Description
Technical field
The utility model belongs to industrialized agriculture field, relates to a kind of confined poultry house winter ventilation system.
Background technology
As the laying hen industry that intensive degree in husbandry sector is the highest, in order to reduce the impact that external environment change is produced laying hen as far as possible, farthest realize house environment artificial regulatory, scale laying hen field all adopts totally-enclosed drylot feeding to support.Stable, good air ambient can be provided particularly important for Laying House, direct relation the success or failure that poultry is produced, and is subject to the great attention of relevant insider and expert.
Longitudinal ventilation adds wet curtain cooling system and is widely used in China's laying hen production, generally solves the problem that summer high temperature causes the laying hen underproduction and death rate to increase, and becomes an important breakthrough of modern poultry environment conditioning technology.For Laying House pollution control problems in winter, do not obtain enough attention, a lot of expert and insider think, the building of China's Laying House is simple and crude, sealing is poor, add that the ventilation needed for laying hen winter is few, based on insulation, should can be met the ventilation needs of Laying House in winter by crack between a door and its frame, window seam etc.
Along with the raising of China's layer breeding level, for pursuing higher production efficiency, focus on very much the stocking density of unit are, at 18-20/m as raised in cages in ladder
2, lamination is raised in cages even up to 40 ~ 60/m
2.When in giving up, stocking density constantly increases, emphasize simply to be incubated in environment of chicken house regulation and control winter and think little of the way of ventilation, cause serious deficiency in draught in house, dust is large, air is dirty, then cause chicken group respiratory disease to take place frequently, the event of the chicken group that even occurs suffocating.Winter environment regulation and control problem is day by day serious, has caused showing great attention to of insider.In recent years, the air vent mode of side wall fenestella air intake or roof air intake was introduced and was widelyd popularize, and has filled up China's laying hen winter ventilation disappearance problem, improve house environment to a certain extent, played the hereditary potential of laying hen preferably from technical standpoint.
When adopting side wall fenestella air intake or roof air intake, blower fan is generally even to be arranged in the longitudinal direction of both sides, and air-flow moves along gable direction, forms transversal ventilation pattern.Under the effect of automatic control program, the large I that air inlet is opened adjusts according to ventilation needs in house.Its general principle is under fan action, and form negative pressure in house, air-flow is injected in house through fenestella gap, adherently along roof moves ahead, and then sinks, and discharges outside house, as shown in Figure 1 from blower fan.Under the effect of automatic control program, the large I that air inlet is opened adjusts according to ventilation needs in house.When in house, negative pressure is 10 ~ 15Pa, the horizontal range about 7 ~ 12m of every side air inlet.This draft type is in flat poultry house, and can realize the relatively uniform distribution of air-flow, but raise in cages in hen house, particularly lamination is raised in cages in hen house, and because the resistance of chicken coop is very large, the air flow method of hen house is seriously obstructed, as shown in Figure 2.There is following problem in this:
(1) fresh gas flow layout is in each channel extremely uneven, causes the temperature in different passage and air quality (such as oxygen concentration, harmful gas concentration etc.) to there is larger difference.Under transversal ventilation pattern, air-flow injects in house by the mode of high-speed jet (2-3m/s) is adherent along roof.Along with range increases, the moving ahead of air-flow slows and starts to sink, and this makes the region down channel being positioned at air-flow rapid movement almost not have fresh air to enter.
(2) air quality of different cage layer there are differences.After air-flow admission passage, naturally sink under gravity, carry out exchange heat with the hot-air floated by convection type; Meanwhile, horizontal movement under the effect of negative-pressure air fan, and discharged outside house by negative-pressure air fan.Once horizontal motion speed is greater than natural subsidence speed, just there will be situation about to be just discharged when fresh gas flow does not arrive bottom cage outside house, this causes the air quality of the chicken group periphery being in lower floor poor, affects the performance of productivity.Experimental data proves, this phenomenon ubiquity.
(3) near blower fan, wind speed is comparatively large, air quality is poor.During transversal ventilation, wind turbine layout is on vertical wall, and under fan action, in house, vitiated air is assembled to exhaust outlet, and this causes wind speed in the passage of vertical wall comparatively large, and air quality is poor.In addition under jet action, fresh air can not enter this passage under jet action, and the chicken group that three's coupling has a strong impact on this passage proximate is healthy, and this region is also often the starting and region that takes place frequently of disease in house.
(4) air cross infects serious.Under exhaust outlet is arranged in import wind, the vitiated air that may be discharged by blower fan enters in house again, or enters next door hen house, and She Waijingwu road is not separated, and cross-infection is serious.
