Oil sludge and coal co-combustion device and process

Abstract

The invention discloses an oil sludge and coal co-combustion device and process, and belongs to the technical field of thermal power plant equipment. According to the oil sludge and coal co-combustiondevice and process, a combustion boiler, a stirring and mixing assembly, a smashing assembly, a lifting and conveying assembly and a co-combustion entering assemblies are included, and the bottom ofthe stirring and mixing assembly is connected to the combustion boiler. The upper end of the stirring and mixing assembly is connected with the lifting and conveying assembly, the side face of the stirring and mixing assembly is connected to the smashing assembly, and the co-combustion entering assemblies are arranged on the two sides of the smashing assembly and each comprises an oil sludge inletpiece and a coal inlet piece. According to the oil sludge and coal co-combustion device and process, uniform mixing of co-combustion can be guaranteed, meanwhile, a mixture is sorted, it is guaranteed that particles of the mixture are refined and enter the combustion boiler to be combusted, the combustion efficiency is improved, meanwhile, sorting is conducted twice through a vibration motor, fine particles are fully sorted, the situation that too many mixture particles enter a smashing box is avoided, and the co-combustion efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of thermal power plant equipment, and in particular relates to a mixed burning device and a mixed burning process of sludge and coal. Background technique [0002] With the increasingly severe energy crisis in the world today, coal-fired power plants are also facing enormous pressure. The price of coal keeps rising. The quality of coal is uneven and there are many types, which makes it impossible for thermal power plants to only burn the designed coal for the boiler. The power plant blends a certain amount of non-design coal types. If the blended coal types and proportions are appropriate, it will bring beneficial effects to the power plant, improve the combustion situation, reduce the carbon content of fly ash and pollutant emissions, and also reduce power generation costs. Improve the economic efficiency of the enterprise. However, if the understanding of blended combustion is not enough and the blending...

Problems solved by technology

However, if the understanding of blending combustion is not enough and the blending is unreasonable, it will often bring great threats to the safety and economy of the power plant, and even cause accidents such as shutdown.
