Ultrasonic spiral flat tube heat exchanger

Abstract

The invention discloses an ultrasonic spiral flat tube heat exchanger. The ultrasonic spiral flat tube heat exchanger comprises a left end face end socket, a left tube plate, a heat exchanger shell, a right tube plate and a right end face end socket which are connected in sequence. Spiral flat tubes are horizontally arranged in the heat exchanger shell. A baffling baffle is horizontally arranged in the left end face end socket. A first ultrasonic generation device is horizontally arranged on the upper portion of the baffling baffle and fixed to the side wall of the left end face end socket. One end of the first ultrasonic generation device is located outside the left end face end socket, and the other end of the first ultrasonic generation device is located in the left end face end socket. A second ultrasonic generation device is horizontally arranged on the lower right portion of the right end face end socket. One end of the second ultrasonic generation device is located outside the right end face end socket, and the other end of the second ultrasonic generation device is located in the right end face end socket. According to the ultrasonic spiral flat tube heat exchanger, scaling in the tube walls can be prevented, coking and blockage in the tube walls are avoided, the equipment maintenance period is prolonged, and the ultrasonic spiral flat tube heat exchanger is suitable for the technical field of industrial heat exchange.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to an ultrasonic spiral flat tube heat exchanger. Background technique [0002] Scaling and coking of shell-and-tube heat exchange equipment have always been a major problem in the field of heat exchange, especially in the development of offshore oilfields. Scaling and coking of crude oil heat exchangers will greatly reduce heat exchange efficiency and cause dehydration of crude oil. The temperature is low and difficult to handle. The heat exchanger has a short service life and needs to be cleaned frequently, and the traditional mechanical cleaning and chemical cleaning methods require disassembly of the equipment, which is troublesome to operate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an ultrasonic spiral flat tube heat exchanger, which can prevent fouling in the tube wall, avoid coking and blockage ...
