An ultrasonic cleaning device for heat exchanger cooling tube

Abstract

A heat exchanger cooling pipe ultrasonic cleaning device comprises a probe, a rotary sprayer, a front cover plate and a rear cover plate. The probe, the rotary sprayer, the front cover plate and the rear cover plate are connected through a connecting pipe. A sealed cylinder is connected between the front cover plate and the rear cover plate. The front end of the sealed cylinder is connected to the front cover plate, and the rear end of the sealed cylinder is connected to the rear cover plate. Multiple piezoelectric ceramic rings and multiple electrode plates are arranged on the portion, between the front cover plate and the rear cover plate, of the connecting pipe in a sequentially overlapped mode. Each electrode plate is connected with an ultrasonic power source through a wire. The rear end of the rear cover plate is connected with a water pipe. The rear cover plate is provided with a through hole. A glaze section of the connecting pipe is provided with one or more radial holes in the radial direction. The rotary sprayer is provided with one or more spray holes. A liquid storage cavity is formed in the probe. The probe is provided with one or more probe spray holes. The device is small, easy to operate, high in efficiency, capable of cleaning multiple cooling pipes at the same time, safe, environmentally friendly and low in power consumption; no chemical needs to be added, and energy and electricity are saved; the device is used for thoroughly cleaning scale on the inner walls of the cooling pipes of a heat exchanger, and meanwhile scale on the outer walls of the cooling pipes can also be cleared up.

Description

technical field [0001] The invention relates to an ultrasonic cleaning device, in particular to an ultrasonic cleaning device for a cooling pipe of a heat exchanger. Background technique [0002] There are a large number of cooling pipes distributed in the heat exchanger. The cooling pipes are made of copper or other materials with good heat transfer effects. Generally, the circulating water passes through the cooling pipes, and the heat exchange materials are outside the pipes. The cooling pipes are used to realize the exchange between the two materials. During the heat exchange process, the inner wall of the cooling tube is prone to fouling, which reduces the heat exchange effect and creates potential safety hazards. In severe cases, it may lead to accidents such as pipe bursts and shutdowns. [0003] After the cooling pipe is fouled, high-pressure water gun flushing and chemical pickling are generally used at present. [0004] The main disadvantages of high-pressure wate...
