Description

PURIFYING SYSTEM AND METHOD OF POLLUTANTS DISCHARGING FROM WASTE PLASTICS EMULSIFICATION PLANT

The present invention relates to a system and method for purifying pollutants discharged from a waste resin emulsification plant, and it is possible to remove pollutants contained in combustion gas generated while heating the waste resin, and to heat the waste resin while heating the waste resin before melting the waste water. It relates to a pollutant purification system and purification method capable of separately collecting and purifying water vapor evaporated from the ground.

In general, synthetic resins called plastics are easy to mold and polymerize various substances with petroleum as the main raw material, so that the use of the synthetic resins is rapidly increased as the properties required by users are easy to be given. Treatment is emerging as a social problem.

Currently, most of this large amount of waste resin is treated by incineration and landfill, and only part of it is recycled. Because incineration and landfill eventually lead to environmental pollution due to the nature of not being easily decomposed, recycling is recommended. It is being considered as a major method of paper recycling.

In particular, as the oil reserves, which are fuels used to produce resin products, are reduced and the prices are rising, research is being actively conducted to reduce and recover oil components existing in waste resins to increase the degree of resource recycling.

As a conventional method of recovering other resources from the collected waste resin, there is a method of extracting oil from waste plastics through heat treatment, or crushing the waste into small pieces and mixing it with other materials to form a solid fuel rod by compression and molding.

However, the former has a problem of low economic feasibility and low quality of regenerated oil because the actual profit recovered is low compared to the input regeneration cost.

In addition, in the past, waste plastics were relatively easy to recycle as simple PP and PE materials, but in recent years, as plastic manufacturing technology has advanced, various functional materials such as PET, ABS, PC, PA, PBT, PPSU, and PCALLOY are used in addition to simple PP and PE. Therefore, the recycling process is difficult.

In particular, containers and films exposed to sunlight are coated with PVC using UV, silane crosslinking is added to containers and films requiring heat resistance and strength improvement, and various packaging papers are printed and coated with PVC, PET, PA, etc. Therefore, the advancement of plastic production technology has reduced the amount of recyclable waste plastics.

Accordingly, there is a method of dissolving and decomposing RDF and SRF types of waste plastics in half and using them as fuel in cement plants or cogeneration plants. Since it contains pollutants, it was difficult to purify these pollutants, and the cost was considerable, which eventually lowered the business feasibility of recycling waste resin.

Also, when heat is applied to melt the waste resin, water vapor is generated. This water vapor is generated by evaporation of moisture attached to the waste resin, and since it may contain contaminants and may cause odor, purification thereof is required. Conventionally, while emulsifying the waste resin, water vapor is also collected, and the waste water generated by cooling the water vapor is treated in a separate purification facility. Normally, when 1 ton of waste resin is treated, 150 kg of waste water is generated, and the treatment cost per ton of waste water is about 280,000 won, which greatly deteriorated the economic feasibility of recycling waste resin.

As shown, the pollutant purification system discharged from the waste resin emulsification plant according to the present invention purifies pollutants including water vapor and combustion gas generated while emulsifying the waste resin through deodorization, desulfurization, and desalination to discharge into the atmosphere. It relates to a device for the purpose, and is largely configured to include a steam exhaust unit 10 , a dust collector 30 , a connecting pipe 40 , and a reactor 50 .

First, the system for emulsifying waste resin will be described as follows. The system for emulsifying the waste resin may be a system well known in the prior art, but in this embodiment, the present applicant intends to explain based on the contents of the PCT application (PCT/KR2019/016449) filed on November 27, 2019.

Here, water vapor is generated by evaporating moisture attached to the waste resin, and since it may contain contaminants and may cause odor, purification thereof is required. Conventionally, while emulsifying the waste resin, water vapor is also collected, and the waste water generated by cooling the water vapor is treated in a separate purification facility. Normally, when 1 ton of waste resin is treated, 150 kg of waste water is generated, and the treatment cost per ton of waste water is about 280,000 won, which greatly deteriorated the economic feasibility of recycling waste resin.

