Problems solved by technology

[0002] At present, the traditional method of drying many products such as tobacco leaves, tea leaves, and coffee beans is to dry them naturally in the outdoor sun, which takes a long time to dry, and also needs to be dried according to the weather conditions. The work is cumbersome and cannot be actively controlled, and there is still dust The problem of pollution; at present, the drying equipment used for this kind of products on the market mainly uses electric heating to dry or boiler coal to provide heat for drying, which consumes a lot of energy and costs high, and there is still environmental pollution for boiler coal drying problems, even the dried items will be contaminated, affecting product quality

Embodiment 1

[0024] The heating medium at 20°C is heated to 90°C by the solar heat collector 1 and stored in the water collection tank 2. The heated heating medium enters the heat exchanger 4 from the upper part of the heat exchanger 4, and the 20°C cooling air entering the air inlet 3 The air is heated to 85°C hot air, and the heating medium after heat exchange flows into the water collection tank 2 from the bottom of the water collection tank 2 to be heated again, and the 85°C hot air enters the industrial drying line 6 from the air duct 5 under the pumping action of the induced draft fan 6 The moisture content of the material is dried from 45% to 15%, and the dried tail gas is purified by the tail gas purification system 9 and discharged from the chimney 10.

Embodiment 2

[0026] The heating medium at 13°C is heated to 95°C by the solar collector 1 and then stored in the water collection tank 2. The heated heating medium enters the heat exchanger 4 from the upper part of the heat exchanger 4, and cools the 10°C air entering the air inlet 3. The air is heated to 90°C hot air, and the heating medium after heat exchange flows into the water collecting tank 2 from the bottom of the water collecting tank 2 to be heated again, and the 90°C hot air enters the industrial drying line 6 from the air duct 5 under the pumping action of the induced draft fan 6 The moisture content of the material is dried from 50% to 8%, and the dried tail gas is purified by the tail gas purification system 9 and discharged from the chimney 10.

Abstract

The invention discloses a solar heat collector applied to an industrial drying system and belongs to the technical field of new energy. The solar heat collector is characterized in that two ends of the solar heat collector are inserted into a water collection tank; two ends of a heat exchanger are respectively connected with two ends of the water collection tank; the heat exchanger is installed in an air duct; an air inlet is communicated with an industrial baking line orderly via the air duct and a draught fan; the back part of the industrial baking line is orderly provided with a smoke channel, an exhaust purifying system and a chimney. The solar heat collector applied to the industrial drying system can dry material via solar energy and is advantaged by pollution avoidance, energy conservation and low cost; and the solar heat collector can be applied to various industrial drying systems.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a solar heat collector used in an industrial drying system. Background technique [0002] At present, the traditional method of drying many products such as tobacco leaves, tea leaves, and coffee beans is to dry them naturally in the outdoor sun, which takes a long time to dry, and also needs to be dried according to the weather conditions. The work is cumbersome and cannot be actively controlled, and there is still dust The problem of pollution; at present, the drying equipment used for this kind of products on the market mainly uses electric heating to dry or boiler coal to provide heat for drying, which consumes a lot of energy and costs high, and there is still environmental pollution for boiler coal drying Problems, even the dried items will be contaminated, affecting product quality. Solar energy is rich in resources, clean and hygienic, and environmentally friendly. Us...
