Wind speed difference is little, then and electrical signal differential is also little, and if causing gas can not since gas cleaning plant is damaged
Normal discharge, then the wind speed that may result in gas outlet diminishes, and the electric signal that air velocity transducer produces at this also can be smaller, this
It will result in differing greatly for electric signal at two in the case of kind.CPU controls are transmitted separately in the electric signal of two groups of air velocity transducers
When in device processed, two groups of data can be analyzed on the CPU control chips in cpu controller, if the difference of two groups of data is big
It is small to warning part output control signal warning part to be made to send warning letter beyond set operation threshold, cpu controller
Breath, prompts operating personnel to close in time and is overhauled, and continues to take out into gas cleaning plant while directly stopping aspiration pump
Exhaust gas is taken, avoids causing internal further destruction as far as possible.On the contrary then not output control signal, equipment normal operation.On
State technical solution and not only solve the utility model well and propose technical problems to be solved, and its structure is relatively easy,
It is easy to actual processing and implementation.
The technical program is further arranged to：Fixing groove, CPU controls are offered on the shell body of the gas cleaning plant
Device is fixedly connected in fixing groove.
Pass through above-mentioned technical proposal：The placement of cpu controller can be solved the problems, such as well by said structure, due to phase
When in being directly embedded in the shell body of gas cleaning plant, ensure that the clean and tidy of gas cleaning plant outer wall.
The technical program is further arranged to：Protection is hinged with the notch of the fixing groove to renovate.
Pass through above-mentioned technical proposal：Renovate and the cpu controller being connected in fixing groove can be played very well by protection
Good protective effect, and being renovated due to the protection is hinged at the notch of fixing groove, is directly turned over when observing inner case
Open, be also convenient for the maintenance of operating personnel
The technical program is further arranged to：The warning part is warning lamp, is fixedly connected on the outer of gas cleaning plant
On housing.
The technical program is further arranged to：The warning part is buzzer, is fixedly connected on the outer of gas cleaning plant
On housing.
Through the above technical solutions, whether corresponding standby signal can be exported with warning lamp or buzzer, borrow
This reminds operator.
