The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of rubbish landfill gas pretreatment unit, comprise pretreatment pipeline 1, be connected with separator 2 in the exit of pretreatment pipeline 1, be connected with water pipe and tracheae on described separator 2, be connected with roughing efficiency air filter 3, aqueous vapor heat exchanger 4, liquid-gas separator 5, roots blower 6, coalescent filter 7 and output channel 8 in the exit of tracheae in turn; The outlet of described output channel 8 is connected with generating set 9; Be connected with respectively malleation water pot 10 and negative pressure water pot 11 on water pipe, be equipped with on described malleation water pot 10 and control the ball-cock assembly 12 that water drains into condensation ditch 20; Be connected with fluid level controller 13 and water pump 14 on described negative pressure water pot 11 in turn.Be provided with pressure transmitter 15 on described output channel 8, described pressure transmitter 15 is connected with roots blower 6 signals.On described output channel 8, humiture transducer 16 is installed; Can the finished product gas that be delivered to generating set 9 be detected like this.
Described roots blower 6 is frequency conversion roots blower 6.Be provided with the explosion-proof temperature sensor on the bearing of described roots blower 6.Above-mentioned pressure transmitter 15 output pressure signals are to roots blower 6; roots blower 6 carries out variable frequency adjustment after receiving pressure signal; for avoiding the fan outlet hypertonia, be provided with the backflow of two-way pneumatic bypass on the air inlet of roots blower 6 and the house steward that gives vent to anger blower fan is protected.Bearing temperature adopts explosion-proof temperature sensor PT100 to make temperature element, and every roots blower 6 has two temperature sensors.Totally 4 temperature points, the bearing temperature of roots blower 6,90 ℃ of alarming values, 95 ℃ of shutdown values.
Be equipped with manually-operated gate 19 on described pretreatment pipeline 1 and output channel 8.Be provided with emergency pneumatic stop valve 17 and spark arrester 18 on described output channel 8.
Above-mentioned aqueous vapor heat exchanger 4 is connected with handpiece Water Chilling Units, and the start and stop of handpiece Water Chilling Units are controlled according to water outlet and the return water temperature of handpiece Water Chilling Units.
Operation principle of the present utility model is: refuse landfill comes gas to enter 2 minutes water of separator by pretreatment pipeline 1, the draining of separator 2 is divided into positive pressuring drainage section and drainage by suction section, the draining of drainage by suction section is connected to negative pressure water pot 11, then the start and stop of controlling water pump 14 by fluid level controller 13 drain into condensation ditch 20.The positive pressuring drainage section is directly by ball-cock assembly 12 drainings, to condensation ditch 20; The rubbish landfill gas separated through separator 2 enters roughing efficiency air filter 3, remove the particle in rubbish landfill gas, through aqueous vapor heat exchanger 4 cooling 15 degree, produce a large amount of condensed waters and discharge from aqueous vapor heat exchanger 4 bottoms again, fine drop is with air-flow rotating separation dehydration in liquid-gas separator 5.Rubbish landfill gas after liquid-gas separator 5 dehydration is boosted after roots blower 6 compressions output.Rubbish landfill gas after supercharging, by coalescent filter 7, guarantees the granularity of air feed; Rubbish landfill gas through coalescent filter 7 is delivered to generating set 9 after the humiture conveyer detects.
