Description
Technical Field
The invention provides a method for quickly cleaning and removing attachments such as iron oxide slag and the like on the wall of a quartz combustion tube of an infrared carbon-sulfur analyzer, belongs to the field of ferrous metallurgy analysis, and particularly relates to a method for cleaning the quartz combustion tube of the infrared carbon-sulfur analyzer.
Background
In recent years, with the development of high-frequency infrared carbon and sulfur analyzers, the high-frequency infrared carbon and sulfur analyzers are widely applied to rapid, accurate, reliable and practical analysis. The analysis process comprises the following steps: all C, S in the sample was rapidly and completely converted to CO2 and SO2 by using a high frequency furnace and a certain amount of flux, and oxygen was charged into the gas chamber, and then the total amount of the absorbed light intensity was calculated by measuring the infrared light intensity after absorption, and the data was processed to show the percentage content (mass percentage) of C, S. When a mineral sample is combusted in a high-frequency furnace, a high-temperature resistant quartz tube is generally adopted as a combustion tube of the sample, and the deposits such as iron oxide slag and the like generated along with the high-temperature combustion of the mineral sample are attached to the wall of the quartz tube, so that the stability and the accuracy of an analysis result are influenced, and the deposits such as the iron oxide slag and the like in the quartz tube need to be cleaned and removed. The usual cleaning method is to put the quartz tube into a beaker containing 1:1 hydrochloric acid (the quartz tube is totally immersed by the hydrochloric acid) and boil for 30-60 minutes, then take out the quartz tube from the beaker and repeatedly rinse and dry the quartz tube by deionized water for use. The method has long time, is unsafe, pollutes the environment and damages the physical health of a laboratory technician.
Disclosure of Invention
In order to solve the problem of cleaning, the invention provides a method for cleaning a quartz combustion tube of an infrared carbon-sulfur analyzer, which realizes rapid, safe and environment-friendly detection without damaging the body health of personnel, shortens C, S element analysis time, reduces labor intensity of workers and accelerates the timeliness of C, S element analysis samples.
The invention adopts the technical scheme that a method for cleaning a quartz combustion tube of an infrared carbon-sulfur analyzer,
1) selecting the voltage of 220-240V, the power of 50W, the ultrasonic frequency of 40000Hz, and the capacity of 2L: 2L; inner groove size: 155 x 140 x 100mm ultrasonic cleaner;
2) placing a plastic film sleeve in the ultrasonic cleaning tank, adding 30% hydrochloric acid into the cleaning tank with the plastic film sleeve, wherein the liquid level of the cleaning tank is over the quartz combustion tube;
3) adding 30% hydrochloric acid into a cleaning tank with a plastic film sleeve, enabling the liquid level to submerge a quartz combustion tube, starting an ultrasonic cleaning machine to clean, taking out after 15min of cleaning, repeatedly washing and drying with deionized water, and cleaning and removing attachments on the inner wall of the quartz combustion tube.
Ultrasonic cleaning is based on alternating shock waves and cavitation of ultrasonic frequency vibrations in a liquid. In ultrasonic cleaning, the transducer converts the electric energy provided by the power supply into ultrasonic mechanical vibration, and transmits the vibration to the cleaning liquid, when the sound wave in the liquid is transmitted, cavitation phenomenon can be generated, cavitation nuclei generate thousands of atmospheric pressures around, and insoluble dirt is destroyed to be dispersed in the cleaning liquid, and the ultrasonic cleaning has the advantages of good ultrasonic cleaning effect and simple operation. Based on the cleaning characteristics of ultrasonic waves and the tightness of the combination of the attachments such as iron oxide slag generated by high-temperature combustion of minerals and the like attached to the inner wall of the quartz combustion tube, the volume of the quartz combustion tube is selected from the following values of voltage 220-240V, power 50W, ultrasonic frequency 40000Hz and volume 2L: 2L; inner groove size: 155 x 140 x 100mm ultrasonic cleaner, placing a plastic film sleeve in a cleaning tank, placing a quartz combustion tube with an inner wall attached with attachments such as iron oxide slag generated by high-temperature combustion of minerals in the cleaning tank with the plastic film sleeve, adding 30% hydrochloric acid into the cleaning tank with the plastic film sleeve, enabling the liquid level to submerge the quartz combustion tube, starting the ultrasonic cleaner for cleaning, taking out after 15min of cleaning, repeatedly washing and drying with deionized water, and cleaning and removing the attachments such as iron oxide slag on the inner wall of the quartz combustion tube. The method has the advantages that the ultrasonic cleaner is used for removing the attachments on the inner wall of the quartz combustion tube, the cleaning effect is good, the operation is simple, the cleaning time is short, only 15min is needed, the time is only one half of that of the original method, the service life of the quartz tube is prolonged, and the method is safe, free of environmental pollution and free of damage to the health of personnel.
