Exhaust gas afterheat recycle device

Abstract

The invention provides an exhaust gas afterheat recycle device. The device comprises a condensation tank, an upper end and lower end of the condensation tank are provided with end covers, the condensation tank is internally provided with a spiral condensation pipe, a lower end of the spiral condensation pipe is respectively connected with a gas inflow joint and a liquid collecting tank, an upper end of the spiral condensation pipe is connected with a gas discharging pipe joint, one side at a lower end of the condensation tank is connected with a water inflow joint, one side of the upper end ofthe condensation tank is connected with a water outflow joint, one side of the condensation tank is provided with a heat recycle tank, the heat recycle tank is internally provided with a spiral gas pipe, a lower end of the heat recycle tank is connected with the water outflow joint through a joint and a water pipe, a lower end of the spiral gas pipe is connected with the gas discharging pipe joint through a three-way valve and the gas pipe. The exhaust gas afterheat recycle device is novel in structure and stable in operation, can be used for realizing recycle of a volatile organic solvent inexhaust gas and second-level heat recycle treatment, is good in afterheat recycle effect, and meets current application requirement.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to an exhaust gas waste heat recovery device. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially chemical plants, steel plants, pharmaceutical plants, coking plants, oil refineries, etc., and the production of domestic waste gas from human life, the exhaust gas has a strong smell, which seriously pollutes the environment and affects human health. There are many types of pollutants in exhaust gas, their physical and chemical properties are very complex, and their toxicity is also different. The exhaust gas discharged from fuel combustion contains sulfur dioxide, nitrogen oxides (NOx), hydrocarbons, etc.; due to the different raw materials and processes used in industrial production, various harmful gases and solid wastes are discharged, containing various components such as h...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, in industrial production, especially in chemical enterprises, a large amount of waste gas is often discharged. This kind of waste gas contains a large amount of heat energy and volatile organic solvents that can be recycled. The current waste heat recovery device is relatively simple and cannot meet the current use requirements.
