Description

Technical Field

[0001] The utility model belongs to the field of wastewater concentration equipment, and particularly relates to a desulfurization wastewater concentration device. Background Art

[0002] The desulfurization wastewater concentration device is a special equipment for treating desulfurization wastewater and concentrating it. In actual use, the desulfurization wastewater concentration device lacks a circulating concentration component. Without the circulating concentration component, the wastewater can only be concentrated once, and the potential of the device cannot be fully exerted. This makes it impossible to remove impurities and salts in the wastewater to the maximum extent, and there is still room for improvement in the concentration of the concentrated wastewater. This is because of the lack of a circulating concentration component. The lack of a circulating concentration component not only causes the above problems, but also the single concentration treatment is easily affected by various factors, such as fluctuations in wastewater composition, changes in treatment conditions, etc., further reducing the concentration effect. This situation not only affects the treatment efficiency and quality of desulfurization wastewater, but also increases the difficulty and cost of subsequent treatment links. Therefore, a new structure needs to be proposed to solve the above technical problems. Content of the Utility Model

[0022] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a desulfurized wastewater concentration device, comprising: a concentration tank 100, a filtration tank 300, a flue gas assembly, and a circulation assembly 200. An outlet pipe 120 is installed on the lower side surface of the concentration tank 100. Two circulation assemblies 200 are symmetrically installed on the outer side surface of the concentration tank 100. A flue gas assembly is installed on the upper side surface of the concentration tank 100. A filtration tank 300 is installed on the outer side surface of the concentration tank 100 through a wastewater pipe 320. A water inlet pipe 310 is installed on the outer side surface of the filtration tank 300 through a filtering member. The circulation assembly 200 includes: a circulation pump 210, a circulation pipe 220, and a first spray head 221. A circulation pipe 220 is installed at the outlet of the circulation pump 210. A first spray head 221 is installed on the outer side surface of the circulation pipe 220. The flue gas assembly includes: an inlet pipe 430, a first flue gas pipe 400, a second flue gas pipe 420, and a flue gas recovery pipe 410. Inlet pipes 430 are symmetrically installed on the outer side surface of the concentration tank 100. A first flue gas pipe 400 is installed on the upper side surface of the concentration tank 100.

[0023] Please refer to Figures 1 to 3 , as the first embodiment of the present utility model: Support legs 110 are installed on the lower side surface of the concentration tank 100. An outlet pipe 120 is installed at the center position of the lower side surface of the concentration tank 100. The bottom inside the concentration tank 100 is in an inverted conical structure. Two circulation pumps 210 are symmetrically installed at the inclined surface of the bottom of the concentration tank 100.

[0024] The inlet of the circulation pump 210 is connected to the inside of the concentration tank 100. The end of the circulation pipe 220 away from the circulation pump 210 penetrates the left and right sides of the outer side surface of the concentration tank 100. A plurality of first spray heads 221 are evenly installed on the outer side surface of the end of the circulation pipe 220 away from the circulation pump 210. One inlet pipe 430 is symmetrically installed on each of the left and right sides of the outer side surface of the concentration tank 100.

[0025] The end of the inlet pipe 430 away from the concentration tank 100 is connected to a gas supply device. Support legs 110 are installed on the lower side surface of the filtration tank 300. A wastewater pipe 320 is installed at the center position of the upper side surface of the filtration tank 300 through a pump.

[0026] The end of the water inlet pipe 310 away from the filtration tank 300 penetrates the outer side surface of the concentration tank 100. The wastewater pipe 320 is in an L-shaped structure. A plurality of second spray heads 321 are evenly installed on the outer side surface of the end of the wastewater pipe 320 away from the filtration tank 300.

