Exhaust gas emission standard and waste gas treatment plan of rubber products


Rubber products use raw rubber (natural rubber, synthetic rubber, reclaimed rubber, etc.) as the main raw material and various compounding agents as auxiliary materials. It is used in the production enterprises of tires, motorcycle tires, bicycle tires, hoses, tapes, rubber shoes, latex products and other rubber products.

The emissions of rubber enterprises include: nitrogen oxides, sulfuric acid mist, hydrogen chloride, hydrogen fluoride, hydrogen sulfide, sulfur dioxide and other organic waste gas, which seriously pollute the atmospheric environment and affect the health of surrounding residents. Therefore, the treatment of rubber waste gas needs to be carefully considered.
Emission Standard of Pollutants for Rubber Products Industry
Several basic elements of a governance program:
Select the treatment plan according to the exhaust gas composition (whether it contains moisture, solids, oil, and the difficulty of treatment), concentration (high, low), and emission form (continuous or intermittent emission).
The following conditions are suitable for choosing the plasma high temperature ion incineration treatment plan:
High organic content, complex composition, flammable and explosive (butadiene, etc.), difficult to decompose substances such as carbon disulfide, industrial waste gas containing particulate matter, oily matter, and continuous large-dose discharge.
Such as gravure printing, offset printing, painting, chemical synthesis, petrochemical, flavor, fragrance and other industries.
In the following cases, a cyclone dust removal device needs to be added:
Industrial waste gas containing particulate matter, such as coating industry waste gas.
The following conditions need to increase the condenser:
The exhaust gas temperature exceeds 70℃ and contains a lot of moisture, so it is necessary to install a condenser.
The following situations need to increase the gas, liquid (oil) separation device:
1. Industrial waste gas containing oily substances, such as exhaust gas from waste incinerators.

2. Contains a lot of water.

The following situations need to install explosion-proof flame arrester: (natural gas explosion-proof flame arrester)
The exhaust gas contains flammable and explosive components, and the workplace has explosion-proof requirements.
High temperature plasma incineration technology:
High-temperature plasma incineration technology is a high-frequency (30KHz) high-voltage (100,000-volt) high-power power supply under specific conditions of energy-gathering discharge. The industrial waste gas rises sharply from normal temperature to a high temperature of 3,000 degrees in the reactor. Under the dual action of high temperature and high potential, the organic pollutants (VOCs) are instantly ionized and completely cracked.
After high temperature plasma incineration, the organic compounds (VOCs) in industrial waste gas are cracked into carbon, carbon dioxide, water vapor and other elemental substances.
High-temperature plasma incineration technology can treat industrial waste gas with high concentration, complex composition, flammable and explosive, containing solid and oily substances.
