DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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] Example 1

[0027] A waste gas treatment equipment for the production of hazardous chemicals, such as Figure 1-6 As shown, it includes a base 1 and a cylinder 2; a plurality of bases 1 are fixedly connected to the cylinder 2;

[0028] It also includes a rectangular plate 3, a rotating plate 101, a partition 102, a motor 103, a sponge ring 104, an adsorption resin 105, a mounting frame 106, an air inlet pipe 107, a fixed plate 108, an arc plate 109 and a cleaning component; the cylinder 2 is provided with a plurality of exhaust holes 21; the cylinder 2 is rotatably connected to the rotating plate 101; the rotating plate 101 is fixedly connected to two partitions 102, and the partitions 102 are symmetrically distributed in the cylinder 2, and the positions of the partitions 102 and the rectangular plate 3 correspond; two symmetrically distributed partitions 102 and two sponge groups symmetrically distributed front and back are arranged in the cylinder 2; the sponge group is composed of a sponge ring 104 with a large diameter and a sponge ring 104 with a small diameter, and the sponge ring 104 is made of high temperature resistant material; two sponge rings 104 with different diameters are distributed inside and outside and have the same center; a semicircular ring space is formed between the two sponge rings 104, and the semicircular ring space The space is filled with adsorption resin 105, and the ends of the two sponge groups are fixedly connected to the partition 102; the cylinder 2 is fixedly connected to two rectangular plates 3, and the rectangular plates 3 are located inside the cylinder 2, and the cylinder 2 and the outer sponge ring 104 form an annular space, and the rectangular plates 3 are located in the space; the cylinder 2 is bolted to the motor 103, and the output shaft of the motor 103 is fixedly connected to the rotating plate 101; the cylinder 2 is fixedly connected to the mounting frame 106; the mounting frame 106 is fixedly connected to the air intake pipe 107; the air intake pipe 107 is fixedly connected to a fixing plate 108, and the fixing plate 108 is in contact with the inner sponge ring 104; the fixing plate 108 is fixedly connected to a semicircular arc plate 109, and the arc plate 109 is in contact with the inner sponge ring 104, and the arc plate 109 and the rear sponge group together form an air intake space 1091; the cylinder 2 is connected to a cleaning component for cleaning the adsorption resin 105.

[0029] The cleaning component includes a connecting tube 1010, a connecting plate 1011 and a hollow tube 1012; a temporary storage groove 1021 is opened on the upper side of the rotating plate 101; a plurality of connecting tubes 1010 are connected to the lower side of the cylinder 2, and the connecting tubes 1010 are located directly below the adsorption resin 105; the mounting frame 106 is connected to the connecting plate 1011, and the connecting plate 1011 is connected to the sponge ring 104; the connecting plate 1011 is fixedly connected to a plurality of hollow tubes 1012, and the hollow tubes 1012 are located above between the two sponge rings 104 of the sponge group.

[0030] The front portion of the curved plate 109 is rough, while the rear portion of the curved plate 109 is smooth.

[0031] When in use, first connect the external exhaust gas discharge pipe to the air intake pipe 107, connect the first external pump to the connecting pipe 1010, connect the second external pump to the hollow tube 1012, and pour the adsorption resin 105 between the two sponge rings 104 of each sponge group, then control the external exhaust gas discharge pipe to pass the exhaust gas through the air intake pipe 107 into the air intake space 1091 between the arc plate 109 and the inner sponge ring 104 of the rear sponge group, and then the exhaust gas enters the rear adsorption resin 105 through the inner sponge ring 104, and the exhaust gas adsorbed and purified by the adsorption resin 105 and filtered by the sponge ring 104 is finally discharged from the outer sponge ring 104 of the rear sponge group into the cylinder 2, and finally discharged from the exhaust hole 21, and the rectangular plate 3 divides the annular space formed by the cylinder 2 and the sponge ring 104 into two halves, so the exhausted gas will not flow to the front sponge group area.

[0032] After a predetermined treatment period, the adsorption resin 105 at the rear is saturated with adsorption, and the adsorption and purification effect of the exhaust gas is reduced. At this time, the control motor 103 is started, and the rotating plate 101 drives the partition 102 to rotate through the output shaft of the motor 103. The partition 102 drives the two sponge groups to rotate 180 degrees, so that the clean sponge group at the front rotates to the rear side to participate in the adsorption and purification of the exhaust gas, and the used sponge group at the rear rotates to the front side for cleaning and regeneration. The used sponge group at the rear produces relative movement with the front of the arc plate 109 during rotation, and then the rough arc plate 109 at the front scrapes off the oil on the sponge ring 104 on the used sponge group at the rear. The scraped oil and the oil remaining on the arc plate 109 flow into the temporary storage tank 1021, and are finally collected through the collection pipe 205. Since the rear of the arc plate 109 is smoothly arranged, it is convenient for the oil attached to the rear of the arc plate 109 to flow downward.

