The most common acids is evaporated in Asia boiling mode, obtain high purity acid steam, the method cleaning vessel with such acid vapor.In existing common sour steaming washer design, process at Row control, spent acid, heat and in terms of temperature control, Liquid level, be usually present some problem.

1, Row control:

(1) existing solution mostly just can only provide the acid of the first step to steam cleaning step, remain a need for user and manually each vessel are used one by one the acid solution of pure water rinsing remained on surface, then remain a need for user and manually vessel are placed on air dry oven drying or natural air drying, waste time and energy very much.

(2) if using the mode that air dry oven is dried; because air dry oven inherently metal material is made; and the air sucked is not done strict filtration and purification; and the daily thing that also can be dried other, this mode will face air dry oven or the unholiness secondary pollution problem brought of air.

(3) if using the mode of natural air drying, will be the most oversize.

2, spent acid processes:

(1) after acid vapor produced by existing solution cleans vessel surface, being condensed into liquid (referred to herein as " spent acid "), spent acid typically without any process, is passed straight back in " totally acid ", continues to participate in evaporation.

(2) acid is steamed to clean and why to be used sub-boiling mode to evaporate, and purpose is contemplated to make evaporation process become slow, it is to avoid drop Residual contamination thing pollutes vessel.And these spent acid contain substantial amounts of pollutant, being passed straight back to clean acid, meeting severe contamination is the sourest, and along with the continuation of cleaning process, pollutant levels can be more and more higher, even if sub-boiling state, also cannot avoid pollutant recontamination vessel.So that cleaning performance is had a greatly reduced quality.

3, heating and temperature control:

(1) existing solution usually avoids temperature sensor to be corroded easily by high-temperature strong acid, its temperature sensor is installed in container exterior, avoid contacting with strong acid, but what such mounting means was measured is the temperature of container outer wall or heater, the true temperature of acid solution cannot be reflected, generally 10-30 DEG C to be differed with the temperature of container outer wall or heater of solution temperature, the measurement error of temperature is the biggest.

(2) existing solution temperature dependent controller carrys out temperature control, and heater itself does not possess self-temperature controlling function.Once temperature controller lost efficacy, and continuation is heated by heater, causes instrument to burn the great risk of even laboratory fire.

4, Liquid level:

(1) for the Liquid level of clean acid solution, existing solution is because being the circulation pattern of evaporation-condensation-backflow-evaporation, therefore liquid level does not have the biggest change in whole process, and inside acid gas is steaming, it is difficult to observe level condition from outside, the most any liquid level monitoring measure.

(2) for the Liquid level of spent acid acid solution, existing technical scheme is typically directly to make spent acid acid solution be back to clean acid, does not makes a distinction clean acid solution and spent acid acid solution, and therefore the Liquid level to spent acid acid solution does not has any surveillance and control measure.
