However, after using for a period of time, the concentration of the denitrating agents will be affected. Therefore, it is necessary to stop the machine to replace the new denitrating agents, which will affect the flue gas treatment speed and efficiency.

[0004] The utility model provides a continuous denitration device to solve the problem that when denitrating currently, after using the denitrating agents for a period of time, the concentration of the denitrating agents will be affected, so it is necessary to stop the machine to replace the new denitrating agents, which will affect the flue gas treatment speed and efficiency.

The inner cavity of the main body 1 is provided with a spraying mechanism 3. The spraying mechanism 3 can enable the equipment to ensure the concentration of the denitrification agent in the equipment, without affecting the denitrification effect due to too low concentration, and without shutting down due to replacement of the denitrification agent, affecting the gas treatment speed and efficiency.

[0025] like Figure 2 As shown, the adjustment mechanism 2 includes a fixed tube 21, one side of the lower end of the fixed tube 21 is fixedly connected to one side of the main body 1, and fixed plates 22 are provided at both ends of the fixed tube 21. The upper end of the fixed plate 22 is provided with an electric telescopic rod 23. The upper end of the fixed tube 21 is sleeved and connected to an extension tube 24, and the lower end of the other side of the extension tube 24 is fixedly connected to an air intake cover 25;

[0026] Both ends of the fixing tube 21 are welded to one end of the fixing plate 22 , and the upper end of the fixing plate 22 is fixedly connected to the lower end of the electric telescopic rod 23 .

[0027] As can be seen from the above, there are two groups of fixed plates 22 and electric telescopic rods 23, which are symmetrically distributed at both ends of the fixed tube 21. This can stably enable the extension tube 24 to slide up and down along the inner wall of the fixed tube 21, making it easy to adjust the air intake hood 25 according to actual usage.

[0028] like Figure 3 As shown, the spray mechanism 3 includes a water pump 31, one end of which is detachably connected to the rear end of the main body 1, and circulating water pipes 32 are provided at both ends of the water pump 31. A spray pipe 33 is provided on one side of the circulating water pipe 32, and the lower end of the spray pipe 33 is fixedly connected to the upper end of the spray head 34. One side of the circulating water pipe 32 is fixedly connected to one side of a liquid extraction pipe 35, the outer surface of the liquid extraction pipe 35 is fixedly connected to the inner wall of the flow valve 36, and one side of the liquid extraction pipe 35 is connected to one side of a liquid storage tank 37 through which the upper end of the liquid storage tank 37 is fixedly connected to the lower end of the liquid injection port 38;

[0029] Both ends of the water pump 31 are connected to the outer surface of the circulating water pipe 32, and one side of the circulating water pipe 32 is fixedly connected to the middle of the spray pipe 33;

[0030] The number of the shower heads 34 on the outside is twelve, and the number on the inside is six.

[0031] As can be seen from the above, the spray pipe 33 and the spray head 34 are two groups, and the spray head 34 can be an atomizing nozzle to more comprehensively cover the gas and perform denitrification treatment.

[0032] like Figure 4 As shown, the opening and closing mechanism 8 includes a sleeve 81, one end of which is welded to one end of the maintenance door 7, a rod 82 is provided in the middle of the inner cavity of the maintenance door 7, and a return spring 83 is provided on the outer surface of the rod 82, one side of the return spring 83 is fixedly connected to one side of the annular baffle 84, the upper end of the rod 82 is welded to the lower end of the toggle rod 85, and one side of the rod 82 is plugged into the middle of the insert block 86;

[0033] The middle portion of the inner cavity of the sleeve 81 is embedded with the outer surface of the insertion rod 82 , and the outer surface of the insertion rod 82 is sleeved with the inner wall of the return spring 83 .

[0034] As can be seen from the above, the insertion hole in the middle of the insertion block 86 is larger than the outer diameter of the insertion rod 82 , and the outer diameter of the annular baffle 84 is larger than the outer diameter of the insertion rod 82 .

[0035] The working principle of the present utility model is as follows: Firstly, by controlling the telescopic movement of the electric telescopic rod 23, the extension pipe 24 can be driven to adjust up and down simultaneously, facilitating the adjustment of the suction height of the air intake hood 25. The waste gas enters the device through the air intake hood 25, the extension pipe 24, and the fixed pipe 21 for denitration treatment. Then, by starting the water pump 31, the water pump 31 extracts the denitration agent at the bottom of the device and atomizes and sprays it from the spray head 34, making full contact and reaction with the uniformly entering gas to denitrate the gas. The denitrated gas is discharged from the exhaust pipe 6. After a period of time, the flow valve 36 is opened and adjusted to an appropriate size, and then the water pump 31 is started. The water pump 31 extracts a small amount of the denitration agent in the liquid storage tank 37 into the device to ensure the concentration of the denitration agent, and the drain pipe is regularly opened to discharge a certain amount of the denitration agent to prevent the liquid level of the denitration agent in the device from being too high. Furthermore, by manually pulling the toggle rod 85 by the operator, the toggle rod 85 drives the plug rod 82 to move left and right. When the plug rod 82 moves, it compresses the return spring 83, and then drives the maintenance door 7 to close. Then, the toggle rod 85 is released, and under the elastic action of the return spring 83, the annular baffle 84 and the plug rod 82 are driven to move, so that the plug rod 82 is inserted into the plug block 86, facilitating the opening and closing of the maintenance door 7.
