Description

Heat pump spray dryer
Technical field
The utility model is related to dry field more particularly to a kind of heat pump spray dryers.
Background technology
Conventional spray dryer also has thermal energy, 60~100 DEG C of tail gas humid air to be in operation in the gas of its discharge It directly empties, wastes many energy consumptions, while also resulting in greenhouse effects, welding.
Utility model content
The technical problems to be solved in the utility model is:Overcome the deficiencies of the prior art and provide a kind of heat pump spray drying Machine solves the defect that cannot efficiently use thermal energy in tail gas humid air in the past.
Technical solution adopted by the utility model to solve its technical problems is:A kind of heat pump spray dryer, including spray Mist drying machine, the spray dryer have blast pipe and discharge pipe, electric heater, the outlet air are provided on the blast pipe Circulating fan is provided on pipe;
Further include heat pump, the heat pump includes babinet, be provided in the babinet evaporator, compressor, condenser and Throttle valve connects gaseous state pipeline, compressor is provided on the gaseous state pipeline between the evaporator outlet and condenser inlet, Liquid pipeline is connected between the condensator outlet and evaporator, and throttle valve, the gas are provided on the liquid pipeline Circulation line is formed between state pipeline, liquid pipeline, evaporator and condenser, refrigerant is provided in the circulation line;Institute It states and offers gas feed and gas vent on babinet, the evaporator is arranged at babinet gas feed, and the condenser is set It sets in babinet gas outlet;
The spray dryer discharge pipe is connect with heat pump babinet gas feed, the spray dryer blast pipe and heat pump Babinet gas vent connects.
Further, cyclone dust collectors and pulsed bag-type dust are provided on the discharge pipe of the circulating fan upstream Device.
Further, it is provided with condensation water collection box below the evaporator.
The utility model has the beneficial effects that:The damp and hot sky containing thermal energy being discharged by heat pump absorption dehydration machine escape pipe Gas, evaporator remove the moisture content in damp-heat air and absorb thermal energy, make to become cold dry air after its heat pump babinet of entering, pass through The effect of refrigerant in heat pump converts the thermal energy that evaporator absorbs to condenser, and cold dry air is when process condenser is discharged It waits to be heated and becomes heated dry air, this part heated dry air continues the heat energy source dried as spray dryer.
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the utility model heat pump spray dryer schematic diagram;
Wherein, 1, spray dryer, 2, evaporator, 3, compressor, 4, condenser, 5, throttle valve, 6, electric heater, 7, rotation Wind deduster, 8, pulsed bag filter, 9, circulating fan.
Specific implementation mode
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1, a kind of heat pump spray dryer 1, including spray dryer 1, spray dryer 1 have blast pipe and Discharge pipe is provided with electric heater 6 on blast pipe, circulating fan 9 is provided on discharge pipe.
Further include heat pump, heat pump includes babinet, and evaporator 2, compressor 3, condenser 4 and throttle valve are provided in babinet 5, gaseous state pipeline is connected between the outlet of evaporator 2 and 4 import of condenser, compressor 3, condenser are provided on the gaseous state pipeline Liquid pipeline is connected between 4 outlets and 2 import of evaporator, throttle valve 5, gaseous state pipeline, liquid are provided on the liquid pipeline Circulation line is formed between pipeline, evaporator 2 and condenser 4, refrigerant is provided in the circulation line;It is offered on babinet Gas feed and gas vent, evaporator 2 are arranged at babinet gas feed, and condenser 4 is arranged in babinet gas outlet;Spray 1 discharge pipe of mist drying machine is connect with heat pump babinet gas feed, and 1 blast pipe of spray dryer connects with heat pump babinet gas vent It connects.2 lower section of evaporator is provided with condensation water collection box.
It is provided with cyclone dust collectors 7 and pulsed bag filter 8 on the discharge pipe of 9 upstream of circulating fan.
When operation, hot and humid gas is discharged from escape pipe in spray dryer 1, and hot and humid gas is introduced heat by circulating fan 9 Pump box body, hot and humid gas first act on evaporator 2, and evaporator 2 removes the moisture content in damp-heat air and absorbs thermal energy, and water is fallen into In the collecting box of lower section, make to become cold dry air after its heat pump babinet of entering, by the effect of refrigerant in heat pump, by evaporator 2 The thermal energy of absorption is converted to condenser 4, and cold dry air is heated when babinet is discharged by condenser 4 to become heated dry air, Heated dry air enters the work thermal energy that spray dryer 1 is re-used as spray dryer 1 under the heating of electric heater 6 again.
Heat pump spray dryer 1 is more energy efficient, is effectively utilized the thermal energy of this partial HAT of drying machine discharge, moist empty Rapid exothermic condensation Cheng Shui is ejected after gas enters evaporator with heat pump 2 under fan action, that is to say, that water is in spray dryer 1 How much heat is inside absorbed, inevitable to be absorbed out of evaporator with heat pump 2, the low level of steam is transmitted to again after capable of being transmitted to refrigerant in humid air Circulation air heats up.
And the heat pump that dehumidifies is equivalent to an incubator, and need not carry out heat exchange to the external world because being closed system, it is only necessary to defeated Enter small part electric energy, so that it may to be transmitted to circulation air again after the low level of the steam evaporated in system can be transmitted to refrigerant, follow Ring dry air is further heated up by heater into spray dryer 1 again goes dry feed liquid, emission-free discharge to reduce tail Flash Gas Compression Skid System.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real It is not limited to the contents of the specification with novel technical scope, it is necessary to which its technology is determined according to right Property range.
