Description

Technical Field

[0001] This utility model relates to the field of waste flue gas treatment technology, specifically to a spray-type catalytic reactor. Background Technology

[0002] To meet emission standards, waste flue gas is usually denitrified when it is emitted. The flue gas enters the reaction tower and is treated by spraying denitrification liquid and contacting the flue gas to carry out the denitrification reaction. The denitrification reaction effect is improved by the action of the catalyst layer. Since the waste flue gas contains a large number of dust particles, directly passing it into the reaction tower can easily affect the contact reaction between the denitrification liquid and the waste flue gas.

[0003] In summary, a spray-type catalytic reactor is currently needed. Utility Model Content

[0022] Example 1

[0023] To address the technical problems in the background section, the following spray-type catalytic reactor is provided:

[0024] Combination Figures 1-5 As shown, the present invention provides a spray-type catalytic reactor, including a reactor body 1, an exhaust pump 2 connected to the upper end of the reactor body 1, a denitrification liquid storage tank 3 located at the upper end of the reactor body 1, a scale window 4 on the front side of the denitrification liquid storage tank 3, a delivery pump 5 connected to the lower end of the denitrification liquid storage tank 3, the delivery pump 5 being connected to a connecting pipe 6, the end of the connecting pipe 6 away from the delivery pump 5 passing through the reactor body 1 and connecting to a spray pipe 7, the spray pipe 7 being located at the top of the reactor body 1, a nozzle 8 located at the lower end of the spray pipe 7, and a through-hole groove 9 opened at the center of the spray pipe 7.

[0025] The denitrification liquid in the denitrification liquid storage tank 3 is fed into the spray pipe 7 through the connecting pipe 6 by the infusion pump 5 and sprayed out through the nozzle 8 to contact the waste gas for denitrification treatment. The passage groove 9 and the gap between the spray pipe 7 and the top of the reactor body 1 are used for the passage of the treated waste gas, which is then extracted and discharged by the exhaust pump 2.

[0026] In this embodiment, the reactor body 1 includes a drawer box 101, which is disposed through the left side of the reactor body 1. A through hole 102 is provided in the bottom of the drawer box 101. The drawer box 101 is filled with a catalyst layer 103. A first bolt 104 is disposed through the left side of the drawer box 101. One end of the first bolt 104 is threaded to the reactor body 1. The reactor body 1 also includes a drain pipe 105, which is connected to the lower end of the reactor body 1. The lower end of the drain pipe 105 is connected to a collection box 106.

[0027] The catalyst layer 103 helps to improve the denitrification reaction treatment of denitrification liquid and waste flue gas. The first bolt 104 is periodically removed to pull out the box 101, which facilitates the replacement and maintenance of the catalyst layer 103.

[0028] Example 2

[0029] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0030] In this embodiment, the reactor body 1 also includes a filter box 107. The filter box 107 is connected to the right side of the reactor body 1. A swing rope 108 is fixedly installed at the top inner end of the filter box 107. The lower end of the swing rope 108 is connected to a swing ball 109. The reactor body 1 also includes a sealing pull plate 110. The sealing pull plate 110 is sealed to the upper end of the filter box 107.

A box cover 114 is provided on the front side of the filter box 107. A third bolt 115 is threaded through the box cover 114. One end of the third bolt 115 is threaded to the filter box 107.

[0031] The pendulum rope 108, driven by the exhaust gas, causes the pendulum ball 109 to swing. The pendulum ball 109 strikes the filter layer 112, which helps to improve the removal of dust particles filtered by the filter layer 112 and maintain its permeability and filtration effect.

[0032] Example 3

[0033] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0034] In this embodiment, the reactor body 1 also includes a filter layer 112. The lower end of the sealing pull plate 110 is provided with a filter layer 112 and an activated carbon adsorption layer 113. The activated carbon adsorption layer 113 is located on the left side of the filter layer 112, and the filter layer 112 is located on the left side of the pendulum ball 109.

[0035] The waste flue gas is filtered and adsorbed by the filter layer 112 and the activated carbon adsorption layer 113, reducing the amount of dust particles in the waste flue gas entering the reactor body 1.

[0036] Working principle and usage process of this utility model:

[0037] In use:

[0038] Step 1: The waste gas enters the filter box 107, where it is filtered and adsorbed by the filter screen layer 112 and the activated carbon adsorption layer 113, reducing the amount of dust particles in the waste gas entering the reactor body 1 and affecting the denitrification treatment of the waste gas.

[0039] Step 2: Under the blowing of the waste gas, the pendulum rope 108 drives the pendulum ball 109 to swing. The pendulum ball 109 hits the filter layer 112, which helps to improve the falling of dust particles filtered by the filter layer 112, maintain its permeability and filtration effect. The second bolt 111 can be removed periodically, and the filter layer 112 and activated carbon adsorption layer 113 can be pulled out for maintenance or replacement through the sealing pull plate 110. The third bolt 115 can be removed, the box cover 114 can be opened, and the inside of the filter box 107 can be cleaned.

[0040] Step 3: The filtered waste gas enters the reactor body 1. The denitrification liquid in the denitrification liquid storage tank 3 is fed into the spray pipe 7 through the connecting pipe 6 by the liquid pump 5. It is sprayed out through the nozzle 8 and comes into contact with the waste gas for denitrification treatment. The denitrification liquid falls on the catalyst layer 103. When the waste gas passes through the catalyst layer 103, the catalyst layer 103 helps to improve the denitrification reaction between the denitrification liquid and the waste gas. The first bolt 104 is removed and the box 101 is pulled out to facilitate the maintenance and replacement of the catalyst layer 103.
