Super wear-resistant ceramic lining plate

Abstract

The invention discloses a super wear-resistant ceramic lining plate. A cuboidal lining plate is 2-3 cm high, 15-16 cm long and 7-8 cm wide, wherein the upper and bottom edge angles of the cuboidal lining plate are chamfers which are 45 degrees and 1-2 mm long; a vertically through round hole is formed in the middle of the ceramic lining plate, and is a welding hole through which the ceramic lining plate can be firmly welded to equipment. The super wear-resistant ceramic lining plate has the advantages of being firm, durable, low in separation rate, close in connection, resistant in high temperature, high in wear resistance, long in service life and the like.

Description

technical field [0001] The invention relates to a super wear-resistant ceramic lining board, in particular to a kind of chamfered upper and bottom edges and corners, a round hole penetrating up and down in the middle of the ceramic lining board, and a semicircular hole in the upper part of the lining board. Ultra-wear-resistant ceramic liner for pure low-temperature waste heat power generation in cement kiln with protrusions. Background technique [0002] Cement kiln pure low-temperature waste heat power generation is a technology that converts excess heat energy in the cement production process into electrical energy. Waste heat power generation is not only energy-saving, but also conducive to environmental protection. In the dry process cement production line, the exhaust gas discharged from the kiln tail preheater is installed in the kiln tail waste heat boiler, and the waste gas discharged from the kiln head clinker cooler is used to set up the kiln head waste heat boile...

AI Technical Summary

Problems solved by technology

In the dry process cement production line, the exhaust gas discharged from the kiln tail preheater is installed in the kiln tail waste heat boiler, and the waste gas discharged from the kiln head clinker cooler is used to set up the kiln head waste heat boiler. The superheated steam generated by the four waste heat boilers is supplied to the steam turbine for power generation. To achieve the purpose of comprehensive utilization, energy saving and environmental protection; the pressure used is 0.69-1.25Mpa, the temperature is 280-340°C, and the exhaust gas volume at the outlet is as high as 82000-180000m 3 / h, the temperature is 90-360 ℃, and the particle size of the exhaust gas is large, which will cause severe erosion and wear to the waste heat boiler and various pipes. At present, the pure low-temperature waste heat power generation system uses wear-resistant castables. The castable is smeared and bonded to the inner wall of the pure low-temperature waste heat power generation system. It is easy to fall off, wear and corrode under the impact and corrosion of steam, high air volume, and clinker particles. It needs to be repaired or replaced frequently to make the whole pure low-temperature waste heat The cost of the power generation system increases and the service life decreases
