Description
Technical field
The utility model relates to a kind of for heat exchange unit, particularly a kind of pump type heat gain of heat heat exchange unit to the Building group heat supply.
Background technology
In the northern area of China, heat supply in winter is an important people's livelihood problem that relates to huge numbers of families.Along with heat supply market is progressively withdrawed from inefficiency, with serious pollution "small and self-contained" coal heating station; Employing is with steam power plant's centralizedly supply loop high-temperature water, and distributed heat exchange station has become main flow to the pattern of Building group heat supply.Especially in large-and-medium size cities, the heat supply mode of this high-efficient energy-saving environment friendly that become basically universal.
In this heating system, steam power plant concentrates the loop high-temperature water (reaching as high as 130 ℃) of output to be called water one time, because the parameters such as the water quality of a water, pressure, temperature, flow are unwell to directly as the heating heat source water, therefore a water forms a close loop usually.
At this loop several distributed heat exchange stations are set and nearby Building group are heated respectively, the recirculated water of building direct heating is called intermediate water.
The heat transmission equipment of conventional distributed heat exchange station is the plate-type heat-exchange unit, has that construction investment is low, the simple advantage of operation maintenance, but has the poor chronic illness of heat capacity.
Cause that distributed heat exchange station (being heating plant) heat capacity deficiency mainly contains following three kinds of situations:
1. actual motion and design parameter are not inconsistent: show that the temperature of a water or flow do not reach designing requirement, thereby make the intermediate water temperature not reach requirement.
2. the waterpower of a grid system is unbalance.This situation can cause a discharge of indivedual heat exchange stations not up to standard, and the adjusting of the hydraulic equilibrium of pipe network system is very complicated problem, is difficult to thorough radical cure.
3. heating area dilatation.Newly-increased or newly-built building joins in the heating demand of heat exchange station, thereby makes the whole heat capacity of this heat exchange station not enough.In the process of urbanization fast development, this situation is also very common.
The temperature that increases the flow of a water or improve a water all can effectively solve above-mentioned three class problems, but actual conditions are all to be difficult to realize.Mean the pipe network system of transforming a water (can cause again new waterpower unbalance such as force (forcing) pump etc. is set, can not allow) because increase the flow of a water, and the pipe-line system of a water belongs to urban infrastructure, it is very big to transform difficulty.In line cities such as Beijing-Tianjins, it is almost unlikely to transform or set up a grid system; The temperature that improves a water also is subject to severely restricts, such as problems such as the heating power of the pressure-bearing of pipe network system and steam power plant are unbalance.Although therefore the problem of heat exchange station heat capacity deficiency is very common at northern area, be difficult for solving.Along with the quick propelling of urbanization, problem day by day highlights, and relates to the every aspects such as steam power plant, heating power operator, urban construction, residential block, become involve many areas, universal phenomenon that people's livelihood impact is large, need be effected a radical cure from the angle of technological innovation.
