一种密闭式鸡舍通风系统及气流组织方法 A sealed-type house ventilation and air distribution methods

技术领域 FIELD

[0001] 本发明属于设施农业领域,具体涉及一种密闭式鸡舍通风系统及气流组织方法。 [0001] The present invention belongs to the field of agricultural facilities, particularly, to a closed house ventilation system and air distribution method.

背景技术 Background technique

[0002]作为畜牧生产中集约化程度最高的蛋鸡产业,基本上都采用全密闭鸡舍饲养。 [0002] As the level of intensive livestock production industry highest layers, basically using fully enclosed rearing sheds. 纵向通风是密闭鸡舍普遍采用的气流组织模式。 Ventilation Air longitudinal mode is closed sheds commonly used. 纵向通风是指将鸡舍的负压风机(排风口)集中布置在一端的山墙上,在与之对应的另一端山墙或山墙附近的纵墙上布置进风口,在负压作用下,使鸡舍内的气流从进风口进入鸡舍内后,沿着鸡舍纵墙方向向排风口移动。 Vertical ventilation of the house refers to a suction fan (exhaust port) is arranged at the gable end concentration in the corresponding end of the other vertical gable or gable wall near the air inlet is disposed in the negative pressure, so that after the house airflow from the air inlet into the house, the house moves to the exhaust port along the longitudinal direction of the wall. 与传统的横向通风比较,这种气流组织形式有效地增加了鸡舍内平均风速,气流分布也更为均匀。 Compared with the conventional lateral ventilation airflow which form effectively increases the average wind speed within the house, and more uniform flow distribution. 该通风配备湿帘风机降温系统,普遍解决了夏季高温造成蛋鸡减产和死淘率增加的问题,成为现代养鸡环境调控技术的一项重要突破。 The ventilation is equipped with wet curtain fan cooling system, generally solve the problem caused by high temperatures in summer and increase egg production rate of death and to become a major breakthrough in modern chicken environmental control technologies.

[0003] 然而,随着鸡舍内饲养密度和单栋饲养量的不断增加,传统的纵向通风的气流组织模式的问题不断凸显,主要表现在以下几个方面:1、笼养鸡舍的通风降温原理不明确。 [0003] However, with the increasing stocking density and the single-family house of rearing volume, the problem of conventional organizational model longitudinal ventilation air continue to highlight, mainly in the following aspects: 1, Yangji ventilation homes cooling principle is not clear. 通过增加动物身体周围的风速以产生风冷效应,进而降低动物的体感温度,是夏季舍饲畜禽降温的重要原理,但是,蛋鸡普遍采用笼养形式,密度很大,笼子和鸡的共同阻力很大,即便是通道的风速很大时,笼子内和笼附近的风速也很小。 By increasing the wind speed around the body of the animal to produce air-cooled effect, thereby reducing the body temperature of the animal sense, it is an important principle of feeding livestock cool in summer, but hens cage commonly used form of great density, and chicken cages together great resistance, even when the wind speed is large channels, cages, and the wind speed near the cage is small. 因此,通过风冷效应来实现蛋鸡舍的降温方式是不科学的。 Therefore, the way to achieve cooling by air cooling effect of laying house is unscientific. 那么如何更好地实现笼养蛋鸡的通风降温效率,目前还没有人对此进行相关的研究和报道。 So how to better achieve the caged layer of ventilation and cooling efficiency, no one has yet conducted this research and related reports. 2、进、排风口温差大。 2, air intake and exhaust port temperature difference. 鸡舍内温度从进风口向排风口逐渐升高,有的鸡舍前后温差高达5_8°C,鸡舍尾端鸡群热应激严重。 House temperature was gradually raised from the air inlet to the air outlet, the temperature difference before and after some sheds up 5_8 ° C, the trailing end of the flock house severe heat stress. 进、排风口温差大主要与舍内平均风速、饲养量等有关。 Jin, the temperature difference between the exhaust port and the main discounted average wind speed, raising the amount and so on. 当平均风速保持不变时,饲养量越大,单位时间内鸡体向鸡舍内散发的热量越多,两者的温差越大;当饲养量保持不变时,风速越低,单位时间内带走的热量越少,两者温差越大。 When the average wind speed remains constant, the greater the feeding quantity per unit time more distributed into the chicken house of heat, the greater the temperature difference between the two; remains unchanged when feeding amount, the lower the wind speed per unit time the less heat away, the greater the temperature difference between the two. 3、鸡舍内气流分布不均匀。 3, non-uniform flow distribution within the house. 不同走道的风速大小存在差异,主要受进风口与走道的相对位置影响,风速小的走道,温度高,两者的耦合效应,会加重鸡群的热应激,严重影响产蛋率和蛋品质。 Presence of different wind speed difference walkway, mainly due to the relative position of the air inlet and the influence of the walkway, the wind speed is small walkway, high temperature, both coupling effect, will increase the heat stress in chickens, seriously affecting egg production and egg quality . 同一走道沿鸡舍长度方向,靠近进风口、排风口两端风速大,中间风速小。 Walkway along the longitudinal direction of the same house, close to the air inlet, the air outlet ends wind speed, wind speed is small intermediate. 4、进风口设计不合理,导致气流组织紊乱,通风阻力大。 4, inlet design is unreasonable, leading to tissue disorder airflow, the ventilation resistance is large. 实际生产中,为了增加鸡舍内进气口的气流速度,多在湿帘进风口与鸡笼首架之间设置一道布满整舍横截面的垂直挡板,在挡板上开启洞口作为通风口。 In actual production, in order to increase the intake port of the air velocity house, in a multi-wet curtain air intake disposed between a first aircraft and the cages covered the whole rounded cross section perpendicular to the baffle, the baffle plate opening as a ventilation hole in mouth. 由于挡墙洞口小于横截面积,通过洞口进入舍内的初始气流速度明显增大。 Since the hole wall is smaller than the cross-sectional area, the initial flow velocity through the hole into the discounted significantly increased. 但是,湿帘进风口与垂直挡板之间的气流紊乱,没有组织性,通风阻力显著增加,造成能源浪费。 However, turbulent airflow into the wet curtain between the air and the vertical flaps, no organization, a significant increase in ventilation resistance, resulting in energy waste. 5、鸡笼前端阻挡气流运动,气流紊乱,通风阻力大。 5, the front end of the blocking air movement cages, airflow turbulence, the ventilation resistance is large. 现有鸡舍进风口呈细长型,水平设置,进风口与鸡笼垂直交叉布置,鸡笼阻挡气流运动,导致该段气流运动组织性差,紊流严重。 Conventional house inlet was elongated, horizontally disposed, and an air inlet disposed perpendicularly crossing cages, cages blocking air movement, air movement causes the section of tissue is poor, severe turbulence.

[0021] 本发明提出了一种针对笼养蛋鸡舍(特别是叠层笼养鸡舍)通道通风系统及气流组织形式,以改善笼养鸡舍的通风均匀性,提高通风效率、降低通风能耗。 [0021] The present invention provides a ventilation system and air distribution channels for caged laying house (especially laminate Yangji round) form, in order to improve the uniformity of the ventilation Yangji homes, improve ventilation efficiency, reducing ventilation energy consumption.

[0022] 1、针对笼养鸡舍通风降温原理不清楚的问题,本发明中提出了笼养鸡舍二次对流的间接降温原理。 [0022] 1, Yangji homes for ventilation and cooling principle is not clear, the present invention proposes a second round of indirect cooling principle Yangji convection. 简单概括为:在风机作用下,鸡舍内外发生强制对流,使鸡舍通道的温度降低。 Summarized as: under the action of the fan, forced convection occurs inside and outside the house, the temperature of the house channel decreases. 鸡笼内与通道之间产生温差,鸡笼内温度比通道内温度高,热量从高温流向低温,在自然对流的作用下,鸡笼内的热量扩散到过道内,再通过通道的强制对流将热量排出舍外,从而间接达到鸡群降温的目的。 Generated in the cages and the temperature difference between channels, cages inside temperature is higher than the temperature within the channel, the flow of heat from the low temperature, under the effect of natural convection, diffusion of heat in the cages into the aisle, then the channel will be by forced convection exhaust heat outside the house, so as to achieve the purpose of indirect cooling flocks.

