Description

Technical Field

[0001] The present invention relates to a garbage treatment device, and in particular to an incineration treatment module for small modular collaborative treatment of various garbage. Background Art

[0002] At present, a small-scale, modular, highly flexible and adaptable small mobile garbage incineration system has not yet formed a mature market scale. However, there are many demands for harmless treatment of various garbage in areas with inconvenient transportation, small and discontinuous garbage treatment volumes. Therefore, the small modular multi-garbage incineration treatment system is a development direction with a broad market and urgent demand.

[0003] Publication No. CN 104061576 B, patent name "Vehicle-mounted garbage incinerator" discloses a vehicle-mounted garbage incinerator. This technical solution has the following disadvantages: First, the furnace bed cannot adjust the incineration of garbage on the bed layer, making it difficult to ensure the burnout rate;

[0004] Second, the slag discharge bed does not consider cooling measures, which will cause damage to the equipment during actual operation;

[0005] Third, since the technical solution is vehicle-mounted, the space is necessarily limited. And it adds equipment such as heat exchangers, desulfurization and deodorization devices, and dust collectors in the technical solution, with many components, which is difficult to achieve in reality. Summary of the Invention

[0006] Object of the Invention: The object of the present invention is to provide an incineration treatment module for small modular collaborative treatment of various garbage, which is suitable for harmless incineration of various garbage in a small modular multi-garbage collaborative treatment system.

[0007] Technical Solution: To achieve the above object, the present invention adopts the following technical solution: An incineration treatment module for small modular collaborative treatment of various garbage, comprising:

[0008] A box body, and arranged inside the box body are:

[0009] An incinerator furnace, arranged inside the box body and adjacent to one end of the box body. The top of the incinerator furnace is connected to a sludge direct combustion feed port opened in the upper part of the box wall at one end of the box body through a sludge feeding device;

[0010] A cloth device, located at the front end of the incinerator furnace. The feed port of the cloth device is connected to a mixed solid waste feed port arranged on the box wall at one end of the box body through a pipeline. The cloth port of the cloth device evenly spreads the conveyed mixed solid waste on a mechanical incinerator grate located at the lower end of the incinerator furnace for combustion treatment;

[0011] The secondary combustion chamber for flue gas, one end of which is connected to the rear end of the furnace chamber of the incinerator, and the other end extends towards the other end of the box until it is connected to the incineration hot flue gas outlet provided on the top box wall of the box;

[0012] The ash hopper is arranged at the lower end of the mechanical incinerator grate and is used to collect the ash after incineration; the lower part of the ash hopper is connected to the slag discharge port opened at the bottom of the side box wall of the box through a slag discharge device;

[0013] The primary air control pipeline and the secondary air control pipeline, wherein,

[0014] The primary air control pipeline penetrates through the middle of the ash hopper and is used to provide the necessary air volume for efficient combustion in the furnace chamber of the incinerator and air cooling of the mechanical incinerator grate;

[0015] The secondary air control pipeline penetrates through the secondary combustion chamber for flue gas and is used to provide the required air volume for the secondary combustion chamber for flue gas;

[0016] The primary and secondary air inlet main pipeline is located at the rear end of the furnace chamber of the incinerator. One end of the primary and secondary air inlet main pipeline is connected to the primary and secondary air inlets opened on the top of the box, and the other end of the primary and secondary air inlet main pipeline is divided into two air inlet branch pipes. One air inlet branch pipe is connected to the primary air control pipeline, and the other air inlet branch pipe is connected to the secondary air control pipeline.

[0017] Further, the mechanical incinerator grate includes: a frame structure, a fixed grate, a sliding grate and a driving assembly. Among them, the fixed grate and the sliding grate are arranged alternately on the frame structure, and the sliding grate is driven by the driving assembly to reciprocate; the driving assembly includes: a driving motor, whose driving shaft is connected to the input shaft of the reducer,

[0018] A driving crankshaft, the end of which is connected to the output shaft of the reducer;

[0019] A rocker connecting rod, one end of which is installed on the driving crankshaft and the other end is connected to the sliding grate.

