Description

Technical Field

[0001] The present invention relates to environmental protection engineering and automated intelligent equipment technology, and in particular to a flue gas bag dust removal system and method based on automated control. The present invention realizes precise control of the entire process of flue gas dust removal treatment by integrating advanced automated control technology and environmental monitoring technology, thereby achieving the purpose of improving flue gas dust removal efficiency, reducing system energy consumption, reducing secondary pollution, and enhancing system stability. Background Art

[0002] With the rapid development of industry, the problem of flue gas emission is becoming increasingly serious. Harmful substances such as sulfides and nitrogen oxides contained in flue gas exist in the atmosphere in the form of particles and dust, causing serious pollution to the environment and seriously affecting human health and the ecological balance of the land. Therefore, flue gas dust removal is an important task in the field of environmental protection. Its purpose is to remove harmful particles and dust such as sulfides and nitrogen oxides in flue gas, reduce pollution to the atmospheric environment and harm to humans themselves.

[0003] In the prior art, conventional flue gas dust removal equipment usually uses ordinary bag dust collectors, which are dry dust removal devices suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0004] However, the bag dust removal system has problems such as low control accuracy, slow response speed, and low degree of automation, which leads to low dust removal efficiency, high energy consumption, and high manpower demand. At the same time, the control process of the bag dust removal system is cumbersome, and there is no closed-loop feedback in the control process, resulting in dust removal effect not meeting expectations.

[0005] Therefore, the research and application of flue gas bag dust removal system technology based on automatic control is of great significance and value. Summary of the invention

Each module is described in detail below.

[0041] The power configuration module provides safe and stable current for each module of the entire system. When a module fails, it can accurately and quickly cut off the power supply circuit and transmit the fault signal to the data acquisition module.

[0042] The environmental monitoring module is composed of a variety of terminal detection instruments, which are responsible for monitoring various parameters of the flue gas.

[0048] See attached Figure 3 , based on the automatic control of the bag dust removal system, the control process of this system includes multiple steps, each step is described in detail below:

[0049] After the hot debugging of the automatic control bag dust removal system is normal, set the system to automatic mode;

[0050] According to the operator's habits and actual working conditions, select the dust removal cycle mode, which is divided into timing mode, fixed resistance mode, and setting target mode;

[0051] When the timing mode is selected, the cycle interval can be set manually, or intelligent control can be selected. The intelligent control module analyzes the optimal dust removal cycle interval through the inlet and outlet dust ratio and other real-time parameters;

[0052] When the fixed resistance mode is selected, the resistance value can be set manually, or intelligent control can be selected. The intelligent control module analyzes the optimal dust removal cycle resistance value through the inlet and outlet dust ratio and other real-time parameters. The resistance value is the difference between the inlet and outlet pressures of the dust removal system.

[0053] When the dust removal target mode is selected, the dust removal target value can be set manually, or intelligent control can be selected. The intelligent control module analyzes the historical set values ​​and calculates the best dust removal target value for the real-time working conditions. The dust removal target value refers to the dust concentration of the outlet flue gas.

[0054] When the cycle interval is reached, the resistance is too large, or the dust removal target is not achieved, the dust cleaning command is triggered;

[0055] Close the 1# offline valve of chamber 1 to separate the spray chamber from the middle box, and feed back the closed position signal of the offline valve to the data acquisition module; the data analysis module determines whether the offline valve is completely closed. If not, the data is transmitted to the fault warning module; if it is closed, the spray cleaning instruction of the pulse valve of chamber 1 is triggered;

[0056] The two pulse valves in chamber 1# spray and clean dust in sequence. The pulse valve interval can be freely set by human intervention or intelligently controlled according to the current working conditions.

[0057] After the two pulse valves are sprayed and cleaned, open the 1# offline valve to connect the spray chamber and the middle box, and feed back the offline valve opening signal to the data acquisition module; the data analysis module determines whether the offline valve is fully opened. If not, the data is transmitted to the fault warning module; if it is opened, the chamber interval timer is triggered;

[0058] The compartment interval timer can be freely set by human intervention, or it can be intelligently controlled according to the current working conditions;

[0059] When the chamber interval timing is up, the 2# chamber 2# offline valve is triggered to close, which is used to separate the spray chamber and the middle box, and the offline valve's closed position signal is fed back to the data acquisition module; the data analysis module determines whether the offline valve is completely closed. If not, the data is transmitted to the fault warning module; if it is closed, the 2# chamber pulse valve spray cleaning instruction is triggered.

[0060] The two pulse valves in the 2# chamber spray and clean the dust in sequence. The pulse valve interval can be freely set by human intervention or intelligently controlled according to the current working conditions.

[0061] After the two pulse valves are used for spray cleaning, open the 2# offline valve to connect the spray chamber and the middle box, and feed back the offline valve's opening signal to the data acquisition module; the data analysis module determines whether the offline valve is fully opened. If not, the data is transmitted to the fault warning module; if it is opened, the spray cleaning and dust removal are completed, and the dust removal cycle mode is determined to enter the next cycle.

[0062] In the timing mode, the cycle interval is adjustable, generally 0-120 minutes. The cycle interval refers to the timer starting from the completion of the last chamber spraying, and the next spraying and dust removal cycle is triggered after the timing ends;

[0063] In the fixed resistance mode, the resistance value is adjustable, generally 0-1500Pa. The fixed resistance value refers to the difference between the inlet pressure and the outlet pressure of the dust collector. When the actual working resistance value is greater than the fixed resistance value, the spray dust removal cycle is triggered.

[0064] In the dust removal target mode, the dust removal target is adjustable, generally 0-10mg. The dust removal target refers to the dust concentration at the dust removal outlet. When the dust concentration value at the dust removal outlet is greater than the dust removal target value, the spray dust removal cycle is triggered.

[0065] The pulse valve blowing time is adjustable, generally 0-500MS. The pulse valve blowing time refers to the time consumed by a pulse valve to open and close. The pulse valve cleaning interval is adjustable, generally 0-50S. The cleaning interval refers to the time interval from the completion of one pulse valve action to the action of the next pulse valve. The pulse valve actions are cyclical in sequence.

[0066] The fault warning module receives abnormal equipment signals, generates fault records after secondary processing, and displays them on the human-computer interaction interface.
