Has SNCR\SCR flue gas denitration technology. Curing dry, semi-dry, wet flue gas deacidification technology, bag dust removal, electrostatic dust removal and other flue gas treatment technologies, all emission indicators fully meet the current EU standards, and can be customized for the "near zero emissions" program.

Flow chart

1. Reaction tower

Combined with CFD simulation technology, the temperature field and flow field in the reaction tower are simulated and optimized. After the optimization in the tower, the lime consumption is large, the lime slurry is easy to hang, the reaction efficiency is low, and the water content of the reaction product is solved. Large easy to cause blockage and other problems, also changed the ash accumulation phenomenon in the reaction tower, the maintenance time is shortened, to meet the optimal reaction conditions and efficient and reliable deacidification effect, effectively improve the deacidification rate;

2, rotary atomizer

The function of the rotary atomizer is to atomize the lime slurry entering the deacidification tower into fine particles, which are fully contacted with the flue gas to remove the acidic substances in the flue gas. The integrated rotary atomizer has the following advantages: the atomization disk has a high rotation speed (12,000 rpm), and the lime slurry can be sufficiently atomized into fine particles of 30-100 micrometers, the gas-liquid contact area is increased, the reaction speed is enhanced, and the acid removal efficiency is improved. The unique open atomizing disk design and high speed rotation of the nebulizer ensure that solid deposits and blockages do not occur on the atomizing disk.

3, atomizing disk

Atomizing disk: The atomizing disk is a key component in the treatment of waste incineration flue gas. It works continuously in high speed, strong acid, strong alkali, high temperature and abrasive environment. The research on atomization disk for waste incineration power generation involves many fields and the manufacturing difficulty Large, high precision requirements, short service life and high price. The atomization plate developed by our company has been used or even better than the import level by Suzhou, Changzhou and Zhenjiang. The quality is stable and the cost is obviously lower than Imported products, the project life cycle reaches 1 year.

5, SNCR system


SNCR means that in the absence of a catalyst, the reducing agent selectively reacts with nitrogen oxides in the flue gas to form nitrogen and water, thereby removing nitrogen oxides from the flue gas.

SNCR introduces German Martin technology, the system is simple, the ammonia metering is accurate, the atomization performance is excellent, the temperature measurement control mode is more advanced, the ammonia water consumption is less, and the denitration effect can reach more than 60%.

Spray gun: good atomization effect, the main body is made of stainless steel 316Ti, the corrosion resistance is very strong, the nozzle adopts high temperature resistance 31Os, the nozzle adopts long tube type design is simple, easy to replace, the front end damage of the nozzle does not affect the spraying effect, the theoretical life is longer, all connections Adopted, convenient.

7, fly ash processing system

The fly ash produced by domestic garbage belongs to hazardous waste and needs to be treated in a stable manner before it can be transported. Under this premise, it is continuously researched and developed to realize the self-construction capability of waste incineration fly ash stabilization treatment system design and equipment supply.

       Process characteristics

1 The new chelating agent is used to stabilize the heavy metals in the fly ash. After the test meets the national standards, it enters the domestic waste landfill, and the treatment cost is low and the effect is good.
2 The fly ash and the chelating agent are stirred by a new type of mixer. The inner surface of the mixer is made of alloy steel and mirror-finished (or lining the PTFE plate) to effectively solve the problem of material adhesion.
A reduction in the gap between the blade and the wall results in a problem with the device jam.
3 The chelating agent is added to the mixer through the atomizing nozzle to strengthen the mixing of the fly ash and the water-forming chelating agent. The agent is used less, and the stabilizing efficiency is high.
4 After the stabilization, the fly ash is granulated, the molding rate is high, and the strength is large, which can greatly improve the utilization rate of the landfill storage capacity.
5 The fly ash stabilization system is well sealed and reliable measures are taken to reduce dust and improve the production environment.
6 Independent research and development control system with high degree of automation, precise control and flexible operation.

8. Emission standards

The waste gas emission standard GB18485-2001, EU 2000 standard and GB18485-2014 standard of waste incineration plant are shown in Table 1.

Note: 1) The standard limits specified in this table are based on the reference value of 11% O2 dry flue gas in the standard state.

2) The maximum blackness time of the smoke shall not exceed 5 minutes in any 1h.

3) HCl, HF, SOX, NOX, and CO are the hourly average values in GB18485-2001, while the EU 1992 and EU2000/76/EC are daily averages. The remaining contaminants were measured for mean.
