Description
Technical field
The utility model is related to the heat-exchanger rig of chemical field, more particularly to a kind of self-cleaning heat-exchanger rig.
Background technology
The heat-exchanger rig for being used in Chemical Manufacture industry at present is generally vertical or horizontal shell-and-tube heat exchanger, vertical shell-and-tube
The primary structure of heat exchanger includes housing, end socket, the heat exchanger tube located at enclosure interior, tube side feed tube, tube side drain pipe, shell side
Inlet, shell side liquid outlet and the blowoff valve located at lower housing portion；End socket is structure as a whole with housing；The left and right two of housing upper
Side-wall hole connects tube side feed tube and drain pipe respectively, and tube side liquid feed valve and tube side are respectively mounted on tube side feed liquor and drain pipe
Liquid valve；Shell side inlet is opened in lower housing portion side wall, and shell side liquid outlet is opened in housing upper side wall；When normally using,
Fluid enters heat exchanger tube pass by tube side feed tube, is flowed out by tube side drain pipe, and another heat exchanging fluid is entered by shell side
Liquid mouthful enters housing, is flowed out through shell side liquid outlet after heat exchange, reaches the purpose of cold fluid and hot fluid heat exchange.Due in actual production process
Needing the fluid of heat exchange has diversified forms, when the liquid of unholiness or easy crystallization flows through heat exchanger tube, just easily blocks heat exchanger tube,
Causing heat exchange efficiency reduces, it is impossible to meet production needs；Now need to take apart end socket using mechanical system cleaning, and due to end socket
It is integral type sealing structure with housing, causes dismounting difficult, cleaning efficiency is low, and mechanical chipping mode easily damages heat exchange
Pipe.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of self-cleaning heat-exchanger rig, by changing end socket and shell
The connected mode of body, the measure for setting up steam pipework and valve, realize the fast automatic cleaning of exchange heat pipe, are prevented effectively from heat exchange
The blocking of pipe, it is ensured that heat transfer effect.
To achieve the above object, the technical solution of the utility model is：
A kind of self-cleaning heat-exchanger rig, including housing, the heat exchanger tube located at enclosure interior, tube side feed tube, tube side go out liquid
Manage and located at the blowoff valve of lower housing portion；The left and right sides wall perforate of housing upper connects tube side feed tube respectively and tube side goes out liquid
Pipe, is respectively mounted tube side liquid feed valve and tube side liquid valve on tube side feed tube and tube side drain pipe；Its improvements is：It is also wrapped
Include the capping for being covered on case top, the steam pipe being connected with tube side feed tube, tube side drain pipe respectively.
A kind of above-mentioned self-cleaning heat-exchanger rig, the capping is connected with case top using flange；The steam pipe with
The connection end of tube side feed tube is located between tube side liquid feed valve and housing, and steam pipe is located at tube side with the connection end of tube side drain pipe
Between liquid valve and housing, steam valve is installed on steam pipe.
The utility model can exchange heat pipe and be cleaned automatically, and cleaning process is：It is first shut off tube side liquid feed valve and tube side
Liquid valve, stops to feed liquor in tube side, opens blowoff valve and steam valve, the upper chamber that high-pressure and high-temperature steam enters in housing,
And heat exchanger tube tube side is passed through from top to bottom, heat exchange inside pipe wall crystal is taken away using the impulsive force of high-temperature steam, eventually through row
Dirty valve discharge, cleaning can check heat exchanger tube inner wall washing situation after finishing by opening capping.
The beneficial effects of the utility model are：
The utility model realizes the fast and automatically cleaning of exchange heat pipe tube side using high temperature, high steam, and can be by tearing open
Lower capping carries out real time inspection to cleaning performance, and cleaning process will not exchange heat pipe and cause to damage, and effectively prevent heat exchanger tube
Block, it is ensured that heat transfer effect.
