, and the movable rod 825 enters the third slide groove 823. At the same time, the first spring 826 contracts. When the connection between the cylindrical part and the triangular part of the slider 827 passes through the limiting ball 829 part, the second spring 828 rebounds and pushes the slider 827 and the water blocking ring 824 along the triangular part into the first slide groove 821 and the second slide groove 822, thereby completely separating the water blocking ring 824 from the drain outlet 83 to achieve the drainage effect.

[0035] Specifically, Figure 2 and Figure 5 As shown, a scraping mechanism 9 for cleaning the surface of the filter 6 is provided at the bottom of the filter 6, and the scraping mechanism 9 includes a siphon tube 91 fixedly arranged on the inner wall of the circular groove 61, a turbine 93 is fixedly installed on the inner wall of the siphon tube 91, and circular holes 96 are equidistantly provided on the bottom circumference of the inner wall of the siphon tube 91, a liquid flow groove 92 is provided on the inner wall of the siphon tube 91, and liquid can be discharged from the liquid flow groove 92 through the circular hole 96, and a support rod 94 is provided in the liquid flow groove 92, and the support rod 94 passes through the center of the turbine 93 and is fixedly connected to the turbine 93.

[0036] After the drainage mechanism 8 is working, the height to which the filter screen 6 descends can keep the circular hole 96 and the drainage pipe 7 at the same height.

[0037] The turbine 93 is disposed at the upper end of the circular hole 96 , and the direction of the water flow generated by the turbine 93 is downward.

[0038] By adopting the above technical scheme, after the drainage mechanism 8 works and drains the aqueous solution inside the water tank to the height of the drainage port 83, the aqueous solution originally in the liquid flow groove 92 will be discharged from the circular hole 96. When the aqueous solution is discharged, it will drive the turbine 93 to rotate. When the turbine 93 rotates, it will drive the scraper 95 to rotate through the support rod 94, thereby scraping off the dirt on the filter screen 6. After the dirt on the filter screen 6 is scraped off, the weight of the filter screen 6 decreases. At this time, the first spring 826 rebounds, pushing the water blocking ring 824, the movable rod 825 and the slider 827 to move outward in the first slide groove 821, the second slide groove 822 and the third slide groove 823. During the outward movement of the slider 827, due to the inclined surface of the triangular part, it will gradually push the connecting rod 81 upward, thereby pushing the filter screen 6 to reset. At the same time, the water blocking ring 824 blocks the drainage port 83 again to achieve a closed effect. At this time, new aqueous solution can enter through the water inlet pipe at one end of the water tank 1, thereby achieving the effect of replacing the internal nearly saturated aqueous solution.

[0039] Working principle: When the washing tower is working, first, the water in the water tank 1 will be transported to the inside of the dust removal pipe 3 through the sprinkler pipe 2 and then sprayed. The sprinkler pipe 2 here is equipped with a pump outside the water tank, and the part extending to the dust removal pipe 3 is provided with a nozzle. The exhaust gas enters the dust removal pipe 3 from the exhaust gas inlet 4, contacts with the sprayed water and falls on the filter 6 in the purification pipe 5 to be filtered, and then is adsorbed by the activated carbon on the filter 6 to achieve the function of wastewater purification. After the filter 6 absorbs dirt and dust, the weight of the filter 6 will increase, and then it will fall due to gravity, thereby working with the drainage mechanism 8, emptying the internal aqueous solution through the drainage pipe 7, and then entering the new aqueous solution through the water inlet at one end of the water tank 1, which can effectively reduce the situation where the effect of the washing tower decreases after the aqueous solution absorbs harmful substances in the exhaust gas to saturation;

[0040] When the drainage mechanism 8 works and drains the aqueous solution inside the water tank to the height of the drainage port 83, the aqueous solution originally in the liquid flow groove 92 will be discharged from the circular hole 96. When the aqueous solution is discharged, it will drive the turbine 93 to rotate. When the turbine 93 rotates, it will drive the scraper 95 to rotate through the support rod 94, thereby scraping off the dirt on the filter screen 6, thereby ensuring that the filter screen 6 is not blocked by dirt and can still maintain a good filtering effect.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
