Description

Technical Field

[0001] This application relates to the field of plate cleaning, and particularly to a plate cleaning circulating water system. Background Art

[0002] The plate heat exchanger is a bridge connecting the heat source and users, and is an essential key device in the indirect supply system. The primary high-temperature hot water and the secondary user's warm water are exchanged through it. The core component of the plate heat exchanger is the plate. Since tap water contains a small amount of microorganisms and dust, these two substances will generate black biological slime after heating. The heat resistance coefficient of this biological slime is 6 times that of water scale. When the biological slime in the water passes through the plate heat exchanger, it will adhere to the plate, which greatly reduces the heat conduction efficiency of the plate for the primary and secondary water. Therefore, it is necessary to timely and effectively remove the biological slime on the plate to improve the heating efficiency and reduce energy consumption.

[0003] The existing physical method for removing biological slime on the plate mostly sprays the surface of the plate with a high-pressure water gun at 25 MPa - 30 MPa to peel off the biological slime attached to the plate surface. Using the physical method to clean the plate will not cause pollution to the surrounding environment, but it uses a large amount of water during the cleaning process, resulting in waste of water resources, increased cleaning costs, and does not meet the requirements of energy conservation and environmental protection benefits.

[0026] In addition, in order to better illustrate the present application, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, elements and circuits well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0027] As shown in the figure, the plate cleaning circulating water system includes: a treatment tank 100, a sedimentation tank 200 and a water storage tank 500.

[0028] The water outlet end of the treatment tank 100 is connected to the water inlet end of the sedimentation tank 200 through a pipeline. The water outlet end of the sedimentation tank 200 is connected to the water inlet end of the water storage tank 500 through a pipeline. The water outlet end of the water storage tank 500 is suitable for connection to a high-pressure cleaner. The treatment tank 100 is a tank body structure with an open top. A partition block 110 is arranged in the treatment tank 100. The treatment tank 100 is divided into a diversion area and a sedimentation area by the partition block 110. A first water passing hole 111 is opened on the partition block 110. An inclined diversion platform 120 is arranged in the diversion area. The diversion platform 120 is inclined downward towards the partition block 110, and there is a preset distance between the diversion platform 120 and the partition block 110. A sand baffle 140 is arranged in the sedimentation area. The water outlet end of the treatment tank 100 is opened on one side of the sedimentation area.

[0029] The plate is placed on the flushing platform 700 for flushing. Since the flushing platform 700 is a mesh structure, the water with sand grains, fine soil and biological slime after flushing will enter the treatment tank 100 at the bottom of the flushing platform 700. The diversion area in the treatment tank 100 is used to divert and collect the flushing water into the sedimentation area. A sand baffle 140 is arranged in the sedimentation area. The sand baffle 140 can play a role in blocking sand grains. At the same time, the water flow velocity will gradually decrease when the water passes through the sand baffle 140. The smaller the water flow velocity, the faster the sand grains will precipitate. Multiple sand baffles 140 block layer by layer to make a preliminary precipitation. It is only necessary to regularly clean the sand grains, fine soil and precipitated biological slime in the treatment tank 100.

[0030] The water after preliminary sedimentation enters the sedimentation tank 200 through a pipeline and undergoes at least three - stage sedimentation in the sedimentation tank 200. Each stage of sedimentation is separated by a yielding baffle 210. The notches 211 on the yielding baffle 210 are arranged staggeredly in the width direction, which can increase the sedimentation time of water in the sedimentation tank 200, thereby improving the sedimentation effect. A turning - up plate 220 is arranged on the front side of the notch 211. Here, the front side refers to the front side in the water flow direction. The turning - up plate can block the fine soil and biological slime suspended in the water, preventing them from passing through the notch 211 with the water flow. For water to pass through the notch 211, it must first go down, pass through the bottom of the turning - up plate 220, and then go up to reach the position of the notch 211. At this time, the fine soil and biological slime flow downward with the water flow. Since both the fine soil and biological slime have a certain mass, and the mass of the fine soil is greater than that of the biological slime, when the water turns back upward, the fine soil and part of the biological slime precipitate to the bottom of the sedimentation tank 200 under the action of downward inertia and mass. Due to the relatively high water flow velocity, part of the biological slime with a small mass will enter the secondary sedimentation tank 200 with the water flow. As the water flow velocity decreases gradually, the biological slime will complete sedimentation before the outlet of the tertiary sedimentation tank 300. In addition, a sludge pipe 230 is arranged at the bottom of the sedimentation tank 200. The sludge pipe 230 extends from the inner bottom of the sedimentation tank 200 to the outside and is connected with a sludge pump for discharging the sludge deposited at the bottom of the sedimentation tank 200. The sludge pipe 230 passes through the baffle 210, and a flange is installed on one side of the baffle 210. During the operation of the device, blind plates are used to block each stage of the sedimentation tank 200, and the flange is opened for sewage discharge during cleaning.

[0031] The supernatant after sedimentation enters the clear - water tank 300. The supernatant is stored in the clear - water tank 300 and undergoes final sedimentation to ensure that the amount of sediment passing through the reuse pump 400 is small enough. The water inlet of the reuse pump 400 is installed at the 1 / 2 position in the height direction of the clear - water tank 300, and the suction port faces upward. This can ensure that the negative pressure near the suction port during water absorption will not suck impurities into the water storage tank 500, and at the same time, it can avoid damaging the reuse pump 400. The reuse pump 400 pumps the clear water into the water storage tank 500 for storage. The water storage tank 500 is used to connect to a high - pressure cleaning machine to provide water for the high - pressure cleaning machine to wash the plates.

The partition block 110 is used to separate the diversion area and the sedimentation area of ​​the treatment pool 100, and the first water hole 111 on the partition block 110 is used to connect the diversion area and the sedimentation area, and can introduce water from the diversion area into the sedimentation area.

The guide platform 120 is high on the side away from the partition block 110, and gradually decreases toward the end where the partition block 110 is provided, thereby achieving the effect of diverting and collecting sewage.

[0037] In a possible implementation, the sedimentation tank 200 is a tank structure with a hollow interior.

[0038] In a possible implementation, it further includes a flushing platform 700.

The yield groove 150 is matched with the flushing platform 700 for clamping the flushing platform 700 in the yield groove 150 so that it is not easy to move.

[0039] In a possible implementation, it further includes a clean water tank 300. A water collecting trough is arranged at the bottom of the clean water tank 300.
