The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
Embodiment
A kind of lithium bromide chiller combustion adjustment method based on combustion gas distributed busbar protection, combustion gas distributed busbar protection includes
Internal combustion engine, the equipment such as lithium bromide chiller, lithium bromide chiller is fume hot-water type dual effect absorption lithium bromide chiller.Combustion adjustment
Method is related to flue gas triple valve 1,3 three parts of flue gas high pressure generator 2 and hot water heat exchanger, three of flue gas triple valve 1
Branch road is connected with internal combustion engine exhanst gas outlet, the entrance of flue gas high pressure generator 2 of lithium bromide chiller and surrounding air respectively, and flue gas is high
Pressure generator 2 is a part in lithium bromide chiller, is the part that flue gas exchanges heat with lithium bromide refrigerating agent, the bromine in this part
Change the lithium bromide steam that lithium solution is evaporated to HTHP, and condenser 4, hot water heat exchange are arrived later by hot water heat exchanger 3
Device 3 is a part in lithium bromide chiller, is heat medium water and the vapor heated part of lithium bromide, and condenser 4 is lithium bromide machine
A part in group, is cooling water and the vapor heated part of lithium bromide.
General lithium bromide chiller needs the switching of valve to carry out the conversion of refrigeration and heating mode.Lithium bromide refrigerating band system
The measure of heat refers to that relatively low in conditioning in Transition Season refrigeration duty, in the case that flue gas can not dissolve completely, lithium bromide chiller is in refrigeration mode
Under, heated while opening hot water side.
Because flue gas threeway valve opening and chilled water return water temperature are linear, and can be with hand on unit operation interface
It is dynamic to set the linear relationship equation.Such as lithium bromide chiller is under mark condition, and supply and return water temperature is 6/15.6 DEG C, now flue gas three
Port valve aperture and the linear relationship of return water temperature are as shown in a lines in Fig. 1.But in conditioning in Transition Season, return water temperature reduction, is 12 DEG C,
In order that flue gas triple valve keeps standard-sized sheet under relatively low chilled water return water temperature, the line of flue gas triple valve and return water temperature is set
Sexual intercourse is as shown in b lines in Fig. 1.
When return water temperature is reduced lithium bromide in cooling mode, there is the situation that flue gas excessively causes waste heat to waste, note
The now pressure occurred frequently of lithium bromide under record.Then it is 100% to manually set flue gas threeway valve opening under the return water temperature, works as flue gas
During triple valve standard-sized sheet, the pressure of smoke generator can be made to increase due to the increase of condensed steam, now, if by a certain amount of
Hot water enters hot water heat exchanger, is exchanged heat with condensed steam, can make the pressure of smoke generator reduces, until the height of lithium bromide chiller
Hair pressure reaches original pressure occurred frequently recorded when only freezing.
Certain Distribution of Natural formula energy source station co-feeding system generating equipment uses Jenbacher J624 internal combustion engines, and its rated power is
4.4MW.Utilizing waste heat for refrigeration equipment uses fume hot-water type lithium bromide chiller, and the specified out temperature of its chilled water is 15.6/6.0
DEG C, metered flow is 380t/s, and the specified out temperature of heat medium water is 90/65.5 DEG C, and metered flow is 150t/s.Cooling-water machine is made
For cooling peak regulation equipment, its electricity refrigeration supply water temperature is 5.5 DEG C, and metered flow is 300t/s.Hot-water boiler is used as Heating Adjustment
Equipment, rated power is 7.0MW, and it is 90/65.5 DEG C to import and export water temperature, and metered flow is 150t/s.Controlled by collection analysis DCS
After system data processed, in conditioning in Transition Season, internal combustion engine actual motion power is 4.0MW.The actual chilled water of lithium bromide chiller supplies backwater temperature
Spend for 6.7/9 DEG C, the actual supply and return water temperature of heat medium water is 90/82 DEG C.Cooling-water machine supply water temperature is constant.Hot-water boiler is actual to be supplied back
Coolant-temperature gage is 90/82 DEG C, and actual flow is 400t/h or so.
Under cooling condition, to keep lithium bromide chiller to run at standard conditions, it is necessary to assure return water temperature is
15.6℃.As shown in Fig. 2 because conditioning in Transition Season customer charge is small, when chilled water return water temperature is relatively low, now flue gas triple valve 1
It is not full of, records the pressure occurred frequently of lithium bromide under the return water temperature, remaining parameter can changes with the change of pressure occurred frequently, because
This need not be recorded.Then the linear relationship equation of the aperture of flue gas triple valve 1 and return water temperature is manually set, makes the backwater temperature
The lower standard-sized sheet of flue gas triple valve 1 of degree.When flue gas 1 standard-sized sheet of triple valve, occur due to the increase of condensed steam flue gas high pressure
The pressure of device 2 rises, now, and unlatching heats side valve door, enters hot water heat exchanger 3 by a certain amount of hot water, with condensed steam
Heat exchange, can make the pressure of flue gas high pressure generator 2 reduces, when the pressure occurred frequently of lithium bromide chiller reaches original only refrigeration
Pressure occurred frequently.
With certain on October 19,8：Exemplified by 30 experimental datas, while cooling and warming, lithium cold water entrance temperature is
11.1/5.4 DEG C, flow is 559.8t/h, and hot water entrance's temperature is 79.7/87.7 DEG C, and flow is 78.7t/h.Natural gas is used
Measure as 975Nm3, engine load is 3995kW.Therefore, primary energy ratio can reach 89.8%.As can be seen here, lithium bromide
Cooling and warming can significantly increase the utilization rate of waste heat of lithium bromide simultaneously, reduce loss.
In order to preferably find the equalization point of lithium bromide, it can be appreciated that it is following some：
1st, lithium bromide heat medium water outlet regulating door aperture is certain, makes the heating agent water-carrying capacity passed through certain (because heat medium water is returned
Coolant-temperature gage compares flue-gas temperature in flue gas heat-exchange unit and differs larger, therefore does not consider the decline for the pressure occurred frequently that the temperature difference is caused), so
Just it can determine that a certain amount of heat medium water is crossed pressure occurred frequently produced after lithium bromide and declined.
2nd, under each chilled water return water temperature of observed and recorded, the pressure occurred frequently (flue gas three during heat medium water spare gate is not opened
Port valve is not in fully open position).
3rd, flue gas threeway valve opening is manually adjusted, it is high when making lithium bromide in cooling mode by a certain amount of heat medium water
Hair pressure can also keep not open pressure during heat medium water spare gate.
4th, control internal combustion engine meets in 4000kw or so, reduces exhaust gas volumn and changes brought influence.
