Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a combined glass fiber reinforced plastic columnar desulfurization tower. Background Art

[0002] The desulfurization tower is a tower-type equipment used for desulfurization treatment. The desulfurization tower mainly removes sulfides in the exhaust gas through a series of complex chemical reactions and physical processes, thereby achieving the purpose of purifying the air. The desulfurization tower is mainly used in coal-fired power plants and chemical metallurgical fields. In short, the desulfurization tower is an environmentally friendly and practical equipment, which plays a great role in environmental protection.

[0003] Some existing desulfurization towers have certain defects during use. The main reason is that the internal structural design of the desulfurization tower is not very reasonable, which leads to relatively low efficiency of desulfurization and dust removal, and the emission of flue gas cannot meet actual needs. Therefore, technical personnel in this field provide a combined fiberglass columnar desulfurization tower to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and the proposed combined glass fiber reinforced plastic column desulfurization tower, through the cooperation of the second water pump and the second delivery pipeline, the desulfurizer is transported to the ejector, so as to react with the sulfide in the exhaust gas, thereby achieving the desulfurization effect, and then the flue gas is discharged under the cooperation of the demister and the gas-liquid separation cooler.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined glass fiber reinforced plastic columnar desulfurization tower, including a desulfurization module, a collection module is slidably arranged on the lower end surface of the desulfurization module, a liquid tank module is fixedly connected to the surface of one side of the desulfurization module, and a recovery module is fixedly connected to the surface of the other side of the desulfurization module. The desulfurization module includes a desulfurization tower body, a gas-liquid separation cooler is fixedly connected to the surface of the upper end of the inner wall of the desulfurization tower body away from the center, a filter screen is fixedly connected to the surface of the lower end of the inner wall of the desulfurization tower body close to the center, and an annular pipe is fixedly connected to the surrounding surfaces of the inner wall of the desulfurization tower body;

[0006] The liquid tank module includes a liquid tank body, a partition plate is fixedly connected to the center of the liquid tank body, a first water pump is fixedly connected to the rear surface of the bottom end of the liquid tank body, a first delivery pipeline is fixedly connected to the output end of the first water pump, an ejector is fixedly connected to one side surface of the first delivery pipeline, a second water pump is fixedly connected to the front surface of the bottom end of the liquid tank body, and a second delivery pipeline is fixedly connected to the output end of the second water pump.

[0007] Through the above technical scheme, by arranging a gas-liquid separation cooler, a filter screen plate, a second water pump and a second delivery pipe at the output end inside the desulfurization tower body, the desulfurizer inside the liquid tank module can be transported to the inside of the desulfurization tower body through the second delivery pipe under the action of the second water pump, so as to desulfurize the harmful substances in the exhaust gas, so that it is fixed in the process of combining with the harmful components in the exhaust gas, and finally falls onto the filter screen plate. At the same time, other liquids after spraying will directly fall into the collection box, so as to facilitate its subsequent use. Because the material of the desulfurization tower body itself is glass fiber reinforced plastic, it is necessary to increase the stability of the surface of the desulfurization tower body before the desulfurization tower works, so that the hot water inside the liquid tank body is transported to the annular pipe under the cooperation of the first water pump and the first delivery pipe inside the liquid tank body, so as to heat the surface of the desulfurization tower body, so as to avoid the glass fiber reinforced plastic strength of the desulfurization tower body decreasing due to temperature reasons when the desulfurization tower body is working, thereby reducing the overall durability and carrying capacity of the desulfurization tower body.

[0008] Furthermore, an air inlet pipe is fixedly connected to the upper surface of one side of the desulfurization tower body near the center, and an air outlet pipe is fixedly connected to the upper surface of the desulfurization tower body;

[0009] Through the above technical solution, the exhaust gas is transported into the desulfurization tower body by the combination of the air inlet pipe and other external equipment, and the purified flue gas can be discharged to the outside of the desulfurization tower body by the air outlet pipe.

[0010] Furthermore, a fixing ring is fixedly connected to the periphery of the lower end surface away from the center of the desulfurization tower body, and supporting columns are fixedly connected to the two side surfaces of the lower end of the fixing ring away from the center;

[0011] Through the above technical solution, the fixing ring and the support column cooperate with each other, so as to achieve the effect of supporting the desulfurization tower body.

