Production of ethyne by coal and natural gas plasma pyrolyzation and its apparatus are disclosed. It is produced by spraying plasma, buggy steam current and natural gas protective gas in plasma reactor, reacting and generating mixed ethyne gas, cooling, separating, storing ethyne, passing gas into plasma generator and reutilizing, sprayed natural gas forming gas protective layer on plasma reactor wall to prevent carbon fragment from coking, and pyrolytic reacting to obtain mixed ethyne gas. It achieves high converting efficient and reacting efficient.

A W-shaped flame boiler disposing aperture type over-fire air spouts on a stove arch relates to a W-shaped flame boiler. The invention aims at solving the problems of existing W-shaped flame boilers that the burnout degree of coal powder is low, and the efficiency of the boiler is reduced when simultaneously increasing over-fire air and reducing the discharge of NOx. A plurality of the aperture type over-fire air spouts are divided into two groups, the two groups of the aperture type over-fire air spouts are symmetrically arranged along the central line of a boiler body, a group of aperture type over-fire air spouts are correspondingly arranged on each stove arch near the neck aperture of a hearth, one group of the aperture type over-fire air spouts are arranged in parallel along the length direction and are all communicated with a lower hearth of the lower boiler body, the sections of the aperture type over-fire air spouts are rectangles with the ratio of length to width is (5-7):1, and the central line of each aperture type over-fire air spout and the horizontal line form an included angle of 20-35 degrees. The distance between adjacent aperture type over-fire air spouts is 100 mm. The setting of the aperture type over-fire air spouts prolongs the reacting time between uncombusted coal powder granules and the over-fire air, and enables the combustion to be more compete.

The invention relates to an estimation method of weathering measurement relationship between salt-based ions and silicon in soil mixed minerals. The estimation method comprises the following steps: adding weathered soil samples without sundries into a centrifugal bottle; adding an EDTA-ammonium acetate solution into the soil samples, and performing uniform stirring, sealing, and vibration in sequence; performing centrifugal filtration, collecting supernatant, and determining the content of salt-based ions in the supernatant; repeating the steps until the content of the salt-based ions in the collected supernatant is not changed any longer; washing redundant EDTA-ammonium acetate in soil with ammonium-free ethanol; adding an acid rain leaching solution into the soil samples of which salt bases are eluted, performing uniform stirring, vibration and centrifugation, performing filtration, collecting supernatant, and determining pH, the content of silicon and the content of the salt-based ions; every 6 days, repeating drip washing, calculating the acid rain leaching quantity of each salt-based ion, and the weathering measurement relationship between the salt-based ions and the silicon. According to the estimation method disclosed by the invention, a batch (Batch) method is adopted, so that the eluting capacity is powerful, and the eluting effects are good. According to the soil exchangeability salt-based elution method, the experiment effects and the precision are remarkably improved, and the soil exchangeability salt-based elution method has wide application prospects.

The invention relates to a low-pressure discharge plasma water treating apparatus, mainly comprising a discharge power supply, a high voltage electrode, a reactor, an atomization sprinkler, a water inlet pipe, a water outlet pipe, a water flow monitor, an air exhaust pipe, an air valve, a vacuum pump, a sewage pool and a clean water reservoir. According to the invention, without a water pump, a low pressure environment in the reactor can be maintained via only one vacuum pump under the condition that water flows through the reactor; electro-discharge is carried out in the low pressure environment, and large-volume, high-activity and non-thermal equilibrium plasma is generated; the treating apparatus can effectively remove pollution sources like heavy metal ions, organic matters and microbes in water, has high treatment efficiency, is generally applicable to sewages having different pollution degrees and produced by different industries and provides activated water for special industries. The invention further relates to a plasma water treating method which realizes low pressure discharge under the condition that a water cycle between the interior of the reaction chamber and the outside is maintained without usage of a forced exhaust type water pump. With the method, system energy consumption is greatly reduced.
