Abstract
Facilitate a shell-and-tube heat exchanger for cleaning in shell-side, be made up of end socket, cover flange, tube sheet, heat exchanger tube, housing, spray distance sink tube, deflection plate, blowdown nipple, bearing etc.; It is characterized in that: be designed with several blowdown nipple at housing bottom, replace the distance rod of current technology with spray distance sink tube; When needs washing and cleaning operation, pull down the blind plate of blowdown nipple, connect sewage pipe, dismounting end socket, backs out the plug of spray distance sink tube, connects high-pressure water pipe, can pass into water under high pressure and clean; Sewage after cleaning collects jetting machine through sewage pipe, processes Posterior circle after filtration and uses, to alleviate or to avoid the pollution to surrounding environment.The technical program overcomes the difficult problem that common shell heat exchanger shell pass is difficult to clean, for its service efficiency of raising, reduction clean and maintenance cost, increasing the service life has positive effect, and the technical program is applicable to various types of shell-and-tube heat exchangers such as stationary pipes shell-type, floating head type, U-shaped tubular type.
Description
Technical field
The present invention relates to a kind of heat exchanger, especially a kind of shell-and-tube heat exchanger facilitating cleaning in shell-side.
Background technology
Shell-and-tube heat exchanger, be the recuperative heat exchanger using closed wall of restraining in the housing as heat-transfer area, that commonly uses at present mainly contains fixed tube sheet type, floating head type and U-shaped tubular type three types.Because shell-and-tube heat exchanger can manufacture with various metal material, have firm in structure, operating flexibility is large, the degree of reliability is high, applied widely, can use under high temperature, condition of high voltage, therefore obtain extensive use in numerous industry such as oil, chemical industry, light industry, metallurgy, electric power.
It is exactly that the cleaning of heat exchanger shell side is very difficult that current shell-and-tube heat exchanger has in maximum shortcoming.For fixed tube-sheet exchanger, chemical immersion method can only be adopted to clean, for movable tube sheets heat exchanger or U-shaped pipe heat exchanger, also can adopt after loosing core and clean by high pressure water cleaning method.Be no matter adopt chemical immersion method or high pressure water cleaning method of loosing core to clean, all not only waste time and energy in the extreme, increase working service cost, and chemical immersion or loose core operation time, also easily damage heat exchanger body, the service life of shortening heat exchanger.
Summary of the invention
Object of the present invention: be can not solve the problems of the technologies described above for existing background technology, propose a kind of shell-and-tube heat exchanger facilitating cleaning in shell-side.
The present invention is achieved in that
Facilitate a shell-and-tube heat exchanger for cleaning in shell-side, be 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 is connected with case weld, exchanger tubes and tubesheets is welded to connect, spray spacing tube to tube sheet welding connects, deflection plate is connected with the spot welding of spray distance sink tube, and blowdown nipple is welded on housing bottom, and case weld is on bearing; It is characterized in that: be designed with several blowdown nipple at housing bottom, replace the distance rod of current technology with spray distance sink tube.
Above-described a kind of shell-and-tube heat exchanger facilitating cleaning in shell-side, is characterized in that: blowdown nipple is made up of short tube, flange and blind plate.
Above-described a kind of shell-and-tube heat exchanger facilitating cleaning in shell-side, it is characterized in that: spray distance sink tube is made up of shower and plug, spray tube to tube sheet welding connects, and the thread mated with plug third and high-pressure water pipe third joint is had at mouth of pipe place, shower tube wall is distributed with aciculiform spray apertures.
Above-described a kind of shell-and-tube heat exchanger facilitating cleaning in shell-side, is applicable to various types of shell-and-tube heat exchanger, as fixed tube-sheet exchanger or movable tube sheets heat exchanger or U-shaped pipe heat exchanger etc.
Advantage of the present invention:
