An evaporative absorber and its absorption refrigeration system

Abstract

The invention discloses an evaporative absorber in the technical field of absorption cycle, which comprises a synergistic device and several absorbers, the side wall of the synergistic device is connected with the absorber, and outer shells are installed on the outer sides of the plurality of absorbers , the bottom wall of the shell is connected with a water outlet, the water outlet is connected with a circulation pipe, and the circulation pipe is connected with a water inlet. The water inlet is installed on the side wall of the casing, and the circulation pipe is installed There is a circulating pump, and this device is used to replace the absorber and cooling tower in the existing absorption refrigeration system, which saves equipment, improves the integration of the device, and saves the indirect heat exchange of the original circulating water, which greatly reduces the circulation of circulating water. The required cycle power makes the lean solution flow from the top to the bottom under the action of gravity, while the gaseous refrigerant rises from the bottom to the top, combined with the corrugated side wall structure of the heat exchange device, slows down the flow rate of the lean solution and increases the absorption Over time, the absorption effect is improved.

Description

technical field [0001] The invention relates to the technical field of absorption cycle, in particular to an evaporative absorber and an absorption refrigeration system thereof. Background technique [0002] Waste heat refrigeration is a technology that uses the gas or waste gas, waste liquid in the production process, and the heat discharged by some power machinery as energy to drive compression or absorption refrigerators for refrigeration. Waste heat refrigeration can help us recover waste heat, save energy and reduce costs. [0003] Traditional compression refrigeration is a conversion process of electrical energy. The compressor sucks the low-pressure and low-temperature refrigerant gas (such as Freon) generated in the evaporator into the cylinder, and after being compressed, it becomes a gas with a higher pressure and temperature and is discharged into the condenser. It is condensed into a liquid, and then enters the evaporator through a pressure regulating valve to ...

Problems solved by technology

However, it is well known that there are generally cooling towers in the devices used with this system. When the cooling water in the traditional absorber is used, a circulation pump is required to drive the cycle, which will also cause a certain amount of power loss. When it is hot, cooling water is also required to take away the heat first, and then cool through the cooling tower. The heat exchange process is longer, which reduces the heat exchange efficiency.
