VOCs treatment device and method in ship construction

Abstract

The invention provides a VOCs treatment device and method in ship construction. The VOCs treatment device comprises a first VOCs standard adsorption and desorption unit, a second VOCs standard adsorption and desorption unit, an intelligent VOCs tail end treatment equipment management and control platform, a VOCs concentration sensing switching valve module, a VOCs unorganized discharging and collecting equipment desorption standard interface module, a zeolite rotating wheel and an RTO thermal decomposition treatment unit. According to the VOCs treatment device and method in ship construction, centralization, modularization and intelligentization of VOCs tail end treatment in ship construction are achieved, the treatment cost is greatly reduced, and the treatment optimization capacity is improved.

Description

technical field [0001] The invention relates to the technical field of volatile organic compounds (Volatile Organic Compounds, VOCs) treatment, in particular to a VOCs treatment device and method in shipbuilding. Background technique [0002] The common types of VOCs produced in the ship coating process include benzene, xylene, tetrachloroethane, isocyanate and non-methane total hydrocarbons. These substances are organic compounds that participate in atmospheric photochemical reactions, and are important precursors for the formation of ozone (O3) and fine particle (PM2.5) pollution, causing huge environmental pollution and bringing inconvenience to people's daily life and daily travel. . [0003] Ship painting is a systematic project integrating design, technology, technology and management, which runs through the entire process of ship construction. Since marine coatings generally use VOCs such as toluene, xylene, and alcohols as organic solvents, the above substances are...

AI Technical Summary

Problems solved by technology

The above scheme effectively solves the problem of VOCs organized emission, but its operating cost has been high, especially the cost of burning liquefied natural gas (Liquefied Natural Gas, LNG) to maintain the thermal decomposition temperature in the RTO constitutes VOCs organized emission The main part of governance costs

At the same time, there is no mature solution for VOCs unorganized emission control, and it is difficult to achieve a balance in terms of initial investment, operating cost, emission reduction effect, and operational stability.
