An scr plate catalyst soot bench

Abstract

This utility model relates to the field of catalyst cleaning technology, specifically an SCR plate catalyst cleaning stand. The purpose of this utility model is to provide an SCR plate catalyst cleaning stand that, through the coordinated action of an air jetting mechanism and a pushing mechanism, enables mobile and efficient dust removal. The air jetting mechanism uses directional high-pressure airflow to impact the catalyst surface over a large area, rapidly removing attached dust. The pushing mechanism drives the entire equipment to move smoothly, ensuring coverage of the entire area to be cleaned. Simultaneously, the airflow guiding design gathers the removed dust into clumps, preventing secondary dispersion. Combined with the negative pressure adsorption function of the dust suction mechanism, the gathered dust is sucked into the dust collection device in real time, forming a closed-loop process of "blowing-gathering-adsorption." This design not only improves dust removal efficiency, being faster than traditional manual cleaning, but also effectively controls dust diffusion, ensuring a clean working environment and achieving dual optimization of catalyst maintenance and environmental protection requirements.

Description

Technical Field

[0001] This utility model relates to the field of catalyst cleaning technology, specifically to an SCR plate-type catalyst cleaning frame. Background Technology

[0002] The core role of catalysts in the production process is to accelerate the conversion of nitrogen oxides and reducing agents through catalytic reactions, efficiently converting them into harmless nitrogen and water vapor, thereby reducing pollutant emissions in exhaust gas or flue gas. At the same time, the addition of metal mesh structures and anti-poisoning additives improves the catalyst's wear resistance, sulfur poisoning resistance, and service life. It is widely used in coal-fired power plants, industrial boilers, and diesel vehicle exhaust treatment. However, byproducts are also generated during the catalytic process, which adhere to the catalyst surface and reduce the catalyst's activity. Cleaning these byproducts can increase the catalytic rate and catalytic effect.

[0003] At present, the cleaning of SCR plate catalysts mainly relies on manual operation. This traditional cleaning method is not only inefficient and consumes a lot of manpower and time, but also has a harsh working environment. Operators need to be exposed to dusty, high-temperature and even toxic and harmful gas environments for a long time, which poses a high health risk. Meanwhile, manual cleaning makes it difficult to collect and treat dust simultaneously, and the cleaning process can easily cause secondary pollution, such as dust spreading to the surrounding environment or equipment gaps, affecting subsequent operating efficiency. The uniformity and thoroughness of manual cleaning are difficult to guarantee, which may result in residual pollutants on the catalyst surface, reducing its catalytic activity and service life.

Detailed Implementation

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-4 As shown, an SCR plate catalyst cleaning stand includes a support 1 for holding the catalyst housing and fixing other equipment. A dust-collecting mechanism 2 is provided on the surface of the support 1, which uses strong suction to draw dust blown off the catalyst surface into the inner cavity. A first housing 3 is provided on the surface of the dust-collecting mechanism 2 to protect some parts inside the dust-collecting mechanism 2. A first fixing block 4 is provided on the surface of the dust-collecting mechanism 2, and a gas guide pipe 5 is fixed on the surface of the first fixing block 4. A jetting mechanism 6 is provided on the surface of the gas guide pipe 5 for connecting the dust-collecting mechanism 2 and the jetting mechanism 6. A connecting rod 7 is fixed on the surface of the first fixing block 4, and a second fixing block 8 is fixed on the surface of the connecting rod 7. The first fixing block 4, connecting rod 7, and second fixing block 8 are used to fix the gas guide pipe 5. A pushing mechanism 9 is provided on the surface of the gas guide pipe 5 to push the jetting mechanism 6 for directional movement. A third fixing block 10 is provided on the surface of the dust-collecting mechanism 2 to fix some components on the dust-collecting mechanism 2. Second housings 11 are fixed on both sides of the support 1 surface to protect some parts of the pushing mechanism 9. The dust on the catalyst surface is cleaned using jetting and suction.

[0016] The dust collection mechanism 2 includes a gas-gathering shell 21 fixed to the surface of the support 1. An air inlet 22 is provided on the surface of the gas-gathering shell 21, and an air inlet pipe 23 is connected to the surface of the gas-gathering shell 21. An ash storage bin 24 is connected to the surface of the air inlet pipe 23. A drawer 25 slides along the inner wall of the ash storage bin 24, and a handle 26 is fixed to one side of the drawer 25. An air pump 28 is fixed to the surface of the ash storage bin 24, and a filter port 27 is fixed to the surface of the air pump 28. When the air pump 28 is activated, the suction force generated by the air pump 28 is transmitted through the air inlet pipe 23 to the catalyst to be cleaned. The dust is placed inside the box, and then the air-collecting shell 21 carries the absorbed dust into the air inlet 22. The air-collecting shell 21 can suck up all the dust on the same plane, increasing the absorption area. Then, the dust is transported to the dust storage bin 24 by the air inlet pipe 23 connected to the air inlet 22 and falls into the drawer 25. The filter port 27 fixed to the air pump 28 input port can be used to filter the dust down to prevent it from entering the air pump 28 and damaging it. After collection is completed, the dust in the drawer 25 is emptied by pulling the handle 26 to complete the cleaning purpose.

