Description

The generating means of residual heat type ammonia water absorbing refrigerator

Technical field

The utility model relates to a kind of generating means of refrigeration machine, particularly a kind of generating means of residual heat type ammonia water absorbing refrigerator.

Background technology

At present, existing ammonia absorption type refrigeration agent mainly comprises transmitter, segregator, condenser, evaporimeter, absorber and solution heat exchanger, in order to obtain the ammonia steam of high concentration, improves the efficient of refrigeration machine, between generator and segregator, also be provided with rectifier, the structure of rectifier is comparatively complicated, and generating means mainly relies on combustion gas, and fuel oil is as thermal source, although saving electric energy, but still use the disposable energy, and refrigerating efficiency is relatively low, the making a low multiple use of the energy.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model just is to provide, and manufacturing cost is lower, and heat utilization efficiency is high, can improve the generating means of the residual heat type ammonia water absorbing refrigerator of heat exchange efficiency and complete machine thermodynamic coefficient.

To achieve these goals, the technical solution adopted in the utility model is such: the generating means of residual heat type ammonia water absorbing refrigerator of the present utility model, comprise shell, the relative two sides of shell are provided with smoke inlet and exhanst gas outlet, be provided with flow distribution plate and lower flow distribution plate in the shell, be provided with the fin heat transfer pipe between upper flow distribution plate and the lower flow distribution plate, and the fin heat transfer pipe is upper, flow distribution plate and lower flow distribution plate are passed in lower two ends, described outer casing inner wall is provided with the filtration stratum reticulare, the shell upper side is provided with the concentrated solution entrance, outer casing bottom is provided with the weak solution outlet, be provided with deflection plate between the adjacent two fin heat-transfer pipes of the upper surface of described upper flow distribution plate, the fin heat transfer pipe is provided with filming device in the upper end, and the outer wall of fin heat transfer pipe is provided with activated carbon layer.

As preferably, described filtration stratum reticulare is stainless (steel) wire.

As preferably, described fin heat transfer pipe is that interlace mode is arranged.

Compared with prior art, the utility model has the advantage of: the utility model is simple in structure, manufacturing cost is lower, utilize the discarded energy, reduced the operating cost of ammonia water absorbing refrigerator, energy savings, improved the comprehensive utilization of energy rate, outer casing inner wall is provided with the filtration stratum reticulare, prevent that the solid particle in the flue gas from producing impact to the fin heat transfer pipe, reduce the service life of fin heat transfer pipe, the outer wall of fin heat transfer pipe is provided with activated carbon layer, prevents the etchant gas corrosion fin heat transfer pipe in the flue gas, affect the service life of refrigeration machine, the fin heat transfer pipe is provided with filming device in the upper end, has realized that driving heat source gas flows outside the fin heat transfer pipe, solution from top to bottom is the heat transfer type of liquid film flow in pipe, improved heat utilization efficiency.
