Problems solved by technology

A lot of waste is produced during the production of these products, and the plastic in the waste will cause a lot of white pollution to the environment
At present, the method of heating and incinerating waste materials not only wastes raw materials, but also pollutes the atmospheric environment on which human beings depend for survival because of the large amount of harmful gases produced during incineration.

Embodiment Construction

[0018] The specific design and operating parameters of the present invention are related to the type and daily processing capacity of waste materials.

[0019] 1. If the daily processing capacity of waste is about 1 ton, and the ratio of paper and plastic is 6:4, the power of the heating furnace is about 300,000 kcal / hour, and the volume of the agitator and dehydrator is 0.5m 3 Around, pulp oven volume is 9m 3 Around, the volume of the plastic oven is 4m 3 About, the volume of the reactor is 2m 3 About, the still volume is 5m 3 About, the power of the vacuum pump is about 3kW. The specific steps are:

[0020] 1) Heat the system to 80°C-150°C.

[0021] 2) Put the paper and plastic waste into the mixer 1, put the reagent into the mixer 1, stir and heat, and then put the materials into the separator 2.

[0022] 3) Adjust the rotating speed of the separator 2 to separate the solid and liquid, and send them to the stirring cleaner 3 and the distillation kettle respectively.

Abstract

A process for reclaiming the leftover of disposable sanitary paper-plastic articles includes proportionally mixing said leftover with tetrachloro ethylene, stirring while heating to dissolve the plastic component in liquid, solid-liquid separation, dewatering the paper pulp in solid and drying it to obtain the raw pulp, distilling the liquid and drying to obtain raw plastics.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and energy saving. In particular, it relates to a method for regenerating paper and plastic from waste materials of disposable paper and plastic sanitary products. technical background [0002] With the continuous development of my country's industrial and technological level and the continuous improvement of people's living standards, the number of disposable paper-plastic sanitary products is increasing, such as sanitary pads for women's products, "diapers" diapers for daily use, etc. A large amount of waste is generated in the production process of these products, and the plastic in the waste will cause a large amount of white pollution to the environment. At present, the method of heating and incinerating waste materials not only wastes raw materials, but also pollutes the atmospheric environment on which human beings depend for survival due to the large amount of harmful gas...
