Description
Technical field
Technical field of waste gas treatment is the utility model is related to, more particularly, to a kind of industrial VOCs exhaust treatment systems.
Background technology
Field is administered in industrial waste gas VOCs (volatile organic compounds, volatile organic matter), at present
The most commonly used method is heating power oxidizing process, i.e., VOCs complete oxidations in waste gas is decomposed into two under high temperature (more than 760 DEG C)
Carbonoxide and water, to reach the purpose of purification waste gas.

It is most important processing mode that thermal oxidation furnace, which carries out processing to industrial waste gas,.RTO common structure type has at present：Two Room
RTO, three Room RTO, rotary RTO etc..
Two regenerator should be comprised at least in RTO, regenerator is interior by heat storage, and its handling process is substantially：It is processed
High-temperature gas flow through heat storage, heat storage is heated up, this is " accumulation of heat "；Untreated waste gas flows through the heat storage of high temperature,
Absorb the heat in heat storage and heat up, this " heat release ".Each regenerator undergoes the programs such as accumulation of heat-heat release successively, goes round and begins again,
Continuous work." heat release " state：Low-temperature airflow flows through heat storage, and gas flow temperature gradually rises；" accumulation of heat " state：High temperature gas flow stream
Through heat storage, gas flow temperature gradually reduces.VOCs gases in the heat storage of " heat release " state its low-temperature range are not due to reaching
Do not decomposed to oxidizing temperature, therefore when heat storage is directly converted to " accumulation of heat " by " heat release ", these are undecomposed
VOCs can be discharged to outside after state switching.For this problem, two traditional Room RTO, without effective mitigation strategy, therefore two
Room RTO purifying rate typically can only achieve 95%, can not all reach discharge standard in many cases.And it is to alleviate this problem to grind
The three Room RTO issued and rotary RTO, add the process of a cleaning before State Transferring, and its purifying rate can reach
99%.But relative to two Room RTO are complicated, control program is cumbersome, cost also has significantly to be increased three Room RTO and rotary RTO
Add.
