Description

Technical Field

[0001] The present invention relates to the technical field of combustion type waste gas treatment, and in particular to a combustion gas flow control method and device for a combustion type waste gas treatment device. Background Art

[0002] In actual use, combustion-type exhaust gas treatment systems are operated in a two-stage configuration. When one unit fails, all the gas it needs to process is switched to the backup unit, causing a sudden increase in the amount of gas the backup unit needs to handle, impacting its efficiency. Currently, common combustion-type exhaust gas treatment systems control the combustion gas flow rate using empirically set fixed-flow combustion and an upgraded, multi-stage flow-set combustion method, which uses two or three fixed flow rates to maintain high temperatures for the reactant gases. Multi-stage combustion offers advantages over fixed-flow combustion because it can adjust the initial set flow rate to raise or lower the temperature within the reaction chamber when increased intake air volume or different intake air types require higher temperatures. Furthermore, with multi-stage combustion, the timing of changes in combustion flow rate requires communication with upstream equipment, with the control system using these signals to adjust the fixed combustion flow rate. However, both fixed-flow and multi-stage combustion methods are essentially fixed combustion, with combustion flow rates set based on prior design experience. The treatment efficiency of the equipment cannot be reflected in real time. Therefore, the energy provided by a certain fixed combustion flow rate may not be able to completely treat the gas entering the exhaust gas treatment equipment, affecting the equipment's treatment efficiency. Even if the energy provided by this combustion flow rate meets the equipment's treatment efficiency requirements, it may still result in excess energy, causing energy waste. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] Figure 1 A flow chart showing a method for controlling the flow of combustion gas in a combustion type exhaust gas treatment device according to the present invention is shown. Figure 1 , the method comprising:

[0035] 11. Obtaining the actual treatment efficiency of the combustion-type exhaust gas treatment device and the actual exhaust gas flow rate input into the combustion-type exhaust gas treatment device;

[0036] 12. Determine the flow difference and flow ratio based on the actual exhaust gas flow and the standard exhaust gas flow;

[0037] 13. When it is determined that the flow difference falls within the preset flow range, the adjusted gas flow is determined based on the flow ratio and the preset standard gas flow, and when the actual processing efficiency and the preset standard processing efficiency meet the preset conditions, the gas is input into the combustion exhaust gas treatment device according to the preset PID flow control mode.

[0038] Regarding steps 11 to 13, it should be noted that in the present invention, an online gas sampler is added to the tail end of the exhaust gas treatment device to monitor the actual treatment efficiency of the exhaust gas treatment device in real time by analyzing the sampled data. A flow meter is added to the exhaust gas inlet of the exhaust gas treatment device to monitor changes in the exhaust gas flow rate.

[0039] In the present invention, the actual treatment efficiency of the combustion-type exhaust gas treatment device and the actual exhaust gas flow rate input into the combustion-type exhaust gas treatment device can be obtained in a periodic manner.

[0040] In the present invention, the exhaust gas treatment device is provided with a standard treatment efficiency and a standard exhaust gas flow rate entering the exhaust gas treatment device.

[0041] In the present invention, the flow rate difference is determined based on the actual exhaust gas flow rate and the standard exhaust gas flow rate. Here, the flow rate difference is an absolute value. This means that the actual exhaust gas flow rate may be greater than the standard exhaust gas flow rate, while the actual exhaust gas flow rate may be less than the standard exhaust gas flow rate.

[0042] In the present invention, the flow ratio is determined based on the actual exhaust gas flow rate and the standard exhaust gas flow rate. Here, the flow ratio is preferably (standard exhaust gas flow rate / actual exhaust gas flow rate).

[0043] In the present invention, based on the comparison between the actual exhaust gas flow rate change and the preset flow rate range, temporary regulation of the gas flow rate is performed, as well as timed and quantitative regulation of the gas flow rate, so as to achieve effective utilization of gas resources and improve the response speed and stability of equipment control.

[0044] In the present invention, when the flow difference falls within a preset flow range, reasonable planning and calculation are performed according to the above-mentioned flow ratio and standard gas flow to determine the adjusted gas flow, and gas is input into the exhaust gas treatment device according to the adjusted gas flow to combust and treat the exhaust gas. During the gas flow adjustment process, when the actual treatment efficiency and the standard treatment efficiency obtained meet the preset conditions (i.e., under different scenarios, the actual treatment efficiency is greater than or equal to the standard treatment efficiency, or the actual treatment efficiency is equal to the standard treatment efficiency), the gas is input into the combustion-type exhaust gas treatment device according to the preset PID flow control mode, that is, according to the timed and quantitative adjustment, that is, the gas flow control mode initially set by the exhaust gas treatment device.

