Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0039] The following describes the automatic control method and device of the adsorption regeneration system according to the embodiments of the present invention with reference to the accompanying drawings.

[0040] Figure 1 It is a flow chart of the automatic control method of the adsorption regeneration system according to the embodiment of the present invention.

[0041] like Figure 1 As shown, the method includes:

[0042] S1, initially controlling the first adsorbent regeneration temperature of the adsorption regeneration system;

[0043] In one embodiment of the present invention, during initial startup, the adsorbent regeneration temperature of the adsorption regeneration system can be controlled to be the first adsorbent regeneration temperature by controlling the heat exchanger steam regulating valve and the heat cycle fan.

[0044] In one embodiment of the present invention, the first adsorbent regeneration temperature is obtained through artificial experience or experiments, wherein the first adsorbent regeneration temperature may be 350° C. In one embodiment of the present invention, the first adsorbent regeneration temperature may also be any temperature in the first interval, and the first interval may be [347° C., 353° C.].

[0045] S2, obtaining a second adsorbent regeneration temperature of the adsorption regeneration system;

[0046] In one embodiment of the present invention, after the adsorption regeneration system is started, the second adsorbent regeneration temperature during the operation of the adsorption regeneration system can be obtained.

[0047] In one embodiment of the present invention, the second adsorbent regeneration temperature can be obtained in real time.

[0048] S3, automatically controlling the adsorption regeneration system based on the first adsorbent regeneration temperature and the second adsorbent regeneration temperature.

[0049] In one embodiment of the present invention, after the first adsorbent regeneration temperature and the second adsorbent regeneration temperature are obtained through the above steps, the adsorption regeneration system can be automatically controlled based on the first adsorbent regeneration temperature and the second adsorbent regeneration temperature.

[0050] In one embodiment of the present invention, the method for automatically controlling the adsorption regeneration system based on the first adsorbent regeneration temperature and the second adsorbent regeneration temperature may include the following steps:

[0051] S31, determining whether the second adsorbent regeneration temperature is less than the first adsorbent regeneration temperature;

[0052] S32, if the second adsorbent regeneration temperature is lower than the first adsorbent regeneration temperature, determining whether the second adsorbent regeneration temperature is lower than the third adsorbent regeneration temperature;

[0053] S33, if the second adsorbent regeneration temperature is less than or equal to the third adsorbent regeneration temperature, performing a first control on the adsorption regeneration system until the second adsorbent regeneration temperature is greater than the third adsorbent regeneration temperature;

[0054] S34, if the second adsorbent regeneration temperature is greater than the third adsorbent regeneration temperature, determining whether the second adsorbent regeneration temperature is less than the fourth adsorbent regeneration temperature;

[0055] S35: If the second adsorbent regeneration temperature is lower than the fourth adsorbent regeneration temperature, the adsorption regeneration system is subjected to a second control.

[0056] In one embodiment of the present invention, after obtaining the second adsorbent regeneration temperature, it can be determined whether the second adsorbent regeneration temperature is less than the first adsorbent regeneration temperature. If the second adsorbent regeneration temperature is less than the first adsorbent regeneration temperature, it means that the adsorbent regeneration temperature is decreasing. Based on this, it can be determined whether the second adsorbent regeneration temperature is less than the third adsorbent regeneration temperature to determine whether the adsorption regeneration system needs to be controlled. In one embodiment of the present invention, the third adsorbent regeneration temperature can be the lowest temperature that the adsorbent regeneration temperature can be.

[0057] And, in one embodiment of the present invention, the third adsorbent regeneration temperature may be set according to experiments. In one embodiment of the present invention, the third adsorbent regeneration temperature may be 335°C.

[0058] Further, in one embodiment of the present invention, if the second adsorbent regeneration temperature is less than or equal to the third adsorbent regeneration temperature, it means that the material needs to be reduced to match the corresponding temperature and the temperature is increased. Based on this, the adsorption regeneration system is automatically controlled in the first way to match the corresponding adsorbent regeneration temperature and material. In one embodiment of the present invention, the first control can be a material circulation instruction to reduce the material in a circulation mode with a first threshold and a preset time interval. And, in one embodiment of the present invention, the first threshold and the preset time can be set according to manual experience or experiments. For example, the first threshold can be 0.5t / h (tons / hour) and the preset time is 1min (minutes). Then the corresponding first control is a material circulation instruction to reduce the material in a circulation mode with a 0.5t / h interval and a 1min interval until the second adsorbent regeneration temperature is greater than the third adsorbent regeneration temperature.

[0059] In one embodiment of the present invention, after the first control is performed on the adsorption regeneration system, the method may further include the following steps:

[0060] Step 1, determining whether the material circulation is less than a second threshold;

[0061] Step 2: If the material circulation is less than the second threshold, the adsorption regeneration system is subjected to a third control.

[0062] In one embodiment of the present invention, the second threshold value may be obtained based on experiments, for example, the second threshold value is 15 t / h. Also, in one embodiment of the present invention, the second threshold value may be the lower limit of material circulation. If the material circulation is less than the second threshold value, the adsorption regeneration system may be controlled thirdly to automatically control the adsorption regeneration system. In one embodiment of the present invention, the third control may include: the material circulation instruction stops reducing the material.

[0063] And, in one embodiment of the present invention, if the second adsorbent regeneration temperature is greater than the third adsorbent regeneration temperature, it is also necessary to determine whether the second adsorbent regeneration temperature is less than the fourth adsorbent regeneration temperature to determine whether the adsorption regeneration system needs to be controlled. In one embodiment of the present invention, the fourth adsorbent regeneration temperature can be set based on manual experience or experiments, for example, the fourth adsorbent regeneration temperature is 340°C.

[0064] Specifically, in one embodiment of the present invention, if the second adsorbent regeneration temperature is less than the fourth adsorbent regeneration temperature, the adsorption regeneration system needs to be second controlled to match the corresponding adsorbent regeneration temperature and material. In one embodiment of the present invention, the second control may include locking the material circulation instruction to increase to stop the increase of the material.

[0065] The automatic control method of the adsorption regeneration system of the embodiment of the present invention initially controls the first adsorbent regeneration temperature of the adsorption regeneration system; obtains the second adsorbent regeneration temperature of the adsorption regeneration system; and automatically controls the adsorption regeneration system based on the first adsorbent regeneration temperature and the second adsorbent regeneration temperature. Therefore, the present invention can automatically control the adsorption regeneration system based on the adsorbent regeneration temperature without manual operation, and realizes the automatic matching between the material circulation and the adsorbent regeneration temperature, so that the material circulation can be accurately controlled, so that the adsorbent regeneration temperature is controlled and stabilized, and the circulation efficiency is improved.
