Description

A tea treatment device capable of separating and discharging tea and foreign substances and a continuous waste synthetic resin pyrolysis treatment facility including the same

The present invention relates to a tea treatment device capable of separating and discharging tea and foreign substances and a continuous waste synthetic resin pyrolysis treatment facility including the same. More specifically, the present invention relates to a continuous waste synthetic resin pyrolysis treatment facility that automatically and continuously performs the entire process of inputting, stirring, compressing, and supplying waste synthetic resin. The pyrolysis residues are compressed and transported in multiple stages. In particular, gas leakage caused by the pyrolysis residues can be blocked through a two-stage screw tilted upward. In the process of transferring the pyrolysis residues, holes of different sizes are drilled. It relates to a tea treatment device capable of selectively separating and discharging tea and foreign substances through each filter and a continuous waste synthetic resin pyrolysis treatment facility including the same.

Products made of synthetic resin, such as tires, vinyl, and plastic, which are widely used in various industrial fields and daily life, are recycled after use, and most are classified as waste and are landfilled or incinerated. These synthetic resin wastes are considerably larger in volume compared to their weight, so not only are landfill costs greater than regular waste, but they do not rot even when landfilled, so they are considered a social nuisance.

Recently, as a way to recycle synthetic resin waste without incinerating or landfilling it, research and development of emulsification methods and devices that can obtain useful oil by pyrolyzing synthetic resin waste has been actively conducted.

Conventionally, waste synthetic resin had to be added manually, so each time the material was added, the pyrolysis treatment device was stopped and a certain period of time passed before the material was added. This caused not only the inconvenience caused by adding the material, but also extremely low work efficiency. Because there are many problems, such as a significant decrease in productivity, there is a need to develop technology that can continuously operate the device and automatically input materials.

Accordingly, in the current pyrolysis treatment facility, a method of sequentially pyrolyzing waste through a plurality of transfer screws has been proposed. However, this pyrolysis device cannot increase the temperature at each stage, so the firebox temperature must be increased by increasing the supply heat source gas, so it has a large capacity. A burner was required, and there was a problem of clogging of the oil vapor duct and a large amount of tar being generated from the produced oil.

Meanwhile, in order to reintroduce tea with recycling value into the pyrolysis treatment device among the pyrolysis residues generated during pyrolysis, it is necessary to separate and discharge the char and foreign substances within the pyrolysis residue. There is a need for automated equipment processes to do this.

FIG. 2 is a diagram showing the overall configuration of a continuous waste synthetic resin pyrolysis treatment facility 200 including a tea treatment device capable of separating and discharging tea and foreign substances shown in FIG. 1.

Below, preferred embodiments are presented to aid understanding of the present invention. However, the following examples are provided only to make the present invention easier to understand, and the content of the present invention is not limited by the examples.

Figure 1 is a diagram showing the configuration of a tea processing device 100 capable of separating and discharging tea and foreign substances according to an embodiment of the present invention.

Looking at Figure 1, the tea processing device 100 capable of separating and discharging tea and foreign substances according to an embodiment of the present invention is connected in communication with the end of the pyrolysis treatment transfer screw conveyor provided in the pyrolysis treatment device, and rotates in one direction. The first residue treatment transfer screw conveyor 110, which compresses and transports pyrolysis residues (including char and various foreign substances (non-ferrous, etc.)), is connected in communication with the end of the first residue treatment transfer screw conveyor 110, but is connected upward. The second residue treatment transfer screw conveyor (120) is inclined at an angle of 45 degrees and rotates in one direction to further compress and transfer the previously transferred pyrolysis residue, the lower side of the distal end of the second residue treatment transfer screw conveyor (120) It is connected in a vertical direction with the tea collection device 130, which preferentially separates, discharges, and collects Char from the pyrolysis residues, and the lower side of the distal end of the second residue treatment transfer screw conveyor 120. It may be configured to include a foreign matter collection device 140 that collects foreign matter that has not been separated and discharged through the car collection device 130.

