Evaporative absorber and absorption refrigeration system with same

Abstract

The invention discloses an evaporative absorber in the technical field of absorption cycle. The evaporative absorber comprises a synergy device and a plurality of absorber bodies, the side wall of thesynergy device is connected with the absorber bodies, the outer sides of the plurality of absorber bodies are provided with a shell, the bottom wall of the shell is connected with a water outlet in apenetrating manner, and the water outlet is connected with a circulating pipe in a penetrating manner; and the circulating pipe is connected with a water inlet in a penetrating manner, the water inlet is formed in the side wall of the shell, and a circulating pump is installed on the circulating pipe. An absorber and a cooling tower in an existing absorption type refrigeration system are replacedwith the evaporative absorber, equipment is saved, the integration degree of the evaporative absorber is improved, meanwhile, original circulating water indirect heat exchange is omitted, circulatingpower required by circulating water is greatly reduced, a barren solution flows from the upper portion to the lower portion under the action of gravity, gaseous refrigerants rise from the lower portion to the upper portion, and a corrugated side wall structure of a heat exchange device is combined, so that the downward flow speed of the barren solution is decreased, the absorption time is prolonged, and 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.
