Description

Technical Field

[0001] This utility model relates to the field of activated carbon regeneration technology, and in particular to a portable small-scale activated carbon high-temperature regeneration device. Background Technology

[0002] At present, traditional waste gas treatment still relies heavily on activated carbon adsorption technology. Activated carbon adsorption technology has the advantages of high purification efficiency, especially for low-concentration gases. However, the adsorption capacity of activated carbon will decrease or be lost after a period of use, and it needs to be replaced or regenerated. Replacing activated carbon will generate secondary pollutants and hazardous waste, so activated carbon regeneration is particularly important.

[0003] For example, CN111185143A discloses a waste activated carbon regeneration process, which requires equipment including, but not limited to, a desorption box, a gas-driven device, and a condensation device; wherein: the desorption box is for placing saturated activated carbon containing pollutants, and the desorption box has a frequency conversion microwave heating device; the gas-driven device has an input end connected to the desorption box for transferring VOCs-containing thermal vapors released from the saturated activated carbon; the condensation device includes a heat exchanger and a freezing chamber connected to the output end of the gas-driven device, the gas-driven device introduces VOCs thermal vapors into the freezing chamber, and the VOCs vapors will condense into liquid under pressure and low temperature conditions, and be recovered through valves in the heat exchanger and the freezing chamber.

[0004] For example, CN110975515A discloses an activated carbon adsorption purification system and method for regeneration by electric heating, including a filter, a cooler, and at least two activated carbon adsorbers. The activated carbon adsorbers are equipped with an adsorption purification unit, which consists of an activated carbon fiber bed, electrodes, a temperature sensor, and an enclosure structure. The activated carbon fiber bed is made of stacked activated carbon fiber fabric. A temperature sensor is installed inside the bed. Electrodes are installed on any two opposite end faces of the bed. The electrodes are formed by overlapping conductive strips with layers of activated carbon fiber fabric or by overlapping conductive strips with several layers of activated carbon fiber fabric.

[0005] However, existing activated carbon regeneration equipment or systems are expensive to purchase, occupy a large space, and consume a lot of energy, making them less than ideal for small and medium-sized factories.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0007] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a portable small-scale activated carbon high-temperature regeneration device, which has advantages such as low purchase cost, small space occupation, energy saving and practicality, and is suitable for small and medium-sized factories for activated carbon regeneration.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A portable, small-scale activated carbon high-temperature regeneration device includes:

[0010] The chamber has a baking chamber, a guide air duct, and a high-temperature decomposition chamber arranged sequentially inside. An air inlet is provided at one end of the chamber corresponding to the baking chamber, and a cooling circulating fan is installed at the air inlet. An air outlet is provided at one end of the chamber corresponding to the high-temperature decomposition chamber. The other end of the baking chamber is connected to the other end of the high-temperature decomposition chamber through the guide air duct, so that: the airflow enters the baking chamber through the air inlet, then enters the guide air duct from the other end of the baking chamber, then enters the other end of the high-temperature decomposition chamber, and finally exits from the air outlet.

[0011] The activated carbon regeneration drawer is pull-out and located inside the baking chamber.

[0012] The first electric heating element is located inside the baking chamber;

[0013] A baking temperature sensor is located inside the baking chamber;

[0014] The second electric heating element is located in the high-temperature decomposition chamber;

[0015] The PLC intelligent control box is located outside the box and is connected to the cooling circulation fan, the first electric heating tube, the baking temperature sensor, and the second electric heating tube.

[0016] As a preferred embodiment, the baking chamber, the air duct, and the high-temperature decomposition chamber are arranged horizontally side by side, and each of them is vertically arranged. The air inlet is located at the lower end of one outer side of the baking chamber. The upper end of the baking chamber is provided with an organic gas outlet, which connects to the upper end of the air duct. The lower end of the air duct connects to the lower end of the high-temperature decomposition chamber. The air outlet is located at the top or the outer side near the top of the high-temperature decomposition chamber.

