Knock-out drum and heat exchanger

Abstract

The invention provides a knock-out drum and a heat exchanger, the knock-out drum comprises a knock-out plate and knock-out pipes, and the knock-out plate is provided with assembly holes; the knock-out pipe comprises a connecting section, an expansion section and a knock-out section which are connected in sequence, the outer diameter of the expansion section is larger than the diameter of the assembly hole, the connecting section is arranged in the assembly hole in a penetrating mode, and the expansion section is in limiting fit with one side of the knock-out plate; and the multiple knock-out pipes and the multiple assembling holes are arranged in a one-to-one correspondence mode. By the adoption of the scheme, due to the fact that the knock-out pipe comprises the connecting section, the expansion section and the knock-out section which are sequentially connected, after the connecting section penetrates into the assembly hole, the knock-out pipe can be axially limited through limiting cooperation of the expansion section and the knock-out plate, and the knock-out pipes are installed on the knock-out plate. The knock-out drum can be manufactured by adopting the connecting mode instead of a welding mode, so that welding deformation of the knock-out drum is avoided, and the rate of finished products and the machining precision of products are improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a liquid separator and a heat exchanger. Background technique [0002] The liquid separation of the shell and tube heat exchanger at the inlet of the heat exchange tube bundle has a great influence on the performance of the heat exchanger and the stability of the unit operation. Due to the large number of tube bundles, the distribution of the inlets of the heat exchange tubes often cannot be arranged in a regular manner in the structure, resulting in the difficulty of liquid separation at the inlets of each heat exchange tube. In order to solve the problem of uniform liquid separation, some heat exchangers are equipped with liquid separators for liquid separation. [0003] The liquid separator usually includes a liquid separation plate and a plurality of liquid separation pipes. In the prior art, a brazing process is usually used to weld a plurality of liquid separation ...

AI Technical Summary

Problems solved by technology

[0003] The liquid separator usually includes a liquid separation plate and a plurality of liquid separation pipes. In the prior art, a plurality of liquid separation pipes are usually welded on the liquid separation plate by a brazing process. The tube and liquid separator plate are prone to damage and deformation, so it is difficult to guarantee the quality and precision of the finished product, the processing technology is difficult, and the yield is low

Moreover, after the distributor is deformed, it is not easy to assemble with structures such as heat exchange tubes.

Generally, the smaller the diameter of the liquid pipe, the more difficult it is to weld, so the brazing process also restricts the size and use effect of the liquid pipe
