Problems solved by technology

The first-generation dehumidification wheel uses lithium chloride solution as an adsorbent, which has high moisture absorption capacity and low regeneration temperature, but it is easy to escape and corrode peripheral equipment.
The second generation dehumidification wheel is activated silica gel wheel (SSCR), but the silica gel will lose its activity when the temperature rises to 200C
In the honeycomb runner for adsorption prepared by this method, the adsorbent is deposited on the surface of the honeycomb, the capacity of the loaded adsorbent is low, and the adsorption capacity is small; the bonding strength between the adsorbent and the honeycomb matrix is ​​weak, and it is easy to fall off and fail during use.

Abstract

The present invention relates to a core material employing a rotating wheel adsorption system for dehumidification or gas treatment, and provides a manufacturing method for a novel high-performance core material used for rotating wheel adsorption, wherein an adsorbing material is filled in the processing process of a ceramic honeycomb paperboard, and after expanding the surface of the honeycomb material by using mechanical methods, the adsorbing material is deposited on the surface by using an impregnation method, with a large loading amount and high bonding strength. The manufacturing method for the high-performance core material is characterized by comprising the steps of: (1) adding organic fiber into a wood pulp suspension under stirring, and then, after the fiber is uniformly dispersed, adding a retention aid, molecular sieves and ceramic fiber to give a slurry; (2) by using a wet method, manufacturing the slurry into form and drying until a moisture content thereof is 5 to 25% to obtain wet paper; (3) preparing a portion of the wet paper into ceramic fiber corrugated paper by thermoforming; and preparing the other portion of the wet paper into ceramic fiber flat paper by puncture or ganization with a needle machine or raising organization with a raising machine; (4) thermoforming after bonding the ceramic fiber corrugated paper with the ceramic fiber flat paper, and obtaining ceramic fiber double-faced corrugated paper by heating and sintering.

Description

technical field [0001] The invention relates to a method for manufacturing an adsorption core, in particular to a core material for dehumidification or waste gas treatment by means of a rotary adsorption system. Background technique [0002] Rotary adsorption technology is widely used in the fields of dehumidification and waste gas treatment. Sweden first proposed the concept of making the adsorption material into a runner with a honeycomb structure for the separation process, but at that time it failed to realize industrialization due to the limitations of materials and processing technology. Japan took the lead in bonding corrugated and flat ceramic fiber paper with inorganic adhesives and rolling it into a runner with a honeycomb structure, and coating hydrophobic molecular sieves on the surface of the honeycomb channel to make an adsorption rotor. The wheel is used in the purification process of VOC in industrial waste gas. [0003] The core component of the wheel adso...
