Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization, in particular to a desulfurization device used for environmental protection and energy saving. Background Art

[0002] Desulfurization equipment is used to remove sulfides such as sulfur dioxide produced during the combustion of fuel. Common desulfurization equipment includes flue gas desulfurizers, wet desulfurization equipment and dry desulfurization equipment. Flue gas desulfurizers refer to equipment that converts sulfides in coal or fuel oil into non-volatile compounds through a series of chemical reactions, thereby achieving the purpose of reducing sulfur dioxide emissions. Wet desulfurization equipment achieves desulfurization by bringing flue gas into contact with a liquid that can absorb sulfur dioxide, so that the sulfide is absorbed and converted into sulfuric acid.

[0003] At present, the existing device (such as patent number: CN205073869U) discloses a "desulfurization equipment". The device can make the spray water spirally spray inside the shell by evenly distributing the nozzles on the convex edge extending spirally along the axial direction of the shell, so as to stir the airflow to flow in a spiral shape, so that the flue gas and the water mist are fully in contact, and the steam trap separates the water in the exhaust gas, thereby achieving a good dust removal and desulfurization effect.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when the device is applied to the sulfur gas generated by combustion, since when the sulfide burns, the heat energy generated by the combustion reaction will be released, and this heat energy will be absorbed by the sulfur gas, and then when the sulfur gas flows into the smoke inlet pipe, the heat will be absorbed by the smoke inlet pipe, but the device cannot recycle the heat brought by the sulfur gas to increase the temperature of the water mist used for desulfurization of the device, and since the desulfurization rate of water mist at room temperature is slow, the desulfurization rate needs to be improved. Utility Model Content

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A desulfurization device for environmental protection and energy saving comprises a desulfurization tower and a storage tank, wherein the storage tank is located on the side wall of the desulfurization tower, a liquid inlet pipe is arranged on the side wall of the storage tank, a delivery pump is fixedly installed on the upper end of the storage tank, a liquid outlet pipe is arranged between the side wall of the desulfurization tower and the alkali liquid outlet of the liquid outlet pipe, a liquid suction pipe is arranged between the alkali liquid inlet of the delivery pump and the storage tank, and a smoke inlet groove is opened through the inside of the desulfurization tower;

[0010] A heat conduction mechanism is fixedly installed on the surface of the smoke inlet groove;

[0011] The heat conduction mechanism includes a smoke inlet pipe, and a first heat insulation layer and a second heat insulation layer are fixedly installed on the surface of the smoke inlet pipe respectively. The heat conduction mechanism also includes a rectangular heat conductive sleeve, an L-shaped heat conductive block, a heat conductive strip, and a heat insulation sleeve. The rectangular heat conductive sleeve is located on the surface of the smoke inlet groove, and the rectangular heat conductive sleeve is fixedly installed with the smoke inlet groove.

[0012] Preferably: the rectangular thermally conductive sleeve is located between the first thermal insulation layer and the second thermal insulation layer, the L-shaped thermally conductive block is located between the rectangular thermally conductive sleeve and the storage tank, the L-shaped thermally conductive block is fixedly installed with the rectangular thermally conductive sleeve and the storage tank, the L-shaped thermally conductive block is partially located inside the storage tank, and each group of thermally conductive strips is located at the upper end of the L-shaped thermally conductive block.

[0013] Preferably: each group of the thermally conductive strips is fixedly mounted on the L-shaped thermally conductive block, each of the thermally conductive strips is located inside the storage tank, the thermal insulation sleeve is located on the surface of the rectangular thermally conductive sleeve and the L-shaped thermally conductive block, and the thermal insulation sleeve is fixedly mounted on the rectangular thermally conductive sleeve and the L-shaped thermally conductive block.

[0014] (III) Beneficial effects

[0015] 1. By setting up a heat conduction mechanism, when the sulfide burns, it will release the heat energy generated by the combustion reaction. This heat energy will be absorbed by the sulfur gas, causing its temperature to rise. Then, when the sulfur gas flows into the smoke inlet pipe, the heat will be absorbed by the smoke inlet pipe, and the rectangular heat conduction sleeve and the L-shaped heat conduction block will conduct the heat to the storage tank to heat the alkali solution in the storage tank, thereby achieving the effect of environmental protection and energy saving;

[0016] Second, by arranging a plurality of heat-conducting strips on the L-shaped heat-conducting block, the heat-conducting contact surface between the alkali liquid in the storage tank and the heat-conducting mechanism can be increased, thereby improving the overall heat-conducting efficiency of the device. In addition, heating can increase the reaction rate, making the alkali liquid react with the sulfide in the flue gas faster. This is because heating increases the thermal kinetic energy of the alkali liquid molecules, causing them to react more quickly with the sulfide in the flue gas, thereby increasing the reaction rate.

