Abstract

The invention discloses an industrial emission volatile organic compounds (VOCs) tail gas on-site detecting evaluation device and a method, and belongs to the technical field of environment protection and air pollution control. The evaluation device is characterized by comprising a pre-treatment device, a catalytic combustion device, an adsorption/desorption device, a heat coupling device, a solvent separating device, an on-line analysis device and pipelines. The pre-treatment device comprises a filter, a surface air cooler, a booster fan and a gas mass flow meter. The catalytic combustion device comprises a preheating pipe and a reacting pipe. The adsorption/desorption device comprises an adsorption pipe A, an adsorption pipe B, a steam heater, a steam pocket and a circulating metering pump. The heat coupling device comprises a filter and a heat coupler. By the device and method disclosed by the invention, working conditions of enterprise tail gases are directly evaluated and researched in situ; according to the analysis evaluation result, the VOCs treatment technology which is most suitable for the working conditions of the enterprise is selected; the present most troubling technical problem on the aspect of treating the enterprise gases with VOCs waste gas emission is solved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and air pollution control, and in particular relates to an on-site detection and evaluation device and method for industrial VOCs tail gas emissions. Background technique [0002] At present, industrial organic waste gas has become one of the main pollution sources in my country's cities. Most of the VOCs contained in industrial organic waste gas are toxic, harmful, and have certain carcinogenicity; participate in photochemical reactions, form photochemical smog, or produce secondary organic aerosols, Cause large areas of air "smog" in urban areas, some of which can destroy the ozone layer. In recent years, the prevention and control of VOCs has been taken as a key task of environmental protection from the country to all provinces and regions. Therefore, the environmental protection treatment of industrial VOCS waste gas is imminent and the situation is grim. [0003] So far, VOCs...
