As shown in fig. 1 to 5, the present invention provides a method for measuring residual water content in regeneration of an adsorbent, comprising the steps of:
firstly, conveying ambient air into a constant-temperature water bath box 2 for heat exchange, removing condensed water by a gas-liquid separator 3, performing adsorption drying by an adsorption tower 4 and then leading the ambient air to the outdoor for discharge by a discharge port 41 in sequence by an air compressor 1;
step two, when the moisture content of the gas exhausted from the adsorption tower 4 is increased to a set dew point temperature, acquiring the adsorbed weight of the adsorption tower 4, and calculating to obtain the ideal dynamic adsorption capacity of the adsorbent;
step three, conveying ambient air into a heater 7 in sequence by a blower 6 to heat, regenerating the adsorption tower 4, and introducing the regenerated ambient air to the outdoor through a discharge port 41 for discharging;
and step four, when the regeneration of the adsorption tower 4 reaches the set regeneration time, acquiring the regenerated weight of the adsorption tower 4, and calculating to obtain the regeneration residual water quantity of the adsorbent.
And step five, comparing the ideal dynamic adsorption quantity of the adsorbent with the regeneration residual water quantity of the adsorbent to obtain the effective adsorption capacity of the adsorbent in the adsorption cycle.
The ideal dynamic adsorption amount refers to a dynamic adsorption amount measurement value of an adsorbent in a dry state (the water content is lower than 0.5%), and in order to ensure the accuracy of the ideal dynamic adsorption amount measurement of a sample, the water content of the adsorbent sample needs to be measured before weighing, and the water content of the sample is ensured to be lower than 0.5%.
In particular, a temperature-adjusting heat tracing band is laid outside the adsorption tower, so that the temperature of the adsorption bed can be adjusted to the required condition before the test is started.
In addition, the scheme can utilize the air blower to convey ambient air to simulate the regeneration process of the blast heat regeneration adsorption type dryer to measure the residual water content of the adsorbent, and can also be connected with low dew point clean air output by the regeneration gas generation device to simulate the regeneration process of the heatless or micro-heating adsorption type dryer so as to quantify the effective adsorption capacity of the adsorbent in the adsorption cycle.
It is worth mentioning that, as shown in fig. 4 and 5, under the same regeneration conditions, the regeneration residual water amounts of different types of adsorbents are completely different, and the regeneration residual water amounts of the same type of adsorbents are different due to factors such as raw materials, processing technology, and process control.
Wherein the amount of regeneration residual water in the adsorbent bed will reduce its actual adsorption capacity. In the working cycle of the adsorption dryer, the actual dynamic adsorption capacity of the adsorbent bed layer is the difference value between the ideal dynamic adsorption capacity and the regeneration residual water quantity. The more the regeneration residual water amount is, the more adverse to the actual dynamic adsorption amount is; the smaller the amount of the regeneration residual water, the more favorable the actual dynamic adsorption amount. If the regeneration of an adsorption tower of the adsorption dryer is completed, the adsorption capacity of the adsorption bed in the next working period is reduced directly due to the fact that the residual water in the regeneration of the adsorbent in the tower is too high, and the quality of compressed air at the outlet of the equipment is affected.
Preferably, in the second step, the ideal dynamic adsorption amount of the adsorbent is obtained by dividing the difference between the post-adsorption weight of the adsorption column 4 and the pre-adsorption weight of the adsorption column 4 by the pre-adsorption weight of the adsorbent.
In the fourth step, the regeneration residual water amount of the adsorbent is obtained by dividing the difference between the regenerated weight of the adsorption tower 4 and the pre-adsorption weight of the adsorption tower 4 by the pre-adsorption weight of the adsorbent.
The adsorption tower 4 is placed on the weighing sensor 42, and the weighing sensor 42 is used for measuring the adsorbed weight of the adsorption tower 4 and the regenerated weight of the adsorption tower 4.
As shown in fig. 1, a first flow meter is arranged between the air compressor 1 and the constant temperature water bath tank 2, a dew point test device 5 is connected to one side of an outlet of the adsorption tower 4, a second flow meter is arranged between the outlet of the adsorption tower 4 and the discharge port 41, a third flow meter is arranged at the rear end of the dew point test device 5, the first flow meter and the second flow meter are used for detecting the flow of compressed air or regeneration gas, the third flow meter is used for detecting the flow of dew point analysis gas, and the first flow meter, the second flow meter and the third flow meter are respectively marked as P1, P2 and P3 in fig. 1.

In addition, the device for measuring the residual water after the regeneration of the adsorbent, provided by the scheme, further comprises a plurality of valves, which are respectively marked as B1-B10 in figure 1, and are used for controlling the switching of pipelines between the adsorption path and the regeneration path.
Wherein, can detect pressure, temperature through above-mentioned each flowmeter, temperature detection spare, manometer, and then obtain adsorbent adsorption capacity data under different pressure, the temperature operating mode.

(ambient air) → air compressor (supercharging) → constant temperature water bath tank (temperature regulation) → gas-liquid separator (removing condensed water) → adsorption tower (drying) → exhaust port (leading to outdoor discharge);
wherein the exhaust port is led to the outside and is provided with a muffler for reducing exhaust noise.

(ambient air) → blower (pressurization) → heater (warming) → adsorption tower (regeneration) → exhaust port (leading to outdoor discharge);
wherein, the blower adopts a Roots blower, and the heater adopts a low-power density electric heater.
In the process of measuring the regeneration residual water quantity of the adsorbent, firstly closing the valves B1, B3 and B4, and opening the valve B5 to ensure that the regeneration residual water quantity is measured to enter a standby working state and a compressed air generation system is fully isolated; and then, after the ambient air is pressurized by a blower 6, the ambient air is heated by a heater 7 and enters the adsorption tower 4 to carry out heating dehydration treatment on the adsorbent in the tower. After the set regeneration time is finished, the blower 6 and the heater 7 are turned off. The weight sensor 42 is used for weighing the adsorption tower 4 to obtain the regenerated weight of the adsorption tower, and the regeneration residual water amount of the sample adsorbent under the regeneration condition can be calculated, wherein the calculation formula is as follows:
