Description

Technical Field

[0001] The utility model relates to the technical field of waste gas spray towers, in particular to waste gas spray tower equipment used for waste gas treatment. Background Art

[0002] The spray tower exists as a treatment equipment for environmental waste gas treatment. Its working principle is that when dust-containing waste gas or oil-containing waste gas passes through the spray tower body, liquid medium is sprayed out from the appropriate position inside the tower body. Some are alkali solutions and some are sulfuric acid solutions. In some industrial production processes, a large amount of waste gas will be discharged. In the process of waste gas emission, in order to ensure that the waste gas meets the emission standards, a spray tower is generally used to treat the waste gas.

[0003] In the actual use of the spray tower equipment currently used in the field of waste gas treatment, the spraying treatment liquid rate is often fixed. When the exhaust gas intake rate in the intake pipe connected to the spray tower is too high, the exhaust gas treatment liquid often cannot fully contact the exhaust gas, and the exhaust gas cannot be fully treated, which leads to poor exhaust gas treatment effect of the exhaust gas spray tower equipment.

[0025] Example

[0026] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a waste gas spray tower device for waste gas treatment, including: a spray tower body unit 100, a waste gas speed regulation unit 200 and a circulating liquid replenishment unit 300.

[0027] The spray tower unit 100 includes a tower body 101 and an air inlet pipe 102 fixedly installed at the lower end of the side wall of the tower body 101. The top of the tower body 101 is also fixedly connected to an exhaust pipe 103. The top of the exhaust pipe 103 is fixedly connected to multiple groups of evenly distributed support rods. The tops of the multiple groups of support rods are commonly fixedly connected to a rain cover 104.

The spray tower unit 100 also includes a spray assembly 106 for spraying waste gas treatment liquid. A transparent observation window 105 is inlaid and installed on the side wall of the tower body 101. The height of the transparent observation window 105 is one-quarter to one-third of the height of the tower body 101. The setting of the transparent observation window 105 is convenient for staff to observe the spraying effect of the waste gas treatment liquid and the waste gas in the tower body 101.

[0028] Secondly, the exhaust gas speed regulating unit 200 includes an intercepting plate 201 fixedly mounted on the inner wall of the intake pipe 102 and a tapered opening formed on the intercepting plate 201, a corresponding tapered plug 202 is arranged in the tapered opening, a support plate 208 is fixedly mounted in the intake pipe 102, a corresponding threaded rod 203 is rotatably connected to the support plate 208, an adjusting rod 204 is rotatably connected to the side wall of the intake pipe 102, the adjusting rod 204 is inserted into the intake pipe 102 and fixedly connected to a first bevel gear 205, an end of the threaded rod 203 away from the tapered plug 202 is fixedly connected to a second bevel gear 206 meshing with the first bevel gear 205, and the first bevel gear 206 meshes with the first bevel gear 205. 05 and the second bevel gear 206 are both made of manganese steel, and the first bevel gear 205 and the second bevel gear 206 are both provided with evenly distributed anti-skid patterns. The first bevel gear 205 and the second bevel gear 206 made of manganese steel have good wear resistance and good extrusion capacity, which prolongs the service life of the two. The setting of the anti-skid patterns improves the meshing stability of the first bevel gear 205 and the second bevel gear 206. A threaded block 207 is threadedly connected to the threaded rod 203. The threaded block 207 is fixedly connected to the conical plug 202 by multiple groups of evenly distributed connecting rods 209, and multiple connecting rods 209 are all set through the support plate 208.

By using the recovery box 301, the circulation pipe 303 and the circulation pump 304, the waste liquid generated by spraying can be recycled and reused, thereby improving the utilization rate of the waste gas treatment liquid.

[0031] During use, when the exhaust gas entering the intake pipe 102 has a too high rate, the adjusting rod 204 is rotated in the forward direction, and the first bevel gear 205 fixedly connected thereto drives the threaded rod 203 to rotate via the second bevel gear 206, and the threaded block 207 threadedly connected to the threaded rod 203 pushes the tapered plug 202 toward the tapered mouth via the connecting rod 209, thereby reducing the gap between the tapered mouth and the tapered plug 202, thereby limiting the intake rate of the intake pipe 102, and effectively solving the problem that the exhaust gas treatment liquid cannot fully contact with the exhaust gas due to the excessive intake rate, and the spray tower equipment has a poor exhaust gas treatment effect.