[0012] Furthermore, a demister is fixedly connected to the upper surface of one side of the inner wall of the desulfurization tower body near the center, and a wind cap is fixedly connected to the center of the surface of one side of the inner wall of the desulfurization tower body;

[0013] Through the above technical solution, the moisture and small particles generated in the desulfurization process can be captured and separated by the action of the demister, and when the exhaust gas enters the desulfurization tower under the action of the wind hood, the wind hood will adjust the speed and direction of the airflow to ensure that the airflow can smoothly enter and exit the desulfurization tower, thereby improving the desulfurization effect.

[0014] Furthermore, the collection module includes a collection box, the upper surface of the collection box is fixedly connected with a magnetic attraction layer, and the four corners of the lower surface of the collection box are fixedly connected with displacement devices;

[0015] Through the above technical scheme, the desulfurizer after desulfurization can be collected by the collection box, and the connection strength between the collection box and the desulfurization tower body can be improved by the magnetic absorption layer, and the collection box can be displaced by the displacement device.

[0016] Furthermore, the recovery module includes a recovery box, the bottom surface of the recovery box is fixedly connected to a suction pump, and the output end of the suction pump is fixedly connected to a recovery pipeline;

[0017] Through the above technical solution, the hot water can be recovered after passing through the annular pipeline under the action of the suction pump and the recovery pipeline.

[0018] Furthermore, a control panel is fixedly connected to the surface of one end of the front side of the liquid box body;

[0019] Through the above technical solution, the first water pump and the second water pump can be turned on or off under the control of the control panel.

[0020] The utility model has the following beneficial effects:

[0021] 1. The combined FRP columnar desulfurization tower proposed by the utility model, when the exhaust gas enters the interior of the desulfurization tower body through the air inlet pipe, the desulfurizer is transported to the ejector through the action of the second water pump and the second delivery pipe inside the liquid tank body, and then the ejector is used to desulfurize the harmful components in the exhaust gas inside the desulfurization tower body, so that the harmful components in the exhaust gas are fully contacted with the desulfurizer, so that they form solids and fall onto the filter plate, and then the remaining desulfurizer will fall into the collection box along the filter plate, and then the desulfurized exhaust gas will be separated under the action of the gas-liquid separation cooler, so that the dry gas flows out from the exhaust pipe at the upper end of the gas-liquid separation cooler, and the separated liquid, which also contains the desulfurizer, will fall into the collection box, so as to facilitate the subsequent recycling of the desulfurizer.

[0022] 2. The combined FRP columnar desulfurization tower proposed in the utility model needs to be heated before the desulfurization tower body works because the desulfurization tower body itself is made of FRP. Therefore, the hot water inside the liquid tank body is transported to the annular pipe under the action of the first water pump and the first delivery pipe, and then the surface temperature of the desulfurization tower body is increased under the action of the annular pipe. When the desulfurization tower body works, the hot water delivery is stopped. In this way, the desulfurization tower body can be effectively prevented from having a relatively fast temperature change during operation, which leads to a decrease in the overall strength of the desulfurization tower body, and ultimately leads to a decrease in the overall durability and carrying capacity of the desulfurization tower body.

[0033] The gas-liquid separation cooler 106 can separate the waste gas into gas and liquid. The filter plate 109 can filter the solids formed after the waste gas is desulfurized to prevent the solids from falling into the collection box 201. The support column 105 can support the desulfurization tower body 101.

[0034] Reference Figure 3 The collecting module 2 includes a collecting box 201 , a magnetic layer 202 is fixedly connected to the upper surface of the collecting box 201 , and displacement devices 203 are fixedly connected to the four corners of the lower surface of the collecting box 201 .

When the temperature of the desulfurization tower body 101 reaches a certain level, the first water pump 404 is turned off to stop supplying hot water to the annular pipe 110. The exhaust gas is sucked into the desulfurization tower body 101 by means of the air inlet pipe 102, and then the second water pump 408 is turned on under the action of the control panel 402, so that the desulfurizer is transported to the injector 403 under the cooperation of the second water pump 408 and the second delivery pipe 407, and then the desulfurizer is combined with the harmful substances in the exhaust gas under the action of the injector 403 to form a solid and finally fall into the filter plate 109, and at the same time, the exhaust gas is blown to the gas-liquid separation cooler 106 under the action of the wind hood 108, and the exhaust gas is separated under the action of the gas-liquid separation cooler 106, so that the separated flue gas is discharged from the exhaust pipe 103, and the liquid will fall into the collection box 201 along the inner wall of the desulfurization tower body 101.
