Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] like Figure 1-3 As shown, an unmanned intelligent waste gas purification device for factories includes a carbon box assembly 1, a pipeline connection system 2, a switching valve 3, a catalytic combustion device 4, a fan assembly 5, and an intelligent control system 6. The carbon box assembly 1 is connected to the catalytic combustion device 4 through the pipeline connection system 2. The switching valve 3 is located between the carbon box assembly 1 and the pipeline connection system 2. The fan assembly 5 is connected to both the pipeline connection system 2 and the catalytic combustion device 4.
[0027] The activated carbon box assembly 1 includes at least one activated carbon box body 11, which is provided with a first inspection door 12, a second inspection door 13, and a dust collector connecting pipe 14. The first inspection door 12 is located at the front of the activated carbon box body 11 and is used for replacing the lower activated carbon and cleaning and repairing the box. The second inspection door 13 is located at the upper part of the activated carbon box body 11 and is used for replacing the upper activated carbon. The dust collector connecting pipe 14 is located at the top of the activated carbon box body 11 and is used to connect a dust collector.
[0028] The catalytic combustion device 4 includes a catalytic combustion furnace 41 and a chimney 42. The chimney 42 is located above the catalytic combustion furnace 41, and one end of the chimney 42 is connected to the pipeline connection system 2. The pipeline connection system 2 includes a clean gas pipeline 21 and a desorption pipeline 22. One end of the clean gas pipeline 21 is connected to the outlet of the carbon box body 11, and the other end is connected to the fan assembly 5. One end of the desorption pipeline 22 is connected to the carbon box body 11 through a switching valve 3, and the other end is connected to the chimney 42. The system operating state is switched by the switching valve 3, and the corresponding box body is switched from the adsorption state to the desorption state. The desorption function is achieved by changing the airflow direction through the movement of the valve plate.
[0029] The fan assembly 5 includes a desorption fan 51 and a fan motor unit 52. The fan motor unit 52 is connected to the desorption fan 51 and drives the desorption fan 51 to operate. The inlet of the desorption fan 51 is connected to the outlet of the clean gas pipeline 21 and the outlet of the catalytic combustion furnace 41, respectively. The outlet of the desorption fan 51 is connected to the chimney 42, and a silencer is provided above the outlet of the desorption fan 51. The fan assembly 5 is mounted on a platform 7, and a rain shelter 8 is provided above the platform 7.
[0030] The intelligent control system 6 includes an intelligent control module, an exhaust concentration monitoring module, a carbon box differential pressure monitoring module, a carbon box temperature monitoring module, a catalytic furnace temperature monitoring module, a main fan control module, a cooling control module, a supplementary cooling valve control module, and an audible and visual alarm. The exhaust concentration monitoring module, carbon box differential pressure monitoring module, carbon box temperature monitoring module, and catalytic furnace temperature monitoring module monitor the entire device. Once a value exceeds a preset value, the intelligent control module receives a signal, activates the audible and visual alarm, and intelligently intervenes through the main fan control module, cooling control module, or supplementary cooling valve control module. Through a self-developed intelligent energy-saving waste gas treatment control system, the system monitors the waste gas concentration values at the front and rear ends of the treatment equipment in real time and analyzes the concentration fluctuations in the background. The desorption system is automatically activated only when the data exceeds the standard, achieving energy-saving operation. The dust removal control method adopts timed, constant pressure, and differential pressure control (which can be switched), and has automatic and manual operation functions.
[0031] During use, the exhaust gas is sent into the carbon box body 11 through the desorption pipe 22 and is adsorbed by activated carbon. The clean gas after adsorption is connected to the fan inlet through the clean gas pipe 21 and is sent by the fan to subsequent treatment or directly discharged in compliance with standards.
[0032] As time progresses, when the activated carbon approaches saturation and can no longer meet the adsorption requirements, the intelligent control system 6 monitors the concentration of exhaust gas at both the front and rear ends in real time and automatically activates the desorption system. Since this system performs offline desorption, the desorption process does not affect normal adsorption operations. The nearly saturated carbon box is switched to desorption mode via the switching valve 3.
[0033] The catalytic combustion device 4 is equipped with a heating chamber. When the heating device is activated, the desorption fan 51 provides power to circulate the gas inside. When the heat source reaches the volatilization point of the organic matter, the organic matter separates from the activated carbon and enters the catalytic chamber for catalytic decomposition, generating carbon dioxide and water, while releasing heat. Utilizing the released heat, the gas re-enters the adsorption bed for desorption. At this point, the heating device completely stops working, and the organic waste gas maintains its self-reaction within the catalytic combustion chamber, circulating until the organic matter is completely separated from the activated carbon and decomposed in the catalytic chamber, thus regenerating the activated carbon. After desorption, the carbon box continues to enter the adsorption state, while the next carbon box is switched for the desorption process. This process is repeated, enabling the entire system to operate continuously without interruption.
[0034] When the exhaust concentration is too high or the pressure difference in the carbon box is too large, the system automatically connects to the main fan control module through the intelligent control module to adjust the speed to maintain normal operation. At the same time, it will sound and light alarms and generate alarm records to remind operators to perform regular maintenance.
[0035] When the temperature of the charcoal box exceeds the set value, the system automatically connects to the cooling control module through the intelligent control module and controls the temperature through means such as valve opening adjustment. At the same time, it will sound and light alarms and generate alarm records to remind operators to perform regular maintenance.
[0036] When the temperature of the catalytic furnace is too high, the system automatically connects to the cooling air valve control module through the intelligent control module, and replenishes fresh air to the catalytic furnace system through the cooling air valve, effectively controlling the temperature of the catalytic bed and preventing the temperature of the catalytic bed from becoming too high. At the same time, an audible and visual alarm is triggered and an alarm record is generated to remind the operator to perform regular maintenance.
[0037] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.
[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
