Description

Technical Field

[0001] This invention relates to the field of funeral equipment technology, and in particular to an incinerator and incineration system. Background Technology

[0002] Burning sacrificial items to express grief for the deceased is a traditional Chinese funeral custom. However, open-air burning or other open-style burning methods cause serious air pollution, which deserves more attention, especially given the current severe environmental situation.

[0003] To address the aforementioned issues, closed-loop incinerators are now commonly used in China for incinerating relics. The incinerators are sealed for combustion, and the resulting flue gas is purified before being released into the atmosphere to reduce environmental pollution.

[0004] In the existing technology, there are various forms of incinerators. Currently, the most advanced and environmentally friendly incinerator is the multi-stage combustion incinerator. This multi-stage combustion incinerator is equipped with multiple combustion chambers, which are used for the combustion of solid sacrificial items, the initial combustion of combustion flue gas, and the purification combustion of flue gas. After multi-stage combustion, the combustion flue gas has a high degree of cleanliness and can meet environmental emission standards.

[0005] The applicant has discovered the following technical problems with the aforementioned multi-stage combustion incinerator: the locations of multiple combustion chambers are not reasonably set, each requiring a burner, and multiple burners need to work simultaneously during the combustion process, resulting in fuel waste. Summary of the Invention

[0006] The purpose of this invention is to provide an incinerator to solve the technical problem of fuel waste caused by unreasonable combustion chamber design in existing incinerators. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides an incinerator, comprising a first combustion chamber, a second combustion chamber, and a third combustion chamber connected in sequence. The first combustion chamber is located below the third combustion chamber, and the second combustion chamber is located between the first and third combustion chambers. The first combustion chamber has a first combustion air inlet and an ash outlet, and a first burner is installed inside. The second combustion chamber has a second combustion air inlet. The third combustion chamber has a third combustion air inlet and a flue gas outlet, and a second burner is installed inside. When the incinerator is in operation, the material to be incinerated first undergoes primary combustion in the first combustion chamber via the first burner, producing primary combustion ash and a high-temperature mixed gas. The primary combustion ash is discharged through the ash outlet. The high-temperature mixed gas flows through the second combustion chamber and mixes with combustion gas introduced through the second combustion air inlet for secondary combustion, producing secondary combustion ash and a low-temperature mixed gas. The secondary combustion ash slides into the first combustion chamber. The low-temperature mixed gas flows into the third combustion chamber and undergoes tertiary combustion via the second burner, producing combustion exhaust gas. The combustion exhaust gas is discharged through the flue gas outlet.

[0009] Optionally, the second combustion chamber is inclined, and the secondary combustion ash slides down the inclined inner wall of the second combustion chamber into the first combustion chamber.

[0010] Optionally, the cross-sectional area of ​​the third combustion chamber is larger than that of the second combustion chamber, and the flow velocity of the low-temperature mixed gas decreases after flowing into the third combustion chamber from the second combustion chamber.

[0012] Optionally, a grate is also provided in the first combustion chamber. The grate is rotatable. When the incinerator is working, the material to be incinerated is first burned on the grate. After the first combustion is completed, the grate is rotated to unload the ash from the first combustion and / or the ash from the second combustion to the bottom of the first combustion chamber, and then discharged through the ash outlet.

[0013] The beneficial effects of the incinerator in this embodiment of the invention are as follows: by optimizing the position of the three incineration chambers, the number of burners used is reduced, and fuel consumption is saved while ensuring incineration efficiency and clean flue gas.

[0014] Another object of the present invention is to provide an incineration system to solve the technical problem of high fuel consumption in existing incineration systems. The incineration system of the embodiments of the present invention relies on the aforementioned incinerator to solve this technical problem.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] This invention provides an incinerator, such as... Figure 1 The diagram shown is a cross-sectional view of an incinerator according to an embodiment of the present invention, including a first combustion chamber 1, a second combustion chamber 2, and a third combustion chamber 3 connected in sequence. The first combustion chamber 1 is located below the third combustion chamber 3, and the second combustion chamber 2 is located between the first combustion chamber and the third combustion chamber. The first combustion chamber 1 is provided with a first combustion air inlet 11 and an ash outlet 12, and a first burner 13 is provided inside. The second combustion chamber 2 is provided with a second combustion air inlet 21. The third combustion chamber 3 is provided with a third combustion air inlet 31 and a flue gas outlet 32, and a second burner 33 is provided inside.