That is, the steam heating tube 10b heats the steam flowing into the steam heating tube 10b to a higher temperature by the thermal decomposition furnace 1, so that the odor contained in the steam is removed due to the heat. In this embodiment, the steam heating tube 10b is arranged to surround the first inner body 2 from the inside of the first outer body 4 and is configured to extend into the first gas discharge tube 5. However, as long as the steam heating tube 10b is configured to be heated while staying inside the first external body 4 for a certain period of time, other configurations may be adopted.

As described above, when the first valve 13 is blocked and the second valve 23 is opened so that water other than steam flows into the steam heating tube 10b, the water is heated while flowing into the pyrolysis furnace 1 . It is evaporated into steam and flows out from the steam heating tube 10b.

Here, when the steam heating tube 10b is disposed inside the first gas discharge pipe 5, the steam passing through the steam heating tube 10b is cooled through the heat of the combustion gas discharged through the first gas discharge pipe 5. to prevent it from happening. Accordingly, the steam heating tube 10b is disposed and extended inside the first gas discharge pipe 5, and is branched from the first gas discharge pipe 5 in proximity to the connection pipe 40 and is connected to the middle of the connection pipe 40 do.

It includes a second valve 23 mounted on the.

One end of the dust collector 30 is connected to the first gas discharge pipe 5 to collect pollutants contained in the combustion gas exhausted through the first gas discharge pipe 5 . That is, the combustion gas generated during combustion by the first burner 3 contains odor, dust, sulfur dioxide and chlorine gas, and the dust collector 30 is installed to remove them and prevent environmental pollution.

A desulfurization chamber 31 in which solid sodium hydroxide 31c for desulfurization of combustion gas is disposed at one end of the dust collector 30, and an activated carbon 32c for deodorization and dust removal of combustion gas at the other end is disposed in a deodorization chamber It consists of (32).

The configuration of the dust collector 30 can be made variously, and as an example, as shown in FIG. 2 , the solid sodium hydroxide 31c and the activated carbon 32c are in the desulfurization chamber 31 and the deodorization chamber 32, respectively. It is arranged in a multi-stage structure, and may be arranged on the supporting wire mesh (31a, 32a) and the SUS wire mesh (31b, 32b). SUS wire mesh (31b, 32b) is made of about 60 ~ 100mesh, solid sodium hydroxide (31c) is installed on the SUS wire mesh (31b) to a thickness of about 5 cm, and activated carbon (32c) is installed to a thickness of about 10 cm.

The connection pipe 40 serves to mix the combustion gas that has passed through the dust collector 30 and the water vapor that has passed through the pyrolysis furnace 1 and introduce them into the reactor 50, and one end passes through the dust collector 30. It is connected to the other end of the dust collector 30 so that one combustion gas is introduced, and the middle end is connected to the steam heating tube 10b so that the combustion gas and water vapor are mixed and discharged to the other end.

The reactor 50 introduces combustion gas and water vapor to induce a desalination reaction in which the chlorine gas contained in the combustion gas is removed by reacting the combustion gas and water vapor with zinc in a heated high-temperature atmosphere. At this time, the high-temperature atmosphere and water vapor act to promote the reaction between the combustion gas and zinc.

The reactor 50 is connected to the connection pipe 40 so that the mixed combustion gas and water vapor are introduced, and a second gas discharge pipe 52 is disposed thereon, and is internal to react with the mixed combustion gas and water vapor. A second inner body 51 in which the zinc ruled 53 is located, a second burner 54 disposed below the second inner body 51 to heat the second body, and the second inner body A second outer body (55) for introducing heat from the second burner (54) while enclosing (51) is provided.

And the second gas discharge pipe 52 is equipped with a blower 60 for inducing a flow of air to discharge the hydrogen gas and water vapor finally produced by reaction in the reactor 50 to the atmosphere.

The operation of the pollutant purification system discharged from the waste resin emulsification plant described above will be described along with the pollutant purification method as follows.