[0023] 2、针对进、排风口存在温差大的问题,本发明中以射流为主的通道靶向通风模式,将进风口与排风口都对准通道设置,使新鲜气流通过进风口直接射入通道,以最大程度减少舍内的通风阻力,提高通风内气流速度,进而减少鸡舍进、排风口温差。 [0023] 2, for the air intake and exhaust port there is a large temperature difference, the present invention is mainly a jet channel targeting the vent mode, the inlet and exhaust ports are aligned with channel set, so that fresh air flow through the air inlet directly into the channel, to minimize the discounted ventilation resistance, increase ventilation airflow rate, thereby reducing house air intake and exhaust port temperature difference. 气流速度增加,虽不能完全消除进、排风口的温差,但可以最大程度的减少两者温差,尽可能缓减尾端鸡群的热应激。 Air flow rate increases, though not completely eliminate air intake and exhaust outlet temperature difference, but it minimizes the temperature difference between the two, as the end of flocks of heat stress mitigation. 此外,进风口设置了可调的双扇导流板,通过调节双扇导流板的开启角度,改变进风口大小进而控制进风口射流速度。 In addition, the air inlet is provided with adjustable double fan baffles, double fan opening angle by adjusting the deflector to change the size of the inlet air intake and then control the jet velocity. 通风量不变时,进风口宽度变小,通风面积变小,通风速度就会增加。 When the same amount of ventilation air inlet width becomes smaller, the ventilation area becomes smaller, the speed will increase ventilation.

[0024] 3、针对鸡舍内气流分布不均匀的问题,本发明设计了进风口前端导流装置,使每条通道所分享的进风口面积大小尽量一致,从而使射入通道内的气流体量相同,保障每条通道内的气流速度相近。 [0024] 3, for the air distribution problems within the house uneven, the present invention is designed to guide the front end of the air inlet means, so that each inlet channel shared area size be consistent, so that the airflow enters the channel in the body the same amount, the flow velocity close to protect each channel. 增加进入通道的初始气流速度并尽量减少通道的通风沿程阻力,可有效缓减同一通道前、中、后端风速分布不均的问题。 Before increasing the initial velocity of the incoming gas flow channel and to minimize the resistance along the ventilation passage, which can effectively mitigate the same channel, the problem of uneven distribution of the rear end of the wind speed.

[0025] 4、针对进风口处气流组织紊乱、通风阻力大的问题,本发明中通过设置导流板引流方式,使气流有组织的、顺畅地射入通道,而不形成涡流,从而最大程度的减少通风阻力,增加通风效率。 [0025] 4, for the air distribution disorders, major problems ventilation resistance at the air inlet, the present invention is provided by way of the drainage guide plate, the airflow organized smoothly enters the channel, without the formation of a vortex, in order to maximize ventilation resistance is reduced, increasing the ventilation efficiency.

[0026] 5、针对现有鸡舍进风口呈细长型水平布置,进风口与鸡笼垂直交叉,鸡笼对气流产生阻挡造成气流紊乱的问题,本发明中将进风口设计为细高型并针对通道竖直设置,气流从进风口射流直接进入通道,实现气流的有效组织,减少通风阻力。 [0026] 5, into the existing house air was horizontally arranged elongated, perpendicularly crossing the air inlet and cages, cages problems caused by turbulent airflow barrier to the air flow, in the present invention is designed as a fine high inlet type and set for the vertical channel, the jet stream from the air inlet directly into the channel, to achieve an effective tissue airflow, reducing ventilation resistance.