The first residue treatment transfer screw conveyor 110 includes a transfer screw blade that rotates in one direction within a horizontal communication tube formed long in the longitudinal direction, and may be connected to the end portion of the pyrolysis treatment transfer screw conveyor provided in the pyrolysis treatment apparatus. At this time, as the transfer screw blade rotates in one direction, the tea and foreign substances, which are pyrolysis residues, are gradually compressed and transferred in the direction of the second residue treatment transfer screw conveyor 120 corresponding to the rotation direction of the transfer screw blade.

One side of the second residue treatment transfer screw conveyor 120 is connected in communication with the distal end of the first residue treatment transfer screw conveyor 110, and at this time, it is tilted upward at an angle of 45 degrees or more. In other words, since the discharge area of the second residual material treatment transfer conveyor 120 is located at a higher level, the gas generated from the residual material and the foreign materials compressed inside can be naturally discharged upward, resulting in a gas leak blocking effect. You can have .

In addition, the second residue treatment transfer screw conveyor 120 also includes a transfer screw blade on the inside like the first residue treatment transfer screw conveyor 110. At this time, the rotational speed of the transfer screw blade is adjusted to the first residue treatment transfer screw conveyor. It can be adjusted according to the current value generated when compressing the pyrolysis residue through (110). At this time, the current value generated when compressing the pyrolysis residue through the first residue treatment transfer screw conveyor 110 may vary depending on the quality of the tea produced after pyrolysis, and accordingly, the current value of the second residue treatment transfer screw conveyor 110 Continuous discharge operation is possible by automatically adjusting the transfer screw blade rotation speed.

The tea collection device 130 is connected in a vertical direction to the lower side of the distal end of the second residue treatment transfer screw conveyor 120. At this time, the area connected to the second residue treatment transfer screw conveyor 120 is open, so the second residue treatment transfer screw conveyor 120 is connected to the second residue treatment transfer screw conveyor 120. Tea and foreign substances transported along the residual material treatment transfer screw conveyor 120 can fall to the bottom and be collected through this. At this time, the tea collection device 130 is equipped with a strainer 131 for separating and discharging tea, which has at least 20 holes of 20 mm in size, large enough to allow tea particles to pass, so that only tea can be separated and collected. It can be.

The strainer 131 for separating and discharging tea has a shape corresponding to the lower side of the second residue treatment transfer screw conveyor 120, and has at least 20 holes of 20 mm in size, so that relatively small size can be filtered through the holes. The car is discharged separately first. Since both sides of this filter 131 for separating and discharging tea can be formed identically, if replacement is necessary, it can be turned and applied to both sides.

A foreign matter collecting device 140 is provided on one side of the tea collecting device 130. The foreign matter collection device 140 is connected in a vertical direction to the lower side of the area more adjacent to the distal end of the second residue treatment transfer screw conveyor 120, and is used to transport tea and foreign matter along the second residue treatment transfer screw conveyor 120. Since the tea has already been separated and discharged through the tea strainer 131, foreign substances (non-ferrous, etc.) that are transported without being separated may fall to the bottom and be collected.

On the other hand, the present invention is an automatic discharge unit ( (not shown) may be further included. When the collected amount of cars and foreign substances exceeds a preset standard value, the automatic discharge unit sprays air in the direction toward the discharge parts of the car collection device 130 and the foreign matter collection device 140, so that the cars and foreign substances are discharged to the outside.

Next, we will look at the overall configuration of the continuous waste synthetic resin pyrolysis treatment facility 200, which includes the tea treatment device capable of separating and discharging tea and foreign substances as discussed above.

FIG. 2 is a diagram showing the overall configuration of a continuous waste synthetic resin pyrolysis treatment facility 200 including a tea treatment device capable of separating and discharging tea and foreign substances shown in FIG. 1.

