Glass kiln exhaust gas waste-heat utilization and exhaust gas desulfurization system

Abstract

The invention provides a glass kiln exhaust gas waste-heat utilization and exhaust gas desulfurization system which comprises a melting tank of a glass kiln, wherein the melting tank is connected with a working tank through a throat; an oil gun is arranged at the bottom of the melting tank; a heat storage chamber is arranged on the other side of the melting tank; the heat storage chamber is connected with a waste-heat boiler steam pot through a boiler exhausting pipe; the waste-heat boiler steam pot is heated and dried by the heat storage chamber through a vaporizing pipe and then is in parallel connection with the oil gun; a main flue is arranged at the top of the heat storage chamber; an exhaust gas gate is arranged on an outlet position of the main flue; an exhaust gas outlet is formed on the rear side of the exhaust gas gate; and an exhaust gas desulfurization system is arranged on the rear side of the exhaust gas outlet. The system can fully utilize the outward dispersing waste heat of the glass kiln, can additionally generate a large amount of steam for production and life, can save energy and can reduce environmental pollution. The exhaust gas desulfurization system is used for increasing the exhaust gas treating efficiency and reducing the damage of harmful matters to a human body.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a waste heat utilization and waste gas desulfurization system of a glass furnace. Background technique [0002] At present, in the process of glass fiber production at home and abroad, the exhaust gas of glass fiber kiln contains a certain amount of harmful exhaust gas such as sulfur dioxide and hydrogen fluoride. Because sulfur dioxide and hydrogen fluoride gas have a great impact on human health and great damage to the environment , so the country has always been stricter in management, especially in recent years, it has put forward stricter and newer requirements for exhaust emissions containing the above-mentioned exhaust gases. At the same time, the existing glass furnace consumes a lot of energy and has low thermal efficiency. Generally, the thermal efficiency of small and medium-sized glass furnaces is about 25%, and the lost heat energy cannot be reused, and its ...

At the same time, the existing glass furnace consumes a lot of energy and has low thermal efficiency. Generally, the thermal efficiency of small and medium-sized glass furnaces is about 25%, and the lost heat energy cannot be reused, and its chimneys also pollute the environment. , besides, additional production and domestic boilers are needed in the factory area, which not only consumes extra energy but also causes further pollution to the environment
