Problems solved by technology

[0005] 1. Because the difference between the temperature of the cold core grain in the grain pile and the maximum grain temperature of the grain surface is about 20°C, it is difficult to choose the temperature of the cold air entering the wind
Because the interface temperature difference in the grain pile is more than 8°C, under certain humidity conditions, it is very likely to cause condensation in the grain pile, which will cause hidden dangers to the safe storage of grain.
[0006] 2. Since the cold air passes through the entire grain pile from bottom to top, the ventilation air volume and cooling power are required to be large, resulting in high power consumption and operating costs for cooling ventilation
[0007] 3. Because the cold air is ventilated from bottom to top, it destroys the natural cooling phenomenon in the grain pile and wastes natural resources

Embodiment Construction

[0013] The present invention adopts the horizontal ventilation and cooling method, that is, adopts the method of horizontal air intake under the grain storage film on the south side of the bungalow 7 and the horizontal return air under the grain storage film on the north side of the bungalow to form a closed circulation; Circulation fan 1, surface cooler 2, external cold air supply pipe 5 connected with surface cooler 2, external cold air return pipe 6 connected with circulating fan 1, refrigerant outlet 3 and refrigerant inlet 4 connected with surface cooler 2 The connected refrigerator, at least one PVC air-conditioning air supply pipe 9 connected to the cold air supply pipe 5 outside the warehouse is provided in the east-west direction under the grain storage film on the south side of the warehouse, and the east-west direction is at least one under the grain storage film on the north side of the warehouse. A perforated PVC cold air return pipe 11 connected to the cold air re...

Abstract

The invention discloses a low-temperature crop-reserving film ventilating method and device of flat warehouse, which comprises the following parts: transverse ventilating cooling method, transverse inlet pipe, return air pipe and vertical probe pipe ventilating cooling device. The invention overcomes the deficiency of present method, which forms the cooling air loop to save the power.

Description

technical field [0001] The invention relates to an under-film ventilation method for low-temperature grain storage in a one-story warehouse and a device thereof, which are used to transport low-temperature air into the one-story warehouse, and belong to the technical field of grain storage. Background technique [0002] The height of the bundling grain in the bungalow is 6 meters, and it is equipped with an above-ground cage (or underground cage) ventilation network and a grain surface circulation fumigation network ventilation pipe. In order to make the grain storage temperature reach a low temperature or quasi-low temperature state, the low-temperature and dry air in winter is generally used, and the ventilation pipe network on the ground of the bungalow warehouse is used to ventilate and cool down, so that the temperature of the grain pile drops to 0-4 °C. Although Owens Corning extruded boards with a thickness of 2.5 cm are used around the interior walls of the warehouse...
