Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment, and in particular relates to a longitudinal distributed cooling water heat exchange equipment with high structural strength. Background Art

[0002] The cooling water generated by sintering waste in the steel industry has a high heat content. In order to efficiently utilize this part of the heat, the length of the shell and tube heat exchanger is made particularly large to improve the efficiency of waste heat recovery. However, this structure occupies a large area, and the cost of using a large-size shell and tube heat exchanger is relatively high. The longitudinally combined shell and tube heat exchanger is fixed by connecting bolts. When the upper shell and tube heat exchanger is subjected to external force and tilts forward and backward or left and right during use, the connecting bolts are subjected to a large shear force. When it is repaired, the connecting bolts are difficult to remove. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a longitudinal distributed cooling water heat exchange device which reduces the shear force of the connecting bolts of the two-layer shell and tube heat exchanger.

[0004] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: a longitudinal distributed cooling water heat exchange equipment with high structural strength, including a first shell and tube heat exchanger, a second shell and tube heat exchanger, a bracket, a first clamp, a second clamp, a third clamp, a first clamp, a second clamp and a reinforcing rod, the bracket is fixedly installed at the bottom of the first shell and tube heat exchanger, the first clamp is fixedly installed on the bracket by bolt locking, the second clamp and the third clamp are fixedly installed on the second shell and tube heat exchanger by bolt locking, and a positioning block is fixedly provided on the top of the first clamp. The top of the positioning block is provided with a positioning groove, and the bottom of the second clamp is fixedly provided with a positioning protrusion matching the positioning groove, and the positioning protrusion is slidably inserted in the positioning groove, the first clamp and the second clamp are arranged on the left and right sides of the third clamp and the bracket, and the first clamp and the second clamp are screwed and fixed by a first bolt and a lock nut, and the mounting ears of the bracket, the first clamp, the second clamp and the third clamp are provided with positioning holes matching the reinforcing rod, the reinforcing rod is slidably installed in the positioning hole, and the upper and lower ends of the reinforcing rod are respectively screwed and fixed to the third clamp and the bracket.

[0005] Preferably, the depth of the positioning groove at the top of the positioning block is set within 5-10 cm.

[0006] Preferably, the bottom edges of the positioning protrusions are all configured as bevel structures.

[0007] Preferably, the bottom bearing plate of the bracket is provided with bolt holes.

[0008] Compared with the prior art, the advantages of the utility model are as follows: the combined heat exchange equipment overcomes the requirements of a single large-size shell heat exchanger on the length of the site, and can make full use of the longitudinal space in the site. By arranging the first clamping plate, the second clamping plate and the reinforcing rod, the limiting force of the front and rear and left and right freedom of the first shell and tube heat exchanger and the second shell and tube heat exchanger can be strengthened, thereby reducing the shear force on the connecting bolts, extending the service life of the connecting bolts, and facilitating the disassembly of the connecting bolts during maintenance.
