Abstract
Description
Technical Field
[0001] The utility model relates to a catalyst recovery device, in particular to a carbon-based catalyst incineration device. Background Art
[0002] Adding catalysts is a common method to speed up chemical reactions. Carbon-based catalysts are one type of catalyst and are widely used in chemical synthesis in the pharmaceutical and chemical industries, energy conversion in fuel cells, and harmful gas treatment. If the catalyst is not properly treated after it is discarded, it will not only waste resources, but also cause serious pollution to the environment.
[0003] Incineration of waste catalysts is an important form of catalyst recovery. Using waste catalyst incineration technology to incinerate waste carbon-based catalysts at high temperatures can effectively decompose or solidify harmful substances such as heavy metals and toxic gases, reduce potential harm to the environment, and recover precious metals.
[0004] However, the current catalyst incineration device needs to preheat itself when incinerating the catalyst, which will generate a lot of energy consumption. Utility Model Content
[0005] Purpose of the utility model: The purpose of the utility model is to provide an energy-saving carbon-based catalyst incineration device.
[0006] Technical solution: The carbon-based catalyst incineration device described in the utility model includes an incineration furnace and a lifting device. The lifting device is arranged below the incineration furnace. The lifting device includes a lifting platform for placing and transporting the carbon-based catalyst. The lifting platform is controlled by a control module to move up and down. The lifting platform can close the opening at the bottom of the incineration furnace when it is in the highest position.
[0007] When the carbon-based catalyst incineration device incinerates the waste carbon-based catalyst, the waste carbon-based catalyst is placed on a lifting platform and ignited in advance by utilizing the characteristic that the carbon-based catalyst can continue to burn after being ignited. The ignited waste carbon-based catalyst is then raised to the incineration furnace by the lifting platform for full combustion to recover precious metals and other substances. Since the carbon-based catalyst incineration device does not need to actively heat up to the ignition point of the carbon-based catalyst, nor does it need to continuously heat the material, it can greatly reduce energy consumption in the recycling process, saving energy and protecting the environment.
[0008] The carbon-based catalyst incineration device is also equipped with a crucible, which is used to hold the carbon-based catalyst. The opening on the lifting platform corresponds to an orthographic projection area, and the crucible is located in the orthographic projection area. Sieve holes can be set inside the crucible. Before the lifting device sends the carbon-based catalyst into the incineration furnace, the carbon-based catalyst in the crucible is ignited in advance. The crucible is located in the orthographic projection area to facilitate the smooth delivery of the crucible into the incineration furnace. Sieve holes are set in the crucible. When the carbon-based catalyst burns in the incineration furnace, the sieve holes help to increase the contact area between the air and the carbon-based catalyst and improve the combustion rate of the carbon-based catalyst. After the combustion is completed, the crucible with sieve holes is convenient for screening and collecting ash.
[0009] The lifting device also includes a motor and a lifting rod extending in a height direction, the lifting rod is connected to the lifting platform, and the motor drives the lifting rod to move and drives the lifting platform to move up and down.
[0010] The lifting rod may be a screw rod, which is connected to the lifting platform by bolts, and the motor drives the lifting rod to rotate, and drives the lifting platform to move up and down through thread transmission. Alternatively, the lifting rod is a hydraulic rod, and the lifting platform is fixedly connected to the lifting rod, and the motor drives the hydraulic pump to drive the lifting rod and the lifting platform to move up and down. The lifting platform moves up and down, which is convenient for taking and placing the crucible, and also convenient for sending the carbon-based catalyst into the incineration furnace for incineration.
[0011] The incinerator chamber is provided with an air inlet and an air outlet; the air inlet is used to connect to an air compressor to deliver air into the incinerator chamber; the air outlet is used to connect to an exhaust gas treatment device. Through the air inlet and the air outlet, the incinerator chamber establishes a circulation with the external air, so that the waste carbon-based catalyst can be continuously exposed to the air for efficient and sufficient combustion. The exhaust gas treatment device further reduces environmental pollution during the recovery of the carbon-based catalyst.
[0012] The control module includes a pressure control valve for regulating the air intake pressure of the air intake port. The greater the air intake pressure, the faster the combustion rate of the carbon-based catalyst in the incineration furnace.
[0013] A temperature sensor and a pressure sensor are installed in the incinerator chamber, and the control module includes a display, which is electrically connected to the temperature sensor and the pressure sensor to monitor the temperature and pressure in the incinerator chamber. According to the temperature and pressure values displayed by the display, the operator can know the current combustion process in the incinerator chamber, which is convenient for the operator to regulate the combustion rate of the carbon-based catalyst.
[0014] The furnace wall of the incineration furnace comprises a heat-insulating layer, which effectively reduces the heat loss in the incineration furnace during incineration and improves the incineration efficiency.
