Definitions

  • the invention relates to a process for recovering waste paper pulp (treatment mud) to be formed as a result of the paper production process in the paper and cardboard production industry by dehydration and drying it and a method of manufacturing variety of products with the raw material gained in this process such as an egg shell, a laminate parquet, a corrugated board, a facade covering, a chipboard and chipboard replacing product, a plasterboard and plasterboard replacement product, or a furniture material such as a table, a chair etc.
  • the moisture content of the waste pulp formed in the present application (03 03 07 coded mechanically separated scraps during the transformation of the waste paper and carton into pulp) is around 40-50% in a dehydration process using only decanter centrifuge and around 70-80% in a dehydration process using filter press.
  • condensation and dehydration processes are required in order to eliminate the pulp with low cost.
  • Paper pulp dehydration equipment applied for paper industries in our country is mostly decanter centrifuge, and less likely is filter press. Due to the high operating costs, operator need to follow the system and manpower required, enterprises do not prefer filter press application.
  • the use of decanter centrifuge has a high initial investment cost. In both applications, the existing pulp of waste paper can not reach the desired efficiency of dryness.
  • the paper pulp dehydrated around 40-50% with the decanter centrifuge, or around 70-80% with the filter press is sent to the cement factories or disposal plants. Waste paper pulp sent to disposal plants and cement factories brings an additional cost to the operation.
  • Waste paper pulp is given to the furnace for cement construction along with limestone, clay and marl from the feeding chamber called the first crusher.
  • the wastes and raw materials fed to the furnace constitute the clinker, which is the raw material of the cement. This means that waste is used as a support for internal combustion in the construction of cement and cause damage to the environment along with the emissions from the chimney.
  • the disposal plants are drying the treatment sludge with heat.
  • the dried material is sent to cement factories. Dried pulp brought to the cement factory is used in the production of clinker by feeding from the second crusher to the furnace.
  • the application no. 2010/07661 encountered in technical research is related to the production method of waste paper compound brick.
  • paper or waste paper as the main material in the mortar composition of the brick construction on the subject of invention.
  • the existing structure does not have a new innovation in the transformation of waste paper pulp into various products, which aims to solve the above-mentioned disadvantages and will be produced as a result of the recycling of waste paper pulp by dehydration and drying.
  • the Purpose of Invention is inspired by the existing circumstances and aims to solve the above- mentioned drawbacks.
  • Figure 1 is a schematic illustration of the factory area where the method of the invention is performed.
  • Figure 2 is a diagram showing the flowchart of anhydrous alternative method of the invention.
  • FIG. 3 is a diagram showing the flowchart of hydrous alternative method of the invention.
  • the invention relates to a method for recovering waste paper pulp (treatment mud) to be produced as a result of the paper production process in the paper and cardboard manufacturing industry by dehydration and drying, and converting the raw material to be produced as a result of such recycling into various products.
  • the products mentioned are; an egg shell, a laminate parquet, a corrugated board, a facade covering, a chipboard and chipboard replacing product, a plasterboard and plasterboard replacement product, or furniture materials to produce a table, a chair etc.
  • the process steps of the method of the invention are as follows;
  • the waste paper pulp formed as a result of paper production process is taken from the factories and brought to the factory where the application is made. Weighing of pulp is done by means of paper weigh and stored in temporary storage areas (1 ) until it is processed.
  • waste paper pulp By means of a feeder (2) located in the factory, the waste paper pulp is fed to the compressor (3).
  • the coarse water of waste paper pulp is taken with this compressor (3) mentioned at very low cost compared to the existing methods.
  • waste paper pulp can be solved by adding water and washing. During the extraction of the coarse water, the waste paper pulp is solved and the heavy metals in it are treated with the separated water.
  • the waste paper pulp, from which the coarse water is taken, comes through the conveyor belt (4) to the drying tunnel (5).
  • the waste paper pulp is passed through the drying tunnel (5), which is compatible with both solar energy usage and natural gas heating and is delivered in complete dryness. It is then passed through a breaker (6), crushed, thinned and transformed into raw material.
  • the waste paper pulp which has become a raw material is transported by conveyor belts (4), packaged and offered for sale.
  • the raw materials obtained are sold directly or after they are converted into the product by adding various chemicals such as coloring paint, hardener, various glue and adhesives to these raw materials, and after being pressed and packaged in desired thickness.
  • the end product such as an egg shell, a laminate parquet, a corrugated board, a facade covering, a chipboard and chipboard replacing product, a plasterboard and plasterboard replacement product, or furniture materials to produce a table, a chair etc. is achieved by adding products such as adhesives, hardeners, glue, coloring dyes, consistency regulators, then converted by joining and pouring into molds if desired.
  • This raw material, produced from waste paper pulp, is dehydrated and dried by 100% compared to the existing methods and then converted into product by adding various chemicals. Then, it can be pressed to used in desired thickness.
  • waste paper pulp from the first stage can be dissolved by adding 1 ton of water to 1 ton of waste paper pulp, then filtered and after that the same process can be applied by joining various chemicals. Then, the product is pressed in the desired thickness, and the recycling of these wastes is achieved.
  • the pulp of waste paper has been delivered to the full dryness, it is used as a dry raw material free of moisture content at high calorific value, without having to be mixed with other wastes with very high calorific value.
  • This material can also be sold as fuel for combustion in cement factories if desired.
