High-efficiency energy-saving modular chamber type heat exchanger

Abstract

The invention relates to a high-efficiency energy-saving module chamber heat exchanger, which comprises several heat exchangers while the inside tube cores are module structure and connected to the cylinder via flange; heat medium switches and coolant switches are arranged between heat exchangers to connect them. The invention utilizes module structure to apply maintenance, with high support ability, lower cost, long service life, less lose of pressure decrease, high section heating efficiency, better anti-heat property, and large capacity which is 1-3 times than others.

Description

Technical field: [0001] The invention relates to a heat exchanger, in particular to a high-efficiency energy-saving modular cavity heat exchanger. technical background: [0002] In the prior art, the existing shell-and-tube and plate heat exchangers have been found to have some disadvantages through long-term actual use conditions: [0003] The shell-and-tube heat exchanger connects the heat exchange tube with the tube sheet, and then fixes it with the shell; the stroke of the primary heat medium and the secondary heat medium are too short, and the utilization rate of the heat medium is only about 50%, which wastes a lot of energy. The use of heat increases the cost, and the process of shell and tube heat exchangers is relatively complicated, the maintenance cost is high, the equipment is not suitable for disassembly, and mineral ions are easy to crystallize, easy to block, easy to corrode and not durable. [0004] The plate heat exchanger is compose...

Problems solved by technology

[0003] The shell-and-tube heat exchanger connects the heat exchange tube with the tube sheet, and then fixes it with the shell; the stroke of the primary heat medium and the secondary heat medium are too short, and the utilization rate of the heat medium is only about 50%, which wastes a lot of energy. The use of heat increases the cost, and the process of shell and tube heat exchangers is relatively complicated, the maintenance cost is high, the equipment is not suitable for disassembly, and mineral ions are easy to crystallize, easy to block, easy to corrode and not durable

[0004] The plate heat exchanger is composed of plates, compression plates, rubber pads, brackets and other parts. Since the primary heat medium and the secondary heat medium of the plate heat exchanger are both single-stroke, and the stroke of the primary heat medium and the secondary heat medium is short. , the utilization rate of the heat medium is only about 50%, which wastes a lot of available heat, increases the cost, and causes thermal pollution to the surroundings; and the working pressure of the plate heat exchanger is ≤2MPa, and the working temperature is ≤200℃, which is not suitable for easy Blocking media, CL ion content in water should not be too high, rubber gasket seals are prone to leakage, limited by its structure and materials, and its service life is generally 2-3 years
