Description
Technical Field
The invention relates to the technical field of pig and poultry breeding, in particular to an energy-saving, environment-friendly and efficient pig farm which is suitable for modernized pig and poultry feeding and is most suitable for a heat-insulating and airtight pigsty.
Background
The modern high-efficiency intensive pig farm is mainly designed from Europe and America. The climate conditions of the major pig raising areas in Europe and America are very different from those of the major pig raising areas in China, so that the European and American mode pig farm does not show real high efficiency in China.
Because the summer climate of the main pig raising areas in Europe and America is dry and cool, the method for cooling the pigsty in the areas mainly comprises ventilation, evaporation and air cooling effect brought by wind speed. When the pigsty is designed, the ventilation quantity meeting the summer maximum ventilation mode is taken as the equipment installation standard, pregnant sows are taken as an example, the summer maximum ventilation quantity is up to 800-1000 cubic meters per hour, and the winter minimum ventilation requirement is only 35 cubic meters per hour, so the requirement on equipment is very high. In the last decade, experts in the pig industry in China have made many innovations, but most of them do not completely get rid of the influence of the thought of regulating environmental factors by ventilation volume formed in Europe and America. Meanwhile, the regulation and control means of taking away heat by ventilation, regulating temperature by a wet curtain and supplementing heat by a gas/oil heater is difficult to control the temperature and the humidity within ideal ranges in high-temperature and high-humidity seasons in most areas in China.
In recent years, air filtration is increasingly adopted by pig farms due to the importance of pig farm biosafety by pig raising enterprises. Although air filtration can solve the problem of disease control well, it also brings about an increase in investment (cost of the air filtration equipment itself, an increase in building area due to increased air filtration, an increase in fan investment, etc.) and an increase in running costs (cost of replacing the air filter, labor costs, and an influence on production during replacement). The higher the ventilation requirements of the pigsty, the higher the above costs and expenses. In addition, with the improvement of the living standard of people, the requirements of common people on the living environment are higher and higher, and the air pollution problem of a pig farm is also paid more and more attention. Many pig farms are beginning to install tail gas deodorising apparatus. Also, the investment cost and the operation cost of the exhaust gas treatment device are very high also because of the large ventilation amount.
In recent years, some enterprises in the domestic pig industry adopt heat pumps as cooling tools for high-value pig farms such as boar stations and lactating sow houses, but still adopt a main line logic of 'adjusting temperature by ventilation quantity, adjusting temperature by wet curtains and supplementing heat by gas/oil heaters', and use heat pumps as a supplementary cooling means. This pig farm is relatively high in investment, very high in operating cost, and not ideal in environmental control.
Based on the background, the pig raising industry needs a pig farm which can control the environmental conditions of a pigsty in a relatively ideal state, can realize air filtration, can deodorize tail gas, and has low investment and low cost.

The present embodiment differs from embodiment 1 in the way of transferring heat between different facilities in a pig farm by means of a heat pump, as shown in fig. 6:
(1) and if the total amount of heat generated by refrigerating the pigsty I1-1 in summer is calculated to be approximately balanced with the total amount of heat required by heating in winter, so that the pigsty I1-1 establishes an independent ground source heat pump system. The heat generated when the pigsty is refrigerated in summer is stored in the ground source well, and the heat is extracted from the ground source well in winter to be used for heating the pigsty.
(2) And if calculated, the total quantity of heat generated by refrigerating the pigsty II 1-2 in summer is higher than the total quantity of heat required by heating in winter, but is approximately equal to the sum of the quantity of heat required by heating a fermenter, the quantity of heat required by evaporating a reservoir and the quantity of heat required by heating the pigsty in winter, so that the pigsty II 1-2, the field office area 5, the fecal sewage treatment facility 8, the reservoir 6, the hot water storage device 7 and the ground source well 10 form a heat pump system, the heat generated by refrigerating the pigsty and the field office area in summer is partially used for heating the fermenter, the reservoir and the hot water storage device, and the heat is stored in the field source well, and the heat is taken from the field source well in winter for heating the field office area, the pigsty, the fermenter and the hot water storage device. The reservoir does not need to be heated in winter.
(3) If the calculation shows that the pigsty III 1-3 does not need to be heated in winter or the demand is very small, the pigsty adopts an air energy heat pump, and heat generated by cooling the pigsty in summer is directly radiated in the air.
