Description

Chaff carbonization device {Carbonized rice-hulls burner}

The present invention relates to a chaff carbonization device in which the production of Huntan is produced by the self-heating of the rice husk, in detail, the low oxygen after the initial ignition by collecting and discharging the steam and gas generated during the carbonization process into the flue gas formed through the inside of the chaff layer The present invention relates to a chaff carbonization device which obtains rice husk carbide in high yield by allowing carbonization under conditions, and produces rice husk coal by self-burning without consuming external energy.

Chaff is a by-product that contains about 18% of the weight of rice and is produced abundantly every year.It is mainly used for livestock rugs for composting, for some culvert drainage, seedling badges, farmland rugs, steel insulation materials, siliceous reinforcement of concrete, and fuel. SiO _{2 used} As it is more than 92% of ingredients, it is difficult to be used as a compost or seedling medium, and there is a limit, and since it is ignited at a high temperature of 300 ℃ or higher, there is a limit to use as a fuel. have.

On the other hand, rice hull coal produced by carbonization process by incomplete combustion is produced in yield of 40-50% which is more than twice as much as sawdust hultan, sterilization in carbonization process, strong moisturizing effect, voids and drainage and It has excellent ability to improve the physical properties of the soil, so it can be used as a clay material that can replace expensive imported soil.The carbonization process decomposes substances that hinder combustion performance and improves combustibility. There is an advantage that can be utilized as fuel.

For this reason, various efforts have been made to produce rice hulls from Huntan beyond simple use as livestock litter.

According to the results of the previous research, the chaff is endothermic under oxygen or anoxic conditions up to approximately 280 ℃ and then burned by exothermic heat when it is continuously heated at 320 ℃ or higher. It is made, and thermal decomposition by exothermic reaction is continued to about 440 ° C., so that the molecular bonds of polymer materials such as cellulose are broken down and oxidatively decomposed, and around 600 ° C., there is a combustion characteristic in which carbon component is hardly left but ash remains.

In addition, the chaff has a weight loss of about 8 to 10% as the primary chaff is discharged by endothermic pyrolysis up to 280 ° C and pyrolysis by exotherm above 320 ° C, resulting in low molecular volatility at 320 ° C. The organic material is volatilized to reduce the weight by 40 to 50%, the molecular structure of the polymer material is destroyed at 440 ° C, and the weight is reduced by 10 to 20%. In addition, volatile organics, which are carbonaceous materials produced during pyrolysis, increase in proportion to the reduction of carbonaceous materials due to pyrolysis. As such, approximately 35% of the carbonaceous materials generated by pyrolysis are condensed wood vinegar and tar, and these materials adhere to the fuel supply passage and constrict in the combustion process.

Due to these characteristics, the method of preparing the charcoal by using the rice husk in the carbonization tank and heating the carbonization tank to discharge the steam and condensable material together to make the carbonization is performed. Although it is suitable, it is difficult to mass-produce, and it is low productivity because it is batch-input-heat-exhausted in stages, and the charcoal of charcoal is made under air condition. Falling, there is a high risk of fire, there is a problem that the production cost is high because the energy consumption for carbonization must be made continuously.

The Republic of Korea Utility Model Publication No. 20-0148825 forms an upper hopper and softener on the upper part of the tank, and forms an ignition heater, a blower, and a damper on the lower part of the tank, and injects the rice husk into the tank. After the rice husk is put in, open the damper to supply blown air, start the ignition heater to ignite the rice chaff to carbonize the rice husk, and collect the wood vinegar that has flowed into the upper hopper. It suggests the rice hull huntan manufacturing apparatus of the structure that discharges hulhutan.

The structure is a structure that produces hultan and wood vinegar by the combustion of the chaff itself after the initial ignition by the ignition heater may be applied to the small-sized coal-fired manufacturing apparatus, but the chaff is burned by the forced air supply there is a fear of fire caused by overheating The yield is very high, the combustion is performed by the heat of rice husk over 480 ℃, the yield of Huntan falls below 50%, the wood vinegar component containing tar narrows the year, and the process of discharging the final Huntan from the first input of rice husk has a long productivity. Low, there is a problem that is very difficult to control the amount of air supply to increase the yield of Huntan.

Chaff Huntan indirect heating continuous automatic manufacturing device according to the patent registration No. 0316359 carbonizes the rice husk into the continuous carbon tube heated by the burner heating device, carbonizes the rice husk, and recovers the combustible gas generated during the carbonization process of the rice husk It is used as gas, and the tar removal part by hydraulic cylinder is installed in order to prevent the constriction of refrigerant gas by tar, and the structure including the fume carbonization part using liquid nitrogen makes the input and discharge of rice hull and the extinguishing of charcoal It suggests the rice hull bullets indirect heating continuous automatic manufacturing device.

