Problems solved by technology

[0003] Due to the high carbon content of a large amount of fly ash, it cannot be fully and rationally utilized without decarbonization treatment
When fly ash is mixed into concrete as an admixture, the higher the carbon content of fly ash, the greater the amount of water required for concrete, resulting in an increase in the water-binder ratio, which seriously affects the full play of the fly ash effect, and Excessive loss on ignition of fly ash will seriously affect the control of air content in concrete

Abstract

The invention discloses a high-voltage electric separator applicable to separation of pulverized fuel ash. The high-voltage electric separator comprises a rack, wherein the rack is dived into a feeding zone, separation zones and a material receiving zone in sequence in a material separation direction; a vibration cloth hopper and a riffle are arranged in the feeding zone; the vibration cloth hopper and the riffle are mounted at the top of the rack; the riffle is fixed on the vibration cloth hopper; two separation zones are arranged in parallel and located under the vibration cloth hopper. The high-voltage electric separator applicable to separation of the pulverized fuel ash has the advantages of compact structure, little pollution and capability of continuously and uniformly feeding.

Description

technical field [0001] The invention relates to equipment for separating fly ash, in particular to a high-voltage electric separator for separating fly ash. Background technique [0002] Fly ash is a kind of industrial waste discharged from pulverized coal boilers in thermal power plants. The powder collected from the flue gas after coal combustion is called fly ash. China uses coal as the main energy source, with an annual coal consumption of more than 400 million tons. Fly ash is one of the industrial wastes with a large discharge volume in my country. The comprehensive utilization of fly ash is an important means to solve the contradiction between environmental pollution and resource shortage in my country's electric power production, and it is also one of the tasks faced by electric power production. After development and research, fly ash has been widely used in various departments such as construction engineering, building materials, and water conservancy. In order t...
