Description
Technical field
The present invention relates to ventilating system technical field, and in particular to a kind of displaced type ventilating system.
Background technology
With the continuous scale of pig industry, the development of modernization, more and more modernize large-scale pig farm and emerge
Come.There is the characteristics of pig quantity is more, density is big on each pig farm, and this compared with enclosed environment in pig house, air quality directly affects
The health degree of pig, good Design of ventilation not only can provide comfortable environmental condition to pig, improve the general level of the health of swinery,
The generation of disease is reduced, and feeding management cost can also be reduced, reaches the effect got twice the result with half the effort for pig farm cultivation.
To ensure the air quality in pig house, present large-scale pig house is fitted with ventilation unit, except in the installation of pig house wall
Outside window, wind turbine also usually is installed above pig house wall, air is passed through into pig house by wind turbine, keeps air stream in pig house
It is logical.Such device has the following disadvantages：Ventilation effect is poor, and the flowing of air rests on the top of pig house, the sky below pig house
Gas exchanges slowly, and dead angle occurs in pig house, is unfavorable for keeping fresh air ventilation below pig house, and the pig manure below pig house is proper
Just it is the major source of pig house foul atmosphere, the fresh air that the foul smell of pig manure cannot be passed into exchanges, and air quality is still disliked
It is bad, do not reach the Expected Results for improving pig house air quality.
The content of the invention
In view of the above-mentioned problems, it is necessary to provide a kind of displaced type ventilating system, which can be to pig house
Fresh air is inside continuously passed through, while takes the exhaust gas in pig house away, keeps pig house inner air flow.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of displaced type ventilating system, applied to the farm of multi-floor building structure, is equipped with each layer building
The aisle of one connection same layer both sides, the opposite sides in each layer aisle, which is spaced, is equiped with some pig houses, each layer of institute
The interlayer that building is equipped with below the pig house is stated, if the ground between some pig houses of each layer offers involvement
Lead to the ventilation hole of the interlayer, the opposite end of each layer building offers air intake passage, the air intake passage connection
The interlayer；Each layer building offers the air-out passage for connecting some ventilation holes, each layer on the aisle
The air-out passage communicates, and each layer air-out passage is towards offering some outlet air on a side wall of the pig house
Mouthful, one first wind turbine is mounted on each air outlet, the roof of the building is equiped with some outlet air of a connection
The chimney of passage.
Preferably, the building includes at least three layers.
Preferably, the air intake passage offers the extraneous air inlet of connection, and cascade is equiped with the air inlet.

Air inlet.
Preferably, air refrigerator, the inlet end connection institute of the air refrigerator are also equipped with the air intake passage
The outlet side of air filter is stated, the outlet side of the air refrigerator connects the interlayer.
Preferably, the interlayer offers some air inlet holes, some air inlet holes close to the metope of the air intake passage
Connect the outlet side of the air refrigerator.
Preferably, if the ground separation between some pig houses offers dry passage, some ventilation holes are opened in
On some passages.
Preferably, the opposite sides in each layer aisle is each provided with a partition wall, and each partition wall is walked described in
The side in road is equipped with an air-out passage, and the air-out passage of homonymy is located at institute by some air outlet connections
State the pig house of aisle homonymy.
Preferably, some air outlets of the air-out passage are arranged on the partition wall close to the side of the pig house,
And some air outlets are located above the side of the pig house in each layer building.
Preferably, the roof of the building is provided with a compartment for being respectively communicated with the air-out passage and the chimney, institute
State and some second wind turbines are equiped with compartment.
Due to the adoption of the above technical scheme, the invention has the advantages that：
Displaced type ventilating system provided by the invention, interlayer is passed through by ozone by air intake passage, then by every
Layer is entered in pig house by ventilation hole from the ground of pig house, after fresh air enters pig house, is distributed, is made everywhere along the ground of pig house
Pig can breathe ozone, and a good air ambient is provided to pig.And the exhaust gas after pig breathing then passes through first
Wind turbine pumps to air-out passage, and the exhaust gas in air-out passage then is pumped to chimney by the second wind turbine, is finally arranged from chimney
Go out.The displaced type ventilating system of the present invention, takes away in pig house while fresh air is continuously fed in a steady stream into pig house
Exhaust gas, keeps pig house inner air flow, so as to provide a good growing environment for swinery.In addition, the displaced type of the present invention
Ventilating system, suitable for the farm of multi-floor building structure, even the farm of high-storey, can also easily carry out pig house
Ventilation operation, it is extremely convenient.
Displaced type ventilating system provided by the invention, is equiped with cascade on air inlet, makes to enter fresh in air intake passage
Air has the function that dedusting and cooling.Air filter and air refrigerator are installed, air inlet connection is empty in air intake passage
The inlet end of air filter, to remove the exhaust gas in fresh air, so as to ensure to convey the air matter into the fresh air of pig house
Amount.The outlet side of the inlet end connection air filter of air refrigerator, the outlet side connection interlayer of air refrigerator.Air system
Cooler can ensure that the temperature of fresh air than relatively low, is adapted to the growth of pig, while upward using hot-air, and cold air is downward
Principle, after the fresh air after cooling is entered pig house, flows, so that swinery, which is effectively ensured, to be breathed in the Near Ground of pig house
To fresh air.And the exhaust gas after pig breathing is warmmer, it can rise, not close to the zone of action of swinery, and pass through the first wind turbine
Discharged after pumping to air-out passage outside building.
