High-performance activated carbon purification filter element and preparation method thereof

Abstract

The invention discloses a high-performance activated carbon purification filter element, comprising the following raw materials: 70-80 parts by weight of coconut shell activated carbon, 10-15 parts by weight of an ultra-high polymer binder, 5-20 parts by weight of vermiculite, and 10-15 parts by weight of zeolite molecular sieve . The invention also discloses a preparation method of the high-performance activated carbon purification filter element, comprising: step 1: grinding and sieving the coconut shell activated carbon, ultra-high molecular binder, vermiculite and zeolite molecular sieve in parts by weight to 250 wt. ~400 mesh, followed by mixing and stirring for 1-2 hours, preheating to 45-55 ° C, to obtain mixed powder; step 2, the mixed powder is extruded and cooled to room temperature, and then cut to obtain a filter element. In the present invention, the ultra-high polymer binder is preheated to form a better viscous flow state, and is evenly mixed with other raw materials to prevent the formation of delamination between the raw materials, the porosity is higher than 60%, the filtration efficiency is over 98.5%, and the sterilization rate reaches 99.1%.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a high-performance activated carbon purification filter element and a preparation method thereof. Background technique [0002] Activated carbon is a carbonaceous material with developed pores and adsorption, which has been widely used in the field of water purifiers. Activated carbon can effectively remove color, odor, particulate matter, bacteria, harmful chemical components and some heavy metal ions in water, thereby ensuring the safety of drinking water. In the process of water purification, the granular activated carbon has a large gap between the particles. Under a certain water pressure, due to the fast water flow, the contact time between the water and the granular activated carbon is very short, the adsorption force is not strong, and it is easy to form gap filtration. , so that part of the water cannot contact the activated carbon, and the effect of complete...

Problems solved by technology

At present, the main molding method of activated carbon filter element is sintering method, that is, after mixing activated carbon powder and binder according to a certain ratio, put it into the mold, put it into the furnace to heat after applying pressure, and then demould after cooling and molding. The process method is complex, low efficiency, high energy consumption, high production cost, low degree of industrialization, and is not convenient for large-scale continuous and rapid production
