A high voltage electric assisted solar drying device and method

Abstract

The invention relates to a high voltage auxiliary solar drying device and method. A heat collecting chamber heat preservation layer is arranged on the inner side of a solar heat collecting chamber, an air inlet is formed in the right side of the solar heat collecting chamber, an air port formed in the left side of the solar heat collecting chamber is communicated with a solar drying chamber, and a thin film solar cell panel A and a heat collecting panel A are arranged on the upper portion of the solar heat collecting chamber. A drying chamber heat preservation layer is arranged on the inner side of the solar drying chamber, a water tank is arranged on the right side of the solar drying chamber, a reflector is arranged on the left side of the solar drying chamber, and an air outlet, a thin film solar cell panel B, a heat collecting panel B, a high-voltage electrode pin and a high-voltage electrode plate are arranged from top to bottom. Dry air is heated to 40 DEG C to 50 DEG C through the thin film solar cell panel A and solar energy obtained after heat collection through the heat collecting panel A, matter input by a conveying mechanism and needing to be dried is dried through the dry air and an auxiliary high-voltage electric field, and solar energy is fully utilized by a thin film solar cell panel coupling storage battery energy storage system. Solar energy and high voltage are combined, the drying rate is increased, drying efficiency is improved, a good drying effect is achieved, and the high voltage auxiliary solar drying device and method are clean, efficient and free of pollution and have wide application prospects.

Description

technical field [0001] The content of the present invention relates to the technical field of drying, in particular to a high-voltage electric-assisted solar drying device and method. Background technique [0002] With the acceleration of urbanization in our country, more and more sewage is produced. As a by-product of sewage treatment, sludge is not only a large amount, but the annual discharge of dry sludge is about 5.5×10 6 -6×10 6 t, the number continues to increase, and the composition is extremely complex. If it is not handled properly, it will cause secondary pollution and affect the normal operation of the water plant. At present in my country, sludge treatment equipment accounts for about 40%-60% of the infrastructure investment of sewage treatment plants, and sludge treatment accounts for about 50% of the treatment costs, resulting in treatment difficulties that are out of proportion to its economic costs. [0003] The traditional sludge treatment and disposal te...

Problems solved by technology

However, the moisture content of sludge is too high (generally 92%-96%), resulting in difficult transportation, large transportation volume, high treatment cost and poor economy.
