Two-way operation steam-injection method

The invention relates to a two-way operation steam-injection method which comprises the following steps: S01, building a pot bottom of which the section is shaped like a gliding wild goose on the ground, wherein the pot bottom like the gliding wild goose consists of a steam-injection part of a bilateral symmetry structure, and the steam-injection part comprises a road surface and a slope on one side of the road surface; S02, setting a ceiling above the slope, wherein a steam-injection cavity is formed between the ceiling and the wall surfaces on the left and right sides of the slope; S03, embedding a steam-injection pipeline for injecting steam into a digesting cavity on the surface of the slope; S04, forming a water outlet at the bottom of the slope; S05, shoveling the broken bamboo chips or saw dust on the ground into the digesting cavity by virtue of a forklift driven by a driver; S06, sealing the inlets on two sides of the digesting cavity; and S07, opening the steam injection pipeline, and digesting for a preset time. The discharging operation is realized by utilizing the forklift. The slope of the ground serves as the pot bottom, the two-way operation can be performed, and the timber steam-injection feeding and discharging efficiency is improved.
