Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the drawings.

[0021] reference figure 1 As shown, an embodiment of the present invention is a method for on-line regeneration of activated carbon fibers, which includes and preferably performs the following steps:

[0022] Step A. Immerse the activated carbon fiber in a closed container filled with water, and connect the activated carbon fiber to the DC electrode;

[0023] Step B: Continuously inject ozone into the water inside the closed container within the first fixed time;

[0024] Step C. After the first fixed period of time, drain the water inside the closed container, re-inject water that has not passed the activated carbon fiber into the container again, disconnect the electrode connected to the activated carbon fiber, and heat the water in the closed container To boiling, and keep it in a boiling state for the second fixed time;

[0025] Step D: After the second fixed time is over, drain the wa...

Abstract

The invention discloses an online activated carbon fiber regeneration method, and belongs to an application mode of activated carbon fibers. The online activated carbon fiber regeneration method comprises the steps of A. immersing activated carbon fibers in a closed container with water, and connecting the activated carbon fibers into a direct current electrode; B. constantly injecting ozone into the water in the closed container within first fixed time; C. after the first fixed time, draining the water in the closed container, then injecting water at least submerging the activated carbon fibers into the closed container again, disconnecting the electrode from the activated carbon fibers, and heating the water in the closed container to be boiled, wherein the water in the closed container is kept in the boiled state in second fixed time. As ozone replaces chlorine dioxide, the influence on water purification of the activated carbon fibers caused by chloride ions is effectively alleviated. The water in the container is heated in an electric heating manner, and electric heating equipment is simpler in structure compared with automatic steam equipment, so that the use cost is low, and the online activated carbon fiber regeneration method is easy to popularize and use.

Description

Technical field [0001] The present invention relates to an application mode of activated carbon fibers. More specifically, the present invention mainly relates to a method for online regeneration of activated carbon fibers. Background technique [0002] At present, the method of online regeneration of activated carbon fiber used in activated carbon fiber filter devices on the market is generally to connect it to an AC electrode, inject chlorine dioxide into the water, and combine steam to heat the water. The main disadvantage of this method in practical application is: because the electric field formed by alternating current is unstable, it is not conducive to the adsorption of ions in the water on the electrode, resulting in poor electrochemical effect, and the water purification effect is worse than direct current; at the same time, the chlorine ion itself It is a hazardous substance and one of the pollution factors that need to be controlled in water. Therefore, the addition o...
