Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a deammoniation device for high-ammonia-nitrogen and low-COD waste gas with high efficiency. Background Technique

[0002] For the treatment of waste gas with high ammonia-nitrogen and low COD, the main concern is how to effectively remove ammonia-nitrogen in the waste gas. Such waste gas may come from fields such as chemical production, waste incineration, and agricultural activities. Ammonia-nitrogen is a common air pollutant, which is not only harmful to human health but also causes environmental pollution problems such as the formation of acid rain.

[0003] When treating high-ammonia waste gas, the spray method and the adsorption method are mostly used. The spray method uses the high water solubility of ammonia to treat ammonia and forms ammonia-containing wastewater. After the wastewater is formed, it still needs to be treated before it can be discharged. And if there are impurities in the waste gas during the waste gas treatment process, it is extremely easy to affect the spraying effect of the spray tower. For this reason, we propose a deammoniation device for high-ammonia-nitrogen and low-COD waste gas with high efficiency. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-5 , the present invention provides a technical solution: an ammonia removal device for high-ammonia-nitrogen and low-COD waste gas, including a spray tower 1 and a chemical treatment mechanism 5.

[0020] Among them, by setting the spray tower 1, the treatment water and the waste gas can be combined during waste gas treatment to dissolve and capture ammonia nitrogen to form ammonia-containing wastewater. Subsequently, the water supply mechanism 6 is used to transport the ammonia-containing wastewater into the chemical treatment mechanism 5 for rapid ammonia removal treatment. Such a waste gas treatment method is convenient for treating waste gas with high ammonia nitrogen content, and has strong treatment continuity and higher treatment efficiency. Before waste gas treatment, the pre-treatment mechanism 4 can preliminarily filter impurities in the waste gas to prevent the waste gas from affecting the spraying efficiency of the spray tower during treatment.

[0021] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5, the pre-treatment mechanism 4 includes a first flange 7, a second flange 8 and a treatment pipe 9. A first flange 7 is provided on one side of the intake pipe 3. Sealing pipes 10 that fit the inner wall of the treatment pipe 9 are provided on the opposite sides of the first flange 7 and the second flange 8. A locking screw 11 that is inserted into the first flange 7 and the other end of the intake pipe 3 is provided on one side of the second flange 8. A locking nut 12 is threadedly connected to the outer surface of the locking screw 11. A baffle 13 is fixedly installed inside the treatment pipe 9. A filter barrel 14 that fits one side of the baffle 13 is inserted into the treatment pipe 9. A sealing pad 15 that fits the inner wall of the treatment pipe 9 is fixedly connected to one side of the filter barrel 14. One side of the filter barrel 14 and the sealing pad 15 are both inclined.

[0022] Among them, a filter barrel 14 for filtering impurities in the waste gas is provided inside the treatment pipe 9, and pre-filtration is carried out when the waste gas passes through, preventing impurities contained in the waste gas from entering the inside of the spray tower 1. The provided treatment pipe 9 can be hermetically installed by means of the first flange 7, the second flange 8 and the sealing pipe 10, and the installation of the locking screw 11 and the locking nut 12 can prevent the treatment pipe 9 from leaking waste gas during use. Moreover, one side of the filter barrel 14 and the sealing pad 15 are both inclined, so that when the waste gas enters, the impurities can be stacked on the inclined side by the continuous blowing of the waste gas, preventing the impurities from accumulating too much on the front and affecting the air intake efficiency.

[0023] Please refer to Figure 1 and Figure 2 , the water supply mechanism 6 includes a supply pump 25, a water inlet pipe 26, a support rod 27 and a guide ring 28.

[0024] Among them, the ammonia-containing wastewater after being sprayed by the spray water is discharged to the bottom of the spray tower. Subsequently, the supply pump 25 works, and it is discharged into the pharmaceutical treatment mechanism 5 through the water inlet pipe 26 and the water outlet pipe 29 for wastewater deammoniation treatment. The provided water outlet pipe 29 is lapped on the guide ring 28 with an arc-shaped top, and such a setting can prevent the water outlet pipe 29 from being bent when discharging water and affecting the water outlet efficiency.

[0025] Please refer to Figure 1 and Figure 2, the chemical treatment mechanism 5 includes a treatment tank 16, a drive motor 21, a positioning rod 22 and a stirring blade 23.

[0026] Among them, after the wastewater is discharged into the interior of the treatment tank 16, the chemical agent is placed inside the treatment tank 16, and then the drive motor 21 is started to operate. The drive motor 21 drives the stirring blade 23 to rotate along the positioning rod 22, so that the chemical agent can be fully contacted and treated with the wastewater. Subsequently, the treated wastewater can be discharged through the drain pipe 24.

[0027] Please refer to Figure 1 and Figure 2 , two groups of clamping grooves 17 are formed on the treatment tank 16, a clamping block 18 is inserted into the interior of the clamping groove 17, a filter screen 19 is fixedly installed on the clamping block 18, and a handle 20 is fixedly installed on the top of the filter screen 19.

[0028] Among them, the provided filter screen 19 can filter and treat the discharged wastewater. Such a setting can prevent impurities contained in the wastewater from flowing back again. Moreover, the filter screen 19 is installed through the clamping grooves 17 and the clamping blocks 18, which facilitates the removal and installation of the filter screen 19, and is convenient for maintaining the filter screen 19 and cleaning the impurities attached to the surface.

[0029] In use, first of all, by setting up the spray tower 1, during the waste gas treatment, the treated water can be combined with the waste gas to dissolve and capture ammonia nitrogen to form ammonia-containing wastewater. Subsequently, the ammonia-containing wastewater is transported to the chemical treatment mechanism 5 by the water supply mechanism 6 for rapid deammoniation treatment. Such a waste gas treatment method is convenient for treating waste gas with a high ammonia nitrogen content, has strong treatment continuity and higher treatment efficiency. Before the waste gas treatment, the pre-treatment mechanism 4 can preliminarily filter the impurities in the waste gas to prevent the waste gas from affecting the spraying efficiency of the spray tower during treatment.

The arranged treatment pipe 9 can be hermetically installed by means of the first flange 7, the second flange 8 and the sealing pipe 10, and the installation of the locking screw 11 and the locking nut 12 can prevent the waste gas from leaking during the use of the treatment pipe 9. Moreover, one side of the filter barrel 14 and the gasket 15 are both inclined, so that when the waste gas enters, the impurities can be stacked on the inclined side by the continuous blowing of the waste gas, preventing the impurities from accumulating too much on the front and affecting the air intake efficiency. The ammonia-containing wastewater after being sprayed by the spray water drains to the bottom of the spray tower, and then the supply pump 25 operates. The wastewater is discharged to the interior of the chemical treatment mechanism 5 through the water inlet pipe 26 and the water outlet pipe 29 for wastewater deammoniation treatment. The arranged water outlet pipe 29 is lapped on the guide ring 28 with an arc-shaped top, and such a setting can prevent the water outlet pipe 29 from being bent when discharging water and affecting the water outlet efficiency. After the wastewater drains into the treatment tank 16, the chemical agent is placed in the treatment tank 16, and then the driving motor 21 is started to operate. The driving motor 21 drives the stirring blade 23 to rotate along the positioning rod 22, so that the chemical agent can be fully contacted with the wastewater for treatment. Subsequently, the treated wastewater can be discharged through the drain pipe 24.