[0026] When the incinerator of this embodiment of the invention is working, the material to be incinerated is first ignited by the first burner 13 in the first combustion chamber 1 for primary combustion, producing primary combustion ash and high-temperature mixed gas. The primary combustion ash is discharged through the ash outlet 12. When the high-temperature mixed gas flows through the second combustion chamber 2, it mixes with the combustion-supporting gas introduced by the second combustion air outlet 21 for secondary combustion, producing secondary combustion ash and low-temperature mixed gas. The secondary combustion ash slides into the first combustion chamber 1. The low-temperature mixed gas flows into the third combustion chamber 3 and is ignited by the second burner 33 for tertiary combustion, producing combustion exhaust gas. The combustion exhaust gas is discharged through the flue gas outlet.

[0027] Specifically, in the above embodiments, the material to be burned can be cotton and linen clothing, shoes and hats, blended fabrics, paper products, and non-metallic sacrificial offerings, etc. The first burner 13 and the second burner 33 can be burners of the same or different specifications and models. For ease of parts procurement, it is preferable to use gas burners of the same specifications, such as the FS-10 automatic electronic ignition burner. The combustion-supporting gas can be oxygen or air; from a cost-saving perspective, air is preferred.

[0028] The specific working process of the incinerator according to the above embodiments of the present invention is as follows: (1) The material to be incinerated is put in according to the volume of the first combustion chamber; (2) Combustion-supporting gas is introduced into the first combustion chamber, the second combustion chamber, and the third combustion chamber through the first combustion-supporting air inlet, the second combustion-supporting air inlet, and the third combustion-supporting air inlet; (3) The first burner is ignited to ignite the material to be burned. Then the first burner is extinguished and the material to be burned spontaneously combusts in the environment where the combustion-supporting gas is introduced. The temperature in the first combustion chamber rises instantly to over 600°C. (4) The first combustion chamber produces a high-temperature mixed gas containing combustible gas and fly ash. When this mixed gas enters the second combustion chamber, its temperature is above 600°C, which is enough to reach the ignition point of some combustible and harmful gases. However, it does not burn because of the low content of the combustion-supporting gas. This high-temperature mixed gas enters the second combustion chamber and mixes with the combustion-supporting gas introduced through the second combustion air inlet, resulting in instantaneous combustion and secondary combustion. This mixed gas basically completes combustion and its temperature decreases when it flows from the first section of the second combustion chamber to the end of the second combustion chamber. After secondary combustion in the second combustion chamber, the content of combustible and harmful gases and fly ash in the low-temperature mixed gas entering the third combustion chamber is greatly reduced, and it cannot burn on its own under the action of the combustion-supporting gas.

[0029] (5) The second burner is ignited and continues to work. After the low-temperature mixed gas enters the third combustion chamber, it undergoes three combustions under the scorching of the second burner, further reducing the content of combustible and harmful gases and fly ash contained therein.

[0030] (6) The combustion exhaust gas after three combustions is discharged through the flue gas outlet. At this time, more than 90% of the combustible harmful gases and dust in the combustion exhaust gas are removed.

[0031] The beneficial effects of the incinerator according to the above embodiments of the present invention are as follows: By setting the three combustion chambers vertically, the second combustion chamber makes full use of the high-temperature characteristics of the exhaust gas after combustion in the first combustion chamber. Only the combustion-supporting gas needs to be introduced to allow the exhaust gas to undergo secondary combustion and purification. While ensuring the flue gas purification effect, it effectively reduces the number of burners and, more importantly, saves valuable fuel consumption, meeting the design requirements for energy conservation and environmental protection.

[0032] As an optional implementation method, based on the above implementation method, such as... Figure 2 The diagram shown is a cross-sectional schematic of an incinerator according to another embodiment of the present invention. In this embodiment, the second combustion chamber 2 is inclined, and the secondary combustion ash slides down the inclined inner wall of the second combustion chamber into the first combustion chamber. One of the advantages of the inclined arrangement of the second combustion chamber 2 is that it can increase the length of the second combustion chamber, thereby increasing the combustion time of the high-temperature mixed gas in the second combustion chamber, making the combustion more complete and the flue gas cleaner. Another advantage is that secondary combustion produces too much combustion ash, and long-term combustion accumulation in the combustion chamber will affect the combustion effect. The inclined arrangement of the second combustion chamber allows the combustion ash to slide down into the first combustion chamber on its own after accumulating to a certain thickness, and then be discharged through the ash outlet, effectively reducing the frequency of manual cleaning.

