It is characterized in that a gas-liquid heat exchanger (13) is arranged at the intermediate solution outlet of the high-temperature heat exchanger (2) and in which the intermediate solution goes to the low-voltage generator pipes (10) before going to the low-voltage generator (9). The high-voltage generator pipe (11) in which the gas and liquid from the high-voltage generator (1) is connected to the gas-liquid heat exchanger (13). The adoption of this method can decrease the gas temperature to below 120 Celsius system. As the extra gas recovery is part of the thermal energy, the unit fuel consumption can be reduced 3 to 5% so that the unit COP value increases 3 to 5%; consequently the unit operation costs are decreased. At the same time the thermal pollution caused by the gas emissions is also reduced.
Description
Technical field:
The utility model relates to a kind of lithium bromide absorption cold, hot water unit, particularly relates to a kind of lithium bromide absorption cold with the smoke solution heat exchanger, hot water unit.Belong to system, cold and hot equipment technical field.
Background technology:
Standard type direct combustion double-effect lithium bromide absorption type cold water in the past, hot and cold water unit (refer to the unit that thermals source such as fuel oil, combustion gas directly drive, down with) as shown in Figure 4, mainly constitute by high pressure generator 1, evaporimeter 5, absorber 4, low pressure generator 3, condenser 8, high-temperature heat exchanger 2, low temperature heat exchanger 3, solution pump 6, cryogenic fluid pump 7, control system and the pipeline that connects each parts.Provide thermal source by burner, because direct combustion double-effect lithium bromide absorption type cold water, hot and cold water unit is when operation, the flue gas in the high pressure generator with the solution heat exchange after, temperature is usually more than 180 ℃, technology in the past mostly is direct discharging greatly, causes the thermal loss of a part.How to make full use of this part waste heat, reduce the fuel consumption of unit, reduce thermal pollution, become the COP of lithium bromide absorption cold water, hot and cold water unit raising unit, an effective way of reduction fuel consumption.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of lithium bromide absorption cold, hot water unit that can make full use of the band smoke solution heat exchanger of the fume afterheat in the high pressure generator is provided.
The purpose of this utility model is achieved in that a kind of direct-burning type lithium bromide absorption type with the smoke solution heat exchanger is cold, the hot water unit, comprise high pressure generator, evaporimeter, absorber, low pressure generator, condenser, high-temperature heat exchanger, low temperature heat exchanger, solution pump, cryogenic fluid pump, control system and connect the pipeline of each parts, valve, it is characterized in that: the intermediate solution before the high-temperature heat exchanger intermediate solution exports and advances low pressure generator is advanced on the low pressure generator pipe, one smoke solution heat exchanger is set, and the flue gas that high pressure generator is come out goes out high pressure generator pipe access smoke solution heat exchanger.
The intermediate solution that the high-temperature flue gas heating high-temperature heat exchanger that utilizes high pressure generator to discharge exports enters low pressure generator after the heat of intermediate solution absorption high-temperature flue gas heats up, directly discharging behind the cooling high-temperature fume.Adopt this kind mode that the temperature of flue gas is reduced to below 120 ℃, reclaim this part heat of flue gas more, can reduce the fuel consumption 3～5% of unit, make the COP value of unit improve 3～5%, reduced the operating cost of unit.Simultaneously also reduce the thermal pollution that causes because of fume emission, met energy conservation and environment protection.In addition, because double-effect lithium bromide absorption type cold water, hot and cold water unit are when operation, pressure differential between high pressure generator and the low pressure generator is big, the ratio that the intermediate solution drag losses that increases by a smoke solution heat exchanger and increase accounts for is very little, so adopt original configuration, the not influence of flowing of intermediate solution.
