Description

Technical Field

[0001] The utility model relates to the field of nitrate production equipment, in particular to a nitrate conversion device. Background Art

[0002] Tail water containing nitrates is widely distributed in industries such as metal processing, electroplating, nuclear industry and food processing. Direct discharge of nitrate tail water will cause excessive salt content in water bodies, eutrophication, odor and other phenomena. Nitrates penetrate into the soil and enter the human body through plant absorption. Although nitrates are harmless to the human body, they are easily reduced to nitrites in the human body. When nitrites are absorbed in large quantities by the blood, their oxygen-carrying capacity will be inhibited, affecting the normal oxygen supply to tissues.

[0024] When in use, the tail water after the nitrate conversion process enters the water pump 12 through the tail water discharge pipe 11, and the water pump 12 sends the tail water into the tail water inlet pipe 13, and then introduces it into the tail water treatment tank 2. The through hole 1702 on the filter shell 1701 is designed so that the tail water can pass through the filter shell 1701 evenly. At the same time, the filter shell 1701 itself can block a part of the larger particles of impurities. When the tail water passes through the resin filter 18, the resin particles can adsorb and remove nitrates and other heavy metal ions in the water, such as calcium, magnesium, etc., so as to achieve the effect of softening the water quality. The exchange effect of the resin filter 18 can also remove organic substances such as ammonia in the water, further improving the quality of the tail water. The setting of the first stirring component helps to enhance the contact effect between the tail water and the resin filter 18, and improve the removal efficiency of nitrates.

[0025] The first stirring assembly includes a first driving motor 21, a first stirring shaft 19 and a plurality of first stirring blades 20. The first driving motor 21 is fixedly installed at the bottom center of the tailwater treatment tank 2. The output shaft of the first driving motor 21 is fixedly connected to one end of the first stirring shaft 19. The plurality of first stirring blades 20 are equidistantly installed on the surrounding surface of the first stirring shaft 19. The close connection between the output shaft of the first driving motor 21 and the first stirring shaft 19 reduces energy loss, improves stirring efficiency, and thus improves the nitrate removal effect. The design of the first stirring blades 20 can also help break the agglomeration of suspended matter and particulate matter in the tailwater, so that they are better dispersed in the tailwater, which is beneficial to the adsorption and exchange of the resin filter 18.

Sealing plugs are installed on the surfaces of the liquid medicine pouring port 6 and the nitrate pouring port 7. The liquid medicine pouring port 6 and the nitrate pouring port 7 opened at the top facilitate the feeding process of the operator, and the sealing plug can ensure the tightness of the liquid medicine pouring port 6 and the nitrate pouring port 7 to prevent harmful gases or liquids from leaking from the pouring port, posing a threat to the environment and the health of the operators.

The main function of the thermal insulation gasket 302 is to reduce heat loss and improve heating efficiency. It can effectively prevent the heat generated by the heating tube 301 from being transferred to the bottom of the heating box 3, thereby reducing energy waste. At the same time, the thermal insulation gasket 302 can also protect the bottom of the heating box 3 from being affected by high temperature, thereby extending the service life of the heating box 3.

The air outlet end of the air pump 9 is connected to a hot air outlet pipe 10. One end of the hot air outlet pipe 10 passes through the top of the absorption tower 1 and extends into the cavity of the absorption tower 1. The air pump 9 inhales the hot air generated in the heating box 3 through the air outlet, and directly transports it to the cavity of the absorption tower 1 through the hot air outlet pipe 10, which can ensure that the heat directly acts on the tail water and treatment agent in the absorption tower 1, thereby accelerating the chemical reaction and physical process and improving the efficiency of tail water treatment.

[0029] A second stirring assembly is arranged inside the absorption tower 1, and the second stirring assembly includes a second driving motor 8 and a second stirring shaft 801.
