Description
Technical field
The present invention relates to a kind of heat-accumulation type hot wind generation apparatus suitable for hot-wind nonwoven cloth, especially by society's electricity consumption amount
The fuse salt at moment at a low ebb is electrically heated accumulation of heat, and the heat of storage is carried out the baking of non-woven fabrics forming machine by the peak of power consumption moment
Dry heating.The invention belongs to the technical fields of textile industry drying process.
Background technology
Non-woven fabrics be made of a certain amount of orientation or random fiber, have easily decompose, it is cheap, it is nontoxic can
The features such as regeneration is the environment-friendly materials of a new generation.Hot-wind nonwoven cloth is under the jurisdiction of one kind in hot blast adhesion non-woven fabrics, hot wind nonwoven
It is to penetrate fibre web using the hot wind on drying plant after fiber is combed into, is allowed to heated and is able to the non-woven fabrics that bonding generates.
Wherein, hot blast adhesion, which refers to, penetrates fibre web using hot wind on drying plant and is allowed to melted by heating and the mode of production that generates bonding.
Currently, the heat source of hot wind is all made of direct electro heating, the proportion that electricity cost accounts for nonwoven production cost is higher.Therefore, such as
What, which reduces drying cost, becomes urgent problem.
On the other hand, to encourage user rationally to shift power load, peak load shifting, the electricity consumption for reducing peak interval of time is born for country
Lotus rate improves the utilization ratio of system installed capacity and energy saving, implementation Peak-valley TOU power price.To Electricity customers, when peak
The few electricity consumption of section, low-valley interval Multifunctional electric, advantageously reduce electric cost；To power grid enterprises, the cost of investment of power grid can be reduced
And operating cost, ensure the safe and stable operation of power grid；To electricity power enterprise, can reduce due to peak regulation and increased peak regulation cost
Expense；To society, Electricity Investment is advantageously reduced or delayed, promotes the reasonable disposition of social resources.
Consider the demand of the non-woven fabrics performance of enterprises and national peak load shifting, the present invention proposes a kind of suitable for heat
The heat-accumulation type hot wind generation apparatus of wind non-woven fabrics, electric energy storage when using high-temperature fusion salt as heat storage medium by low ebb, reduces
Enterprise's production cost.
Invention content
The object of the present invention is to provide a kind of heat-accumulation type hot wind generation apparatus suitable for hot-wind nonwoven cloth, to reduce heat
The production cost of wind non-woven fabrics.To achieve the above object, the present invention provides a kind of drying unit, which specifically includes electricity and adds
Hot device switch board, fused salt tank, baking oven, salt pump, finned heat exchanger.In the heat-accumulation type hot wind generation apparatus, in fused salt tank
Equipped with a certain amount of fuse salt, when society's electricity consumption amount is in trough, electric heater works as society's electricity consumption to fuse salt heat storage
High-temperature fusion salt is exported by salt pump when amount is in wave crest.Cheap trough electricity price is made full use of to reduce hot-wind nonwoven cloth
Production cost.In the heat-accumulation type hot wind generation apparatus, by the finned heat exchanger completion high-temperature fusion salt and often
The heat exchange of warm air, normal temperature air are thermally formed hot wind, and hot wind enters baking oven by unshaped non-woven fabrics fiber heating, drying
Generate non-woven fabrics finished product.In the heat-accumulation type hot wind generation apparatus, there are two sets of drying units, unshaped nonwovens in baking oven
Measuring fiber enters baking oven, as unshaped non-woven fabrics fiber advances, successively passes through two sets of drying units, and humidity is smaller and smaller,
Temperature is higher and higher, and non-woven fabrics finished product is generated until being oven-dried to export out from baking oven.Simultaneously waste heat wind in this process by
Two sets of drying units recycle, and make full use of thermal energy, and the peak load shifting for realizing electric energy utilizes, and reduces the life of hot-wind nonwoven cloth
Produce cost.
The present invention has the following advantages compared with prior art：
The cheap characteristic of electricity price, reduces the production cost of hot-wind nonwoven cloth when society's electricity consumption 1, being made full use of to be in trough；
2, there are two sets of drying systems in the heat-accumulation type hot wind generation apparatus, rational to arrange that air port keeps oven temperature equal
It is even, to improve the quality and yield of non-woven fabrics.

Specific implementation mode
Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, being equipped with a certain amount of fuse salt, when society's electricity consumption amount is in trough, electric heater in fused salt tank 4
Switch board 1 is exported when society's electricity consumption amount is in wave crest by salt pump 5 by controlling electric heating tube 3 to fuse salt heat storage
High-temperature fusion salt enters finned heat exchanger 9.Temperature sensor 2 detects the temperature in fused salt tank 4, when temperature is less than in fused salt tank
At 150 DEG C, electric heater switch board 1 controls electric heating tube 3 and is begun to warm up to fuse salt, when temperature is higher than 430 DEG C in fused salt tank
When, electric heater switch board 1, which controls electric heating tube 3 and heated to fuse salt, to be stopped.The fuse salt of 4 high temperature of fused salt tank passes through salt pump
5 enter the pipe side of finned heat exchanger 9, and the wherein rotating speed of salt pump 5 is controlled by motor 6 and frequency converter 7, and air is in air blower 10
Lower entrance 9 shell-side of finned heat exchanger is blown, air generates hot wind, hot wind with the heat exchange of high-temperature fusion salt in finned heat exchanger 9
Into in baking oven 11, on roller bearing 12 unshaped non-woven fabrics fiber be oven-dried when by baking oven 11 generate non-woven fabrics at