[0033] As an optional implementation method, such as Figure 1-2 As shown, the cross-sectional area of ​​the third combustion chamber 3 is larger than that of the second combustion chamber 2. The flow velocity of the low-temperature mixed gas decreases after flowing into the third combustion chamber 3 from the second combustion chamber 2.

[0034] Specifically, in order to ensure that the length and width of the incinerator are consistent, the second combustion chamber and the third combustion chamber preferably have the same cross-sectional dimensions, but the height of the third combustion chamber is greater than the height of the second combustion chamber.

[0035] The beneficial effects of the incinerator described above are as follows: the combustion flue gas in the second combustion chamber undergoes active combustion, resulting in a relatively fast combustion rate. Therefore, the flow velocity of the combustion flue gas within this chamber can be relatively high. In contrast, the combustion flue gas in the third combustion chamber undergoes passive combustion and is the final combustion and purification process, thus requiring a relatively slower flow velocity. Since the flow rate of flue gas per unit time within the incinerator is constant, a larger cross-sectional area in the incinerator results in a slower flow velocity of the combustion flue gas. Therefore, the cross-sectional area of ​​the third combustion chamber is set to be larger than that of the second combustion chamber to ensure complete combustion of the combustion flue gas within the third combustion chamber.

[0036] As an optional implementation, refractory insulation layers are provided on the inner walls of the first combustion chamber 1, the second combustion chamber 2, and the third combustion chamber 3. Specifically, the refractory insulation layers are preferably made of lightweight, fast-heating 120mm thick ceramic fiber modules. The refractory insulation layers can prevent heat leakage from the incinerator, ensure normal combustion inside the furnace, and also prevent accidental burns.

[0037] As an optional implementation method, such as Figure 1-2 As shown, the first combustion chamber of the incinerator in this embodiment is also equipped with a grate 14. The grate 14 can be rotated. When the incinerator is working, the material to be incinerated first undergoes combustion on the grate 14. After the first combustion is completed, the grate 14 rotates to discharge the ash from the first combustion and / or the ash from the second combustion to the bottom of the first combustion chamber 1, and then discharges it through the ash outlet 12. The arrangement of the grate 12 firstly ensures that the material to be incinerated is in full contact with the combustion-supporting gas for rapid combustion, and secondly, it can rotate to quickly discharge the incineration ash to the bottom of the first combustion chamber.

[0038] As an optional implementation, a furnace door is also provided on the first combustion chamber, and the furnace door is designed to be airtight with the first combustion chamber when closed. The furnace door facilitates the direct placement of the material to be incinerated into the first combustion chamber.

[0039] As an optional implementation, the first combustion chamber is also provided with an observation port, through which the combustion status of the material to be burned can be observed.

[0040] This invention provides an incineration system, such as... Figure 3 The diagram shown is a structural schematic of an incineration system according to an embodiment of the present invention, including a flue gas purification device, a slag and dust removal device 300, an air supply device, a fuel device 500, an electrical control device 600, and an incinerator 100 as described in any of the above embodiments. The flue gas purification device is connected to a flue gas outlet, and combustion exhaust gas enters the flue gas purification device through the flue gas outlet. The air supply device is connected to the incinerator 100 to provide combustion-supporting gas for combustion within the incinerator 100. The connection between the air supply device and the flue gas purification device enables the incinerator 100 and the flue gas purification device to... The internal pressure of the incineration device is negative; the slag and dust removal device 300 is connected to the incinerator 100 and the flue gas purification device respectively, collects the dust generated by the flue gas purification device and transports the dust to the incinerator 100; the fuel device 500 is connected to the first burner and the second burner respectively, and provides fuel to the first burner and the second burner; the electrical control device 600 is connected to the flue gas purification device, the slag and dust removal device 300, the air supply device, the fuel device 500, the first burner and the second burner respectively, and controls their working status.

[0041] Specifically, the fuel storage device preferably uses a gaseous fuel storage device, such as a natural gas tank.

[0042] Specifically, the slag and dust removal device 300 preferably uses a conveying auger, which is driven by a motor with a preferred motor power of 1.5Kw.

[0043] Specifically, the electrical control device 600 preferably uses a PLC programmable controller.

