Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a desulfurization tower with a rapid drainage structure. Background Art

[0002] With the rapid development of industry, the emission of sulfur oxides in coal-fired flue gas has continued to increase, seriously polluting the atmospheric environment. In order to reduce the emission of sulfur oxides, flue gas desulfurization technology has been widely used. The desulfurization tower is the core equipment of flue gas desulfurization technology, and its performance directly affects the desulfurization efficiency. However, the desulfurization tower still has many defects in actual use. For example, when treating flue gas, the traditional desulfurization tower needs to spray a large amount of liquid to desulfurize the flue gas, which will cause water accumulation in the tower. If the accumulated water in the tower is not discharged quickly, it will easily affect the desulfurization effect and the quality of flue gas emissions. Therefore, it is necessary to design a desulfurization tower with a rapid drainage structure. Utility Model Content

[0003] The purpose of the utility model is to provide a desulfurization tower with a rapid drainage structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a desulfurization tower with a rapid drainage structure, comprising a tower body, a water collecting tank and a fixed plate, a water collecting tank is fixedly installed on the outside of the tower body, a water pump is fixedly installed on the top of the water collecting tank on one side of the tower body, a drainage pipe extending into the water collecting tank is fixedly installed on the outside of the bottom of the tower body, a rotating rod is rotatably installed at the bottom end of the tower body, a push plate is fixedly installed on one side of the rotating rod, a fixed plate is fixedly installed in the tower body at the top of the push plate, a guide seat is fixedly installed on the top of the fixed plate, and a spray pipe is fixedly installed in the tower body at the top of the guide seat.

[0005] The flue gas is transported into the tower body, and the spray liquid in the water collecting tank is extracted by a water pump and transported to the spray pipe, which is convenient for flue gas desulfurization operation. The water flow into the bottom of the tower body is slowed down by the guide seat, which can reduce the accumulation of water at the bottom of the tower body. By distributing multiple drainage pipes around the bottom of the tower body, the accumulated water inside the tower body can be discharged more quickly. The push plate is driven to rotate by the rotating rod, which can increase the circulation effect of the water flow and improve the drainage efficiency.

[0006] Preferably, a water inlet is fixedly installed on the top of the water collecting tank, and a water outlet is fixedly connected to one side of the water collecting tank. The spray liquid required for desulfurization can be conveniently introduced into the water collecting tank through the water inlet, and the spray liquid can be conveniently replaced through the water outlet.

[0007] Preferably, a suction pipe extending into the water collecting tank is fixedly installed at the water suction end of the water pump, and a delivery pipe is fixedly connected between the water discharge end of the water pump and the spray pipe. The water pump is used to extract the spray liquid in the water collecting tank through the suction pipe and deliver it to the spray pipe through the delivery pipe.

[0008] Preferably, the tower body and the water collecting tank are fixedly installed by a support frame, and a spray head is fixedly installed at the bottom of the spray pipe. The support frame can conveniently support the tower body, and the spray liquid is sprayed out by the spray head, which can conveniently react with the flue gas.

[0009] Preferably, a protective shell is fixedly installed at the bottom of the tower body, and a motor corresponding to the rotating rod is fixedly installed inside the protective shell. The protective shell can conveniently protect the motor, and the motor can conveniently drive the rotating rod to rotate.

[0010] Preferably, a spiral guide groove is provided on the surface of the guide seat, and a water guide port is provided on the surface of the fixed plate outside the guide seat. The spray liquid flows along the spiral guide groove in a spiral manner, which can slow down the flow of water into the bottom of the tower body and reduce the accumulation of water at the bottom of the tower body. The spray liquid is guided to the fixed plate through the spiral guide groove and can flow downward to the bottom of the tower body through the water guide port.

[0011] Preferably, an air outlet pipe is fixedly installed on the top of the tower body, and an air inlet pipe is fixedly connected to one side of the tower body. The air inlet pipe can conveniently introduce the flue gas to be shed into the tower body, and the air outlet pipe can conveniently guide the flue gas after spray desulfurization.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Through the cooperation between the water collecting box, the drainage pipe and the push plate, multiple drainage pipes can be distributed around the bottom of the tower body, so that the accumulated water inside the tower body can be discharged more quickly. At the same time, the push plate has an inclined angle, and the push plate can be rotated to quickly push the accumulated water at the bottom to the drainage pipe, which can effectively increase the circulation effect of the water flow, and can quickly discharge the accumulated water inside the tower body to the water collecting box for collection, thereby improving the drainage efficiency.

[0014] 2. By setting up the fixed plate, the guide seat and the spiral guide groove, the guide seat is in a cone shape, which can make the sprayed water be introduced into the spiral guide groove. The water flows in a spiral along the spiral guide groove, which can effectively slow down the flow of water into the bottom of the tower body and reduce the accumulation of water at the bottom of the tower body.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment 1

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the desulfurization tower with a rapid drainage structure proposed by the utility model includes a tower body 1, a water collecting box 3 and a fixed plate 5. The water collecting box 3 is fixedly installed on the outside of the tower body 1, and a water pump 2 is fixedly installed on the top of the water collecting box 3 on one side of the tower body 1. A drainage pipe 103 extending into the water collecting box 3 is fixedly installed on the outside of the bottom of the tower body 1. A rotating rod 602 is rotatably installed at the bottom end of the tower body 1, and a push plate 7 is fixedly installed on one side of the rotating rod 602. A fixed plate 5 is fixedly installed in the tower body 1 on the top of the push plate 7, and a guide seat 502 is fixedly installed on the top of the fixed plate 5. A spray pipe 4 is fixedly installed in the tower body 1 on the top of the guide seat 502;

[0024] The working principle of the desulfurization tower with a rapid drainage structure based on Example 1 is as follows: by conveying the flue gas into the tower body 1, using the water pump 2 to extract the spray liquid in the water collecting box 3 through the water suction pipe 202, conveying it to the spray pipe 4 through the conveying pipe 201, and using the spray head 401 to spray the spray liquid, which can react with the flue gas conveniently and desulfurize the flue gas conveniently.

[0025] By distributing multiple drainage pipes 103 around the bottom of the tower body 1, the accumulated water inside the tower body 1 can be discharged more quickly. At the same time, the push plate 7 has a certain inclination angle and can be driven to rotate by the rotating rod 602, so that the accumulated water at the bottom can be quickly transferred to the drainage pipe 103, which can effectively increase the circulation effect of the water flow, and the accumulated water inside the tower body 1 can be quickly discharged to the water collecting tank 3 for collection, thereby improving the drainage efficiency.
