Description

Technical Field

[0001] The present invention relates to the technical field of flue gas desulfurization, and in particular to an atomizer overflow protection system, method and readable storage medium. Background Art

[0002] The SDA semi-dry desulfurization process generally uses quicklime and baking soda as desulfurizers. The desulfurizer slurry is pumped to the rotary atomizer at the top of the desulfurization tower. The atomizer wheel of the atomizer rotates at high speed to form droplets, which react with SO2 in the flue gas. The SO2 in the flue gas is absorbed and purified to form desulfurization ash products. A small amount of large-particle desulfurization ash settles to the bottom of the desulfurization tower and is discharged. Most of the desulfurization ash enters the bag filter with the flue gas through the flue pipe after the desulfurization tower for purification, removing dust and other particulate matter. The treated flue gas is then purified by the denitrification system and discharged through the chimney.

[0003] Among them, the atomizer is the core equipment in this process system. It is installed at the bottom of the volute cone bucket at the top of the desulfurization tower, and the required slurry is transported through the slurry pipeline. Due to the small space, high temperature, and large dust at the installation location of the atomizer, coupled with factors such as pipeline scouring and wear, it is very easy to cause perforation of the slurry pipeline or loosening of pipeline connection parts, causing the slurry in the slurry pipeline or the protective water in the protective water pipeline to leak and flood the bottom of the volute cone bucket, causing serious water ingress to the atomizer and damage to the internal working parts. Therefore, an overflow protection device must be installed at the volute cone bucket where the atomizer is installed.

[0004] However, the overflow protection devices currently used are either too insensitive, resulting in an overflow accident and failure of protection, causing the atomizer to be soaked in slurry and damaged; or too sensitive, resulting in a false protection operation even when there is no overflow, causing other equipment to be interlocked and stopped, directly affecting the flue gas emission indicators and causing unnecessary environmental incidents. Summary of the invention

[0005] The object of the present invention is to provide an atomizer overflow protection system, method and readable storage medium, which can accurately determine whether an atomizer overflow failure occurs in the first time and improve the reliability of the atomizer overflow protection.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an atomizer overflow protection system, including a desulfurization tower, a volute cone bucket, an atomizer, a slurry pipeline and a temperature detection unit, the volute cone bucket is arranged at the top of the desulfurization tower, the bottom end of the atomizer is provided with a mounting platform, the atomizer is arranged at the bottom end of the volute cone bucket through the mounting platform, the slurry pipeline extends from the outside of the desulfurization tower to the inside of the volute cone bucket and is connected to the atomizer, and the temperature detection unit is arranged on the mounting platform and is used to detect the temperature at the bottom end of the volute cone bucket.

[0007] Optionally, a pipe joint is provided on the mounting platform, and the slurry pipeline is connected to the internal pipeline of the atomizer through the pipe joint.

[0008] Optionally, the atomizer overflow protection system also includes a control unit, which is communicatively connected with the temperature detection unit, the atomizer and the shut-off valve on the slurry pipeline. When the temperature detected by the temperature detection unit is lower than the set temperature, a shutdown signal can be sent to the control unit, and the control unit controls the atomizer to shut down and the shut-off valve to close.

[0009] Optionally, the atomizer overflow protection system further includes an alarm unit, which is communicatively connected to the control unit, and the control unit controls the alarm unit to alarm when receiving the shutdown signal.

[0010] Optionally, the temperature detection unit includes at least two temperature sensors;

[0011] When the control unit receives the shutdown signal sent by at least two of the temperature sensors, it controls the alarm unit to alarm, and at the same time controls the atomizer to stop and controls the cut-off valve to close;

[0012] When the control unit receives only a shutdown signal sent by the temperature sensor, only the alarm unit is controlled to alarm.

[0013] Optionally, the temperature sensors are evenly distributed on the same horizontal plane of the installation platform.

[0014] Optionally, the temperature of the slurry flowing in the slurry pipe is lower than the normal ambient temperature at the bottom end of the volute cone bucket, and the set temperature is between the temperature of the slurry flowing in the slurry pipe and the normal ambient temperature at the bottom end of the volute cone bucket.

[0015] Based on the same inventive concept, the present invention also provides an atomizer overflow protection method, which uses the atomizer overflow protection system as described above to perform overflow protection on the atomizer, comprising the following steps:

[0016] When the atomizer is operating normally, the temperature at the bottom end of the volute cone bucket is detected in real time by the temperature detection unit;

[0017] When the temperature detected by the temperature detection unit is lower than the set temperature, the atomizer is controlled to stop and the slurry pipeline is cut off.

