Embodiment 1

[0019] Implementation steps of a method for preparing solid waste hollow ceramsite:

[0020] 1) Preparation of hollow ceramsite core body: fully mix 8 parts of sawdust and 2 parts of sludge by weight, and roll it into a ball in a ball-forming disc as a core body, and the diameter of the core body is 3-10 mm;

[0021] The wood chips are about 200 meshes, which are waste wood chips produced in the wood processing process, and a considerable amount of wood chips contain a large amount of phenolic resin glue; the sludge is produced by pressure filtration in the dewatering machine room at the source of sewage treatment in Qingyuan Company, and it contains 70-90 % water and a lot of organic matter;

[0022] 2) Pretreatment of shell raw materials: Mix ceramsite shell raw materials according to the weight ratio of 10 parts of fly ash and 1.5 parts of sludge, and mix them well; ;

[0023] 3) Preparation of ceramsite raw material balls: put the prepared core raw material balls into th...

Embodiment 2

[0028] Implementation steps of a method for preparing solid waste hollow ceramsite:

[0029] 1) Preparation of hollow ceramsite core: Fully mix 6 parts of wood chips and 3 parts of sludge by weight, roll it into a ball in a ball-forming disc as a core, and the diameter of the core is 3-10mm:

[0030] The wood chips are about 200 meshes, which are produced during the process of making the base material of the wood-based company into products, and the wood chips contain a large amount of phenolic resin glue; ~90% water and a lot of organic matter;

[0031] 2) Pretreatment of shell raw materials: Mix ceramsite shell raw materials according to the weight ratio of 8 parts of fly ash and 1 part of sludge, and mix them well; .

[0032] 3) Preparation of ceramsite raw meal balls: put the prepared core body raw meal balls into the ball forming pan, add the shell raw materials prepared in step 2) while adding water, so that the core body is continuously rolled on the ball forming pan ...

[0037] Implementation steps of a method for preparing solid waste hollow ceramsite:

[0038]1) Preparation of hollow ceramsite core: Fully mix 7 parts of waste wood chips and 2 parts of filter press sludge by weight, and roll it into a ball in a ball-forming disc as a core, and the diameter of the core is 3-10mm:

[0039] The wood chips are about 200 meshes, which are produced during the process of making the base material of the wood-based company into products, and the wood chips contain a large amount of phenolic resin glue; ~90% water and a lot of organic matter;

[0040] 2) Pretreatment of shell raw materials: Mix ceramsite shell raw materials according to the weight ratio of 9 parts of fly ash and 1 part of sludge, and mix them well: Fly ash is the solid waste generated by the thermal power company, and its grade is II to III. .

[0041] 3) Preparation of ceramsite raw material balls: put the prepared ceramsite core raw material balls into the ball forming tray, add th...

Abstract

The invention belongs to the field of materials, and in particular relates to a solid waste hollow ceramsite and a preparation method thereof. The present invention simultaneously solves the problems of difficult solid waste pollution, high bulk density of solid waste ceramsite, small internal porosity, and large thermal conductivity by synergistically treating various solid wastes such as fly ash, filter press sludge, and waste wood chips. The hollow ceramsite produced by the method of the invention can be widely used in building thermal insulation materials, agricultural and gardening fertilizer storage carriers, etc. In addition, the invention has simple process, energy saving and environmental protection, and broad application prospect.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a solid waste hollow ceramsite and a preparation method thereof. Background technique [0002] With the rapid development of society and economy, the collection and treatment rate and treatment depth of industrial sewage and domestic sewage have been continuously improved, and the sludge production is also increasing sharply at a rate of about 10% per year. The filter press sludge in sewage treatment contains organic matter and a large amount of inorganic matter (mainly silicon, aluminum, iron, calcium, etc.) Sludge reduction and harmlessness, as well as resource utilization, have gradually become the research hotspot and development direction in the field of sludge treatment in recent years. [0003] In addition, fly ash is also one of the largest industrial waste residues in my country. With the development of the power industry, the fly ash emissions from coal-fired power plants are ...
