Abstract
The utility model discloses a double-fan circulating ventilator of a drying system. The double-fan circulating ventilator comprises a drying room and a corresponding control system, wherein a box body is arranged in the drying room; a heat exchanger is arranged in the box body; the box body is provided with an air flue outlet and an air flue inlet respectively; at least one vertical circulating fan is arranged in the box body, and the air outlet of the fan corresponds to the air flue outlet; at least one horizontal circulating fan is arranged outside the box body; and an air distribution system is arranged at the bottom of the drying room and above the air flue outlet. According to different dried articles and different drying degrees, the two circulating fans can be simultaneously started, and a circulating direction can also be separately used. A ventilating passage for air distribution is arranged below the dried material in the vertical ventilating mode, so that the horizontal flowing air is converted into vertical upward airflow, and uniform air distribution is realized.
Description
Technical field:
The utility model relates to dry field, is specifically related to a kind of two wind circulating ventilation structures of drying system.
Background technology:
At present, social in modern times, the energy consumption of drying operation is higher, and according to incompletely statistics, 14% of developed country's industrial energy consumption is used for drying, and the 20%-25% of Denmark and German institute consumes energy is used for drying.In China, drying operation also is one of big power consumer, and its energy consumption accounts for about 12% of national economy total energy consumption.In dry run, parameters such as Uniform Ventilation property and heat exchange area to drying after the quality of target item, significant impact is all arranged drying time and power consumption etc.Usually the horizontal drying system in side that adopts, because of drying shed length is big, dry goods thickness is bigger on the contrast air current flow direction; Thereby make that the part objects heat exchange is bad, it is inhomogeneous to ventilate, for the requirement that reaches dry moisture has to prolong drying time; Not only strengthened energy consumption; And uneven drying is even, and the article quality that is dried reduces, and economic effect is poor.
This shows that this ventilating system has is energy-conservation, save operating cost, promote the effect of the quality of the back article that are dried, and promotes the competitiveness of the article that are dried, and helps the economical and energy saving target of dry industry.
The utility model content:
The purpose of the utility model provides a kind of two wind circulating ventilations of drying system; Through two with fan; Generation level and vertical two circulation wind fields in drying shed; Thereby increase the contact area of dry goods and thermal current, improve dry uniformity, reach the drying quality that energy-conservation, economic purpose also improves the article that are dried.
The utility model is achieved through following technical scheme: two wind circulating ventilations of drying system comprise drying shed; And corresponding control system, establish casing in the said drying shed, establish heat exchanger in the said casing; Establish ducting outlet and air channel import on the casing respectively; Establish at least one vertical circulation blower fan in the said casing, the air outlet of said blower fan is corresponding with ducting outlet, at least one horizontal cyclic blower fan of said casing peripheral hardware; Said cloth wind system places the drying shed bottom, and is located at the ducting outlet top.
At least one blower fan circulated air of deriving wherein, when drying shed inner drying article, wind direction is vertical with horizontal plane, and at least one blower fan is when dry goods in addition, and wind direction is parallel with horizontal plane;
Said cloth wind system adopts modes such as orifice plate or plate seam to be tiled in the drying shed bottom, vertical circulation wind from then on below orifice plate or the plate seam upwards evenly blowing form the wind direction vertical with horizontal plane, thereby dry goods;
Whole box body is airtight, only on casing, leaves air channel import and ducting outlet, and remainder adopts sealing means;
In the said casing heat exchanger is arranged, there is the flow of hot water mistake heat exchanger inside, through blower fan air inducing, thereby and flow through that heat exchanger is outside to be produced heat exchange and add hot-air, carry out the article drying at last;
Said control system is connected with vertical circulation blower fan and horizontal cyclic blower fan respectively, can control the blower fan of both direction, and carries out folding as required separately and close;
The utility model is different different with degree of drying according to dry goods, and two circulations can start simultaneously, also can use a kind of loop direction separately.Wherein the vertical ventilation mode is employed in and vent passages is set below the dried material and carries out cloth wind, makes the bottom horizontal flow sheet air change air-flow vertically upward into, realizes even distributing wind.

The specific embodiment:
Below be to the further specifying of the utility model, rather than to the restriction of the utility model.
Embodiment 1:
The utility model like Fig. 1, shown in Figure 2, two wind circulating ventilations of drying system comprise drying shed 3, and corresponding control system; Establish casing 6 in the drying shed 3, establish heat exchanger 7 in the casing 6, establish ducting outlet 5 and air channel import 8 on the casing 6 respectively; Establish at least one vertical circulation blower fan 2 in the casing 6, the air outlet of blower fan 2 is corresponding with ducting outlet 5, at least one horizontal cyclic blower fan 1 of casing 6 peripheral hardwares; Cloth wind system 4 places drying shed 3 bottoms, and in practical project, drying shed 3 highly is 2000mm; Cloth wind system 4 is apart from bottom surface 300mm place, and cloth wind system 4 is general to adopt orifice plates, plate seam etc., and is located at ducting outlet 5 tops.
The course of work of the utility model is following:
Drying shed 3 outer hot water get into heat exchanger 7 through hot water inlet and outlet piping 9, and the heat exchanger 7 of flowing through, and at least one vertical circulation blower fan 2 is in casing 6; Recirculating air flow is heated through heat exchanger 7, and casing 6 is airtight only to have the air channel to import and export (5,8), and remainder adopts sealing; The thermal current that flows out from the ducting outlet of casing 65 is behind the cloth wind system 4 of the bottom of drying shed 3; Thermal current is converted into the direction air-flow vertical with horizontal plane, and article carry out drying thereby heating is dried, and the moisture absorption heat of vaporization in the article that are dried gets into thermal current; Thermal current gets into casing 6 from the air channel import 8 of casing 6, reheats and circulates;
Simultaneously at least one horizontal cyclic blower fan 1 is arranged, form the circulation flow field of horizontal direction, mix, strengthen the contact area of dry goods and hot-air with the flow field of vertical direction in casing 6 outsides, simultaneously that thermal current is more even.
Simultaneously, different according to dry progress with type of goods, can control independent usage level circulating fan 1 of folding or vertical circulation blower fan 2 and startup simultaneously.
