Description

Technical Field

[0001] The utility model relates to the technical field of electric dust collectors, in particular to the technical field of emergency dust removal devices. Background Art

[0002] The electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate smoke from the flue gas emitted by coal-fired or oil-fired boilers, thereby significantly reducing the amount of smoke discharged into the atmosphere. It is an important environmental protection equipment for improving environmental pollution and improving air quality.

[0003] When the existing electric bag dust collector is operating normally in the ash conveying system, the ash accumulation height is below the position of the first-level material meter and will not trigger the alarm of the first-level material meter. However, when the ash conveying system fails and the ash accumulated in the ash hopper cannot be discharged in time, the ash level will rise to the position where the first-level material meter is installed and trigger its alarm. At this time, it is necessary to urgently check the ash conveying system failure, ensure smooth ash conveying as soon as possible, and reduce the ash level in the ash hopper to below the installation position of the first-level material meter to ensure the safe operation of the dust collector.

[0004] The prior art has the following defects:

[0005] 1. When the ash conveying system fails, it over-relies on the alarm of the primary material meter. If the primary material meter itself fails at this time, it is easy to cause the fault warning to be delayed, a large amount of ash will accumulate in the ash hopper, and the dust collector will have great safety hazards;

[0006] 2. When the ash conveying system fails, the first-level material meter will give a normal warning, but if the ash conveying failure is not promptly checked, the actual ash accumulation in the ash hopper cannot be known;

[0007] 3. When the first-level material meter issues an early warning for a long time and the problem with the ash conveying system has not been resolved, emergency ash discharge is required. However, since the actual ash accumulation in the ash hopper is unknown, the time for emergency ash discharge cannot be reasonably determined. Utility Model Content

[0008] The purpose of the utility model is to solve the problems in the prior art and to provide a device for real-time monitoring of high material level and emergency ash discharge, which can solve the above problems.

[0009] To achieve the above-mentioned purpose, the utility model proposes a device for real-time monitoring of high material levels and emergency ash discharge, comprising an electric bag dust collector, an emergency ash discharge mechanism and a monitoring mechanism. A plurality of ash hoppers are arranged below the electric bag dust collector, and a first-level material meter is arranged in the ash hopper. The emergency ash discharge mechanism comprises an emergency ash discharge pipe, an emergency ash discharge valve, an ash discharge hose and a positive / negative pressure ash suction machine. The ash hopper is connected to the emergency ash discharge pipe, and an emergency ash discharge valve is arranged on the emergency ash discharge pipe. The emergency ash discharge pipe is connected to the ash discharge hose, and the ash discharge hose is connected to the positive / negative pressure ash suction machine. A monitoring mechanism is arranged above the ash hopper, and the monitoring mechanism comprises an upward-looking camera and a downward-looking camera.

[0010] Preferably, a fixing rod and a camera protection sleeve are provided above the ash hopper, the upward-looking camera and the downward-looking camera are fixed on the fixing rod, the camera protection sleeve or the fixing rod is connected to a rotating motor, the camera protection sleeve is sleeved on the outside of the upward-looking camera and the downward-looking camera, the camera protection sleeve is provided with an upper opening at the position of the upward-looking camera, and the camera protection sleeve is provided with a lower opening at the position of the downward-looking camera.

[0011] Preferably, the back sides of the upward-looking camera and the downward-looking camera are both provided with hole-blocking sleeves.

[0012] Preferably, sealing rings are provided on both sides of the upward-looking camera and the downward-looking camera.

[0013] The beneficial effects of the utility model are as follows: the utility model sets a monitoring mechanism and an emergency ash discharge mechanism. When the first-level material meter gives a normal warning, the ash conveying problem should be solved immediately. If the problem cannot be solved in time, the ash accumulation status of the ash hopper can be intuitively seen by adjusting the downward-looking camera, so as to determine whether it is necessary to open the emergency ash discharge pipe valve, and clean up the excess ash in the ash hopper through a positive / negative pressure ash suction vehicle to avoid safety accidents of the electric bag dust collector; the utility model can intuitively see the operation status of the internal equipment of the dust collector through the upward-looking camera, monitor the internal operation status of the dust collector in real time, and deal with the conditions of the internal equipment of the dust collector in time to avoid safety hazards.