The structure has no countermeasure against rapid narrowing of the carbonization tube by tar, and the volatile combustible gas recovered during the carbonization can replace a part of the energy required for carbonization, but it is not sufficient, and nitrogen gas for extinguishing continuously Due to the large size of the auxiliary equipment and excessive maintenance costs, the production cost of Huntan was high, and high safety management such as fire prevention was required.

The direct fired rice husk-coal continuous production apparatus according to Korean Patent Registration No. 0316360 is formed with an injection chute having an input opening / closing damper at the upper side of the heating unit and a hopper-shaped combustion chamber body formed with a pressure gauge, and is provided at the upper side of the discharge port inside the combustion chamber body. Combustion air supply nozzle and combustor are formed. Combustion of chaff in the combustion chamber while air is supplied to the combustor, and combustible gas generated in the combustion process extracts the combustible gas and re-injects it into the combustion chamber body, thereby making it possible to perform the coal-fire process without inputting external fuel. Continuously carried out, the bottom discharged huntan is composed of a structure that is extinguished by the chuntan cooling unit by nitrogen gas and double water jacket.

The structure is a structure that produces charcoal, hultan, by the self-burning of rice hulls, and the tar generated during the combustion process has to stop frequently and remove the tar layer due to the rapid narrowing in the combustion chamber body, the intake pipe and the cyclone. There is a problem, and the nitrogen gas for extinguishing is continuously consumed, and the size of the auxiliary equipment is large, so that the maintenance cost is excessively consumed, the production cost of hultan is high, and high safety management such as fire prevention by controlling combustion air There was a problem required.

The chaff charcoal manufacturing apparatus according to Patent Registration No. 10-0553383 proposes the chaff charcoal manufacturing apparatus having a structure of reducing the combustion time and the digestion time by forming a plurality of small hutantan tanks, but the structure of the Huntan process under the air supply state. As a result, the precise control of the air supply influences the yield of Huntan, the high risk of fire due to overheating, and the narrowing of the communication part by tar is pointed out as a problem.

The combustion layer is not overheated and the heat of 300 ℃ ~ 400 ℃, which is the optimal temperature for chaff carbonization, is continuously maintained, and the chaff huntan that has not reached complete combustion is extinguished in the process of being pushed down while maintaining the shape of the chaff. It is fired and then discharged by the Huntan exhaust system to provide the effect of continuous production of rice hulls.

In addition, inside the chaff carbonization chamber, the optimum temperature for carbonization of chaff is continuously maintained at 300 ° C to 400 ° C, and the chaff belonging to the combustion layer is carbonized by combustion and immediately extinguished by insufficient air, resulting in high yield of chaff It can be manufactured and there is no need to use a separate fire extinguishing system in the process.

The present invention proposes together the chaff carbonization device which is made in the input of the chaff and the discharge of the huntan in the above configuration to improve the efficiency of the production of huntan.

To this end, the present invention has a chaff supply device for continuously supplying chaff to the chaff carbonization chamber (50), and the Huntan discharge device 60 for continuously discharging the rice husk coal generated in the chaff carbonization chamber Is installed.

The rice hull supply device 50 may be configured in a batch type as a device for injecting rice husk, and may be configured in a continuous manner.

In the case of the batch type, the chaff supply device 50 is chaff by a transfer device such as a screw through a chaff inlet 11 formed at the top or side wall of the rice hull carbonization chamber or an openable cover 12 formed at the top of the rice husk carbonization chamber. It can be configured to inject or chaff by manpower.

When the chaff supply device 50 is continuously configured, as shown in FIG. 2, a transfer screw 51 having a spring structure extending to an upper portion of the rice husk carbonization chamber 10 is installed to the outer hopper 52. The rice hulls can be stored continuously.

It may be configured to a structure that is discharged after purification through the gas purifier (90).

The above structure can separate high-purity wood vinegar from carbonization gas discharged from flue gas, purify and discharge air pollutant generated during incomplete combustion process, and extract and utilize flammable gaseous material as needed. Will be.

The operation of the chaff carbonization apparatus according to the present invention can be described as follows.

Fill the chaff to approximately 2/3 the height of the chaff carbonization chamber 10 using the chaff supply device (50).

Next, the firebox opening 23 which comprises the initial ignition apparatus 20 is opened, and the rice husk which contacts the firebox 21 is burned using a burner (or a firewood) in the state which air supply is performed.

In the state in which the fire chamber opening 23 is opened, the air necessary for combustion is supplied into the fire chamber 21, and the heat generated by the ignition device acts on the rice husk, so that the rice husk is subjected to the normal endothermic step and the exothermic step, and is approximately 320 ° C. or more. Ignition at temperature leads to combustion.

