Clearing device for smoke pollutants of glass kiln and clearing method thereof

The invention relates to smoke treatment, in particular provides a clearing device for smoke pollutants of a glass kiln and a clearing method thereof. The clearing device is suitable for the glass kiln with high smoke temperature, smaller smoke amount, high clearing efficiency, stable system operation, simple structure and small floor area and is provided with an afterheat recovery boiler, a reaction tower, a bag dust collector, a circulating fluidization flume, a clean smoke recirculating flue, an absorbent bin and a feeding air flume which are sequentially connected. The clearing method comprises the following steps: smoke emitted by the glass kiln enters the afterheat recovery boiler; original smoke emitted by the afterheat recovery boiler enters a high-temperature reaction region of the reaction tower for premixing treatment with an absorbent, is accelerated by a Venturi accelerating region before entering a circulating fluidization reaction region and is cooled and purified before entering the bag dust collector; the purified smoke emitted from the reaction tower firstly enters the bag dust collector to remove particles and is emitted to a chimney by a draft fan in a purification chamber; and reaction dust emitted by the reaction tower is collected by the bag dust collector and is returned to the high-temperature reaction region.

Technique of pre-expanding treating cabo

A tobacco stalk pre-expending processing technics is provided, which is characterized in that: the technics comprises the following procedures: washing, storing, expanding in liquid and marinating with interface the tobacco stalk, expanding the stalk strips, moisture regaining and feeding, storing, pressing sticks and drying for shaping. The technics method of the invention changes the expanding of cut rolled stem into expanding the tobacco stick by using marinating with high temperature and low pressure and then expanding with high temperature and reduced preddure, thus sufficiently eliminating the bad flatus in the tobacco stick as the flatus of the wood or the corrupt straws; the tobacco stick after expanded has increased cells and remarkably enhanced ratio surface, thus the material liquid can filter into the tobacco sticks sufficiently to becoming a natural filling material and adaptation carrier for adjusting the cigarette fragrance and style; the cigarette stick after expanded is large in volume, which, after pressed, is easy being cut into silkiness (similar as the physical behavior of tobacco shred); after dried and shaped normally, the cut rolled stem can crisp naturally, thus increasing the filling capacity. The cut rolled stem processed by the technics method of the invention is basically similar with tobacco shred in color and shape and the alloying evenness of the tobacco shred is increased; besides, the tobacco shred has no bad aftertaste when smoking, but has strong filling capacity and enhanced internal quality.

Method of preparing electrode material for carbon-based supercapacitor by taking bamboo powder as raw material

The invention provides a method of preparing electrode material for a carbon-based supercapacitor by taking bamboo powder as raw material. The method includes the following steps: under the protection of nitrogen, evenly mixing a carbonized product with alkali and water after bamboo powder as raw material undergoes two-stage carbonization, heating the above mixture to enable the water content of the mixture to be 10%-30% of that of the original mixture, conducting two-stage activation, cleaning and drying the mixture to obtain alkali activated bamboo powdered carbon, adding the alkali activated bamboo powdered carbon into a phosphor and nitrogen doped solution, conducting ultrasonic uniform mixing, then conducting a hydro-thermal reaction, and finally obtaining a finished product after post-treatment is conducted on a reaction solution. Cheap, environment-friendly and renewable bamboo that is easily available is taken as raw material to prepare carbon material for a supercapacitor, so the method has the noticeable cost advantage. Through two-stage carbonization and two-stage activation, impurities in bamboo material can be fully removed, and porous carbon material with high carbon content can be formed. Moreover, a phosphor, nitrogen and hetero atom codope process is introduced to enable bamboo carbon to have extra fake capacitance, so the capacitive performance of the supercapacitor can be greatly improved.

Glutinous rice wine and preparation method thereof

The invention discloses glutinous rice wine and a preparation method thereof. The glutinous rice wine is prepared according to the following steps: 1) soaking glutinous rice into water, steaming or cooking and cooling to 25 to 28 DEG C to obtain cooked glutinous rice; 2) adding a fermenting agent in an amount which is 0.1 to 1 percent of the weight of the glutinous rice into the cooked glutinous rice, saccharifying, adding water in an amount which is 2 to 5 times that of the cooked glutinous rice, and fermenting to obtain fermented wine, wherein the saccharification temperature and the fermentation temperature are 25 to 28 DEG C, the saccharification time is 24 to 48 hours and the fermentation time is 48 to 72 hours; 3) centrifugally separating the fermented wine and taking the clear liquid to obtain the wine sample; 4) adding white spirit in an amount which is 15 to 25 percent of the weight of the glutinous rice and white sugar or crystal sugar in an amount which is 5 to 15 percent of the weight of the glutinous rice into the wine sample, sterilizing and ageing to obtain aged wine; and 5) filtering the aged wine by using a microporous filter and filling to obtain the product, wherein the fermenting agent consists of 10 to 20 weight percent of yeast and 80 to 90 weight percent of Q303 rhizopus. According to the preparation process, mixed fermenting agent and various impurity-removing methods are adopted, so the saccharification time can be shortened. The prepared glutinous rice wine is transparent and plump, and has mellow mouthfeel, moderate sweetness and special flavor of glutinous rice.

Vacuum rotary dryer

PCT No. PCT / JP97 / 04543 Sec. 371 Date Aug. 10, 1998 Sec. 102(e) Date Aug. 10, 1998 PCT Filed Dec. 10, 1997 PCT Pub. No. WO98 / 26244 PCT Pub. Date Jun. 18, 1998A vacuum rotary dryer capable of charging solids into a rotary drum and discharging the solids from the rotary drum without any manual operation contacting solids with the hands is provided. A rotary drum (23) is mounted thereon with a gas flow pipe (46) and a solids feed and discharge pipe (56). The solids feed and discharge pipe (56) is connected to a feed source of the solids and a pressure reducing unit (53) reduces a pressure in the rotary drum through the gas flow pipe (46), to thereby feed solids to be dried to the rotary drum (23). After drying of solids in the drum, the solids feed and discharge pipe (56) is connected to a solids suction and transport structure and the gas flow pipe (46) is rendered open to an atmospheric pressure. A swing section (56b) of the solids feed and discharge pipe (56) is pivotally moved, to thereby be intruded into solids while keeping the rotary drum (23) inclined, resulting in solids being removed through a distal end of the swing section by suction. Finally, the distal end of the swing section (56b) is rendered opposite to a lowermost portion of the rotary drum to remove substantially all solids in the rotary drum therefrom.
