The structure is simple and convenient for assembly, convenient for production and processing, and has a lower cost;

[0005] However, for the devices proposed in the above two patent documents, although they can facilitate most of the mixed gas in the gas storage chamber to be sprayed into the combustion chamber, and divert the remaining part of the mixed gas into the combustion chamber to assist in burning the gas directly injected into the central area, in actual use, due to the relatively fast direct injection flow rate of most of the mixed gas in the central area, at high altitude locations such as plateaus, the oxygen content is relatively low when the mixed gas is directly injected, and it is prone to extinguish when ignited, so the scope of application has limitations. Summary of the Utility Model

[0006] The present utility model provides an air outlet assembly for a direct-injection gasifier dedicated for high altitudes, which solves the problem in related technologies that at high-altitude locations such as plateaus, when the mixed gas is directly injected, the oxygen content is relatively low and it is easy to fail to ignite.

[0007] The technical solution of the present utility model is as follows: It includes a ceramic cup and a retaining ring. Inside the ceramic cup, there is a base, and an input pipe communicating with the bottom surface of the base. Inside the base, there is a flange, and a flow-dividing column connected to the flange and located inside the base. The flow-dividing column is used to diffuse the gas to the periphery; a direct-injection hole communicating with each other is opened in the flange and the flow-dividing column, and the direct-injection hole is used for directly injecting the gas. An auxiliary punching hole is opened on the upper surface of the flange, and the auxiliary punching hole is used to eject part of the gas diffused to the periphery upward.

[0008] Preferably, the input pipe penetrates through a reserved hole on the bottom surface of the ceramic cup and extends to the lower part of the ceramic cup. The input pipe is used for inputting or outputting gas. By setting the input pipe, it can be connected to an external gas supply device, so that the mixed gas transmitted by the gas supply device can be transmitted to the inside of the base through the input pipe.

[0009] Preferably, the upper surface of the retaining ring is fixedly connected to the bottom surface of the flow-dividing column, and several ventilation grooves inside the flow-dividing column diffuse the gas to the periphery of the flow-dividing column through the retaining ring. By setting the flow-dividing column, it is not only convenient for transmitting the mixed gas, but also can block a little mixed gas during the transmission process.

[0010] Preferably, several inclined grooves inside the flow-dividing column are all inclined from the center to both sides, and the inner inclined grooves communicate with the auxiliary punching holes. By setting the inclined grooves inside the flow-dividing column, it is convenient for re-transmitting the diffused mixed gas, and can transmit the diffused gas into the auxiliary punching holes, and slowly eject it through the auxiliary punching holes, so as to play an auxiliary ignition effect on the directly injected gas.

[0011] Preferably, the length value of the flow-dividing column is greater than the length value of the inner cavity of the base. The space between the flow-dividing column and the base is used for discharging the diffused gas. By setting the flow-dividing column higher than the base, it is convenient to diffuse the diffused mixed gas into the inside of the ceramic cup, further enhancing the auxiliary ignition effect on the directly injected gas.

[0012] Preferably, several inclined plates are arranged in the several inclined grooves inside the flow-dividing column. The inclined plates are used for batch-transmitting the diffused gas to the outside of the auxiliary punching holes and the flow-dividing column. By setting the inclined plates, it is convenient to re-divert the diffused mixed gas, so that most of the diffused mixed gas can be transmitted into the auxiliary punching holes and discharged to assist in burning the directly injected gas.

[0013] Preferably, a nozzle is provided on the inner wall of the direct impact hole. The nozzle is used to enhance the flow rate of the gas during gas transmission in the direct impact hole. By setting the nozzle, the flow rate of the mixed gas in the direct impact hole can be better increased, so as to facilitate avoiding the situation of extinguishing after ignition.

[0014] The working principle and beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the input pipe is connected to an external gas supply device to transmit the mixed gas into the base. A relatively large part of the mixed gas is ejected through the direct impact hole, while the remaining mixed gas is blocked by the shunt column, resulting in a decrease in gas flow rate and diffusion. During diffusion, the remaining mixed gas is shunted again, so that a relatively large part of the remaining mixed gas is slowly ejected through the auxiliary punching holes, thereby being able to assist in burning the mixed gas directly ejected through the direct impact hole and being able to be fully mixed with oxygen and ignited at a high altitude or a location with a high elevation.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 to 5 shown, this embodiment proposes an air outlet assembly of a direct gasification furnace dedicated for high altitudes, including a ceramic cup 1 and a retaining ring 4. Inside the ceramic cup 1, there is a base 2 and an input pipe 3 connected to the bottom surface of the base 2. Inside the base 2, there is a flange 5 and a flow dividing column 6 connected to the flange 5 and located inside the base 2. The flow dividing column 6 is used to diffuse the gas to the periphery.

[0026] In this embodiment, referring to Figures 1 through 5 , the setting of the ceramic cup 1 is for the combustion of the mixed gas inside the ceramic cup 1, and the setting of the base 2 facilitates the transmission of the mixed gas. And through the flange 5 and the flow dividing column 6, the mixed gas is transmitted and divided, so that it is convenient to ignite the mixed gas with an external ignition component. The diffused mixed gas can facilitate the combustion support of the mixed gas during direct impact.