[0045] The present invention provides a combustion gas flow control method for a combustion-type exhaust gas treatment device. When the flow difference falls within the flow range, the adjusted gas flow is determined based on the flow ratio and the standard gas flow. When the actual treatment efficiency and the preset standard treatment efficiency meet the preset conditions, the gas is input into the combustion-type exhaust gas treatment device according to the preset PID flow control mode. The method adopts a combination of temporary regulation and timed quantitative regulation of the gas flow to achieve effective utilization of gas resources and improve the response speed and stability of equipment control.

[0046] In a further method of the above method, the main explanation is as follows: when it is determined that the flow difference falls within a preset flow range, the adjusted gas flow rate is determined based on the flow ratio and the preset standard gas flow rate, and when the actual treatment efficiency and the preset standard treatment efficiency meet the preset conditions, the gas is input into the combustion type exhaust gas treatment device according to the preset PID flow control mode.

[0047] When the flow difference falls within the preset flow range, and Q a / Q b =Q d When it is less than 1, press Determine the adjusted gas flow rate until, after n cycles, when the actual treatment efficiency is greater than or equal to the standard treatment efficiency, the gas is input into the combustion-type exhaust gas treatment device according to a preset PID flow control mode;

[0048] When the flow difference falls within the preset flow range, and Q d When it is greater than 1, press Determine the adjusted gas flow rate until after n cycles, when the actual treatment efficiency is equal to the standard treatment efficiency, and input the gas into the combustion type exhaust gas treatment device according to a preset PID flow control mode;

[0049] Among them, Q a is the standard exhaust gas flow rate, Q bis the actual exhaust gas flow rate, Q d is the flow ratio, Q1 is the standard gas flow, k1 and k2 are preset coefficients, n=0,1,2,3……

[0050] In this regard, it should be noted that in the present invention, the standard treatment efficiency that the exhaust gas treatment device needs to meet is ηs, and the actual treatment efficiency value fed back by the online gas sampler is ηp. The standard exhaust gas flow rate detected by the exhaust gas treatment device during stable operation is Q a , temporarily save this value as the initial value, the standard gas flow detected by the flow meter is Q1. The actual exhaust gas flow feedback from the flow meter is Q b .

[0051] Because the operating conditions of each exhaust gas treatment device are different, the time for the exhaust gas to travel from the air inlet to the air outlet is also different. Therefore, a periodic detection method is adopted, with the time being t, and a comparison is made every time t passes.

[0052] Assume |Q a -Q b |=Q c , because the flow rate of each air inlet is different according to the exhaust gas treatment device, the air intake volume is within the preset flow range of 100-200slm, so when Q c When Q is less than 100slm, the gas is input into the combustion exhaust gas treatment device according to the preset PID flow control mode to ensure that ηp≥ηs; when Q c When the speed is >100slm, the adjusted gas flow is determined based on the flow ratio and the standard gas flow. When the adjustment is stable, the PID flow control mode is re-engaged to ensure high processing efficiency and reduce energy consumption.

[0053] When Q c When >100slm, determine Q a / Q b =Q d When Q d <1, indicating that the gas is increasing in a positive direction. At this time, ηp<ηs, which is the processing efficiency of the fast following device to prevent the exhaust gas from being discharged without treatment and polluting the environment. At this time, the gas flow rate is adjusted to At this time, after waiting for a period of time t, the actual processing efficiency is judged. If ηp < ηs, the gas flow rate setting value Q1 / k1 (k1 can be 10) is increased every time t time passes, and the processing efficiency value is judged at the same time until ηp < ηs. After n cycles, the final adjusted gas flow rate is At this time, the fuel gas is input into the combustion-type exhaust gas treatment device according to the preset PID flow control mode.

[0054] When Q c When >100slm, determine Qa / Q b =Q d When Q d When ηp>1, it means that the gas is decreasing in a negative direction. At this time, ηp>ηs, which still meets the processing requirements of the equipment, but the amount of exhaust gas entering the equipment is reduced instantly. If the current gas flow is still used, although it can meet the processing efficiency requirements of the equipment, it actually causes a waste of combustion energy. If PID adjustment is continued, because the PID control parameters are adjustment parameters under the condition of stable exhaust gas volume, it has poor follow-up performance in the face of sudden gas volume reduction, so it is necessary to adjust the gas flow. The gas flow value is adjusted to At this time, wait for a time t to judge the current processing efficiency. If ηp>ηs, reduce the gas flow rate setting value Q1 / k2 (k2 can be 10) slm every time t time passes. After n cycles, the final adjusted gas flow rate At the same time, the treatment efficiency value is judged until ηp=ηs, at which time the fuel gas is input into the combustion exhaust gas treatment device according to the preset PID flow control mode.

[0055] In a further embodiment of the above method, when it is determined that the flow rate difference is less than or equal to a minimum value of a preset flow rate range, gas is fed into the combustion-type exhaust gas treatment device according to a preset PID flow control mode. Additionally, when the flow rate difference is greater than or equal to a maximum value of the preset flow rate range, an alarm may be issued.
