Description
Technical field
The utility model relates to a kind of dehumidifying heat pump, relates in particular to a kind of with the novel dehumidifying heat pump that be used for resource regeneration process drying operation of heat pump as thermal source.
Background technology
Stoving process process in the resource regeneration processing procedure generally is to utilize hot dry wind to take away moisture in the regenerated resources, provides water evaporates needed heat.At present, the heating of air has multiple mode, that generally adopts has two kinds: a kind of is the high-temperature flue gas preheated air that produces by tail gas and boiler operatiopn, the tail gas and the high-temperature flue gas that utilize fuel combustion to produce add hot-air, and the air behind the pre-heating temperature elevation enters the drying operation that dryer carries out resource regeneration.This mode of heating has made full use of the heat of tail gas and high-temperature flue gas, but tail gas and high-temperature flue gas contain a lot of solid particle polluters, influence pipe heat-transfer, and increases gas discharging pre-processing device.Also having a kind of is to pass through Steam Heating: adopt coal, fuel oil, the coal gas drying device as supplying heat source, this mode of heating, except that drying equipment, also need to invest the numerous and diverse administrative expenses of huge boiler room, boiler plant and payment, as increase environmental protection facility, bookkeeping personnel, coal-burning boiler also will be invested the stockyard of coal, the transportation of coal and slag etc.Also have some to adopt electrical heating to come the preheating surrounding air, but power consumption is big.
More than these methods all be to obtain dry required heat by simple heating, the raising air themperature is come garbage drying, hot blast only provides the heat energy that water evaporates needs, do not consider of the influence of the humidity of air to water evaporates, the relative humidity of general air is low more, and partial pressure of water vapor is more little, and drying efficiency is high more, therefore above these methods are under the big occasion of air humidity, and drying efficiency is not high.And all there is the secondary pollution problem of environment in these methods, hot-air enters in the drier the heat transferred material, make moisture vaporization wherein and be the free band of gas to go out drier, the air that goes out drier becomes the waste gas that temperature is low, water content is many, directly enter environment together, do not realize the energy-conserving and environment-protective of real meaning.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and can satisfy the dry dehumidifying heat pump of resource regeneration with circulation hot dry wind demand, and this equipment have energy consumption cost low, environment is not had any pollution, higher energy efficiency indexes and better engineering adaptability is arranged.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of resource regeneration heat pump drier comprises indoor set and off-premises station, and indoor set comprises evaporimeter and reheater condenser again, and it is at air inlet and evaporimeter, the reheater condenser place is provided with heat-recovery circulating system again.
Wherein, described heat-recovery circulating system comprises the recuperation of heat endotherm section that is arranged on the air inlet place and is arranged on evaporimeter, the recuperation of heat heat release section between the reheater condenser again; The output of recuperation of heat endotherm section links to each other with water circulating pump by first water valve, and water circulating pump links to each other with the input of recuperation of heat heat release section by second water valve, and the output of recuperation of heat heat release section links to each other with the input of recuperation of heat endotherm section; Captation links to each other with water circulating pump by the 3rd water valve.
Wherein, described recuperation of heat endotherm section, recuperation of heat heat release section are coil exchanger; Described first water valve, second water valve are butterfly valve; Described the 3rd water valve is the hand valve.
Heat pump cycle process: reheater condenser and outdoor condenser again in the refrigerant gas inlet chamber of the HTHP of discharging from compressor, become the refrigerant liquid of cryogenic high pressure after the air setting cooling, then pass through stop valve, liquid reservoir, device for drying and filtering, magnetic valve enters expansion valve, after the expansion valve throttling, the cold-producing medium vapour-liquid coexisting body that becomes low-temp low-pressure enters evaporimeter, in evaporimeter, absorb airborne heat and be evaporated, enter compressor after becoming the refrigerant gas of low-temp low-pressure, by the refrigerant gas of compressor compression becoming HTHP, continuous refrigerated dehumidification so continuously circulates again.
The recuperation of heat circulation theory is: the high temperature glycol liquid of discharging from water circulating pump is by the recuperation of heat heat release section, become the liquid of low temperature by the air cooling-down of low temperature, then enter the recuperation of heat endotherm section, become high-temperature fluid by the high temperature air heating, be recycled water pump again and suck, circulation constantly realizes transfer of heat so continuously.
Air handling process: during equipment operation, humid air is under the effect of ventilation blower, and the recuperation of heat endotherm section of flowing through behind air cleaner carries out precooling to air, reduces the temperature of air; The evaporimeter of then flowing through, contact with evaporator surface, because the evaporator surface temperature is lower than the dew-point temperature of humid air, airborne water vapour just cooling condenses into water droplet, be gathered in the water spraying tray and discharge by drainpipe, the temperature and the water capacity of air are reduced simultaneously, the air that falls after wetting carries out preheating by the recuperation of heat heat release section to the air-out of dehumidifying section again, the reheater condenser of flowing through at last again is heated (need not other thermals source, reach energy-conservation purpose), send into space specified after making air after the heating reach designing requirement (dry-bulb temperature t=60～70 ℃), guarantee that like this leaving air temp of air-out is than higher, relative humidity is also lower simultaneously, absorbs moisture to improve hot-air, carry the ability of moisture, improve the drying efficiency of rubbish.
Beneficial effect: (1) adopts heat pump cycle can reclaim the contained sensible heat and the latent heat of damp-heat air of discharging in the dry kiln, the energy that needs the user to import has only the power consumption (and a small amount of power consumption of auxiliary vigour part such as blower fan) of heat pump compressor, and heat pump has the advantage that less energy can obtain a large amount of heat energy that consumes, therefore energy obtains fully and rationally utilizing, and is energy-efficient; (2) adopt heat recovery system, reduce the load of heat pump cycle, further energy-conservation, energy-saving efficiency about 10%; (3) because the overall process of heat pump drying rubbish is to carry out, do not need environment hydrofuge towards periphery in closed system, can not discharge gas harmful, frowzy simultaneously yet, environmental protection, health, this compares with other drying means, is the advantage of a uniqueness; (4) drying medium in the heat pump drying device is in the circulation of the space of sealing; Be not subjected to the influence of extraneous weather conditions, all even runnings under identical conditions throughout the year are so dry mass is stable.Because the component of refuse complex structure, hydrophilic power is stronger; The heat pump drying temperature not only can be 60～70 ℃ of adjustings, and can control the humidity of hothouse, satisfy the ideal conditions of drying garbage.Evidence, the moisture content of dry finished product can satisfy customer requirements.
