Description
Technical field
The present invention relates to a kind of absorption heat pump and drive steam front-end system.
Background technology
Chinese patent disclose one " absorption-re-absorption-generation system and first-class absorption type heat pump " (notification number is:
CN 101957093A), its shortcoming is as follows: although whole system operationally can complete absorption-re-absorption generation system and first
The circulation of class absorption heat pump, but when starting in the early stage, absorption heat pump requires that driving steam is saturated vapor, and steam turbine carries
The steam of confession is superheated steam, it is therefore desirable to install attemperator on jet chimney, by the superheated steam temperature reduction before entrance heat pump
To saturation.In Practical Project, attemperator is with reference to nominal steam flow design, and in heat pump initial start stage, its institute
Need steam flow to be only nominal steam flow about 5%, which results in not mating of attemperator and steam flow.When input subtracts
During warm water, the desuperheating water of attemperator ejection is only vaporizated into steam on a small quantity and serves the effect reducing driving vapor (steam) temperature, absolutely
Major part desuperheating water cannot vaporize, and now, there is steam and water two media in jet chimney, at any time it may happen that steam pipe
Road water slug, is connected with steam turbine and heat exchangers for district heating due to heat pump steam main again, water slug once occurs, not only
Heat pump can be caused damage, also the safe and stable operation of steam turbine and heat exchangers for district heating can be threatened.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, easy to operate and heat pump can be made to open
The attemperator at dynamic initial stage drives steam front-end system with the absorption heat pump driving steam flow to match.
The present invention is achieved by the following technical solutions:
A kind of absorption heat pump drives steam front-end system, it include attemperator, absorption heat pump, steam adjusting valve door, seven sections
Drawing gas and heat pump body steam adjusting valve door, described attemperator pipeline at output is provided with two-way branch, and steam of leading up to is adjusted
Whole valve and seven sections of connections of drawing gas, heat pump body steam adjusting valve door of separately leading up to is connected with absorption heat pump.
Furtherly, described seven sections are drawn gas and are connected with condenser.
After using technique scheme, the positive effect of the present invention is as follows: the present invention drives jet chimney at heat pump
End installs one additional and starts steam adjusting valve door, then connects pipeline behind the door at startup steam adjusting valve and takes out to steam turbine seven sections
Vapour, installs simple, easy to operate, reliable;Absorption type heat pump system initial start stage, is on steam adjusting valve door, and increasing is driven
Dynamic steam flow makes it match with attemperator, reduces jet chimney generation water slug, also makes heat pump entrance drive simultaneously and steams
Stripping temperature is easy to control;Seven sections of extraction temperatures of steam turbine and heat pump drive vapor (steam) temperature close, can accomplish unnecessary driving
That moves steam thermal energy effectively utilizes maximization.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein, 1 attemperator, 2 absorption heat pumps, 3 steam adjusting valve doors, 4 seven sections draw gas, 5 heat pump body steam adjusting valves
Door, 6 condensers, 7 pipelines.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of absorption heat pump drives steam front-end system, including attemperator 1, absorption heat pump 2, steam
Adjust 3, seven sections of valve and draw gas 4 and heat pump body steam adjusting valve door 5;Described attemperator 1 pipeline at output 7 is provided with two-way and divides
, steam adjusting valve door 3 of leading up to draws gas with seven sections and 4 is connected, and separately leads up to heat pump body steam adjusting valve door 5 and absorption
Formula heat pump 2 connects.
In the present embodiment, drive steam flow less when absorption type heat pump system initial start stage absorption heat pump 2 is required
When being not enough to match with attemperator 1, open the steam adjusting valve door 3 installed additional, strengthen and drive steam flow to make itself and attemperator 1
Match, and unnecessary driving steam is caused steam turbine seven sections by pipeline 7 draw gas 4, heat by seven sections draw gas 4 condensation
Water, then drains into condenser 6;Along with the increase of heat pump body steam adjusting valve door 5 aperture, steam needed for absorption heat pump 2
When flow mates with attemperator phase 1, steam off adjusts valve 3.Present configuration is simple, easy to operate, can make absorption
The driving steam flow of heat pump 2 initial start stage matches with attemperator 1, effectively reduces the possibility of jet chimney generation water slug
Property, and unnecessary driving steam and heat thereof all obtained effective recycling.
The above embodiment is only the preferred embodiments of the present invention, and and the feasible enforcement of non-invention exhaustive.Right
For persons skilled in the art, to its done any showing on the premise of without departing substantially from the principle of the invention and spirit
The change being clear to, within all should being contemplated as falling with the claims of the present invention.
