DETAILED DESCRIPTION
[0029] The utility model is further described below in conjunction with the accompanying drawings:
[0030] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0031] like Figures 1 to 5The multi-purpose smokeless boiler shown includes a furnace body 100 with a cavity inside; an inner furnace 200 is arranged in the cavity; a return structure 300 is arranged on one side of the inner furnace 200, and one end is connected to the inner furnace 200; a metal hose 400 is arranged in the cavity, adjacent to the inner furnace 200 and / or the return structure 300; wherein the cavity and the metal hose 400 are filled with flowing water.
[0032] Optionally, a plurality of support members are provided on the outer side walls of the inner furnace 200 and the return structure 300, and the support members are connected to the inner side walls of the furnace body 100. In this way, the inner furnace 200 and the return structure 300 can be suspended in the furnace body 100 through the support members, so that the inner furnace 200 and the return structure 300 are wrapped in the water in the cavity, thereby increasing the heat conversion area with the water and improving the heat conversion efficiency.
[0033] like Figures 2 to 5 As shown, the inner furnace includes a first combustion chamber 210, a second combustion chamber 220, and a ash cleaning chamber 230. The interior of the first combustion chamber 210 defines a combustion chamber; the second combustion chamber 220 is disposed on one side of the first combustion chamber 210 and communicates with the combustion chamber; the ash cleaning chamber 230 is disposed on a side of the second combustion chamber 220 away from the first combustion chamber 210 and communicates with the second combustion chamber 220, wherein the first combustion chamber 210, the second combustion chamber 220, and the ash cleaning chamber 230 are all connected to multiple side walls of the furnace body 100 and communicate with the external space. In this way, there are multiple communication channels between the first combustion chamber 210, the second combustion chamber 220, the ash cleaning chamber 230 and the furnace body 100, so that the boiler can select and enable appropriate communication channels according to the installation environment, effectively improving the applicability of the boiler.
[0034] Optionally, a fire insulation layer 250 is provided between the second combustion chamber 220 and the ash cleaning chamber 230. In this way, the second combustion chamber 220 and the ash cleaning chamber 230 can be isolated by the fire insulation layer 250, so that the ash cleaning chamber 230 is prevented from being disturbed by the heat generated during the fuel combustion process of the second combustion chamber 220, and the stability of the working state of the ash cleaning chamber 230 is improved, thereby ensuring that the boiler can operate stably.
[0035] Optionally, a support structure is provided between the second combustion chamber 220 and the ash cleaning chamber 230. In this way, the second combustion chamber 220 and the ash cleaning chamber 230 are spaced apart, and the space between the two can be filled with water in the cavity, thereby reducing the interference of the ash cleaning chamber 230 with the heat generated during the fuel combustion process of the second combustion chamber 220, while increasing the heat conversion contact area between the second combustion chamber 220 and the water, thereby improving the heating efficiency of the water.
[0036] Optionally, the thermal insulation material includes but is not limited to cement fire insulation board and fire insulation brick.
[0037] like Figure 2 and Figure 4 As shown, a grate 260 is provided between the first combustion chamber 210 and the second combustion chamber 220. In this way, the fuel can be stacked in the second combustion chamber 220 through the grate 260 for combustion, and the flame and high-temperature flue gas generated by the combustion of the fuel can enter the first combustion chamber 210 through the grate 260, effectively improving the utilization efficiency of the fuel.
[0038] Optionally, a tubular structure with a through cavity is provided inside the grate 260, and is arranged in an interval arrangement between the first combustion chamber 210 and the second combustion chamber 220. In this way, the water in the cavity can flow in the through cavity inside the grate 260, so that the indirect contact area between the fuel and the water is increased during the combustion process, thereby improving the thermal conversion efficiency of the fuel.
[0039] like Figure 4 and Figure 5 As shown, at least two tempering tubes 240 are provided on the outer wall between the first combustion chamber 210 and the ash cleaning chamber 230, and one end of the tempering tube 240 is connected to the first combustion chamber 210, and the other end is connected to the ash cleaning chamber 230. In this way, the flame and high-temperature flue gas in the first combustion chamber 210 can enter the ash cleaning chamber 230 through the tempering tube 240, which not only increases the heat exchange area with water and improves the heat exchange efficiency, but also increases the combustion stroke, so that the fuel burns more fully and improves the fuel utilization rate.
[0040] Optionally, more than two tempering tubes 240 are provided on multiple outer side walls of the first combustion chamber 210 and the ash cleaning chamber 230. In this way, the flame and high-temperature flue gas in the first combustion chamber 210 can enter the ash cleaning chamber 230 from different directions through the tempering tubes 240 provided on different side walls of the first combustion chamber 210, thereby increasing the flow of the flame and high-temperature flue gas and improving the use efficiency of the fuel.
