Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for a thermal power plant which is easy to disassemble and clean. Background Art

[0002] When thermal power stations use coal, oil and combustible gas as energy sources to generate electricity, they will produce wastewater containing high concentrations of sulfur and various chemicals. These wastewaters mainly come from the washing of ash, dust removal and drainage from industrial activities. If they are discharged directly into the natural water environment without treatment, it will easily cause pollution problems. Therefore, these wastewaters must be purified with the help of sewage treatment facilities. Although the power plant wastewater treatment facilities widely used in the market are generally simple in design, they show many functional deficiencies in actual operation and are in urgent need of optimization and upgrading. For example, common problems include but are not limited to: the filter plates in the internal sedimentation area are fixed and difficult to disassemble for cleaning, and lack a design that is easy to clean; when the dosing area introduces wastewater into the sedimentation area, it generally flows directly through the opening, resulting in easy accumulation of particles at the bottom of the dosing area, making cleaning difficult and unable to effectively adsorb the bottom sediment; and impurity deposits at the bottom of the sedimentation area are difficult to clean quickly, and it is not convenient to quickly rinse the sediment. These problems point to the direction in which current wastewater treatment technology needs to be improved.

[0003] Among them, a thermal power plant wastewater treatment device with application number CN202220294558.5, which is easy to disassemble and clean, solves the above-mentioned technical problems and discloses technical key points, including a box body, the top of one side of the box body is fixedly connected to a water outlet pipe, the top of the other side of the box body is fixedly connected to a water inlet pipe, a partition is vertically welded to one side of the bottom end of the inside of the box body, an inner hole is provided inside the partition, a support plate is fixedly connected to the bottom end of one side of the box body, and a structure easy to disassemble and clean is provided inside the box body, and the structure easy to disassemble and clean includes four groups of concave grooves, the four groups of concave grooves are respectively welded to the front and rear ends of the inside of the box body, and a plug-in plate is inserted inside between one ends of the concave grooves.

[0004] However, the plug plate in the wastewater treatment device of the thermal power plant, that is, the filter plate, still needs to be connected to the bottom of the pool through water. For the wastewater of the thermal power plant, the launching operation is obviously dangerous, so it needs to be replaced in a way that does not come into contact with the wastewater throughout the process.

[0005] Therefore, a wastewater treatment device for a thermal power plant which is easy to disassemble and clean is proposed to solve or alleviate the above-mentioned problems. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a wastewater treatment device for a thermal power plant which is easy to disassemble and clean.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A wastewater treatment device for a thermal power plant which is easy to disassemble and clean comprises a pool body with an opening on the top surface and a connecting frame for closing the pool body, wherein a plurality of groups of mounting frames are fixedly connected to the bottom surface of the connecting frame, wherein the width of the mounting frame is the same as the inner width of the pool body, wherein an mounting space is formed inside the mounting frame, wherein the mounting space has an inlet and outlet along the width direction of the pool body, wherein a filter plate is embedded in the mounting frame, wherein a connecting ring is fixedly connected to the top surface of the connecting frame, wherein the connecting ring is connected to a chain, and wherein the chain is used to connect to a crane.

[0009] Preferably, a plurality of groups of obliquely arranged reinforcing ribs are fixedly connected to the bottom surface of the connecting frame, the number of the reinforcing ribs in each group is 4, and the 4 reinforcing ribs are all fixedly connected to the inner corners of the bottom surface of the mounting frame.

[0010] Preferably, it also includes a stirring pool connected to the pool body, the stirring pool is connected to an inlet pipe, the end of the pool body away from the stirring pool is connected to an outlet pipe, the top surface of the stirring pool is fixedly connected to a cover, and the cover is provided with a stirring component for stirring the stirring pool.

[0011] Preferably, the stirring assembly includes a driving motor fixedly connected to the cover, a rotating shaft fixedly connected to the output shaft of the driving motor, and an agitator fixedly connected to the rotating shaft.

[0012] Preferably, the connecting frame, the mounting frame, and the reinforcing ribs are all hollow and internally connected to form a weighted space. A pumping assembly is provided on the cover, the pumping assembly is connected to the weighted space and is used to inject fluid. A through hole connected to the weighted space is provided on the bottom surface of the mounting frame.

[0013] Preferably, the pumping assembly includes a self-priming pump fixedly connected to the cover, an electromagnetic three-way valve connected thereto, a water inlet pipe and an air inlet connected to the electromagnetic three-way valve, and a water supply pipe connected to the self-priming pump and the weighted space.

[0014] Preferably, it also includes an aeration pipe, which is arranged on the bottom surface of the pool body and is used to connect to the aerator.

[0015] The utility model has the following beneficial effects:

[0016] When replacing the filter plate, this utility model first ensures that the connecting frame is suspended by using a crane, a chain and a connecting ring, and the weighted space is in an empty state, so as not to generate too much load on the crane. The operator can easily embed the new filter plate into the mounting frame, and then put it into the pool by the crane. After turning on the self-priming pump, the waste water is sucked from the pool body into the weighted space. Although some water will be discharged from the through hole, the water injection volume is so large that no water loss will be felt. The weighted space filled with liquid balances the pressure with the pool body, and the water is still and no longer loses. At this time, the pump is turned off. The frame of this design can be securely fixed in the pool body, ensuring that the filter plate, the mounting frame and the connecting frame are stable and motionless when filtering wastewater, and reinforcing ribs are added to improve the stability and durability of the structure when impacted by water flow.

