Description

Cooling device for inhibiting scaling of two-in-one graphite synthesis furnace Technical Field The utility model belongs to the technical field of cooling, and particularly relates to a scaling-inhibiting cooling device of a two-in-one graphite synthesis furnace. Background At present, the production of hydrogen chloride gas mainly adopts a two-in-one steam type graphite synthesis furnace. During normal production, it is important to operate and control the graphite synthesis furnace. The method is characterized in that the control of the chlorine-hydrogen ratio is realized mainly by precisely adjusting the amounts of chlorine and hydrogen entering a synthesis furnace, and the inlet air flow of the chlorine and the hydrogen is finely adjusted to ensure that the chlorine and the hydrogen reach a proper ratio, thereby ensuring the efficient synthesis of the hydrogen chloride gas. The two-in-one graphite synthesis furnace generates a large amount of heat in the operation process, and in order to maintain stable operation temperature, circulating water is adopted for heat exchange and cooling operation. The circulating water continuously flows in the cooling system of the synthesis furnace, takes away heat and plays an effective cooling role. The circulating water cooling heat exchange mode adopted by the two-in-one graphite synthesis furnace has a certain risk, and the water quality of the circulating water possibly contains more impurities, and the impurities can continuously flow in the system along with the circulating water. When the synthesis furnace is operated for a long period of time, these impurities gradually accumulate and adhere to heat exchange members inside the synthesis furnace. This build-up process is a progressive process that may initially have less impact, but over time gradually blocks the heat exchange channels inside the synthesis furnace, reducing the heat exchange effect. Once severe, even more serious damage to the synthesis furnace can occur, with a greater risk of economic loss and production interruption. Therefore, a novel cooling device for inhibiting scaling of the two-in-one graphite synthesis furnace is needed.