[0041] like Figure 6 and Figure 7As shown, the return structure 300 includes a first return section 310, a second return section 340, and a fire separation bag 330. A first fire collection bag 311 is provided at one end of the first return section 310, and the first fire collection bag 311 is connected to the ash cleaning chamber 230; the second return section 340 is arranged at one side of the first return section 310, and a second fire collection bag 341 is provided at one end; the fire separation bag 330 is connected to an end of the first return section 310 away from the first fire collection bag 311 and an end of the second return section 340 away from the second fire collection bag 341. In this way, the flame and high-temperature flue gas in the ash cleaning chamber 230 can enter the first return section 310, the fire separation bag 330 and the second return section 340 in sequence, which increases the heat conversion area of the flame and the high-temperature flue gas and improves the heat conversion efficiency. At the same time, while the flame and high-temperature flue gas flow in the first return section 310, the fire distribution bag 330 and the second return section 340, they can be sufficiently cooled, so that the smoke can be deposited in the first return section 310 and / or the fire distribution bag 330 and / or the second return section 340, effectively reducing the amount of smoke discharged.
[0042] Optionally, a plurality of fire tubes 320 are provided between the first fire collection package 311 and the fire distribution package 330. In this way, there are a plurality of connecting channels between the first fire collection package 311 and the fire distribution package 330, thereby improving the passing efficiency of the flame and high-temperature smoke, and also increasing the heat conversion contact area between the first fire collection package 311 and the fire distribution package 330, thereby improving the heat conversion efficiency.
[0043] Optionally, a plurality of fire tubes 320 are provided between the fire distribution package 330 and the second fire collection package 341, and the number of the fire tubes 320 is at least twice the number of the fire tubes 320 in the first return section 310. In this way, most of the flame and high-temperature flue gas entering the fire distribution package 330 from the first return section 310 enter the second fire collection package 341 from the upper fire tubes 320 in the second return section 340, and the flame and high-temperature flue gas entering the second fire collection package 341 flow back to the fire distribution package 330 from the lower fire tubes 320 in the second return section 340 under the action of the temperature difference, wherein the flame and high-temperature flue gas flowing back to the fire distribution package 330 partially remain in the fire distribution package 330, and partially flow back to the second fire collection package 341 following the flame and high-temperature flue gas newly entering the fire distribution package 330, and the cycle is repeated until the self-heat is consumed through heat conversion. This design not only improves the efficiency of fuel use, but also improves the heat conversion efficiency.
[0044] It can be understood that the fuel is accumulated on the surface of the grate 260 and burns through the second combustion chamber 220. The flame and high-temperature flue gas generated during the combustion of the fuel enter the first combustion chamber 210, the tempering tube 240, the cleaning chamber 230, the first return section 310, the fire distribution bag 330, and the second return section 340 in sequence from the second combustion chamber 220. While the fuel can be fully burned, the heat conversion journey of the flame and high-temperature flue gas is increased, effectively improving the heat conversion efficiency.
[0045] like Figure 6 and Figure 7 As shown, a cleaning pipe 350 is provided on the outer wall of the first fire collection package 311 and / or the second fire collection package 341, and one end of the cleaning pipe 350 is connected to the inner wall of the first fire collection package 311 and / or the second fire collection package 341, and the other end is connected to the outer wall of the furnace body 100. In this way, during the maintenance of the boiler, the staff can clean the dust deposited in the first fire collection package 311 and the second fire collection package 341 in time through the cleaning pipe 350, so as to avoid the accumulation of smoke and dust in the first fire collection package 311 and / or the second fire collection package 341 affecting the operation of the boiler, and effectively improve the stability of the boiler operation.
[0046] Optionally, a plurality of side walls of the first fire collection package 311 and / or the second fire collection package 341 are provided with ash cleaning pipes 350. In this way, appropriate ash cleaning pipes 350 can be selected and activated to perform corresponding ash cleaning work according to the installation environment and position of the boiler, thereby improving the overall applicability of the boiler.
[0047] Optionally, the ash cleaning pipe 350 can be used to install a smoke exhaust pipe. In this way, the smoke exhaust pipe can be selectively installed according to actual installation conditions and work requirements, so as to further improve the working efficiency of the boiler.
[0048] Optionally, a detachable closing cap 351 is provided on one side of the ash cleaning pipe 350 facing the outer wall of the furnace body 100. In this way, during the operation of the boiler or when the ash cleaning pipe 350 is not activated, the ash cleaning pipe 350 can be blocked by the closing cap so that the furnace body 100 remains closed, effectively preventing foreign matter from entering or other unexpected safety accidents.
[0049] Optionally, a fireproof material is provided on the side of the sealing cap facing the first fire collection package 311 and / or the second fire collection package 341. In this way, the fireproof material effectively isolates the temperature of the flame and high-temperature smoke in the first fire collection package 311 and / or the second fire collection package 341, reduces the temperature of the side of the sealing cap away from the first fire collection package 311 and / or the second fire collection package 341, and reduces the possibility of accidental burns.
