[0030] See also Figures 1 to 6 , the utility model provides a technical solution:

[0031] A reaction device for producing a denitration catalyst comprises a reactor 1, a pneumatic mixing component 2 is arranged inside the reactor 1, and a mechanical mixing component 3 is arranged inside the reactor 1;

[0032] The pneumatic mixing assembly 2 includes a feed inlet 201, an air pump 202, an air pipe 203, a glass fiber filter layer 204 and a polyester fiber filter layer 205. The two feed inlets 201 are arranged at the top of the reactor 1, the air pump 202 is arranged on both sides of the reactor 1, the air pipe 203 is arranged on one side of the air pump 202, the glass fiber filter layer 204 is arranged at the inner top of the air pipe 203, the polyester fiber filter layer 205 is arranged below the glass fiber filter layer 204, and one end of the air pipe 203 extends to the interior of the reactor 1.

[0033] Specifically, Figure 1 As shown, the mechanical mixing assembly 3 includes a fixed seat 301, a stirring motor 302, a rotating rod 303 and a stirring blade 304. The fixed seat 301 is arranged on the top of the reactor 1, the stirring motor 302 is arranged on the top of the fixed seat 301, the rotating rod 303 is bolted to the bottom of the stirring motor 302, and the stirring blade 304 is arranged at one end of the rotating rod 303 away from the stirring motor 302.

[0034] Specifically, Figure 1 As shown, a side leakage port 4 is provided at one end of the gas delivery pipe 203 , and the side leakage port 4 is located inside the reactor 1 .

[0035] Specifically, Figure 1 As shown, a discharge pipe 5 is provided at the bottom of the reactor 1 , a solenoid valve 6 is provided inside the discharge pipe 5 , and a guide pipe 7 is provided on one side of the discharge pipe 5 .

[0036] Specifically, Figure 3 As shown, a heat preservation chamber 8 is provided inside the reactor 1, and the heat preservation material inside the heat preservation chamber 8 is aluminum silicate fiber.

[0037] Specifically, Figure 1 As shown, an inlet pipe 9 is provided on one side of the top of the reactor 1 , and an outlet pipe 10 is provided on the bottom of the other side of the reactor 1 . The outlet pipe 10 and the inlet pipe 9 are connected to the interior of the heat preservation chamber 8 .

[0038] First, the raw material of the liquid desulfurization catalyst is put in through the two feed ports 201 set at the top of the reactor 1. The design of the two feed ports 201 ensures that the raw material can enter the reactor 1 accurately and quickly. Next, the air pump 202 starts to work to generate a stable airflow, which is transported to the reactor 1 through the air pipe 203. In the air pipe 203, the airflow first passes through the glass fiber filter layer 204 located at the top to filter out larger particles and impurities. Then, the airflow continues to descend and passes through the polyester fiber filter layer 205 located below the glass fiber filter layer 204 to further remove fine particles and impurities to ensure that the airflow entering the reactor 1 is pure. One end of the air pipe 203 extends to the inside of the reactor 1 and is provided with a side leakage port 4. In this way, the airflow can be evenly ejected from the side leakage port 4 and fully mixed with the liquid desulfurization catalyst raw material in the reactor 1. The introduction of the airflow not only helps It can not only promote the uniform dispersion of raw materials, but also increase the contact area between raw materials and promote the progress of chemical reactions. At the same time, the stirring motor 302 drives the rotating rod 303 and the stirring blade 304 to rotate in the reactor 1, and further promotes the mixing of raw materials by physical stirring. The dual effects of mechanical stirring and air flow disturbance make the mixing effect of the liquid desulfurization catalyst more uniform and efficient. In addition, a discharge pipe 5 is arranged at the bottom of the reactor 1. The switch is controlled by the solenoid valve 6, so that the mixed liquid desulfurization catalyst can be conveniently discharged. At the same time, the insulation chamber 8 arranged inside the reactor 1 adopts aluminum silicate fiber as the insulation material, which can effectively keep the temperature inside the reactor 1 stable and is conducive to the progress of chemical reactions. Finally, an inlet pipe 9 is arranged on one side of the top of the reactor 1, and gas can be added into the insulation chamber 8 to flush the surface of the glass fiber with gas, while the outlet pipe 10 on the other side is used to discharge the exhaust gas in the insulation chamber 8.

[0039] Specifically, Figure 1 As shown, a support base 11 is disposed at the bottom of the reaction kettle 1 , and a support leg 12 is disposed at the bottom of the support base 11 .

[0040] Specifically, Figure 1 As shown, a support ring 13 is provided at the bottom of the support leg 12 , and the support ring 13 is located below the reaction kettle 1 .

[0041] The support base 11 and the support legs 12 support the bottom of the reactor 1 , and the support ring 13 expands the ground contact area of ​​the support legs 12 .

[0042] By adopting the above technical solution, the problem that the existing denitration catalyst reaction device can only process powder but cannot mix the hydraulic denitration catalyst is solved.

[0043] Working principle: When the present application is in use, first, the raw material of the liquid desulfurization catalyst is put in through the two feed ports 201 arranged at the top of the reactor 1. The design of the two feed ports 201 ensures that the raw material can accurately and quickly enter the reactor 1. Next, the air pump 202 starts to work to generate airflow, and the airflow is transported to the inside of the reactor 1 through the air pipe 203. In the air pipe 203, the airflow first passes through the glass fiber filter layer 204 located at the top of the inner part to filter out large particles and impurities. Then, the airflow continues to descend and passes through the polyester fiber filter layer 205 located below the glass fiber filter layer 204 to further remove small particles and impurities to ensure that the airflow entering the reactor 1 is pure. One end of the air pipe 203 extends to the inside of the reactor 1 and is provided with a side leakage port 4. In this way, the airflow can be evenly ejected from the side leakage port 4 and fully mixed with the liquid desulfurization catalyst raw material in the reactor 1. The introduction of the airflow It not only helps to evenly disperse the raw materials, but also increases the contact area between the raw materials and promotes the chemical reaction. At the same time, the stirring motor 302 drives the rotating rod 303 and the stirring blade 304 to rotate in the reactor 1, and further promotes the mixing of the raw materials by physical stirring. The dual effects of mechanical stirring and air flow disturbance make the mixing effect of the liquid desulfurization catalyst more uniform and efficient. A discharge pipe 5 is arranged at the bottom of the reactor 1. The switch is controlled by the solenoid valve 6, so that the mixed liquid desulfurization catalyst can be conveniently discharged. At the same time, the insulation chamber 8 arranged inside the reactor 1 adopts aluminum silicate fiber as the insulation material, which can effectively keep the temperature inside the reactor 1 stable, which is conducive to the chemical reaction. Finally, an inlet pipe 9 is arranged on one side of the top of the reactor 1, and gas can be added into the insulation chamber 8 to flush the surface of the glass fiber, while the outlet pipe 10 on the other side is used to discharge the exhaust gas in the insulation chamber 8.