[0017] As a preferred embodiment, the organic gas exhaust port and the air inlet are located on opposite sides of the baking chamber.

[0018] As a preferred embodiment, both the baking chamber and the high-temperature decomposition chamber are covered with a heat-insulating protective layer.

[0019] As a preferred embodiment, multiple activated carbon regeneration drawers are provided and arranged with vertical spacing; the baking temperature sensor is located in the area between adjacent activated carbon regeneration drawers.

[0020] As a preferred embodiment, the first electric heating tube is arranged below the uppermost activated carbon regeneration drawer and above the air inlet.

[0021] As a preferred embodiment, the first electric heating tube is also arranged in the area between at least two adjacent activated carbon regeneration drawers.

[0022] As a preferred embodiment, the high-temperature decomposition chamber is also equipped with a decomposition temperature sensor, which is connected to the PLC intelligent control box.

[0023] As a preferred embodiment, the cooling circulating fan is connected to a frequency converter, and the first and second electric heating tubes are each provided with several groups arranged at vertical intervals. The PLC intelligent control box is connected to the frequency converter and several first and second electric heating tubes respectively.

[0024] As a preferred embodiment, the high-temperature decomposition chamber is further provided with a honeycomb catalytic layer, which is disposed above at least one second electric heating tube, so that the gas entering the high-temperature decomposition chamber passes through the area where at least one second electric heating tube is located and then passes upward through the honeycomb catalytic layer.

[0025] This invention has significant advantages and beneficial effects compared with existing technologies. Specifically, as can be seen from the above technical solution, it mainly involves sequentially arranging a baking chamber, a guide air duct, and a high-temperature decomposition chamber inside the housing. A cooling circulating fan is installed at the air inlet of the housing, and the air outlet of the housing is located in the high-temperature decomposition chamber. The baking chamber is connected to the high-temperature decomposition chamber via the guide air duct. Furthermore, an activated carbon regeneration drawer, a first electric heating element, and a baking temperature sensor are installed inside the baking chamber, while a second electric heating element is installed inside the high-temperature decomposition chamber. A PLC intelligent control box is installed outside the housing for connecting to the cooling circulating fan, the first electric heating element, the baking temperature sensor, and the second electric heating element. Thus, a portable small activated carbon high-temperature regeneration device is obtained. The activated carbon to be regenerated is placed into the activated carbon regeneration drawer... After the activated carbon is placed in the regeneration drawer, the cooling circulating fan, the first electric heating element, and the second electric heating element are turned on. The first electric heating element generates high temperature to bake the activated carbon, causing the adsorbed organic matter to desorb. The desorbed organic matter enters the high-temperature decomposition chamber with the airflow, is decomposed at high temperature, and is then discharged through the air outlet. In particular, the baking temperature sensor provides real-time temperature feedback, and the PLC intelligent control box can monitor the internal operating status of the device in real time. Furthermore, the PLC intelligent control box can adjust the airflow of the cooling circulating fan (or the air intake speed) according to the real-time temperature, thereby precisely adjusting and controlling the baking temperature and effectively improving the regeneration efficiency. This portable small activated carbon high-temperature regeneration device has advantages such as low purchase cost, small footprint, energy saving, and practicality, and is suitable for small and medium-sized factories for activated carbon regeneration.

Detailed Implementation

[0035] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of various embodiments of the present invention.

