Description
Technical field
The utility model relates to a kind of tunnel passage type drying device, belongs to using energy source and field of energy-saving technology.
Background technology
The tunnel passage type drying device adopts the pneumatic conveying drying mode, is usually used in dry natural rubber, tealeaves, melon and fruit, vegetables, medicinal material, grain etc., is a kind of drying device commonly used.Present tunnel passage type drying device, temperature and humidity for exhaust emissions is not controlled basically, for the design of the flow and the air circulation of exhaust emissions, mainly consider to make that the hot blast that flows through material has certain flow velocity, so that promote mass transfer and heat transfer between thermal current and the material.Given this, for for the purpose of holding, often select the blower fan of big flow, and the flow of blower fan is unadjustable in the design.So, cause that the tail gas exhaust air rate is bigger than normal, exhaust steam moisture is on the low side, meaningless consumption a large amount of energy, reduced rate of energy.In addition,, also strengthened the power consumption of blower fan, caused power consumption higher because the blower fan model is bigger than normal.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and providing a kind of can significantly cut down the consumption of energy, and improves the tunnel passage type drying device of energy utilization rate.
The technical solution of the utility model is: comprise compositions such as tunnel passage type drying cupboard, hot air circulation blower, hot air circulation airduct, storage heater, hot blast heating-up temperature sensor, fresh inlet, material carrying device, tail gas exhaust blower, tail gas exhaust duct, controller, it is characterized in that humidity sensor being set at the tail gas exhaust duct, the tail gas backwind tube is set to the tunnel passage type drying cupboard at the tail gas exhaust blower port of export, the tail gas blast pipe is set to the drying cupboard feed end.
At exhaust pipe and tail gas backwind tube control valve is set respectively, variable-frequency governor is set respectively at tail gas exhaust blower and hot air circulation blower.The material carrying device enters from an end of tunnel passage type drying cupboard (calling drying cupboard in the following text), and heat transfer, effect of mass transmitting by thermal current in drying cupboard are finished dry run, and the other end of self-desiccation cabinet is released.The purpose of this dry device is with less power consumption and thermal energy consumption, keeps air-flow distribution, Temperature Distribution and moisture distribution suitable in the drying cupboard.System is in service, by the rotating speed that the control valve and the variable-frequency governor of adjusting tail gas exhaust duct are regulated the tail gas exhaust blower, the capacity of control tail gas, the humidity of tail gas is controlled in certain scope, be tail gas humidity hour, reduce the capacity of tail gas, otherwise increase the capacity of tail gas; By the rotating speed that the control valve and the variable-frequency governor of adjusting tail gas backwind tube are regulated air exhauster, the air circulation of control tail gas; By the temperature sensor monitors return air temperature, adopt variable-frequency governor, by regulating the rotational speed regulation air circulation of hot air circulation blower, return air temperature is remained in the suitable scope.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment.
Embodiment be one be used for natural rubber the tunnel passage type drying device, by known tunnel passage type drying cupboard 9, hot air circulation blower 6,12, hot air circulation airduct 4,14, storage heater 5,13, hot blast heating-up temperature sensor 8,11, fresh inlet 16, material carrying device 18, tail gas exhaust blower 1, tail gas exhaust duct 24, controller 21 compositions such as grade, at the tail gas exhaust duct temperature sensor 26 is set in addition, humidity sensor 27, the place is provided with temperature sensor 3 at the hot air circulation return air inlet, 15, tail gas backwind tube 23 is set to drying cupboard at the tail gas exhaust blower port of export, at exhaust pipe and tail gas backwind tube control valve 25 is set respectively, 22, at tail gas exhaust blower and hot air circulation blower variable-frequency governor 2 is set respectively, 7,11.The material carrying device is a materials vehicle 18 in the present embodiment, and track 17 is set matches with it, the exhaust emissions end that materials vehicle loads natural rubber self-desiccation cabinet enters, heat transfer, effect of mass transmitting by thermal current in drying cupboard are finished dry run, and the other end of self-desiccation cabinet (fresh inlet end) is released.The formation of this dry device, its purpose are with less power consumption and thermal energy consumption, keep air-flow distribution, Temperature Distribution and moisture distribution suitable in the drying cupboard, and its operating parameter can be regulated as required and control.
System is in service, and the tail gas of discharge is taken away a large amount of heats, thereby the capacity of control tail gas and the controlled factor that exhaust steam moisture is the system energy consumption index.Theoretically, capacity is more little, and energy resource consumption is low more, and the relative humidity that its least limit capacity is a tail gas reaches 100%.Among the embodiment relative humidity of tail gas is controlled in 70%~85% scope.By the control valve 25 of adjusting tail gas exhaust duct and the rotating speed of variable-frequency governor 2 adjusting tail gas exhaust blowers 1, the capacity of control tail gas is controlled at the humidity of tail gas in the scope of setting, and promptly tail gas humidity hour, reduce the capacity of tail gas, otherwise increase the capacity of tail gas.
Capacity by control tail gas, making the drying cupboard afterbody pass material bed hot air flow reduces, be unfavorable for hot blast and material bed between heat and mass, therefore tail gas backwind tube 23 and control valve 22 thereof are set, make its part tail gas reuse, pass material bed hot air flow so that strengthen the drying cupboard afterbody, promote hot blast and material bed between heat and mass.
Temperature sensor 26 is set, in order to the delivery temperature of monitoring tail gas, for the operation of regulating and control drying device provides reference on the tail gas exhaust duct.
Be provided with two groups of storage heaters 5,13 among the embodiment at the middle part of drying cupboard.Its objective is and in drying cupboard, import heat, promote gas to pass material bed flowing simultaneously, promote its heat and mass.Therefore, air circulation reaches as above that two purposes get final product, and excessively increases its power consumption then meaninglessly.Temperature sensor 8,10 monitoring heating-up temperatures are set, in 110 ℃~120 ℃ scopes, too high or too low for temperature heating and temperature control, regulate by electrically heated input power; Temperature sensor 3,15 monitoring return air temperatures are set, return air temperature is controlled in 90 ℃~100 ℃ scopes, and temperature is low excessively, can increase rotation speed of fan by variable-frequency governor 7,11, otherwise the reduction rotation speed of fan, but minimum can not the making of rotation speed of fan passed material bed hot blast flow velocity and is lower than 1.5m/s.
Among the embodiment, fresh air enters and passes material bed from the discharging one end air inlet 16 of drying cupboard, on the one hand material is cooled off, and is convenient to subsequent packages; On the other hand heat is reclaimed the new wind of preheating, help energy-conservation.New wind enters and is divided into two parts, and a part of inner passage by drying cupboard enters one group of hot air circulation heating system and heats; Another part enters another group hot air circulation heating system by fresh wind tube 20 and heats.Control valve is set on fresh wind tube, is used to regulate the ratio of the new wind of two parts.
The material carrying device is " car-track " carrying mode in the present embodiment, can be used for " chain-sprocket wheel " carrying mode in addition.
