Description

Technical Field

[0001] This utility model relates to the field of hyperbolic cooling tower outlet water filtration equipment, and in particular to a split-type filter screen device for the outlet of a cooling tower pool. Background Technology

[0002] The current cooling tower water tank outlet filter is a flat plate filter. This filter can intercept various impurities in the circulating water, such as floating matter, algae, and broken packing material. When the height difference between the water tank and the water channel before and after the filter exceeds 20cm (because most of the filter holes are blocked, resulting in a reduction in water flow), the flat plate filter needs to be lifted out for cleaning.

[0003] Then, because the filter screen is a flat plate structure, some debris will fall off the flat plate filter screen during the process of lifting the filter screen. In addition, the cooling tower water tank outlet lacks interception function during the filter screen cleaning process, which will cause impurities to be brought into the system, affecting equipment components such as circulating pumps and heat exchange equipment. If impurities enter the heat exchanger, they will adhere to the surface of the heat exchange tubes, reduce heat exchange efficiency, increase energy consumption, and may even cause the heat exchange tubes to be blocked, affecting the normal operation of the equipment. Utility Model Content

[0004] This utility model provides a split-type filter screen device for the outlet of a cooling tower water tank, which solves the problem of impurities falling off during cleaning. The bottom mesh plate traps impurities, preventing them from falling off when the water is lifted out. The split-type filter screen unit can reduce the number of impurities entering the system during the filter screen cleaning process, and can protect equipment connected to the cooling tower outlet water, heat exchangers, etc., and extend the equipment operation cycle.

[0005] This utility model is achieved through the following technical solution:

[0006] A split-type filter screen device for the outlet of a cooling tower pool includes a cover plate horizontally installed at the outlet of the cooling tower pool, the cover plate being higher than the water level at the outlet of the cooling tower pool.

[0007] Multiple filter units that can be raised and lowered are slidably connected to the cover plate, and the multiple filter units are distributed along the length direction of the cover plate;

[0008] The filter unit includes two vertically distributed side screens, with one vertical side of the two side screens connected together as one unit. The two side screens are distributed at an angle, and the opening of the angle between the two side screens faces the cooling tower pool.

[0009] Multiple horizontally distributed bottom mesh plates are provided between the two side mesh plates along the height direction. The top of the filter unit is connected to a top plate, and the top plate is provided with lifting lugs for easy connection with lifting equipment.

[0010] Furthermore, the side mesh panel includes a rectangular frame, within which a stainless steel mesh is fitted;

[0011] A vertically distributed frame is fixed to the other vertical side of the two side panels.

[0012] Furthermore, the bottom mesh plate is a stainless steel plate with uniformly perforated surfaces, and the outer edge of the bottom mesh plate is welded to the frame of the two side mesh plates as a whole.

[0013] Furthermore, the two side mesh plates are distributed at a 90° angle, and the cover plate has a groove that matches the outer contour of the filter unit.

[0014] Furthermore, the number of filter units is 3-5; in each filter unit, the number of bottom mesh plates is 6-8.

[0015] Furthermore, the overall height of the filter unit is 2000-3000mm and the overall width is 600-1000mm.

[0016] The beneficial effects achieved by this utility model compared with the prior art are as follows:

[0017] 1. Multiple filter screen units that can be raised and lowered are slidably connected on the cover plate. Each filter screen unit includes two vertically distributed side screen plates. One vertical side of the two side screen plates is connected together as one unit. The two side screen plates are distributed at an angle. Multiple horizontally distributed bottom screen plates are provided between the two side screen plates along the height direction.

[0018] When all filter units are located at the water tank outlet, the side screens can intercept flowing debris. When a filter unit needs to be cleaned and lifted, the bottom screen prevents the debris intercepted by the side screens from falling into the water during the lifting process. The split-type filter units can reduce the amount of debris entering the system during filter cleaning, protect equipment connected to the cooling tower outlet water, heat exchangers, etc., and extend the equipment's operating cycle.

