Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, and particularly relates to a connection structure between a tube sheet and a tube box under high-temperature conditions on the tube side of a cooler. Background Technique

[0002] A cooler is a type of heat exchange equipment used to cool fluids. Usually, water or air is used as the coolant to remove heat. It can be mainly divided into shell-and-tube coolers, plate coolers, and air-cooled coolers. Coolers are heat exchange devices commonly used in industrial sectors such as metallurgy, chemical industry, energy, transportation, light industry, and food.

[0003] In the structural design of heat exchangers under high-temperature conditions, the traditional connection structures between the tube box and the tube sheet all adopt flange connection structures sealed with metal wound gaskets or metal gaskets, or the form of segmental welding between the tube sheet and the tube box. When the inlet temperature of the tube-side medium is too high and the temperature difference between the inlet and outlet is too large, the sealing reliability of the tube side cannot be guaranteed. At the same time, heat conduction occurs between the hot and cold sections of the tube-side medium at the partition ribs, reducing the heat transfer effect of the heat exchanger and increasing the investment cost of the heat exchanger. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connection structure between a tube sheet and a tube box under high-temperature conditions on the tube side of a cooler, so as to solve the problems in the above-mentioned background technique that for the connection structure between the tube sheet and the tube box under high-temperature conditions on the tube side of the cooler, when the temperature difference between the inlet and outlet is too large, the sealing reliability of the tube side cannot be guaranteed, and at the same time, heat conduction occurs between the hot and cold sections of the tube-side medium at the partition ribs, reducing the heat transfer effect of the heat exchanger and increasing the investment cost of the heat exchanger.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A connection structure between a tube sheet and a tube box under high-temperature conditions on the tube side of a cooler, including a tube box, one side of the tube box is provided with a tube sheet, and partition ribs are fixed on the side of the tube sheet close to the tube box.

[0006] Preferably, the tube box is of a cylindrical structure, and the tube box and the tube sheet are connected by welding.

[0007] Preferably, the tube box is provided with a high-temperature inlet and a low-temperature outlet, and an external groove is opened between the high-temperature inlet and the low-temperature outlet of the tube box.

[0008] Preferably, an internal groove is also opened on the side of the tube box close to the tube sheet, and the shape of the internal groove is similar to that of the external groove.

[0009] Preferably, the internal shape of the internal groove is consistent with the external shape of the partition ribs, and the partition ribs and the internal groove are inserted and connected.

[0010] Preferably, the tube sheet is arranged in a disc-shaped structure, and a circular groove is provided at the connection between the tube sheet and the partition rib, and the partition rib is embedded in the groove of the tube sheet.

[0011] Preferably, a tube bundle is combined on one side of the tube sheet away from the partition rib, and the tube bundle is vertically distributed with respect to the tube sheet.

[0012] Preferably, the groove of the partition rib is consistent with the shape of one end of the tube sheet close to the partition rib, and one end of the tube sheet close to the partition rib is inserted and connected with the groove of the partition rib.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By adopting the novel connection structure between the tube sheet and the tube box under high-temperature working conditions, the spatial size of the cooler tube box is more compact. At the same time, the tube box and the tube sheet are connected by welding, greatly enhancing the sealing reliability. The partition ribs are pre-welded on the tube sheet, and corresponding internal grooves are processed at the partition rib positions in the internal tube box, separating the flow chambers from each other by the partition ribs. Groove partitions are processed between the inlets and outlets of the external tube box, minimizing the mutual heat conduction influence between the hot and cold sections at the tube box. The novel structure makes the external dimensions of the cooler more compact, with higher heat exchange efficiency and sealing reliability. BRIEF DESCRIPTION OF THE DRAWINGS

The arranged groove 101 can separate the high-temperature inlet 103 and the low-temperature outlet 102 of the tube box 1, reduce the heat conduction between the high-temperature inlet 103 and the low-temperature outlet 102, and make the equipment safer and more stable.

[0023] An internal groove 104 is also opened on the side of the tube box 1 close to the tube sheet 2, and the shape of the internal groove 104 is similar to that of the external groove 101.

A tube bundle 4 is combined on the side of the tube sheet 2 away from the partition rib 3, and the tube bundle 4 is vertically distributed with respect to the tube sheet 2, making the structure more compact. The groove of the partition rib 3 is consistent with the shape of one end of the tube sheet 2 close to the partition rib 3, and one end of the tube sheet 2 close to the partition rib 3 is inserted and connected with the groove of the partition rib 3, so that the tube sheet 2 can be more tightly connected to one end of the tube box 1, which is convenient for welding the connection between the tube box 1 and the tube sheet 2.

[0025] When the embodiment of the present application is in use: by opening an external groove 101 on the tube sheet 1, separating the low-temperature outlet 102 and the high-temperature inlet 103 on the tube sheet 1 through the external groove 101, reducing the heat conduction between the low-temperature outlet 102 and the high-temperature inlet 103, ensuring the compact structure and safety stability of the product. The internal groove 104 on one side of the tube sheet 1 close to the tube plate 2 will be inserted into the recessed partition rib 3 of the partition rib 3.
