It is widely used in industrial exhaust gas treatment as a device that uses chemicals and wet treatment methods to purify toxic and harmful exhaust gases.

[0003] The exhaust gas washing tower mainly uses its internal purification components to wash, adsorb and filter. However, after working for a long time, the effect of the purification components becomes worse and worse, and maintenance and replacement are inconvenient, which is not only time-consuming and labor-intensive, but also delays the subsequent purification of the exhaust gas. Utility Model Content

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Reference Figure 1, an exhaust gas purification tower that is easy to replace purification components, including an exhaust gas treatment mechanism and a filter assembly installed inside a tower body 1, the exhaust gas treatment mechanism including a support frame 7, a fixing frame 1 8, a packing layer 9, a placement frame 10, a water spray plate 11, a fixing frame 2 12 and a pipe 14, the fixing frame 2 12 and the support frame 7 are distributed from top to bottom, the placement frame 10 is two groups respectively installed on the fixing frame 2 12 and the bottom of the support frame 7, the water spray plate 11 is detachably installed in the placement frame 10, the pipe 14 is installed on the outer wall of the tower body 1, and is connected to the water spray plate 11 through the pipe, the fixing frame 1 8 is arranged in multiple arrangements and is installed under a corresponding group of water spray plates 11, and the packing layer 9 is detachably embedded and installed between two adjacent fixing frames 1 8;

[0022] The filter assembly includes a support plate 4, a filter plate 5 and a baffle 6. The support plate 4 is arranged obliquely at the lower end of the tower body 1. The filter plate 5 is detachably mounted on the support plate 4. The baffle 6 is fitted to the inner wall of the tower body 1 and is located at the lowest end of the support plate 4.

[0023] The washing liquid is input from 14 into the water spray plate 11 through an external spray pump, and is sprayed out through the water spray plate 11. Then, the exhaust gas enters the tower body 1 from the air inlet 3. The exhaust gas first passes through a group of packing layers 9 located below for filtration. The exhaust gas that passes through the packing layer 9 is then washed by the washing liquid sprayed by the water spray plate 11. The washed exhaust gas passes through a group of packing layers 9 located above and is filtered again by a group of water spray plates 11 above. The purified exhaust gas passes through the demisting layer 13, and the gas is dried by the demisting layer 13. The exhaust fan 2 helps the gas to be discharged from the tower body 1 faster, thus completing the exhaust gas treatment.

[0024] The waste liquid after washing the waste gas will flow onto the support plate 4, and the waste liquid will flow to the filter plate 5 along the slope of the support plate 4. After being filtered by the filter plate 5, it will finally flow to the bottom of the tower body 1. When cleaning and replacing the filter plate 5 later, you only need to remove the filter plate 5 from the tower body 1 and then replace it.

[0025] The middle part of the support frame 7 is hollow so that the exhaust gas can pass through the support frame 7 normally and out of the packing layer 9 and be filtered; before the gas passes through the packing layer 9, it will pass through the water spray plate 11 below. Because the two adjacent water spray plates 11 are arranged in an "eight" shape, the exhaust gas will be washed more effectively during its rising process and filtered and adsorbed by the packing layer 9.

[0026] Three demisting layers 13 are embedded in the fixing frame 12 and correspond one to one between the two adjacent water spray plates 11 below it; an exhaust fan 2 is also installed on the top of the tower body 1. After the gas is purified, it passes through the demisting layer 13 for drying, and is subsequently quickly discharged with the assistance of the exhaust fan 2.

[0027] On one side outer wall of the tower body 1, openings corresponding to the filter plate 5, the packing layer 9, the water spray plate 11 and the demisting layer 13 are provided. The above openings are detachably sealed by a sealing plate so that the filter plate 5, the packing layer 9, the water spray plate 11 and the demisting layer 13 can be maintained and replaced. Because the exhaust gas washing tower will gradually reduce the effect of the purification components after a long period of use, it needs timely maintenance and replacement. Moreover, after a long period of use, the water outlet of the water spray plate 11 is also easily contaminated and also needs to be cleaned in time, otherwise it will seriously affect the normal purification treatment of the exhaust gas.

[0028] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