[0044] The specific operating mode of the incineration system described above is as follows: (1) When the incinerator is working, the electrical control device controls the fuel device and the air supply device to provide fuel and combustion gas for the normal operation of the incinerator; (2) Gas circulation in the incineration system, the electric control device controls the operation of the air supply device and the flue gas purification device, forming a negative pressure in the system, and the incineration flue gas flows from the incinerator into the flue gas purification device and is finally discharged. (3) Dust collection: The electrical control device controls the operation of the slag removal and dust removal device to transfer the dust generated by the flue gas purification device to the incinerator. (4) Ash removal: After the incinerator has finished burning, the system stops running and the ash, slag and dust are transported out for treatment through the ash outlet of the incinerator.

[0045] The beneficial effects of the incineration system of this invention are that, firstly, the incinerator using any of the above-described embodiments can save fuel; secondly, by setting up each functional module in accordance with the structural characteristics of the above-described incinerator, the cleanliness of the flue gas generated by incineration is greatly improved.

[0046] As an optional implementation method, such as Figure 3 As shown, based on the above embodiment, the air supply device includes an induced draft fan 410, a blower 420, a chimney 430, and pipelines. One end of the induced draft fan 410 is connected to the flue gas purification device through the pipeline, and the other end of the induced draft fan 410 is connected to the chimney 430. The blower 420 is connected to the first combustion air inlet, the second combustion air inlet, and the third combustion air inlet through pipelines, respectively, for providing combustion-supporting gas for combustion in the incinerator.

[0047] Specifically, the first combustion air inlet includes a bottom air inlet and two side air inlets. The bottom air inlet is located at the bottom of the first combustion chamber of the incinerator 100, and the two side air inlets are respectively located on two adjacent or opposite sides of the first combustion chamber.

[0048] The pipeline is equipped with a bellows, and the blower is connected to the bellows through the pipeline. First, the blower blows the air into the bellows. The bellows then outputs air in five directions, which are respectively connected to the bottom air outlet, two side air outlets, the second combustion air outlet, and the third combustion air outlet. Each air duct is equipped with a valve, which can be manually controlled or opened and closed or the flow rate can be controlled according to the control quality of the electronic control device 600.

[0049] As an optional implementation method, such as Figure 3As shown, based on the above embodiments, the flue gas purification device includes a flue gas cooler 210, a cyclone dust collector 220, and a bag filter 230 connected in sequence. The flue gas cooler 210 is connected to the flue gas outlet, and the combustion exhaust gas enters the flue gas cooler 210 through the flue gas outlet. The bag filter is connected to the induced draft fan.

[0050] The specific working process of the above-mentioned flue gas purification device is as follows: Under the action of the induced draft fan 410, the combustion exhaust gas in the incinerator 100 enters the flue gas cooler 210 through the flue gas outlet. After being cooled down by the flue gas cooler 210, the combustion exhaust gas enters the cyclone dust collector 220. Large dust particles in the combustion exhaust gas are decelerated by friction with the cylinder wall in the cyclone dust collector 220 and finally slide down to the slag removal and dust removal device 300 to complete the first purification filtration. The combustion exhaust gas filtered by the cyclone dust collector enters the bag dust collector 230 for secondary filtration, further filtering the micro dust that the cyclone dust collector 220 cannot filter. The bag filter 230 includes two relatively enclosed and isolated chambers. The lower chamber is the dust chamber, where dust in the combustion flue gas is filtered through the filter bags and retained in the dust chamber. The upper chamber is the clean air chamber, where the inlet of the induced draft fan 410 is connected to the clean air chamber, so that the exhaust gas is clean air. The bag filter 230 also includes an air compressor, which periodically blows the filter bags of the bag filter 230 to remove the dust adhering to the surface of the filter bags.

[0051] As an optional implementation method, such as Figure 3 As shown, based on the above embodiments, the incineration system of this embodiment also includes a generator 700, which is connected to the fuel device 500 and generates electrical energy through fuel combustion; the power output terminal of the generator 700 is connected to the electrical control device 600 to provide electrical energy for the overall operation of the incineration system.

[0052] The beneficial effect of this implementation method is that, in some open-air environments where external power cannot be provided, the generator can ensure the normal operation of the incineration system. Furthermore, in regions like Tibet, where oil and gas resources are abundant but electricity resources are scarce, the generator is more suitable for use in Tibetan areas.

[0053] As an optional implementation method, such as Figure 3 As shown, based on all the above embodiments, the incineration system of this embodiment also includes a movable frame 800, and the flue gas purification device, slag removal and dust removal device, air supply device, fuel device, electrical control device, incinerator and generator are all installed in the frame 800.

[0054] The movable frame 800 facilitates the transportation of the incineration system, enabling it to be applied in more scenarios and across a wider range.

[0055] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
