Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, and in particular to a multi-stage exhaust gas treatment device for carbon source recovery. Background Technology

[0002] During industrial production, various combustion equipment and chemical reaction devices generate a large amount of exhaust gas containing carbon source components. If this exhaust gas is directly emitted, it will not only cause serious environmental pollution, but also lead to a huge waste of carbon resources.

[0003] However, existing exhaust gas treatment devices have many shortcomings in carbon source recovery. Traditional treatment devices mostly use a single filtration or adsorption method, which has limited adsorption and activation capacity for carbon source components in exhaust gas. It is difficult to fully capture carbon sources in exhaust gas, resulting in low carbon source recovery efficiency, poor exhaust gas treatment effect, and inability to meet increasingly stringent environmental emission standards.

[0004] To address the aforementioned issues, we propose a multi-stage exhaust gas treatment device for carbon source recovery. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage tail gas treatment device for carbon source recovery.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-stage exhaust gas treatment device for carbon source recovery includes an exhaust gas treatment chimney. Inside the chimney, from bottom to top, are sequentially arranged a primary filter screen, a spray filtration mechanism, and a carbon source treatment mechanism. The carbon source treatment mechanism includes a storage tank filled with a bimetallic catalyst. A metal heating tube is fixedly installed inside the storage tank. A metal contact plate is fixedly installed on the outer wall of the storage tank, and the metal contact plate is electrically connected to the metal heating tube. Fine holes are evenly distributed on the storage tank, with the inner diameter of the holes being smaller than the particle size of the bimetallic catalyst. Ear plates are fixedly connected to both sides of the storage tank, and the ear plates are screwed onto the inner wall of the exhaust gas treatment chimney.

[0008] Furthermore, the inner wall of the exhaust gas treatment chimney is provided with a power supply metal contact electrode adapted to the metal contact plate, and the power supply metal contact electrode abuts against the metal contact plate.

[0009] Furthermore, a temperature sensor is fixedly installed on the upper side of the inner wall of the exhaust gas treatment chimney.

[0010] Furthermore, a feeding pipe is fixedly installed on the upper side of the storage box, and a cover is fastened to the upper side of the feeding pipe.

[0011] Furthermore, the primary filter screen is screwed onto the inner wall of the exhaust gas treatment chimney.

[0012] Furthermore, the spray filtration mechanism includes a support plate and a water injection pipe. The support plate is obliquely and fixedly installed on the inner wall of the exhaust gas treatment chimney, and bent pipes are evenly and fixedly installed on the support plate.

[0013] Furthermore, the water injection pipe is fixedly installed on the inner wall of the exhaust gas treatment chimney and extends to the outer side of the exhaust gas treatment chimney. Several ring pipes are fixedly connected to the inner end of the water injection pipe, and several spray pipes are fixedly installed on the lower side of the ring pipes.

[0014] Furthermore, the exhaust gas treatment chimney is fixedly installed with support legs on both sides, and a controller is fixedly installed on the outer wall of the exhaust gas treatment chimney.

[0015] Furthermore, a wastewater tank is fixedly installed on the side of the exhaust gas treatment chimney, and a water outlet pipe is fixedly installed on the lower side of the wastewater tank, with a solenoid valve fixedly installed on the water outlet pipe.

[0016] Compared with related technologies, the multi-stage tail gas treatment device for carbon source recovery proposed in this utility model has the following beneficial effects:

[0017] In this invention, a multi-stage exhaust gas treatment device for carbon source recovery is described. Through a carbon source treatment mechanism, a storage tank within the mechanism is filled with a bimetallic catalyst for carbon source recovery. When exhaust gas enters the storage tank through fine holes, it is heated by a metal heating tube to enhance the activity of the bimetallic catalyst. This, in turn, strengthens the catalyst's adsorption and activation capacity for carbon source components in the exhaust gas, improving the filtration effect on the flue gas. Simultaneously, the adsorbed carbon source powder can be used later for the synthesis of single-walled carbon nanotubes, improving resource utilization. Attached Figure Description

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

[0026] Reference Figures 1-6 A multi-stage exhaust gas treatment device for carbon source recovery includes an exhaust gas treatment chimney 1. Inside the exhaust gas treatment chimney 1, from bottom to top, are arranged a primary filter screen 7, a spray filtration mechanism 8, and a carbon source treatment mechanism 9. The carbon source treatment mechanism 9 includes a storage tank 91 filled with a bimetallic catalyst. A metal heating tube 97 is fixedly installed inside the storage tank 91. A metal contact plate 94 is fixedly installed on the outer wall of the storage tank 91, electrically connected to the metal heating tube 97. Fine holes 95 are evenly distributed on the storage tank 91, with an inner diameter smaller than the particle size of the bimetallic catalyst. Ear plates 96 are fixedly connected to both sides of the storage tank 91, screwed onto the inner wall of the exhaust gas treatment chimney 1. A power supply metal contact electrode adapted to the metal contact plate 94 is provided on the inner wall of the exhaust gas treatment chimney 1, abutting against the metal contact plate 94. The primary filter screen 7 is screwed onto the inner wall of the exhaust gas treatment chimney 1.

