Description

Fire pan type gasification carbonization furnace
Technical Field
The invention belongs to the technical field of biomass comprehensive utilization equipment, and particularly relates to a fire pan type gasification carbonization furnace.
Background
At present, the technology of returning crop straws to the field is popularized, but the problems of plant diseases and insect pests and seeding quality caused by returning the crop straws to the field are not well solved, and the straw biomass is degraded into carbon dioxide gas by microorganisms in a short time after returning the crop straws to the field, so that the carbon fixation effect is low, and the contribution to soil organic matters is limited. So although the government prohibits burning the straws, the government still prohibits burning the straws. The biochar has the advantages of attractive potential of improving soil, reducing emission and increasing sink because of the special porous structure and the ultra-long carbon sealing property, so that the biochar technology can replace a straw returning technology. However, the biochar technology is not applied in a large scale until now, and the reason is that the existing gasification carbonization equipment is large in design scale and large in transportation radius of raw materials, and wastes such as crop straws belong to low-value materials which are difficult to transport, so that the transportation cost and the pretreatment cost are high, the benefit is low, and the popularization is difficult.
Disclosure of Invention
The invention aims to solve the technical problems of complex structure, long transportation distance of raw materials such as crop straws and the like and high cost of the conventional biomass carbonization treatment equipment, and provides a fire pan type gasification carbonization furnace.
In order to solve the technical problems, the invention adopts the technical scheme that:
the utility model provides a fire pan formula gasification retort, includes the furnace body, protects along, a plurality of adjusting bolt, furnace mantle and chimney, the furnace body is the tapered barrel of upper coarse and lower thin, and does not have top surface and bottom surface, the furnace mantle is the tapered barrel of upper fine and lower thick, and its bottom edge is equipped with protects the edge, the top edge of furnace body evenly sets up a plurality of adjusting bolt, the furnace mantle is put on the adjusting bolt that the furnace body top set up and is made to protect along the top of covering the furnace body, the chimney is established on the nozzle on furnace mantle top, the well lower part of chimney evenly is equipped with a plurality of fresh air inlet.
Furthermore, an ignition port is arranged on the conical surface of the furnace cover.
Furthermore, the diameter of the bottom end of the furnace cover is larger than that of the top end of the furnace body.
Further, the number of the adjusting bolts is greater than or equal to 3.
Compared with the prior art, the invention has the beneficial effects that:
1. in the combustion process of biomass materials in the device, air can enter the furnace body from the first air inlet channel, the second air inlet channel and the third air inlet channel so as to provide the oxygen demand in the biomass thermal cracking process and the pyrolysis gas combustion process, and the aims of efficiently producing biomass charcoal and fully combusting pyrolysis gas are fulfilled;
2. the device has simple structure and convenient operation, can directly and quickly carry out carbonization treatment on biomass wastes such as straws and the like in the field, and the produced biomass charcoal can be directly applied to the field and can also be mixed with organic fertilizer or chemical fertilizer for use, thereby reducing production and application links, lowering cost, improving production efficiency and being convenient for popularization and application.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1-furnace body, 2-ignition port, 3-protective edge, 4-adjusting bolt, 5-furnace cover, 6-chimney and 7-air inlet.
Detailed Description
The invention is further illustrated by the following figures and examples.
As shown in fig. 1, a fire pan type gasification carbonization furnace, including furnace body 1, guard edge 3, 3 adjusting bolt 4, furnace mantle 5 and chimney 6, furnace body 1 is the thick tapered barrel body down, and does not have top surface and bottom surface, furnace mantle 5 is the thick tapered barrel body down, be equipped with ignition mouth 2 on the conical surface of furnace mantle 5, its bottom edge is equipped with guard edge 3, the top edge of furnace body 1 evenly sets up 3 adjusting bolt 4, furnace mantle 5 is put on adjusting bolt 4 that furnace body 1 top set up and is made guard edge 3 cover the top of furnace body 1, and the diameter of its bottom is greater than the diameter on furnace body 1 top, chimney 6 is established on the smoke vent on furnace mantle 5 top, the well lower part of chimney 6 evenly is equipped with a plurality of fresh air inlet 7.
The number of adjusting bolts 4 can also be any number greater than 3.
The working principle of the invention is as follows:
when crop straws or fruit tree branches and the like need carbonization treatment, the device is conveyed to the field, padding materials such as bricks and the like are placed at a proper position according to the size of the bottom of the furnace body 1, then the bottom of the furnace body 1 of the device is placed on the placed padding materials, the furnace body is stable, gaps among the padding materials are first air inlet channels, biomass materials to be treated are added into the furnace body 1, the furnace cover 5 is covered on the top of the furnace body 1, a second air inlet channel is formed among the furnace body 1, the furnace cover 5 and the protective edge 3, the distance between the furnace cover 5 and the furnace body 1 is adjusted through the adjusting bolt 4, the air inlet amount of the second air inlet channel can be controlled, the chimney 6 is installed on the top of the furnace cover 5, and the air inlet holes 7 on the chimney 6 form a third air inlet channel.
The biomass material is ignited from the ignition port 2, the biomass material starts to burn from top to bottom, and in the burning process, air enters the furnace from the first air inlet channel, the second air inlet channel and the third air inlet channel so as to provide the oxygen demand of the biomass material cracking process and the pyrolysis gas burning process, and the biomass is quickly carbonized and the pyrolysis gas is fully burnt. And after the cracking is completed, taking down the furnace cover 5, burying the biomass charcoal with soil or pouring water to kill the biomass charcoal, and then carrying out the next furnace operation.
The furnace type thermal cracking has large reaction surface, high working efficiency and biochar yield of about 25 percent, and achieves the purposes of fully burning the cracking gas and realizing the standard emission of tail gas. In addition, the furnace type is simple in structure and convenient to operate, can be suitable for field rapid carbonization treatment of crop straws, fruit tree branches and the like, saves high cost caused by transportation of wastes such as the crop straws and the like, and can be directly used in the field to avoid working procedures such as collection and transportation of biochar.
