Heat pump techniques is the new energy technology that receives much attention in the whole world in recent years." pump " that people were familiar with is a kind of plant equipment that can improve potential energy, mainly is that water is extracted into a high position from low level such as water pump.And " heat pump " is a kind of low grade heat energy that can obtain from natural air, water or soil, and through the electric power acting, providing can be by the device of the used high-grade heat energy of people.
The Teat pump boiler kind is a lot of in the market, mainly contains solar energy boosting type, the three kinds of series in water source and air source.Solar energy assisted heat pump is a kind of heat pump techniques that heat pump is used in combination with heliotechnics; Water resource heat pump is that the water source (more than 20 ℃) that utilizes uniform temperature is media with the cold-producing medium as thermal source, heat absorption in the water source is heated by compressor compresses, to reach heating and to produce the purpose of hot water, water resource heat pump must have the water source of uniform temperature and flow by heat exchanger and cold water heat-shift; Air source heat pump obtains heat with the water resource heat pump similar approach from air and adds hot water.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of drying system based on heat pump and using method thereof are provided, adopt the heat pump principle, having utilized to greatest extent can in the facility environment, and reduction system as far as possible effluxes energy loss, thereby reaches the purpose of energy-saving and emission-reduction.The present invention had both complied with the requirement of national energy-saving and emission-reduction, also in order to find new growth engines to our company, was user's creation of value, won user's trust, made enterprise and user realize doulbe-sides' victory.
The objective of the invention is to solve by the following technical programs:
Based on the drying system of heat pump, comprise the hot-air system and the heat pump that are set up in parallel; Described heat pump comprises condenser, evaporimeter, compressor bank and choke valve; The blast pipe of described hot-air system passes condenser; Compressor bank and choke valve have been arranged in parallel between described condenser and the evaporimeter.
Described evaporimeter is provided with the pipeline that is communicated with low-temperature heat source; Pipeline is provided with pump.
Described low-temperature heat source is underground water.
The using method of described drying system is set up in parallel hot-air system and heat pump; Described heat pump comprises condenser, evaporimeter, compressor bank and choke valve; The blast pipe of hot-air system is passed condenser; Compressor bank and choke valve are set between condenser and the evaporimeter, and evaporimeter is provided with the pipeline that is communicated with low-temperature heat source; Pipeline is provided with pump.
Native system is in when operation, and the liquid refrigerant of low-temp low-pressure (for example freon) at first absorbs heat and is vaporized into low-pressure steam from low-temperature heat source (underground water) in evaporimeter.Refrigerant gas is compressed into the steam of HTHP in compressor then, and this high temperature and high pressure gas with the new air intake of heat transferred, improves new wind-warm syndrome degree at the condenser place, reaches the purpose of the new wind of preheating.At this moment, refrigerant gas is condensed into the normal temperature high voltage liquid refrigerant.Remove moisture and impurity from the liquid refrigerant drying filter that condenser comes out, the magnetic valve of flowing through becomes the low-temp low-pressure liquid refrigerant and enters evaporimeter after heating power expansion valve throttling step-down.The heat that the low-temp low-pressure liquid refrigerant absorbs recirculated water in the evaporimeter evaporation that keeps all becomes the overheated dry flue gas of low-temp low-pressure during the arrival evaporator outlet, return the compressor air suction valve.Circulate so repeatedly, reach the purpose of the new wind of preheating.
The invention has the beneficial effects as follows:
Fresh wind through preheating enters hot air circulating system, participates in the hot-air drying process of printing machine, compounding machine, coating machine.Utilize heat pump that new wind-warm syndrome degree is raise more than 10 ℃, effectively reduce the heating power of complete machine, reached purpose of energy saving.
Description of drawings
Fig. 1 is on-line Application method schematic diagram of the present invention;
Wherein: 1 is condenser; 2 is compressor bank; 3 is evaporimeter; 4 is choke valve; 5 is pump; 6 is low-temperature heat source; 7 is new air-out; 8 are air draft; 9 is first drying box; 10 is second drying box; 11 is the N-1 drying box; 12 is the N drying box.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 1, adopt heat pump to take full advantage of energy in the external environment condition low-temperature heat source, effectively reduction system input energy reaches purpose of energy saving, because heat pump can heat pump can utilize in the low-temperature heat source can, 3 to 4 times heat energy of self institute's energy requirement is sent to high temp objects from cryogenic object.Native system is in when operation, and the liquid refrigerant of low-temp low-pressure (for example freon) at first absorbs heat and is vaporized into low-pressure steam from low-temperature heat source (underground water) in evaporimeter.Refrigerant gas is compressed into the steam of HTHP in compressor then, and this high temperature and high pressure gas with the new air intake of heat transferred, improves new wind-warm syndrome degree at the condenser place, reaches the purpose of the new wind of preheating.At this moment, refrigerant gas is condensed into the normal temperature high voltage liquid refrigerant.Remove moisture and impurity from the liquid refrigerant drying filter that condenser comes out, the magnetic valve of flowing through becomes the low-temp low-pressure liquid refrigerant and enters evaporimeter after heating power expansion valve throttling step-down.The heat that the low-temp low-pressure liquid refrigerant absorbs recirculated water in the evaporimeter evaporation that keeps all becomes the overheated dry flue gas of low-temp low-pressure during the arrival evaporator outlet, return the compressor air suction valve.Circulate so repeatedly, reach the purpose of the new wind of preheating.
