Description

Technical Field

[0001] This utility model relates to the field of fecal treatment technology, and in particular to an ammonia reprocessing device for heating solid particles after ammonia removal from feces. Background Technology

[0002] Human excrement is mainly composed of organic matter. During the degradation process, human excrement produces ammonia, which is highly toxic and affects human health. It can also damage plants and animals, disrupting the ecological balance. In addition, ammonia reacts chemically with other substances in the atmosphere to form secondary pollutants, further aggravating environmental pollution. Therefore, ammonia must be rendered harmless before it can be released. Utility Model Content

[0003] The purpose of this invention is to provide an ammonia reprocessing device for heating solid particles after ammonia removal from feces, in order to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An ammonia reprocessing device for heating solid particles after ammonia removal from feces includes an electromagnetic induction furnace, which includes an electromagnetic induction coil and a furnace body for holding materials.

[0006] The furnace body is a vertically placed, non-magnetic steel furnace body. A material inlet for supplying materials is provided at the bottom of the furnace body, a waste discharge outlet is provided at the top of the furnace body, and a gas supply outlet for supplying combustion-supporting gas is also provided in the furnace body.

[0007] It also includes an auger system, which consists of an electric drive system and an auger.

[0008] The electric drive system is located outside the furnace body, and the spiral body is vertically installed inside the furnace body. The spiral body is made of soft magnetic steel and has water outlets arranged from top to bottom. The average distance from the outer edge of the spiral body to the electromagnetic induction coil at the same height is less than 2cm.

[0009] By adopting the above technical solution, the furnace body is made of 304 stainless steel. 304 stainless steel has a maximum heat resistance temperature of 800 degrees Celsius and excellent corrosion resistance. Human feces with a moisture content of 60% can be burned at only about 600 degrees Celsius. The auger system relies on the rotation of the spiral to transport the feces from the bottom to the top of the furnace body. In this process, solid-liquid separation is completed, which reduces the moisture content of the feces and saves the energy required for ignition. The alternating magnetic field generated by the electromagnetic induction coil generates eddy currents on the spiral made of soft magnetic steel, which rapidly increases the temperature of the spiral and causes the feces to start burning. The oxygen released from the combustion gas supply port burns and reacts with the ammonia in the feces to generate nitrogen gas that is harmless to the human body.

[0010] In a further embodiment, the pitch between the spirals ranges from 160mm to 200mm, and the pitch between the spirals gradually decreases from bottom to top.

[0011] By adopting the above technical solution, the pitch of the spiral is not fixed. At the bottom, because it is necessary to transport larger pieces of feces, the pitch of the spiral is 200mm. As the feces burn, the spiral shortens to 160mm, which helps the fecal residue after combustion to be discharged from the discharge port.

[0012] In a further embodiment, the width of the helix is ​​less than 350 mm, and the thickness of the helix ranges from 3 mm to 3.5 mm.

[0013] By adopting the above technical solution, since feces are relatively viscous, a wider spiral can improve the conveying efficiency and reduce blockage.

[0014] In a further embodiment, the helical body is made of silicon alloy steel.

[0015] By adopting the above technical solution, silicon alloy steel has the characteristics of high magnetic permeability, low coercivity and large resistivity. The furnace body is heated by electromagnetic induction coil. Therefore, the higher the magnetic permeability, the faster the spiral body is heated, and the more quickly it can be heated to the ignition temperature of the feces.

[0016] In a further embodiment, the inner wall of the furnace body is lined with ceramic heat storage material.

[0017] In a further embodiment, the surface of the ceramic heat storage body is uniformly distributed with a honeycomb structure.

[0018] By adopting the above technical solution, during the combustion process, the ammonia-oxygen gas needs to maintain a high temperature during the continuous combustion of feces. Sometimes, the temperature will exceed the temperature required to ignite the feces. The honeycomb ceramic heat storage body can store heat during the combustion of feces, retain a large amount of heat, and release heat when the temperature in the furnace begins to drop, ensuring that the temperature in the furnace does not drop below the ignition temperature of the feces, thereby improving the efficiency of feces combustion, stabilizing the combustion temperature, and thus achieving a more stable and efficient combustion process.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By setting up an electromagnetic induction coil and a spiral, the electromagnetic induction coil can work with the spiral to generate heat, and the rotation of the spiral can carry the solids in the feces out of the solid-liquid mixture at the bottom of the furnace, leaving only the more easily combustible solids to rise with the spiral, reducing the difficulty of igniting the feces, thereby achieving a higher combustion efficiency.

