Problems solved by technology

Traditional deoiling furnaces are generally made by renovating ordinary boilers. During the process of deoiling and burning waste petroleum catalysts, this kind of deoiling furnace cannot withstand the high temperature generated during catalyst combustion, which often leads to furnace body, grate and slag removal. Machine deformation, and can not meet the deoiling staged combustion requirements in the waste petro

Abstract

The invention discloses a de-oiling furnace for waste oil catalyst, comprising a furnace body; the furnace body is provided with a material inlet and a material outlet; a furnace grate for sending material is disposed in the furnace body; wherein the material inlet and the material outlet are both provided with a cooling device; and a pre-heating chamber, a burning chamber and a cooling chamber are orderly arranged between the material inlet and the material outlet; a firebrick layer is set in the burning chamber; and the furnace wall of the burning chamber is provided with a ventilation door connected with a ventilation room; and the end part of the furnace grate is further provided with a slag remover; a water heating pot cylinder is disposed in the furnace above the burning chamber; the water heating pot cylinder is provided with a drainage pipeline. The invention is featured in simple structure and smart design; the oil, sulfur and carbon compound are removed from the waste oil catalyst by the way of burning; and the heat produced by waste heat is used for heating the media, so as to supply industrial production or other occasions which need high-temperature media.

Description

technical field [0001] The invention relates to a deoiling furnace, in particular to a waste petroleum catalyst deoiling furnace. Background technique [0002] In the production process of petroleum chemical industry, some waste catalysts will be produced. When these waste catalysts are burned, a deoiling furnace is required. Traditional deoiling furnaces are generally made by renovating ordinary boilers. During the process of deoiling and burning waste petroleum catalysts, this kind of deoiling furnace cannot withstand the high temperature generated during catalyst combustion, which often leads to furnace body, grate and slag removal. Machine deformation, and can not meet the deoiling staged combustion requirements in the waste petroleum catalyst treatment process, the waste petroleum catalyst after the deoiling furnace treatment, sulfur and carbon and other impurities are not completely removed, and can not achieve the catalyst Combustion deoiling, desulfurization, and de...
