However, it has the following disadvantages: (1) mineral materials need to be soaked and activated with acid or alkali, and then rinsed with clear water. A large amount of waste water needs to be treated during the preparation process, and the pressure on environmental protection is high; (2) mineral materials after activation and drying need to be activated Ultrafine crushing to 800-2000 mesh, high energy consumption and limited production capacity; (3) 5 to 60% activated carbon is required, which increases the cost; (4) Mineral materials are not purified and modified, which is not conducive to Its adsorption capacity is greatly improved; (5) users cannot intuitively judge when the purifier has expired during use

Embodiment 1
[0021] (1) Mineral dressing: choose zeolite, diatomite, montmorillonite and sepiolite, four kinds of pure natural mineral material concentrates with adsorption capacity, the content of which is more than 60%;
[0022] (2) Purification: the four kinds of mineral materials selected are purified respectively;
[0023] (3) Proportioning: Proportioning and mixing the four purified mineral materials, the weight ratio is 10% to 40% of zeolite, 5% to 20% of diatomite, 20% to 60% of montmorillonite, sea foam Stone 10% to 40%;
[0024] Modification: The modifying agent is sodium carbonate or sodium chloride or sodium fluoride or sodium bisulfite, and its consumption is 1% to 10% of the total weight of the mineral material after purification and proportioning. The foaming agent is ammonium bicarbonate or sodium bicarbonate, and its consumption is 1% to 10% of the total weight of the purified mineral material. According to the appropriate proportion of the weight of the mineral material...

Abstract
The invention discloses a preparation method of composite air purificant, comprising of an ore dressing step, a purifying step, a mixing step, a modification step, a granulation step, a roasting step and a finished product detecting and packing step, wherein in the ore dressing step, at least four purely natural mineral material ore concentrates with adsorbing ability are selected; in the purifying step, the selected mineral materials are purified; in the mixing step, the purified mineral material and proper caking agent are mixed properly according to weight ratio; in the modification step, modifying agent and vesicant are added, semi-drying modification is performed by adopting a kneader and drying is carried out in normal temperature; in the granulation step, a granulating machine is adopted for granulating, and active hole slash is carried out by controlling the temperature to 50 DEG C to 80 DEG C; in the roasting step, roasting activation is carried out by controlling the temperature to 200 DEG C to 300 DEG C; and in the finished product detecting and packing step, through screen separation, proper adsorption indicator allochroic silicagel particles are added, and the finished product is detected and packed to obtain composite purificant. The invention has the advantage that the performance of the product is excellent, the technology is energy-saving and environmental-friendly and can be repeatedly used; a user can intuitively judge that when regeneration is needed, the manufacture cost is low, and the like.
Description
technical field [0001] The invention relates to the preparation of a composite air purifier, in particular to a preparation method of a composite air purifier suitable for semi-dry modification and activation production. Background technique [0002] Adsorption purification method is currently one of the most widely used methods for indoor air pollution control methods. Among them: adsorbent activated carbon has good adsorption and purification ability, but the price is relatively expensive. In recent years, some natural mineral materials have attracted extensive attention as new adsorption materials, such as zeolite, diatomite, montmorillonite, rectorite, etc. Stone etc. In order to obtain a higher adsorption and purification treatment capacity, it is necessary to carry out further processing and transformation of natural mineral materials such as purification and modification, or to carry out compounding of various natural mineral materials, which has become the focus of...
