Emergency treatment system and emergency treatment method for high-concentration VOCs waste gas

Abstract

The invention discloses a high-concentration VOCs waste gas emergency treatment system and an emergency treatment method, and relates to the field of VOCs waste gas emergency treatment systems.The high-concentration VOCs waste gas emergency treatment system comprises a waste gas treatment tower, the waste gas treatment tower is of a cylindrical structure and is erected on the ground, and a discharge outlet is formed in the upper end of the waste gas treatment tower; a waste gas discharge pipe for introducing waste gas into the waste gas treatment tower is arranged at the lower end of the waste gas treatment tower, the waste gas is added into the inlet cavity through the waste gas discharge pipe, and the waste gas flows upwards to the compression area through the inlet cavity, then is compressed and passes through the middle part of the bottle opening structure; particulate matters in the compressed waste gas are filtered out and discharged into the bottom of the cavity to be collected, and the treatment cost of the waste gas is saved in a manner that the particulate matters in the waste gas are compressed and discharged by utilizing kinetic energy of the waste gas.

Description

technical field [0001] The invention relates to the field of VOCs waste gas emergency treatment system, in particular to a high-concentration VOCs waste gas emergency treatment system and an emergency treatment method. Background technique [0002] Volatile organic compounds, often expressed as VOCs. According to the definition of the World Health Organization, VOCs is a general term for various organic compounds with a boiling point of 50°C to 260°C at room temperature. In my country, VOCs refer to organic compounds with a saturated vapor pressure greater than 70Pa at room temperature and a boiling point below 260°C at normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10Pa at 20°C and are volatile. [0003] VOCs are usually divided into several categories such as non-methane hydrocarbons (NMHCs for short), oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, and sulfur-containing organi...

AI Technical Summary

Problems solved by technology

[0004] At present, domestic VOCs treatment equipment is mainly based on regenerative combustion method and catalytic oxidation method, both of which require high-temperature treatment, which has great risks, is prone to secondary pollution, consumes a lot of energy, and is easily limited by the concentration and temperature of organic waste gas. Disadvantages such as incomplete treatment, and high input costs. In the process of using activated carbon to absorb waste gas, due to the high temperature of some waste gas, the activated carbon is heated at high temperature and is in the regeneration and reduction state of releasing harmful substances, which cannot completely filter the waste gas. The purpose of this is often only to filter out some large particles of impurities in the exhaust gas