[0020] Further, the slag discharge device is a series-connected two-stage water-cooled spiral slag discharge device. The upper part of the series-connected two-stage water-cooled spiral slag discharge device is connected to the ash hopper and adopts a two-stage spiral conveying structure. The first stage consists of two series-connected water-cooled spiral parts. Each water-cooled spiral part is divided into a horizontal section and an inclined section to cool the ash slag and first convey it horizontally and then lift it; the two water-cooled spiral parts are respectively connected to the second-stage spiral conveying mechanism, and the aggregated ash slag is lifted again and discharged out of the system through the slag discharge port.

[0021] Further, a plurality of burners are symmetrically arranged in the incinerator furnace, providing guarantee for the start-up combustion of the materials and maintaining efficient combustion in the incinerator furnace.

[0022] Further, a number of combustion detection measuring points are arranged in the incinerator furnace for monitoring the combustion condition in the incinerator, and the combustion condition includes the temperature of the incinerator furnace, the flame line and the uneven combustion condition.

[0023] Further, in the feeding device, the mixed solid waste conveyed by the secondary spiral material conveyor is evenly distributed on the mechanical incinerator grate through the material pushing blades.

[0024] Further, a temperature monitoring device and a burner are arranged in the secondary combustion chamber of the flue gas to ensure that the temperature of the flue gas combustion in the secondary combustion chamber of the flue gas ≥ 850 °C.

[0025] Further, the box body is a standard container.

[0026] Beneficial effects: First, the layout is ingenious; it is extremely difficult to develop and design a complete system that combines incineration, slag discharge, and secondary combustion of flue gas in the extremely limited space of a standard container. The conventional waste incineration system is vertically arranged, with a huge vertical drop from the waste feeding hopper to the slag discharge device. The present invention develops and designs all equipment, achieving the horizontal arrangement of the incinerator system to meet the space requirements of the container without reducing its original treatment effect.

[0027] Second, the structure is compact; the present invention first adjusts the conventional feeding from above the incinerator to feeding from the front end of the incinerator and entering the incinerator through the feeding device, reducing the height of the incineration system in the vertical direction; secondly, the incinerator is changed from the conventional hydraulic drive to a motor drive suitable for it, improving the control accuracy while eliminating the configuration of the hydraulic station, thereby reducing the internal use space; then, the slag discharge device is changed from the conventional structure of a scraper conveyor connected to a slag skimmer to a row-connected secondary water-cooled spiral slag discharge device, avoiding internal environmental pollution caused by ash leakage and further reducing the height of the incineration system in the vertical direction; finally, the secondary combustion chamber of the flue gas is changed from the conventional vertical arrangement to a horizontal and inclined arrangement, effectively utilizing the horizontal space of the container while reducing the height of the incineration system in the vertical direction. Thus, the purpose of arranging a complete incineration system in a limited narrow space is achieved.

[0028] Third, the burnout rate is high; the mechanical incinerator grate applied in the present invention is a mechanical incinerator grate furnace with fixed grates and sliding grates arranged alternately. Through the reciprocating movement of the sliding grates, the effects of stirring the materials and pushing the materials forward can be achieved simultaneously.

[0029] Fourth. Consider cooling measures for slag discharge. The present invention adopts a series-connected two-stage water-cooled spiral slag discharge device. The cooling water of the series-connected two-stage water-cooled spiral slag discharge device enters the device through the cooling water inlet K04 and leaves the device through the hot water outlet K03, avoiding damage to the equipment caused by high slag discharge temperature and extending the service life of the equipment.

[0030] Fifth. Improve the structure of the mechanical incinerator grate. While retaining the advantages of the large-scale mechanical reciprocating grate furnace for waste incineration, the structure is greatly simplified to best suit the needs of the small modular multi-waste collaborative treatment system. It uses a symmetric motor combined with a helical gear reducer and a crank rocker structure to provide the drive assembly, eliminating the space occupied by the hydraulic station for hydraulic drive. Sixth. Ensure the safety of operators and the surrounding environment. The furnace chamber of the incinerator and the secondary flue gas combustion chamber use refractory materials, and the slag discharge device uses a water-cooled method to ensure that there is no excessive heat radiation in the module and avoid potential safety hazards to personnel caused by the module.

