Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to a desulfurization tower liquid cooling device. Background Art

[0002] The desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. The desulfurization tower was originally built with granite and was the most widely used. The SO2 absorption and purification process treats low-concentration SO2 flue gas with a considerable amount of flue gas, which requires continuous and efficient purification of the flue gas in an instant. Therefore, the chemical reaction in which SO2 participates should be an extremely fast reaction. Their membrane conversion coefficient is large and the reaction occurs in the membrane. Therefore, it is more appropriate to use an absorption tower with a continuous gas phase, high turbulence and a large phase interface as a desulfurization tower and desulfurization dust collector. Usually, spray towers, packed towers, and spray towers are used. , plate towers, Venturi absorption towers, etc. can meet these requirements. Among them, the spray tower is one of the most widely used desulfurization tower types. The spray tower has the advantages of simple structure and mature and reliable technology. It is widely used in large power plants and small and medium-sized low-sulfur flue gas treatment; for high-sulfur flue gas treatment, the non-ferrous industry mainly uses pneumatic emulsification desulfurization towers, multi-layer spray towers, etc., which use the principle of water film desulfurization and dust removal, also known as granite water film desulfurization dust collector, or granite water film desulfurization dust collector. The common main equipment in the desulfurization system is absorption tower, flue, chimney, desulfurization pump, booster fan and other main equipment.

[0003] When the current desulfurization tower is in use, the desulfurization liquid will react with the sulfide in the exhaust gas to generate sulfuric acid and a large amount of heat. The high temperature will make the desulfurization work of the desulfurization tower not thorough enough, thereby increasing the cost of the desulfurization work. Utility Model Content

[0004] In order to solve the problem of excessively high temperature in a desulfurization tower mentioned in the above background technology, the purpose of the utility model is to provide a desulfurization tower liquid cooling device.

[0005] To achieve the above object, the utility model provides the following technical solutions: a desulfurization tower liquid cooling device, comprising a mounting base plate, a fixing bracket is fixedly mounted on the mounting base plate, a plurality of fixing hoops arranged in a linear array are fixedly mounted on the fixing bracket, and a liquid cooling tank is fixedly mounted in the fixing hoop;

[0007] Preferably, a first water inlet pipe is installed at one end of the cooling spiral plate, and a first water outlet pipe is installed at the other end of the cooling spiral plate. The first water inlet pipe and the first water outlet pipe respectively pass through corresponding openings and extend into the cavity.

When in use, the desulfurization liquid enters the cooling spiral plate through the first water inlet pipe, and then is discharged from the cooling spiral plate through the first water outlet pipe. The cooling liquid enters the tank body through the second water inlet pipe, and then is discharged from the tank body through the second water outlet pipe. The cooling spiral plate divides the interior of the tank body into spiral channels. When the cooling liquid passes through the spiral channels, the temperature of the desulfurization liquid in the cooling desulfurization plate can be effectively reduced.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 6 As shown, a desulfurization tower liquid cooling device provided in this embodiment includes a mounting base plate 101, a fixed bracket 102 is fixedly mounted on the mounting base plate 101, a plurality of fixed hoops 103 are fixedly mounted on the fixed bracket 102, and a liquid cooling tank 200 is fixedly mounted inside the fixed hoop 103. When the current desulfurization tower is in use, the desulfurization liquid will react with the sulfide in the exhaust gas to generate sulfuric acid and a large amount of heat. The present application can cool the desulfurization liquid in the desulfurization tower through the liquid cooling tank 200.

[0025] The liquid cooling tank 200 includes a tank body 201, in which a cooling spiral plate 202 is installed. A cavity 205 is provided on the inner side of the cooling spiral plate 202. Openings 204 are provided at both ends of the cooling spiral plate 202, and the openings 204 are connected to the cavity 205. A plurality of heat dissipation fins 203 are installed on the cooling spiral plate 202. The heat dissipation fins 203 can effectively increase the heat exchange rate between the cooling liquid and the desulfurization liquid, thereby greatly improving the cooling speed of the desulfurization liquid.

[0026] Furthermore, referring to an embodiment of the utility model, corresponding drainage grooves can be opened on the heat dissipation fin plate 203, thereby increasing the contact area between the cooling spiral plate 202 and the coolant, and thus increasing the heat exchange rate between the cooling liquid and the desulfurization liquid, thereby greatly improving the cooling speed of the desulfurization liquid.

[0027] One end of the cooling spiral plate 202 is equipped with a first water inlet pipe 104, and the other end of the cooling spiral plate 202 is equipped with a first water outlet pipe 105. The first water inlet pipe 104 and the first water outlet pipe 105 respectively pass through the corresponding openings 204 and extend to the inside of the cavity 205. The cavity 205 is a spiral-shaped chamber. A water pump 106 is fixedly installed on the mounting base 101.

[0029] It should be noted that the utility model can lead the desulfurization liquid in the desulfurization tower out of the desulfurization tower for cooling, which can effectively reduce the temperature in the desulfurization tower and prevent the large amount of heat generated in the desulfurization operation from affecting the desulfurization work. When in use, the desulfurization liquid enters the cooling spiral plate 202 through the first water inlet pipe 104, and then discharges the cooling spiral plate 202 through the first water outlet pipe 105. The cooling liquid enters the tank body 201 through the second water inlet pipe 107, and then discharges the tank body 201 through the second water outlet pipe 108. The cooling spiral plate 202 divides the interior of the tank body 201 into spiral channels, and the cooling liquid passes through the spiral channel. The shaped channel can effectively reduce the temperature of the desulfurization liquid in the cooling desulfurization plate. A plurality of spiral heat dissipation fins 203 are installed on the cooling spiral plate 202. The heat dissipation fins 203 can effectively increase the heat exchange rate between the cooling liquid and the desulfurization liquid, thereby greatly improving the cooling rate of the desulfurization liquid. A spiral rod 206 is installed in the cavity 205, and a plurality of irregular spheres 207 are fixedly installed on the spiral rod 206. The irregular spheres 207 make the desulfurization liquid form irregular turbulence in the cavity 205, thereby increasing the heat exchange rate between the cooling liquid and the desulfurization liquid, thereby improving the cooling rate of the desulfurization liquid in the present application.
