Embodiment 1

[0057] In the non-heating season, this system is only used for grain drying, and there is only a difference in heat source from the traditional grain drying system. The solid heat accumulator furnace 19 utilizes the low-valley electricity at night to heat, and outputs hot air to the outside when the grain is dried, and opens the third baffle plate 26 and the first baffle plate 24 .

[0058] During the drying operation, the high-temperature hot air is sent into the drying air duct 2 through the first induced draft fan 1. The present invention adopts a Y-shaped staggered air duct mode, such as Figure 5 As shown, the air volume is controlled by adjusting the first regulating valve 38 and the second regulating valve 40, enters the temperature regulating device 5, and controls the temperature in different ranges according to the needs of different drying operations, and uses the second induced draft fan 6 to pass through Drying air duct 2 sends hot blast into the grain drying towe...

Embodiment 2

[0061] In the heating season, this system is not only used for grain drying, but also used for heating in winter. The solid heat accumulator furnace 19 is heated by electricity in the low valley at night. Since the heating is 24h full-time heating, when grain drying is required, the hot air is output to the outside, the third baffle 26 is closed, the second baffle 25 is opened, and the second baffle 25 is opened. A baffle plate 24 sends the heated part of the hot air into the grain drying system.

[0062] During the drying operation, the high-temperature hot air is sent into the drying air duct 2 through the first induced draft fan 1. The present invention adopts a Y-shaped staggered air duct mode, such as Figure 5 As shown, the air volume is controlled by adjusting the first regulating valve 38 and the second regulating valve 40, enters the temperature regulating device 5, and controls the temperature in different ranges according to the needs of different drying operations,...

Abstract

The invention relates to the technical field of grain drying and clean heating, in particular to an electric heating and heat storage grain drying and clean heating combined system based on waste heat recovery. The electric heating and heat storage grain drying and clean heating combined system comprises a solid electric heating and heat storage device, a heating device and a grain drying device, wherein the solid electric heating and heat storage device is respectively connected with the heating device and the grain drying device. In a non-heating season, the solid electric heat storage device is used as a heat source to provide hot air for the grain drying device; and in the heating season, the solid electric heat storage device is used for heating for residents, heating hot water output is provided, and meanwhile part of hot air is provided for providing heat energy for the grain drying device.

Description

Technical field: [0001] The invention relates to the technical field of grain drying and clean heating, in particular to an electric heat storage grain drying and clean heating combined system based on waste heat recovery. Background technique: [0002] Grain drying is a necessary part of grain storage. For a long time, the ways of drying grain mainly include natural drying and drying. Among them, the natural drying method has the advantages of no pollution and no energy consumption. The disadvantages are mainly low efficiency and large environmental impact; the existing heat sources for grain drying include coal, heat pumps, and solar energy. The use of coal for grain drying is cheap, but the disadvantage is that it needs to produce carbon dioxide, sulfur, nitrogen, dust and other substances that seriously pollute the environment, and its drying quality is not high. Heat pumps have high requirements for ambient temperature and are not resistant to cold, which is not conduc...
