Description
Technical field
The present invention relates to food processing equipment technical field, more specifically, relate to a kind of noodle drying process heat recovery heat pump air conditioning system, reclaim the used heat of discharging in vermicelli baking room.
Background technology
Vermicelli industry is Chinese national economy organic component, and it is exactly that Reasonable Regulation And Control is dried in road temperature, humidity and the mobile speed as the air of Transfer Medium that vermicelli are dried.Different baking stages is taked different counter-measures, makes the vaporization of moisture diffusion in vermicelli, transfers in air, to form humid air and be pulled away, and finally obtains superior in quality vermicelli.Vermicelli are dried and are generally all adopted convection current heating power oven drying method, utilize primary energy (coal or natural gas etc.) to heat-conducting medium, to provide heat, the air in heating, drying workshop, by wind-force, make hot-air convection, in order to heat wet vermicelli, take away the moisture in wet vermicelli simultaneously, reach dry object.Directly emptying due to waste gas in dry run, has not only taken away waste heat, causes waste, and the thermal efficiency is lower, and has polluted environment, and waste heat is not used, and energy loss is very large.
Heat pump is energy-efficient so that himself was had, cost is lower and the feature such as free from environmental pollution, has been used in vermicelli drying course.But, there is following defect in the heat pump assembly that is applied at present noodle drying process: because laid heat pipe is done as a whole, whole hothouse through vermicelli, so in the three phases (preliminary drying, main baking, tempering) that vermicelli are dried, the temperature of drying medium is almost constant, the dry subregion of vermicelli is not obvious, makes vermicelli in almost identical dry run, the difficult quality guarantee of vermicelli.In addition, be directly discharged to the central waste gas of environment and contain a large amount of waste heats, caused unnecessary energy loss.
Summary of the invention
Object of the present invention combines heat pump air conditioner technology and noodle drying process exactly, will after the thermal energy collecting of air, be used, and the temperature of circulated air in dry run, humidity and circular flow accurately and are effectively controlled; When improving the effect and quality of vermicelli oven dry, eliminate the pollution of waste gas and noise, improved working environment, further save the energy.
The technical solution adopted for the present invention to solve the technical problems is: a kind of noodle drying process heat recovery heat pump air conditioning system, it comprises compressor, condenser, evaporimeter, blower fan, expansion valve and heat exchanger etc.According to each section of principle that temperature requirement is different in vermicelli drying course, design three cover high temperature heat pump systems.Between drying vehicle, place three condensers, the requirement according to vermicelli to three sections of temperature, designs different condensation temperatures, thereby obtains suitable wind pushing temperature.For the air draft between drying vehicle, because temperature is high, high humidity, enthalpy be high, has very large waste heat, by airduct, air draft is collected and is sent to evaporimeter.Evaporimeter is formed in parallel by the evaporimeter of three cover high temperature heat pump systems, and air draft is in the process process of evaporimeter, and temperature reduces, and discharges a large amount of heats of condensation, by evaporimeter, is absorbed.Compressor is connected with the Fin-tube Condenser being placed between vermicelli drying vehicle by pipeline, then this condenser is connected with the evaporimeter outside job shop through expansion valve, evaporimeter is communicated with compressor, and the refrigerant tubing going out by bypass between evaporimeter and plate-type evaporator is connected.From bypass between compressor and evaporimeter, go out other two cover plate-type evaporators, reduce the temperature of cold-producing medium, when summer, to packing shop and office, provide cold.Native system reclaims the used heat between vermicelli drying vehicle, for heat is provided between drying vehicle, simultaneously in summer, provides cold for other rooms.The original steam generator system with conduction oil heat supply has been replaced to the high temperature heat pump system with condenser heat supply, made full use of face factory used heat, improved working environment, further reached the target of saving the energy, consumption reduction reduction of discharging.

The specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As this noodle drying process heat recovery heat pump air conditioning system of Fig. 1, by three cover high temperature heat pump systems, formed: first compressor (4) of the first cyclic high-temperature heat pump is connected with the first Fin-tube Condenser (1) being placed between vermicelli drying vehicle by pipeline, then this condenser (1) is connected with the first evaporimeter (14) outside job shop through the first expansion valve (7), and the first evaporimeter (14) is communicated with the first compressor (4) by pipeline; Second compressor (6) of the second cyclic high-temperature heat pump is connected with the second Fin-tube Condenser (2) being placed between vermicelli drying vehicle by pipeline, then this condenser (2) is connected with the second evaporimeter (16) outside job shop through the second expansion valve (9), and the second evaporimeter (16) is communicated with the second compressor (6) by pipeline; The 3rd compressor (5) of the 3rd cyclic high-temperature heat pump is connected with the 3rd Fin-tube Condenser (3) being placed between vermicelli drying vehicle by pipeline, then this condenser (3) is connected with the 3rd evaporimeter (15) outside job shop through the 3rd expansion valve (8), and the 3rd evaporimeter (15) is communicated with the 3rd compressor (5) by pipeline.
