What are the problems of environmental protection of charcoal machine?

First, we should try to reduce the pollutant emissions from the charcoal machine in the process of producing charcoal.

2. The charcoal products produced by the charcoal machine should meet environmental protection standards. To fulfill these two requirements, you have made corresponding contributions to the cause of national environmental protection.

The charcoal machine does have certain economic benefits. Coupled with the fact that it is winter, it is the peak season for charcoal machines. Pay attention when investing. Raw materials needed to produce charcoal. See if your ingredients are sufficient. Then analyze your local sales, and then choose the appropriate equipment according to your needs. Be absolutely prepared. In short, making money is risky and investing requires caution.

What to pay attention to when investing in charcoal machines?

First, charcoal sales:

Charcoal is a resource product. Its main raw material is sawdust, which is mainly scrap of wood. If the local wood is rich and the price is reasonable, you can set up a factory. The quality of charcoal sales depends mainly on the quality of charcoal. The supply of fine charcoal is in short supply. If the charcoal quality is not good, the sales must be bad, and the general sales radius is within 300 kilometers.

2. Learn to identify the quality of charcoal:

In general, the diameter of the raw material rod is 50mm. After charring, it is reduced to 36-38mm. The charcoal section has metallic luster and feels heavy. If the carbonization does not shrink, one hand is full of black and gray, and there is no gloss, the quality is poor, and the sales price is low.

Three, charcoal machine and technology:

If you go through the investigation, choosing a charcoal machine is a crucial step. The principle and process of the equipment are basically the same. But the production of equipment is quite different. Take the dryer as an example: the raw materials should be dried before making the rod to reduce the moisture content to between 12% and 4%. This requires that the pipe length, pipe diameter, pipe insulation performance, fan volume, wind pressure, and flow rate of the dryer must be suitable for the raw material drying requirements. The dryer should dry raw materials with a moisture content of 35% at one time. Some dryers are not suitable for drying requirements due to the length of the pipeline, wind pressure and air flow. Therefore, the raw materials can be dried 3-4 times, which not only wastes manpower, material resources, electricity, and fuel, greatly increases the cost of carbon production, but also greatly affects the next process-rod production. There are many beginners who cannot properly solve the relationship between drying and making rods. At present, there are many manufacturers selling charcoal equipment. They compete with each other to fight a price war, which greatly affects the product quality. Due to low product prices, some manufacturers cut corners to reduce product performance and product quality, which cannot be guaranteed. Therefore, investors are advised to be cautious and to compare goods to one another.

4. Carbonization technology

Charcoal is a key link in the production of charcoal. There are a variety of carbonization methods, which can basically be divided into two categories: internal combustion method and dry distillation method. Only the carbonization process requirements are different, the carbonization temperature should be 550 degrees-600 degrees is appropriate, early heating should be carried out slowly, earth kiln should be 15 hours is good, machine kiln is 2-3 hours, early heating time is long, can prevent raw materials The stick is wet and cracked. Ensure the quality of carbonization. The quality of charcoal is closely related to the raw rod. Generally, the density of the raw rod should be greater than 1. The simple detection method is: take a section of the raw material rod into the water, the specific gravity of sinking in the water is greater than 1, the specific gravity of floating is less than 1, the density of the specific gravity is higher, and the quality of the produced charcoal is good. After the charcoal comes out of the kiln, it should be ventilated before carbon is released to prevent carbon dioxide poisoning. The charcoal leaving the kiln should be left outside the kiln for more than 8 hours to prevent re-burning of dead ash and fire.
