Introduction to the Toy Factory Industry

In general, children's toys are designed and manufactured for a specific age group of children and their characteristics are related to their age and stage of intelligence. The use of children's toys is predicated on a certain level of adaptability. In our country, the age of children is limited to 14 years. As a children's toy, it possesses a key factor that it must be able to attract the attention of children. This requires the toy to have bright colours, rich sounds and be easy to handle. Common children's toys include wooden toys, metal toys, cloth and plush toys, etc. In terms of their functions, the most popular toys among parents are those that develop intelligence.

Toy factory paint pollution hazards

Toy factories are the biggest hazard of pollution is from the colour of the paint job, because the toy colour using more types, usually lies in the paint raw materials and curing agents, solvents such as mixing and blending in the use of the process of generating volatile organic compounds. Common toys spray paint is usually used manually or electrophoretic paint spraying technology, volatile organic compounds if not treated, will bring serious pollution to the surrounding environment, but also on the post staff have certain hazards.

Toy factory paint treatment programme overview

For the toy factory paint VOCs treatment technology, now in line with environmental emission requirements, and play a role in reducing costs and efficiency of the treatment technology, is the use of combustion method of treatment technology is more economical and energy-saving and effective. The use of wet jet washing (multi-pipe) + dry filter + wind reduction and thickening + catalytic combustion combination of governance, governance can meet the emission requirements of standards!

Toy factory paint waste gas treatment process flow

Wet jet washing (multi-tube) + dry filtration + zeolite rotor adsorption concentration + catalytic combustion process (integrated system) process treatment. Organic waste gas is collected through the pipeline, and enters the pretreatment wet jet tower to remove paint dew, acidity and particles of purification. After purification, the gas is introduced into the dry filter to remove particles and zeolite adsorption of hazardous substances, and the organic waste gas is then sent to the zeolite adsorption bed device, and the VOCs in the waste gas is absorbed by the zeolite and then discharged to the atmosphere in compliance with the standards. When the zeolite adsorption bed is saturated by electric heating at high temperature (100-180 ℃ C) desorption of VOCs substances, desorption of high concentrations of organic waste gas directly into the catalytic combustion co, through the accelerated oxidation of high concentrations of waste gas by precious metals, in ( 250-380 ℃) high temperature purification and oxidation of harmless carbon dioxide (CO2) and water vapour (H20) and discharge to the atmosphere to meet the standards.

Other treatment process technology

Low concentration of small air volume toy factory paint exhaust can be used: spray tower, uv photolysis purifier, activated carbon adsorption and other single or multiple combinations of processes for treatment;

High concentration of small air volume toy factory paint exhaust can be used: pretreatment + zeolite molecular sieve + catalytic combustion, pretreatment + zeolite molecular sieve + RTO thermal storage incinerator, a single catalytic combustion device or a single RTO thermal storage incinerator and so on;

High concentration and large air volume toy factory paint exhaust can be used: pretreatment + zeolite rotor concentration + catalytic combustion or pretreatment + zeolite rotor concentration + RTO thermal storage incinerator and so on.
