Description

Technical Field

[0001] This utility model relates to the field of dry desulfurization agent technology, specifically to a high-efficiency utilization device for dry desulfurization agents. Background Technology

[0002] Dry desulfurization mainly includes adsorption, metal oxide absorption, catalytic reaction, high-energy activation oxidation, and charged dry injection desulfurization. Among them, adsorption utilizes the high selectivity of adsorbents such as activated carbon, silica gel, activated alumina, and molecular sieves for SO2 gas to adsorb SO2 in flue gas, thereby purifying the flue gas. The adsorbent can be reused after appropriate regeneration.

[0003] Existing adsorption-based utilization devices have the following problems: Existing adsorption methods are not suitable for primary filtration of flue gas. The flue gas is directly purified by passing through the filter, which leads to excessive dust accumulation on the filter and the need for regular maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a device for the efficient utilization of dry desulfurizing agents to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency utilization device for dry desulfurization agent, comprising a tank, an outlet pipe provided on the tank, an inlet pipe provided on the surface of the tank, a filter provided in the tank, a primary filtration structure provided on the inlet pipe, the primary filtration structure comprising an installation frame, an insertion frame provided in the inlet pipe, a dust filter block provided in the insertion frame, a positioning structure provided in the inlet pipe, and a limiting structure provided on the inlet pipe.

[0006] Preferably, the positioning structure includes an elastic element, the elastic element is installed in the inlet pipe, the elastic element is provided with a locking head, and the insertion frame is provided with a locking groove.

[0007] Preferably, the limiting structure includes a fixed frame, the surface of the inlet pipe is provided with a fixed frame, a rotating column is connected to the fixed frame, a stop block is provided on the surface of the inlet pipe, a pressure block is provided on the surface of the rotating column, and a pressure groove is provided on the insertion frame.

[0008] Preferably, a screw is connected to the rotating column, a threaded block is connected to the screw, a fixing plate is provided on the surface of the threaded block, and a limit head is provided on the surface of the fixing plate.

[0009] Preferably, a spring is provided on the surface of the screw, and one end of the spring is fixed to the surface of the threaded block.

[0010] Preferably, the spring is in a compressed state.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Insert the insert frame into the mounting frame so that the dust filter block is located inside the inlet pipe. When the flue gas passes through the inlet pipe, the dust filter block can perform primary filtration of particulate matter and impurities in the flue gas, greatly reducing the amount of dust particles entering the tank, which can extend the service life of the filter and reduce the maintenance frequency. When the insert frame is inserted into the mounting frame, it will push the elastic element and make the clamp head lock in the slot, thus achieving fixation. Rotate the rotating column clockwise to make the pressure block rotate into the pressure groove. When the rotating column abuts against the surface of the stop block, it will press down on the insert frame, so that the insert frame is firmly fixed in the mounting frame, thereby achieving the limiting and fixing of the insert frame.

Detailed Implementation

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1 and Figure 2This utility model provides a high-efficiency utilization device for dry desulfurization agent, including a tank 1, an outlet pipe 2 on the tank 1, an inlet pipe 3 on the surface of the tank 1, a filter 4 in the tank 1, and a primary filtration structure 5 on the inlet pipe 3.

[0021] Specifically, the flue gas enters the tank 1 through the inlet pipe 3. The induced draft fan draws air from inside the tank 1 through the outlet pipe 2, causing the flue gas to move upward. Then it passes through the filter 4. The filter 4 uses the high selective adsorption properties of adsorbents such as activated carbon, silica gel, activated alumina, and molecular sieves for SO2 gas to adsorb SO2 in the flue gas, thereby achieving the purpose of purifying the flue gas by adsorption.

[0022] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a high-efficiency utilization device for dry desulfurization agent. The primary filter structure 5 includes an installation frame 51, an installation frame 51 installed in the inlet pipe 3, an insert frame 52 inserted in the installation frame 51, a filter block 53 filled in the insert frame 52, a positioning structure 54 provided in the inlet pipe 3, and a limiting structure 55 provided on the inlet pipe 3.

[0023] The positioning structure 54 includes an elastic element 541, which is installed in the inlet pipe 3. The elastic element 541 is provided with a card head 542, and the insertion frame 52 is provided with a card slot 543.

[0024] The limiting structure 55 includes a fixed frame 551, a fixed frame 551 welded to the surface of the inlet pipe 3, a rotating column 552 rotatably connected in the fixed frame 551, a stop block 553 integrally formed on the surface of the inlet pipe 3, a pressure block 554 provided on the surface of the rotating column 552, and a pressure groove 555 provided on the insertion frame 52.

[0025] The rotating column 552 is rotatably connected to a screw 556, and a threaded block 557 is threadedly connected to the screw 556. A fixing plate 558 is integrally formed on the surface of the threaded block 557, and a limit head 559 is integrally formed on the surface of the fixing plate 558. A spring 5510 is provided on the surface of the screw 556, and one end of the spring 5510 is fixed to the surface of the threaded block 557. The spring 5510 is in a compressed state, which makes the connection between the threaded block 557 and the screw 556 more stable.

[0026] Specifically, insert frame 52 is inserted into mounting frame 51, so that dust filter block 53 is located inside inlet pipe 3. When flue gas passes through inlet pipe 3, dust filter block 53 can perform primary filtration of particulate matter and impurities in flue gas, greatly reducing the amount of dust particles entering the tank 1, which can extend the service life of filter 4 and reduce maintenance frequency. When insert frame 52 is inserted into mounting frame 51, it will push elastic element 541, causing clamp head 542 to be locked in clamp slot 543, thus achieving fixation. Rotating rotating column 552 clockwise causes pressure block 554 to rotate into pressure groove 555. When the rotating column 552 abuts against the surface of the stop block 553, it will press down on the insert frame 52, so that the insert frame 52 is firmly fixed in the mounting frame 51, thereby achieving the limiting and fixing of the insert frame 52. When the screw 556 is rotated, since the threaded block 557 is threadedly connected to the screw 556, the threaded block 557 will move when the screw 556 rotates, thereby driving the fixing plate 558, so that the limiting head 559 is inserted into the stop block 553, thereby achieving reinforcement and fixing, and improving the stability of the installation of the insert frame 52. The insertion frame 52 is installed through the limiting structure 55, which is also relatively convenient for disassembly.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
