Abstract

The utility model relates to a high-efficiency, energy-conserving, diffusion-absorption refrigerating core, which is characterized in that the upper and lower holes are on the upper and the lower of the tube wall of the generator. The liquid-liquid interchanger pipe extents from the lower hole of the lower part of the generator and is welded with the lower part of the lift pipe, the upper part of which is welded with the upper hole in the upper part of the generator. The heater is positioned outside the lift pipe and has the liquid ammonia in the lift pipe directly heated, which enables the liquid ammonia in the life pipe to absorb quickly the heat from the heater and then vaporize. Meanwhile, the level of the liquid ammonia is fast lifted and then the high-purity ammonia gas is released by partly boiling away and condenses in a continous way. Ultimately, after the ammonia gas goes into the evaporator with the hydrogen simultaneously, the hydrogen declines by partial pressure and instantly produces the refrigerating capacity, and achieves the better refrigerating effect at last.

Description

High-efficiency and energy-saving type spread-absorbing type refrigerating core

Background technology

The utility model belongs to refrigeration machine, especially relates to a kind of spread-absorbing type refrigerating core.

Technical field

The spread-absorbing type refrigeration machine removes and adopts cold-producing medium, outside two kinds of working medium of absorbent, also charge into the inert gas auxiliary working substance, diffusion by inert gas, the liquefied ammonia dividing potential drop is reduced and evaporation is produced cold, refrigeration machine directly is motive force with the thermal source, utilize thermosiphon principle that working medium is circulated continuously, existing spread-absorbing type refrigerating core, its riser is installed in the inside of generator, heater is installed in the outside of generator, behind the tube wall and the solution in the pipe thereof that add heater earlier,, make the liquefied ammonia in the riser promote evaporation then by heat conduction indirect riser, so, beginning work is long heat time heating time, and calorific value consumption loss is higher, and refrigerating capacity is less under identical heating-up temperature.

Summary of the invention

The purpose of this utility model provides a kind of high-efficiency and energy-saving type spread-absorbing type refrigerating core, can quicken the liquefied ammonia in the heating riser, accelerates liquefied ammonia and promotes evaporation, thereby improve the liquefied ammonia amount of evaporimeter, accelerate kind of refrigeration cycle, increase refrigerating capacity, obtain better refrigeration.

The novel purpose of this practical fourth hand is achieved like this: a kind of high-efficiency and energy-saving type spread-absorbing type refrigerating core, by radiator, rectifier, evaporimeter, absorber, generator, riser, heater, liquid liquid exchange pipe, fluid reservoir, rare ammonia pipe, dense ammonia pipe and muffler, balance pipe is formed, it is characterized in that on the upper end section of the tube wall of generator and lower end section, opening hole and following hole respectively, to stretch out the following hole of liquid liquid exchange pipe on the section of generator lower end and weld mutually with following aperture, the external part welding of the lower port of riser and liquid liquid exchange pipe, the upper port of riser then with the generator upper end section on last hole weld mutually, heater is installed in the outside of riser, directly heat the liquefied ammonia in the riser, make liquefied ammonia in the riser absorb the heat of heater rapidly and vaporize, and make the liquid level fast lifting, by partly vaporization and condensation constantly, the ammonia that output purity is higher, behind condenser, enter evaporimeter simultaneously with hydrogen, make hydrogen branch drops and produce cold fast, obtain better refrigeration.

The high-efficiency and energy-saving type spread-absorbing type refrigerating core that the utility model proposed, it is simple in structure, and is safe and reliable, and start-up time is short, and the heating power consumption is little, and lifting capacity is big, and refrigerating capacity is big, long service life, good refrigeration effect.

Now the high-efficiency and energy-saving type spread-absorbing type refrigerating core of in conjunction with the accompanying drawings and embodiments the utility model being carried is further described.