[0018] Optionally, the atomizer overflow protection system further includes an alarm unit, the temperature detection unit includes at least two temperature sensors, and when the temperatures detected by at least two of the temperature sensors are lower than a set temperature, the alarm unit is controlled to alarm, and the atomizer is controlled to stop and the slurry pipeline is cut off;

[0019] When the temperature detected by only one of the temperature sensors is lower than the set temperature, only the alarm unit is controlled to alarm.

[0020] Based on the same inventive concept, the present invention further provides a readable storage medium on which a computer program is stored. When the computer program is executed, the atomizer overflow protection method as described above can be implemented.

[0021] The atomizer overflow protection system, method and readable storage medium provided by the present invention have at least one of the following beneficial effects:

[0022] 1) Since the normal ambient temperature at the bottom of the volute cone bucket is generally greater than 50°C when the atomizer is working normally and the slurry is not leaking, while the temperature of the slurry is usually lower than 40°C, a temperature detection unit is set on the mounting platform to detect the temperature at the bottom of the volute cone bucket in real time. When the slurry leaks, it will inevitably soak the mounting platform and then submerge the temperature detection unit. At this time, the temperature detected by the temperature detection unit will drop sharply and be lower than the normal ambient temperature, so it can be judged that the slurry has leaked. At this time, the atomizer can be stopped in time and the slurry pipeline can be cut off to avoid excessive losses;

[0023] 2) By setting at least two temperature sensors, when the control unit receives the shutdown signal sent by at least two temperature sensors, it determines that there is slurry leakage, that is, an overflow event has occurred. At this time, the alarm unit alarms, and immediately controls the atomizer to shut down and control the shut-off valve to close. When the control unit only receives the shutdown signal sent by one temperature sensor, the alarm unit is controlled to alarm, reminding manual confirmation and judgment to prevent the atomizer from making unnecessary malfunctions, so that it can accurately determine whether the atomizer has an overflow failure at the first time, effectively avoid the occurrence of missed detection events, and greatly improve the reliability of the atomizer overflow protection;

[0024] 3) The whole structure is simple, easy to operate, easy to maintain, highly reliable, and does not require daily maintenance, which reduces the safety risks of manual online maintenance of equipment and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Please refer to Figure 1The present embodiment provides an atomizer overflow protection system, including a desulfurization tower 1, a volute cone bucket 2, an atomizer 3, a slurry pipeline 4 and a temperature detection unit 5. The volute cone bucket 2 is arranged at the top of the desulfurization tower 1, and a mounting platform 6 is arranged at the bottom end of the atomizer 3. The atomizer 3 is arranged at the bottom end of the volute cone bucket 2 through the mounting platform 6. The slurry pipeline 4 extends from the outside of the desulfurization tower 1 to the inside of the volute cone bucket 2 and is connected to the atomizer 3. The temperature detection unit 5 is arranged on the mounting platform 6 and is used to detect the temperature at the bottom end of the volute cone bucket 2.

[0033] The working principle of the present invention is as follows:

[0034] Since the normal ambient temperature at the bottom of the volute cone bucket 2 is generally greater than 50°C when the atomizer 3 is working normally and the slurry is not leaking, and the temperature of the slurry is usually lower than 40°C, a temperature detection unit 5 is provided on the mounting platform 6 to detect the temperature at the bottom of the volute cone bucket 2 in real time. When the slurry leaks, it will inevitably soak the mounting platform 6 and then submerge the temperature detection unit 5. At this time, the temperature detected by the temperature detection unit 5 will drop sharply and be lower than the normal ambient temperature, thereby judging that the slurry has leaked. At this time, the atomizer 3 can be shut down in time, and the slurry pipeline 4 can be cut off to avoid excessive losses.

[0035] In this embodiment, a pipe joint is provided on the mounting platform 6, and the slurry pipe 4 is connected to the internal pipe of the atomizer 3 through the pipe joint. It should be noted that in addition to the slurry pipe 4, a protective water pipe such as a flushing pipe, a cooling water pipe, etc. is generally provided. These pipes are generally connected to the internal pipe of the atomizer 3 through the pipe joint provided on the mounting platform 6. If these pipes leak, the atomizer 3 will also be damaged by water inlet. At this time, the temperature detection unit 5 can also detect whether a leak occurs at the same time, and the present invention will not list them one by one.

[0036] In this embodiment, the volute cone bucket 2 is arranged at the top of the desulfurization tower 1, and its diameter gradually decreases from top to bottom. The interior of the volute cone bucket 2 is a cavity, which can be used to set up equipment such as a motor, and the motor is used to drive the atomizer 3 to work.

[0037] Preferably, the atomizer overflow protection system further includes a control unit 7, which is in communication connection with the temperature detection unit 5, the atomizer 3 and the cut-off valve on the slurry pipeline 4. When the temperature detected by the temperature detection unit 5 is lower than the set temperature, a shutdown signal can be sent to the control unit 7, and the control unit 7 controls the atomizer 3 to shut down and close the cut-off valve. In this embodiment, when the temperature detected by the temperature detection unit 5 is lower than the set temperature, a shutdown signal is sent to the control unit 7, and after receiving the shutdown signal, the control unit 7 immediately controls the atomizer 3 to shut down and close the cut-off valve to prevent the slurry from continuing to be transported and leaking, causing the accident to expand.

