Technical field
The present invention relates to a kind of glance coal cleaning system discharge quantity metering device and control method, more particularly to a kind of application
The accurate metering device and control method of powdered carbon discharge quantity in the Green anode making asphalt smoke purifying system of multiple spot blanking technology.
Background technology
The major way of preceding bitumen flue gas Treatment process is to install a flue gas after first flue gas is collected on supervisor is collected
Reactor, reactor and bitumen flue gas mixing and absorption are transported to by material conveying device under powdered carbon by powdered carbon, then are removed by cloth bag
Powdered carbon after absorption is separated return technological process from flue gas and is continuing with by dirt device.Due to only installing reactor on supervisor,
Therefore a set of powdered carbon blanking measurement device only need to be configured, powdered carbon discharge quantity metering device commonly uses the mode of spiral title, charcoal filler bin
The mode receiver bin of controlling level in storehouse, radar level gauge or level switch measurement is measured by radar level gauge or level switch
Interior dust interference, precision and stability are poor.
With the extensive use of multiple spot blanking bitumen flue gas Treatment process, multiple spot blanking technology follows the spy from watershed management
Point, installs smoke reaction device on the gas-collecting branch pipe in the source that bitumen flue gas produces, powdered carbon is passed through material conveying device under powdered carbon
It is delivered to each branch pipe smoke reaction device.The green anode asphalt smoke purifying system of generally use multiple spot blanking technology need to configure 3 ~
5 sets of powdered carbon blanking measurements and conveying device, while require the discharge quantity for often covering powdered carbon blanking measurement device accurately to measure simultaneously energy
It is adjusted as needed.The spiral title powdered carbon blanking measurement device of more sets is configured according to conventional method, system cost can be caused
Increase, device complexity, high failure rate, inconvenience are safeguarded, need periodic calibrating each spiral the problems such as claiming, taking up a large area, especially
Charcoal filler bin lower part installation space is small can not to provide more spiral title fabricating yards of set.
The content of the invention
The technical problem to be solved in the present invention is:Study a kind of glance coal cleaning system discharge quantity metering device and controlling party
Method, the spiral title powdered carbon blanking measurement device of more sets that substitution needs originally, more spiral titles of set are needed to configure to solve the prior art
Powdered carbon blanking measurement device, cause system cost to increase, device complexity, high failure rate, inconvenience safeguard, need each spiral shell of periodic calibrating
The problem of rotation claims and installation takes up a large area.
