Problems solved by technology

Commonly used waste incinerator trays are heat-resistant cast steel, but in actual waste incineration applications, after a long period of use at high temperatures, they are easily corroded by acidic substances generated during the heating process of waste, and the price is relatively high. Its own weight is large, the beam bearing capacity is high, and the power consumption is increased, which greatly affects its performance

Abstract

The present invention discloses a non-metal material tray for a garbage pyrolysis furnace rotating bed. The non-metal material tray is characterized by comprising an inorganic powder material and an additive, wherein the inorganic powder material comprises, by weight, 60-70% of silicon carbide, 10-30% of silicon powder, 5-10% of silicon nitride, 2-8% of alumina micro-powder, 2-5% of silicon dioxide, 1.0-2.5% of calcium oxide, and 1.0-2.5% of boron nitride. According to the present invention, the material tray achieves the performances of garbage acid substance corrosion resistance, erosion resistance, wear resistance, strong thermal shock resistance, good thermal conductivity, low expansion coefficient, light weight, low energy consumption and the like are achieved when the garbage pyrolysis furnace rotating bed treats garbage at the high temperature, the service life of the garbage pyrolysis furnace rotating bed is ensured, and a series problems caused by garbage pyrolysis furnace rotating bed material tray cracking deformation, corrosion and wear and the like are avoided.

Description

Technical field [0001] The present invention involves garbage heat dissolving furnaces, especially a kind of garbage thermal solution furnace rotating bed with high strength, abrasion resistance, high temperature resistance, corrosion resistance, good thermal conductivity, strong heat shock resistance, light quality and long service life.The garbage thermal decompction rotation bed is used for non -metal disk and its preparation method. Background technique [0002] Urban domestic garbage treatment is one of the main environmental issues facing countries around the world, and it is also an environmental problem that is currently prominent in my country.With the rapid development of my country's economy, a large increase in the urban population, the increasing expansion of cities and the continuous improvement of the living standards of the people, the increase in domestic waste production has increased year by year, and it will inevitably prevent real estate emissions.After 1995,...
