Abstract: An air conditioner indoor unit includes a housing, a panel, a fan assembly, a first air guide assembly, and a first driving assembly. The panel includes a first air outlet. The first air guide assembly is located on a side of the panel away from the housing, and a second air outlet is constituted between an edge of the first air guide assembly and an edge of the first air outlet. The first driving assembly is configured to drive the first air guide assembly to move relative to the panel, so as to change a size of the second air outlet to adjust a flow direction of air flowing out from the second air outlet. The first air guide assembly includes a flow direction changing structure, and the flow direction changing structure is configured to move in a direction different from a moving direction of the first air guide assembly.

Abstract: Disclosed are a pulverized coal preprocessing method and a pulverized coal gasifying method. The pulverized coal preprocessing method comprises the following steps: (1) performing pore broadening on pulverized coal to obtain preprocessed pulverized coal; (2) loading alkali metal ions into the preprocessed pulverized coal under an ion exchange condition to obtain alkali metal loaded pulverized coal. The method further comprises loading a chrome complex into the alkali metal loaded pulverized coal obtained in described step (2). In gasification, the pulverized coal loaded with alkali metal potassium and chrome catalysts obtained by the method has the advantages of high sulphur removal rate, high carbon conversion rate, short gasifying reaction time and high methane production.

Abstract: Provided is an organic-inorganic polymeric water-retaining fertilizer, which is a co-polymer made by fusion and co-polymerization of an organic water-retaining monomer and an inorganic nutrient under action of a catalyst, a biological enzyme and a modifying agent. The co-polymer is of a three-dimensional mesh-like hydrophilic group structure. In a method for preparing the organic-inorganic polymeric water-retaining fertilizer, after obtaining a neutralized pre-polymer from the organic monomer with the catalyst, an initiator and a cross-linking agent are added; the inorganic nutrient and a metasilicate are added simultaneously, a solution is formed by stirring sufficiently; the biological enzyme is added for catalysis; a co-polymer is obtained after fusion and co-polymerization; and granulation and drying are carried out. Preferably, the catalyst is an inorganic alkaline solution.