[0036] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] A portable, small-scale activated carbon high-temperature regeneration device includes a housing 10, an activated carbon regeneration drawer 20, a first electric heating element 30, a baking temperature sensor 40, a second electric heating element 50, and a PLC intelligent control box 60. Specifically:

[0038] The housing 10 has a baking chamber 101, a guide air duct 102, and a high-temperature decomposition chamber 103 arranged sequentially inside. An air inlet 11 is provided at one end of the housing 10 corresponding to the baking chamber 101, and a cooling circulating fan 104 is installed at the air inlet 11. An air outlet 12 is provided at one end of the housing 10 corresponding to the high-temperature decomposition chamber 103. The other end of the baking chamber 101 is connected to the other end of the high-temperature decomposition chamber 103 via the guide air duct 102, so that airflow enters the baking chamber 101 through the air inlet 11, then enters the guide air duct 102 from the other end of the baking chamber 101, then enters the other end of the high-temperature decomposition chamber 103, and finally exits through the air outlet 12. A set of casters can be provided at the bottom of the housing 10, and an inspection port can be provided at the top of the housing 10. The set of casters includes directional wheels and omnidirectional wheels, and the omnidirectional wheels can be equipped with an electromagnetic braking device. A handle or push handle is also typically provided on the housing 10. Preferably, the air outlet 12 can also be equipped with a quick-connect flange interface 121, which is adapted to the size of the air inlet end of the adsorption tank. For general activated carbon high-temperature regeneration requirements, the organic matter after high-temperature decomposition can be discharged through the air outlet 12 in compliance with standards. In some special cases, if the gas detector 70 installed at the air outlet 12 indicates that the gas quality is not ideal, the flange interface 121 can be connected to the adsorption tank, and the gas can be purified by the adsorption tank before being discharged. Similarly, the activated carbon in the adsorption tank can also be disassembled and placed into the activated carbon regeneration drawer 20 of the portable small activated carbon high-temperature regeneration device for regeneration.

[0039] The activated carbon regeneration drawer 20 is pull-out and installed in the baking chamber 101 for taking out and putting in activated carbon. Typically, the activated carbon regeneration drawer 20 adopts a stainless steel wire mesh basket structure, with vertically connected guide grooves on its bottom and outer periphery. In this way, the hot air at the bottom of the activated carbon regeneration drawer 20 flows upward through the bottom guide groove, and another part of the hot air flows upward through the guide groove on the outer periphery of the activated carbon regeneration drawer 20, forming forced convection heating, which is beneficial to the uniformity of the baking temperature in the baking chamber 101.

[0040] The first electric heating tube 30 is disposed in the baking chamber 101 to generate high temperature for baking activated carbon, so that the organic matter adsorbed on the activated carbon is desorbed.

[0041] The baking temperature sensor 40 is installed inside the baking chamber 101 to monitor the temperature of the baking chamber 101 in real time, thereby facilitating precise control of the baking temperature.

[0042] The second electric heating element 50 is disposed in the high-temperature decomposition chamber 103, so that the desorbed organic matter is decomposed at high temperature in the high-temperature decomposition chamber 103 and then discharged through the air outlet 12. These first electric heating elements 30 and second electric heating elements 50 are preferably made of high-strength 316 stainless steel pipes, which can be spiral pipes.

[0043] The PLC intelligent control box 60 is located outside the housing 10 and is connected to the cooling circulating fan 104, the first electric heating tube 30, the baking temperature sensor 40, and the second electric heating tube 50. In some embodiments, for the rated first electric heating tube 30, the baking temperature can be fed back to the PLC intelligent control box 60 in real time by the baking temperature sensor 40, and the air volume of the cooling circulating fan 104 can be controlled as needed. For example, if the intake speed of the outside cold air is high, the baking temperature in the baking chamber 101 will be adjusted to decrease; conversely, if the intake speed decreases, the baking temperature in the baking chamber 101 will be adjusted to increase. The PLC intelligent control box 60 controlling the air volume of the cooling circulating fan 104 is a mature technology. It is generally achieved by adjusting the fan speed rather than directly controlling the power, because the air volume and the fan speed are linearly related. The air volume output can be directly changed by adjusting the fan motor speed, while the power is cubically related to the speed. The power change is a result of the speed adjustment. The PLC intelligent control box 60 outputs analog signals to control the frequency converter, adjust the power supply frequency of the fan motor to achieve stepless speed regulation, and better regulate the air volume.

