Description

Technical Field:

[0001] The utility model belongs to the technical field of closed cooling towers, and particularly relates to a new tube box type closed cooling tower cooler. Background Art:

[0002] The tube box type closed cooling tower is usually applied to the high-pressure sewage treatment environment, which requires that the branch and manifold pipes of the cooler have sufficient wall thickness to withstand a water pressure of 2.0 MPa.

[0003] In order to enable the branch and manifold pipes to withstand a water pressure of 2.0 MPa, the conventional method is to use a single carbon steel plate as the sealing plate. The larger the area of the single sealing plate, the greater its wall thickness, and the thickness of the whole carbon steel plate can reach 25 mm. This not only increases the material cost, but also has a large weight and is not convenient for disassembly and assembly.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the utility model and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model:

[0005] The purpose of the utility model is to provide a new tube box type closed cooling tower cooler, which reduces the wall thickness while ensuring the pressure bearing capacity of the branch and manifold pipes, thereby overcoming the defects in the above-mentioned prior art.

[0006] To achieve the above purpose, the utility model provides a new tube box type closed cooling tower cooler, which includes an inlet water branch and manifold pipe, an outlet water branch and manifold pipe, a baffle branch and manifold pipe, and a cooling coil; an inlet is arranged on the inlet water branch and manifold pipe, and an outlet is arranged on the outlet water branch and manifold pipe; the water inlet end of the cooling coil is connected to the inlet water branch and manifold pipe, the water outlet end of the cooling coil is connected to the outlet water branch and manifold pipe, and the baffle end of the cooling coil is connected to the baffle branch and manifold pipe, wherein the inlet water branch and manifold pipe and the outlet water branch and manifold pipe are located at the front end of the cooler, and the baffle branch and manifold pipe is located at the rear end of the cooler; the inlet water branch and manifold pipe, the outlet water branch and manifold pipe, and the baffle branch and manifold pipe are all of split structures, wherein the inlet water branch and manifold pipe and the outlet water branch and manifold pipe both include a front sealing plate, a unit front branch and manifold pipe, and a front connecting pipe. The unit front branch and manifold pipes are symmetrically arranged on both sides of the front connecting pipe, and the unit front branch and manifold pipes are connected by the front connecting pipe. The outside of the unit front branch and manifold pipe is sealed by the front sealing plate, and the inside of the unit front branch and manifold pipe is connected to the corresponding cooling coil; the baffle branch and manifold pipe includes a rear sealing plate, a unit rear branch and manifold pipe, and a rear connecting pipe. The unit rear branch and manifold pipes are symmetrically arranged on both sides of the rear connecting pipe, and the unit rear branch and manifold pipes are connected by the rear connecting pipe. The outside of the unit rear branch and manifold pipe is sealed by the rear sealing plate, and the inside of the unit rear branch and manifold pipe is connected to the baffle end of the corresponding cooling coil; through the split inlet water branch and manifold pipe, outlet water branch and manifold pipe, and baffle branch and manifold pipe, the single area of the front sealing plate and the rear sealing plate is halved, and the thickness of the front sealing plate is 10 mm.

[0007] Preferably, in the technical solution, the rear sealing plate includes a frame and a sealing plate. The sealing plate is connected to the unit rear sub-collecting pipe. A frame is provided around the sealing plate, and the sealing plate is fixed to the rear end of the cooler through the frame. The thickness of the sealing plate is 6 mm, and the thickness of the frame is 25 mm, greatly reducing the overall thickness and weight of the rear sealing plate.

[0008] Preferably, in the technical solution, the sealing plate is an arched circular arc structure, and an arc-shaped flow channel is formed in the inner cavity of the sealing plate. Compared with the 90° sudden turn of the rectangular sub-collecting pipe, the arc-shaped flow channel reduces the water flow impact force received.

[0009] Preferably, in the technical solution, the water outlet sub-collecting pipe protrudes from the water inlet sub-collecting pipe, and a drop is formed between the water outlet sub-collecting pipe and the water inlet sub-collecting pipe, which is convenient for disassembly and assembly.

[0010] Compared with the prior art, the present utility model has the following beneficial effects:

[0011] By designing the sub-collecting pipe connected to the cooling coil into a split structure, the area of the sealing plate of a single sub-collecting pipe is greatly reduced. Without affecting the pressure bearing of the sub-collecting pipe, the wall thickness of the sealing plate is greatly reduced, making the overall weight of the sub-collecting pipe greatly reduced and facilitating disassembly and assembly.
