The working principle of the device is as follows:
opening the alkali liquor filling cover on the top of the device, pouring prepared alkali liquor into the neutralization tank 27 along the alkali liquor filling pipe, observing the liquid level observation window on the side surface of the device, adding alkali liquor until the liquid level observation window is properly scaled from one half to two thirds, stopping adding the alkali liquor, and covering the alkali liquor filling cover.
And opening a glass observation window of the device, opening an air draft power switch on the control panel of the electric appliance to start an air exhaust function, and simultaneously opening a power switch of the atomizer to start an alkali liquor atomization function. Placing asbestos net water on a bearing net at the bottom of the oblique-mouth digestion basket, and sequentially inserting digestion pipes filled with soil samples into the oblique-mouth digestion basket, so that the pipe orifices of the digestion pipes are inclined towards the inside of the device (forming a safe angle with an experimenter, avoiding strong acid boiling and splashing to hurt the person in the digestion process, and meanwhile, the inclination inwards is more favorable for strong acid steam generated in the digestion process to be pumped out of a digestion chamber); according to the requirements of specific experimental techniques, sequentially adding the required digestion acid liquor into the digestion tube (at the moment, strong corrosive gas volatilized by strong acid is safely pumped out of the digestion chamber); rotating the digestion basket support hanging frame to enable the bottom of the oblique-opening digestion basket to correspond well to the plane of the electric furnace; then, the height of the electric furnace is adjusted by using the hand-rotating type lifting platform, so that the plane of the electric furnace slightly has supporting force to prop against the bottom surface of the oblique-mouth digestion basket; turning on the electric furnace and adjusting the heating size to enable the heating temperature to be proper; closing the glass observation window and stewing.
Digestion in-process constantly produces acid gas and effusion test tube this moment, acid gas is under the convulsions effect of corrosion resistance air exhauster, lead the mouth and shift to the breather pipe along corrosion-resistant plastics convulsions, and then the alkali lye bottom that enters into in the neutralization pond 27 through the aeration pipe takes place abundant reaction with alkali lye, the process of the final effusion alkali lye of acid waste gas from alkali lye bottom rebound, let acid waste gas and alkali lye direct contact promptly and produce the acid-base neutralization reaction, accomplish the first acid-base neutralization treatment to waste gas. The gas continues to rise after escaping the alkali liquor, at the moment, the atomizer water inlet pipe continuously sucks the alkali liquor into the atomizer, the alkali liquor is atomized, the atomized water spray end of the atomizer continuously sprays water-mist alkali liquor, and the water-mist alkali liquor is fully contacted with the gas treated by the waste gas in the first step in the neutralization tank 27 again to form secondary acid-base neutralization treatment on the waste gas.
The pH value of the solution will be gradually reduced along with the continuous neutralization reaction between the alkali liquor and the acidic waste gas in the neutralization tank 27, the pH value of the solution is monitored by the pH detector in real time through the pH detection probe, the pH display screen on the control panel of the electric appliance is observed, and when the pH value is lower than 9, a certain amount of alkali liquor with certain concentration needs to be added into the neutralization tank 27 to maintain the pH value of the solution above 9.
The waste gas of two rounds of acid-base neutralization treatment in the front will be discharged outward after the purification of active carbon purification filter because of the effect of pressure in the case, and the concrete process is as follows: after being subjected to neutralization treatment twice in the neutralization tank 27, the acidic waste gas passes through the ventilation tubule to reach the first layer, namely the gas buffer layer, in the activated carbon purification filter, and then passes through the second and third activated carbon layers on the upper part of the activated carbon purification filter to absorb harmful waste gas possibly remaining in the gas, and finally the harmful waste gas is discharged outwards, namely the activated carbon purification filter performs third treatment on the waste gas to ensure the comprehensive purification of the waste gas.
After the sample is cooked, the hand-rotating lifting platform where the electric furnace is located is adjusted to enable the height of the hand-rotating lifting platform to be lowered until the heating plane of the electric furnace is completely separated from the bottom surface of the bevel-opening cooking basket, then the bevel-opening cooking basket supporting rack is rotated to enable the bevel-opening cooking basket to be completely rotated away from the vertical surface where the electric furnace is located, namely, the bevel-opening cooking basket is rotated to the other side of the electric furnace, then the hand-rotating lifting platform where the cooling metal block is located is adjusted to enable the hand-rotating lifting platform to be raised until the upper top surface of the cooling metal block supports and props against the bottom of the. Therefore, the purpose of quickly and uniformly reducing the high temperature of the digestion tube is achieved by utilizing the metal quick heat conduction function of the metal block and the temperature buffering of the asbestos gauze. When the temperature of the digestion tube is reduced to the room temperature, the digestion tube can be taken out in sequence, or the oblique-mouth digestion basket is taken down integrally. The digestion work is finished.
During the use process, the pH value on the pH display screen is observed, and when alkali liquor is added into the neutralization tank 27, the liquid level observation window on the side surface is observed, so that the maximum liquid level scale mark of the liquid level observation window cannot be exceeded. When the liquid level is close to the maximum liquid level scale mark and alkali liquor needs to be added, the neutralizing liquid discharging valve is opened, the solution in the neutralizing tank 27 is discharged, and the alkali liquor is added again.
