Description
Technical field
The utility model 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, form the tube side where low-temperature receiver, outside is the housing where heat source, and heat source dissipates in housing
Heat loss is big, heat exchange efficiency is low, takes up a large area.During for condenser or heat exchangers for district heating, steam is in housing by putting
Hot natural condensation is converted into condensation water, and condensing water temperature is high, pressure is low, it is necessary to install steam trap and condensation hydroecium additional, it could just
Often work, and do not allow easy to be recycled, it is necessary to have special condensate pump and condensate tank, it can just be worked normally, mating
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 be easy to cause, after working long hours
Heat exchange blockage is be easy to cause, resistance increases, and circulation pump power is caused 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 equipment damage, causes the pressure rise of pipeline,
Cause the danger such as booster, explosion, service life is short, general 4~6 years, and maintenance cost is high, and repair, clean it is extremely inconvenient.
Existing plate heat exchanger, it carries out multi-disc combination by the stainless steel plate of mould punching by multi-disc, passes through
Bolt or the form of welding are attached.The left and right sides of every plate forms independent passage, then by gasket, company
Interface etc. forms a heat exchanger.Because plate passes through the punching press of mold, plate is stretched and thinned, be easy to cause partial points corruption
Erosion；Runner simultaneously between plate and plate is more narrow and small, the degree of purification for running medium is required high, 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
Abrasion is caused to wash away, the service life for causing equipment is 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 influenced by structure type, repair cleaning is extremely not
Just, the workload of single repair cleaning is very big；Because the stress that mechanical processing is caused in punching course can not discharge, cause equipment
Stress corrosion often occurs, plate cannot repair, and can only disposably scrap, and cause service life short (general 3~5 years), energy
Source largely wastes, and does not meet energy saving, emission reduction state basic policy.
