Purification of flue gas by lime suspension
For the wet desulphurisation of flue gas, it is passed through an absorber (scrubber). The lime suspension offered in the absorber (limestone or lime milk) reacts with the sulphur dioxide from the flue gas. The better the mass transfer, the more effective the desulphurisation is.
Simultaneously with the absorption, the flue gas is saturated with water vapour. The so-called "clean gas" is usually discharged via a wet chimney or cooling tower. The water thus lost for the process must be replaced. The lime slurry pumped in circulation is kept chemically active by repeatedly draining a saturated partial flow and replacing it with new reactive suspension. The drained part flow contains gypsum, which - simplified - is a reaction product of lime and sulphur and can be marketed after dewatering (e.g. for gypsum walls in the construction industry).
Special ceramic nozzles are used to inject the lime suspension into the absorber. These nozzles form many small droplets from the pumped suspension and thus a correspondingly large reaction surface for good mass transfer. The ceramic material permits long service life despite the fact that lime suspension with gypsum content has abrasive properties. In the design we attach great importance to free cross-sections, so that smaller impurities in the suspension cannot set the nozzles. For economical operation, these nozzles can be adapted to the highest efficiency range of the pump. A nozzle can be specified for (almost) every process engineering challenge. In addition to full-cone and hollow-cone nozzles in various spray angles and flow rates, the ZPC nozzle with patented twist compensation is also available.
The absorption zone consists of several levels of nozzles and a horizontally installed droplet separator system, in order to return the fine droplets carried along in the gas stream to the process. With our high performance droplet separators you can increase the efficiency of your plant.
The solids in the suspension can lead to deposits, e.g. in the droplet separator, in the inlet duct or on pipes, which can lead to problems in operation. Since water is always withdrawn from the circuit through evaporation, water must be fed into the absorber, which can and should be used for cleaning. ZPC tongue nozzles have proven themselves for cleaning the flue gas inlet. ZPC full cone nozzles are usually used for cleaning the droplet separators.
Plastics (e.g. for pipelines) and rubber (e.g. gaskets, rubber linings, etc.) are often used in an absorber whose temperature resistance is lower than the temperature of the uncooled flue gas. Normally, the suspension pumped in a circuit cools the flue gas sufficiently, but if, for example, the feed pump is suspended, the plastics and rubbers could be destroyed. Small special-alloy metal nozzles have proven their worth here, which take over cooling during this time and thus protect the investment of the flue gas desulphurisation plant.
As a professional nozzle supplier for flue gas desulphuration system, we have rich experience In spray application and seperation. We are able to provide a variety of products with high reliable Performance and strong technical supports as well as perfect after-service.
Spiral nozzle is one of the most unique nozzle, with the spiralling gradient body, the limestone slurry Is constantly tangent with th spiral line and then changing direction and cutting into co-axle cone with very free flow throught the body till exit. Even under low operation pressure, it still has A high absorption efficiency. Therefore it is widely recognized by in a desulfuration system.
We are able to develop solutions specific to each individual customer according to your requirement.

Company Introduction:
We introduce advancd technology from abroad, and we own two patents now: Patent furnace body of the vacuum induction furnace, patent furnace body of the SiC products high temperature carbon tube sintering furnace. The leading product of the company is SiC desulfurzation nozzles. It is the key component of the sulfur removal assembly in the fired power plants, volume boilers. The nozzles have many excellent qualities, such as high-intensity, high hardness, strong corrosion and severe and abrasion resistance, long service life and so on. There are various kinds of nozzles, including spiral nozzles, eddy current linear cutting nozzles and special-shaped nozzles.
The company also produces burner, roller, beam, radiant tube, rapid cooling tube, thermocouple protecting tube, crucilble, chemical pipes and other special-shaped products. The products are widely used in consturction ceramics, domestic ceramics, industrial kilns, environmental protection of the power plant, paper manufacture, machinery and many other fields. The radiant tube are widely used in the forging steel company. These products fill the domestic emptiness in many fileds.
The products have already batch exported to Malaysia, Japan, Vietam, Pakistan, Southe Africa, Australia, South Korea and many other countries and regions. Base on the strength of the professional work team, scientific management, superior facilities, and good quality products, we are seeking to be the first level reaction sintered silicon carbide manufacturer in the world. Taking the management theory of exploiting innovation, integrity management and mutual benefit, we sincerely hope to establish a long term and stable business cooperation relation with clients at home and abroad.
