Abstract
Description
Technical Field
[0001] This utility model relates to the field of coil heat exchanger technology, specifically a full exhaust static heat exchanger. Background Technology
[0002] Heat exchangers are key equipment for heat transfer in the industrial field. Their core function is to transfer heat from high-temperature fluids to low-temperature fluids through solid walls or direct contact. They are widely used in industries such as chemical, petroleum, power, and food. However, existing heat exchangers often require welding the cooling coils to the internal structure of the heat exchanger during installation. This is not only inconvenient to operate, but also occupies internal space of the heat exchange tubes and makes it very inconvenient to replace the cooling coils later. Therefore, a full-exhaust static heat exchanger is provided. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a full exhaust static heat exchanger to solve the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a full exhaust static heat exchanger, comprising a heat exchanger shell, a flange cover installed on the top of the heat exchanger shell, a sealing gasket provided at the connection between the flange cover and the heat exchanger shell, a medium inlet pipe and a cooling water drain pipe installed on the top of the flange cover, a medium outlet pipe, a cooling water inlet pipe and a drain pipe installed at the bottom of the heat exchanger shell, and a cooling coil installed inside the heat exchanger shell, one end of the cooling coil being connected to the medium inlet pipe and the other end of the cooling coil being connected to the medium outlet pipe.
[0005] As a preferred embodiment of this utility model, a mounting bracket is welded onto the heat exchanger shell.
[0006] As a preferred embodiment of this utility model, a ball valve is installed on the drain pipe.
[0007] In a preferred embodiment of this invention, the flange cover is fixedly connected to the flange at the top of the heat exchanger shell by bolts and nuts.
[0008] In a preferred embodiment of this invention, both the cooling water drain pipe and the cooling water inlet pipe are connected to the heat exchanger shell.
[0009] As a preferred embodiment of this utility model, the drain pipe is welded to the bottom of the heat exchanger shell.
[0010] Compared with the prior art, the beneficial effects of this utility model are: the cooling coil of the heat exchanger is set inside the heat exchanger, and both ends of the cooling coil are fixedly connected to the medium inlet and outlet pipes to fix the cooling coil, so that the cooling coil does not need to be welded inside the heat exchanger. This not only makes disassembly and assembly convenient, but also increases the internal space of the heat exchanger. The entire heat exchange coil is not welded in the middle, which allows the medium to flow smoothly with low resistance. It can completely drain static water, and the high and low pressure are sealed separately, which is highly reliable. Attached Figure Description

[0014] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0015] Example: Please refer to Figure 1-2 This utility model provides a technical solution: a full exhaust static heat exchanger, including a heat exchanger shell 1, a flange cover 2 installed on the top of the heat exchanger shell 1, a sealing gasket 10 provided at the connection between the flange cover 2 and the heat exchanger shell 1, a medium inlet pipe 7 and a cooling water drain pipe 8 installed on the top of the flange cover 2, a medium outlet pipe 5, a cooling water inlet pipe 6 and a drain pipe 11 installed at the bottom of the heat exchanger shell 1, a cooling coil 9 installed inside the heat exchanger shell 1, one end of the cooling coil 9 connected to the medium inlet pipe 7, and the other end of the cooling coil 9 connected to the medium outlet pipe 5. The medium enters the interior of the cooling coil 9 through the medium inlet pipe 7, and after heat exchange through the cooling coil 9, it is transported to the medium outlet pipe 5 for discharge.
[0016] A mounting bracket 3 is welded onto the heat exchanger shell 1 to facilitate installation and use by workers.
[0017] A ball valve 4 is installed on the drain pipe 11 to control the drainage of liquid from the drain pipe 11.
[0018] The flange cover 2 is fixedly connected to the flange on the top of the heat exchanger shell 1 by bolts and nuts.
[0019] Both the cooling water drain pipe 8 and the cooling water inlet pipe 6 are connected to the heat exchanger shell 1. Cooling water enters the heat exchanger shell 1 through the cooling water inlet pipe 6 and is then discharged through the cooling water drain pipe 8, thereby realizing the heat exchange operation on the cooling coil 9.
[0020] The drain pipe 11 is welded to the bottom of the heat exchanger shell 1.
[0021] Working principle: A full exhaust static heat exchanger has a cooling coil 9 installed inside the heat exchanger shell 1. One end of the cooling coil 9 is fixedly connected to the medium inlet pipe 7, and the other end is fixedly connected to the medium outlet pipe 5, thus fixing the cooling coil 9 inside the heat exchanger shell 1. Moreover, the cooling coil 9 does not need to be welded inside the heat exchanger shell 1, ensuring smooth medium flow, low resistance, and achieving full exhaust static heat exchange. The sealing gasket 10 is used to achieve sealing, preventing leakage and ensuring high reliability. The heat exchanger shell 1 is installed by a mounting bracket 3 welded to the periphery, facilitating construction operations for workers.
[0022] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
