POWDER DEGREASING AGENT, PREPARATION METHOD THEREFOR AND DRYING DEVICE THEREOF

WIPO Patent Application WO/2022/016688

A1

A powder degreasing agent, a preparation method therefor and a drying device therefor. Sodium hydroxide is adopted, the saponification effect is high, and the powder degreasing agent has higher cleaning capacity. 4A zeolite is added to avoid attachment of oil stains, so that the cleaning capacity is further improved. Particularly, an EO/PO block polymer is added, so that a good deoiling effect is achieved, and a foam inhibiting and defoaming effect is achieved. Alcohol ether glucoside is used for compatibilizing the EO/PO block polymer. A main tank body (1) and sub-tank bodies (2) are integrally arranged, and the sodium hydroxide reacts when meeting water heat, so that heat energy utilization is improved, and energy is saved; a stirring device continuously stirs a solution in the main tank body (1) by means of a first stirring device (4) and a third stirring device (6), a second stirring device is used for stirring the solution in the sub-tank bodies (2), and the solutions are more easily mixed via mutual stirring. The third stirring mechanism (6) is formed by superposing stirring units with spiral structures, and is used for cutting and mixing the solution to realize stirring of the solution; and the whole solution is in an active state, and dissolution of the solution is further promoted.