[0050] like Figures 8 to 9 As shown, the furnace body 100 further includes a closed door 110 , which is disposed on the outer side wall of the furnace body 100 and is adapted to the first combustion chamber 210 , the second combustion chamber 220 , and the ash cleaning chamber 230 .
[0051] Optionally, the closed door 110 is rotatably arranged on the side wall of the furnace body 100, and a fireproof material is arranged on the side of the closed door 110 facing the first combustion chamber 210, the second combustion chamber 220 or the ash cleaning chamber 230. In this way, the closed door 110 is effectively isolated from the temperature of the combustion chamber side by the fireproof material.
[0052] It can be understood that when the boiler is in working state, the closure adapted to the first combustion chamber 210 is in an open state, while the second combustion chamber 220 and the cleaning chamber 230 are adapted so that the closure door 110 is in a closed state, so that the fuel in the first combustion chamber 210 can obtain sufficient oxygen during combustion.
[0053] like Figure 8 and Fig. 9 As shown, the furnace body 100 also includes a heating water outlet pipe 120, a heating water return pipe 121, a water supply water inlet pipe 130, a water supply water outlet pipe 131, a water level gauge 140, a closed door 160, and a sewage outlet 170. The closed door 160 is arranged on one side of the furnace body 100 and is adapted to the fire distribution package 330; the heating water outlet pipe 120 and the heating water return pipe 121 are arranged on multiple side walls of the furnace body 100; the water supply water inlet pipe 130 and the water supply water outlet pipe 131 are also arranged on multiple side walls of the furnace body 100; the water level gauge 140 is arranged on one side of the heating water outlet pipe 120; the sewage outlet is arranged on one side of the heating water return pipe 121 and is connected to the cavity.
[0054] Optionally, the water supply inlet pipe 130 is connected to one end of the metal hose 400, and the water supply outlet pipe 131 is connected to the other end of the metal hose, and the water supply inlet pipe 130 and the water supply outlet pipe 131 can be arranged on different outer side walls of the furnace body 100. In this way, when the boiler is installed, the water supply inlet pipe 130 and the water supply outlet pipe 131 on different side walls can be selected and activated according to the installation position, thereby improving the applicability of the boiler.
[0055] Optionally, a reserved mounting seat 132 connected to the metal hose 400 is provided on the side wall of the furnace body 100 for installing the water supply inlet pipe 130 and the water supply outlet pipe 131, and a plug is provided in the reserved mounting seat 132. In this way, the water supply inlet pipe 130 at different positions can be activated or deactivated at any time through the reserved mounting seat 132, and the reserved mounting seat 132 is blocked by the plug when not activated, thereby preventing leakage of the reserved mounting seat 132 when not activated.
[0056] Optionally, a top water inlet pipe 150 and a top water outlet pipe 151 for water supply are further provided on the top of the furnace body 100 , both of which are connected to the metal hose 400 .
[0057] It can be understood that the water supply inlet pipe 130 and / or the top water supply inlet pipe 150 are connected to the external water network, so that the cold water in the water network enters the metal hose 400 through the water supply inlet pipe 130 and / or the top water supply inlet pipe 150, and the cold water is gradually heated during the flow in the metal hose, and is finally discharged from the water supply outlet pipe 131 and / or the top water supply outlet pipe 151.
[0058] Optionally, the sealed door 160 is arranged on the furnace body 100 in a rotating and closed manner. In this way, during the operation of the boiler, the sealed door 160 is closed to prevent the flame and high-temperature flue gas in the fire-distributing bag 330 from leaking. When the boiler is under maintenance, the inside of the fire-distributing bag 330 and the fire tube 320 can be cleaned by opening the sealed door 160 to prevent dust from accumulating in the fire-distributing bag 330 and the fire tube 320, thereby improving the stability of the boiler operation.
[0059] like Fig.10 As shown, a detachable flange connection seat 500 is provided on the outer side wall of the furnace body 100. In this way, the boiler can be connected with other equipment through the detachable flange connection seat 500 according to actual needs, thereby effectively improving the applicability of the boiler.
[0060] Optionally, the flange connection seat 500 is arranged at the edge of the second combustion chamber 220 .
[0061] Optionally, a burner is also included, and its fire output end is adapted to be connected with the flange connection seat 500. In this way, after the burner is connected with the boiler through the flange, gas is used as the fuel supply for the boiler operation, thereby improving the diversity of the boiler's fuel selection.
[0062] Optionally, a biomass feeding device is further included, and the feeding port included in the biomass feeding device is adapted to be connected with the flange connection seat 500. In this way, after the biomass feeding device is connected to the boiler through the flange, biomass is used as the fuel supply for the boiler operation, which improves the diversity of the boiler's fuel selection.
[0063] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
