preparation example Construction

[0048] A method for preparing a new environmentally friendly plastic alloy material made from garbage and sludge, comprising the following steps:

[0049] The rubbish is sent to the crushing mechanism 500 for crushing treatment to obtain crushed rubbish. When the garbage is crushed, the combustibles (such as plastics, fabrics, bamboo, wood, leather, rubber, paper, etc.) become smaller than 30 mm, and the inorganic substances (such as glass, ceramics, masonry, shells, metals, etc.) It becomes less than 0.2 mm, and perishables (such as vegetables, meat, bones, shells, waste oil, etc.) become muddy.

[0050] The pulverized garbage, or the pulverized garbage mixed with the mixed sludge is sent to the extruding mechanism 600 for extrusion dehydration treatment to obtain the dehydration intermediate.

[0051] The dehydrated intermediate enters the first screw heater 100 for drying and melting to obtain a melt. The heating temperature of the first screw heater 100 is 100°C-230°C. ...

Embodiment 1

[0059] This embodiment provides a method for preparing a new environmentally friendly plastic alloy material produced from garbage and sludge.

[0060] A method for preparing new environmentally friendly plastic alloy materials made from garbage and sludge, comprising the following steps:

Abstract

The invention discloses equipment and a preparation method for preparing an environment-friendly plastic alloy new material from garbage and sludge in a full-dose mode. The equipment for preparing the environment-friendly plastic alloy new material from the garbage and sludge in a full-dose mode comprises a first screw heating machine, a grinding and mixing machine, a second screw heating machine and a forming mechanism, wherein the first screw heating machine, the grinding and mixing machine, the second screw heating machine and the forming mechanism are connected in sequence. According to the equipment for preparing the environment-friendly plastic alloy new material from the garbage and the sludge in a full-dose mode, full-dose resource recycling of the garbage and the sludge can be achieved, zero incineration and zero landfill are achieved, the construction number of garbage incineration power plants and sludge treatment plants can be greatly decreased, therefore, land occupation and carbon emission are greatly reduced, in addition, waste recycling can be achieved, garbage and sludge treatment cost is reduced, and contribution is made to development of circular economy.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a device and a preparation method for completely producing environmentally friendly plastic alloy new materials from garbage and sludge. Background technique [0002] Garbage still contains a large amount of low-value, mixed, and polluted materials after source classification, recycling and reduction, such as plastics, textiles, rubber, leather, paper, bamboo and wood, and other high-molecular materials. Currently, incineration power generation is mainly used for disposal. However, incineration power generation only utilizes the thermal energy of these materials, which is not strictly speaking a recycling, and does not conform to the concept of circular economy, and also produces slag and fly ash that need to be disposed of separately. Sludge is the residue of sewage treatment, which is composed of water, organic powder and inorganic powder. At present, it is mainly dispos...
