Description

Environmentally friendly crop straw carbonization device

Technical field:

The utility model relates to a device for carbonizing crop stalks, which belongs to the technical field of plant stalk carbonization.

Background technique:

With the rapid development of the rural planting industry, after the farmers harvest the fruits of the plants, a large amount of plant stalks cannot be disposed of, so they have to burn them in the field, which not only wastes a lot of precious resources, but also pollutes the environment. In recent years, there have been frequent incidents in which planes were unable to take off and land due to straw burning by farmers, and highways were forced to close for several hours due to low visibility. In order to solve this problem, people have also thought of many ways, such as making mechanism charcoal after crushing it, or making it into plant fiber high-density board, or directly using it as boiler fuel. Although these methods can solve certain problems, but because of There are too many straws, loose and messy, and it is inconvenient to transport and store. In addition, these methods have certain requirements on the quality of straws. Therefore, a large amount of straws are still unused and burned. There is also the method of crushing the stalks on the spot and returning them to the field, but the stalks need 2-3 years to decompose in the field, which will cause great damage to the soil quality in the field, and also affect the planting of crops. The best way now is to carbonize plant straws as a renewable energy source instead of coal, but most of the existing carbonization furnaces have complex structures, and the straw needs to be crushed before carbonization can be carried out, and a large amount of carbonization is produced during the carbonization process Harmful gases are still discharged into the atmosphere through chimneys, causing secondary pollution.

Invention content:

The purpose of this utility model is to provide an environment-friendly crop straw that overcomes the shortcomings of the existing straw carbonization furnace. When carbonizing, the straw does not need to be crushed or processed, and can be directly stacked and then carbonized. It is simple in structure, safe and reliable, and easy to operate. Carbonization device.

The utility model realizes above-mentioned purpose through following technical scheme:

A smoke collecting device is installed on the outlet of the wet path, the flue exhaust path and the wet exhaust path, and the other end of the smoke collecting device is connected to the smoke elimination pool. Both sides of the bottom of the kiln body are provided with a left air inlet and a right air inlet connected with the left air inlet pipe and the right air inlet pipe. The kiln door has a fire port and a fire viewing port. The inner wall of the kiln body is provided with an insulating layer. A smoke exhauster is installed on the smoke collecting device.

Compared with the prior art, the utility model has the following advantages:

1. The carbonized straw raw material of the utility model does not need to be crushed, and can be dry, wet or raw.

2. The utility model can be made of metal, also can be made of bricks, and can also be made of yellow mud dry base with good texture, and the making materials are easy to get.

3. The utility model separates the wet discharge channel, the smoke exhaust channel and the air intake channel, and connects and circulates through the space in the kiln, so that the carbonization process is very thorough, and the quality of the carbonized products produced by carbonization is good.

4. The utility model can be directly built in the raw material base, and the raw materials are obtained locally, which reduces the manpower and transport capacity for straw collection, transportation and processing, reduces costs and expenses, and is easy to popularize and apply in rural areas.

Detailed ways:

The environmentally friendly crop straw carbonization device consists of a kiln body 1 , an ignition device 3 , a wet exhaust duct 5 , a flue exhaust duct 6 , a left air inlet pipe 14 , a right air inlet pipe 15 , a smoke collection device 7 and a smoke elimination pool 9 . There is a kiln door 13 on the kiln body 1, an ignition device 3 is formed in the middle of the kiln body 1, and a partition screen is placed on the ignition device 3, and a flue exhaust duct 6 and a wet exhaust duct 5 are formed on the rear side of the kiln body 1. A smoke collecting device 7 is installed on the outlet of the flue 6 and the wet discharge channel 5 , and the other end of the smoke collecting device 7 is connected to the smoke elimination pool 9 . The bottom both sides of kiln body 1 are shaped on left air inlet pipe 14 and right air inlet pipe 15, and left air inlet pipe 14 is connected with left air inlet 2, and right air inlet pipe 15 is connected with right air inlet 10. Have a fire port 4 and a fire viewing port 11 on the kiln door 13. The inner wall of the kiln body 1 is provided with an insulating layer 12 . The smoke collecting device 7 is equipped with an ignition smoke exhauster 8 , and the end of the smoke collecting device 7 communicates with the smoke elimination pool 9 . The kiln body 1 is made of bricks, and can also be made of yellow mud. The inside of the kiln body 1 is adhered with an insulating layer 12 made of earth, and the small kiln body 1 can also be made of metal.

Before carbonization, open the kiln door 13, put the dry materials such as soybean stalks and cotton stalks on the partition net of the ignition device 3 in the kiln body 1, and then divide the left and right sides into flat piles of straw or trees to be carbonized The branches and leaves should be piled up and pressed down. The tighter and firmer the better, the fuller the better. After installation, seal the kiln door 13, open the left air inlet 2 and the right air inlet 10 and the wet discharge channel 5, close the fire viewing port 11 and the flue exhaust channel 6, and then send the kindling from the ignition port 4 to ignite the inside of the kiln body 1 The flammable kindling on the ignition device 3. After seeing the smoke from the wet discharge channel 5, confirm that the charcoal is ignited, then close the ignition port 4, then gradually close the left air inlet 2 and the right air inlet 10, open the fire viewing port 11, and observe the flame burning in the kiln body 1. When the kiln body 1 After all fires inside, close the fire viewing port 11 immediately. After the temperature in the kiln body 1 is uniform and the charcoal burns normally, then close the wet exhaust duct 5, open the flue exhaust duct 6, and pay attention to observe the flue opening. There is clear smoke and a little spark from the flue opening, indicating that all the items in the kiln are being carbonized middle. One hour later, spray mist high-pressure water from the fire viewing port 11 to extinguish the fire, and then close the fire viewing port 11 to fill the kiln with water vapor, so that the water vapor enters the carbonized product, and the carbonized product is filled with negative oxygen to enhance the hardness of the carbonized product Spend.

About half an hour later, when the temperature in the carbonization device drops, check whether there is an open flame in the kiln body 1 from the fire viewing port 11. If there is an open fire, use tap water to extinguish the fire. If there is no large open fire, just a small light, then The kiln door 13 can be opened, and the charcoal is discharged from the kiln. If a fire is found in the charcoal during the charcoal discharge, it can be eliminated with water immediately. The items taken out of the carbonization device are the finished carbonized products.

The utility model is equipped with a smoke collection device 7 and a smoke exhauster 8 on the outlet of the exhaust duct 6. The smoke exhauster 8 can make the straw in the kiln body 1 carbonized more thoroughly. 9 is connected, so that the harmful gas produced in the carbonization process, under the action of the ignition smoke exhauster 8, enters the smoke elimination pool 9 through the outlet of the smoke collection device 7 and then settles to dissolve tar and nicotine, so that the device can be used in the carbonization process. No secondary pollution will be generated.