Looking at FIG. 2, the continuous waste synthetic resin pyrolysis treatment facility 200 including an oil flushing device largely includes a waste synthetic resin input unit 210, a pyrolysis treatment unit 220, a tea treatment unit 230, an oil vapor heat exchange unit 240, It may be configured to include an oil processing unit 250 and a gas processing unit 260.

The waste synthetic resin inlet 210 is largely comprised of an articulated crane 211 for injecting the waste synthetic resin, a hopper 212 for receiving the injected waste synthetic resin, and a machine installed in the longitudinal direction within the hopper 212 to stir the injected waste synthetic resin. A pair of stirring screws 213, a pair of compression screws 214 installed in the longitudinal direction at the lower side of the hopper 212 and supplying and simultaneously compressing the stirred waste synthetic resin in one direction, the pair of compression screws A pair of vertical stirring screws 215 and each vertical stirring screw are installed to be connected in a vertical direction at one end of (214), and transport the waste synthetic resin to the lower side and simultaneously release the waste synthetic resin in a compressed state. It is connected to (215) and may be configured to include a pair of supply screws (216) that supply the transferred waste synthetic resin to the pyrolysis transfer path.

The articulation crane 211 can be a three-stage articulation crane for the smooth introduction, packaging, storage, and loading of waste synthetic resin, which is the main raw material, into the hopper 212, and can be installed so that the working radius is 9.5 m.

The hopper 212 serves to accommodate a large amount of waste synthetic resin introduced through the articulated crane 211, and can be formed in an upper and lower shape with the upper and lower parts open. In addition, a pair of stirring screws 213 may be provided inside the longitudinal direction, and the waste synthetic resin is discharged through a pair of open areas provided on the lower side. At this time, each open area has a pair of compression screws. A screw 214 is provided.

A pair of stirring screws 213 serve to agitate a large amount of waste synthetic resin introduced into the hopper 212. At this time, the stirring drive motor, the stirring shaft that rotates by being coupled to the rotation axis of the stirring drive motor, and the outer peripheral surface of the stirring shaft It may be configured to include a spiral stirring blade provided along. The pair of stirring screws 213 can be more easily compressed through the pair of compression screws 214 by breaking or loosening a large amount of waste synthetic resin input into the hopper 212 if it is lumped or pressed. Let it be.

Meanwhile, the pair of stirring screws 213 are installed parallel to each other while maintaining a certain distance (for example, 150 mm) from each other within the hopper 212, and at this time, the compression of the pair of compression screws 214 It rotates in the direction opposite to the direction (direction of rotation).

A pair of compression screws 214 are provided below a pair of open areas provided in the longitudinal direction (lengthwise) at the bottom of the hopper 120, and supply waste synthetic resin discharged through the pair of open areas in one direction. At the same time, it serves to compress the waste synthetic resin.

This pair of compression screws 214 is a pair of conveyor ducts (or conveyor pipes) communicating with a pair of open areas provided in the lower part of the hopper 212, and a pair of compression drives provided in the pair of conveyor ducts. It may be configured to include a motor, a rotation shaft coupled to the rotation axis of the compression drive motor and extending in the longitudinal direction of the conveyor duct, and a compression screw provided along the outer peripheral surface of the rotation shaft.

At this time, the compression screw transfers the waste synthetic resin in the rotational direction through its spiral structure, and the pitch may be gradually narrowed based on the transfer direction. Accordingly, the compression efficiency through the pair of compression screws 214 can be increased by increasing the conveying speed due to the narrowing pitch.

The waste synthetic resin compressed and transferred through a pair of compression screws 214 is transferred to a pair of vertical stirring screws 215.

A pair of vertical stirring screws 215 are installed to be connected in the vertical direction at one end of the pair of compression screws 214, and simultaneously transport the conveyed waste synthetic resin in a downward direction. It plays a role in releasing the compressed waste synthetic resin.

The pair of supply screws 216 are each connected to the lower part of the vertical stirring screw 215, and serve to supply the waste synthetic resin transferred through the pair of vertical stirring screws 150 to the pyrolysis transfer path.

