Abstract

The utility model discloses an integrated effective cooling drier which is characterized in that the calandria (2b) of a preposition forecooler (2), the coil of a condenser (6a), the calandria (4b) of a heat exchanger (4) and a common fin (7) swell and form an integration. The condenser (6a) is arranged beneath the preposition forecooler (2), and a common fan (8) and the condenser (6a) conduct cooling and reducing the temperature to the preposition forecooler (2) and the heat exchanger (4) in common. The heat-exchanging processes of the preposition forecooler (2) and an evaporator (3) are mutually inverse. Compared with the prior art, the utility model has the following advantages: 1) the common fan (8) and the condenser (6a) conduct cooling and reducing the temperature to the hot-air in common, so the dehumidification effect to the hot-air is improved effectively; 2) the power consumption decreases more than 30 percents in the situation of equal dehumidification effect; 3) on the ground of the operating condition, the evaporator does not belong to the pressure containers, and brings much convenience to the safe handling and the monitoring of the cooling driers. 4 the volume of the complete machine contracts remarkably, the connecting pipe shortens, the conformation is compact, and the production cost is low.

Description

The energy-saving cooling driers of integrated

Technical field

The utility model relates to the drying equipment of a kind of air or gas, the energy-saving cooling driers of particularly a kind of integrated.

Background technology

Traditional air cooling driers is made of dehydrating unit, refrigeration system, electric control gear, dehydrating unit comprises the front end filter, the preposition cooler that gives, evaporimeter, heat exchanger, the rear end filter, refrigeration system is made up of cold medium compressor, condenser, evaporimeter, heating power expansion valve, reservoir, the preposition relevant parts that give cooler, heat exchanger and refrigeration system are installed in the same shell body discretely, and front end filter and rear end filter are installed in the shell body outside by the user scene.The defective of traditional 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 (being hot-air) reduces heat transfer efficiency in its gap place bypass; 3) used evaporimeter belongs to pressure vessel, increases difficulty for safety and monitoring; 4) machine volume is bigger, the production cost height.

Summary of the invention

The purpose of this utility model provides the energy-saving cooling driers of a kind of integrated, overcomes the defective that traditional cooling driers exists, and can significantly improve effect on moisture extraction, and machine volume dwindles, and energy consumption descends, and production cost is low.

The energy-saving cooling driers of a kind of integrated, comprise filter 1, the preposition cooler 2 that gives, evaporimeter 3, heat exchanger 4, filter 5, refrigeration system 6 and condenser 6a thereof, its thermal expansion valve 6b, meter 6c, compressed air passes through filter 1, the preposition cooler 2 that gives, evaporimeter 3 successively, heat exchanger 4, filter 5, cold-producing medium successively pass through the coil pipe of condenser 6a, thermal expansion valve 6b, the coil pipe 3a of evaporimeter 3, it is characterized in that: the preposition comb 2b that gives cooler 2, the coil pipe of condenser 6a, the comb 4b of heat exchanger 4 and shared fin 7 expand and strike up partnership, and condenser 6a is arranged in preposition below of giving cooler 2, and common fan 8 and condenser 6a are jointly to the preposition cooler 2 that gives, heat exchanger 4 cooling of lowering the temperature; Prepositionly give cooler 2 and evaporimeter 3 its heat exchanging process are reverse each other.

With prior art relatively, the utlity model has following outstanding advantage: 1) prepositionly give the coil pipe of comb 2b, the condenser 6a of cooler 2, the comb 4b and the shared fin 7 of heat exchanger 4 is connected as a single entity, common fan 8 and condenser 6a to hot-air cooling cooling, can improve the effect on moisture extraction to hot-air jointly effectively; 2) under equal effect on moisture extraction situation, reduce power consumption more than 30%; 3) all parts are combined into one, and are vertical structure, do not belong to pressure vessel according to the working condition evaporimeter, bring many convenience for thus the safe handling and the monitoring of cooling driers; 4) all parts all are installed in the same shell body, and machine volume significantly dwindles, and connecting pipe shortens, compact conformation, and production cost is low.

The specific embodiment

Embodiment 1

The comb 4b of the preposition coil pipe that gives comb 2b, the condenser 6a of cooler 2, heat exchanger 4 and shared fin 7 expand and strike up partnership, the coil pipe 3a of the coil pipe of cold-producing medium by condenser 6a, thermal expansion valve 6b, evaporimeter 3, coil pipe 3a and fin 3b expand and become one, the coiled tube arrangements of condenser 6a is below comb 2b, meter 6c is installed on the outlet conduit of coil pipe 3a, common fan 8 and condenser 6a be jointly to shared fin 7, comb 2b, the comb 4b cooling of lowering the temperature, and coil pipe 3a is to the cooling of lowering the temperature of fin 3b and the hot-air that passes fin 3b gap.Cold-producing medium adopts alternative chlorofluoro carbon R134a.The preposition coil pipe that gives comb 2b, the condenser 6a of cooler 2, evaporimeter 3 coil pipe 3a, the comb 4b of heat exchanger 4 all adopt copper pipe.Prepositionly give cooler 2 and evaporimeter 3 its heat exchanging process are reverse each other.

From the hot-air of air compressor successively by entering the bottom of evaporimeter 3 behind filter 1 and preposition discharge 2a, the comb 2b that gives cooler 2, the discharge 2c, pass the gap of the fin 3b of evaporimeter 3 from bottom to top, through discharge 4a, comb 4b, discharge 4c and the filter 5 of heat exchanger 4, become clean air again.Cold-producing medium is 60 ℃ in the coil pipe import department temperature of condenser 6a, and the exit temperature is 30 ℃ of environment temperatures, and cold-producing medium is 0 ℃ in the coil pipe 3a of evaporimeter 3 import department temperature, and the exit temperature is 5 ℃; Hot-air is 4Mpa in filter 1 inlet pressure, and temperature is 70 ℃, and through the preposition cooler 2 that gives, temperature is 25 ℃ when entering evaporimeter 3, and hot-air is sent clean air through heat exchanger 4 and filter 5 in filter 5 exits, and outlet temperature is 25 ℃.The hot-air of this cooling driers is by 45 ℃ of coolings in the preposition process of giving cooler 2, by heating up 25 ℃ in heat exchanger 4 processes.All parts all are contained in outward on the shell body, filter 1, prepositionly give condensed water that cooler 2, evaporimeter 3, heat exchanger 4 and filter 5 come out and are pooled to the shell body bottom and discharge.
