Abstract
Pig house heat exchange open air exhaust device is closed in a kind of high and cold area, belongs to agricultural technology field.The purpose of this utility model is to provide a kind of without peripheral hardware firing equipment, closes pig house heat exchange open air exhaust device at cold snap by heat exchange to the high and cold area passing into warm braw in pig house.The utility model is that indoor wind discharges case in the upper end of device, and lower end is that outdoor wind enters case, and indoor wind discharges case the outlet communicated with the external world, and outdoor wind enters case the air intake vent communicated with indoor; The negative and positive dividing plate being provided with positive passage and cloudy passage composition in heat-exchanging chamber that case and indoor wind discharges between case is entered at the outdoor wind of device, not connected between sun passage and cloudy passage, sun passage has to discharge the indoor wind that case communicates and exports with indoor wind, cloudy passage has the outdoor wind entrance entering case with outdoor wind and communicate; The both sides of heat-exchanging chamber are installed and are all provided with inlet air net.The utility model structure is simple, satisfactory for result, does not need to add the special equipment outdoor wind being carried out to special heating, and just can make to enter indoor wind has uniform temperature, and indoor temperature can not be made to reduce.
Description
Technical field
The utility model belongs to agricultural technology field.
Background technology
Ventilation is the major part of confined swine housing environmental Kuznets Curves, and pig house draft type is divided from large aspect and mainly contained force ventilation, gravity-flow ventilation two kinds of type sepecies.
What force ventilation application was more is exhaust ventilation system, is extracted out by room air by force, form instantaneous negative pressure by ventilating fan, and outdoor air flows into indoor under atmospheric pressure effect by air inlet.Although this kind of draft type structure is relatively simple, small investment, in high and cold area winter, the reduction of temperature in house certainly will be caused, increase heating energy consumption.Positive pressure ventilation system can to entering the pretreatment such as air heats, cools, filtration, effectively can ensure the stability of suitable warm and humid situation in pig house and clean air ambient.
Its principle of Natural Ventilation Mode is under the effect of the hot pressing caused by the temperature difference, drive the air natural of the interior space to flow, although ventilation energy consumption is lower, affects comparatively large, be difficult to meet the air-conditioning requirement in house by factor of natural environment.
Pig house air intake in winter in high and cold area requires the top air intake at pig house, flows to bottom, avoid the quench effect that the direct air intake in bottom produces pig with in house after air mixing preheating.Winter, the cold air of outdoor directly entered in house, certainly will reduce temperature in house, increase in house for thermal energy consumption.
Summary of the invention
The purpose of this utility model is to provide a kind of without peripheral hardware firing equipment, closes pig house heat exchange open air exhaust device at cold snap by heat exchange to the high and cold area passing into warm braw in pig house.
The utility model is that indoor wind discharges case in the upper end of device, and lower end is that outdoor wind enters case, and indoor wind discharges case the outlet communicated with the external world, and outdoor wind enters case the air intake vent communicated with indoor; The negative and positive dividing plate being provided with positive passage and cloudy passage composition in heat-exchanging chamber that case and indoor wind discharges between case is entered at the outdoor wind of device, not connected between sun passage and cloudy passage, sun passage has to discharge the indoor wind that case communicates and exports with indoor wind, cloudy passage has the outdoor wind entrance entering case with outdoor wind and communicate; The both sides of heat-exchanging chamber are installed and are all provided with inlet air net.
The utility model structure is simple, satisfactory for result, does not need to add the special equipment outdoor wind being carried out to special heating, and just can make to enter indoor wind has uniform temperature, and indoor temperature can not be made to reduce.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model removes inlet air net;
Fig. 2 is that the A-A of the utility model Fig. 1 is to schematic diagram;
Fig. 3 is that the B-B of the utility model Fig. 1 is to schematic diagram.
Embodiment
The utility model is that indoor wind discharges case 1 in the upper end of device, and lower end is that outdoor wind enters case 4, and indoor wind discharges case 1 outlet communicated with the external world, and outdoor wind enters case 4 air intake vent communicated with indoor; The negative and positive dividing plate 3 being provided with positive passage 5 and cloudy passage 6 and forming is entered in heat-exchanging chamber that case 4 and indoor wind discharges between case 1 at the outdoor wind of device, not connected between sun passage 5 and cloudy passage 6, sun passage 5 has to discharge the indoor wind that case 1 communicates and exports 7 with indoor wind, cloudy passage 6 has the outdoor wind entrance 8 entering case 4 with outdoor wind and communicate; The both sides of heat-exchanging chamber are installed and are all provided with inlet air net.
Negative and positive dividing plate 3 end face that its middle-jiao yang, function of the spleen and stomach passage 5 and cloudy passage 6 form becomes dentation, and closes stuffy between positive passage 5 and cloudy passage 6 completely.Negative and positive dividing plate 3 adopts easier Heat Conduction Material better effects if.
The course of work:
Indoor hot air enters positive passage by the inlet air net of the inboard of heat-exchanging chamber, then by the heat conduction of indoor wind to negative and positive dividing plate, then enter indoor wind by the outlet of indoor wind and discharge case, outside last discharge chamber.
Outdoor cold wind enters cloudy passage by the inlet air net in the outside of heat-exchanging chamber, then absorbs the heat energy that negative and positive separator plate conductive is come, and by outdoor cold air heating, then enters outdoor wind by outdoor wind entrance 8 and enters case 4, finally send into indoor.
By the heat exchange method of this structure, save mass energy, the heat energy utilization of the discarded energy is got up, after outdoor cold wind utilizes this heat energy to enter indoor, the temperature of indoor can not be reduced.
