Description

Continuous input device of tunnel type synthetic resin non-catalytic pyrolysis oil regeneration system {SERIAL INJECTION DEVICE FOR WASTE PLASTICS PYCLYSIS RECYCLE SYSTEM}

The present invention relates to a continuous input device of a waste synthetic resin pyrolysis oil regeneration system, and more particularly, to continuously input the waste synthetic resin from which air is removed to a regeneration furnace provided in the waste synthetic resin pyrolysis oil regeneration system.

In recent years, plastic production and consumption have increased greatly due to the rapid development of the plastics industry and the increase of industrial activities. In particular, the waste plastics have increased significantly after the pay-as-you-go and separate collection, while the recycling rate is low. Treatment is becoming a social issue.

In general, the disposal of waste plastics depends on incineration or landfill, but incineration releases harmful substances such as dioxins, which causes environmental pollution, and landfilling causes instability of the ground due to lack of landfills and the non-corrosive nature of plastics. In order to solve these problems, the technology for reducing the environmental pollution, and the recovery of fuel oil or petroleum resources by pyrolysis in terms of recycling of resources has attracted attention.

The above pyrolysis technology is to decompose wastes by heating them to a high temperature in an oxygen-free or low-oxygen atmosphere. The high-carbon compound having long carbon chains is reduced and decomposed in the absence of oxygen to lower various organic compounds. Depending on the form of the compound, it may be a gas or a liquid, and this material is a technology for maintaining the properties similar to petroleum-based compounds so that they can be reused as fuel for combustion.

Such wastes may include organic chemicals having carbon chains. The most commonly used wastes are high-molecular waste plastics, and the first reason for thermal decomposition of polymer wastes is the condition and degree. Although it is different, it is easily decomposed when heat is applied. Second, even if toxic substances are generated, they are generated in pure form or have relatively low air ratio, so they are relatively easy to process. Third, they attempt to reduce the polymer waste to the original low molecular weight materials. This is because an expensive raw material such as a monomer can be recovered and at least a high calorific value of combustion gas or oil can be recovered.

Therefore, as a solution to this problem, a waste synthetic resin pyrolysis oil regeneration system capable of obtaining pyrolysis oil by condensing gas vaporized by thermal decomposition of waste synthetic resin has been proposed, but such a conventional waste synthetic resin pyrolysis oil regeneration system is a waste synthetic resin material. Because it is necessary to put it in manually, the material is put in the state after a certain time has elapsed after stopping the operation of the pyrolysis furnace every time the material is put in. Because of the many problems, the development of a device capable of automatically injecting materials while continuously operating the device was desired.

The present invention has been made to solve the above problems, it is possible to continuously input the waste synthetic resin with air removed to the regeneration furnace provided in the waste synthetic resin pyrolysis oil regeneration system to enable continuous operation of the device Therefore, the purpose of the present invention is to provide a continuous input device of waste synthetic resin pyrolysis oil regeneration system that can maximize productivity by improving work efficiency and minimize the workforce and greatly reduce the cost of regeneration. .

An injection hopper 34 is installed vertically, and a pair of shutters 36 which are opened and closed to block the inflow of air during the injection of waste synthetic resin are usually installed on the upper portion of the injection hopper 34. That is, the shutter 36 is slidably opened and closed by the normal opening and closing means as anyone can see. The pair of shutters 36 are operated by the normal opening and closing means when closing the waste synthetic resin in the injection hopper 34 toward the regeneration furnace 30 to close the upper portion of the injection hopper 34, and furthermore, When the waste synthetic resin is introduced into the hopper 34 under the state in which 30) is closed, it is opened by a normal opening and closing means.
