Ceramic honeycomb production line denitration introduction

Oxynitride is one of main atmospheric pollutant, the source mainly from power plant, traffic sector and industrial sector, according to the statistic, the oxynitirde emission from power plant account of *0% of total country emission.It bring a series of problem such as increasing serious of haze weather, acid rain and so on. It’s very urgent for power plant waste gas denitration at present,

The denitration technology mainly includes selective catalytic production (SCR), selective non catalytic reduction (SNCR) and SCR combine SNCR (SCR-SNCR). SCR characterized by high denitration efficiency, sophisticated technology and the most widely application area, it is the mainstay denitration technology now in the world. The core technology of SCR is catalyst carrier production, due to China oxynitride emission control is still at an early stage, the core equipment of catalyst carrier making is long term depend on import from developed countries. For breaking the monopoly of foreign technology, after one years of trial and modification, Xiangtan Weida Electrical and Machinery Manufacturer Co.,LTD have developed complete ceramic honeycomb catalyst carrier equipments based on the core equipment of large pressure 4 shaft ceramic honeycomb extruder on ***9, per filed operation in Shandong, Jiangsu ,Beijing, it have performance achieved aboard advanced equipments level. Now, almost all of Chinese ceramic honeycomb manufacturer use our machines.

According formula batching Ti*2 and other additives, then add water into R*9 intensive mixer for stirring, after the primary stirring and mixing, use special pre-extruder for filter and extruding, Then put the extruded blank to TCJ**0 powerful ceramic honeycomb vacuum extruder for continuous forming to the long green body, and the green body is cut by automatic cutting machine, then carried to dry car by manipulator, through Multi-channel high temperature dryer drying, it is sintered in mesh band low temperature electrical kiln. The process as below:

Batching→R*9 intensive mixer high speed mixing→pre-extruding→forming→auto cutting→mechanical manipulator loading→mesh band tunnel kiln sintering
