Description

[0001] The present invention relates to a pyrolysis processing unit using plant waste by waste heat,

More particularly, the present invention relates to an apparatus for pyrolysis of agricultural by-products using incineration cul- ture waste, and more particularly, to a pyrolysis apparatus for pyrolysis of agricultural waste by using waste heat generated in the incineration process of waste, It is an agricultural by-product pyrolysis treatment system that uses incineration waste heat to generate resources to replace existing fossil fuels such as gas and to reduce resource development costs.

Recently, there has been a growing interest in the environment, such as the abolition of carbon dioxide and the prohibition of marine dumping of byproducts and wastes generated after the combustion of fossil fuels such as coal. Especially, due to the exhaustion of fossil fuels and the risk of nuclear energy, There is a growing interest in biomass as an energy source.

Biomass refers to the amount of specific organisms present in any space in terms of weight or energy budget, which is sometimes called the amount of living organisms. The biomass produced on Earth is equivalent to the total reserves of petroleum, There is an advantage that it will not be exhausted if used.

Wood, which accounts for a large part of biomass, is easily obtained in powder form and is recognized as an energy source capable of replacing coal due to its high calorific value. Recently, it has been widely used in heating boilers for agricultural facilities. It has been actively promoted, and there has been much support from the government. However, due to the limited cost of wood resources and pulverization, the domestic price of raw materials has been raised. In the case of heating wood boilers, the influence of combustion gases in the combustion of wood powder causes many It causes problems and it is difficult to apply to the field.

As a raw material for biomass, water hyacinth is a perennial water goby ornamental plant originating in the tropics of the Americas, and is well known as a water purification plant in Korea. The water hyacinth is very fast-breeding plant that grows up to 752 individuals without water supply at 20 ℃ or more. It can be cultivated in reservoir from April to October in Korea. As a result of cultivation in the reservoir located in Yongin in 2009, it was possible to produce about 50 tons of building (dry matter; moisture content 0%) at 1 ha.

Therefore, it can be used as a good biomass to replace wood in terms of price, because it can secure a large amount of water hyacinth at a low cost by appropriately using the domestic water reservoir.

The leaves have also been used as a traditional firepower supply, but are now rarely used due to the supply of coal and oil. The fallen leaves that are generated in big cities in fall are collected and incinerated after collection. Therefore, it can be used as a very useful biomass source in addition to water hyacinth if the leaves are pyrolyzed and then used as fuel for combustion.

Pyrolysis is a treatment method for obtaining woody or liquid fuels such as gas or cracked oil and solid fuels such as tar or charcoal by heating woody biomass in the anoxic or hypoxic state at a temperature of 400 ° C to 1000 ° C.

However, since the pyrolysis apparatus for wood used in Europe and the United States is intended to recover the combustion gas and the charcoal liquid generated in the pyrolysis process by processing the wood into a plate of a predetermined size and pyrolyzing the plate, It is impossible to directly use it as pyrolysis device of herbaceous plant such as fallen leaves, agricultural byproducts.

Therefore, the inventor of the present invention has developed a pyrolysis apparatus for large-scale industrial use using herbaceous biomass resources and has been put into practical use through the patent registration No. 10-1231812. However, It is not efficient to use it.

That is, the working process of the conventional batch type pyrolysis apparatus is as follows: (1) putting the biomass into the pyrolysis apparatus -> (2) drying -> pyrolysis -> cooling and discharging -> In the conventional pyrolysis apparatus, since all the processes are arranged in a single tank body unit, in order to perform a new work process after completing one operation process, There is a problem in that it is not very efficient in terms of the utilization of the apparatus because the heater must wait for a long time until the heater is cooled. However, when the heater cooling process is neglected and the biomass feedstock is directly fed, the heat generation amount of the feedstock becomes uneven due to the unevenness of the temperature, which lowers the efficiency of the entire raw material utilization.

In order to overcome this problem, a large-capacity continuous pyrolysis apparatus has been developed through Patent Registration No. 10-1453326. However, pyrolysis due to overheating of the heater portion as a pyrolysis heat source has made it impossible to perform effective pyrolysis processing. There has been a problem.

The term used in the present invention is a general term that is widely used at present. However, in some cases, there is a term selected arbitrarily by the applicant. In this case, the term used in the present invention It is necessary to understand the meaning.

