Description

Technical Field

[0001] This invention relates to the technical field of ash hopper heating, and in particular to the technical field of ash hopper heating control systems. Background Technology

[0002] The heating device in the ash hopper of an electrostatic precipitator is a key component to ensure smooth dust discharge. Its core function is to maintain the temperature of the ash hopper to prevent dust from clumping or sticking due to moisture or low temperature, thus avoiding ash hopper blockage and ash discharge system failure.

[0003] Existing ash hopper heating control systems are generally linked to temperature sensors, which are installed on or inside the ash hopper wall to monitor the temperature in real time. The intelligent controller sets the target temperature and automatically adjusts the heating power based on sensor feedback. This control method is greatly affected by the ambient temperature and the installation location of the temperature sensor. During use, the electric heating device will be frequently activated. Even when the ambient temperature is low and the ash is not damp, the electric heating device will continue to work, resulting in energy waste. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a linkage system between a hygrometer and a plate electric heater, which can solve the above problems.

[0005] To achieve the above objectives, this invention proposes a linkage system of a hygrometer and a plate-type electric heater, including an ash hopper, an electric heating module, a humidity detection module, and a control center. The electric heating module is distributed around the outer wall of the ash hopper, and the humidity detection module is provided on the inner wall of the ash hopper. The humidity detection module is used to detect the moisture content of the ash falling into the ash hopper. Both the humidity detection module and the electric heating module are connected to the control center. When the humidity detected by the humidity detection module is greater than a set threshold, the control center controls the electric heating module to heat the ash.

[0006] Preferably, the electric heating module includes several sets of electric heaters, and the control center includes a data analysis module and a control module. The data analysis module determines the corresponding level based on the humidity detected by the humidity detection module, and the control module controls different numbers of electric heaters to work according to different levels.

[0007] Preferably, the electric heater is a plate electric heater.

[0008] Preferably, the linkage system between the hygrometer and the plate electric heating can switch between manual and automatic modes.

[0009] As a preferred option, the working steps of the dynamic mode are as follows: S1. The humidity detection module detects the dryness and humidity value RH of the ash falling into the ash hopper. The data analysis module compares RH with K. If RH≤K, execute S5; if RH>K, execute S2. S2. The data analysis module calculates the gear position based on RH, and the control module controls the corresponding number of electric heaters to work based on the gear position obtained by the data analysis module. S3. After a delay of T1 min, the humidity is detected again. The data analysis module compares the detected RH with the previously collected RH to determine whether the RH has decreased. If yes, S4a is executed; otherwise, S4b is executed. S4a. Reduce the number of heating groups of the electric heater and determine whether the number of heating groups is 0. If yes, proceed to S5; otherwise, return to step S3. S4b: Increase the number of heating groups of the electric heater and determine whether the number of heating groups is 4. If yes, issue an alarm signal; otherwise, execute S3. S5. Stop heating, delay for T2 minutes, then check the humidity again and execute S1.

[0010] Preferably, the electric heater has four sets, and the data analysis module has four settings. The specific steps of S2 are as follows: When K < RH ≤ K1, the data analysis module outputs the first gear signal to the control module, and the control module starts a set of electric heaters to heat. When K1 < RH ≤ K2, the data analysis module outputs the second gear signal to the control module, and the control module starts the two sets of electric heaters to heat. When K2<RH≤K3, the data analysis module outputs the signal for the third gear to the control module, and the control module starts the three sets of electric heaters to heat. When RH > K3, the data analysis module outputs the signal for the fourth gear to the control module, and the control module starts the four sets of electric heaters to heat. Where K is the critical dryness value, K1 is the low humidity value, K2 is the medium humidity value, and K3 is the high humidity value.

[0011] As a preferred option, K, K1, K2, K3, T1, and T2 are set by the staff themselves.

[0012] As a preferred embodiment, in S4b, after receiving an alarm signal, the host computer alarms. The system determines whether the alarm signal from the host computer has been promptly acknowledged. If yes, the alarm is canceled and S1 is executed. If not, an alarm message is sent to the mobile terminal of the corresponding staff member via the Internet of Things, and it is determined whether the alarm message from the mobile terminal has been promptly acknowledged. If yes, the alarm is canceled and S1 is executed. If not, the host computer alarms again.

