Abstract
A shell-and-tube heat exchanger capable of conveniently cleaning a shell pass is composed of an end socket, an end socket flange, a tube sheet, a heat exchange tube, a shell, a spraying pipe spacer, a baffle plate, pollution discharge nipples, a support and the like. The shell-and-tube heat exchanger capable of conveniently cleaning the shell pass is characterized in that a plurality of pollution discharge nipples are designed at the bottom of the shell, and a spaced rod in an existing technology is replaced by the spraying pipe spacer. When a cleaning operation is needed, blind plates of the pollution discharge nipples are dismounted, pollution discharge water pipes are connected, the end socket is dismounted, an end cap of the spraying pipe spacer is screwed off, a high-pressure water pipe is connected, and cleaning can be carried out by filling high-pressure water. Sewage after being cleaned is collected into a high-pressure cleaning machine through the pollution discharge water pipes, the sewage is recycled after filtration treatment to reduce or avoid the pollution on surroundings. According to the shell-and-tube heat exchanger capable of conveniently cleaning the shell pass, the problem that a shell pass of a common shell-and-tube heat exchanger is cleaned difficultly is solved, the shell-and-tube heat exchanger capable of conveniently cleaning the shell pass has positive significance that use efficiency of the shell-and-tube heat exchanger is improved, washing and maintaining cost are reduced, and the service life is prolonged. According to the technical scheme, the shell-and-tube heat exchanger capable of conveniently cleaning the shell pass is suitable for fixing various shell-and-tube heat exchangers which are of a shell-and-tube type, a floating-head type, a U-shaped-tube type and the like.
Description
Technical field
The present invention relates to a kind of heat exchanger, especially a kind of shell-and-tube heat exchanger that makes things convenient for shell side to clean.
Background technology
Shell-and-tube heat exchanger is to be enclosed in the wall of restraining in the housing as the recuperative heat exchanger of heat-transfer area, at present three types of fixed tube sheet type, floating head type and the U-shaped tubular types that mainly contain commonly used.Because shell-and-tube heat exchanger can be with various metal material manufacturings, have firm in structurely, operating flexibility is big, degree of reliability height, applied widely, can under high temperature, condition of high voltage, use, therefore obtain extensive use in numerous industries such as oil, chemical industry, light industry, metallurgy, electric power.
At present the shortcoming in maximum is arranged is exactly that the cleaning of heat exchanging device shell side is very difficult to shell-and-tube heat exchanger.For fixed tube-sheet exchanger, can only adopt the chemical immersion method to clean, for movable tube sheets heat exchanger or U-shaped pipe heat exchanger, also can adopt the back of loosing core to clean with the water under high pressure ablution.No matter be to adopt chemical immersion method or the water under high pressure ablution of loosing core to clean, all not only waste time and energy, increase the working service cost in the extreme, and at chemical immersion or when loosing core operation, damage heat exchanger body easily also, the service life of shortening heat exchanger.
Summary of the invention
Purpose of the present invention: be to solve the problems of the technologies described above at existing background technology, proposed a kind of shell-and-tube heat exchanger that makes things convenient for shell side to clean.
The present invention is achieved in that
A kind of shell-and-tube heat exchanger that makes things convenient for shell side to clean is made up of end socket, tube side dividing plate, cover flange, tube sheet, heat exchanger tube, housing, spray distance sink tube, deflection plate, blowdown nipple, bearing etc.; End socket and cover flange are welded to connect, tube side dividing plate and end socket are welded to connect, cover flange is connected by nut bolt with tube sheet, tube sheet and housing are welded to connect, heat exchanger tube and tube sheet are welded to connect, spray distance sink tube and tube sheet are welded to connect, deflection plate is connected with the spot welding of spray distance sink tube, and the blowdown nipple is welded on housing bottom, and housing is welded on the bearing; It is characterized in that: in the housing bottom design several blowdown nipples are arranged, replace the spacing bar of present technology with the spray distance sink tube.
Above-described a kind of shell-and-tube heat exchanger that makes things convenient for shell side to clean, it is characterized in that: the blowdown nipple is made up of short tube, flange and blind plate.
Above-described a kind of shell-and-tube heat exchanger that makes things convenient for shell side to clean, it is characterized in that: the spray distance sink tube is made up of shower and plug, shower and tube sheet are welded to connect, and have the thread that mates with plug third and high-pressure water pipe third joint at mouth of pipe place, be distributed with the aciculiform spray apertures at the shower tube wall.
Above-described a kind of shell-and-tube heat exchanger that makes things convenient for shell side to clean is applicable to various types of shell-and-tube heat exchangers, as fixed tube-sheet exchanger or movable tube sheets heat exchanger or U-shaped pipe heat exchanger etc.
Advantage of the present invention:
Above-described a kind of shell-and-tube heat exchanger that makes things convenient for shell side to clean can overcome the difficult problem that common tube shell heat exchanger shell side is difficult to clean, thereby reaches the service efficiency that improves heat exchanger, the purpose that reduces the clean and maintenance cost, increases the service life.
