Abstract
The invention discloses a sorting method for domestic garbage before power generation and incineration, which comprises the following steps: a. conveying garbage at uniform speed and with uniform quantity to a first manual sorting device for first manual sorting; b. placing the garbage after the first manual sorting into a drum bag-breaking screening device for sorting; c. sending out the sorted undersize for land-fill, and sending the sorted oversize to a second manual sorting device for second manual sorting; d. sending the sorted oversize after the second manual sorting to a material pit. The sorting method has uniform feeding, thereby increasing the calorific value of the garbage into a furnace and effectively improving the resource utilization rate.
Description
Technical field
The present invention relates to a kind of sorting consumer waste processing method, particularly a kind of sorting method for domestic garbage before power generation and incineration.
Background technology
In the last few years, the waste incineration and generating electricity treatment industry technical merit of China improves constantly, but sorting process does not give enough attention before burning to garbage power, caused the waste of the burning electricity generation factory actual motion cost height and the energy: have plenty of and do not pass through preceding sorting process, just directly primary house refuse is fed incinerator, caused refuse thermal value low, the auxiliary fuel consumption is big, incinerator is short service life, and the flying dust amount is big, tail gas concentration height; It is inhomogeneous to have plenty of in the preceding sorting process technology feed, there are not resource recovery link or resource recovery low, cause separating effect poor, cost performance is low, though also play a role, but can not move the condition in earlier stage that provides preferably really long-term, practical, economically for the garbage incinerating power plant of China.
Summary of the invention
The present invention is for solving the sorting method for domestic garbage before power generation and incineration that the technical problem that exists in the known technology provides a kind of calorific value that can improve stove rubbish into, improves separating effect.
The present invention for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind of sorting method for domestic garbage before power generation and incineration may further comprise the steps: a, with rubbish at the uniform velocity, all amount being transported to first manual sorting's conveying device carries out manual sorting's first time; B, will insert the drum broken bag screening plant through manual sorting's rubbish for the first time and carry out sorting; C, will send landfill, will deliver to second manual sorting's conveying device through the oversize after the sorting and carry out manual sorting's second time through the screenings after the sorting; D, will carry the pan feeding hole through manual sorting's oversize for the second time.
The present invention can also adopt following technical measures:
Above-mentioned sorting method for domestic garbage before power generation and incineration is characterized in: before the described steps d, carry out the magnetic force sorting process by magnetic grader before oversize is carried the pan feeding hole.
Above-mentioned sorting method for domestic garbage before power generation and incineration is characterized in: among the described step c, the screenings after the sorting is sent by reversible conveyor.
Above-mentioned sorting method for domestic garbage before power generation and incineration is characterized in: in the described steps d, manual sorting's oversize is sent by reversible conveyor through the second time.
Advantage and good effect that the present invention has are: (1) feed is even; (2) broken bag and screening realize by an operation, reduce equipment cost; (3) improve resource utilization effectively; (4) improved the calorific value that advances stove rubbish; (5) reduced the waste of the energy; (6) the flying dust generation is little, reduces the flying dust disposal cost; (7) take into full account the operation convenience that the incinerator feed is grabbed bucket; (8) take into full account the operation convenience that garbage truck is transported outward landfill; (9) prolong various incinerator service life; (10) in the service life of prolongation tail gas from incinerator treatment facility, reduce its maintenance cost; (11) reduce burning electricity generation factory production cost.
Description of drawings
Fig. 1 uses device structure schematic diagram of the present invention;
Fig. 2 is a process flow diagram of the present invention.
Among the figure: 1, hopper, 2, board-like conveying device, 3, the uniform distribution machine, 4, manual sorting's conveying device, 5, drum broken bag screening plant, 6, manual sorting's conveying device, 7, the magnetic force sorting, 8, promote conveying device, 9, reversible conveyor, 10, the screenings conveying device that connects material, 11, the landfill material reversible conveyor, 12, dustbin, 13, material hole.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of sorting method for domestic garbage before power generation and incineration of the present invention may further comprise the steps: a, with rubbish at the uniform velocity, all be transported to first manual sorting's conveying device and carry out manual sorting's first time to amount; The present invention cooperates by board-like conveying device 2 and uniform distribution machine 3 or the hydraulic stepping batcher realizes that feed is even, is convenient to follow-up manual sorting; The manual sorting can remove the big part inorganic matter and the various chaff interference of fire-retardant thing and interfere with subsequent mechanical treatment, prolongs various incinerator service life.
B, will insert the drum broken bag screening plant through manual sorting's rubbish for the first time and carry out sorting; Broken bag and screening realize by an operation, reduce equipment cost, have also reduced the maintenance workload of equipment.The present invention can sift out less fire-retardant things such as dust owing to adopted the drum broken bag screening plant, and the flying dust generation is little in the time of can making waste incineration, tail gas concentration is low, thereby reduced the expense that flying dust is handled, prolonged the service life of tail gas from incinerator treatment facility, reduced its maintenance cost.
C, will send landfill, will deliver to second manual sorting's conveying device through the oversize after the sorting and carry out manual sorting's second time through the screenings after the sorting.Screenings after the sorting is sent by reversible conveyor, has improved operating efficiency, also is convenient to take into full account the operation convenience of garbage truck outward transport landfill.
D, will carry the pan feeding hole through manual sorting's oversize for the second time.Before oversize is carried the pan feeding hole, carry out the magnetic force sorting process, ferrous metal is sorted out when utilizing again, avoid incinerator being had a negative impact because of it enters in the stove by magnetic grader, thus the service life of prolongation incinerator.
E, process manual sorting's oversize are for the second time sent by reversible conveyor, by two conveying devices oversize are thrown into two zones in material hole more respectively by two charging apertures.Avoid because of a charging aperture causes grab bucket work frequent, bring convenience for the actual motion and the management of the grab bucket of incinerator feed.
In sum: the present invention improves resource utilization effectively, has improved the calorific value that advances stove rubbish, has reduced the waste of the energy and has reduced the production cost of burning electricity generation factory.