At this time, the water vapor and carbonized gas material generated during the initial ignition process are collected through the through-holes of the flue gas cylinder 30 arranged uniformly and discharged to the outside of the rice husk carbonization chamber by the chimney effect, and does not supply the separate combustion air by the discharge pressure. Even if it is not necessary, sufficient air for initial ignition is supplied to the combustion layer F inside the rice husk carbonization chamber through the open flame chamber opening 23.

The temperature raised by the ignition of the rice hull heats the surrounding rice husk, and the heat-absorbed rice husk evaporates the water vapor inside the primary to be discharged through the flue gas pipe. Carbonization takes place, and the gaseous substances generated during the carbonization process are discharged through the flue gas secondaryly, and combustion is diffused to increase the temperature in the rice husk carbonization chamber.

The elevated temperature in the rice husk carbonization promotes the burning of the rice husk, and the combustion layer is diffused to ensure the exothermic reaction of the rice husk itself and the amount of heat required for combustion.

If the chaff itself burns out, remove the burner or stop the firewood supply and close the firebox opening. If the initial ignition device is composed of heating elements, the operation of heating elements is stopped, and the air supply is closed to cut off the air supply from the bottom.

When the fire chamber opening 23 or the air supply port is closed, the lower portion of the rice husk carbonization chamber 10 is kept in a closed state so that air from the lower portion is blocked, and no more vigorous combustion occurs, and the air existing between the rice husks Incomplete combustion is caused by the air supplied from the top of the rice husk carbonization chamber.

That is, when water vapor and carbonized gaseous substances are discharged to the flue gas cylinder 30 through the through-hole 31, a negative pressure is formed in the layer (combustion layer) where combustion occurs in the chaff carbonization chamber by the chimney effect. Air is absorbed through the chaff surface layer on top of the open chaff carbonation chamber and used for combustion.

Air absorbed through the chaff surface layer is absorbed by the negative pressure formed by the discharge of the gaseous material formed by the combustion has the following combustion characteristics.

First, it is always inadequately supplied than the air necessary for burning chaff.

Therefore, the decomposition is stopped at the initial stage of combustion without undergoing the weight loss process due to endothermic heat decomposition, the carbon decomposition process and the final ash generation process, and the heat formed by the combustion is the chain of neighboring rice husks. Combustion of the chaff is carried out, and the air provided by the burning of the rice husk is extinguished, and at the same time, the combustion is stopped to produce a high yield of incomplete combustion material of the rice husk.

In addition, the discharge of the carbonization gas material and the intake of the outside air is somewhat balanced, so that a constant temperature is always maintained in the chaff carbonization chamber, and an overheating state does not occur.

Second, the chaff of the chaff (F) has a characteristic that always moves upward.

The combustion of the rice hulls in the rice husk carbonization chamber is maintained when a temperature of 320 ° C. or more is maintained for a certain time, and a combustion layer is formed when the conditions for supplying air for combustion are satisfied.

The combustion layer is initially formed in the initial ignition part because the air supply from the lower part is blocked while the combustion is performed by ignition by the air supplied from the lower part of the first rice husk carbonization chamber.

The air maintaining the combustion layer is introduced from the upper layer by the chimney effect, and the lower layer is blocked in the air supply in a sealed state, so that the lower portion F2 of the combustion layer is not supplied with air but only the upper air is supplied. Gradually rises.

Carbonized rice husk coal in the lower layer can be easily burned by the decomposition of silicic acid, which is a combustion disturbance, by pyrolysis, but it is initially burned due to no air supply and is extinguished after carbonization. The heat generated is used for the combustion of the upper chaff, and the heat is deprived of itself, allowing it to cool down over time without additional extinguishing and to be continuously discharged by the Huntan exhaust system.

Third, by adjusting the chaff input amount to the combustion rate, the combustion layer in the rice husk carbonization chamber can be maintained at a constant height.

Combustion of the rice husk proceeds upward, the lower part of the combustion layer is extinguished, and the upper layer is combusted, and if there is no additional supply of rice hull, the combustion layer gradually rises, and in the final stage, the combustion is terminated, leaving only the rice husk charcoal in the rice husk carbonization chamber. Therefore, the batch rice husk carbonization device can be easily configured.

In addition, if the chaff is continuously added while the combustion layer is maintained, and the Huntan generated from the lower part is continuously discharged, the chaff combustion layer is maintained inside the chaff carbonization chamber. Since the combustion layer can be kept constant in the carbonization chamber, it is possible to easily configure a continuous chaff carbonization device.
