Abstract
The invention discloses a closed low-temperature drying system and a low-temperature drying and energy recycling method. The system comprises a material drying room and an air drying space, wherein the air drying space is internally provided with an evaporator and a condenser. The material drying room and the air drying space are communicated through a drying air inlet channel and a drying air return channel and then form a closed drying air circulation system. The air drying space is at least internally provided with the evaporator and the condenser, and the air drying space, an external throttling device and a compressor form a complete refrigerating system. The method comprises the steps that the heat absorption process of the evaporator of the refrigerating system is utilized for completing cooling of air of the air drying space, water is separated after the air is cooled and condensed, the water is drained out, meanwhile, heat emitted when the water is separated after the air is condensed is returned to the air inside the air drying space through the rear condenser, then, the air enters the material drying room through a circulating fan and is used for evaporation and heat absorption of water in materials to be dried, and the energy recycling process is completed.

Description
Technical field
What the present invention relates to is a kind of method of closed low temperature drying system and low temperature drying and energy recycling, can be applicable in automobile, pharmacy, food processing, meat packing, environmental protection industry, as paint drying, colouring agent are dry, labour protection Rubber gloves production line, vegetable products (as dry in mother chrysanthemum, Chinese medicine etc.), food production, fabric drying, draw in the pretreated dry run of rubbish.
Technical background
In traditional drying materials method and apparatus, what generally adopt is to provide heat to air and material, the one, improve air themperature, and absorb more moisture content; The 2nd, temperature of charge is raise, moisture content is more easily run out from material.But the moisture content that hot-air absorbs is limited, so in a limited space---in hothouse, remove moisture content from hothouse, only way is that the moisture content of running out in material is discharged in environment, and when release, energy loses simultaneously.Therefore, the shortcoming of existing drying system is: 1, high energy loss; 2, discharge in steam process, usually follow a lot of peculiar smell to be also discharged in environment, cause ambient influnence; 3, in drying course, dry indoor air humidity approaches saturated, and the material drying quality causing is unstable, as the blushing in painted or paint drying process.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned existence, provide that a kind of system architecture is reasonable, method is simple and reliable, the method for the obvious closed low temperature drying system of energy-saving effect and low temperature drying and energy recycling.
The object of the invention is to complete by following technical solution, a kind of closed low temperature drying system, it comprises a dry materials chamber, one is built-in with the air dry place of evaporimeter and condenser, between described dry materials chamber and air dry place, forms an enclosed dry air circulatory system by a dry air air intake passage and dry air return air channel after being interconnected; In described air dry place, be at least mounted with an evaporimeter and a condenser, and formed a complete refrigeration system with outside throttling arrangement and compressor.
The evaporimeter of installing in described air dry place is placed in the mobile upstream of dry air, and the condenser of installing is placed in the mobile downstream of dry air; Between described compressor and throttling arrangement, be serially connected with a compressor high temperature protection valve in parallel with evaporimeter; Connection oral area near dry air air intake passage in described air dry place is provided with circulating fan.
The evaporimeter of two adjacent layouts and the condenser of two adjacent layouts are installed in described air dry place, and described evaporimeter and condenser form respectively independently dual unit cooling system with throttling arrangement and the compressor of peripheral hardware separately.
A kind ofly utilize above-mentioned closed low temperature drying system to carry out the method for low temperature drying and energy recycling, described method is: the evaporimeter endothermic process of utilizing refrigeration system, complete first the air of air dry place is lowered the temperature, condensation moisture content discharge after air cooling-down, simultaneously air setting is separated out to moisture content and liberated heat is returned the air in air dry place by rearmounted condenser, air afterwards enters dry materials chamber through circulating fan, for the water evaporates heat absorption in material to be dried, complete energy recycling process.
The present invention is in described method, utilize the mode of two-stage refrigeration, two evaporimeters and two condensers that utilize the two cover cooling systems of installing in air dry place, the air being dried very much in air dry place, for the dry materials of dry materials chamber.
The present invention is mainly by the evaporimeter of refrigeration system and condenser, carries out with the different phase that the air in closed system is flowed through in system inner cyclic process the process that heat exchange completes removal moisture content and obtains energy recycling.System itself is externally acting not, does not externally carry out heat exchange, and therefore, drying system itself does not produce any energy loss; From but the present invention has the features such as system architecture is reasonable, method is simple and reliable, and energy-saving effect is obvious.