Hereinafter, the technical structure of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings. Here, the expressions related to the directions of up, down, right, left, right, left, and bottom are all based on the drawings presented unless otherwise specified.

In order to pyrolyze waterworms, fallen leaves, agricultural byproducts, etc. and utilize them as fuel resources, pyrolyzed fuel resources should have a calorific value at the level of coal and wood. However, since herbaceous raw materials such as water hyacinth, fallen leaves, and agricultural by-products have a lower calorific value than coal or wood, they remove components such as water in the anoxic state at a high temperature of 200 ° C to 500 ° C for 13 hours, Pyrolysis treatment is necessary to make hydrophobic carbonized pellets (biocoa). In the present invention, as shown in Table 1 below, it was confirmed that calorific value before and after pyrolysis treatment was previously tested, and that pyrolysis treatment of water hyacinth can replace wood in terms of calorific value.

Kinds Before processing After processing water hyacinth 3,053 kcal / kg 5,300 kcal / kg Leaves 3,000 kcal / kg 5,100 kcal / kg wood 4,000 kcal / kg 5,000 kcal / kg Coal Approximately 6,000 kcal / kg

<Comparison of calorific value before / after pyrolysis treatment>

Preliminary experiments using industrial electric furnace (Lab. Scale, throughput 100 g) showed that the raw water content, treatment temperature, treatment time, pressure and oxygen amount affect the heating value improvement during pyrolysis process. Especially, It has been found that the development of technologies and devices for maintaining the inside of anoxic and atmospheric pressure is indispensable.

Therefore, in the case of pyrolysis of water hyacinth, fallen leaves, agricultural byproducts, and recycling as combustion fuel, it is necessary to produce a large amount of fuel with high calorific value in order to be competitive with existing fuels such as coal, oil and gas.

For this purpose, the inside of pyrolysis tank should be in anoxic condition during pyrolysis process, and raw material should be input, pyrolysis and discharge simultaneously while maintaining pyrolysis temperature constant.

However, when the pyrolysis temperature is raised to 300 ° C or more by using an electric heater, ignition of nitrogen gas or the like is caused. In spite of continuous supply of gas, ignition occurs in the electric heater part, There is also a problem that only the electric heater portion is intensively heated and the whole of the input raw material is not uniformly pyrolyzed.

High temperature air (about 900 ℃ or higher) generated at incineration at a waste incinerator is supplied to the environmental treatment facility at 250 ℃ while steam and power generation process is performed in the boiler, and then discharged to the atmosphere through the chimney. As described above, when the pyrolysis process is performed using the high-temperature air generated in the incinerator or the like and released into the air, a considerable effect is expected from the viewpoint of energy recycling. In addition, there is no danger of ignition in the high temperature air generated after the incineration, and the temperature distribution can be easily controlled when the raw material is pyrolyzed by the flow of the hot air.

Therefore, it is expected to solve the problems of ignition of the conventional pyrolysis apparatus using the electric heater and complication of the process configuration due to the use of nitrogen gas for preventing ignition.

As shown in FIGS. 1 and 2, the agricultural by-product pyrolysis apparatus using the waste heat of the present invention mainly comprises a frame section 10 for supporting the pyrolysis tank main body 1, (B) formed at the bottom of the drying and preheating unit (A) to be pyrolysed, and a pyrolysis unit (B) formed at the bottom of the pyrolysis unit (B) And a cooling and discharging portion (C) for cooling and discharging the pyrolyzed high temperature raw material.

The drying and preheating part A includes a stirring device 3 and a rotation type opening and closing device 5 and the pyrolysis processing part B is formed at the bottom of the drying and preheating part A, The cooling and discharging unit C includes a screw conveyor 8 and an outlet 11 formed at the bottom of the thermal decomposition treatment unit B, The pyrolysis tank main body 1 is divided into the drying and preheating portion, the pyrolysis processing portion and the cooling and discharging portion by the rotary type opening and closing devices 5 and 9, respectively. The drying and preheating portion and the pyrolysis processing portion are provided at the incinerator A hot air inlet 15 for supplying the high temperature waste heat generated when the refuse is incinerated to the pyrolysis tank main body 1 and a hot air outlet 17 for discharging the supplied high temperature waste heat are formed respectively, Can be added.

