Abstract
The utility model discloses an absorption heat pump evaporimeter cryogen water circle device, include evaporimeter cryogen water tray, warning pipe, cryogen accumulator, frequency conversion cryrogenic fluid pump and cryogen storage water tank, evaporimeter cryogen water tray passes through the warning pipe to be connected with the cryogen accumulator, and the cryogen accumulator is through frequency conversion cryrogenic fluid pump and cryogen tank connection. The beneficial effects are that: owing to add and to be equipped with cryogen storage water tank and cryrogenic fluid pump, consequently can in time will unnecessaryly take out and loopback with cryogen water that lack, overcome in the actual motion the skew great and cryogen water overflow that appears and not enough of heat supply network return water temperature and design value.
Description
Technical field
The utility model relates to a kind of residual neat recovering system, and particularly a kind of water as refrigerant utilizing absorption heat pump to reclaim steam power plant's cooling circulating water extracts loop back device out.
Background technology
At present, utilize the cooling circulating water residual heat system of lithium bromide absorption type heat pump recovery power plant and other occasions various informative, relate to the various ways such as refrigeration, heating.More steam power plant relatively large is at present transformed into and utilizes power plant to bleed to drive lithium bromide heat pump to heat to absorb power plant's cooling circulating water waste heat, the heat pump supply and return water temperature of design is generally at 50/80 DEG C or 55/85 DEG C, but the off-design value that in actual motion, heat supply network return water temperature can be larger, and at In The Initial Period Of Heating, latter stage and freeze-up heat supply network return water temperature also can produce very big difference, therefore heat pump itself there will be water as refrigerant overflow phenomena, to this, equipment manufacturer generally understands random groups and is equipped with a set of refrigerant reservoir, be hung on outside unit, part cryogen overflow phenomena can be solved, but the overflow phenomena in all periods can not be solved.Particularly when preliminary heating period water as refrigerant needs to extract guarantee unit operation out normally, and freeze-up wishes supplementary water as refrigerant to adapt to now operating mode, so only can not meet above-mentioned requirements by refrigerant reservoir.
Summary of the invention
Technical problem to be solved in the utility model is, provides one to improve lithium bromide source pump water as refrigerant overflow phenomena, automatically realizes the extraction of the water as refrigerant after overflow, loop back device.
The technical scheme that the utility model adopts is: a kind of absorption heat pump evaporimeter water as refrigerant EGR, comprises, evaporimeter cryogen water pond, overflow pipe, refrigerant reservoir, frequency conversion cryogenic fluid pump and cryogen storage tank; Described evaporimeter cryogen water pond is connected with refrigerant reservoir by overflow pipe, and refrigerant reservoir is connected with cryogen storage tank by frequency conversion cryogenic fluid pump.
Described refrigerant reservoir is provided with liquid level gauge.
Described frequency conversion cryogenic fluid pump is arranged on pipeline.
Water as refrigerant that is unnecessary and that lack is extracted out and loopback by described cryogen storage tank and cryogenic fluid pump.
Described cryogen storage tank external application insulation material.
Described insulation material is styrofoam or rock wool.
The beneficial effects of the utility model are: owing to adding cryogen storage tank and cryogenic fluid pump, therefore in time water as refrigerant that is unnecessary and that lack can be extracted out and loopback, overcome heat supply network return water temperature and design load in actual motion and depart from the water as refrigerant overflow occurred and deficiency comparatively greatly.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of absorption heat pump evaporimeter of the utility model water as refrigerant EGR, comprises, evaporimeter cryogen water pond 1, overflow pipe 2, refrigerant reservoir 3, liquid level gauge, frequency conversion cryogenic fluid pump and cryogen storage tank 7; Described evaporimeter cryogen water pond 1 is connected with refrigerant reservoir 3 by overflow pipe 2, refrigerant reservoir 3 is provided with liquid level gauge, refrigerant reservoir 3 is connected with cryogen storage tank 7 by the frequency conversion cryogenic fluid pump be arranged on pipeline, generator 11 is connected with condenser 10 and solution heat exchanger 12 by pipeline, solution heat exchanger 12 is connected with solution pump 13 and absorber 9 by pipeline, and evaporimeter 1 is connected with condenser 10.
The operation principle of the utility model water as refrigerant EGR is: comprise and to take out outside heat pump self workflow, water as refrigerant and to recharge two parts.
Part I, first generator 11 is under the heating driving steam, inner bromize lithium dilute solution is evaporated, produces a large amount of refrigerant vapour, himself become concentrated solution through solution heat exchanger 12 with from the weak solution heat exchange of absorber 9 after enter in absorber 9 and spray.Absorb in absorber 9 and become weak solution after water as refrigerant steam, recycle; The refrigerant vapour produced in generator 11 then enters in condenser 10 and is condensed into liquid refrigerant water by the hot net water of heat exchange opposite side, enter in evaporimeter 1 after water as refrigerant decompression and carry out heat absorption and evaporate and absorb low-temperature circulating water waste heat, refrigerant vapour enters absorber through water fender afterwards.Heat supply network backwater enters condenser after entering in absorber the heat absorbed in absorber, completes secondary temperature elevation with after refrigerant vapour heat exchange.System completes whole kind of refrigeration cycle by the concentration difference in absorber and generator, and concentration difference increases, and water as refrigerant increases, otherwise water as refrigerant reduces.
Part II, at the heating initial stage, latter stage, or when in actual motion, heat supply network return water temperature is higher than design load, then liquid quality fraction raises, in solution, moisture reduces, in evaporimeter cryogen water pond 1, moisture increases, then may there is water as refrigerant overflow phenomena, the water as refrigerant now overflowed finally is stored in refrigerant reservoir 3 by overflow pipe 2, liquid level gauge 4 detects the water level in refrigerant reservoir 3, if water level reaches the upper limit, mean that refrigerant reservoir 3 volume is full, now should start cryogenic fluid pump 6, unnecessary water as refrigerant is introduced cryogen storage tank 7, cryogen storage tank 7 external application insulation material, avoid with extraneous heat exchange too much, affect unit performance, insulation material is styrofoam or rock wool.
At freeze-up, heating network return water temperature is on the low side, then liquid quality fraction reduces, in solution, moisture increases, in evaporimeter cryogen water pond 1, moisture reduces, then may there is cryogenic fluid pump emptying phenomenon, cause compressor emergency shutdown accident, now be stored in water as refrigerant in refrigerant reservoir 3 can automatic water-returning in evaporimeter, but the water yield stored due to this part is limited, when liquid level gauge 5 detect refrigerant reservoir 3 be in low water level time, now should start cryogenic fluid pump 8, unnecessary water as refrigerant is introduced in evaporimeter cryogen water pond 1 by cryogen storage tank 7, the system of guarantee has enough cryogens to be used for work.
