Abstract

The invention provides equipment for catalytic cracking and combustion of waste rubber and plastic of a cement kiln head. The equipment comprises a pulverized coal burner, a waste fuel swirling burner, an airlock feeder, a high pressure fan, a meter feeder, a waste fuel bin, a conveyor I, a homogenizer, a meter feeding pump and a catalytic cracking oxidant storage tank. The equipment is simple, and relatively mature equipment is provided for selection; waste tires/waste plastic is used as alternative fuel, and the utilization cost is low; the equipment is high in economy and convenient for popularization; environmental pollution caused by the waste tires/waste plastic can be reduced effectively, and energy consumption and environmental pollution in the recycling and machining process of the waste tires/waste plastic are reduced, in favor of environmental protection; the invention provides new economic and practical equipment for utilizing the waste tires/waste plastic as the alternative fuel of the kiln head for cement enterprises, in favor of energy saving, emission reduction, cost decrease and benefit improvement of the cement enterprises.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to equipment for catalytically cracking and catalytically burning waste rubber and plastics at the cement kiln head of a dry process cement production line. Background technique [0002] At present, the actual production capacity of my country's cement reaches 4.5 billion tons, about 3 tons per capita, accounting for more than 60% of the world's total cement production capacity, and cement production is recognized as an industry with high energy consumption and high pollution. The inevitable trend of emission reduction. But as we all know, the core of the cement kiln clinker production system is to burn two fires, that is, one fire at the kiln head and one fire at the calciner. The firing quality of clinker depends more on the one fire at the kiln head. , because the firing temperature of ordinary silicate clinker is 1450°C, that is, the temperature of the...
