Description
Technical Field
The invention belongs to the technical field of waste gas treatment, and particularly relates to an ultra-clean discharged waste gas treatment system and an ultra-clean discharged waste gas treatment method.
Background
Traditional flare systems fall into two broad categories, elevated flare and ground flare. The diffusion influence range of the ground torch is small, the influence on the unorganized emission of a factory boundary is obvious, and the indirect supervision on the ground torch can be realized by means of the supervision on the unorganized emission of the factory boundary; the overhead torch has large heat radiation range, serious noise pollution and light pollution, is more suitable for being built in areas with rare population, has undesirable burnout rate when the flow of the torch gas is large, needs a large amount of steam for combustion supporting and has higher cost. In addition, overhead torch is located the hectometer high altitude, and difficult realization real time monitoring can't effectively supervise, and the condition that usually not natural gas directly discharges the torch takes place.
Among the prior art, waste water that waste gas recovery system and torch system produced at the operation in-process, like the waste water in torch gas condensate and the water seal jar in the branch fluid reservoir, often directly discharge into the trench and get into the sewer line, do not carry out recycle, caused the waste of water resource, increased the sewage treatment expense simultaneously, and easily caused environmental pollution.
In addition to the conventional flare system, conventional waste gas treatment technologies such as incinerator, activated carbon adsorption, UV photolysis, adsorption, etc. have certain limitations in the aspects of waste gas treatment capacity, organic waste gas concentration, load regulation ratio, etc., and these devices also need to be matched with corresponding post-treatment facilities (such as additional facilities for desulfurization and denitrification, etc.), and sometimes produce secondary pollution. Therefore, the flare system is still the best scheme for treating the waste gas with complex discharge working condition, large load change range and large flow.
With the increasing environmental requirements, the regulations and policies for exhaust emission will become more stringent.
The 'Nanjing city elevated torch environment management method' released in the Nanjing city in 2019 clearly suggests that the elevated torch should be used for emergency disposal, and cannot be used as a daily atmospheric pollution treatment measure, and the waste gas treated by the elevated torch is only the combustible gas which cannot be effectively recovered in emergency states such as process unit startup and shutdown, fire accidents and other accidents. Waste gases with too high a proportion of nitrogen, etc. must not be discharged into the flare system.