[0017] The jetting mechanism 6 includes a first retractable hose 61 connected to the surface of the air guide pipe 5. The first retractable hose 61 can be extended by unfolding and folding under external force. The surface of the first retractable hose 61 is connected to a gas distribution pipe 62, and the surface of the gas distribution pipe 62 is connected to a number of jet nozzles 63. The jet nozzles 63 are venturi tubes. When the air pump 28 sprays out the gas, it is transmitted to the first retractable hose 61 through the air guide pipe 5 to provide jetting kinetic energy for the jetting mechanism 6. The gas is then transmitted through the first retractable hose 61 to the gas distribution pipe 62, and the gas is distributed to each jet nozzle 63. Since the jet nozzles 63 are venturi tubes, the delivered airflow can be compressed and accelerated, giving it a stronger impact force, which causes the dirt attached to the catalyst surface to fall off.

[0018] The driving mechanism 9 includes a branch pipe 91 connected to the surface of the air duct 5. The surface of the branch pipe 91 is connected to an air supply pipe 92. Both sides of the surface of the air supply pipe 92 are connected to second retractable hoses 93. Both sides of the surface of the air supply pipe 92 are fixed with springs 94. The other end of the springs 94 is fixed with an auxiliary support block 95. When the air pump 28 delivers airflow to the air duct 5, a portion of the airflow will enter the air supply pipe 92 connected to it through the branch pipe 91. Then, the air supply pipe 92 delivers the airflow to the second retractable hoses 93 on both sides. Once the gas in the second retractable hose 93 increases, it will unfold and fold, extending and lengthening, thereby driving the jet mechanism 6 to move horizontally. When the cleaning is finished, the internal airflow will dissipate on its own. At the same time, the springs 94, which have been in a taut state, will pull the auxiliary support block 95 back to the initial position. Since only a small portion of the airflow enters the branch pipe 91, the movement speed is not fast under the premise that it can move again, thus making the cleaning more efficient.

[0019] Both the first retractable hose 61 and the second retractable hose 93 are foldable and retractable hoses. Under the action of external force, the hose length can be extended by unfolding the folded layer.

[0020] The jet nozzle 63 is designed to be tilted downwards at the same angle, which can remove dust from the catalyst surface and gather the dust when the jet mechanism 6 is pushed forward.

[0021] Working Principle: When cleaning dust from the catalyst surface is required, the operator starts the air pump 28. Driven by the air pump 28, gas is ejected and transmitted through the air guide pipe 5. Most of the airflow passes through the first retractable hose 61 into the distribution pipe 62. Under the distribution of the air guide pipe 62, the airflow is ejected from the jet nozzle 63. Due to the design of the jet nozzle 63, the airflow is ejected more rapidly, thus enhancing the cleaning of dust and better removing and collecting dust from the catalyst surface. Simultaneously, a small portion of the airflow enters the branch pipe 91 and is transported to the gas delivery pipe 92, which then delivers it to both ends. When the gas enters the second retractable hose 93 from the gas delivery pipe 92, the second retractable hose 93 begins to expand and extend, simultaneously causing the auxiliary support block 95 fixed at one end of the second retractable hose 93 to move forward. Because both sides are identical, both sides push forward simultaneously, bringing... The jetting mechanism 6 moves horizontally to deeply clean the catalyst. Simultaneously, the air pump 28 outputs gas and generates suction. When the suction acts on the inner cavity of the ash storage bin 24, the corresponding air inlet pipe 23 absorbs the dust gathered by the jetting mechanism 6. During the dust absorption process, the gas collecting shell 21 increases the absorption area. After the dust is brought into the interior of the ash storage bin 24, it falls into the drawer 25. The filter port 27 can block the dust during the suction process. The dust suction mechanism 2 can absorb almost all the dust and perform a relatively sealed treatment. After the absorption is completed, the drawer 25 is pulled out to collect the dust. Without the gas expansion effect, the second retractable hose 93 will retract under the pull of the internal fixed spring 94, returning the jetting mechanism 6 to its original position, thus completing the cleaning of dust on the catalyst surface, reducing the workload of the staff and increasing the cleaning efficiency.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