[0044] Furthermore, the baking chamber 101, the air duct 102, and the high-temperature decomposition chamber 103 are arranged horizontally side by side, each with its own vertical configuration. The air inlet 11 is located at the lower outer end of one side of the baking chamber 101. The upper end of the baking chamber 101 has an organic gas outlet, which connects to the upper end of the air duct 102. The lower end of the air duct 102 connects to the lower end of the high-temperature decomposition chamber 103. The air outlet 12 is located at the top or near the top of the outer side of the high-temperature decomposition chamber 103. The organic gas outlet and the air inlet 11 are located on opposite sides of the baking chamber 101. Similarly, the upper end of the air duct 102 serves as the air inlet, and the lower end serves as the air outlet, both located on opposite sides of the air duct 102. In addition, the lower end of the air duct 102 is connected to the organic gas inlet at the lower end of one side of the high-temperature decomposition chamber 103. The organic gas inlet and the air outlet 12 are also located on opposite sides of the high-temperature decomposition chamber 103.

[0045] Furthermore, both the baking chamber 101 and the high-temperature decomposition chamber 103 are covered with a heat insulation protective layer, which can effectively protect the device shell, improve heat utilization, and reduce energy consumption. The heat insulation protective layer can adopt existing mature technologies. The material structure of the heat insulation protective layer needs to take into account high temperature resistance, thermal resistance performance, and mechanical stability. Fiber materials (such as aluminum silicate cotton, also referring to ceramic fiber), mineral wool (such as rock wool board, glass wool), and composite board materials can be selected. The specific structure can be a single-layer structure, a multi-layer composite structure, or a sandwich panel structure, etc. Among them, the single-layer structure can be aluminum silicate cotton attached to the outer wall of the stainless steel inner liner, etc. The multi-layer composite structure can be a three-layer structure (such as an outer layer of galvanized steel plate, a middle layer of rock wool board and polyurethane foam, and an inner layer of stainless steel plate), and the sandwich panel structure can be designed as double-sided color steel plate sandwiched with polystyrene core material, etc. Ceramic fiber + metal reflective layer can also be used (for example, from the inside to the outside, the layers are ceramic fiber layer, aerogel layer and aluminum foil reflective layer).

[0046] Furthermore, multiple activated carbon regeneration drawers 20 are provided, arranged vertically at intervals; the baking temperature sensor 40 is located in the area between vertically adjacent activated carbon regeneration drawers 20. Typically, multiple baking temperature sensors 40 are also arranged to provide real-time feedback on the temperature of different areas within the baking chamber 101. For example, the first electric heating tube 30 is arranged below the uppermost activated carbon regeneration drawer 20 and above the air inlet 11. In other embodiments, the first electric heating tube 30 may also be arranged in the area between at least two vertically adjacent activated carbon regeneration drawers 20.

[0047] Furthermore, a decomposition temperature sensor 80 is also installed in the high-temperature decomposition chamber 103, and the decomposition temperature sensor 80 is connected to the PLC intelligent control box 60. The cooling circulation fan 104 is connected to a frequency converter. The first electric heating tube 30 and the second electric heating tube 50 are each arranged in several groups with vertical spacing. The PLC intelligent control box 60 is connected to the frequency converter and several first electric heating tubes 30 and second electric heating tubes 50 respectively, so as to dynamically adjust the speed of the cooling circulation fan 104 and the number of first electric heating tubes 30 activated according to the feedback value of the baking temperature sensor 40, and dynamically adjust the number of second electric heating tubes 50 activated according to the feedback value of the decomposition temperature sensor 80, effectively improving the regeneration efficiency. Of course, the air intake volume (air volume size or even intermittent stopping of the cooling circulation fan 104) and the heating capacity of the first electric heating tube 30 and the second electric heating tube 50 can also be dynamically adjusted in combination with the feedback value of the gas detector 70, so that the gas at the outlet can meet the standards for direct discharge under normal circumstances. Considering cost, the gas detector 70's feedback value is manually checked and read. The detection value is input into the human-machine interface, and then the PLC intelligent control box 60 adjusts the air intake volume and the heating capacity of the first electric heating tube 30 and the second electric heating tube 50. In other embodiments, the gas detector 70 can be connected to the PLC intelligent control box 60 (wired or wireless communication is acceptable).

