Embodiment 1

[0041] Refer to attached figure 1 , figure 2 , Figure 4 and Figure 5 As shown, the water vapor generation method of a coke reactivity measuring device in this embodiment, the water vapor generation device adopted includes an infusion unit 100, an evaporation unit 200 and a heating furnace 300, and the infusion unit 100 and the evaporation unit 200 pass through the liquid supply pipe 130 connection, the evaporation unit 200 is set in the quartz tube 310 inside the heating furnace 300 . The infusion unit 100 is used to deliver the distilled water required for the experiment, the evaporation unit 200 is used to evaporate the distilled water, and the heating furnace 300 is used to provide the temperature required for evaporation. The heating furnace 300 is provided with a quartz tube, and the top of the heating furnace 300 is provided with a scale A weighing balance 330 , a sample cage 340 is suspended from the lower part of the weighing balance 330 , and the steam generator...

Embodiment 2

[0058] Refer to attached figure 1 , image 3 , Figure 4 and Figure 5 As shown, the water vapor generation method of a coke reactivity measuring device in this embodiment, the experimental device adopted is basically the same as that of embodiment 1, the difference of the device is that the lower stabilizing plate 230 is not fixedly arranged on the water vapor Steam generator 210, that is, the lower stabilizing plate 230 can float up and down in the steam generator 210 with the height of the liquid level; the lower end of the lower stabilizing plate 230 is not provided with a liquid level detection mechanism 240, but the lower steady The upper end of the flow plate 230 is provided with a contact probe 250, and the contact probe 250 is arranged on the side wall of the steam generator 210. When the lower flow plate 230 floats up with the rise of the liquid level, it will touch the contact probe. 250. At this time, reduce the power of the speed-regulating peristaltic pump 120...

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...