Meanwhile, although not shown in the drawing, the present invention may further include a catalyst input unit (not shown). The catalyst introduced through the catalyst inlet is preferably zeolite, and more preferably slaked lime (calcium hydroxide). This is to reduce the cost of catalyst input.

Additionally, zeolite or slaked lime may be used as the catalyst. At this time, the zeolite contains SiO2 62.2-75.0 wt%, Al2O2 10.0-21.0 wt%, Na2O 1.5-5.0 wt%, K2O 1.7-3.5 wt%, CaO 0.8-2.5 wt%, Fe2O2 0.5-1.8 wt%, and 0.5 wt% of other components. It contains ~1.8 wt%, and the loss on ignition is 5.2~15.3 wt%, and other components may include FeO, TiO2, P2O5, and MnO. Additionally, the pH of the zeolite may be 9.0 to 10.5, and the cation exchange capacity (CEC) may be 80 to 92 meq/100g. Slaked lime may contain more than 70% of CaO, less than 2% of SiO2, less than 3% of MgO, less than 1% of Fe2O3, and less than 1% of Al2O3, and preferably does not contain sulfur.

In addition, the slaked lime has a particle size that allows more than 95% of the slaked lime to pass through a 325 mesh sieve. Specifically, it is desirable to have a particle size that allows 96.58% of the slaked lime to pass through a 325 mesh sieve.

Here, when zeolite is used as the catalyst, the formation of suspended substances such as tar, which is generated when oil vapor is generated, is suppressed while making it easy to remove suspended substances such as tar, and when slaked lime is used as the catalyst, it is a strong alkali component to remove oil vapor. It is easy to suppress the formation of suspended substances such as tar and remove suspended substances such as tar, which are generated at the same time, and can easily neutralize the produced oil.

The pyrolysis treatment unit 220 transfers the waste synthetic resin input through the waste synthetic resin input unit 210 to one side and performs pyrolysis treatment multiple times, thereby allowing oil vapor and oil to be discharged.

More specifically, the pyrolysis treatment unit 220 is a device that performs pyrolysis of the input waste synthetic resin by transferring it in stages according to changes in the rotation speed of an automatically controlled screw. It receives the waste synthetic resin from the waste synthetic resin input unit 210 and decomposes the waste synthetic resin into waste synthetic resin. It is configured to include a multi-stage pyrolysis transfer screw conveyor to generate oil vapor by pyrolyzing the oil.

Here, the temperature of the pyrolysis processing unit 220 is automatically adjusted through automatic adjustment of the gas pressure according to the internal temperature of the pyrolysis reactor body set to control the yield of oil and gas, and a pair of first to fourth pyrolysis treatments are transferred. The screw conveyor performs thermal decomposition by automatically proportionally controlling the rotation speed according to the set values of current (current value) and temperature (outlet oil vapor temperature), and automatically transfers the generated oil vapor and cooled oil to the subsequent process.

In addition, the internal temperature of the pyrolysis reactor main body of the pyrolysis processing unit 220 is automatically adjusted. Considering that if the temperature inside the pyrolysis reactor main body is kept high, pyrolysis occurs well and the amount of gas generated increases, and if it is kept low, the oil production amount increases. , the operating temperature is set according to the quality (e.g., moisture content) of the input fuel, and in order to automatically maintain this set temperature, the gas pressure set value of the gas burner gas supply tank for supplying gas to the gas burner is used as a numerical control function. It is automatically changed so that the internal temperature of the pyrolysis reactor main body is automatically and consistently adjusted.

The tea treatment unit 230 serves to compress and process the pyrolysis residue, Char, discharged from the pyrolysis treatment unit 220. Through this compression, the discharge of oil vapor is blocked and only the tea is automatically discharged to the outside. Since this tea processing unit 230 corresponds to the tea processing device 100 that can separate and discharge tea and foreign substances discussed above, detailed description will be omitted.