3 is a flowchart illustrating a pollutant purification method according to the present invention, FIG. 4 is a diagram showing the operation of the pollutant purification system before oil vapor is generated, and FIG. 5 is an operation of the pollutant purification system after oil vapor is generated is a diagram showing

As shown in Fig. 4, when waste resin is put into the inside of the first internal body 2 and heated with a flame of 800 to 900° C. with the first burner 3, the temperature inside the first internal body 2 is gradually increased. Therefore, when it exceeds 100℃, the moisture in the waste resin evaporates and becomes water vapor. This steam is sucked into the steam intake pipe 10a and discharged from the first inner body 2 . Water vapor is absorbed by the adsorber 11 mounted on the water vapor intake pipe 10a.

The discharged water vapor is heated to a higher temperature and reheated by the first burner 3 to remove the odor. For this purpose, it is not mixed with the combustion gas inside the first outer body 4 surrounding the first inner body 2 It is further heated by inducing it to the inside of the first external body 4 through a steam heating tube 10b connected to the steam intake pipe 10a to prevent the heat from occurring.

On the other hand, when the temperature of the first internal body 2 increases by the first burner 3 and reaches approximately 150° C., the plastic with a low melting point is melted and oil vapor is generated, and this oil vapor is 10a). As such, when oil vapor is included in the water vapor discharged to the outside of the first inner body 2, the oil vapor is sensed, and as shown in FIG. 5, the water vapor intake pipe 10a is closed to close the first inner Block the discharge of oil vapor to the outside of the body (2). This action is performed by the gas detector 12 and the first valve 13 mounted on the steam intake pipe 10a.

When the first valve 13 is blocked and the oil vapor discharge is blocked, as a result, the inflow of water vapor into the water vapor intake pipe 10a is also blocked. Such water vapor is not only an object of purification, but also a substance that promotes the demineralization reaction with zinc in the combustion gas in a later stage. Accordingly, the second valve 23 installed in the water supply pipe 22 is opened, and the water stored in the water tank 21 flows into the steam intake pipe 10a, and through the steam heating pipe 10b connected thereto, the pyrolysis furnace 1 ) is evaporated to water vapor and fed to the next step.

And the combustion gas discharged from the first external body 4 is connected to the dust collector 30 through the first gas discharge pipe 5 and is deodorized, dust removed and desulfurized while passing through the dust collector 30 . The dust collector 30 is composed of a desulfurization chamber 31 in which solid sodium hydroxide 31c is disposed and a deodorization chamber 32 in which activated carbon 32c is disposed. is removed

Sulfur dioxide, as shown in Formula 1 below, and is reacted with oxygen SO _3, SO ₃ is as shown in [formula 2], the reaction water (H ₂ O) and is in H ₂ SO _4, H ₂ SO _{4 is converted into non-toxic sodium sulfate (Na 2} SO ₄ ) and water (H ₂ O) by reacting with sodium hydroxide in a desulfurization chamber, as shown in [Formula 3].

The gas introduced into the desulfurization chamber 31 from the dust collector 30 passes through the solid sodium hydroxide 31c installed on the SUS wire mesh 31b and flows into the deodorization chamber 32 through the lower end, and rises while ascending the SUS wire mesh 32b ) is discharged after passing through the activated carbon (32c) installed above.

The combustion gas deodorized and desulfurized through the dust collector 30 and the steam discharged from the steam heating tube 10b are mixed and introduced into the reactor. In the high-temperature atmosphere inside the reactor, the chlorine gas contained in the combustion gas is Removal reaction takes place. In the reactor, the zinc flake 53 is disposed and reacts with the combustion gas, and in order to promote this reaction, an atmosphere of high temperature (about 240° C.) and water vapor are required.

In the reactor, the combustion gas is desalted and converted into hydrogen gas, and these hydrogen gas and water vapor are discharged into the atmosphere in a state where pollutants are purified. To explain the desalination process in combustion gas in more detail, chlorine contained in the combustion gas reacts with water vapor to become hydrochloric acid, and hydrochloric acid reacts with zinc in a high-temperature atmosphere as shown in [Formula 4] to produce zinc chloride and hydrogen. . At this time, the generated hydrogen gas is discharged to the outside together with unreacted water vapor. Here, hydrogen is generated by the reaction of hydrochloric acid gas with zinc, and a certain temperature is required for zinc in the process of the reaction of zinc into zinc chloride, so as shown in FIG. If the density of hydrogen is low, although not shown, a direct heating method of directly heating a container containing zinc may be used.