[0027] The input pipe 3 penetrates through a reserved hole on the bottom surface of the ceramic cup 1 and extends to the lower part of the ceramic cup 1. The input pipe 3 is used for the input or output of gas. By setting the input pipe 3, it can be connected to an external gas supply device, so that the mixed gas transmitted by the gas supply device can be transmitted to the inside of the base 2 through the input pipe 3, and then ignited through the cooperation of the base 2 and the device components.

[0028] The upper surface of the retaining ring 4 is fixedly connected to the bottom surface of the flow dividing column 6, and several ventilation grooves in the flow dividing column 6 diffuse the gas to the periphery of the flow dividing column 6 through the retaining ring 4. By setting the flow dividing column 6, it is not only convenient to transmit the mixed gas, but also can block a little mixed gas during the transmission process, so that the blocked mixed gas is transmitted to the outside of the flow dividing column 6, which is convenient for the use of auxiliary ignition.

[0029] The length value of the flow dividing column 6 is greater than the length value of the inner cavity of the base 2. The space between the flow dividing column 6 and the base 2 is used for the discharge of the diffused gas. By setting the flow dividing column 6 higher than the base 2, it is convenient to diffuse the diffused mixed gas into the ceramic cup 1, further improving the effect of assisting in igniting the direct impact gas, greatly enhancing the practicality of the overall device, and being able to achieve the ignition effect in high altitude or high altitude and low oxygen content environments.

[0030] Embodiment 2

[0031] As Figures 1 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that: there are directly connected impact holes 7 opened in the flange 5 and the flow dividing column 6, and the directly connected impact holes 7 are used for the direct impact of gas. The upper surface of the flange 5 is provided with auxiliary punching holes 8, and the auxiliary punching holes 8 are used for spraying some of the gas diffused to the periphery upward.

[0032] In this embodiment, referring to Figures 1 through 5, the straight-through hole 7 is provided to enable the mixed gas to directly rush into the ceramic cup 1 through the straight-through hole 7. And through the provision of the auxiliary punching holes 8, it is possible to facilitate the slow spraying of the diffused mixed gas around the straight-through mixed gas, so as to be able to fully blend with the oxygen in the plateau or at a higher altitude, improve the success rate of ignition, and avoid the situation of ignition failure caused by poor contact between the mixed gas and oxygen during straight-through.

[0033] A number of inclined grooves in the flow dividing column 6 are inclined from the center to both sides, and the inner inclined grooves communicate with the auxiliary punching holes 8. Through the provision of the inclined grooves in the flow dividing column 6, it is possible to facilitate the retransmission of the diffused mixed gas and transmit the diffused gas into the auxiliary punching holes 8 for slow ejection through the auxiliary punching holes 8, thereby facilitating the cooperation with the mixed gas directly rushed through the straight-through hole 7. The mixed gas with a slower flow rate can improve the contact between the directly rushed gas and oxygen, thus having an auxiliary ignition effect on the directly rushed gas.

[0034] A number of inclined grooves in the flow dividing column 6 are provided with flow dividing inclined plates 9. The flow dividing inclined plates 9 are used to batch-transmit the diffused gas to the outside of the auxiliary punching holes 8 and the flow dividing column 6. By providing the flow dividing inclined plates 9, it is possible to facilitate the re-shunting of the diffused mixed gas, so that most of the diffused mixed gas can be transmitted into the auxiliary punching holes 8 for exhausting to assist in burning the directly rushed gas, while a small amount of diffused mixed gas will diffuse into the interior of the ceramic cup 1, thus being able to play a role in assisting combustion after ignition, greatly improving the practicality and convenience of the overall device.

[0035] The inner wall of the straight-through hole 7 is provided with a spray pipe 10. The spray pipe 10 is used to enhance the flow rate of the gas during transmission in the straight-through hole 7. By providing the spray pipe 10, it is possible to better improve the flow rate of the mixed gas in the straight-through hole 7, so as to be able to avoid the situation of extinguishing after ignition, thus greatly improving the practicality and application range of the overall device.

[0036] Working principle: By installing the base 2 into the ceramic cup 1, connecting the input pipe 3 with an external gas outlet component and a gas supply control mechanism, transmitting the mixed gas into the base 2 through the input pipe 3, a relatively large part of the mixed gas is ejected through the straight-through hole 7, while the remaining mixed gas is diffusely transmitted to the periphery of the flow dividing column 6 through the inclined grooves at the flow dividing column 6. The gas flow rate is reduced due to the obstruction of the flow dividing column 6, and while diffusing, the remaining mixed gas is shunted again, so that a relatively large part of the remaining mixed gas is slowly ejected through the auxiliary punching holes 8, thereby being able to assist in burning the mixed gas directly sprayed through the straight-through hole 7, being able to fully mix with oxygen at a plateau or a higher altitude, and then being convenient for combustion by an ignition component. And a relatively small part of the remaining mixed gas can also flow into the inner cavity of the base 2 to assist in burning during direct combustion.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