[0031] Seventh. Protection measures for the furnace chamber of the incinerator. When the temperature of the furnace chamber of the incinerator is too high in the short term, the temperature of the furnace chamber of the incinerator can be controlled by spraying sludge; if dealing with waste with a relatively high calorific value for a long time, a water-cooled or semi-water-cooled mechanical grate furnace can be considered to control the temperature of the grate body by water cooling; or the two can be combined to protect the furnace chamber and grate of the incinerator from high-temperature corrosion and extend the service life.

[0032] Eighth. Adopt a modular box structure, cooperate with other small-scale multi-waste collaborative treatment modules, and effectively carry out harmless treatment of various wastes.

[0033] Ninth. As an incineration treatment module, it can also be used alone to incinerate solid and fluid waste.

[0034] Tenth. The modular and skid-mounted design (using a standard container as the carrier) enables the incineration treatment module to be conveniently and quickly transported to the required application scenarios. Description of the Drawings

[0050] The present invention will be further described below in conjunction with the accompanying drawings: The present invention discloses an incineration treatment module for collaborative treatment of various types of waste in a small modular manner, and this device is a part of the small modular collaborative waste treatment system.

[0051] As Figure 1 shown; a mixture of various solid wastes and fluid wastes (taking sludge as an example) enter this module for harmless incineration treatment. After treatment, the waste heat of the hot flue gas generated in the module is utilized by the waste heat utilization module 5. The ash residue after the solid waste incineration treatment is discharged outside this module. Signals are collected inside the module and fed back to the central control module 1, and it is centrally controlled by the central control module 1. Moreover, the power required for this module is provided by the mobile generator set module 2, as Figure 2 shown.

[0052] As Figure 1 shown, the incineration treatment module for collaborative treatment of various types of waste in a small modular manner of the present invention uses a standard container as a carrier, mainly for the convenience of transportation, including land transportation, sea transportation, and air transportation. Different specifications of containers are selected according to different waste treatment amounts, such as 40-foot general container, 40-foot high cube container, or 45-foot high cube container, etc.

[0053] As Figure 4 shown, several doors for people to enter and exit can be opened at different positions of the container as needed. Several interfaces are opened on the container, specifically: the mixed solid waste processed in the feed pretreatment module enters this module through the mixed solid waste feed port K02, and the sludge under appropriate conditions enters the furnace chamber of the incinerator in this module through the sludge direct combustion feed port K01. The primary and secondary air required inside the module enters through the primary and secondary air inlet K06. The cooling water of the series-connected secondary water-cooled spiral slag discharge device enters this device through the cooling water inlet K04 and leaves this device through the hot water outlet K03. The hot flue gas generated in the incinerator is discharged from this module through the hot flue gas outlet K05, and the ash residue that has been burned out and cooled in the incinerator is discharged from this module through the slag discharge port K07.

[0054] As Figure 3 Figure 8 shown, the incineration treatment module can be specifically described as:

[0055] A sludge feeding device 403 is arranged at the top of the furnace chamber 405 of the incinerator. The front end of the sludge feeding device 403 is connected to the sludge feeding connecting pipe section L03. Under appropriate conditions, the sludge conveyed by the sludge direct combustion material conveying pipeline 302 is sprayed into the furnace chamber of the incinerator at different positions by the opening and closing of the main pipe control valve and each branch pipe control valve of the sludge feeding device 403, and falls on the mechanical incinerator grate 406 for direct combustion treatment of the sludge;

[0056] The front end of the cloth device 404 is connected to the solid waste feeding connection section L02, and the rear end is the incinerator furnace chamber 405 and the mechanical incinerator grate 406. Through the regular movement of the material spreading blades in the device, the mixed solid waste conveyed by the secondary spiral conveyor 301 is evenly distributed on the mechanical incinerator grate 406, facilitating its efficient harmless incineration treatment in the incinerator furnace chamber 405;

[0057] The incinerator furnace chamber 405 and the mechanical incinerator grate 406 at the lower end form the core of the incineration module. The front end of the incinerator furnace chamber 405 is connected to the mechanical incinerator grate 406, a sludge feeding device 403 is arranged at the upper end, and the rear end is connected to the flue gas secondary combustion chamber 411. A number of burners are symmetrically arranged on both sides of the incinerator furnace chamber. In this embodiment, there are 4 burners, which provide guarantee for the start-up combustion of the material and the efficient combustion in the incinerator furnace chamber. There are several combustion detection measuring points in the incinerator furnace chamber for monitoring the combustion conditions in the incinerator furnace chamber, including the temperature of the incinerator furnace chamber, the fire line, the uneven combustion condition, etc.;

