Description
Technical field
The present invention relates to a kind of dry air intake generation device of dryer, belong to dryer technical field.
Background technology
Dryer is also drying equipment or drying machine, and surrounding air is heated to proper temperature by hot-blast stove by existing dryer usually, and the air after heating is transported to drying chamber, carries out dehumidification treatments to needing dry article (as grain etc.).
But in high temperature damp-heat area (such as Hainan etc.), the humidity of surrounding air is very large, surrounding air is delivered directly to the poor effect that drying chamber dehumidifies to article, and hot-blast stove often adopts fuel oil, firewood or other combustible materials etc. to produce power, the energy consumed is more, not only add the production cost of dryer, and pollute environment.In addition, the life-span of hot-blast stove only has 2 ~ 3 years, but selling price remains high always, therefore also needs cheap replacement scheme badly.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of can improve the drying efficiency of dryer and cost is lower, energy-conserving and environment-protective produce the device of dry wind for dryer.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of dry air intake generation device of dryer, comprise compressor, intake stack and be successively set on evaporimeter in intake stack and condenser along intake stack airflow direction, described compressor respectively with the refrigerant exit of evaporimeter and the refrigerant inlet communication of condenser, the refrigerant import of described evaporimeter is communicated with the refrigerant exit of condenser, is provided with expansion valve between the refrigerant import of described evaporimeter and the refrigerant exit of condenser; Described intake stack forms air outlet near one end of condenser and is communicated with dryer air inlet; Described intake stack forms near the other end of evaporimeter the air inlet being communicated with surrounding air; Intake stack lateral wall between described evaporimeter and condenser is glued with heat absorbing sheet, and also including can by natural wind or the hot blast drainage blower fan through heat absorbing sheet.
The dry air intake generation device of dryer of the present invention will create a condition in fact exactly, allows the air of the low relative humidity with proper temperature flow through article to be dried, and to take away moisture fast, its course of work is as follows:
1) under the main air blower effect of dryer, surrounding air enters intake stack, absorbs heat cooling, the portion of water condensation in air is separated out the air obtaining low temperature low relative humidity by evaporimeter;
2) air of the low relative humidity of low temperature recovers room temperature under the effect of heat absorbing sheet and blower fan, obtains the low relative humidity air of room temperature;
3) compressor exchange heat that evaporimeter is absorbed is to condenser, and the low relative humidity air of room temperature heats under the effect of condenser, becomes dry high temperature air and is transported in dryer.
The beneficial effect that the present invention brings is:
1) the present invention utilizes evaporimeter, condenser and compressor to carry out heat exchange, not only can by surrounding air cool-down dehumidification, and dehumidification rate is very high, compares the energy consumption that additive method considerably reduces dehumidifying; In addition, the heat utilizing condenser to be obtained by cool-down dehumidification fully utilizes, and is not only conducive to the drying efficiency improving dryer, and reduces the energy consumption needed for atmosphere temperature rising, heat environmental protection more relative to hot-blast stove, be particularly suitable for the area of high-temperature high-humidity.
2) surrounding air after cool-down dehumidification is creatively returned to room temperature rapidly by heat absorbing sheet and blower fan by the present invention, thus utilize the high heat exchanger effectiveness of compressor to obtain the low humidity air of high temperature, and required energy consumption is only the power consumption driving compressor and blower fan.If the present invention saves heat absorbing sheet and blower fan, then only can obtain the low humidity air of room temperature.In addition, with traditional hot-blast stove heat only can obtain high temperature surrounding air compared with, the present invention can not only obtain dry high temperature air, and Energy Efficiency Ratio improves greatly.
In order to prevent the moisture by condensation from surrounding air is separated out to be brought in dryer under the effect of air-flow, the present invention arranges water leg immediately below evaporimeter.In addition, under the effect of air-flow, can form negative pressuren zone in water leg, therefore the present invention arranges the air inversion at the water leg discharge outlet place that draining pump can prevent negative pressure from causing in water leg.
In order to prevent the moisture by condensation from surrounding air is separated out to be brought in dryer under the effect of air-flow further, the present invention can adopt one of following three kinds of technical schemes:
(1) described intake stack is vertically arranged, and described evaporimeter is positioned at immediately below condenser, and the air inlet of described intake stack is arranged on the side of intake stack.
(2) described intake stack is horizontally disposed with, and is provided with ventilative water bar in the intake stack between described evaporimeter and heat absorbing sheet, and described baffle plate is evaporated in air for preventing from the moisture in water leg to be taken in condenser heating again.
Preferably, described water bar is positioned at water leg directly over the cell wall of condenser side.
(3) described intake stack is divided into three sections, and be respectively the first pipeline, second pipe and the 3rd pipeline, wherein the first pipeline is vertically arranged, and described evaporimeter is placed in the first pipeline; Second pipe is horizontally disposed with, and described condenser and heat absorbing sheet are arranged on the inner side and outer side of second pipe respectively; 3rd pipeline is positioned at the below of second pipe, the 3rd pipeline respectively with the outlet of the first pipeline and the inlet communication of second pipe, described water leg is positioned at the inside bottom of the 3rd pipeline.As improving further, the air outlet of described first pipeline is lower than the bottom of second pipe.
In order to strengthen the heating effect of heat absorbing sheet to Cryogenic air further, the present invention can also increase exhaust duct, one end of described exhaust duct is communicated with the exhaust outlet of described dryer, the hot blast drainage that the exhaust outlet of dryer is discharged by the other end of described exhaust duct through heat absorbing sheet, the wind direction that described exhaust duct produces and the wind direction that blower fan produces basically identical.
The weather seasoned oneself to cold better to make the present invention, arranges the hot-blast stove being used for air in auxiliary heating intake stack between described condenser and the air outlet of intake stack.Compared with traditional only use hot-blast stove mode of heating, the present invention is economize energy more, and what obtain is the air that the air of high temperature drying instead of humidity are larger.
