Industry Characteristics of the Paint Coating Workshop's Exhaust Treatment Solution:

The paint spraying industry utilizes different organic solvents due to variations in oil and gas types and processes, resulting in diverse compositions and characteristics of waste gases. Some waste gases have fewer components, while others are highly complex; some contain higher concentrations of specific components, and others have similar concentrations. Based on the varying compositions and concentration distributions of the waste gases, treatment solutions are divided into two types: recovery and destruction.

Common Processing Methods:

1. The recycling solutions mainly include condensation recovery, activated carbon adsorption/desorption, zeolite molecular sieve adsorption, or adsorption methods.

2. The destruction plan mainly includes catalytic combustion units (RCO), regenerative thermal oxidizers (RTO), and low-temperature plasma.

Several fundamental factors are considered when selecting an exhaust gas treatment solution for a paint workshop:

Based on the composition of exhaust gases (presence of moisture, solid matter, oily substances, and ease of treatment), concentration (high, low), and emission form (continuous or intermittent emissions), select the appropriate treatment solution.

The following conditions are suitable for choosing the isothermal ionization incineration treatment solution:

High in organic content, complex in composition, flammable and explosive (butadiene, etc.), containing sulfur dioxide and other non-degradable substances, industrial waste gas with particulate matter and oily substances, emitted continuously in large doses.

industries such as gravure printing, offset printing, coating, chemical synthesis, petrochemicals, and perfumes and fragrances.

The following conditions require the installation of a cyclone dust collector:

Industrial waste gases containing particulates, such as paint industry emissions.

Painting Workshop Emission Treatment Solution: High-Temperature Plasma Combustion Technology

The high-temperature plasma incineration technology involves the use of a high-frequency (30 kHz) high-voltage (100 kV) high-power power supply to discharge energy under specific conditions, generating a plasma gas flow at a high temperature of 3000°C.

Unprocessed gases are compressed and subjected to high-voltage discharge within the reactor, transforming into high-temperature plasma. During the process, the gases rapidly escalate from room temperature to an extreme heat of 3,000 degrees, causing the reactor pressure to rise significantly. Consequently, the gas volume expands dramatically, completing the thermal decomposition of materials in a very short period of time.

After high-temperature ionization incineration, the long-chain organic molecules in the waste gas are decomposed into elemental atoms. The main components of the waste gas emitted by the treatment equipment are carbon dioxide and water vapor.
