Description
Technical field
The dry air intake generation device that the present invention relates to a kind of dryer, belongs to dryer technical field.
Background technology
Dryer is also drying equipment or drying machine, and existing dryer is heated to proper temperature by hot-blast stove by surrounding air conventionally, and the air after heating is transported to drying chamber, and the dry article of needs (as grain etc.) are carried out to dehumidification treatments.
But such as, in high temperature damp-heat area (Hainan etc.), the humidity of surrounding air is very large, surrounding air is delivered directly to the poor effect of drying chamber to article dehumidifying, and hot-blast stove often adopts fuel oil, firewood or other combustible materials etc. to produce power, the energy consuming is more, not only increase the production cost of dryer, and polluted environment.In addition, the life-span of hot-blast stove only has 2 ~ 3 years, but selling price is always high, 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 that the technical scheme that solves the problems of the technologies described above proposition is: a kind of dry air intake generation device of dryer, comprise compressor, intake stack and be successively set on evaporimeter and the condenser in intake stack along intake stack airflow direction, described compressor is communicated with the refrigerant exit of evaporimeter and the refrigerant import of condenser respectively, the refrigerant import of described evaporimeter is communicated with the refrigerant exit of condenser, between the refrigerant import of described evaporimeter and the refrigerant exit of condenser, is provided with expansion valve; Described intake stack forms air port 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 that is communicated with surrounding air; Intake stack lateral wall between described evaporimeter and condenser is glued with heat absorbing sheet, and also including can be by the blower fan of natural wind or hot blast drainage process heat absorbing sheet.
The dry air intake generation device of dryer of the present invention will be created a condition in fact exactly, allows the air stream of the low relative humidity with proper temperature through article to be dried, and to take away fast moisture, its course of work is as follows:
1) under the main air blower effect of dryer, surrounding air enters intake stack, absorbs heat cooling by evaporimeter, and airborne part moisture condensation is separated out to the air that obtains low temperature low relative humidity;
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) exchange heat that compressor absorbs evaporimeter 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 be by surrounding air cool-down dehumidification, and dehumidification rate is very high, compare additive method and significantly reduced the energy consumption of dehumidifying; In addition, utilize the heat that condenser obtains cool-down dehumidification fully to utilize, be not only conducive to improve the drying efficiency of dryer, and reduced the energy consumption required to atmosphere temperature rising, heat environmental protection more with respect to hot-blast stove, be particularly suitable for the area of hot and humid degree.
2) the present invention creatively returns to rapidly room temperature by the surrounding air after cool-down dehumidification by heat absorbing sheet and blower fan, thereby the high heat exchanger effectiveness that utilizes compressor obtains the low humidity air of high temperature, and required energy consumption is only the power consumption of drive compression machine and blower fan.If the present invention saves heat absorbing sheet and blower fan, only can obtain the low humidity air of room temperature.In addition, compared with the surrounding air that only can obtain high temperature with the heating of traditional hot-blast stove, the present invention not only can obtain dry high temperature air, and Energy Efficiency Ratio improves greatly.
For the moisture that prevents condensation from surrounding air to separate out is brought in dryer under the effect of air-flow, the present invention arranges water leg under evaporimeter.In addition, under the effect of air-flow, can form negative pressuren zone in water leg, therefore the present invention arranges draining pump and can prevent the air inversion at the water leg discharge outlet place that negative pressure causes in water leg.
For the moisture that further prevents condensation from surrounding air to separate out is brought in dryer under the effect of air-flow, the present invention can adopt one of following three kinds of technical schemes:
(1) described intake stack vertically arranges, described evaporimeter be positioned at condenser under, 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 for preventing that moisture in water leg is taken to condenser heating and is evaporated in air again.
As preferred version, described water bar is positioned at directly over the cell wall of water leg near condenser one side.
(3) described intake stack is divided into three sections, is respectively the first pipeline, second pipe and the 3rd pipeline, and wherein the first pipeline vertically arranges, 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 respectively inner side and the outside of second pipe; The 3rd pipeline is positioned at the below of second pipe, and the 3rd pipeline is communicated with the outlet of the first pipeline and the import of second pipe respectively, and described water leg is positioned at the inside bottom of the 3rd pipeline.As improving further, the air outlet of described the first pipeline is lower than the bottom of second pipe.
In order further to strengthen the heating effect of heat absorbing sheet to Cryogenic air, 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 other end of described exhaust duct is discharged the exhaust outlet of dryer is through heat absorbing sheet, and the wind direction that the wind direction that described exhaust duct produces and blower fan produce is basically identical.
For the weather that the present invention is seasoned oneself to cold better, between described condenser and the air outlet of intake stack, be provided for the hot-blast stove of air in auxiliary heating intake stack.Compared with traditional only use hot-blast stove mode of heating, the present invention more saves the energy, and what obtain is air rather than the larger air of humidity of high temperature drying.
