Abstract
The invention discloses an energy-saving heat pump dehumidification drying device, comprising a circulating air duct and a fan, wherein a first evaporator, a first condenser and a second condenser are arranged in the circulating air duct in accordance with the direction from an air inlet to an air outlet. The device integrates mechanical dehumidification and heat pump heating into a whole, and adopts two-level heating so as to improve the temperature in a drying room and reduce the humidity in the drying room simultaneously, thus the material drying is fast, the production efficiency is improved effectively, the economic energy-saving effect is outstanding, and the energy-saving effect is at least 50% higher than that of a common heating drying way by using an air source. Because the set is heated indirectly, electric sparks and other combustion sources are not generated, three wastes are not emitted, the noise is low and the safety and environmental conservation are ensured.
Description
Technical field
The present invention relates to a kind of air source heat pump dehumidifier drying equipment.
Background technology
Drying equipment is widely used in food manufacturing, medicine, agricultural and in the dangerous material processing of high risk industries, like gunpowder making, fireworks manufacturing etc.Existing steam heated, combustion indirectly (oil, gas), directly burning waits mode of heating to exist the thermal efficiency not high, and human resources are wasteful, and inferior a large amount of drawbacks are hanged down in Safety and Environmental Protection.General in the past simultaneously drying plant temperature in drying course rises slow, and the highest temperature is spent low.Humidity in the oven dry material can not produce mechanical dehumidifier, can only lean on the hot gas evaporation.Cause drying time long, institute's energy requirement consume significant, and the material type that can dry is single.
Though air source heat pump mode of heating Energy Efficiency Ratio is higher, its principle is to be based upon on the basis of the thermodynamic cycle identical with Refrigeration Technique.This term of heat pump is the operation that comes from the standard heat pump.Low temperature heat energy in the thermal source is promoted to high temperature through the mode of " record " at low-temperature receiver; The distribution of this energy is to import a kind of device that less mechanical energy exchanges bigger heat energy for; Promptly in a closed-loop path, thermodynamic cycle input energy compression also drives working fluid.Fluid evaporates in evaporator room, in condenser condenses.Reach higher temperature levels thereby carry heat through evaporator-condenser, air source heat pump mainly is made up of following four parts: compressor, condenser, evaporimeter and expansion valve.But existing air source equipment is simple, and temperature is low and can not dehumidifier, and required drying time is long, and energy-saving effect is not remarkable.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is that the drying equipment of a kind of energy saving economy, safety and environmental protection is provided.In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is; Energy-saving heat pump dehumidifier drying equipment comprises a circulation air path and blower fan, and the air inlet of said circulation air path all links to each other with hothouse with air outlet; It is characterized in that; Said equipment also comprises first air source heat pump and second air source heat pump, and first air source heat pump comprises first evaporimeter, first condenser, first expansion valve, first compressor, and second air source heat pump comprises second evaporimeter, second condenser, second expansion valve, second compressor; Said first evaporimeter, first condenser, second condenser are according to installing in regular turn in said circulation air path to the direction of air outlet from air inlet.
Adopt technique scheme; The work of first evaporimeter is the process of a desiccant dehumidification; The damp-heat air that comes from hothouse arrives first evaporimeter by the air inducing circulation; Condensation goes out moisture content and the relevant liquid object that contains the composition that volatilizees, and first evaporimeter reclaims the latent heat that comes from the dry chamber and delivers to first condenser simultaneously.
Behind first evaporimeter, the air that is dried carries out heat exchange through first condenser again and by preliminary heating, accomplishes the work of first air source heat pump.
Then, carried out heat exchange and, accomplish the work of second air source heat pump through second condenser by preliminarily heated dry air by heating once more.Got into the hothouse dried material by the air of heating once more then.Periodic duty successively.
Beneficial effect of the present invention is, 1, that heat pump heats the thermal efficiency own is high, heats dry technology with other and compares, and energy-saving efficiency is more than two times of equal electrical heating method.The dehumidifier of this equipment collection machinery; Heat pump heats the drying equipment in one; And adopt the two-stage heating, and having reduced hothouse humidity when improving the hothouse temperature, dry materials has effectively improved production efficiency soon; The economical and energy saving effect is very outstanding, and energy-saving effect is superior to normal air source heat drying at least percent 50.2, since unit be indirect, can not produce electric spark and other burning things which may cause a fire disaster, do not have three waste discharge yet, noise is little, Safety and Environmental Protection be other heat drying mode can't compare.
To combine the accompanying drawing and the specific embodiment that the present invention is described further below.
Description of drawings
Accompanying drawing is a specific embodiment of the invention structural representation.
The specific embodiment
Concrete structure is referring to accompanying drawing; Said energy-saving heat pump dehumidifier drying equipment comprises a circulation air path 1 and blower fan 2; The air inlet 3 of said circulation air path 1 all links to each other with hothouse with air outlet 4; Said equipment also comprises first air source heat pump and second air source heat pump, and first air source heat pump comprises that first evaporimeter 5, first condenser 6, first expansion valve 7, first compressor, 8, the second air source heat pumps comprise second evaporimeter 9, second condenser 10, second expansion valve 11, second compressor 12; Said first evaporimeter 5, first condenser 6, second condenser 10 are according to installing in regular turn in said circulation air path 1 to the direction of air outlet 4 from air inlet 3.The body shell of energy-saving heat pump dehumidifier drying equipment adopts cold-rolled steel sheet to add inorganic thermal insulation board and makes, and fireproof heat insulating property is good; The circulation air path airduct adopts the galvanized iron sheet system of striking to form, and caliber is wide, and ventilation is big; Blower fan can be selected low noise multiple-piece centrifugal blower for use, and air quantity is big, low, the power consumptive province of noise; Compressor adopts split piston compressor high temperature resistance, and the compression heat release is bigger, durable.The integral installation process all adopts reliable ground, carries out the elimination Electrostatic Treatment, and all electric equipment all adopt non-linear type noncontacting switch.Do not produce spark in making all switch startings and working, electric part and quilt oven dry material are isolated, and away from the oven dry material.
