Chilling split type dry coal powder gasifying furnace

Abstract

The invention belongs to the fields of coal chemical industry and coke gasification, relates to chemical equipment techniques and particularly relates to a chilling split type dry coal powder gasifying furnace. The chilling split type dry coal powder gasifying furnace comprises a gasifying furnace hearth, a burner and a chilling chamber, wherein the gasifying furnace hearth comprises a shell, a hearth inlet, a hearth outlet, a combustion chamber and a chilling wall; the hearth inlet is connected with the burner; the hearth outlet is connected with a chilling chamber inlet big flange; the burner comprises a central oxygen channel, a dry coal powder channel, a gasifying agent channel, a fuel gas channel, a pursing channel, a water jacket water inlet, a water jacket water outlet and a burner big flange; the burner big flange is connected with the hearth inlet; and the burner is of a four-runner design, and the four runners of the burner are sequentially the fuel gas channel, the central oxygen channel, the dry coal powder channel and the gasifying agent channel from inside to outside. According to the chilling split type dry coal powder gasifying furnace, high-temperature water coal gas can be chilled, and meanwhile, the gasified furnace slag and the water coal gas are effectively separated, so that the washing separation effect and the heat exchange effect are good, the equipment is compact and reliable, the manufacturing cost is low, and the water coal gas can be obtained through conversion.

Description

technical field [0001] The invention belongs to the field of coal chemical industry and coke gasification and relates to chemical equipment technology, in particular to a chilled split type dry coal powder gasification furnace. Background technique [0002] The gasification combustion chamber and the quenching chamber of the dry pulverized coal gasifier in the traditional quenching process are integrated, and the height ratio of the quenching chamber to the gasification combustion chamber is usually greater than 1:1. Therefore, the main building of the gasification device is relatively high. If it is longer than 56 meters, the cost of equipment and civil engineering will be higher, resulting in a larger investment in pulverized coal gasification, which will bring greater financial pressure to investors and affect the economics of the project. In addition, the quenching ring set in the traditional chilling chamber has high material requirements, is difficult to process, and n...

Problems solved by technology

[0002] The gasification combustion chamber and the quenching chamber of the dry pulverized coal gasifier in the traditional quenching process are integrated, and the height ratio of the quenching chamber to the gasification combustion chamber is usually greater than 1:1. If it is larger than 56 meters, the cost of equipment and civil engineering will be higher, resulting in a larger investment in pulverized coal gasification, which will bring greater financial pressure to investors and affect the economics of the project

In addition, the cooling ring set in the traditional cooling chamber has high material requirements, difficult processing and needs to be replaced regularly. The replacement project requires a large amount of work and consumes increased manpower and material resources.
