Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the utility model discloses furnace inner structure of low temperature degradation stove, including support 1, furnace body 2, go out tobacco pipe 3, put in mouth 4, ash pipe 5, energy conversion device 6, furnace body 2 is fixed subaerial through support 1, furnace body 2's upper end center is equipped with the play tobacco pipe 3 that communicates its stove inner upper portion, upper portion one side of furnace body 2 is equipped with puts in mouth 4, furnace body 2's lower extreme center is equipped with ash pipe 5, still be fixed with the energy conversion device 6 who produces the magnetization wind on the support 1, the export of energy conversion device 6 communicates middle part in the furnace body 2 and lets in the magnetization wind to its inside.
The working process is as follows:
domestic waste drops into furnace body 2 from rubbish input port 4 and carries out low temperature degradation, because energy conversion device 6 supplies the magnetized air to the furnace middle part through magnetized air distribution ring pipe 8, consequently degradation stove inner space is divided into three region: the drying area A, the carbonization area B and the degradation area C, the middle part directly contacts the magnetized air as the carbonization area, the magnetized air carries heat upwards to dry the garbage just thrown into the upper part, the carbonized materials are continuously degraded at the lower part, and finally, dry hot ash is formed and discharged from an ash outlet 15 at the lower part for collection and treatment.
The outer wall of the furnace body 2 is coated with the heat preservation layer 7, the heat in the furnace body is diffused and slowed down due to the heat preservation layer 7, and the heat generated by degradation can be used for garbage self reaction, so that the heat energy required by the thermal degradation of the whole system is greatly reduced, and the energy loss is saved.
The middle part of the outer wall of the furnace body 2 is fixed with a magnetized air distribution ring pipe 8, the magnetized air distribution ring pipe 8 is communicated with an outlet of the energy conversion device 6, a plurality of outlet pipes which are led into the interior of the furnace body 2 are uniformly arranged on the magnetized air distribution ring pipe 8, and the magnetized air distribution ring pipe 8 enables the magnetized air in the carbonization area B to be more uniform, thereby being beneficial to the high-efficiency and high-quality completion of carbonization and drying in the furnace.
Be fixed with motor 9 under ash pipe 5, the vertical upwards and fixedly connected with (mixing) shaft 10 of output shaft of motor 9, the middle part in (mixing) shaft 10 upper end extends furnace body 2, evenly be equipped with a plurality of stirring leaves 11 on the (mixing) shaft 10, in use, motor 9 is not continuous rotation, but timing work, it rotates once at a certain time of establishing through software setting control, rotate certain number of turns at every turn, the primary function is to make the magnetized breeze have certain circulation in carbonization district B, accelerate the carbonization speed. The lower extreme of (mixing) shaft 10 is fixed with the upper portion that covers protection casing 12 and protection casing including motor 9 cage for the conical surface, and protection casing 12 can not influence motor 9 when making the dry-heat ash fall down from the stove, and motor 9 drives protection casing 12 regularly and rotates and can avoid the dry-heat ash to block up in ash pipe 5 below to a certain extent.
The stirring blades 11 are obliquely arranged on the stirring shaft 10, the inclination angle is smaller than 20 degrees, the oblique stirring blades 11 can temporarily form a cavity filled with magnetized air in the garbage during rotation, and the overall contact between the magnetized air and the garbage is further improved.
The edge of the stirring blade 11 is sharp-edged, so that the garbage can be cut to a certain degree in rotation, and crushing and degradation are facilitated.
The utility model provides an energy conversion device 6 produces the magnetization wind, recycles high energy magnetization air and carries out drying, carbonization and pyrolysis treatment to the organic waste in the rubbish, and the material is at first by dry pyrolysis after the magnetization, then reduces the harmful gas that the pyrolysis gasification and produce through the magnetization air volume that reduces the entering.
Because the garbage is accumulated in the furnace body 2, the carbonization area B is in an anoxic condition, organic wastes in the garbage are firstly carbonized and generate a large amount of heat, under the condition of high heat, the organic substances are continuously pyrolyzed and finally decomposed into carbon dioxide, water vapor and other small molecules and a small amount of residual ash, and the gasification pyrolysis is carried out at a low temperature below 350 ℃ by adopting magnetized air, so that the generation of harmful substances is basically eliminated, meanwhile, the high heat generated by spontaneous combustion of the materials is fully utilized, the energy consumption of equipment is very low, and the rapid reduction and the harmlessness of the garbage are really realized.
After the solid organic waste is sorted and put into equipment, the materials with the water content of more than 30% in the drying area A are dehydrated by the residual heat of pyrolysis of the bottom layer, the dry materials with the water content of less than 30% are pyrolyzed and gasified by magnetized air, the materials can be completely treated within 3-8 hours, ash residues which account for less than 1-2% of the total volume of the treated solid waste are generated, and the volume reduction reaches about 99%.
The garbage in the whole degradation furnace 1 is pyrolyzed into ash after being dried by waste heat, carbonized by oxygen deficiency and pyrolyzed at low temperature from top to bottom in the furnace, and the whole process makes full use of the waste heat and the magnetized air, so that the operation energy consumption is lower and the energy is more saved.
