Its advantages are compact structure, small size, low cost, high cooling and demoistening effect, and high heat exchanging efficiency.

Description

Energy saving integral type cooling driers

Technical field

The present invention relates to the dry decontamination equipment of a kind of air or gas, particularly a kind of energy saving integral type cooling driers.

Background technology

Traditional air cooling driers is by dehydrating unit, refrigeration system, electric control gear constitutes, dehydrating unit comprises the front end filter, the preposition cooler that gives, evaporimeter, heat exchanger, the rear end filter, refrigeration system is by cold medium compressor, condenser, evaporimeter, heating power expansion valve, reservoir is formed, Fig. 1 is existing air cooling driers structural representation, and 1 is filter among the figure, and 2 are the preposition cooler that gives, 3 is evaporimeter, 4 is heat exchanger, and 5 is filter, and 6 is refrigeration system, 6a is a condenser, compressed air from air compressor passes through filter 1 successively, the preposition cooler 2 that gives, evaporimeter 3, heat exchanger 4, filter 5, filter 5 transfers out the compressed air of clean dried, uses for follow-up equipment.Preposition give cooler 2, heat exchanger 4 and comprise condenser 6a, evaporimeter 3 is installed in the same housing discretely at the relevant parts of interior refrigeration system, filter 1 and 5 is installed in hull outside by the user scene.The defective of this air cooling driers is: 1) the discrete installation of each parts, and it is big to take volume, and connecting pipe is long, and it is bigger to leak probability; 2) evaporimeter 3 adopts horizontal drum type brake evaporimeter, and compressed air reduces heat transfer efficiency in its gap place bypass; 3) used evaporator shell belongs to pressure vessel, increases difficulty for safety and monitoring; 4) machine volume is bigger, the production cost height.

Summary of the invention

A kind of energy saving integral type cooling driers, comprise filter 1, the preposition cooler 2 that gives, evaporimeter 3, heat exchanger 4, filter 5, refrigeration system 6 and condenser 6a thereof, compressed air is successively by filter 1, preposition cooler 2, heat exchanger 4, the filter 5 of giving, cold-producing medium passes through the coil pipe of evaporimeter 3 and condenser 6a respectively, it is characterized in that: all parts of cooling driers all are installed in the inside of complete machine housing, and prepositionly give cooler 2 and condenser 6a unites two into one, and evaporimeter 3 and heat exchanger 4 unite two into one; In the preposition structure of giving cooler 2 and condenser 6a that unites two into one, preposition discharge 2a, the copper pipe 2b that gives cooler 2, the compressed air breather line that discharge 2a ' is constituted are arranged in the top of casing, the coil pipe of condenser 6a is installed in the bottom of this casing, and both have shared fin 2c and fan 2d; In the evaporimeter 3 that unites two into one and the structure of heat exchanger 4, both are provided with shared fin 3b, the coil pipe 3a of evaporimeter 3 is installed in the top of casing, enter the bottom of heat exchanger 4 from the preposition compressed air that gives cooler 2, the gap of fin 3b, comb 4a, remittance tracheae 4b, escape pipe 4c constitute compressed air channel, collect in bottom in the complete machine housing from the water of filter 1, fin 2c, fin 3b, filter 5, and draw the complete machine outside.

With prior art relatively, the present invention has following outstanding advantage: 1) prepositionly give cooler 2 and condenser 6a unites two into one, can improve compressed-air actuated cold cooling-down effect and the effect on moisture extraction thereof of giving effectively; 2) evaporimeter 3 and heat exchanger 4 unite two into one, and can improve heat exchanger effectiveness and effect on moisture extraction effectively, reduce power consumption 30%; 3) evaporimeter 3 and heat exchanger 4 unite two into one, and are vertical structure, do not belong to pressure vessel according to this evaporimeter of working condition, bring many convenience for thus the safe handling and the monitoring of cooling driers; 4) all parts that comprise filter 1 and 5 all are installed in the same housing, and machine volume significantly dwindles, and connecting pipe shortens, compact conformation, and power consumption reduces, and production cost is low, and the user saves and is using the on-the-spot trouble that 2 filters are installed simultaneously.