[0027] When in use, the user first discharges the filtered wastewater into the interior of the filtration tank 300 through the water inlet pipe 310 in combination with a filtration pipe (the filtration pipe can be an existing filtration product, as long as it can meet the filtration of wastewater, and its working principle and structure will not be elaborated here. Note that after using for a period of time, the filtration pipe needs to be replaced or cleaned to ensure subsequent use). After discharging the wastewater into the filtration tank 300, at this time the user can first start the gas supply device to generate flue gas and then inject the flue gas into the interior of the concentration tank 100 through the gas inlet pipe 430. At this time, when injecting the flue gas, the user can start the pump on the upper surface of the filtration tank 300, and then pump the wastewater into the interior of the wastewater pipe 320 through the pump, and then spray the wastewater in a mist form inside the concentration tank 100 through the spray head two 321 on the outer surface of the wastewater pipe 320. At this time, the flue gas (the flue gas can be the hot waste gas generated by a boiler and an incinerator or the hot gas independently generated by burning coal through other equipment. As for what temperature of the flue gas is used for concentration operation, it needs to be selected according to the actual situation and will not be elaborated here) contacts the wastewater in a mist form, so as to carry out concentration, and then falls to the bottom inside the concentration tank 100. With the concentration effect, the concentrated desulfurized wastewater at the bottom inside the concentration pipe will be more and more. At this time, the user can start the circulation pump 210 on the lower surface of the concentration tank 100 to pump out the concentrated desulfurized wastewater inside the concentration tank 100, and then pump it into the interior of the circulation pipe 220, and then spray the concentrated desulfurized wastewater in a mist form again inside the concentration tank 100 through the spray head two 321 on the outer surface of the circulation pipe 220, and then be concentrated by the flue gas again and fall to the bottom inside the concentration tank 100. After the concentration is completed, at this time the user can open the valve on the outer surface of the discharge pipe 120 to discharge the desulfurized wastewater that has been concentrated and circulated multiple times inside the concentration tank 100. Through the circulation assembly 200, the concentrated desulfurized wastewater inside the concentration tank 100 can be continuously circulated and concentrated, so as to improve the concentration efficiency. Through multiple cycles of concentration, the wastewater can reach a higher concentration, and the resources are fully utilized, and the substances in the wastewater are utilized more thoroughly, reducing waste.

[0028] Please refer to Figures 1 to 3 , as the second embodiment of the present utility model: The spray head one 221 and the spray head two 321 have the same structure. Two water inlet pipes 310 are symmetrically installed on the right side of the outer surface of the filtration tank 300 through the filtration pipe. One end of the water inlet pipe 310 far away from the filtration tank 300 is connected to the wastewater supply device. A smoke pipe one 400 is installed at the central position of the upper surface of the concentration tank 100. Two smoke gas recovery pipes 410 are symmetrically installed at one end of the smoke pipe one 400 far away from the concentration tank 100;

[0029] The two flue gas recovery pipes 410 have the same structure. One end of the two flue gas recovery pipes 410 away from the first flue gas pipe 400 is connected to the outer surface of the intake pipe 430. The upper ends of the two flue gas recovery pipes 410 are equipped with the second flue gas pipe 420. An electronic valve is installed on the outer surface of the second flue gas pipe 420 and the flue gas recovery pipes 410 respectively. The first flue gas pipe 400, the second flue gas pipe 420 and the flue gas recovery pipes 410 are interconnected and connected;

[0030] During use, when the intake pipe 430 injects flue gas into the concentration tank 100 through the gas supply device, the flue gas that has not come into contact with the wastewater will gather upward at this time and enter the flue gas recovery pipe 410 through the first flue gas pipe 400. Since valves are installed on the outer surfaces of the flue gas recovery pipe 410 and the second flue gas pipe 420, the valve on the outer surface of the second flue gas pipe 420 is closed at this time, and the valve on the outer surface of the flue gas recovery pipe 410 is opened. At this time, the flue gas entering the flue gas recovery pipe 410 from the first flue gas pipe 400 will flow into the intake pipe 430, and then the intake pipe 430 will re-discharge the recovered flue gas into the concentration tank 100 for continued use. At this time, if the user does not need to recover the flue gas, the valve on the outer surface of the flue gas recovery pipe 410 is closed at this time, and then the valve on the surface of the second flue gas pipe 420 is opened to discharge the flue gas discharged from the concentration tank 100 from the second flue gas pipe 420. Then the user can connect the second flue gas pipe 420 to the flue gas treatment device to treat the recovered flue gas. Through the control of the user, the unused flue gas is recovered and recycled, thereby improving the energy utilization rate, making full use of the heat energy in the flue gas, reducing energy waste, and reducing costs. It also reduces the generation and consumption of new flue gas and lowers the operating cost.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
