Description
Technical field
The present invention relates to a kind of heat-exchanger rig, belong to energy technology field.
Background technology
Containing abundant low grade heat energy in the non-clean water such as sewage, surface water, utilize heat pump techniques these low grade heat energies can be extracted into building heating air-conditioner, have huge energy-saving and environmental protection and economic worth, its energy-conservation amplitude can reach more than 45%.By the existing quantity of wastewater effluent measuring and calculating of China, develop sewage Lowlevel thermal energy (by temperature drop 4 ~ 5 DEG C calculating), can be the City Building heat supplying air conditioning of 20%, its development prospect is boundless, is one of effective way of building energy conservation reduction of discharging.
Source of sewage or earth surface water source are all the one at water source, and comparing its main feature of underground water is that impurity content is large, easily forms dirt at heat exchange wall, not only affect heat exchange efficiency, increase the flow resistance of fluid, also can accelerate wall erosion, heat transmission equipment is reduced service life greatly.Therefore, antiscale, scale removal are the key technologies utilizing non-clean water to carry out heat exchange.
Current anti-descalling technique mainly contains following two kinds of forms, and all there is certain deficiency.
One is glueballs on-line cleaning technology, as the patent No. 201320209861.1, notification number CN203240955U, name are called the utility model patent of " ball cleaning apparatus for heat pump ", it be by glueballs in flow process with the rubbing action of heat exchanger tube inwall, reach and carry out the object of cleaning with glueballs heat exchanging inside pipe wall, but its result of use when water quality is poor is undesirable, not only ball collecting rate is low, and secondary filter and ball screen exist the problem of fouling and corrosion equally, heat exchange efficiency is low.
Two is insert in pipe (as rotated tie etc.) on-line cleaning technology, as the patent No. 200720154258.2, notification number CN201034457Y, name are called the utility model patent technology of " Automatic descaling enhanced heat exchanger of helical coils ", it relies on the effect of fluid to rotate or vibrates the object reaching anti-scale removal, but it is large for heat exchange area, heat-transfer pipe quantity is many and long non-clean water-to-water heat exchanger, its mechanical technology is too complicated, initial cost is large, and the many non-clean water of impurity content is easy to blocking, the corrosion and damage of cause insert, affects heat exchange efficiency.
Summary of the invention
