Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a reflux device for a tar burner. Background Technique

[0002] A burner is a general term for a device that sprays and mixes fuel and air for combustion. Burners are classified into industrial burners, combustion machines, domestic burners, and special burners according to types and application fields. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or metal titanium. The function of a burner is to atomize the sample through flame combustion. The atomized test solution enters the burner, and under the action of the flame temperature and flame atmosphere, through processes such as drying, melting, evaporation, and dissociation, a large number of ground-state atoms, as well as some excited-state atoms, ions, and molecules are generated. A well-designed burner should have the performance of high atomization efficiency, low noise, and stable flame to ensure high absorption sensitivity and measurement precision. In atomic absorption spectrometry, a slit burner is commonly used to generate atomic vapor. According to the types of fuel gas and combustion-supporting gas used, the length and width of the burner slit are different. Generally, the applicable fuel gas and combustion-supporting gas are marked on the burner.

[0003] The application number is CN201721530452.6, which discloses a reflux burner, belonging to the field of pulverized coal burners. The key lies in: including a primary air duct, a secondary air duct, a fuel gun, and an ignition gun. The nozzle of the primary air duct is located inside the secondary air duct. The feature is that: the fuel gun is located in the primary air duct and extends from the nozzle of the primary air duct into the secondary air duct, and the nozzle of this fuel gun is located inside the secondary air duct; the nozzle of the ignition gun is also located inside the secondary air duct and is close to the nozzle of the fuel gun; the reflux burner also includes an annular baffle, the annular baffle is fixedly sleeved on the outer wall of the fuel gun, and the outer diameter of the annular baffle is larger than the inner diameter of the primary air duct and smaller than the inner diameter of the secondary air duct. The utility model can directly reduce the flow rate of pulverized coal in the primary air and will not cause the phenomenon of pulverized coal blockage, achieving the effects of controlling the flame length and making the pulverized coal burn more fully in the burner.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in 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 of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figure 1 - Figure 4As shown in the figure, the utility model is a reflux device for a tar burner, including a burner assembly 1. A convection furnace tube assembly 2 is installed inside the burner assembly 1. A rotating assembly 3 is installed at the front bottom of the convection furnace tube assembly 2, and an auxiliary rotating assembly 4 is installed at the rear bottom thereof.

[0026] By installing the rotating assembly 3 on the device, it can provide a certain degree of flexibility in adjustment during the internal processing work, especially for heating and reflux work, thus avoiding the situation of low traditional processing efficiency during use.

[0027] The burner assembly 1 includes a feeding port 101. A radiation chamber 102 is installed at the bottom of the feeding port 101. A connection port 103 is installed on the inner wall of the radiation chamber 102, and an installation bottom plate 104 is installed at its bottom. An installation wall 105 is installed at the top end of the installation bottom plate 104. It enters the radiation chamber 102 through the feeding port 101 and burns. The high-temperature flue gas generated by the combustion serves as a heat carrier and flows to the convection furnace body 201 through the connection port 103.

[0028] The convection furnace tube assembly 2 includes a convection furnace body 201 and a heat-conducting inner wall 205. A positioning ring 202 is installed on the front outer wall of the convection furnace body 201, and a limiting ring 203 is installed on the rear outer wall thereof. At the same time, one side is installed on the inner wall of the connection port 103, and the other side is installed on the inner wall of the installation wall 105. The heat-conducting inner wall 205 is installed on the inner wall of the convection furnace body 201, and a reflux assembly 204 is correspondingly installed inside it. Heat is obtained from the flue gas flowing through the convection furnace body 201 by convection. These heats are then conducted from the outer surface of the convection furnace body 201 to the heat-conducting inner wall 205 by heat transfer, and at the same time, are transferred to the crude oil or other fluids flowing inside it by convection. At the same time, in the radiation chamber 102, the flame ejected by the burner assembly 1 radiates heat to the outer surface of the convection furnace body 201 and the furnace wall where the convection furnace body 201 is laid. The combined action of these two parts of radiant heat causes the outer surface of the convection furnace body 201 to heat up and form a temperature difference with the inner surface of the pipe wall. Heat flows to the heat-conducting inner wall 205 by conduction, and the fluid flowing inside the pipe continuously obtains heat from the inner wall of the pipe, realizing the technological requirements for heating the fluid.

[0029] The rotating assembly 3 includes a rotating motor 301. A rotating gear 302 is installed at the front end of the rotating motor 301. An outer wall gear 303 is installed on one side of the rotating gear 302. The outer wall gear 303 is installed on the outer wall of the convection furnace body 201 and inside the positioning ring 202. By the rotation of the rotating motor 301, the rotating gear 302 at the end is driven, and then the outer wall gear 303 adjacent to one side is driven by the rotating gear 302, so that the outer wall gear 303 drives the rotation of the convection furnace body 201, which provides good assistance for the heating or reflux of the fluid inside it.

[0030] The auxiliary rotation assembly 4 includes a bracket 401. A limiting cavity 402 is formed inside the bracket 401, and a mounting rod 403 is installed on one side of the inner wall. A rotating roller 404 is installed on the outer side of the mounting rod 403. When braking and rotating at the front side, the rotating roller 404 inside the bracket 401 installed at the rear side drives the convection furnace body 201 installed inside it to rotate in the same direction through the rotating roller 404, thus avoiding the situation of jamming during rotation and ensuring its smooth working effect.

[0031] The reflux assembly 204 includes a connecting rod 2041. The connecting rod 2041 is installed at the middle position of the mounting wall 105, and a spiral blade 2042 is installed on its outer side.

[0032] When using this device, first, the fuel is pre-treated to remove or reduce the tar content therein. The treated fuel enters the burner assembly 1, enters the radiation chamber 102 through the feeding port 101, and burns. The high-temperature flue gas generated by the combustion serves as a heat carrier and flows to the convection furnace body 201 through the connection port 103, and then obtains heat from the flue gas flowing through the convection furnace body 201 by convection. These heats are then conducted from the outer surface of the convection furnace body 201 to the heat-conducting inner wall 205 by heat transfer, and are simultaneously transferred to the crude oil or other fluids flowing inside it by convection. At the same time, in the radiation chamber 102, the flame ejected by the burner assembly 1 radiates heat to the outer surface of the convection furnace body 201 and the furnace wall where the convection furnace body 201 is laid by radiation. The combined action of these two parts of radiant heat causes the outer surface of the convection furnace body 201 to heat up and form a temperature difference with the inner surface of the pipe wall. Heat flows to the heat-conducting inner wall 205 by conduction, and the fluid flowing in the pipe continuously obtains heat from the inner wall of the pipe, realizing the technological requirement of heating the fluid. When it is performing convection and reflux and other operations, with the help of the rotating assembly 3 and the auxiliary rotation assembly 4, its efficiency can be increased. The rotation of the rotating motor 301 drives the rotating gear 302 at the end, and then the rotating gear 302 drives the outer wall gear 303 adjacent to one side, thereby enabling the outer wall gear 303 to drive the rotation of the convection furnace body 201, which provides good assistance for heating or refluxing the fluid inside it. And under the rotation of the rotating assembly 3, the auxiliary rotation assembly 4 will also work together. When braking and rotating at the front side, the rotating roller 404 inside the bracket 401 installed at the rear side drives the convection furnace body 201 installed inside it to rotate in the same direction through the rotating roller 404, thus avoiding the situation of jamming during rotation and ensuring its smooth working effect.
