Present coke oven configuration and runnability are: a coke oven is made up of 40～75 carbonization chambers usually, generally be that two coke ovens are formed a stove group, a stove group has a fixing operation sequencing, and each carbonization chamber is coaling successively according to this fixing operation sequencing and discharged of the coke operation in the stove group.Coke vehicle moves on coke oven, plays the carbonization chamber and the effect of docking conducting dedusting flue gas between the valve of coalingging or the discharging of the coke operation current.Because a common coke oven has 80～150 carbonization chambers, thus apart from the nearest carbonization chamber of dust pelletizing system blower fan and farthest the spacing of a carbonization chamber between 90～230 meters.Fixedly under the operating mode, 2 pressure difference can reach 600～1600Pa at blower fan.
With present coke oven dust blower fan control technique, when any one carbonization chamber is coaling or discharge of the coke operation, blower fan all is to work under the state of full speed running, can make the different carbonization chambers of same stove group remove the negative pressure value difference at dirt pits place, be the actual dedusting air quantity difference during different carbonization chamber dedusting in the same stove group, the actual dedusting air quantity of carbonization chamber is big more more nearby apart from the dust pelletizing system blower fan.Because the dust pelletizing system blower fan is to select apart from the design dedusting air quantity of blower fan farthest carbonization chamber according to satisfying, so the actual dedusting air quantity when present coke oven dust blower fan control technique makes other carbonization chamber dedustings has caused the waste of the energy all greater than the required air quantity of its dedusting.
Summary of the invention
The purpose of this utility model provides a kind of coke oven dust blower fan energy-saving control device, can be to the carbonization chamber of diverse location in the coke oven, adjust the rotating speed of control blower fan when high speed operation respectively, thereby when realizing to any coke furnace carbonization chamber dedusting, the actual air volume of dedusting all equals the required air quantity of dedusting, but the high speed operation rotating speed difference of blower fan reaches purpose of energy saving during to the coke furnace carbonization chamber dedusting of diverse location.
For achieving the above object, the utility model is achieved through the following technical solutions:
Coke oven dust blower fan energy-saving control device comprises pressure signal collecting device, coke oven dust PLC control system, fan speed regulation device, dedusting fan;
Described pressure signal collecting device is arranged on the pressure value in the conducting pipeline when being used for the continuous acquisition dedusting in the dedusting conducting pipeline of coke vehicle, and the pressure value of gathering is sent to coke oven dust PLC control system;
Described coke oven dust PLC control system receives the interior pressure value signal of dedusting conducting pipeline that the pressure signal collecting device is gathered, and with the pressure value that receives with set numerical value and compare computing, produce control signal according to operation result then, and the fan arrangements for speed regulation that transmit control signal;
Described fan speed regulation device is connected with dedusting fan, is used for controlling the rotating speed of dedusting fan.
Compared with prior art, the beneficial effects of the utility model are:
By the utility model can corresponding coke oven in the coke furnace carbonization chamber of diverse location adjust the rotating speed of blower fan when the high speed operation respectively, thereby when realizing to any one coke furnace carbonization chamber dedusting, the actual air volume of dedusting all equals the required air quantity of dedusting, but the high speed operation rotating speed difference of blower fan during to the coke furnace carbonization chamber dedusting of diverse location.Promptly satisfy the dedusting requirement of each coke furnace carbonization chamber by the technical program, reached the purpose of control blower fan energy-saving run again.
In the whole world all in the today of advocating environmental protection, energy-saving and emission-reduction, China is also improving year by year to the requirement of highly energy-consuming industry energy-savings such as iron and steel industry, coking consumption reduction, the energy-conserving control technology of coke oven dust blower fan helps coal chemical enterprise and reduces energy consumption and cost of production, has remarkable economic efficiency and social benefit; Help the energy-saving and emission-reduction work of coking production enterprise, the market competitiveness of raising enterprise.