[0017] When treating wastewater, wastewater and additives are introduced into the mixing tank through the water inlet pipe, where they are fully stirred and spread into the tank body by the agitator driven by the motor. The wastewater then flows through the filter plate to remove impurities and is aerated with the help of the aeration pipe, and finally flows out of the tank body through the outlet pipe.

[0018] When the filter plate needs to be replaced, just open the electromagnetic three-way valve to allow outside air to enter, close the water inlet pipe end, and the gas will enter the weighted space through the pipe. The liquid will be discharged from the through hole under the action of air pressure until space is left. At this time, use the crane to lift the installation frame and the connecting frame, which is not only convenient for replacement, but also will not increase the load on the crane. In this way, the replacement of the filter plate becomes simple and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The wastewater treatment device of a thermal power plant which is easy to disassemble and clean comprises a tank body with an opening on the top surface, a stirring tank 2 connected to the tank body, a connecting frame 701 for closing the tank body, an aeration pipe 102 arranged on the bottom surface of the tank body, the aeration pipe 102 is used to connect to an aerator, a plurality of groups of mounting frames 8 are fixedly connected to the bottom surface of the connecting frame 701, a plurality of groups of obliquely arranged reinforcing ribs 802 are fixedly connected to the bottom surface of the connecting frame 701, the number of each group of reinforcing ribs 802 is 4, and the four reinforcing ribs 802 are all fixedly connected to the inner corner of the bottom surface of the mounting frame 8, The width of the mounting frame 8 is the same as the inner width of the pool body, and an mounting space is formed in the mounting frame 8. The mounting space has an inlet and an outlet along the width direction of the pool body. A filter plate 801 is embedded in the mounting frame 8. A connecting ring is fixedly connected to the top surface of the connecting frame 701, and the connecting ring is connected to a chain 702. The chain 702 is used to connect to a crane. The stirring pool 2 is connected to an inlet pipe 201, and an end of the pool body away from the stirring pool 2 is connected to an outlet pipe 101. A sealing cover 3 is fixedly connected to the top surface of the stirring pool 2, and a stirring component for stirring the stirring pool 2 is provided on the sealing cover 3.

[0024] The stirring assembly comprises a driving motor 4 fixedly connected to the cover 3 , a rotating shaft 5 fixedly connected to the output shaft of the driving motor 4 , and a stirrer 6 fixedly connected to the rotating shaft 5 .

[0025] The connecting frame 701, the mounting frame 8, and the reinforcing ribs 802 are all hollow and internally connected to form a weighted space. A pumping assembly is provided on the cover 3, which is connected to the weighted space and is used to inject fluid. A through hole connected to the weighted space is provided on the bottom surface of the mounting frame 8. The pumping assembly includes a self-priming pump 901 fixedly connected to the cover 3, an electromagnetic three-way valve 902 connected thereto, a water inlet pipe 903 and an air inlet 904 connected to the electromagnetic three-way valve 902, and a water supply pipe 905 connecting the self-priming pump 901 and the weighted space.

[0026] When the filter plate 801 is replaced, the connection frame 701 is first kept in a suspended state by the crane, the chain 702 and the connection ring. In this process, the empty setting in the space is increased, so that the entire connection frame 701 does not bring too much weight to the crane. The operator only needs to insert the filter plate 801 into the installation frame 8 from the inlet and outlet of the installation space to complete the installation of the filter plate 801, and then place the filter plate 801 into the pool body through the crane, and then pump the assembly to start working, and the self-priming pump 901 will suck The wastewater in the pool body enters the weighted space through the water inlet pipe 903, the electromagnetic three-way valve 902, the self-priming pump 901, and the water supply pipe 905 in this order. Water will flow out of the through holes on the bottom of the installation frame 8. However, since the amount of water inflow is much greater than the amount of water outflow, the loss of water cannot be felt. After the weighted space is filled with liquid, the pressure therein is consistent with that in the pool body, and the water remains relatively static and will not flow further. The self-priming pump 901 can be turned off.

In this process, the wastewater additive is introduced into the stirring tank 2 through the water inlet pipe 903, and the driving motor 4 drives the agitator 6 to stir the wastewater and the additive in the stirring tank 2 through the rotating shaft 5, so that it diffuses into the tank body, and then the wastewater is filtered through the filter plate 801 for many times, and the wastewater in the aeration pipe 102 is aerated in the process until it finally leaves through the outlet pipe 101. Pool body, and when the operator needs to replace the filter plate 801, he only needs to open the electromagnetic three-way valve 902 to make the air inlet 904 unblocked and close one end of the water inlet pipe 903, so that the outside air can pass through the electromagnetic three-way valve 902, the self-priming pump 901, and the water supply pipe 905 to enter the weighted space, so that the liquid in the weighted space is accelerated to leave from the through hole under the pressure of air pressure until it reaches a vacant position in the weighted space. At this time, the connecting frame 701 and the mounting frame 8 are hoisted up through the crane, the chain 702, and the connecting ring. In this way, no additional burden is added to the crane.