[0015] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. There is no need to set up a heating device. On the one hand, it reduces the overall power consumption, saves energy and is environmentally friendly. On the other hand, it can avoid the laying of cables for high-power equipment, reducing equipment costs and floor space; 2. By setting up an insulation layer, the loss of heat energy during the incineration process is greatly reduced, and the carbon-based catalyst is assisted to continue to burn, which further improves the incineration efficiency of the equipment, reduces energy consumption, and maximizes the utilization of resources; 3. By setting a pressure control valve, the air inlet pressure is adjusted to control the combustion rate of the carbon-based catalyst in the incineration furnace. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.
[0018] Example 1: Figure 1 As shown, the carbon-based catalyst incineration device described in the utility model includes an incineration device body and a control module 3 installed on the incineration device body. The incineration device body is provided with an incineration furnace 1 above and a material feeding chamber below. The incineration furnace 1 is provided with an air inlet 11 and an air outlet 12. A temperature sensor and a pressure sensor connected to the control module 3 by wires are installed in the incineration furnace 1. The furnace wall of the incineration furnace 1 includes an insulation layer and a fire-resistant layer. A lifting device 2 is installed in the material feeding chamber. The lifting device 2 includes a lifting platform 21, a motor 22 and a lifting rod 23. The lifting rod 23 is a screw, wherein the motor 22 is installed at the bottom of the material feeding chamber, the screw is connected to the motor 22 and extends to the incineration furnace 1 along the height direction, the lifting platform 21 is connected by bolts and screws, the motor 22 can drive the screw to rotate, and the rise and fall of the lifting platform 21 are controlled by the cooperation of the bolts and the screw.
[0019] The control module 3 is provided with a display 31, a power switch 33, a lifting platform up switch 34 for controlling the lifting platform 21 to move up and down, a lifting platform down switch 35, and a pressure control valve 32. The display 31 is connected to a temperature sensor and a pressure sensor, and can display the temperature and pressure in the incineration furnace 1 in real time. The pressure control valve 32 can adjust the intake pressure, thereby adjusting the rate at which the waste carbon-based catalyst is burned.
[0020] The carbon-based catalyst incineration device is also equipped with a crucible 4, and the crucible 4 is provided with sieve holes.
[0021] When the waste carbon-based catalyst is recycled and processed in this embodiment, the power switch 33 is first turned on, and the lifting platform 21 is adjusted to a position convenient for placing the crucible 4 through the lifting platform rising switch 34 or the lifting platform descending switch 35, and then the waste carbon-based catalyst is placed in the crucible 4 and placed on the lifting platform 21. After being placed, the waste catalyst is ignited, and then the waste carbon-based catalyst that can continue to burn by itself is raised to the incineration furnace 1 through the lifting device 2. The lifting platform 21 rises to the highest position and seals the bottom opening of the combustion furnace to isolate the combustion furnace and the material delivery chamber. During the combustion process, the air inlet 11 is opened and connected to the air compressor, the air outlet 12 is opened, and the tail gas treatment device is connected to establish the circulation of the incineration furnace 1 and the external air. According to the temperature and pressure data displayed on the display 31, the operator can adjust the pressure control valve 32 to control the intake pressure, thereby controlling the combustion rate of the waste carbon-based catalyst. When the temperature on the monitor 31 drops to room temperature and the reaction is finished, the lifting platform 21 is lowered through the lowering switch of the lifting platform 21, and the crucible 4 is taken out to realize the incineration recovery of the waste carbon-based catalyst.
[0022] When the carbon-based catalyst incineration device of this embodiment was tested for processing a waste hydrogen fuel cell carbon-based catalyst with a total weight of 900g and a carbon content of about 810g, the combustion process was completed within 5 hours, and the incineration furnace was able to cool to a safe temperature. After weighing the incinerated material, the remaining ash was measured to be 130.5g, that is, the carbon removal rate was about 95%. The traditional muffle furnace processes the same amount of waste carbon-based catalysts of the same type, and the whole process from heating to combustion to cooling takes 30 hours. In contrast, the carbon-based catalyst incineration device of this embodiment significantly improves the recovery efficiency, greatly reduces electricity consumption, and has a high carbon removal rate, which is energy-saving and environmentally friendly.
[0023] When the carbon-based catalyst incineration device of this embodiment was tested on a honeycomb briquette-type platinum-carbon catalyst with a total weight of 2kg and a carbon content of about 1740g, the combustion process was completed within 7 hours, and the incineration furnace was able to cool to a safe temperature. After weighing the incinerated material, the remaining ash was measured to be 294.8g, and the carbon removal rate was as high as 98%. This shows that the technical solution of the utility model can efficiently recycle different types of carbon-based catalysts.
