Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, and particularly relates to an air inlet diversion structure of a spray tower for chemical raw material production. Background Technique

[0002] Spray towers are mainly used to treat industrial waste gas. Through the full contact between the waste gas and the liquid, and by utilizing the solubility or chemical reaction of the waste gas in the liquid, the concentration of the waste gas is reduced. Its working principle depends on dry spray nozzles. Through the spraying of the spraying medium, the harmful substances in the waste gas are absorbed or neutralized;

[0003] For example, the Chinese utility model patent disclosed in the existing publication number CN214051105U: a spray tower, including a spray tower body, and an air inlet is provided at the lower part of the spray tower body, and an exhaust port is provided at the top of the spray tower body. A purified liquid collection box is provided at the bottom of the spray tower body. An oil separation box and a purified liquid box are arranged in parallel on one side of the purified liquid collection box. The purified liquid collection box is communicated with the oil separation box through a U-shaped pipe, and the oil separation box is communicated with the purified liquid box through an oil filter. Therefore, when the waste gas is treated in this application, the waste gas is directly introduced into the spray tower body through the air inlet pipe and the air inlet. After a large amount of gas directly enters the spray tower body, the rapid influx of a large amount of waste gas may cause insufficient contact time between the gas and the spraying medium, and failure to mix and react fully, thus reducing the removal efficiency of harmful substances. Moreover, a large amount of waste gas entering the spray tower will reduce the flow pressure of the waste gas entering the spray tower, that is, the low-pressure state will affect the atomization effect of the spraying medium, reduce the contact area between the gas and the spray droplets, and further limit the occurrence of the neutralization reaction. Content of the Utility Model

[0004] The purpose of the utility model is to provide an air inlet diversion structure of a spray tower for chemical raw material production, which can effectively solve the problem in the background technique that the existing spray tower has short contact time with spray droplets and insufficient neutralization reaction due to the direct entry of waste gas.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An air inlet diversion structure for a spray tower used in chemical raw material production, including a spray tower body. An air outlet pipe is fixedly installed at the top of the spray tower body.

[0010] Optionally, a second fixing seat is fixedly installed on the outside of the jet head. A spiral thread is fixedly installed on the jet head on one side of the second fixing seat, and the jet head is threadedly connected to the corresponding screw groove through the spiral thread.

[0011] Optionally, a plurality of drain holes are opened at the bottom of the elbow;

[0012] Based on this, by opening a plurality of drain holes at the bottom of the elbow, part of the water droplets entering the elbow can be discharged, preventing them from remaining in the elbow or the side pipe.

[0013] Optionally, a bottom plate is fixedly installed at the bottom of the elbow on one side of the drain holes, and a plurality of through holes are opened in the bottom plate at a position below the drain holes.

[0015] Optionally, a compression spring is sleeved on the plug rod between the sealing gasket and the bottom plate;

[0016] Based on this, by inserting and installing the sealing gasket in the drain hole, the water droplets entering the elbow can be discharged through the drain hole when the equipment is not running. When the air is introduced, the sealing gasket can be pressed down by the wind pressure to close the drain hole, ensuring that the gas enters the spray tower body at a high speed.

[0017] The working principle and beneficial effects of the present utility model are as follows:

[0032] Referring to Figures 1-6 , which is the first embodiment of the present utility model, a gas inlet diversion structure for a spray tower used in chemical raw material production is proposed, including a spray tower body 1. An outlet pipe 2 is fixedly installed at the top of the spray tower body 1. A water inlet pipe 3 is fixedly installed outside the spray tower body 1, and the water inlet pipe 3 is communicated with a spray pipe inside the spray tower body 1. The spray tower body 1 located below the water inlet pipe 3 is also fixedly installed with a water outlet pipe 4 and an air inlet pipe 5 respectively. A gas distribution mechanism 6 is arranged on one side of the air inlet pipe 5. The gas distribution mechanism 6 includes a shunt pipe 7. A plurality of side pipes 8 are fixedly installed outside the shunt pipe 7. A plurality of jet mechanisms 9 are arranged outside the side pipes 8. The jet mechanism 9 includes a jet head 10.

[0034] Embodiment 2:
