Description

Technical Field

[0001] The present invention relates to the technical field of carbonizing diseased wood, in particular to equipment for carbonizing diseased wood. Background Art

[0002] The pine wood nematode (Bursaphelenchus xylophilus) disease is a major plant disease that was introduced to my country in 1982. It has killed over 70 million pine trees and now threatens the safety of over 600 million mu (approximately 1667 acres) of pine forests. Pine wood nematodes are highly reproductive and rapidly decimate trees, killing pine trees within 40 days of infection and causing deforestation within 3-5 years. By the end of 2020, the disease had affected 18 provinces, autonomous regions, and municipalities, encompassing 726 counties, covering an area of ​​1.8092 million hectares and killing 19.4703 million pine trees. The diseased areas in provinces (and municipalities) such as Jiangxi, Guangdong, Zhejiang, Fujian, Anhui, and Chongqing exceeded 600 hectares. The development of pine wood nematode control technologies is urgent.

[0003] The technology of treating diseased wood and making high-value use of it is the key to controlling the spread of pine wood nematode disease and turning diseased wood into treasure. At present, the main methods of treating diseased wood are on-site burning and fumigation. Although this treatment method can effectively prevent the loss, hiding, smuggling, and incomplete pest control of diseased wood after it is brought down from the mountain, it is easy to cause forest fires and waste wood resources. Fumigation treatment has strong regional limitations and cannot fundamentally kill pine wood nematodes, which is not conducive to large-scale promotion. my country's forestry industry urgently needs key technologies and equipment for the treatment and high-value use of diseased wood. As early as the 1980s, the Forest Research Institute of the Ministry of Agriculture, Forestry and Fisheries of Japan launched the BA-1 mobile carbonization furnace. Canadian researchers have proposed a vehicle-mounted pyrolysis unit with an internal circulating bed. This unit separates the pyrolysis and combustion zones within the same reactor chamber. The combustion zone serves as the inner layer, while the pyrolysis zone serves as the outer layer. The pyrolysis zone is equipped with a lifting guide pipe that penetrates the combustion zone bed. Propelled by the fluidizing gas, the pyrolysis bed material and biomass feedstock are continuously transported along the lifting pipe through the combustion zone, where they gain heat and achieve biomass pyrolysis. Another researcher has proposed a compact dual-bed vehicle-mounted pyrolysis unit. A screw at the bottom of the dual fluidized beds exchanges bed material between the two beds, pushing biochar produced in the pyrolysis zone into the combustion zone for combustion. Bed material circulation then returns heat to the pyrolysis zone to maintain the pyrolysis reaction. This dual-bed mobile pyrolysis unit achieves autothermal operation, but the reactor is relatively large and requires nitrogen reserves for purging and blowing. In the 1990s, small-scale carbonization furnaces were used across China to carbonize agricultural and forestry waste. Combustible gases accounted for approximately 60% of the collected gases, with a charcoal yield as high as 40%. This indicates that woody plants have a higher fixed carbon content than herbaceous plants after carbonization. Other researchers have also applied mobile carbonization furnaces to forestry operations, producing charcoal that meets international standards. In recent years, small-scale continuous-feed straw carbonization devices have been developed to recover and utilize the combustible gases generated during thermal degradation.

[0004] In summary, the current technology for treating and utilizing diseased wood is not yet mature, and the main difficulties are as follows: it is impossible to kill pine wood nematodes at the source, diseased wood resources cannot be effectively utilized, and secondary pollution is caused during the treatment process.

[0034] In this specific embodiment, a track 17 that cooperates with the bottom of the aggregate frame 202 is laid on the bottom plate of the biomass pyrolysis chamber 201, the top of the water tank 301 and the top of the water collection pool 302. A guide rod 18 is provided on the top of the track 17, and a sleeve 19 is provided at the tail end of the aggregate hole facing the water collection pool 302.

[0035] In this specific embodiment, the top of the side sealing door 204 is hinged to the biomass pyrolysis chamber 201, and a winch 23 is provided on the turbulence tower 402 on one side of the water tank 301. A pulley 24 and a fixed ring are provided at the bottom of the side sealing door 204.

The left turbulence tower 402 is equipped with three-stage blades to increase air flow rate. After being accelerated by the three-stage blades, the flue gas reaches the pellet adsorption area within the right turbulence tower 402. To improve dust removal efficiency, both the left and right turbulence towers 402 are equipped with spray ports connected to the bottom water tank 301. This not only reduces the flue gas temperature and prolongs the life of the pellets, but also increases dust reduction efficiency. A water pump circulates the water source within the water tank 301 of the turbulence tower 402.

[0038] The process of the pest-wood carbonization equipment of the present invention is as follows:

[0039] (1) Open the top sealing door 203 and hoist the materials into the biomass pyrolysis chamber 201.

[0040] (2) Before the equipment is put into operation, check all components, close butterfly valve five 13, butterfly valve three 11, butterfly valve one 9, open butterfly valve four 12, butterfly valve two 10, fill the water tank 301, and then start pump one to inject the water source in the water tank 301 into the turbulent tower 402 water tank 301, and rotate the pressing device 26 to press the side sealing door 204 to ensure the airtightness of the carbonization chamber.

[0041] (3) For the first time, fill the combustion chamber with fuel to one-quarter of the maximum load and discharge it concentratedly at the grate position. Do not add too much fuel to cause smoldering.

[0042] (4) Adjust the induced draft fan to 20Hz, open the ash cleaning chamber 30, and use a flamethrower to ignite the materials in the combustion chamber. The ignition time is 15-30 minutes.

[0043] (5) After the materials are ignited, the biomass combustion chamber 101 and the ash cleaning chamber 30 are quickly closed, and the frequency of the blower 16 is slowly adjusted to 20 Hz. After the equipment is running stably, the frequencies of the induced draft fan and the blower 16 are uniformly adjusted to 30 Hz.

[0044] (6) After 30-45 minutes of stable operation, fuel is loaded for the second time to the maximum load of the combustion chamber. After loading, the biomass combustion chamber 101 is sealed and the blower 16 is restarted to keep the Hz number unchanged.

[0045] (7) After 60 minutes of operation, observe the reading of the turbulence tower 402 thermometer. If it exceeds 70°C, start the water pump through the control box to replace the water source inside the turbulence tower 402 to prevent the plastic pellets from burning due to excessive flue gas temperature. Thereafter, observe the reading of the turbulence tower 402 thermometer every 60 minutes. If it exceeds 70°C, start the water pump to replace the water source in time.

[0046] (8) After 90 minutes of operation, the blower 16 is turned off and the fuel is loaded for the third time, filling the combustion chamber to the half load position.

[0047] (9) After 120 minutes of operation, the fuel in the combustion chamber is basically burned out, and the butterfly valve three 11 and butterfly valve five 13 are opened, and the butterfly valve four 12 and butterfly valve two 10 are closed, and the pyrolysis gas is passed into the combustion chamber through the Y-type burner.

[0048] (10) If the product demand is biochar, wait until the pyrolysis gas is burned out and taken out of the furnace. After taking out of the furnace, start water pump 1 303, close water pump 2 304, open the spiral nozzle and continue to run.

[0049] (11) Rotate the pressing device 26, open the side sealing door 204, move the aggregate frame 202 to the cooling chamber, and after reaching the designated position, close the side sealing door 204 and press it.

[0050] (12) Open the top sealing door 203 and hoist the new material into the carbonization chamber for the next round of operation.