[0024] The embodiment of the present application effectively solves the technical problem that the desulfurization rate of the existing device needs to be improved by providing a desulfurization device for environmental protection and energy saving. By arranging a heat conduction mechanism, when the sulfide burns, the heat energy generated by the combustion reaction will be released, and the heat energy will be absorbed by the sulfur gas, causing its temperature to rise, so that when the sulfur gas flows into the smoke inlet pipe, the heat will be absorbed by the smoke inlet pipe, and the rectangular heat conductive sleeve and the L-shaped heat conductive block are used to conduct the heat to the storage tank to heat the alkali solution in the storage tank, thereby achieving the effect of environmental protection and energy saving. By arranging a plurality of heat conductive strips on the L-shaped heat conductive block, the heat conductive contact surface between the alkali solution in the storage tank and the heat conduction mechanism can be increased, thereby improving the overall heat conduction efficiency of the device, and heating can increase the reaction rate, so that the alkali solution reacts with the sulfide in the flue gas faster. This is because heating increases the thermal kinetic energy of the alkali solution molecules, causing them to react with the sulfide in the flue gas more quickly, thereby increasing the reaction rate.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the desulfurization rate of the existing device needs to be improved. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a desulfurization device for environmental protection and energy saving, comprising a desulfurization tower 11 and a storage tank 12, the storage tank 12 is located on the side wall of the desulfurization tower 11, a liquid inlet pipe 13 is provided on the side wall of the storage tank 12, a delivery pump 14 is fixedly installed on the upper end of the storage tank 12, a liquid outlet pipe 15 is provided between the side wall of the desulfurization tower 11 and the alkali liquid outlet of the liquid outlet pipe 15, a liquid suction pipe 16 is provided between the alkali liquid inlet of the delivery pump 14 and the storage tank 12, and a smoke inlet groove 17 is opened through the desulfurization tower 11;

[0028] A heat conduction mechanism is fixedly installed on the surface of the smoke inlet slot 17;

[0029] The heat conduction mechanism includes a smoke inlet pipe 18, on the surface of which a first heat insulation layer 19 and a second heat insulation layer 21 are fixedly installed. The heat conduction mechanism also includes a rectangular heat conductive sleeve 22, an L-shaped heat conductive block 23, a heat conductive strip 24, and a heat insulating sleeve 25. The rectangular heat conductive sleeve 22 is located on the surface of the smoke inlet groove 17, and the rectangular heat conductive sleeve 22 is fixedly installed with the smoke inlet groove 17. By setting the heat conduction mechanism, when the sulfide burns, the heat energy generated by the combustion reaction will be released, and the heat energy will be absorbed by the sulfur gas, causing its temperature to rise, and then when the sulfur gas flows into the smoke inlet pipe 18, the heat will be absorbed by the smoke inlet pipe 18, and the rectangular heat conductive sleeve 22 and the L-shaped heat conductive block 23 will be used to conduct the heat to the storage tank 12 to heat the alkali solution in the storage tank 12, thereby achieving an environmental protection and energy-saving effect.

[0030] The rectangular heat-conducting sleeve 22 is located between the first heat-insulating layer 19 and the second heat-insulating layer 21, the L-shaped heat-conducting block 23 is located between the rectangular heat-conducting sleeve 22 and the storage tank 12, the L-shaped heat-conducting block 23 is fixedly installed with the rectangular heat-conducting sleeve 22 and the storage tank 12, and the L-shaped heat-conducting block 23 is partially located inside the storage tank 12, each group of heat-conducting strips 24 is located at the upper end of the L-shaped heat-conducting block 23, each group of heat-conducting strips 24 is fixedly installed with the L-shaped heat-conducting block 23, and each heat-conducting strip 24 is located inside the storage tank 12, and the heat-insulating sleeve 25 is located between the rectangular heat-conducting sleeve 22 and the L The surface of the L-shaped heat-conducting block 23 is provided with a heat-insulating sleeve 25, and is fixedly installed with the rectangular heat-conducting sleeve 22 and the L-shaped heat-conducting block 23. By arranging a plurality of heat-conducting strips 24 on the L-shaped heat-conducting block 23, the heat-conducting contact surface between the alkali solution in the storage tank 12 and the heat-conducting mechanism can be increased, thereby improving the overall heat conduction efficiency of the device. In addition, heating can increase the reaction rate, so that the alkali solution reacts with the sulfide in the flue gas faster. This is because heating increases the thermal kinetic energy of the alkali solution molecules, causing them to react with the sulfide in the flue gas more quickly, thereby increasing the reaction rate.

[0031] Working principle:

[0032] The first step is to start the delivery pump 14 when in use. At this time, the delivery pump 14 will use the delivery pump 14 to extract the alkali solution in the storage tank 12 and deliver it to the spray system of the desulfurization tower 11 through the liquid outlet pipe 15. At this time, the desulfurization tower 11 will spray out the alkali solution at room temperature, and then the sulfur gas generated by the sulfide in the combustion exhaust gas will be delivered to the inside of the smoke inlet tank 17 through the smoke inlet pipe 18 (the smoke inlet pipe 18 is made of iron);

[0033] In the second step, since it is sulfur gas generated during combustion, the sulfur gas will carry more heat (when sulfide burns, it will release heat energy generated by the combustion reaction, which will be absorbed by the sulfur gas, causing its temperature to rise, thereby carrying more heat). At this time, the heat will be transferred to the inner wall of the smoke inlet pipe 18. At this time, due to the material of the rectangular heat-conducting sleeve 22 (the rectangular heat-conducting sleeve 22, the L-shaped heat-conducting block 23 and the heat-conducting strip 24 are all made of copper. The electronic structure of copper makes it an excellent conductor. Electrons can move freely in copper and carry energy. When the temperature difference causes the thermal motion of electrons inside the copper to increase, these freely moving electrons are excited, causing heat to spread rapidly in the copper), the rectangular heat-conducting sleeve 22 will absorb heat and conduct it to the L-shaped heat-conducting block 23 and the heat-conducting strip 24, so that the L-shaped heat-conducting block 23 and the heat-conducting strip 24 heat the alkali solution inside the storage tank 12, thereby heating the alkali solution sprayed by the spray system inside the desulfurization tower 11.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
