Problems solved by technology

[0005] Due to the large particle size of granular activated carbon, the form of multiple activated carbons after being placed in water is relatively easy to control and relatively easy to recycle, so it is widely used; while the particle size of powdered activated carbon is small, it is difficult to form a large amount of powdered activated carbon when using powdered activated carbon to treat water. control, it is easy to lose with the flow of water, so that the adsorption and purification effect of powdered activated carbon cannot be fully exerted, and the subsequent coagulation reaction is required to separate powdered activated carbon from water, which greatly restricts the application of powdered activated carbon in water treatment

Embodiment 1

[0030] A method for fixing powdered activated carbon in a fluid, comprising the steps of,

[0031] A magnetic component is installed in the center of the housing with a flow channel, and emits a magnetic field to the flow channel in the housing;

[0032] Magnetic particles are added to the magnetic field in the flow channel, and the magnetic particles accumulate under the action of the magnetic field to form a layer of magnetic particles that can filter the fluid and prevent the powdered activated carbon from losing with the fluid.

[0033] In this method, a magnetic skeleton capable of stabilizing magnetic particles is arranged in the magnetic field.

[0034] In the method, the magnetic particles are fixed by the magnetic field to form a magnetic particle layer, and the powdered activated carbon is fixed through the magnetic particle layer, which can prevent the powdered activated carbon from being lost with the fluid flow, so that the powdered activated carbon can be used fo...

Abstract

The invention discloses a method for fixing powdered activated carbon in fluid and a purification device. According to the principle, a magnetic field is provided through a magnetic component, magnetic particles are fixed through the magnetic field, a magnetic particle layer is formed, the powdered activated carbon is fixed through the magnetic particle layer, and the powdered activated carbon does not run off along with flowing of the fluid. When the fluid is purified, the purification of the fluid is completed by contacting the powdered activated carbon with the fluid; the purification device provided by the invention can realize large-scale use of the powdered activated carbon, so that the available range of the powdered activated carbon is wider, the practical operability is higher, and the problem that the powdered activated carbon is easy to run off along with the flowing of a medium is solved.

Description

technical field [0001] The invention relates to the purification treatment of fluid, in particular to a method for fixing powdered activated carbon in fluid and a purification device. Background technique [0002] Activated carbon can be divided into powder activated carbon or granular activated carbon according to its appearance and shape. Generally, activated carbon with more than 90% passing through the 80-mesh standard sieve or with a particle size of less than 0.175mm is generally called powdered activated carbon or powdered carbon, and activated carbon with a particle size greater than 0.175mm is called granular activated carbon; and With the advancement of separation technology and the emergence of certain application requirements, the particle size of powdered carbon tends to be more and more refined, and in some cases it has reached the micron or even nanometer level. [0003] Granular activated carbon is a kind of micro-quality carbon material made of carbonaceous ...
