Abstract
The invention discloses a treatment method for water jetting non-woven processing water which consists of, subjecting the recirculated water to water injection board, fabric net, vacuum pumping, gas water separation, highly effective air-floating, static state sand filtration, accurate belt type filtering, accurate bag type filtering, accurate core type filtering, high pressure pump pressurization and safety filtration net. During the highly effective air-floating procedure, the charge of electrolyte coagulating agent, demulsifying agent, and coagulant aid can remove various colloids and fabric oil solution in the circulating water, the static state sand filtration can filter the small particles in the water, while the mechanical filtration can eliminate the solid particles, big colloids and suspended substance.
Description
Technical field
The present invention relates to the treatment process of water in a kind of textile industry, relate in particular to a kind of treatment process of spunlace non-woven process water.
Background technology
Spunlace non-woven technology is a kind of method of non-woven, and it is to utilize the superfine current of high pressure continuously of liquid drugs injection head ejection that the fiber on the fibre web is carried out random entanglement to all directions, stings non-manufacturing cloth through obtaining water behind dehydration, the stoving process then.So its requirement to quality is very high, water technology in the at present domestic and international spunlace non-woven technology is to have utilized the more sophisticated water technology of other industrial sectors basically, the full mechanical screening device of the many employings of this technology, its treatment effect is just to the solid particulate matter, the big colloid or the specific filtration resistance of suspended substance are more useful, and to the emulsification finish, tiny or software suspended substance such as Mierocrystalline cellulose accumulations and microorganism viscosity mud just can not filter out fully, its result just causes quality product, the obstruction of the water needle plate that production efficiency plays a crucial role, when serious even can't produce, caused the mode of a large amount of use clear water to be kept producing and ensured the quality of products, moreover increase that filtering materials at different levels consume or cleaning are frequent, increase production cost again, reduced economic benefit.
Summary of the invention
The purpose of this invention is to provide a kind of spunlace non-woven process water treatment process.
Because processing not only has man-made fiber, synthon in spunlace non-woven production, also have natural and biological fiber etc., so contain the material in the necessary place to go of four big classes in the spunlace non-woven technology in the recirculated water, it is respectively: one is fibre finishing; Two are the short little fibril of considering to be worth doing and breaking away from of each fibrid from fiber; Three is microorganism and foundry loam; Four is the Mierocrystalline cellulose accumulations.When carrying out circulating water treatment, adopt earlier pneumatically supported mode with micro-bubble as carrier, adhere to the impurity particle in the water, make its density less than water, carried under one's arms by bubble then and shift to the water surface and water sepn removal, then tackle superfine small particle in the water body, and then the mechanical filter that carries out precision carries out purifying treatment to reach to recirculated water, the purpose of cleaning circulation water with the mode of static sand filtration.
Spunlace non-woven process water treatment process technology provided by the present invention is simple, cost is low, it has introduced air flotation technology and static husky filter technology in traditional spunlace non-woven process water treatment scheme, water treatment method with chemistry, physics combines effectively, improve the effect of water treatment greatly, reduced production cost.
Description of drawings
Fig. 1 is the process flow sheet of spunlace non-woven process water treatment process of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
In spunlace non-woven technology, when recirculated water carries out getting back to water needle plate by the high-pressure pump pressurization by the safety filtering net after efficient air-floating, static sand filtration, the filtration of accurate belt, accurate bag type filtering, the filtration of accurate core formula after vacuum take-off, gas-water separation via water needle plate, fibre web.Described efficient air-floating is to carry out in efficient air-floating apparatus, before this in order to make various small elimination of colloid stability and the cohesion in the recirculated water, to in water, add the ionogen coagulating agent, its content is between 20-30ppM, can make coacervation of colloid become bigger particle, simultaneously, because the fibre finishing that dissolves in the water body is an emulsified state, also to carry out breakdown of emulsion toward adding emulsion splitter in the water body, and make it be condensed into bigger elaioleucite, emulsion splitter content can be by by the absorption of the microbubble that dissolved air release produced in the efficient air-floating apparatus and rise to the water surface with microbubble and separate when colloid and fibre finishing are condensed into larger particles between 5-10ppM; In addition, in order to strengthen flocculating result, help microbubble absorption and separating treatment, also can add coagulant aids in water, its content is between 5-10ppM.Said coagulating agent can be an aluminium iron polychloride; Said coagulant aids can be a hydro-polyacrylamide.Described static sand filtration is to carry out in static sand filtering device, the filter sand floor height is 1m in the static sand filtering device, divide three layers of filling, the particle diameter of sand is between 0.5-1.5mm, utilize the gravity of water to filter during work, the top water inlet, the bottom water outlet is to reach the purpose of utilizing layer of sand to tackle fine particles poly-agglomerating in the water body.And then carry out meticulous belt filtration, bag type filtering, core formula and filter to remove a small amount of fine particle of solid, colloid or suspended substance, reach recirculated water is handled, the purpose of cleaning circulation water.
