Utility model content
The purpose of this utility model is to provide a kind of easy to clean, heat exchange efficiency is high, and efficiently solves the spiral tube-row heat exchanger of oilfield sewage etching problem in pipe row.
The technical scheme that realizes above-mentioned purpose is: spiral tube-row heat exchanger, the cylindrical shell that comprises sealing, the upper and lower end two ends of cylindrical shell are connected with respectively end socket, it is characterized in that: the center in described cylindrical shell is provided with vertical intermediate cylinder, the two ends up and down of intermediate cylinder are tightly connected with cylindrical shell respectively, described intermediate cylinder is arranged with spiral tube-row outward, described spiral tube-row comprise many from inside to outside successively nested helix tube form, the inwall of every helix tube is provided with anticorrosive coat, and the two ends up and down of every helix tube are as the import and export of high-temperature medium; Cryogenic media import and export and high-temperature medium import and export are set on cylindrical shell, cryogenic media import and export is communicated with cylinder lumen respectively, the entrance end of spiral tube-row is serially connected between high-temperature medium import and export, and high-temperature medium import and export is tightly connected with spiral tube-row entrance end respectively.
Above-mentioned cryogenic media import is arranged on cylindrical shell bottom one side, and cryogenic media outlet is arranged on the opposite side on cylindrical shell top; High-temperature medium import is arranged on the upper end of cylindrical shell, and high-temperature medium import is connected with the upper port of spiral tube-row, and high-temperature medium outlet is arranged on the lower end of cylindrical shell, and high-temperature medium outlet is connected with the lower port of spiral tube-row.
The two ends up and down of above-mentioned spiral tube-row are imported and exported and are connected with high-temperature medium by manifold respectively, described manifold is the bullet of hollow, the osculum end of bullet is liquid outlet, on the big opening end of bullet, be provided with the manhole corresponding with helix tube quantity, the entrance point of many helix tubes of spiral tube-row and the port of export are tightly connected by bend pipe with the manhole of the big opening end of the manifold of corresponding side is corresponding one by one respectively.
The beneficial effects of the utility model:
The utility model, in conjunction with the advantage of coil heat exchanger and votator, is used and tubulation row spiral, reaches the effect that increases heat exchange area in certain space; Helical flow path can change fluidised form, forms turbulent flow, solves fouling and blockage problem; In pipe row, walk oilfield sewage, and in be covered with anticorrosive coat, reach the object of anti-corrosion anti-scale; Caliber wants large than movable tube sheets heat exchanger, is beneficial to waterpower and cleans.Main effect is as follows:
1, successful Application in field produces sewage remaining energy recovery system, under same heat exchange area, its volume reduces greatly, and heat transfer rate obviously promotes than movable tube sheets heat exchanger;
2, the heat-transfer surface fouling cycle obviously extends;
3, easy to clean, cleaning performance is good;
4, in pipe row, there is anticorrosive coat effectively to solve oilfield sewage etching problem;
5, good airproof performance, has eliminated the working media possibility of string mutually substantially.
