The invention discloses a hot smoke recycling system. The system comprises a boiling furnace and chimneys, wherein the boiling furnace is divided into two chamber bodies; primary fans are respectively arranged at the bottoms of the two chamber bodies; smoke exhausting pipelines are respectively arranged at the top ends of the two chamber bodies of the boiling furnace; one smoke exhausting pipeline is sequentially provided with a heat exchanger, an electric dust collector, a main draught fan and the chimney; the other smoke exhausting pipeline is sequentially provided with a mixing chamber, a beater, the electric dust collector, the main draught fan and the chimney; the main draught fan on one smoke exhausting pipeline and the inlet of each primary fan are respectively provided with a hot air pipeline; a smoke reflowing pipeline is arranged between the main draught fan on the other smoke exhausting pipeline and the mixing chamber; a flashboard is arranged inside each chimney and is controlled by an electric servo executing mechanism. The hot smoke recycling system disclosed by the invention has the beneficial effects of circularly utilizing heat, saving energy and being more environment-friendly.
Description
technical field [0001] The invention relates to a thermal energy recycling system, in particular to a hot flue gas recycling system. Background technique [0002] In recent years, the output of gypsum board in my country has achieved an increase of more than 20% per year, but the per capita gypsum board share is far behind developed countries. Therefore, production processes and equipment that not only improve production efficiency but also save energy are needed. At the same time, the country's energy and The attention to environmental protection is constantly increasing. Therefore, reducing unit consumption and production costs and reducing pollution emissions have become technical hotspots. The production of gypsum boards from desulfurized gypsum boards not only solves the problem of solid waste in thermal power plants, but also provides cheap raw materials for gypsum board factories. However, desulfurized gypsum usually contains 12%-15% of adsorbed water, and energy cons...
