Embodiment 1

[0051] combine Figure 1-2 , an inert gas protection system for industrial adsorbers, including a multi-chamber split combined adsorber 21 and an inert gas inlet, and also includes a temperature controller 27 and a temperature detection element, and the multi-chamber split combined adsorber 21 is provided with There is an inert gas inlet, and the temperature detection element is located in the multi-chamber split combined adsorber 21. The temperature detection element is electrically connected to the temperature controller 27, and the temperature controller 27 controls the inert gas in and out of the inert gas inlet.

[0052] The temperature detection element detects the temperature signal in the multi-chamber split combined adsorber 21 and transmits it to the temperature controller 27. Once the temperature of the multi-chamber split combined adsorber 21 is too high, the temperature controller 27 controls the inert gas from the inert gas The air inlet enters into the multi-cha...

Embodiment 2

[0056] An inert gas protection system for industrial adsorbers, including a multi-chamber split combined adsorber 21 and an inert gas inlet, and also includes a temperature controller 27 and a temperature detection element. The multi-chamber split combined adsorber 21 is equipped with In the inert gas inlet, the temperature detection element is located in the multi-chamber split combined adsorber 21. The temperature detection element is electrically connected to the temperature controller 27, and the temperature controller 27 controls the inert gas in and out of the inert gas inlet.

[0057] The multi-chamber split combined adsorber 21 is also provided with an adsorption air inlet, an adsorption air outlet, a desorption air inlet and a desorption air outlet, which are connected with the adsorption air inlet, the adsorption air outlet, and the desorption air inlet. The pipeline connected to the desorption outlet and the desorption exhaust port is equipped with an adsorption inta...

Embodiment 3

[0059] This embodiment is similar to Embodiment 1-2, except that the number of adsorbers in the multi-chamber split combined adsorber 21 is greater than or equal to one; each adsorber is equipped with a temperature detection element; each temperature The detection element detects the temperature signal in each adsorber in the multi-chamber split combined adsorber 21 and transmits it to the temperature controller 27. Once the temperature in any one of the multi-chamber split combined adsorber 21 is too high, The temperature controller 27 controls the inert gas to enter the adsorber of the multi-chamber split combined adsorber 21 from the inert gas inlet, and the inert gas is continuously filled into the multi-chamber split combined adsorber 21 to cool down and replace the Oxygen, to achieve fire extinguishing, cooling function.

[0060] Once the temperature of an adsorber in the multi-chamber split combined adsorber 21 is too high, from figure 2 It can be seen from the figure ...

Abstract

The invention discloses an inert gas protection system for an industrial adsorber and an operation control method thereof, belonging to the field of environmental protection safety. The inert gas protection system comprises a multi-chamber splitting combined adsorber, a nitrogen gas inlet, a temperature controller and a temperature detection element, wherein the multi-chamber splitting combined adsorber is provided with the nitrogen gas inlet; the temperature detection element is located in the multi-chamber splitting combined adsorber; the temperature detection element is in electric signal connection with the temperature controller; the temperature controller is used for controlling inert gas to enter and exit from an inert gas inlet; and pipelines communicated with an adsorption gas inlet, an adsorption exhausting hole, a desorption gas inlet and a desorption gas outlet of the multi-chamber splitting combined adsorber are correspondingly provided with an adsorption gas inlet control valve, an adsorption exhausting control valve, a desorption gas inlet control valve and a desorption exhausting control valve. According to the inert gas protection system, line connection can be changed on an existing high-temprature combustible adsorber and temperature detection and control devices are arranged and upgrading and improvement are directly carried out, so that the cost is saved.

Description

technical field [0001] The invention relates to the fields of exhaust gas physical adsorption purification, thermal desorption and safety protection of processing equipment, and in particular to an inert gas protection system for industrial adsorbers and an operation control method thereof. Background technique [0002] The increasingly serious smog in recent years has made the environment more and more pressured, and people are paying more and more attention to environmental protection. Low-concentration, high-volume volatile organic waste gas is a difficult-to-treat waste gas that widely exists in the packaging, printing, rubber, spraying and electronics industries. Due to the complex components of pollutants and low concentration, they usually have no recycling value, and direct treatment technology is very difficult. . [0003] Adsorption technology is often used in engineering for preliminary concentration to increase the concentration of pollutants in the treated gas,...
