In an embodiment, the drying device comprises a feeding conveyor belt, a dryer (hot blast stove, hot blast stove fuel system, saxophone, fan, pipeline, spray dust removal, sedimentation basin), a dryer discharge auger, a lifter, a distribution auger, etc. The gas generated after drying needs to be sprayed and dedusted, so that the dust content in the dried gas is reduced to reach the emission standard of dust in the atmospheric emission standard; the sedimentation tank aims at separating larger particles in gas by gravity, and the principle is that after flue gas enters a sedimentation chamber, the area is expanded, the speed is reduced, large particle dust falls to the bottom before the flue gas flows out of the sedimentation chamber due to high sedimentation speed, the dust is collected by a dust storage hopper at the bottom of the sedimentation chamber, and the undeveloped dust is carried out along with the flue gas.
Referring to fig. 1 and 2, the embodiment of the application further provides a method for utilizing landscaping garbage, which includes: sorting the landscaping garbage into a first type of landscaping garbage and a second type of landscaping garbage by using a sorting mechanical arm 111 of the sorting device; respectively crushing the first type of garden garbage into flaky or blocky garbage and crushing the second type of garden garbage into finely crushed garbage by using the crushing device; transferring the sheet-like or block-like waste to the granulator 123 using a first transfer device 121; preheating the fine garbage by using a preheating container 1221 on the second transferring device 122, and transferring the fine garbage preheated in the preheating container 1221 into the granulator 123; granulating the sheet-shaped or block-shaped garbage and the preheated finely divided garbage by using the granulator 123 to obtain biomass fuel.
In the technical scheme of the embodiment of the application, the landscaping garbage is sorted into the first type of landscaping garbage and the second type of landscaping garbage; the first type of garden garbage is used for crushing the garden garbage into flaky or blocky garden garbage, and the second type of garden garbage is used for crushing the garden garbage into fine crushing; during pelletization, the garden garbage crushed into fine particles is preheated in advance, so that lignin in the garden garbage becomes an adhesive to have certain adhesiveness, and the fine particles can play a role in adhesion in the pelletization machine 123, so that the sheet-shaped or block-shaped garbage can be adhered to obtain the biomass fuel. Compared with the prior art, the biomass fuel obtained in this way has compact and higher quality because the lignin with adhesiveness bonds the sheet garbage or the block garbage and is extruded into a whole under the action of the granulator 123.
Moreover, after the garden greening garbage is sorted into the first type of garden garbage and the second type of garden garbage, the garden garbage is respectively crushed into flaky or blocky garden garbage and finely crushed garden garbage, so that the garden greening garbage is purposefully sorted, sorted and crushed, and the crushing efficiency is improved. In an embodiment, in general, the first type of garden waste is a large-volume waste (suitable for being crushed into flakes or blocks) and the second type of garden waste is a smaller-volume waste (suitable for being crushed into fine particles).
As an optional implementation manner of the foregoing embodiment, the step of sorting the garden garbage into the first type of garden garbage and the second type of garden garbage by using the sorting mechanical arm 111 of the sorting device includes: identifying the landscaping garbage, and identifying the type of the landscaping garbage; the sorting mechanical arm 111 places the identified first type of garden garbage on the first conveyor belt 113; the sorting robot 111 places the identified second type of garden garbage on the second conveyor 112.
As an alternative to the above example, as shown in fig. 3, the sheet-like or block-like waste is dried before being fed to the granulator 123 and the finely divided waste is dried before being fed to the preheating vessel 1221.
As an alternative to the above embodiments, the second transferring device 122 includes a transferring robot arm, and the preheating container 1221 is disposed on the transferring robot arm;
the preheating of the fine garbage by the preheating vessel 1221 of the second transporting device 122 and transporting the preheated fine garbage in the preheating vessel 1221 to the granulator 123 include:
delivering the finely divided waste into the pre-heating container 1221 at a storage location for the finely divided waste;
the preheating vessel 1221 is moved to the feeding position of the granulator 123 by a transfer robot and the transfer robot is turned over to feed the fine waste in the preheating vessel 1221 into the granulator 123.
The above describes in detail a system and a method for utilizing landscaping garbage based on sorting and biomass fuel provided in the embodiments of the present application, and specific examples are applied to illustrate the principles and embodiments of the present invention, and the description of the above examples is only used to help understand the method and core ideas of the present invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in light of the ideas of the present invention, the present description should not be construed as limiting the present invention.
