Description

Technical Field

[0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a high-efficiency heat exchanger for heat recovery. Background Art

[0002] The spray heat exchanger uses cooling water to spray directly on the outside of the tube to condense or cool the hot fluid in the tube, so it is generally called a spray heat exchanger. The cooling tubes of the spray heat exchanger are connected in sequence by U-shaped elbows and arranged up and down, and the number of rows of cooling tubes can be as many as 10-20 rows. A water spray device, such as a nozzle or a water tank, is installed on the top of the cooling tube, and the sprayed cooling water is sprinkled on the row of tubes by free fall.

[0003] Advantages of spray heat exchanger: Since the cooling water is directly sprayed on the outer wall of the pipe, some of the water will absorb the heat of the hot fluid in the pipe and evaporate. Spray heat exchanger is generally installed in the space where outdoor air circulates, and the air also absorbs some heat. Due to the joint cooling of cooling water and air, the heat transfer effect is good and the water consumption is small. Under the same conditions, the water consumption is almost half of that of the immersion heat exchanger. Although the spray heat exchanger consumes less water, it is not suitable for cooling petroleum products or organic gases that are prone to accidents if the water source is insufficient or the water supply is suddenly cut off.
