The invention provides a manufacturing method of a high-hardness plastic screen and a high-hardness plastic housing of a mobile phone, and a mobile phone screen and a mobile phone housing manufactured by the manufacturing method. The manufacturing method comprises the following steps: performing secondary compressing and forming to obtain a base plastic material; cleaning and drying the base plastic material through electrostatic eliminated drying gas for the first time; soaking in an adhesive for the first time; cleaning and drying the base plastic material covered with the adhesive through the electrostatic eliminated drying gas for the second time; soaking in enhanced liquid containing silicide, nanometer aluminum oxide and corundum for the second time; roasting; hardening; trimming. The product manufactured by the method is free of rainbow-like marks, high in light transmission rate, and high in density; the hardness of the product is up to 9H, and is equal to or beyond that of a traditional glass screen; in addition, the product is hard to break, so that the product can completely replace glass to be used as the screen of the mobile phone; compared with a glass material, the plastic is low in price, so that the cost of the mobile phone screen manufactured through the plastic is low, and as a result, the use cost of a user can be decreased.

The invention relates to a regeneration method for removing an oxygen compound containing adsorbent in low-carbon olefins, and mainly solves the problems that the operation is complicated; the regeneration efficiency is low; the adsorbent can be easily coked and generate carbon deposition, so that the adsorption performance of the adsorbent is reduced or even inactivated, and the like. The regeneration method has the technical scheme that stepped programmed temperature rising is performed at lower pressure and a temperature higher than the adsorption temperature; the adsorbent requiring regeneration contacts positive or reverse flowing high-temperature drying gas with heat. The problems are well solved; the regeneration method can be used for removing the oxygen compound containing adsorbent in industrial low-carbon olefins.

A temperature-humidity exchanger comprising: a moisture permeable membrane which transmits moisture therethrough; a dry gas separator in which low-temperature dry gas is caused to flow; and a wet gas separator in which high-temperature wet gas is caused to flow, in which the moisture permeable membrane, the dry gas separator, the moisture permeable membrane, and the wet gas separator are repeatedly stacked in the stated order, wherein in the dry gas separator and the wet gas separator: a plurality of channel grooves which are divided by half in the stacking direction, are open to a direction in which the channel grooves come into contact with the moisture permeable membrane, and are arrayed parallel to one another are provided; an aggregate communication groove which is made to communicate with both end portions of the plurality of channel grooves, for aggregating gas caused to flow through the channel grooves to at least one is provided; and a supply manifold and an exhaust manifold which are made to communicate with the aggregate communication groove and penetrate the separators in the stacking direction are provided; and a flow of the dry gas caused to flow in the channel grooves of the dry gas separators and a flow of the wet gas caused to flow in the channel grooves of the wet gas separators are counterflows.

The invention relates to a countercurrent shaft-drawer type drying machine with a movable drawer for drying agglomerations with low mechanical strength, comprising a vertical, preferably, rectangular shaft (1), wherein the shaft comprises a top part, at least one layer, preferably, two layers of material inlet regions (2), a multi-layer drying region (3) preferably comprising two to six layers and a bottom part, and at least one layer, preferably, two layers of material outlet regions (4); an outlet short pipe or an outlet current collector (5) of dry gas is arranged between the material outlet region (4) at the bottom and the drying region (3); an outlet short pipe or an outlet current collector (6) of wet gas is arranged between the drying region (3) and the material inlet region (2) at the top; baffles (8) of the material inlet region (2) and baffles (10) of the material outlet region (3) are made of numerous rectangular non-perforated metal sheet plates; baffles (9) of the drying region (3) are made of numerous rectangular perforated metal sheet plates; and the baffles (8, 9, 10) made of the rectangular metal sheet plates are connected to parallel pins (11) which are rotationally arranged in the wall of the shaft (1) and are transverse to a shaft line of the shaft (1) along long edges of the baffles.

The invention relates to a method for producing a gasoline blending component from dry gas. The method comprises that dry gas contacts benzene on a catalyst, wherein the catalyst is a binder-free ZSM-5 molecular sieve with a silicon aluminum mole ratio SiO2/Al2O3 of 30-900 and a crystal grain diameter of 10-800 nm, and is treated with water vapor. According to the present invention, the method can be used to produce the high-octane value clean gasoline blending component through the reaction of the refinery dry gas and the benzene.

The invention relates to a drying room system with mixed application of a radiator and furnace gas, in particular to an intelligent hot water source incense stick and tobacco drying room system. The system comprises a boiler, a furnace gas emission chimney, an electrostatic dust collector, a boiler induced draft fan, a multi-tube dust collector, a furnace gas cleaning device and a plurality of drying room devices.