[0038] In this embodiment, the control unit 7 includes but is not limited to a PLC or a single chip microcomputer.

[0039] In this embodiment, the temperature of the slurry flowing in the slurry pipe 4 is lower than the normal ambient temperature at the bottom of the volute cone bucket 2. The set temperature is, for example, between the temperature of the slurry flowing in the slurry pipe 4 and the normal ambient temperature at the bottom of the volute cone bucket 2. The set temperature can be set artificially, and the present invention is not limited to this. For example, the set temperature is 45°C.

[0040] Furthermore, the atomizer overflow protection system further includes an alarm unit 8, which is in communication with the control unit 7. When the control unit 7 receives a shutdown signal, it controls the alarm unit 8 to alarm, and the alarm unit 8 sends an alarm signal to remind the operator, so that the operator can handle it in time. The alarm unit 8 includes but is not limited to a sound alarm, a light alarm, or a sound and light alarm.

[0041] Furthermore, the temperature detection unit 5 includes at least two temperature sensors;

[0042] When the control unit 7 receives the shutdown signal sent by at least two temperature sensors, it controls the alarm unit 8 to alarm, and at the same time controls the atomizer 3 to stop and the cut-off valve to close;

[0043] When the control unit 7 receives the shutdown signal sent by only one temperature sensor, it only controls the alarm unit 8 to alarm.

[0044] By setting at least two temperature sensors, when the control unit 7 receives the shutdown signal sent by at least two temperature sensors, it is determined that there is slurry leakage, that is, an overflow event has occurred. At this time, the alarm unit 8 alarms, and immediately controls the atomizer 3 to shut down and control the shut-off valve to close. When the control unit 7 only receives the shutdown signal sent by one temperature sensor, the alarm unit 8 is controlled to alarm, reminding manual confirmation and judgment to prevent the atomizer 3 from producing unnecessary malfunctions, so that it can accurately determine whether the atomizer 3 has an overflow failure at the first time.

[0045] Preferably, the alarm unit 8 can send out at least two different alarm signals, for example, when the control unit 7 receives a shutdown signal sent by at least two temperature sensors, the alarm unit 8 sends out an audible and visual alarm, and when the control unit 7 receives a shutdown signal sent by only one temperature sensor, the alarm unit 8 sends out an audible alarm; or, when the control unit 7 receives a shutdown signal sent by at least two temperature sensors, the alarm unit 8 sends out an audible + red light alarm, and when the control unit 7 receives a shutdown signal sent by only one temperature sensor, the alarm unit 8 sends out an audible + yellow light alarm, and the present invention does not limit this. Therefore, as long as the control unit 7 receives a shutdown signal, an alarm will be issued, and manual judgment at this time can effectively avoid the occurrence of missed detection events, greatly improving the reliability of the atomizer overflow protection, and no daily maintenance is required, reducing the safety risk of manual online maintenance of the equipment.

[0046] It should be noted that the temperature sensor, control unit 7 and alarm unit 8 mentioned in the present invention are all prior art. The present invention does not involve the improvement of computer programs, but only involves the combination of existing modules. At the same time, technicians in this field should know how to specifically implement the communication connection between the control unit 7 and other devices.

[0047] Preferably, the temperature sensors are evenly distributed on the same horizontal plane of the mounting platform 6 to improve the accuracy of the temperature detection result. In this embodiment, there are three temperature sensors and they are symmetrically arranged at an angle of 120° with respect to each other, but the present invention is not limited thereto.

[0048] Based on the same inventive concept, an embodiment of the present invention further provides an atomizer overflow protection method, which uses the above atomizer overflow protection system to perform overflow protection on the atomizer 3, comprising the following steps:

[0049] S1. When the atomizer 3 is working normally, the temperature at the bottom end of the volute cone bucket 2 is detected in real time by the temperature detection unit 5;

[0050] S2. When the temperature detected by the temperature detection unit 5 is lower than the set temperature, the atomizer 3 is controlled to stop and the slurry pipeline 4 is cut off.

[0051] Preferably, the atomizer overflow protection system further includes an alarm unit 8, and the temperature detection unit 5 includes at least two temperature sensors. When the temperatures detected by at least two temperature sensors are lower than the set temperature, the alarm unit 8 is controlled to alarm, and the atomizer 3 is controlled to stop and the slurry pipeline 4 is cut off.

[0052] When the temperature detected by only one temperature sensor is lower than the set temperature, only the alarm unit 8 is controlled to alarm.
