Environment-friendly energy-saving equipment for waste gas burning and waste heat utilization

Abstract

The invention discloses an environment-friendly energy-saving equipment for waste gas burning and waste heat utilization. The equipment comprises a hot air circulation system, an environment-friendlytreatment system, a waste heat cyclic utilization system and a discharge system; the hot air circulation system comprises a curing furnace and a curing furnace heating chamber, wherein a sprayed workpiece to be cured is placed in the curing furnace, a first burner is arranged in the curing furnace heating chamber and is used for heating waste gas generated by curing the workpiece and supplementedair, and the curing furnace and the curing furnace heating chamber communicate with each other to form a circulation air flow passage; the environment-friendly treatment system comprises a high-temperature decomposition furnace communicating with the circulation air flow passage; the waste heat cyclic utilization system communicates with the environment-friendly treatment system and the first burner, and is connected with the discharge system. The toxic waste gas generated by curing the workpiece in the curing furnace is oxidized to be decomposed into the standard waste gas in the high-temperature decomposition furnace, the waste gas is utilized by a waste heat utilization device in the process of discharging the waste gas to the outside, in addition, waste heat of waste was generated by heating in the first burner is also utilized by the waste heat utilization device, so that the waste heat utilization and the environmental-friendly discharge are achieved.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving equipment, in particular to an environment-friendly and energy-saving equipment capable of fully incinerating waste gas produced in the spraying process and utilizing the waste heat generated by the incineration for waste gas incineration and waste heat utilization. Background technique [0002] As the frontier cities in my country's economically developed regions, southern and coastal cities in China have a considerable number of industries, such as furniture, machinery and equipment, and automobile manufacturing. Paint is used to varying degrees in the production process, most of which are solvent-based paints. . Solvent-based paints are widely used in related industries due to their mature technology, relatively low cost, and good performance. [0003] But the paint contains a lot of organic solvents, and the organic solvents contain a lot of volatile organic compounds (VOC) with for...

Problems solved by technology

Usually, the exhaust gas incinerator uses diesel oil, heavy oil or natural gas as fuel, and the exhaust gas sent to the incinerator burns in the flame of the above fuel to oxidize and decompose it. However, the higher the temperature of the incinerator furnace, the more fuel is consumed. In order to save fuel, some manufacturers adopt low-temperature combustion methods, that is, the incineration temperature is lower than 760°C (such as 700°C, or even below 600°C), so that organic solvents or other harmful components (such as phenol, formaldehyde, etc.) cannot be completely oxidized and decomposed. The above-mentioned harmful components can be detected on the exhaust chimney of the incinerator, which exceeds the national standard, and the smell of the above-mentioned organic substances can be smelled within hundreds of meters from the incinerator
