Background technology
Dry coke quenching IDC is an advanced technology that reclaims coking waste heat, be called for short CDQ, dry coke quenching IDC utilizes gravitational dust collection principle that the bulky grain coke powder in recyclegas is separated, after the dedusting of gravitational dust collection chamber, enter boiler, coke powder enters ash silo, the control of dry coke quenching ash silo material level is extremely important, washes away generator tube if the too high coke powder of material level can enter boiler with air-flow, causes boiler booster; If material level is too low, can burn out water cold sleeve.The ash silo charge level control device using at present, comprise dry coke quenching ash silo, high abrasion water cold sleeve, rotation unloading valve and static capacity level-sensing device, water cold sleeve is located at the bottom of ash silo, be provided with rotation unloading valve in the lower end of water cold sleeve, static capacity level-sensing device is located on the sidewall of ash silo, measure the upper limit material level in ash silo by static capacity level-sensing device, in the time that upper limit material level is reported to the police, start the rotation unloading valve coke discharging powder under water cold sleeve, control and unload ash interval time and unload the ash time.The deficiency of this dry coke quenching ash silo charge level control device is: due to the poor accuracy of static capacity level-sensing device, so often there is wrong report, cause the too high or emptying of 1DC ash silo material level, boiler and water cold sleeve are caused damage, impact is operation normally; Meanwhile, because static capacity level-sensing device is import, so investment is large.In order to change above the deficiencies in the prior art, known by retrieving, some employings Temperature Distribution principle in dry coke quenching ash silo detect material level, can replace static capacity level-sensing device, change but there is not yet by the pressure in dry coke quenching ash silo the report that carrys out prosecution material level.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, accuracy is high, cost is low, changes by the pressure detecting in dry coke quenching ash silo the automatic measuring and controlling device of dry coke quenching ash silo material level that carrys out prosecution material level.
In order to reach above object, the technical scheme that the utility model adopts is: the automatic measuring and controlling device of this dry coke quenching ash silo material level, comprise dry coke quenching ash silo, high abrasion water cold sleeve and rotation unloading valve, high abrasion water cold sleeve is established two, all be fixed on the bottom of dry coke quenching ash silo, and be connected with dry coke quenching ash silo, be equipped with rotation unloading valve in the lower end of two high abrasion water cold sleeves, it is characterized in that: the sidewall middle part of described dry coke quenching ash silo one side is provided with connection side pipe, be provided with ring flange in the end that is communicated with side pipe, and connect nipple by ring flange, end at nipple is provided with ball valve, a side at nipple is provided with force pipe, end at force pipe is provided with pressure vacuum gauge, be provided with pressure inverting pipe at the opposite side of nipple, at the end of pressure inverting pipe Bonding pressure transmitter, pressure unit is connected to the PLC switch board in master-control room by transmission cable.
The utility model is also implemented by following measure: the interior diameter of described nipple is 80mm, and length is 300mm; The axis of nipple is perpendicular to the sidewall of dry coke quenching ash silo.
The beneficial effects of the utility model are: this dry coke quenching ash silo material level automatic detection device, simple in structure, accuracy is high, cost is low, can not only automatically detect, can also check that tensimeter carries out on-site manual and unloads ash by scene, can avoid wrong report, prosecution dry coke quenching ash silo material level, guarantees equipment security of operation effectively.
