Abstract
The utility model discloses a waste heat defrosting type heat pump dryer. The heat pump dryer comprises a heat pump dryer body and a drying room, wherein the drying room is located at one side of the heat pump dryer body and is communicated with the heat pump dryer through a hot air inlet (h) and an air outlet (k), a waste heat recovery device (e) is arranged between a condenser (c) and an evaporator (a) of the heat pump dryer body, an air door (f) is arranged on the waste heat recovery device (e), and a fresh air inlet (g) and a return air inlet (n) are formed in the air door (f). According to the heat pump dryer, the problem of frosting on the surface of an outdoor heat exchanger of a heat pump unit in a winter operation condition can be effectively solved, and an aim of normally operating the heat pump unit under the winter operation condition can be realized by the functions of preventing frosting and frost dissolving. The heat pump dryer has the characteristics of being simple in structure and convenient to use and realizing energy conservation and environmental protection.
Description
Technical field
The utility model belongs to high-temperature residual heat drying technology field, and what relate generally to is a kind of waste heat defrosting heat pump dryer, is applicable to the defrosting mode of heat pump winter condition.
Background technology
According to statistics, the dry energy that consumes accounts for the more than 25% of the whole energy resource consumption of China.China's current drying major part is traditional drying equipment, and conventional drying equipment energy utilization rate is low by approximately 30%, and environmental-protecting performance is poor.Heat pump drying technology is the energy-conserving and environment-protective drying equipment developing in recent years, compares traditional drying method energy-conservation more than 50%.But source pump is prone to the problem of heat exchanger surface frosting in the winter time under operating condition, cause source pump in the winter time under operating condition, because the problem that causes leaving air temp and baking room temperature to reduce in heat decay and defrost process appears in heat exchanger frosting, badly influence the heat exchange property of heat exchanger.
Summary of the invention
The purpose of this utility model produces thus, a kind of waste heat defrosting heat pump dryer is proposed, solve the source pump frosting problem on outdoor heat exchanger surface under operating condition in the winter time, by the function of pre-antifrost and molten frost, realize the source pump object of normal operation under operating condition in the winter time.There are features simple in structure, easy to use, energy-conserving and environment-protective.
For realizing above object, the utility model is by the following technical solutions: a kind of waste heat defrosting heat pump dryer, comprise heat pump dryer, baking room and waste-heat recovery device, baking room is positioned at a side of heat pump dryer, be communicated with heat pump dryer by hot blast import and exhaust outlet, between the condenser of heat pump dryer and evaporimeter, arrange and waste-heat recovery device, and on waste-heat recovery device, be provided with air door, on described air door, there is fresh inlet and return air inlet.
The utility model, by waste-heat recovery device being set on existing heat pump dryer, has been realized the utilization of waste heat, and the waste heat of discharge is for the defrosting of heat pump.When outdoor environment temperature is higher than when setting value: the hot and humid air of exhaust outlet and the Cryogenic air of air inlet are carried out heat exchange, realize the waste heat recovery of exhaust outlet.Winter condition is when outdoor environment temperature is lower than when setting value: the hot and humid air of exhaust outlet is directly discharged into above outdoor frosting heat exchanger, realizes the function of pre-antifrost and molten frost.There are features simple in structure, energy-conserving and environment-protective.Not only make the exhaust heat of baking room make full use of, and solve the source pump frosting problem on outdoor heat exchanger surface under operating condition in the winter time, by the function of pre-antifrost and molten frost, realize the source pump object of normal operation under operating condition in the winter time.There are features simple in structure, easy to use, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: a, evaporimeter, b, compressor, c, condenser, d, throttling arrangement, e, waste-heat recovery device, f, air door, g, fresh inlet, h, hot blast import, k, exhaust outlet, m, secondary returning air port, n, return air inlet, p, blower fan.
The specific embodiment
By reference to the accompanying drawings, by the mode of embodiment, the utility model is further illustrated as follows, but the utility model does not limit to following enforcement.
As shown in Figure 1: a kind of waste heat defrosting heat pump dryer described in the present embodiment mainly comprises by evaporimeter a, compressor b, condenser c, throttling arrangement d, heat pump dryer and waste-heat recovery device e and the baking room of blower fan p composition, the exhaust outlet of the compressor b of heat pump dryer is connected with condenser c by pipeline, condensation a device c is connected with throttling arrangement d, throttling arrangement d is connected with evaporimeter a, evaporimeter a is connected with the air entry of compressor b, waste-heat recovery device e is arranged between condenser c and evaporimeter a. and waste-heat recovery device adopts mature full recuperation of heat structure at present.On waste-heat recovery device e, be provided with air door f, on air door f, there is fresh inlet g and return air inlet n.Baking room is positioned at a side of heat pump dryer, be communicated with heat pump dryer by the hot blast import h, the exhaust outlet k that are arranged on wall, be provided with axial flow blower at hot blast import h position, be provided with three-way pipeline at exhaust outlet k position, part hot blast forms secondary return air by secondary returning air port m under the effect of condensation fan, part hot blast is under the effect of heat reclamation device, by return air inlet n.
Operation principle of the present utility model is as follows:
Heat pump circulating system: compressor b discharges the refrigerant gas of HTHP near the condenser c being positioned at baking room, the gas that condenser c enters baking room by acting on of axial flow blower carries out heat exchange, self temperature reduces, the temperature of gas raises, after energy exchange, cold-producing medium becomes the gas-liquid two-phase of middle temperature high pressure, cold-producing medium becomes the refrigerant liquid of cryogenic high pressure, the refrigerant liquid that becomes low-temperature atmosphere-pressure by throttling arrangement d enters evaporimeter a, by the heat exchange of evaporimeter a and outside air, the refrigerant gas that becomes low-temperature atmosphere-pressure after the heat of absorption outside air enters compressor and circulates.
Baking room air circulation: fresh inlet g is entering waste-heat recovery device e, with carry out heat exchange through the return air of secondary returning air port m baking room exhaust outlet k, after temperature increase with after condenser c temperature further promotes, enter baking room through fresh inlet h and circulate.
Waste heat defrosting: by set temperature testing agency and controller, in the winter time under the working condition of operation, in the time outdoor environment temperature being detected lower than setting value, controller judges that unit need to enter pre-antifrost and defrosting mode, sends instruction, and air door f opens, return air inlet n closes, the high-temperature gas of discharging from drying chamber carries out heat exchange with outdoor heat exchanger under the effect of blower fan p, and heat is absorbed for defrosting and pre-antifrost by heat exchanger.What temperature testing organization and controller adopted is all conventional technology, does not repeat them here.
