Problems solved by technology

Place the fresh air pipe in the manure tank, and the cold air outside the house is blown into the pipe by the blower outside the house. The fresh air in the pipe is preheated by the heat of the manure tank and then enters the pig house. The fresh air is preheated directly by the heat of the manure tank inside the house. Preheating effect, but due to the low temperature of the gas outside the house, the temperature in the septic tank is too high, which will cause serious frosting on the preheating pipe, and the pipe is easy to break

Embodiment 1

[0050] see Figure 1-Figure 4 In the fresh air preheating system shown, the livestock and poultry house includes a livestock and poultry house body 1 and a suspended ceiling 2 for the livestock and poultry house. Preheating module 3, secondary preheating module 4 and tertiary preheating module 5;

[0051] The primary preheating module 3 includes an external heat exchange chamber 6, and an air intake device and an exhaust device are arranged in the external heat exchange chamber 6;

[0052] Described air intake device comprises air intake blower 7, and described air intake blower 7 is connected with the first fresh air collecting chamber 13 by heat exchange pipeline 11, and described exhaust device comprises exhaust fan 8, and described exhaust device passes through house interior The exhaust gas outlet 9 communicates with the secondary preheating module 4;

[0053] The secondary preheating module 4 includes a septic tank 10 in the house, and a preheating ventilation channel ...

Embodiment 2

[0067] Such as Figure 2-4 As shown, during the air intake process, the outdoor air is filtered by the air intake fan and introduced into the heat exchange pipe through the air intake filter in the first step. Because the heat exchange pipe is surrounded by the exhaust gas discharged from the house, during the air intake process, the temperature of the cold air outside the house is relatively low. High exhaust heat exchange, the temperature rises and collects in the first fresh air collection chamber to complete the first-level preheating.

[0068] The fresh air in the first fresh air collection chamber enters the septic tank preheating air channel under the action of negative pressure, and enters the second fresh air collection chamber after being heated by the heat in the septic tank to complete the secondary preheating.

[0069] The fresh air preheated by the septic tank enters the top of the pig house through the air inlet pipe. Because the hot air in the pig house gathers...

Abstract

The invention discloses a livestock and poultry house fresh air preheating system suitable for a cold region. A fresh air preheating system body is arranged in a livestock and poultry house body. A first-stage preheating module comprises an out-house heat exchanging chamber, and a gas inlet device and a gas exhaust device are arranged in the out-house heat exchanging chamber; the gas inlet devicecomprises an gas inlet fan, and the gas exhaust device comprises a gas exhaust fan, and is communicated with a second-stage preheating module through in-house waste gas outlets; a second-stage preheating system comprises an in-house manure pit, the in-house manure pit is internally provided with a preheating ventilating channel, and the two ends of the preheating ventilating channel are connectedwith a first fresh air collecting chamber and a third-stage preheating module respectively; the third-stage preheating module comprises a second fresh air collecting chamber, an air inlet pipeline isarranged at the top of the second fresh air collecting chamber, leads into a ceiling of the livestock and poultry house, and penetrates through the livestock and poultry house front and back, and airoutlets are uniformly formed the air inlet pipeline. By means of the fresh air preheating system, the purposes of helping existing animal houses to lower the consumption for ventilating while the ventilation of pig houses is not influenced, and increase the air inlet temperature for pig herds while the heating cost is lowered are achieved.

Description

technical field [0001] The invention relates to the technical field of livestock breeding buildings, in particular to a fresh air preheating system for livestock and poultry houses in cold regions. Background technique [0002] In order to realize the coordinated development of pig production in the "National Pig Production Development Plan (2016-2020)" issued by the Ministry of Agriculture, factors such as environmental carrying capacity, resource endowment, consumption preference and slaughtering and processing are comprehensively considered, and regional comparative advantages are fully utilized. The layout is divided into key development areas, restricted development areas, potential growth areas and moderate development areas. [0003] The four northeastern provinces (Liaoning, Jilin, Heilongjiang and Inner Mongolia) belong to potential growth areas. Although the region has a good development environment and strong policy support, the winter in this region is cold and ...
