Description

Technical Field

[0001] The present invention belongs to the field of catalytic degradation of industrial sewage by materials, and particularly relates to an intelligent device for solid-liquid separation and waste gas collection of wastewater catalyzed by amorphous alloys. Background Art

[0002] Amorphous alloy is a new type of metastable metal material with accumulated atomic disorder obtained by ultra-rapid solidification of alloy melt. In addition to having unique physical and mechanical properties, amorphous alloy has high catalytic efficiency, low metal leaching and excellent recyclability in sewage treatment, and has broad prospects in the field of industrial wastewater treatment.

[0003] The Chinese invention patent with the application number 201811352972.1 discloses a method for preparing iron-based amorphous alloy powder for degrading dye wastewater, and discloses the application of the ultrasonic-treated iron-based amorphous alloy powder in degrading dye waste liquid. However, hydrogen peroxide etc. are needed during the reaction process, and insoluble substances such as Fe(OH)3 will be generated during the reaction process. In addition, the application number 201811638068.7 mentions that when amorphous alloy is used to treat heavy metal industrial wastewater, an oxidation-reduction reaction occurs between the amorphous alloy and heavy metal ions, and corresponding inert elemental heavy metals will precipitate out in the form of precipitation, which means that corresponding solid-liquid separation treatment needs to be carried out on the generated sludge in wastewater treatment. The wide wastewater treatment performance of amorphous alloy also further leads to the inevitable generation of impurity gases such as hydrogen and ammonia during the wastewater treatment process. For safety and other factors, waste gas collection needs to be carried out during the reaction process.

[0004] The application number 202010048211.8 discloses the preparation and application of FeCoNi amorphous alloy strips, which has high efficiency in catalytic treatment of industrial wastewater. However, amorphous alloy is a brittle material, and strip-shaped amorphous alloy is easy to be damaged, affecting its performance during use. Although amorphous alloy powder can effectively solve the brittle fracture problem of strip-shaped amorphous alloy, and the powdered amorphous alloy has higher catalytic efficiency, its recycling problem still needs to be solved urgently. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above deficiencies and provide an intelligent device for solid-liquid separation and waste gas collection of wastewater catalyzed by amorphous alloy, which can effectively achieve high efficiency, sufficient reaction, and recyclable and reusable amorphous alloy, and has the functions of solid-liquid separation of reaction products and waste gas collection.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] See also Figure 1 、 Figure 2 and Figure 3, an intelligent device for solid-liquid separation and waste gas collection of wastewater catalyzed by amorphous alloy, comprising a wastewater sedimentation tank 1. A sewage inlet 1-1, a sewage outlet 1-2 and a waste gas outlet 2-1 are provided on the wastewater sedimentation tank 1. An electric motor 3 is arranged outside the wastewater sedimentation tank 1. The driving shaft of the electric motor 3 extends into the wastewater sedimentation tank 1. A spiral auger 9 is arranged on the driving shaft of the electric motor 3. A fluid rotating impeller 6 and an amorphous alloy loading device 7 are sleeved on the driving shaft of the electric motor 3; an external thread is provided at the top end of the amorphous alloy loading device 7, and an internal thread is provided in the shaft hole of the fluid rotating impeller 6. The external thread of the amorphous alloy loading device 7 meshes with the internal thread of the fluid rotating impeller 6. A threaded sleeve 5 is arranged above the fluid rotating impeller 6. The threaded sleeve 5 is sleeved on the driving shaft of the electric motor 3. A top cover 2 is arranged at the top of the wastewater sedimentation tank 1. A nut 4 is arranged on the top cover 2. One end of the threaded sleeve 5 is connected to the fluid rotating impeller 6, and the other end passes through the top cover 2 and is connected to the nut 4. The sewage inlet 1-1 is higher than the sewage outlet 1-2, and the fluid rotating impeller 6 is arranged beside the sewage inlet 1-1. Under the impact of the water flow at the sewage inlet 1-1, the water flow impacts the fluid rotating impeller 6 to rotate. The fluid rotating impeller 6 drives the amorphous alloy loading device 7 and the filter screen 10 to rotate, so that the amorphous alloy powder fully reacts with the sewage. The waste gas outlet 2-1 is arranged at the top of the wastewater sedimentation tank 1. A control valve is arranged on the sewage inlet 1-1. A light sensor 8 is arranged at the sewage outlet 1-2.

[0029] See Figure 4 and Figure 5 , the amorphous alloy loading device 7 is filled with amorphous alloy powder. The particle size of the amorphous alloy powder is 50-150 microns, and the outer surface of the amorphous alloy loading device 7 is covered with a filter screen 10. The aperture of the filter screen is 10-40 microns.

[0030] Preferably, the amorphous alloy powder is any one or any combination of Fe-based amorphous alloy, Mg-based amorphous alloy, Cu-based amorphous alloy, Co-based amorphous alloy or Al-based amorphous alloy.

[0031] Preferably, the amorphous alloy loading device 7 is made of PET material.

[0032] In consideration that although amorphous alloy has high-efficiency sewage catalytic ability, related by-products may be generated. Therefore, in addition to meeting the basic reaction function, the present invention also has the functional characteristics of solid-liquid separation and waste gas collection.

[0033] See Figure 2 and Figure 3, Sewage enters from the sewage inlet 1-1 and is under the action of the impact fluid rotating impeller 6. After the reaction, the sewage is discharged through the sewage outlet 1-2. During this process, harmful gases such as impurities are generated and discharged through the exhaust gas outlet on one side of the top cover 2. At the same time, precipitation is generated. The precipitation penetrates through the filter screen and gradually accumulates at the sludge outlet 1-3 of the wastewater sedimentation tank 1. Among them, the sludge outlet is in a normally closed state. When the sludge accumulation amount approaches the light sensor 8 near the sewage outlet 1-2, an instruction is sent to close the sewage inlet 1-1, open the sludge outlet 1-3, and start the motor 3 to drive the rotation of the shaft of the screw auger 9 to achieve solid-liquid separation and discharge the sludge. The outside of the exhaust gas outlet 2-1 is connected to a gas collection device, and the sludge outlet 1-3 is connected to a sludge compression collection box. The closing of the sewage inlet is controlled by a control valve at the inlet.

[0034] The light sensor 8 installed near the sewage outlet 1-2 is embedded in the inner wall of the wastewater sedimentation tank 1. Considering the influence of the low original light intensity in the wastewater sedimentation tank, a light source indicator is set beside the light sensor 8. When the sludge submerges the indicator, the light intensity decreases, and the light sensor sends a prompt message. The signal of the light sensor propagates the signal flow through the local area network.

[0035] The screw auger 9 passes through the amorphous alloy load device 7, the fluid rotating impeller 6 and the shaft hole of the sleeve 5 in sequence, and passes through the top cover and is connected to the motor 3 by means of a coupling.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the technical solutions of the present invention. Those skilled in the art should understand that without departing from the spirit and principle of the present invention, the technical solutions can be modified and replaced simply in several ways, and these modifications and replacements also fall within the protection scope covered by the claims.
