Description

Integrated batch water content tester

Technical Field

The utility model relates to the technical field of water content detection, in particular to an integrated batch water content tester.

Background

The water content test is an indispensable link in many production practices, and the water content detection of the fly ash chelating solidified body is an indispensable link in the fly ash treatment. The incineration fly ash is produced in municipal household garbage incineration, inorganic substances form solid particles in the garbage incineration process, wherein the larger solid particles are deposited on the bottom of the incinerator and the fire grate and are called bottom ash, fine particles float in flue gas and enter a flue gas purification system together with the flue gas, the particles form 50% of the incineration fly ash, the rest of the incineration fly ash is derived from limestone or activated carbon added in the flue gas purification process and are commonly trapped in a dust remover, and meanwhile, a part of fine particles are deposited at the bottom of a flue and a chimney, and the trapped and deposited fine particles are called the incineration fly ash. The main treatment mode of the incineration fly ash is chelation solidification landfill. The fly ash chelate solidified body which is not detected to be qualified is forbidden to enter the landfill. And the duration of the fly ash chelating solidifying body from sampling to finally finishing leaching toxicity test is up to more than 40 hours, and a large amount of fly ash samples can only be stored in workshops, so that the occupied area is increased, and the project operation cost is increased. It is therefore particularly important to complete the fly ash treatment detection operation quickly. According to the standard method, the leaching turnover oscillation time of the fly ash solidified body is 18+/-2 hours and cannot be shortened, so that the method can only start from other links, and the water content test is particularly time-consuming, so that the method and the instrument for rapidly detecting the water content of the fly ash chelate solidified body are sought to reduce the optimal break-through of the leaching toxicity detection time of the whole fly ash chelate solidified body. The current method for detecting the moisture content of the fly ash chelating solidified body is mainly an oven drying method, wherein the fly ash is contained in a crucible, the crucible is used for containing the fly ash, the crucible is placed into an oven for heating to 105 ℃ after being weighed, the moisture is continuously dried for more than eight hours, the crucible is taken out for cooling, and then the crucible is weighed, and the moisture content of the fly ash is calculated. At present, the experiment time for measuring the water content by using an oven drying method is too long, the efficiency of fly ash test is reduced, and the fly ash landfill requirement cannot be met. In fact, the low efficiency of the moisture content test affects not only the fly ash treatment efficiency, but also other production practices involving the moisture content test.