[0013] As a preferred method, the working steps in manual mode are as follows: a. Staff can manually select the number of heating groups for the electric heater via a host computer. b. After a delay of T3 minutes, determine whether RH ≤ K. If yes, repeat this step; otherwise, the host computer will issue an alarm. The beneficial effects of this invention are as follows: By linking the heating control system of the ash hopper with the humidity, the hygrometer can better reflect the moisture level of the ash in the ash hopper. When the ambient temperature is low but the dryness of the ash in the ash hopper meets the standard, the heating device will not be activated, which can reduce energy consumption. Different stages of drying require different amounts of heat. The system can control the activation of different numbers of electric heaters through gear settings, which can avoid energy waste caused by running at full power throughout the process and achieve energy saving effect.

[0014] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

The electric heating module is distributed around the outer wall of the ash hopper, and the humidity detection module is installed on the inner wall of the ash hopper. The humidity detection module is used to detect the moisture content of the ash falling into the ash hopper. Both the humidity detection module and the electric heating module are connected to the control center. When the humidity detected by the humidity detection module is greater than a set threshold, the control center controls the electric heating module to heat the ash.

[0017] The electric heating module includes several sets of electric heaters, and the control center includes a data analysis module and a control module. The data analysis module determines the corresponding level based on the humidity detected by the humidity detection module, and the control module controls different numbers of electric heaters to work according to different levels.

[0018] The electric heater is a plate-type electric heater.

[0019] The linkage system between the hygrometer and the plate electric heater can switch between manual and automatic modes.

[0020] The automatic mode works as follows: S1. The humidity detection module detects the dryness and humidity value RH of the ash falling into the ash hopper. The data analysis module compares RH with K. If RH≤K, execute S5; if RH>K, execute S2. S2. The data analysis module calculates the gear position based on RH, and the control module controls the corresponding number of electric heaters to work based on the gear position obtained by the data analysis module. S3. After a 20-minute delay, detect the humidity again. Compare the detected RH with the previously collected RH using the data analysis module to determine if the RH has decreased. If yes, execute S4a; otherwise, execute S4b. S4a. Reduce the number of heating groups of the electric heater and determine whether the number of heating groups is 0. If yes, proceed to S5; otherwise, return to step S3. S4b: Increase the number of heating groups of the electric heater and determine whether the number of heating groups is 4. If yes, issue an alarm signal; otherwise, execute S3. Upon receiving an alarm signal, the host computer triggers an alarm. The system determines whether the alarm signal from the host computer is confirmed within 30 minutes. If yes, the alarm is canceled and S1 is executed. If not, an alarm message is sent to the mobile terminal of the relevant staff member via the Internet of Things, and the system determines whether the alarm message from the mobile terminal is confirmed in a timely manner. If yes, the alarm is canceled and S1 is executed. If not, the host computer triggers an alarm again. S5. Stop heating, delay for 30 minutes and then check the humidity again, then execute S1.

[0021] The electric heater has four sets, and the data analysis module has four settings. The specific steps of S2 are as follows: When K < RH ≤ K1, the data analysis module outputs the first gear signal to the control module, and the control module starts a set of electric heaters to heat. When K1 < RH ≤ K2, the data analysis module outputs the second gear signal to the control module, and the control module starts the two sets of electric heaters to heat. When K2<RH≤K3, the data analysis module outputs the signal for the third gear to the control module, and the control module starts the three sets of electric heaters to heat. When RH > K3, the data analysis module outputs the signal for the fourth gear to the control module, and the control module starts the four sets of electric heaters to heat. Where K is the critical dryness value, K1 is the low humidity value, K2 is the medium humidity value, and K3 is the high humidity value.

[0022] The steps for working in manual mode are as follows: a. Staff can manually select the number of heating groups for the electric heater via a host computer. b. After a delay of T3 minutes, determine whether RH is ≤ K. If yes, repeat this step; otherwise, the host computer will issue an alarm.

[0023] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
