Description
Technical field
The utility model is related to drying technology field, more particularly to a kind of vermicelli drying equipment.
Background technology
Currently known vermicelli drying equipment mainly provides thermal source, fuel combustion using coal, natural gas as fuel（Especially
Coal）The flue dust of generation pollutes environment rich in pollutants such as a large amount of carbon monoxide, carbon dioxide.As country puts into effect various relevant
Prohibit the policy of combustion, fuel type drying equipment will be banned gradually, and the heat pump drying technology of more energy-conserving and environment-protective progresses into vermicelli
The field of drying.
At present, vermicelli heat pump drying uses air source heat pump, and it sends into heat in barn, and humidity discharging wind is directly with useless
The form discharge of gas, or simple backheat utilization is carried out, Waste Heat Reuse rate is very low, and this results in the waste of mass energy, and
When environment temperature is relatively low, air source heat pump is influenceed than larger by environment temperature, and Energy Efficiency Ratio is relatively low, is unfavorable for national big face
Product application.
It is well known that heat pump drying equipment is a kind of special equipment of dry materials, heat pump provides heat for drying equipment
Supply, the air of high temperature drying takes away the steam in material, so as to reach dry purpose.As high temperature gas flow is constantly taken away
Steam, the gradually reduction of the temperature of air-flow, humidity increase, the water separation capability to material is gradually reduced；Therefore, when airflow humidity reaches
Need to discharge the Hot wet air heating in a part of baking room after to setting humidity target, the dry air being introduced into environment proceeds
Dehydrate process.Current heat-pump apparatus is limited by heat pump feature, and heat pump heating capacity and Energy Efficiency Ratio are equal in compared with low ambient temperature

Degree influence, is required to that operation is dried throughout the year, so when matching heat pump, it is often necessary to according under low ambient temperature
Thermic load is matched, and now heat-pump apparatus apolegamy can be very big, so not only adds the initial outlay of drying equipment, Er Qie
The Energy Efficiency Ratio of heat pump drying equipment is relatively low under low ambient temperature, and power savings advantages significantly weaken, and when environment temperature is higher, heat
The utilization rate of pumping unit is very low.
Currently known pump type heat vermicelli drying device simple in construction, more with heat pump heat exchanger（Condenser）Directly heat
Air in barn is used as absorption thermal source, i.e., so-called surrounding air as dried medium using heat pump main frame ambient air
Source heat pump.Even if the backheat for having humidity discharging wind is utilized, it is also to guide humidity discharging wind near heat pump main frame, carries out the evaporator of heat pump
Single-stage disposable thermal is exchanged, and reclaims heat very limited.Moreover, waste-gas heat is reclaimed using single-stage evaporator, when the temperature of waste gas
When higher, only by the cooling of flush distillation device, latent heat is difficult to be recovered in humid air, and most of heat is discharged, and is still made
Into heat waste.
Utility model content
The purpose of this utility model is to provide a kind of pump type heat vermicelli drying device simple in construction, and structure is relatively simple
With it is compact, be adapted to grassroot project and the transformation of old barn, cost is relatively low, and Energy Efficiency Ratio is higher.
To achieve the above object, a kind of heat pump noodle drying device utilized with backheat of the present utility model is including roasting
Room, vaporization chamber and heat pump, it is characterised in that：The vermicelli pipeline for being used for hanging and convey vermicelli is provided with inside barn, is hung

Pipe.
Inwall of the peripheral outer wall of each evaporator with vaporization chamber connects into closed cavity.
The utility model has the following advantages：
In the utility model, the evaporator spacing side by side of multilevel heat pump system is arranged in vaporization chamber, so as to be arranged in series
In on the wind path of hot blast, under barn drying system steady-working state, make the humidity discharging wind in humidity discharging air channel step by step by different levels
Evaporator, so that the temperature of reduction moisture regain wind step by step, allows to cool to saturation state and condense into water, humidity discharging wind realizes that low temperature is arranged
Put.The sensible heat and vapour latent heat in humidity discharging wind are absorbed to greatest extent by evaporator with heat pump in the process.Meanwhile, by
Stablize relatively in the humiture of humidity discharging wind, do not influenceed by external environment Four seasons change, improve the COP of heat pump, it is ensured that
Heat pump efficient stable works, and realizes the efficient backheat utilization of drying system, the work of heat pump efficient stable, saves the energy, protect
Retaining ring border.
When vermicelli barn drying system just brings into operation, there is no hydrofuge wind now, heat pump can only be by absorbing its week
The heat for enclosing surrounding air is started, and carries out barn heating preheating.But, if always according to heat pump multi-stage evaporator wind path
Tandem working, it will form evaporimeter frosting --- air quantity reduction --- heat pump system efficiency decline --- frosting again --- air quantity
Reduce again --- in the vicious circle that efficiency declines again, until heat pump can not work.
The utility model employs the method set up and start blower fan and air-valve, is equipped with conjunction to break above-mentioned vicious circle
The electrical control program of reason, can make heat pump complete the startup task of vermicelli barn drying system well.In barn temperature
When degree rises to sets target value, wet vermicelli start into room, and when reaching setting position, vermicelli barn drying system opens row
Wet, then heat pump is automatically stopped start-up mode, while being transferred to normal drying mode.
The start-up mode of heat pump is as follows：After start, whole air-valves are first turned on, are then turned on starting blower fan, air draft
Blower fan and heat pump, surrounding air enter evaporator room along air-valve, distinguish under the driving of blower fan only after one-level evaporator
Discharge, for wind path, evaporator is in parallel connection, improves the operating mode of evaporator, and it is too low to prevent evaporating temperature, makes heat
Pumping system smoothly completes startup work.
Current heat-pump apparatus is limited by heat pump feature, and heat pump heating capacity and Energy Efficiency Ratio compare in compared with low ambient temperature
It is low, it is limited in cold district（Such as the Northeast of China）Application.The utility model uses ring only in initial start
The higher hydrofuge wind of temperature in use, therefore when normally running, environment temperature is to this practicality always in border gas, normal course of operation
The operational efficiency influence very little of new middle heat pump, makes the utility model be provided with widely compared to normal heat pump
Adaptability, can still keep higher Energy Efficiency Ratio, with extensive environmental suitability in more cold area.
Heat pump mode of heating of the present utility model is more direct, and structure is simpler, the bar met in barn locus
It is applicable very much under part, be particularly suitable for use in grassroot project.
