An environmentally friendly grain drying system

Abstract

An environmentally friendly grain drying system comprises a drying tower, wherein a drying section is arranged on the drying tower; an air inlet channel is formed in one side of a tower wall of the drying section; an air outlet channel is formed in the other side of the tower wall of the drying section; a plurality of pipe cavities are formed in the drying section; a hot-blast stove is arranged on one side of the drying tower; a first fan is arranged on the hot-blast stove and communicates with the air inlet channel of the drying section; a second fan is arranged on the other side of the drying tower and communicates with the air outlet channel of the drying section; the drying tower is further provided with a dust removal filter, a dehumidification filter and a third fan; the second fan is connected with the dust removal filter; the dust removal filter is connected with the dehumidification filter; the dehumidification filter is connected with the third fan; and the third fan communicates with the inside of the hot-blast stove. The environmentally friendly grain drying system is further provided with a heat pump unit, an underground water circulating pipe and a hot water circulating pipe; the hot water circulating pipe, the underground water circulating pipe and the heat pump unit form a circulating loop; the hot water circulating pipe is distributed in a pipe cavity of the drying section; and the underground water circulating pie is buried under the ground. The environmentally friendly grain drying system is high in energy utilization rate, low in energy consumption and low in environment pollution.

Description

technical field [0001] The invention relates to a drying system, in particular to an environment-friendly grain drying system. Background technique [0002] The main body of most of the existing grain drying equipment is composed of a furnace and a drying tower that provide hot air. Burn combustibles and deliver hot air for drying. Although this type of drying method can quickly heat up, it will inevitably produce smoke and a variety of harmful gases, and the hot air of the grain drying equipment is open, and the hot air is directly discharged after heating, which not only causes environmental pollution, Cause heat to dissipate again, waste energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned background technology and provide an environment-friendly grain drying system with high energy utilization rate, low energy consumption and little environmental pollution. [00...
