In the present embodiment, a described pressure charging system comprises the pressure transmitter, manual shut-off valve, the manual shut-off valve of bypass, the Pressure gauge that before and after booster fan and blower fan that two covers are set up in parallel, pipeline are arranged; Described secondary booster system also comprises the pressure transmitter, manual shut-off valve, the manual shut-off valve of bypass, the Pressure gauge that before and after booster fan and blower fan that two covers are set up in parallel, pipeline are arranged.Described biogas delivery pipeline system comprises the manual shut-off valve in front and back, bypass shut-off valve, Pressure gauge, gas filter, combustion gas blowoff valve, pressure transmitter, the low alarm switch of pressure, the low excision switch of pressure and the three valve groups that two covers are set up in parallel, and often overlaps biogas delivery pipeline system and is communicated with a set of described boiler-burner respectively.Described boiler-burner is communicated with blowing system, the pipeline of blowing system is provided with electric adjustable air doors, pressure switch and Pressure gauge.
The utility model is applicable to biogas comprehensive utilization 35 tons of CFBBs, and the biogas that sewage disposal produces after 500 side's gas holders store, then rises through frequency conversion the burner that boiler internal sent into by blower fan, reaches the effect of saving thermal coal.
For ensureing biogas combustion, gas holder carrys out atmospheric pressure and is not less than 500Pa, Tathagata atmospheric pressure is higher than 5KPa, directly can enter gas holder, dish gas holder is filled with as can be carried out the boosting of Roots's booster fan at 500-5000Pa, biogas from dish gas holder out after through water sealed tank and gas-liquid separator, then after the supercharging of freq uency conversion supercharging blower fan about 20kPa, after enter boiler-burner and burn.Native system arranges two cover booster fans (the using and the reserved).Biogas also has two combustion fans to carry out the oxygen needed when blowing to provide burning when entering boiler combustion.User needs to consider the fixing of Roots's booster fan and rainproof measure, and Roots's booster fan on-site control is placed near blower fan.
Pressure charging system comprises the pressure transmitter before and after blower fan, manual shut-off valve, the manual shut-off valve of bypass, Pressure gauge etc.
Two burners established by boiler, and burner nozzle front end adopts heat resisting steel to make, to guarantee the service life of nozzle.Burner fuel is biogas, as mixing fuel burning, can not use separately, only as normal combustion use, does not use as igniting when starting.When reaching in burner hearth more than biogas ignition temperature (about 650 DEG C), just biogas can be sent into, ensureing that biogas burns completely, avoiding biogas enter imperfect combustion in burner hearth and gather, thus cause the consequence of blast.
Burner is equipped with a set of flame detector, be mainly used in monitoring flame conditions, steady fiery structure is provided with in burner, ensure all can not stop working under various operating mode simultaneously, safe and reliable, in order to flame detection state, when burner normal combustion, fire inspection processor sends switching value and analog signals, and when burner accident extinguishing, " without fire " signal will be transferred into DCS system.Flame detector need be equipped with cooling air, to guarantee that flame detector can be cooled reliably when burner runs and stop transport.