[0033] Next, the first external pump is controlled to transport the high-temperature steam upward through the connecting pipe 1010 to between the two sponge rings 104 to be cleaned at the front, and then the high-temperature steam passes upward through the adsorption resin 105, and then the harmful gas molecules adsorbed in the adsorption resin 105 are separated from the adsorption resin 105 under the steam, and move upward with the steam, and finally discharged from the hollow tube 1012, and then the adsorption resin 105 is cleaned and regenerated. Compared with the existing resin purification equipment with regeneration function, this equipment is small in size, simple in structure and efficient, and is suitable for low-cost use by small manufacturers. When the adsorption resin 105 is cleaned and regenerated, the exhaust gas can continue to be purified by the sponge group at the rear.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1 and Figure 2-6As shown, it also includes a pressure plate 202 and a limiting rod 203 located on the upper side of two sponge rings 104 of a sponge group. The pressure plate 202 is fixedly connected, and the pressure plate 202 is arranged in a semicircular ring shape, and the shape of the pressure plate 202 corresponds to the sponge ring 104; the fixed plate 108 is fixedly connected to a plurality of spaced limiting rods 203, and the limiting rods 203 are fixedly connected to the cylinder 2, and the limiting rods 203 are in contact with the inner arc surface of the inner sponge ring 104.

[0036] The surface of the limiting rod 203 is rough, so that the sponge ring 104 moves relative to the limiting rod 203 when rotating, and the limiting rod 203 scrapes off the oil stains remaining on the sponge ring 104 .

[0037] When the sponge group is replaced, the sponge ring 104 and the limiting rod 203 move relative to each other, and then a plurality of spaced limiting rods 203 scrape off the oil stains on the sponge ring 104. Compared with the scraping of the oil stains on the sponge ring 104 by the arc plate 109, since the position of the arc plate 109 when scraping the sponge ring 104 is the edge area of ​​the arc plate 109, too much oil stains will remain on the edge of the arc plate 109, reducing the scraping efficiency of the oil stains. The plurality of spaced limiting rods 203 can disperse the oil stains, reduce the amount of oil stains on each limiting rod 203, and improve the cleaning efficiency of the oil stains.

[0038] Example 3

[0039] On the basis of Example 2, Figure 1 and Figure 4-5 As shown, an annular airbag 301 is also included; the annular airbag 301 is fixedly connected to the inner side of the cylinder 2, and the annular airbag 301 is located outside the sponge ring 104.

[0040] It also includes punctures 302; a plurality of punctures 302 are fixedly connected to the inner side of the annular airbag 301.

[0041] It also includes an electric push rod 303; a connecting plate 1011 is slidably connected to the mounting frame 106; the connecting plate 1011 is slidably connected to the sponge ring 104; the mounting frame 106 is bolted to the electric push rod 303, and the telescopic end of the electric push rod 303 is fixedly connected to the connecting plate 1011.

[0042] The piercing member 302 is made of a high temperature resistant material to prevent deformation of the piercing member 302 when the piercing member 302 pierces the adsorption resin 105 at a high temperature.

[0043] It also includes a sealing ring 304 ; the cylinder 2 is rotatably connected to the sealing ring 304 , and the sealing ring 304 is fixedly connected to the sponge ring 104 .

[0044] First, connect the external air pump to the annular airbag 301. When the steam moves upward between the two sponge rings 104 of the front sponge group and takes out the harmful gas molecules adsorbed on the adsorption resin 105, part of the steam and harmful gases will escape from the sponge ring 104 on the outside of the front sponge group and cannot be collected by the hollow tube 1012. Therefore, before the steam is introduced between the two sponge rings 104 of the front sponge group, the external air pump is controlled to inflate the annular airbag 301, and the inner side of the annular airbag 301 expands inward until the inner side of the annular airbag 301 contacts the sponge ring 104 on the outside of the front sponge group, and then the annular airbag 301 limits the sponge ring 104 to prevent steam and harmful gases from escaping from the sponge ring 104 on the outside of the front sponge group, resulting in incomplete waste gas treatment.

[0045] When the waste gas passes through the filter of the sponge ring 104 and enters the adsorption resin 105, since the sponge ring 104 cannot completely filter the oil in the waste gas, some oil will also exist in the adsorption resin 105. Therefore, after the used sponge group is rotated to the front, the steam first takes out the harmful gas molecules in the adsorption resin 105, and then the second external pump is controlled to start, and the ethanol solution is sprayed into the area between the two sponge rings 104 through the hollow tube 1012, and then the ethanol solution is used to absorb the oil between the two sponge rings 104. The attached resin 105 is eluted, and the elution liquid flows downward into the connecting tube 1010 for collection. During the elution process, the external air pump is controlled to reciprocately inflate and exhaust the annular airbag 301, so that the inner side of the annular airbag 301 moves radially back and forth, and then the inner side of the annular airbag 301 drives the pricking 302 to move, and then the pricking 302 reciprocates to poke the sponge ring 104 and the adsorption resin 105, and turns the adsorption resin 105, thereby improving the elution efficiency of the adsorption resin 105 by the ethanol solution.

[0046] Since the gap between the holes of the sponge ring 104 is relatively small, it is difficult for the tiny probing stick 302 to penetrate the sponge ring 104. Therefore, before the probing stick 302 reciprocates the sponge ring 104 and the adsorption resin 105, the electric push rod 303 is controlled to make the connecting plate 1011 pull the upper sides of the two sponge rings 104 to move upward, so that the sponge ring 104 is stretched, thereby enlarging the gap between the holes of the sponge ring 104, making it easier for the probing stick 302 to penetrate the sponge ring 104, thereby improving the poking efficiency of the adsorption resin 105.

[0047] When the sponge ring 104 is stretched, a gap is generated between it and the cylinder 2, and the exhaust gas can easily escape from the gap. Therefore, the cylinder 2 is sealed by the sealing ring 304. When the sponge ring 104 rotates, it drives the sealing ring 304 to rotate, thereby maintaining a sealed state between the sponge ring 104 and the cylinder 2.

[0048] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
