Embodiment 1

[0030] A kind of method adopting inorganic binding material to make activated carbon rod, it comprises the following steps:

[0031] 1) Stir and mix 1 kg of water glass, 0.2 kg of additives and 10 kg of cement, and control the water-cement ratio to 0.8 to obtain the first material, add 60 kg of activated carbon powder and 5 kg of zeolite powder to the first material and stir evenly to obtain the second material;

[0032] 2) Sending the second material into an extruder for extrusion molding, and curing the formed carbon rods to obtain the activated carbon rods.

[0033] The carbon rod prepared in this example passed the standard addition test, and the removal rate of residual chlorine was over 99.9%, and the removal rates of heavy metals lead, cadmium, mercury, chromium and arsenic were all over 99.9%.

Embodiment 2

[0035] 1) Stir and mix 3 kilograms of water glass, 1 kilogram of additives and 20 kilograms of cement, and control the water-cement ratio to 1.5 to obtain the first material. Add 80 kilograms of activated carbon powder and 10 kilograms of zeolite powder to the first material and stir evenly to obtain the second material;

[0036] 2) The second material is fed into an extruder for extrusion molding, and the formed carbon rod is steamed and cured for 4 hours to obtain the activated carbon rod.

[0037] The carbon rod prepared in this example passed the standard addition test, and the removal rate of residual chlorine was over 99.9%, and the removal rates of heavy metals lead, cadmium, mercury, chromium and arsenic were all over 99.9%.

Embodiment 3

[0039] 1) Stir and mix 2 kilograms of water glass, 0.6 kilograms of additives and 15 kilograms of cement, and control the water-cement ratio to 1.1 to obtain the first material, add 70 kilograms of activated carbon powder and 8 kilograms of zeolite powder to the first material and stir evenly to obtain the second material;

[0040] 2) The second material is sent into an extruder for extrusion molding, and the activated carbon rod is brushed with a layer of the third material before the formed carbon rod is naturally cured, and steamed and cured for 5 hours to obtain the obtained Described activated carbon stick; Wherein, 1 kilogram of water glass, 0.2 kilogram of additives and 20 kilograms of cement are stirred and mixed, and the water-cement ratio is controlled to be 1, obtains the 3rd material.

[0041] The carbon rod prepared in this example passed the standard addition test, and the removal rate of residual chlorine was over 99.9%, and the removal rates of heavy metals lea...

Abstract

The invention discloses a method for making an activated carbon rod by using an inorganic bonding material, which comprises the following steps: 1) stirring and mixing 1-3 parts by weight of water glass, 0.2-1 parts by weight of an auxiliary agent and 10-20 parts by weight of cement, The water-cement ratio is controlled to be 0.8-1.5 to obtain the first material, add 60-80 parts by weight of activated carbon powder and 5-10 parts by weight of zeolite powder to the first material and stir evenly to obtain the second material; 2) mix the second The material is fed into an extruder for extrusion molding, and the shaped carbon rod is maintained to obtain the activated carbon rod. The activated carbon rod prepared by the invention has the characteristics of high porosity, high removal efficiency of residual chlorine and heavy metal, excellent antibacterial performance and the like.

Description

technical field [0001] The invention relates to the field of activated carbon rods. More specifically, the present invention relates to a method for making activated carbon rods using inorganic binder materials. Background technique [0002] Activated carbon rod filter elements have excellent adsorption properties, and it is more and more common to use activated carbon rods as filter elements in water purifiers and air purification. However, the carbon rods in the current activated carbon filter elements are mostly extruded with powdered activated carbon and organic binders. Due to the high price of organic binders, the price of activated carbon rods remains high, which brings difficulties to the popularization of water purifiers. Contents of the invention [0003] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages as will be described hereinafter. [0004] Another object of the present i...
