A method for generating water vapor in a coke reactivity measuring device

Abstract

The invention provides a water vapor generating method of a coke reactivity measuring device, and belongs to the technical field of chemical reactions. According to the water vapor temperature and flow needed by an experiment, the flow of distilled water is calculated, the flow of a speed regulating type peristaltic pump of a water vapor generating device is adjusted, under driving of the speed reducing type reducing peristaltic pump, the distilled water flows to a water vapor generator of an evaporating unit from a beaker through a liquid supply pipe, the water vapor generator is in a funnelshape, the distilled water moves upwards in the water vapor generator, the evaporating area of the distilled water is gradually increased, when moving to the top of the water vapor generator, the distilled water is gasified into water vapor, and the water vapor enters a quartz pipe through the water vapor generator. By precisely controlling the temperature of the experimental water vapor, the flowand the airflow stability, and the coke reactivity measuring device can be directly used for a coke solution loss reaction or other laboratory studies of the water vapor and other gases at differenttemperature and different flow.

Description

technical field

[0001] The invention belongs to the technical field of chemical reaction, in particular to a method for generating water vapor of a coke reactivity measuring device. Background technique

[0002] Coke is an indispensable raw material in blast furnace ironmaking production. Its role in blast furnace mainly includes four aspects: ①Provide heat source; ②Reductant; ③Support skeleton of blast furnace charge; ④Carburize molten iron. Among them, the supporting skeleton of coke is the most important, because it is the prerequisite for ensuring good air permeability and liquid permeability of the blast furnace charge column. However, coke will deteriorate in the blast furnace, especially in the lower part of the blast furnace, which is prone to pulverization, which will seriously deteriorate the air permeability and liquid permeability of the blast furnace, resulting in difficulties in the forward movement of the blast furnace and a reduction in the production of molt...
