Problems solved by technology
[0002] With the development of steel wire surface cleaning technology and the requirements of environmental protection and energy saving, chemical pickling is gradually replacing electrolytic pickling. Chemical pickling requires hydrochloric acid to have a higher temperature, and hydrochloric acid is very corrosive to metal materials. The choice of heating device brings difficulties. Commonly used titanium alloy heating tube heating and Teflon steam heating have disadvantages such as high cost and poor reliability. There is no good solution in the prior art, and it is urgent to solve the problem of anti-corrosion of heating device

The invention relates to a hydrochloric acid heating device. The hydrochloric acid heating device mainly consists of a quartz tube, a heating source, a heating fixed seat and a safety protection cover, wherein the opening end of the quartz tube is provided with the heating fixed seat and the safety protection cover, the heating source is arranged in the quartz tube, the quartz tube and the heating source are fixed by the heating fixed seat, and a heating source connection end is provided with the safety protection cover. The method comprises the following steps: placing the quartz tube into hydrochloric acid, placing the heating source in the quartz tube below the liquid surface of the hydrochloric acid to prevent dry burn, the quartz tube does not have chemical reaction with hydrochloric acid and does not directly contact hydrochloric acid, the corrosion is inhibited, the heating can be realized by electrifying the heating source, the heating effect is good, the temperature is easy to control, the service life is long, and easy maintaining, safety and reliability can be realized.
Description
Technical field [0001] The invention relates to a hydrochloric acid heating method and device, belonging to the technical field of heating equipment. Background technique [0002] With the development of steel wire surface cleaning technology and the requirements of environmental protection and energy saving, chemical pickling is gradually replacing electrolytic pickling. Chemical pickling requires hydrochloric acid to have a higher temperature, and hydrochloric acid is very corrosive to metal materials. The selection of the heating device brings difficulties. The commonly used titanium alloy heating tube heating and Teflon steam heating have disadvantages such as high cost and poor reliability. There is no good solution in the prior art, and there is an urgent need to solve the problem of corrosion prevention of the heating device. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, provide a hydrochloric acid h...
