With the enhancement of human environmental awareness, petroleum resources are not renewable. Human beings pay more and more attention to the use of renewable resources. A large number of plastic products are used in household appliances and electronic products that are closely related to people's daily life. The main components are: ABS, PS PP PE. Home appliances and electronic products manufactured by it are eliminated after a period of use and replacement. As a result, a large number of waste plastic products are accumulated and abandoned, which has a certain impact on the environment, and the waste materials have not been well reused.

 

 

The process route is as follows: the mixed plastic enters the first brine separator, and salt is added to adjust the specific gravity of the brine, so that the calcium-added PS\ABS\metal is separated, and the floating ABS\PS\PP\silica gel enters the first stage after dehydration. In the secondary brine separator, the specific gravity of the brine can be adjusted to separate environmental protection materials. The floating ABS\PS\PP\silicon glazes are environmentally friendly materials, which enter into separate cleaning and enter the rinsing separator. After a variety of materials, one heavy and water PS, ABS, submerged PP, silica gel, one light and water PP, rinsed again and entered the dehydrator for dehydration. PS, ABS and submerged PP are separated by electrostatic separation. Two-stage removal of silica gel and two-stage static electricity can separate PS, ABS, submerged PP, and silica gel respectively. The separation accuracy is about 97%. The separated plastics are respectively Concentrated granulation. The second-stage brine separation sediment accounts for 80%, which is transported by the dehydrator PS\ABS\PP\silica gel into the rinse separator. After the separation of two materials by the water specific gravity method, one is heavy and water PS, ABS, and submerged water. PP, silica gel, a light and water PP. For PS, ABS and submerged PP, electrostatic separation is used to achieve separation. Two-stage removal of silica gel and two-stage static electricity can separate PS, ABS, submerged PP, and silica gel, respectively, with a separation accuracy of about 97%. The separated plastics are respectively Centralized processing. Recycled ABS, PS, PP, PE, and other materials can be modified, processed and granulated to obtain plastic modified materials with higher added value. The output is 1-5T/H, the power consumption is 200-650KW, and the floor area is 1000-7000 square meters
