Description
Technical field
The invention belongs to heat exchange equipment technology, and in particular to a kind of heat exchanger.
Background technology
Existing corrugated tube heat exchanger, tubular heat exchanger are forced turbulent heat exchanger, it by two tube sheets it
Between fix more straight-through heat exchanger tubes, the tube side formed where low-temperature receiver, outside is the housing where thermal source, and thermal source dissipates in housing
Heat loss is big, heat exchange efficiency is low, floor space is big.During for condenser or heat exchangers for district heating, steam is in housing by putting
Hot natural condensation, condensate is converted into, condensing water temperature is high, pressure is low, it is necessary to install steam trap additional and condense hydroecium, it could just
Often work, and does not allow easy to be recycled, it is necessary to have special condensate pump and condensate tank, it just can normal work, it is supporting
Equipment investment is big, and installation is extremely inconvenient；The coefficient of heat transfer (K values) is very low, and vapour-water heat exchange heat transfer coefficient (K values) is 2000-
3000W/(m2.k)；In addition, low-temperature receiver water quality is generally poor, in Bottomhole pressure, heat exchanger tube fouling is easily caused, after working long hours
Heat exchange blockage is easily caused, resistance increases, and causes circulation pump power to increase, and wastes electric power, also, the coefficient of heat transfer drops significantly
It is low, the energy is wasted, increases coal consumption and power consumption, when fouling is serious, or even makes device damage, causes the pressure rise of pipeline,
Cause the danger such as booster, blast, service life is short, general 4~6 years, and maintenance cost is high, and repair, clean it is extremely inconvenient.
Existing plate type heat exchanger, it carries out multi-disc combination by the stainless steel plate of mould punching by multi-disc, passed through
Bolt or the form of welding are attached.The left and right sides of every plate forms independent passage, then by sealing gasket, company
Interface etc. forms a heat exchanger.Because plate passes through the punching press of mould, plate is stretched and thinned, easily causes partial points corruption
Erosion；Runner simultaneously between plate and plate is more narrow and small, requires high to the degree of purification for running medium, it is easy to cause to block up
Plug；Because runner is more narrow and small, the flow velocity between plate is higher (2.5~4.5m/s), therefore the resistance of equipment is larger, and easily
Cause abrasion to wash away, cause the service life of equipment shorter.Although higher (2000~the 4000W/ of the liquid-liquid coefficient of heat transfer
(m2.k)), but when vapour-liquid exchanges heat, basically can not use.In addition, being influenceed by structure type, maintenance cleaning is extremely not
Just, the workload of single maintenance cleaning is very big；Because the stress that machining is caused in punching course can not discharge, cause equipment
Stress corrosion often occurs, plate can not repair, and can only disposably scrap, and cause service life short (general 3~5 years), energy
Source largely wastes, and does not meet energy-conservation, the state basic policy of emission reduction.
