The invention provides a cleanable spiral heat exchanger. The cleanable spiral heat exchanger comprises a main body, a first end cover and a second end cover; the main body is wound by a first U-shaped groove plate and a second U-shaped groove plate, which are laminated; the first U-shaped groove plate and the second U-shaped groove plate respectively form a first spiral channel and a second spiral channel; the bottom of the first U-shaped groove plate is positioned at a first end of the main body; and the bottom of the second U-shaped groove plate is positioned at a second end of the main body. In the cleanable spiral heat exchanger, when the first spiral channel is blocked, the second end cover is only disassembled; then, a first cavity is inflated through an air supply mechanism, so that the inside of the first spiral channel can be flushed through a first air valve without disassembling the first end cover and emptying the second spiral channel, and the flushing difficulty is greatly reduced; and similarly, when the second spiral channel is blocked, the first end cover is only disassembled, and the second spiral channel is washed by air through the air supply mechanism and a second connecting head.

Provided is a scanning type bedpan flushing mechanism. A pair of flushing main bodies are both of a semi-annular tubular hydraulic water tank structure and both look like a nozzle walking groove whichis as long as a half inner ring, and each half ring also serves as a semi-arc hollow piston running guide pipe of the semi-annular tubular hydraulic water tank. After water is supplied to the semi-annular tubular hydraulic water tanks, the pressure of water counteracts the elasticity of springs, semi-annular tubular pistons are pushed to move along the half guiding rings when water is sprayed bya nozzle at the frontmost end of each semi-annular tubular piston to the wall of a bedpan, and therefore a scanning type semi-arc flushing mode is achieved. After supply of the water is stopped, underthe drawing effect of the tension springs in the semi-annular tubular pistons, the semi-annular tubular pistons retract when water remaining in the hollow pistons is extruded by the nozzles at the frontmost ends of the semi-annular tubular pistons to the wall of the bedpan. The two flushing main bodies which look like walking grooves are symmetrically stacked and installed to form a whole circular scanning type bedpan flushing mechanism body. The scanning type bedpan flushing mechanism moves like a bicycle lock during locking. According to the mechanism, the flushing amount for meeting flushing and cleaning requirements is far more lower than that of a pedestal pan.

The invention discloses a digital active wet process transfer printing method of a cellulose fabric. The digital active wet process transfer printing method of the cellulose fabric is performed by the five steps: manufacturing a special transfer printing medium; jet-printing a pattern; pre-processing a fabric; performing transfer printing; and performing post-finishing of the fabric. According to wet process transfer printing, by spraying a pre-processing liquid, the fabric is dyed and fixed in color in a clinical water content stat when fibers are subjected to maximum swelling without taking urea as a moisture absorbent, and the fabric is not padded and pasted, so that the washing difficulty is reduced, and sewage discharge is reduced. The method disclosed by the invention not only has the advantages of clear and smooth digital inkjet printing pattern and rich layers of picture, but also has the characteristics of efficient production of conventional transfer printing and environmental protection and energy conservation, and further has the characteristics that the active print is bright in color, excellent in hand feel, good in color fastness and healthy and comfortable.

The invention relates to a pretreatment method for high-efficiency enzyme hydrolysis of wood waste fiber. According to the pretreatment method, the wood waste fiber is pretreated by using mixed solution of metal chloride solution and a surfactant, the pretreated raw material is subjected to cellulase hydrolytic saccharification; and reducing sugar obtained by hydrolysis can be used for producing a biofuel by fermentation. Glucose in enzymatic hydrolysate is determined by using a glucose oxidase-peroxidase method, and total glucan in the raw material is determined by using acid process hydrolysis, so that the hydrolysis rate of the glucose in the raw material is calculated. After the wood waste fiber is pretreated under the pretreatment conditions that the mass ratio of metal chloride to the surfactant is 2.4-4.8 (w / w), the temperature is 160-200 DEG C, the heat preservation time is 0-240 minutes and the liquid-solid ratio is 8:1, hydrolysis is performed by using a complex enzyme of cellulase and beta-glucosaccharase to produce the glucose, and the final hydrolysis rate reaches 60-91 percent.

The invention discloses a low-shrinkage treatment method and device and an after-treatment method. The low-shrinkage treatment method comprises the following steps that soaking and complete squeezingare conducted at least one time; wet boiling spraying loose-type piling is conducted at least one time; low-tension spraying vibration washing treatment is conducted at least three times; complete squeezing and drying are conducted. According to the low-shrinkage treatment method for a highly-elastic fabric, the highly-elastic fabric can be produced continuously, the production efficiency is improved, using of manpower, water and equipment is reduced, and production cost of production process links and the like is reduced. After treatment by the low-shrinkage treatment method, the effects of high-elasticity and low-shrinkage rate of the highly-elastic fabric can be achieved, and therefore the difficultly in highly-elastic type garment production and garment washing is reduced.

The invention belongs to the technical field of loose fiber dyeing and relates to cold-pad batch dyeing process for loose fibers. The cold-pad batch dyeing process for loose fibers comprises the steps of soaking and squeezing, rotating type cold-patch treatment, pressing and water squeezing and post-treatment. The loose fibers are soaked and squeezed in a twice soaking and once squeezing mode, the rotating type cold-patch treatment is then conducted, the loose fibers are pressed and water is squeezed out after the rotating type cold-patch treatment is conducted, and after the water and dye in a loose fiber cake or loose fibers are squeezed out, the loose fiber cake or loose fibers are sent for post-treatments of drying and the like. The cold-pad batch dyeing process for loose fibers is applied to cold-pad batch dyeing of the loose fibers and has the advantages of being uniform in dyeing, small in water consumption and the like. In addition, procedures are simple.
