The invention discloses a method for willow artwork dyeing through a natural indigo pigment. The method comprises the following aspects that (1) indigo extraction is conducted, specifically, a plant raw material is subjected to crushing, fermentation, water soluble extraction and low-temperature drying, and the indigo pigment is prepared; (2) acid-alkali steeping is conducted, specifically, a hydrochlric solution with the concentration being 0.3-0.4% and a sodium hydroxide solution with the concentration being 0.25-0.3% are used to steep a willow artwork correspondingly; (3) cooking for impurity removal is conducted, specifically, impurities in the willow artwork is removed through cooking; (4) steaming for dyeing is conducted, specifically, the indigo pigment with the mass being 11-13% that of distillation boiler water is added, and steam dyeing is conducted; (5) low-temperature drying is conducted, specifically, the dyed willow artwork is dried; (6) infrared color fixing is conducted, specifically, the willow artwork is wrapped through mixed slurry and placed under infrared lamplight with the illumination intensity being 470-520 lux for color fixing; (7) ultraviolet inspection is conducted, specifically, the willow artwork subjected to color fixing is placed under an ultraviolet lamp, and the color fixing condition is inspected; and (8) tung oil layer coating is conducted, specifically, the willow artwork qualified after inspection is coated with tung oil, and after drying, the willow artwork with the natural indigo pigment is prepared.

A cyclone-type multi-layer air intake hood installed in a biomass combustion furnace, which includes a face mask and cyclone blades, is characterized in that the multi-layer air intake hood is composed of two or more than two face masks, and a fire hole is arranged in the center. The cyclone blades are evenly installed on the inner wall of the mask. The whirlwind blades are linear or arc-shaped, uniformly distributed obliquely with the fire holes, and the surface of the whirlwind blades is installed at a certain angle with the inner wall of the mask. The mask overlaps with the mask to form a multi-layer air inlet. The invention has simple structure, scientific air intake mode, remarkable energy gathering effect, can promote pyrolysis and combustion of tar and steam, improves thermal efficiency, reduces consumption of biomass energy, and reduces carbon emission. The invention is suitable for biomass burning stoves.

The invention discloses a special cartridge for a laneway outline and a production method of the special cartridge. The special cartridge comprises an antistatic cartridge case and emulsified explosive, wherein the antistatic cartridge case is a thin-wall cylinder; one end of the thin-wall cylinder is sealed and the other end of the thin-wall cylinder is opened; the thin-wall cylinder is filled with the emulsified explosive through one open end; a cylinder wall of the thin-wall cylinder is provided with two groups of energy releasing gaps along the longitudinal direction; the two groups of energy releasing gaps are symmetrically distributed along the radial direction of the thin-wall cylinder; each group of energy releasing gaps comprise a plurality of gaps which are not communicated with one another and are collinear, and the gaps have wide inside and narrow outside. The gaps, which are not communicated with one another, are used as the energy releasing gaps, so that explosion energy can be collected better and the better laneway outline is obtained.