[0048] Furthermore, a honeycomb catalytic layer 90 is also provided inside the high-temperature decomposition chamber 103. The honeycomb catalytic layer 90 is disposed above at least one second electric heating tube 50, so that the gas entering the high-temperature decomposition chamber 103 passes through the area where at least one second electric heating tube 50 is located and then passes upward through the honeycomb catalytic layer 90, effectively improving the decomposition rate of organic matter. Typically, the honeycomb catalytic layer 90 is designed by combining a porous structure with high-temperature resistant materials. The honeycomb catalytic layer 90 is a commonly used structure in the environmental protection field. In the case of multiple sets of second electric heating tubes 50, two or more sets of honeycomb catalytic layers 90 can also be provided, with the honeycomb catalytic layer 90 located in the area between adjacent second electric heating tubes 50.

[0049] In addition, the PLC intelligent control box 60 can adopt the most classic control algorithm module in the industrial control field: the PID algorithm module. By embedding the PID algorithm module in the PLC intelligent control box 60, it is currently widely used in industrial control fields such as oven temperature control and motor control. It can effectively suppress temperature overshoot, has a fast response speed, and is beneficial to the stability of the control system. The PLC intelligent control box 60 is equipped with a human-machine interface, which displays real-time temperature curves, energy consumption data, and fault diagnosis codes.

[0050] It should be noted that the above embodiments are not intended to limit the specific feasible implementation of this utility model. Without contradicting each other, the technical features of each embodiment can be flexibly modified and combined to obtain more different implementation schemes.

[0051] The key design feature of this invention lies in the sequential arrangement of a baking chamber 101, a guide air duct 102, and a high-temperature decomposition chamber 103 within a housing 10. A cooling circulating fan 104 is installed at the air inlet 11 of the housing 10, and the air outlet 12 of the housing 10 is located in the high-temperature decomposition chamber 103. The baking chamber 101 is connected to the high-temperature decomposition chamber 103 via the guide air duct 102. Furthermore, an activated carbon regeneration drawer 20, a first electric heating element 30, and a baking temperature sensor 40 are installed within the baking chamber 101. A second electric heating element 50 is installed within the high-temperature decomposition chamber 103. A PLC intelligent control box 60 is installed outside the housing 10 for connecting to the cooling circulating fan 104, the first electric heating element 30, the baking temperature sensor 40, and the second electric heating element 50. This results in a portable, small-scale activated carbon high-temperature regeneration device. After placing the activated carbon into the activated carbon regeneration drawer 20, the cooling circulation fan 104, the first electric heating tube 30, and the second electric heating tube 50 are turned on. The first electric heating tube 30 generates high temperature to bake the activated carbon, causing the adsorbed organic matter to desorb. The desorbed organic matter enters the high temperature decomposition chamber 103 with the airflow, is decomposed by the high temperature, and is then discharged from the air outlet 12. In particular, the baking temperature sensor 40 provides real-time temperature feedback, and the PLC intelligent control box 60 can monitor the internal operating status of the device in real time. Furthermore, the PLC intelligent control box 60 can control the airflow (or air intake speed) of the cooling circulation fan 104 according to the real-time temperature, thereby precisely adjusting and controlling the baking temperature and effectively improving the regeneration efficiency. This portable small activated carbon high temperature regeneration device has advantages such as low purchase cost, small space occupation, energy saving, and practicality, and is suitable for small and medium-sized factories for activated carbon regeneration.

[0052] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
