The utility model content
The purpose of the utility model is, a kind of heat supply network circulation is provided, the low-quality heat that it extracts from recirculated water; The heat recovery and utilization that recirculated water is taken away; For country saves the energy, reduce the pollution of environment simultaneously, improve heat pump mouth temperature and improve utilization rate of waste heat.
The technical scheme of the utility model: a kind of heat supply network circulation, comprise five sections steam extraction heads, heat supply network recirculated water feed pipe and heat pump, five sections steam extraction heads are connected with heat pump, between five sections steam extraction heads and heat pump, insert heat supply network recirculated water feed pipe.Because being provided with five sections steam extraction heads is connected with heat pump, utilize heat pump to absorb the low-quality heat in the recirculated water, be used, for country saves the energy, reduce the pollution of environment simultaneously.
In the aforesaid this heat supply network circulation, be provided with 4～11 heat pumps, be connected with five sections steam extraction heads after the heat pump parallel connection.
In the aforesaid this heat supply network circulation, be provided with 8 heat pumps.
In the aforesaid this heat supply network circulation, five sections extraction steam pipes are provided with heat exchangers for district heating.Owing to be provided with heat exchangers for district heating, guarantee that the heat pump outlet temperature satisfies the condition of heat supply network needs.
In the aforesaid this heat supply network circulation, heat exchangers for district heating is provided with circulation pump of heat-supply network.
In described this heat supply network circulation, heat pump adopts lithium bromide absorption type heat pump.Owing to be provided with lithium bromide absorption type heat pump, can reduce power consumption, reduce noise, make and operate steadily, its energy adjustment scope is wide, and environmentally safe.
Compared with prior art, be connected with heat pump, utilize heat pump to absorb the low-quality heat in the recirculated water, be used,, reduce the pollution of environment simultaneously for country saves the energy owing to be provided with five sections steam extraction heads.Owing to be provided with heat exchangers for district heating, guarantee that the heat pump outlet temperature satisfies the condition of heat supply network needs.Owing to be provided with lithium bromide absorption type heat pump, can reduce power consumption, reduce noise, make and operate steadily, its energy adjustment scope is wide, and environmentally safe.
