in use Wet electrostatic precipitator In the process of, we may encounter problems of one kind or another. If we don't know how to solve them, we will be at a loss. that Wet electrostatic precipitator What is the reason for the failure of the device? The following is a brief analysis for you.

(1) Electrical fault causes: electrical components are damaged, corona rod is improperly adjusted, wall porcelain bushing and post insulator are damaged, etc.

Electrical components are damaged, such as fuse breakdown of high-voltage silicon rectifier tube or thyristor damage can lead to power damage; If the milliammeter is damaged or the transformer fails, the fault type (3) phenomenon will appear.

(2) If the nickel chromium alloy wire is not used, the corona electrode will rust and break off after a short time of use. The density of corona wire is uneven, the stress is uneven, and the overload of corona electrode will also lead to the fracture of corona electrode. Improper installation of corona rod, deviation of sedimentation tube center, excessive scaling, etc. will cause frequent flashover of electric field, and even cause operation interruption.

(3) If the mechanical properties of through wall porcelain bushing and post insulator cannot well withstand the pull of upper and lower hangers, the insulator will crack. The insulator box temperature control is unreasonable, the temperature is too low or changes violently, which will also lead to the cracking of insulators. Excessive scaling on insulator surface will also lead to insulator cracking. The final result is that electric field grounding occurs, esp operation is interrupted, and faults (2) and (4) occur.

(2) The reasons for failure caused by unstable operation are: improper temperature control of insulator box; The gas separation plate is blocked and the precipitation is too thick; Improper adjustment of water film; The oxygen content in the system exceeds the standard.

① Insufficient steam pressure and blocked steam pipeline may cause the insulator box temperature to be too low. In the long run, the insulator surface temperature is too low, and tar and dust particles accumulate, leading to electric field short circuit. During operation, if the temperature of insulator box rises too fast or changes violently, the insulator will crack.

② If the operation cannot be conducted intermittently according to the requirements, the accumulation of tar deposits on the pipe wall is difficult to get a more thorough cleaning. The accumulation of tar deposits over a long period of time will not only cause too much resistance to equipment operation, but also lead to the destruction of the electric field.

③ During maintenance, the water film is not adjusted as required, the water film is uneven or not thick enough, and failure (4) will occur when the water film is put into operation. This may also happen if the water film is damaged during operation.

④ Electrostatic precipitator The reason for explosion is that the oxygen content in the gas exceeds the standard, forming mixed explosive gas in the equipment, reaching the explosion limit, and exploding when encountering electric spark.
