The invention relates to the field of separation and purification, and discloses a scrubber, a washing device and a method for purifying polyolefin catalysts. The scrubber includes a first chamber and a second chamber separated by a first partition and a second partition and the third chamber, wherein the first partition is provided with a plurality of small holes that allow the materials in the first chamber to pass through and can prevent most of the materials in the second chamber from entering the first chamber, the second partition The bottom of the plate is provided with an opening, the first chamber and the second chamber are respectively provided with feed ports, and a separation mechanism is provided in the third chamber, and the separation mechanism can make the washed material and the washed agent separation, the third chamber is also provided with at least two outlets for discharging the washed materials and detergent out of the washer respectively. The method of the invention has the advantages of short washing time, high impurity extraction rate and small solvent consumption, and can realize dynamic cycle continuous washing and purification process.

The invention is concerned with the embedding-type filtering-cloth filtering pad that is with double-angle feed and double-angle outputting, includes: the membrane and liner, the feed hole locates at the filtering cloth filtering pad double-angle, the feed sub-hole locates on the top of the filtering cloth and connects with the feed hole; the outputting hole locates at the filtering cloth filtering pad double-angle and faces to the feed hole respectively, the outputting sub-hole locates at the reverse of the filtering cloth and joins with the outputting hole. The advantages are: reduces the pipeline and the valve, and the production cost, shorts the technics period; the structure as the beer filtering pad that is not only decrease the channels namely reduce the pipelines and valves, reduce the cost and technics period.

A digital printing dyeing treatment agent, preparation method and application method, which is prepared by using cationic auxiliary agent, cationic etherification agent, humectant, organic solvent and water to prepare coupling cationic graft modifier and spray it on the pretreated fabric On the back, after drying and digital printing, soak in the coupling reaction agent prepared by reactant, organic acid and water, the reaction solution of color developer prepared by color developer and water, and the color fixation reaction prepared by color fixer and water The solution was colored for 30 seconds, and finally washed with water. The invention has the advantages of fast digital dyeing process at room temperature without high temperature, and can use direct dyes, acid dyes and reactive dyes to dye various fibers.

The invention discloses multifunctional washing oxygen granules and a preparation method thereof. The invention solves the problems of poor washing effect and harm to the human body in the existing washing product. The oxygen granules comprise sulfonic acid, sodium carbonate, sodium sulfate, sodium peroxycarbonate and sodium carboxymethyl cellulose. The preparation method of the oxygen granules comprises the following steps: (1) preparing the following raw materials in percentage by mass: 5-10% of sulfonic acid, 25-35% of sodium carbonate, 10-25% of sodium sulfate, 20-60% of sodium peroxycarbonate and 1-5% of sodium carboxymethyl cellulose; (2) sequentially mixing the sulfonic acid, sodium carbonate, sodium sulfate, sodium peroxycarbonate and sodium carboxymethyl cellulose under anhydrous and low constant temperature conditions to obtain a mixture; (3) granulating the mixture at low temperature; and (4) drying the obtained granules at constant temperature. The technique is simple; and the oxygen granules prepared by the method have favorable washing effect and high capacities of stain removal, sterilization, bleaching and odor removal.

The invention belongs to the technical field of chlorinated polyethylene preparation, and particularly relates to a production process of chlorinated polyethylene. The process comprises the followingsteps: adding hydrochloric acid into the polyethylene, carrying out a reaction on the hydrochloric acid and the polyethylene, and then dissolving the polyethylene; after the polyethylene is dissolved,adding an oxidizing agent and an initiator for replacement; after the replacement is completed, introducing chlorine to carry out a chlorination reaction; after the chlorination is carried out through the introduction of the chlorine for 30 minutes, carrying out filtration treatment to obtain a high-concentration chlorinated polyethylene solution; feeding the chlorinated polyethylene solution into a filter for deacidification; feeding the chlorinated polyethylene solution subjected to filtration and deacidification into a centrifugal machine for dewatering, and then carrying out drying to obtain a chlorinated polyethylene product; and carrying out washing, drying and sieving on the chlorinated polyethylene product obtained in the step 6 through a chlorinated polyethylene comprehensive treatment device. The process is mainly used for producing chlorinated polyethylene on a large scale, and the three working procedures comprising washing, drying and sieving of chlorinated polyethylene are integrated into one device, so that the production efficiency is improved.
