Machine and method for cleaning evaporation tank

Abstract

The invention discloses a machine and a method for cleaning an evaporation tank. A frame of the machine is equipped with a central positioning shaft; two longitudinal tracks on the frame are equipped with sliding frames; transverse tracks on the sliding frames are equipped with water gun driving machines; the sliding frames and the water gun driving machines are all equipped with drive units; and the water gun driving machines are further equipped with clamping wheels for driving a water gun to move up and down. The method for cleaning the evaporation tank comprises the following steps: inserting the positioning shaft into a positioning seat hole at the center of an upper end plate of a shell-and-tube heat exchanger of the evaporation tank, and adjusting the distance from two ends of the longitudinal tracks to the inner wall of the evaporation tank to be smaller than 2.5cm; then starting a water pump of the water gun and the cleaning machine for the evaporation tank for spray-washing heat exchange tubes in a section of the shell-and-tube heat exchanger one by one, stopping the machine and moving the frame after the heat exchange tubes in the section are completely cleaned; and cleaning heat exchange tubes in next section one by one in the same way until tubes are completely cleaned. Compared with the prior art, the machine and the method provided by the invention have the advantages of high use safety and low labor intensity.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment manufacturing and cleaning operations for heat exchangers, in particular to a machine that controls high-pressure water guns to spray and clean heat exchange tubes of tube-and-tube heat exchangers, and uses this A method for cleaning heat exchange tubes of an evaporation tank by a machine. Background technique [0002] During the use of the heat exchanger, it is easy to form dirt in the heat exchange tube, which affects the heat exchange efficiency. The most typical heat exchanger is the heat exchanger in the evaporation tank of the sugar factory. The shell and tube heat exchanger in the evaporation tank has as many as 5,000 to 8,500 vertically arranged heat exchange tubes are prone to fouling on the inner wall of the heat exchange tubes during the evaporation process of the sugar solution, so that they have to be cleaned once a day. In the existing technical scheme, the cleaning equip...
