Description

Technical Field

[0001] This utility model relates to the field of charcoal slag treatment technology, specifically to a flame nozzle structure for a charcoal slag furnace. Background Technology

[0002] When burning charcoal slag, the charcoal slag furnace usually uses a flame nozzle to inject gas into the furnace tube, which is then ignited electronically. However, the existing flame nozzles have the following problems when in use: (1) The flame nozzle only has dense gas outlet holes at the end with a diameter of 57mm. The gas supply is unstable, and the flame will go out intermittently; (2) After ignition, the flame only burns in the center, which results in slow heating in the furnace. Only one batch of electrolyte can be produced every 8 hours. This is not only inefficient, but also consumes a lot of natural gas, which increases production costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a flame nozzle structure for a charcoal slag furnace, which avoids intermittent flame extinguishing, while increasing the flame size, accelerating the temperature rise, reducing the electrolyte consumption time per furnace, and improving work efficiency, thus effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flame nozzle structure for a charcoal slag furnace, comprising a jet pipe and a gas pipe, wherein the jet pipe and the gas pipe are welded in a vertical direction, the end of the jet pipe is provided with a plurality of end jet holes, the outer side of the jet pipe is provided with side jet holes, and the outer side of the jet pipe is provided with a guide plate, the guide plate being located on one side of the side jet holes.

[0005] As a preferred embodiment of this utility model, the diameter of both the side jet hole and the end jet hole is 105mm.

[0006] As a preferred embodiment of this utility model, the number of end jet holes is five, the number of side jet holes is arranged in a circle along the central axis of the jet pipe, and the number of side jet holes in each circle is ten. Three circles of side jet holes are arranged at equal intervals on the outer side of the jet pipe.

[0007] As a preferred embodiment of this invention, at least two auxiliary side jet holes are provided between each adjacent side jet hole.

[0008] As a preferred embodiment of this utility model, the number of guide plates is ten, and the ten guide plates are evenly distributed in a spiral shape on the outer side of the jet pipe.

[0009] As a preferred embodiment of this utility model, the guide plate is fitted with the inner wall of the furnace tube of the charcoal slag furnace.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) an end jet hole and a side jet hole are respectively provided at the end and the outside of the jet pipe, and the diameter of the end jet hole and the side jet hole is increased, so that the amount of gas ejected increases and the intermittent flame extinguishing is avoided; (2) by setting a spiral guide plate on the outside of the jet pipe, the diffusion direction of the gas can be restricted, so that the flame maintains a specific length and width, and diffuses from the center position to the outside in the pipe to form a flame ball, while forming a vortex, so that the ejected gas and the flame are fully mixed, improving the combustion speed and completeness, thereby improving the temperature rise rate and accelerating the finished product efficiency of the electrolyte.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a flame nozzle structure for a charcoal slag furnace, including a jet pipe 1 and a gas pipe 2, which are welded vertically. A certain proportion of natural gas and oxygen are introduced into the gas pipe 2. Five end jet holes 3 are provided at the end of the jet pipe 1, and side jet holes 4 are provided on the outer side of the jet pipe 1. The side jet holes 4 are arranged in a circle along the central axis of the jet pipe 1, with ten side jet holes 4 in each circle. Three circles of side jet holes 4 are arranged at equal intervals on the outer side of the jet pipe 1. By increasing the side jet holes 4, the contact area between the gas and the flame can be increased, improving the combustion performance. Furthermore, the diameter of both the side jet holes 4 and the end jet holes 3 is set to 105mm, which increases the gas output compared to the original diameter, thus avoiding intermittent flameout.

[0017] A guide plate 5 is provided on the outer side of the jet pipe 1. The guide plate 5 is located on one side of the side jet hole 4. By setting the guide plate 5, the gas can be guided to diffuse along its length direction, so that the flame maintains a specific length and angle and diffuses from the center to the outside, changing the original linear flame into a ball flame, so that the furnace can be heated quickly and the gas can be burned more completely.

[0018] To further improve combustion efficiency, at least two auxiliary side jet holes 6 are provided between each adjacent side jet hole 4, and the diameter of the auxiliary side jet hole 6 is 35mm.

[0019] Furthermore, in order to improve the combustion speed, there are ten guide vanes 5. The ten guide vanes 5 are evenly distributed in a spiral shape on the outer side of the jet pipe 1. Through the design of the spiral guide vanes 5, the gas enters the flame in a tangential direction, forming a vortex, so that the gas can be fully combusted.

[0020] In order to facilitate the stable placement of the jet pipe 1 inside the furnace tube of the charcoal slag furnace and ensure combustion stability, the guide plate 5 is fitted with the inner wall of the furnace tube of the charcoal slag furnace.

[0021] In use: Place the jet pipe 1 inside the furnace tube of the charcoal slag furnace. The guide plate 5 on the outside of the jet pipe 1 is in contact with the inner wall of the furnace tube to ensure the stability of the nozzle structure. After oxygen and natural gas are filled into the gas pipe 2 in a certain proportion, they are sprayed out through the jet pipe 1. Under the action of the ignition device, the flame is sprayed out. Under the action of the guide plate 5, the flame spreads evenly from the center to the outside to form a flame ball, which burns the charcoal slag.

[0022] After use, this invention can generate one batch of finished electrolyte every 6 hours, which is one more batch of electrolyte per day than before, while saving gas and reducing production costs.

[0023] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model.