[0027] With the above setup, during exhaust gas treatment, the exhaust gas is introduced from the bottom of the exhaust gas treatment chimney 1, and the primary filter screen 7 can effectively intercept dust particles and large-diameter impurities in the exhaust gas, thus performing preliminary treatment on the flue gas.

[0028] In this method, a temperature sensor 10 is fixedly installed on the upper side of the inner wall of the exhaust gas treatment chimney 1.

[0029] With the above-mentioned setup, the temperature sensor 10 is used to monitor the heating temperature at the carbon source processing unit 9. The controller 3 can be used for precise temperature control to improve the activity of the bimetallic catalyst and increase the carbon source adsorption efficiency.

[0030] In this method, a feeding pipe 92 is fixedly installed on the upper side of the storage box 91, and a cover 93 is fastened to the upper side of the feeding pipe 92.

[0031] With the above-described setup, the feed pipe 92 is used to add or replace the bimetallic catalyst.

[0032] In this method, the spray filtration mechanism 8 includes a support plate 81 and a water injection pipe 83. The support plate 81 is inclined and fixedly installed on the inner wall of the exhaust gas treatment chimney 1. Bent pipes 82 are evenly distributed and fixedly installed on the support plate 81. The water injection pipe 83 is fixedly installed on the inner wall of the exhaust gas treatment chimney 1 and passes through to the outside of the exhaust gas treatment chimney 1. Several ring pipes 84 are fixedly connected to the inner end of the water injection pipe 83. Several spray pipes 85 are fixedly installed on the lower side of the ring pipes 84.

[0033] With the above-described setup, the solution used for spraying is a specially prepared alkaline aqueous solution. The alkaline aqueous solution is injected into several spray pipes 85 through the water injection pipe 83 and the ring pipe 84, forming a dense downward spraying effect. This can neutralize the acidic components in the exhaust gas and also perform preliminary wetting treatment on the exhaust gas, creating favorable conditions for the subsequent catalytic reaction. The falling water flows onto the support plate 81 and then flows into the wastewater tank 4. The bend pipe 82 on the support plate 81 is used to provide a flue gas passage. After the flue gas passes through the primary filter screen 7, it continues to enter the upper side of the support plate 81 through the bend pipe 82. The bend of the bend pipe 82 is set downward so that the water flow will not fall into the bend pipe 82 during spraying, thus preventing the primary filter screen 7 on the lower side from being affected by the spraying.

[0034] In this method, support legs 2 are fixedly installed on both sides of the exhaust gas treatment chimney 1, a controller 3 is fixedly installed on the outer wall of the exhaust gas treatment chimney 1, a wastewater tank 4 is fixedly installed on the side of the exhaust gas treatment chimney 1, a water outlet pipe 5 is fixedly installed on the lower side of the wastewater tank 4, and a solenoid valve 6 is fixedly installed on the water outlet pipe 5.

[0035] With the above configuration, the solenoid valve 6 is used to control the opening and closing state of the water outlet pipe 5.

[0036] The working principle of the multi-stage tail gas treatment device for carbon source recovery provided by this utility model is as follows:

[0037] First, the carbon-containing exhaust gas to be treated enters the device from the bottom of the exhaust gas treatment chimney 1. The primary filter screen 7 serves as the first treatment process, effectively intercepting dust particles and large-diameter impurities mixed in the exhaust gas, completing the initial purification of the exhaust gas and reducing the burden on subsequent treatment.

[0038] The exhaust gas, after preliminary filtration, flows upward and enters the treatment area of ​​the spray filtration mechanism 8. An external water source delivers a prepared alkaline aqueous solution through the water injection pipe 83 to several ring pipes 84, which then form a dense downward spray effect through the spray pipes 85 below the ring pipes 84. The alkaline aqueous solution not only neutralizes the acidic components in the exhaust gas but also moistens it, creating favorable conditions for subsequent catalytic reactions. At the same time, the evenly distributed curved pipes 82 on the inclined support plate 81 provide an upward flow channel for the exhaust gas, and the downward-facing design of the curved pipes 82 prevents the spray water from entering, ensuring that the primary filter screen 7 below is not affected. The wastewater generated by the spray flows to the support plate 81 and collects in the wastewater tank 4. After a certain amount has been treated, the controller 3 controls the solenoid valve 6 to open the outlet pipe 5, discharging the wastewater for further treatment.

[0039] The exhaust gas, after completing the spray treatment, continues upward and enters the carbon source treatment mechanism 9. The exhaust gas enters the storage tank 91 through the fine holes 95 evenly distributed on the storage tank 91 (the inner diameter of which is smaller than the particle size of the bimetallic catalyst to prevent catalyst leakage). At this time, the power supply metal contact electrode on the inner wall of the exhaust gas treatment chimney 1, which abuts against the metal contact plate 94, supplies power. The current is conducted through the metal contact plate 94 to the metal heating tube 97. The metal heating tube 97 generates heat, which improves the activity of the bimetallic catalyst. At a suitable temperature (monitored by the temperature sensor 10 on the upper side of the inner wall of the exhaust gas treatment chimney 1, and precisely controlled by the controller 3), the bimetallic catalyst efficiently adsorbs and activates the carbon source components in the exhaust gas, greatly improving the carbon source recovery efficiency. The adsorbed carbon source powder can be used for the synthesis of single-walled carbon nanotubes in the later stage, improving resource utilization.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