That is, since the raw material introduced into the pyrolysis apparatus is to be transported to the lower part by its own weight while staying in the drying and preheating section, the pyrolysis processing section, the cooling and discharging section for the pyrolysis treatment time, The pyrolysis processing part B and the cooling and discharging part C are connected to the rotary type opening and closing device 5 and the processing part rotary type opening and closing device 9 ). &Lt; / RTI &gt;

Since the raw material to be loaded in the drying and preheating part A contains a larger amount of water than the raw material to be loaded in the pyrolysis processing part B, The volume of the drying and preheating portion (A) is formed to be larger than the volume of the pyrolysis processing portion (B).

The pyrolysis tank main body 1 is provided with a charging port 2 at an upper portion thereof and the frame portion 10 separates the pyrolysis main body 1 from the ground surface, (Not shown).

Food waste and agricultural byproduct resources pyrolyzed in the main body 1 are loaded into the raw material tank by their own weight through the inlet port 2 and put into the drying and preheating part A. The stacked raw material is uniformly stacked by the rotary type stirring device 3 with respect to the entire area of the tank, and a level meter 4 is formed in the tank main body near the stirring device 3, and is disposed inside the pyrolysis tank main body 1 The loading height of the loaded material is controlled at any time to maintain the proper amount.

In this case, various transporting means such as a screw conveyor and a belt conveyor can be applied to move the raw material to the charging port. The opening and closing of the charging port can be applied to a linear motion type or a rotary type. Various means can be used.

The dried and preheated raw material is transported by its own weight to the pyrolysis processing section (B) by the rotation of the rotary opening / closing device (5). The rotary opening and closing devices 5 and 9 for interrupting the drying and preheating part A and the pyrolysis processing part B can use various known means such as a linear motion type using a pneumatic cylinder 21 such as an oil pressure and an air cylinder have.

3, the rotary plate 51, which is applied to the rotary type opening and closing device 5 formed in the drying and preheating portion A, has a through hole 53 through which waste heat of high temperature can pass, , The through holes 53 can be easily moved in the high temperature waste heat which is moved from the lower side to the upper side and the raw material to be loaded on the rotary type opening and closing device is formed in a form of a supercritical state so as not to pass therethrough.

The hot air inlet port and the hot air outlet port are formed horizontally at regular intervals. The hot air inlet port and the hot air outlet port are alternately formed so that the high temperature waste heat discharged from the hot air inlet port is raised by the convection action, So that it can be discharged through the hot air outlet.

That is, when the raw material is supplied to the pyrolysis unit B, the high-temperature air supplied to the hot air inlet 15 is discharged to the lower portion of the charging port, and is transferred to the upper layer by the temperature difference while passing between the charged raw materials. 17) is installed to heat the loaded raw materials while moving between the loaded raw materials without being obstructed by the hot air charged in the lower part, so that the pyrolysis process can be carried out in a forced manner, and the heat generation amount It is important to keep the pyrolysis process temperature and time constant. Therefore, the hot air inlet 15 and the discharge port 17 are arranged in the tank so as to be located at the lower end, the middle portion, the upper end, So that the temperature inside the tank is uniformly maintained.

The hot air inlet 15 formed in the pyrolysis unit B is formed of an upper hot air inlet 15-1 and a lower hot air inlet 15-2 and a hot air outlet 17 is positioned between the upper and lower hot air inlet ports, and the upper hot air inlet port 15-1 is formed in the shape of a pipe passing through the pyrolysis tank main body part, (5) so that high temperature hot air can be injected between the raw materials loaded on the rotary type opening and closing device (5), and waste heat of high temperature is discharged through the raw materials loaded through the hot air inlet.

4, the hot air discharge port 17 formed in the pyrolysis unit B is formed in the form of a pipe passing through the pyrolysis tank main body, and an outlet for discharging the sucked waste heat is formed by the drying and preheating The waste heat is connected to the hot air inlet formed in the portion A and is recycled to the pyrolysis tank main body through the hot air inlet so as to recycle the waste heat.

The hot air inlet 15 is formed in the shape of a pipe passing through the pyrolysis tank main body portion. The hot air inlet that is buried in the loaded material among the hot air inlet 15 forms a plurality of discharge holes 153 on its outer surface The waste heat of high temperature can be effectively recycled between the raw materials loaded on the rotary type opening and closing apparatus by injecting high temperature waste heat between the raw materials to be loaded.