[0019] 2. Multiple filter units are designed as separate units, allowing for group cleaning and reducing the risk of debris entering the system during traditional filter cleaning processes when all filters are lifted.

[0020] 3. The top plate is equipped with lifting lugs for easy connection with lifting equipment, which makes it easier to move the filter screen during installation and cleaning, reducing manpower consumption and operation difficulty;

[0021] 4. The bottom mesh plate is welded to the frame to form a supporting skeleton for the filter unit, increasing the overall sturdiness. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] In the description of the utility model, it should be understood that the terms "front", "rear", "up", "down", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] The water depth at the outlet of the cooling tower pool is approximately 2 meters. To filter the water, a steel walkway will be constructed across the water surface at the outlet. This walkway will filter impurities from the water, such as... Figures 1-3 As shown in the figure, this embodiment discloses a split-type filter screen device for the outlet of a cooling tower pool, which mainly includes a cover plate 1 and multiple filter screen units. The cover plate 1 is 3200mm long and 300mm wide. The cover plate 1 is fixed to the passage plate by bolt assembly or welding, so that the cover plate 1 can be installed horizontally at the outlet position of the cooling tower pool. In this embodiment, the number of filter screen units is 4.

[0029] The filter unit includes two vertically distributed side mesh plates 2. Each side mesh plate 2 includes a rectangular frame, within which a 10*10mm rectangular stainless steel mesh is installed. The two side mesh plates 2 are connected together along one vertical side, forming a 90° angle. The opening at the angle of the two side mesh plates 2 faces the cooling tower pool. To improve stability, a vertically distributed frame 6 is fixed to the other vertical side of the two side mesh plates 2 by binding or welding. The frame 6 can be made of stainless steel angle steel. Since the water depth at the outlet of the cooling tower pool is approximately 2m, in this embodiment, the overall height of the filter unit is 2200mm and the overall width is 800mm.

[0030] Six horizontally distributed bottom mesh plates 3 are set between the two side mesh plates 2 along the height direction. The spacing between adjacent bottom mesh plates 3 is 360mm. The bottom mesh plates 3 are made of stainless steel plate with a thickness of δ=6mm. φ=10mm round holes are evenly opened on the bottom mesh plates 3. The center-to-center distance between adjacent round holes is 30mm to ensure the rigidity of the bottom mesh plates 3. The bottom mesh plates 3 are generally right-angled triangles. The two right-angled sides are welded to the frame of the two side mesh plates 2 to form the supporting skeleton of the filter unit, mainly to prevent debris from falling off during the lifting process of the filter unit.

[0031] A top plate 4 is connected to the top of the filter unit, and lifting lugs 5 are welded onto the top plate 4 for easy connection with lifting equipment. The lifting lugs 5 are preferably made of bent round steel. The lifting lugs make it easier to move the filter during installation and cleaning, reducing manpower consumption and operation difficulty.

[0032] To filter the water, four filter screen units need to be evenly distributed along the length of cover plate 1. Cover plate 1 has slots that match the outer contour of the filter screen units, allowing them to slide and connect within these slots and move up and down relative to each other. A 1cm gap should be maintained between the filter screen units and cover plate 1 to prevent jamming during cleaning; however, the gap should not be too large, as this could affect system operation.

[0033] The specific working principle of the split-type filter screen device at the outlet of the cooling tower pool described in this embodiment is as follows:

[0034] When all the filter units are located at the water tank outlet, they are arranged in a straight line, and the side mesh panels can intercept the flowing debris.

[0035] When the height difference between the water level in the tanks and the water channel before and after a filter unit exceeds 20cm, the corresponding filter unit needs to be cleaned. Then, the filter unit is lifted using conventional lifting equipment (such as a crane). During the lifting process, the bottom screen plate prevents impurities intercepted by the side screen plates from falling into the water. Since it is not necessary to lift the entire filter unit out of the water, the split-type filter unit can reduce the amount of impurities entering the system during the filter cleaning process. It can protect equipment connected to the cooling tower outlet water, heat exchangers, etc., and extend the equipment operation cycle.