[0058] The mechanical incinerator grate 406 is composed of a frame structure, a fixed grate, a sliding grate, a driving component, etc. While retaining the advantages of the large-scale waste incineration mechanical reciprocating incinerator grate furnace, its structure is greatly simplified to make it best adapt to the needs of the small modular multi-waste collaborative treatment system, such as Figure 7 shown, it uses a symmetric motor combined with a helical gear reducer and a crank rocker structure to provide the driving component, eliminating the space occupied by the hydraulic station with hydraulic drive;

[0059] The mechanical incinerator grate furnace is designed with different mechanical incinerator grate design schemes such as air-cooled mechanical incinerator grate, water-cooled mechanical incinerator grate and semi-water-cooled mechanical incinerator grate, and the corresponding appropriate mechanical incinerator grate structure is adopted according to different application requirements;

[0060] There is an ash hopper 407 below the mechanical incinerator grate. The primary air control pipeline passes through the middle of the ash hopper 407, which provides the necessary air volume for the efficient combustion in the incinerator furnace chamber and the air cooling of the mechanical incinerator grate bars. At the same time, the ash hopper collects the incinerated ash and slag and drops it onto the row-connected secondary water-cooled spiral slag discharge device 409;

[0064] A temperature monitoring device and a burner are provided in the secondary combustion chamber 411 of the flue gas to ensure that the temperature of the flue gas combustion in the secondary combustion chamber

[0065] of the flue gas 411 is ≥ 850 °C, and the length of the pipeline of the secondary combustion chamber 411 of the flue gas is designed and determined according to the flue gas experiencing ≥

[0066] 2 s;

[0067] The hot flue gas discharged from the incinerator furnace passes through the secondary combustion chamber 411 of the flue gas and is sent to the waste heat utilization module 5 through the hot flue gas outlet K05;

[0068] The upper part of the row-connected two-stage water-cooled spiral slag discharging device 409 is connected to the ash hopper 407. Adopting a two-stage spiral conveying method, the first stage is composed of two row-connected water-cooled spiral parts. Each water-cooled spiral part is divided into a horizontal section and an inclined section to cool the ash and slag and first convey it horizontally and then lift it; the two water-cooled spiral parts are respectively connected to the second-stage spiral conveying mechanism, and the aggregated ash and slag are lifted again and discharged out of the system through the slag discharging port K07 of the furnace slag.

[0069] The slag discharging device of the present invention is set to two stages for the following purposes: 1. Collection, collecting the ash and slag collected by the ash hoppers on both sides into a spiral conveyor and discharging them together from the incineration module;

[0070] 2. Lifting height, the horizontal section of the first-stage water-cooled spiral is located below the ash hopper to collect ash and slag, while the inclined section of the first-stage water-cooled spiral and the second-stage spiral conveying mechanism can lift the ash and slag to a certain height and discharge them from the incineration module, facilitating the external acceptance of ash and slag;

[0071] As Figure 9 shown, the material flow direction during the operation of the incineration treatment module is as follows:

[0072] The mixed garbage enters the incinerator furnace 405 through the cloth feeding device 404 from the mixed solid waste feeding port K02 and is fully burned under the agitation and pushing of the mechanical incinerator grate 406;

[0073] Under suitable conditions, the sludge is sprayed into the incinerator furnace 405 through the sludge feeding device 403 from the direct combustion feeding port K01 and is incinerated together with the mixed garbage;

[0074] The ash and slag generated during the incineration of the mixed garbage or together with the sludge enter the row-connected two-stage water-cooled spiral slag discharging device 409 through the ash hopper 407 and are discharged from the incineration treatment module through the slag discharging port K07 after cooling;

[0075] The flue gas generated during the incineration of mixed waste or sludge is discharged from the incineration treatment module through the hot flue gas outlet K05 after being treated in the flue gas secondary combustion chamber;

[0076] The air extracted for the primary and secondary air enters the main pipeline 412 through the air inlet K06, and then passes through the primary air control pipeline

[0077] 408 and the secondary air control pipeline 410 enter the incinerator furnace 405 and the flue gas secondary combustion chamber 411 respectively, supplying the required air volume for their treatment.
