Progressive small and medium sized in-storehouse ventilation system with pumping, air exchanging, dehumidifying and cooling functions

Abstract

The present invention provides a progressive small and medium sized ventilation system for storehouse internal use with pumping, air exchanging, dehumidifying and cooling functions. A fan inlet is connected with an inlet end ventilation single tube, and a fan outlet is connected with a strake heat-transferring condensation chamber through a compressor-type dehydrating and cooling device, the strake heat-transferring condensation chamber is then connected with an air-exchanging chamber, which is connected with an outlet end ventilation single tube. When the ventilation system is in use, the inlet and the outlet of the fan are pumped with the single tubes, thus airflow rate is quickened compared with the situation that only the single tubes are used to pump the air, and the temperature can be lowered more quickly. Because of the existence of water-sucking substances and loopholes in the air-exchanging chamber, air exchanging and dehumidifying can be realized. Heat transfer between high temperature grain pile gas and circulating water, and condensation dehydrating can be realized through the strake heat-transferring condensation chamber, and the process is secondary dehydrating and cooling. The compressor-type dehydrating and cooling device adopts tertiary dehydrating and cooling. The ventilation system realizes progressive dehydrating and cooling as a whole, increases efficiency, and leads the ventilation of the single tubes to be effective and efficient. Moreover, the small and medium sized ventilation system is convenient and handy, and can be used in storehouse.

Description

Technical field: [0001] The invention relates to a ventilation system, in particular to a hierarchical suction, ventilation, dehumidification, cooling and ventilation system in small and medium-sized warehouses that can dehumidify, cool and ventilate, and accelerate the gas exchange of grain piles, especially the gas exchange at heat points. Background technique: [0002] At present, the treatment of heating points in grain piles in the grain system often adopts single-pipe ventilation, that is, the single-pipe system full of holes is inserted into the grain pile for ventilation, and the temperature of the heating points is lowered by air flow. Due to the different density of grain piles, single-pipe ventilation takes a long time, and it is not obvious to cool down when encountering high-impurity areas with poor airflow. [0003] At present, the dehumidification and cooling devices commonly used in the grain industry include grain coolers. The grain coolers are large in size...

Problems solved by technology

[0002] At present, the treatment of heating points in grain piles in the grain system often adopts single-pipe ventilation, that is, a single-pipe system full of holes is inserted into the grain pile for ventilation, and the temperature of the heating points is lowered by air flow. Due to the different density of grain piles, it takes a long time for single-pipe ventilation, and it is not obvious to cool down when encountering high-impurity areas.

[0003] At present, the dehumidification and cooling devices commonly used in the grain industry include grain coolers. The grain coolers are large in size and difficult to operate in the warehouse. Because of their high energy consumption, their use in the grain industry is limited. The grain industry urgently needs a medium-sized A graduated suction, ventilation, dehumidification and cooling ventilation system in small and medium-sized warehouses that can be used in the warehouse

[0004] The traditional single-pipe ventilation fan in the grain industry performs suction alone, and it is difficult to play the role of the fan. The condensed precipitation and physical water absorption have not been developed and utilized, and because the temperature outside the warehouse is relatively high during summer operation, the traditional single-pipe ventilation is more difficult. Large, even high-temperature air is introduced into local heating points, which makes it difficult to achieve the purpose of single-pipe ventilation. The traditional valley cooler has a relatively high initial temperature, so the energy consumption of the valley cooler is very large, and the work efficiency is relatively limited.
