Carbonization standards and specifications in carbonization equipment
How do you determine the stage of carbonization temperature separately? Under the low-temperature carbonization process, the materials in the chassis will be released continuously with the increase of temperature, and the speed is relatively fast. In the carbonization process, a large amount of air volume is generated, and the capacity entered in the container is more, which will result in Many large and small holes.
Under the action of these holes, the adsorption will increase with the change of temperature, and the operation speed of the carbonization process technology in the charcoal briquette machine will also accelerate, and the efficiency will become high. The cost is relatively low and its application is strong. After a long time of operation, the charcoal briquette machine equipment will suffer a certain degree of damage to the shaft head. If it is not repaired in time, it will affect the normal operation of the equipment. After the experimental research, the technicians will share their repair methods. The following is a detailed introduction:
1. According to the welding process in front of thecharcoal briquette machine equipment, after being preheated, it is evenly used for the surfacing of J422 carbon-bonded electrode on the outer surface of 105mm long, which exceeds the measured outer circle size of 1~2mm, leaving the remaining A good amount of sanding correction.
2. After the initial grinding correction, insert the shaft head of the charcoal briquette machine into the dried quicklime or plant ash, cool it to below 50 C for complete grinding, and grind it to a circular runout of no more than 2 mm, and the circumferential surface has no obvious wet and convex Just fine. After the repair of the shaft head of the charcoal briquette machine, it is strictly forbidden to knock or collide, so as to avoid damage to other parts of the surfacing area, and should be carefully stored for use.
According to the equipment used for carbonization, it is also the most important. The carbonization furnace must be tightly sealed. Once there is air leakage, the amount of oxygen entering the furnace (or kiln) cannot be controlled. The salary bar in the furnace is easy to auto-ignite excessively so that the carbonization temperature rises too fast so that the charcoal produced is loose and easily broken. What's more, excessive oxygen will burn some of the salary bars into a white powder (ash), which will reduce carbon production and increase the cost of the finished carbon.
Carbonization is an important part of charcoal. The carbonization process is the core of charcoal production technology. Just like building a building. Good raw materials are the foundation of the building. The carbonization process in the carbonization process is the above-ground part of the building. The carbonization is divided into three stages: low-temperature discharge temperature, high-temperature calcination, and cooling and cooling. The salary bar has about 8% water when it enters the carbonization furnace. This water is the enemy of carbonization.
Because the salary bar is most afraid of getting wet, the water will seriously affect the quality of carbonization in the salary bar. Because the time of the tide is essential. Tidal time is essential. The tidal time is generally 10-15 hours for the earthen kiln and 2-3.5 hours for the charcoal kiln. The long heating time can prevent the salary bar from being cracked by moisture and ensure the quality of carbonization. When the furnace temperature rises to 300 degrees, a large amount of combustible gas can be generated in the furnace.
Each kilogram of raw material is logically equivalent to produce three cubic methane gas. These gases can be used to heat the furnace. The exhaust heat source for drying more than 400 degrees for the heat preservation calcination stage to seal the oxygen-free closed fire can be taken from spontaneous combustion or water cooling. After the charcoal is discharged from the kiln, it must be ventilated and then charcoal to prevent carbon dioxide poisoning. The charcoal from the kiln should be placed outdoors for more than 8 hours. Prevent resurgence and fire.