[0021] 2. By using silicon alloy steel, the high magnetic permeability of silicon alloy steel allows the electromagnetic induction furnace to directly heat the spiral itself using the electromagnetic induction coil. Therefore, the higher the magnetic permeability of the spiral, the faster the spiral heats up, which can achieve the effect of heating the feces to the ignition temperature more quickly.

[0022] 3. By setting up a ceramic heat storage body, excess heat released during the combustion of feces can be stored, preserving more heat. When the temperature inside the furnace begins to drop, the ceramic heat storage body releases heat to ensure that the temperature inside the furnace does not drop below the ignition temperature of the feces, thereby stabilizing the combustion temperature and making the feces combustion process more stable and efficient.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the attached figures. Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this specification, "a plurality of" means two or more, unless otherwise explicitly and specifically defined by the direction of the center.

[0027] like Figure 1 As shown, the ammonia reprocessing device for heating solid particles after ammonia removal from feces includes an electromagnetic induction furnace 1, which includes an electromagnetic induction coil 11 and a furnace body 12 for holding materials.

[0028] The furnace body 12 is a vertically placed non-magnetic steel furnace body 12. The bottom of the furnace body 12 is provided with a material inlet for supplying materials, and the top of the furnace body 12 is provided with a waste discharge outlet. The furnace body 12 is also provided with a gas supply outlet for supplying combustion-supporting gas.

[0029] It also includes a screw conveyor system 2, which includes an electric drive system 21 and a screw 22;

[0030] The electric drive system 21 is set outside the furnace body 12, and the spiral body 22 is set vertically inside the furnace body 12. The spiral body 22 is made of soft magnetic steel. The spiral body 22 has water outlets arranged from top to bottom. The average distance from the outer edge of the spiral body 22 to the electromagnetic induction coil 11 at the same height is less than 2cm.

[0031] In this embodiment, the electromagnetic induction furnace 1 uses electromagnetic induction heating. The electromagnetic induction coil 11 rapidly heats the spiral body 22 made of soft magnetic steel, causing the spiral body 22 to heat up and ignite the feces. The spiral body 22 rotates under the control of the electric drive system 21 and initially separates the solid and liquid in the feces. When the temperature of the spiral body 22 reaches the ignition point of the feces, the oxygen in the furnace body 12 reacts with the ammonia in the feces, thereby decomposing the ammonia. The auger system 2 can reduce the difficulty of igniting the feces, save energy, and make the combustion efficiency of the feces higher.

[0032] Furthermore, the material of the spiral body 22 is silicon alloy steel, the pitch between the spiral bodies 22 ranges from 160mm to 200mm, the pitch between the spiral bodies 22 gradually decreases from bottom to top, the width of the spiral body 22 is less than 350mm, and the thickness of the spiral body 22 ranges from 3mm to 3.5mm.

[0033] In this embodiment, the silicon alloy steel spiral 22 has good magnetic permeability, and higher magnetic permeability means that it heats up faster with the same energy consumption. The larger pitch at the bottom of the spiral 22 is because it is used to transport large pieces of feces, while the pitch of the spiral 22 gradually decreases from bottom to top because the volume of feces decreases accordingly after combustion. Therefore, a smaller pitch is needed to ensure that the residue after the feces are burned can be discharged from the discharge port. Since the transported feces are relatively viscous, the required spiral 22 width is wider. At the same time, since the weight per unit volume of feces is relatively light, the spiral 22 thickness is thinner.

[0034] Furthermore, the inner wall of the furnace body 12 is covered with a ceramic heat storage body 3, and the surface of the ceramic heat storage body 3 is uniformly distributed with a honeycomb structure.

[0035] In this embodiment, the furnace body 12 is made of 304 stainless steel, which has ordinary heat insulation performance. However, by laying honeycomb ceramic heat storage body 3 on the inner wall of the furnace body 12, the excellent heat storage performance of the honeycomb ceramic heat storage body 3 can be relied upon to absorb excess heat into the interior of the honeycomb ceramic heat storage body 3 during the process of successful ignition and the start of combustion of feces. When the combustion of feces ends and new feces are reintroduced into the furnace body 12, the honeycomb ceramic heat storage body 3 releases its internal heat storage, so that the temperature inside the furnace body 12 can reach the ignition temperature of feces again. This makes the entire combustion process more stable and efficient.

[0036] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0037] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
