Description

Technical Field

[0001] This utility model relates to a system for heating a refrigeration station using waste heat from a boiler. Background Technology

[0002] Because lithium bromide absorption chillers use water as a refrigerant and have an evaporation temperature above 0°C, they can only be used in air conditioning equipment and for preparing chilled water for production processes. These chillers can use low-pressure steam or hot water above 75°C as a heat source, and often use a special heater to heat the water. The waste heat of the condensate desuperheating water in power plants is not effectively utilized, and is simply allowed to cool naturally. At the same time, lithium bromide absorption chillers increase the consumption of electricity. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a system for heating a refrigeration station using waste heat from a boiler.

[0004] The above objectives are achieved through the following technical solutions: A system for heating a refrigeration station using waste heat from a boiler comprises a refrigeration station and a condenser. The water supply pipe of the waste heat boiler tail heater and the water supply pipe of the condensate desuperheating system converge at a heat source inlet pipe. The heat source inlet pipe is connected to the hot water inlet of the condenser. The hot water outlet of the condenser is connected to the heating water inlet of the refrigeration station through a heating water inlet pipe. The heating water outlet of the refrigeration station is connected to the return water pipe of the waste heat boiler tail heater through a heating water outlet pipe.

[0005] The system described above utilizes waste heat from a boiler to heat a refrigeration station, wherein a hot water booster pump is installed on the heating water outlet pipe.

[0006] The system described above utilizes waste heat from a boiler to heat a refrigeration station, wherein the refrigeration station is a lithium bromide refrigeration unit. Beneficial effects

[0007] 1. This utility model adopts two heat sources: one is the water supply from the tail heater of the waste heat boiler, and the other is from the condensate desuperheating water system. The water from the two heat sources enters the condenser and exchanges heat with the steam at the tail of the condenser before entering the refrigeration station. This allows the waste heat of the steam at the tail of the condenser to be utilized in two stages, while effectively utilizing the waste heat of the condensate desuperheating water, reducing power consumption and increasing the utilization rate of the waste heat of the condenser.

[0009] Reference Figure 1 A system for heating a refrigeration station using waste heat from a boiler comprises a refrigeration station 3 and a condenser 5. The water supply pipe 8 of the waste heat boiler tail heater and the water supply pipe 7 of the condensate desuperheating system converge at the heat source inlet pipe 6. The heat source inlet pipe is connected to the hot water inlet of the condenser. The hot water outlet of the condenser is connected to the heating water inlet of the refrigeration station through the heating water inlet pipe 4. The heating water outlet of the refrigeration station is connected to the return water pipe 9 of the waste heat boiler tail heater through the heating water outlet pipe 2.

[0010] A hot water booster pump 1 is installed on the heating water outlet pipe.

[0011] The refrigeration station is a lithium bromide refrigeration unit.

[0012] Two heat sources are used: one is the water supply to the tail heater of the waste heat boiler, and the other is the condensate desuperheating water system. The water from both heat sources enters the condenser and exchanges heat with the steam at the tail of the condenser before entering the refrigeration station. This allows for the secondary utilization of the waste heat from the steam at the tail of the condenser, while also effectively utilizing the waste heat from the condensate desuperheating water. This reduces energy consumption and increases the utilization rate of the condenser waste heat. The hot water entering the refrigeration station heats the lithium bromide solution, serving as the heat source for the lithium bromide solution in the refrigeration station. After heating, the solution is pressurized by a booster pump and returned to the return water pipe of the tail heater of the waste heat boiler.