During the pyrolysis process, the rotary agitator (3) is rotated to uniformly pyrolyze the raw materials so that the raw materials are continuously mixed. The pyrolysis-treated raw material is transported by its own weight to the cooling and discharging portion C by the rotation of the processing portion rotary opening / closing device 9. [

The cooling and discharging portion C includes a rotary valve through which the raw material conveyed by the screw conveyor 8 is discharged and the conveyed raw material is discharged to the outside by the rotation of the rotary valve attached to the discharge port, Tight type rotary valve 13 to prevent the outside air from flowing into the body from the discharge port.

In order to monitor and control the heat treatment temperature inside the main body and the central part of the main body, a temperature sensing sensor 19 is provided at the lower end, the middle part and the upper end for each height in the wall surface part and the central part of the main body part, So that the total pyrolysis temperature can be precisely controlled.

The outside of the body is covered with a heat insulating material 20 to prevent heat loss. In the heat insulating material covering the main body portion, a material obtained by solidifying the heat insulating material obtained by mixing asbestos and glass fiber with a molding agent and a material obtained by cutting the heat insulating fiber to match the outer shape of the body are used.

In addition, it is preferable to use a corrosion-resistant material such as stainless steel because there is a high possibility that the body is corroded due to high temperature and generated gas during pyrolysis treatment.

As a result, when the operator operates the pyrolysis apparatus using the food waste and agricultural by-product resources according to the present invention, the raw material is filled into the drying and preheating unit A at an appropriate amount during the initial operation of the pyrolysis apparatus, The apparatus 5 is opened and transferred directly to the pyrolysis processing unit B, and then the rotary opening / closing apparatus 5 is closed and the drying and preheating unit A is filled with a proper amount of raw material. Thus, the pyrolysis of the raw material introduced into the pyrolysis treatment section (B) and the raw material loaded on the drying and preheating section (A) are dried and preheated.

When the food waste and agricultural by-products are introduced through the inlet 2 to start a single process, they are stirred by the stirring device 3 in the drying and preheating part A for a predetermined period of time, Dried and preheated and then opened by the operation of the rotary type opening and closing device 5, (2) the free fall of the pyrolysis treatment part B by its own weight, and the hot air 15 supplied while being stirred by the treatment part agitation device 7 When the pyrolysis is completed, the processing unit is opened again by the operation of the rotary type opening and closing device 9, (3) freely falls down to the cooling and discharging part C by its own weight and then discharged through the discharge port 11, It is finished.

At this time, the start of a new work process is possible even during the preceding process, that is, a process in which the raw material is introduced into the process (1) immediately after the process is completed and the raw material is moved to the process (2).

That is, the respective work processes can be continuously performed for each of the processes including the drying and preheating portion A, the thermal decomposition portion B, and the cooling and discharging portion C.

In addition, the agricultural by-product pyrolysis apparatus using waste heat in the present invention is subject to agricultural byproducts, but it is to be interpreted that the material that can be recycled through food waste or pyrolysis processing is also included in the scope of the present invention .

An experimental example using the agricultural by-product pyrolysis apparatus utilizing the waste heat according to the present invention is shown.

As shown in Table 2, the calorific value of the combustion fuel is about 3333.3 kcal / kg at a water content of about 10%, which is higher than that at 3090.0 kcal / kg without pyrolysis. Experimental results show no ignition and no nitrogen gas at all. If the pyrolysis temperature is lower than 150 ° C and sufficient pyrolysis treatment is performed at 200 ° C or higher, a higher calorific value improvement effect is expected.

The pyrolysis treatment temperature was 150 ℃ and the treatment time was 0.83 ~ 0.92 hours for the food wastes. As shown in Table 3, the lower calorific value of the combustion fuel was about 4016.0 kcal / kg at a water content of about 11%, which was higher than that at 3686.0 kcal / kg without a pyrolysis treatment. Experimental results show no ignition and no nitrogen gas at all. If the pyrolysis temperature is lower than 150 ° C and sufficient pyrolysis treatment is performed at 200 ° C or higher, a higher calorific value improvement effect is expected.
