This multiple-effect automobile exhaust gas purifying installation is characterized in that: described gas-liquid separation settling tank is provided with hand hole, and screen cloth can be through these disassembly, cleaning.
This multiple-effect automobile exhaust gas purifying installation is characterized in that: in the liquid handling pipe, activated carbon adsorption layer is fixed in pipe by screen, detachably changes acticarbon.
The present invention compared with prior art has the following advantages:
This apparatus structure is simple, is convenient to install, practical.
This device adopts water as processing raw material, with low cost, be easy to realize, and treatment effect is good.
This device adopts and divides gas and two kinds of approach of liquid further to process to the harmful gas after water atomization, pollutant to gaseous state is innoxious by ternary catalyzing unit, pollutant to liquid condition is removed by filtering and adsorbing effectively, has significantly improved treatment effect.
This device is provided with three place's screen clothes, and not only protective gear is not blocked, and has tackled to the utmost fine particle and enter atmosphere.
This device controls to the water yield and spraying size the waste of avoiding causing resource and the energy according to air displacement by inductor.
This device liquid handling passes into water tank after purifying with the multilayer active carbon adsorption after filtration, realizes recycling, and has not only saved water resources, and has facilitated use, has strengthened practicability.
In sum, this device can reduce the deleterious particle material in tail gas to greatest extent, harmful gas is converted into to innocuous gas and enters air, realizes recycling of water resources simultaneously, really reaches the purpose of " energy-saving and emission-reduction ".
Four, accompanying drawing explanation
Fig. 1 is that multiple-effect automobile exhaust gas purifying installation structural representation is (in figure: 1: vehicle-exhaust exhaust pipe; 1-1: pressure inductor; 2: the spraying purifying box; 3: booster pump; 4: intake pipe; 5: water tank; 5-1: water meter; 5-2: filler; 6: waste pipe; 7: miniature elevator pump; 8: the gas treatment pipe; 9: ternary catalyzing unit; 10: the Purge gas outlet pipe; 11: the liquid handling pipe; 12: activated carbon adsorption layer; 13: sewage draining exit; 14: the gas-liquid separation settling tank; 14-1: hand hole; 14-2: screen cloth; 14-3: inclination screen cloth; 14-4: screen cloth; 14-5: hand hole; 15: the water atomization shower nozzle)
Five, embodiment:
During car engine, booster pump (3) is started working, the inner water of water tank (5) passes into water atomization pressure nozzle (15) by intake pipe (4) and starts water spray, the tail gas that automobile is discharged directly enters spraying purifying box (2) from outlet pipe (1), the atomized water of shower nozzle ejection and CO, the CO2 in tail gas, HC, NOX, lead compound, oxygen sulfur compound, imperfect combustion carbon microsphere etc. mix, collide with each other, adsorb, fine particle swells because absorbing moisture, and the existence of water smoke also can make particulate mutually adsorb and get together and form more macroparticle.Then enter gas-liquid separation settling tank (14), the particulate matter sedimentation swollen due to Action of Gravity Field, wherein larger particle filters in the gas-liquid separation settling tank through screen cloth (14-3), the less screen cloth that passes through.Liquid by screen cloth (14-4) enters liquid handling pipe (11), and pollutant is removed substantially through multistage activated carbon adsorption layer (12) suction-operated, and the water after purification is transported in water tank and recycles through miniature elevator pump (7); The ternary catalyzing unit (9) that also has part to connect through gas treatment pipe (8) without the gas of sedimentation effectively is converted into free of contamination gas and drains into atmosphere from relief opening (10).
Automobile start, travel and the process such as acceleration in air displacement be different, for saving water resource, this device is provided with pressure inductor (1-1) in vehicle-exhaust exhaust pipe, inductor can transmit air displacement information to micro pressure pump (3), add big water quantity when air displacement is large, air displacement hour, reduce the water yield, control inflow with this, saving water resource.
Waste gas mixture after water mist sprinkling enters gas-liquid separation settling tank (14), for avoiding the part particle enter atmosphere or stop up the liquid handling mouth of pipe, therefore three place's screen clothes are set: the tilted screen cloth of gas-liquid separation settling tank (14-3), gas treatment tube inlet place screen cloth (14-2), liquid handling ingress screen cloth (14-4).Described first place's screen cloth is obliquely installed the surface of contact not only increased with pollutant, and make a part of pollutant and moisture from, tackled better particulate pollutant.Described second place's screen cloth can avoid part not Deposited particulate matter enter in pipe and enter atmosphere.Described front two place's screen clothes are provided with hand hole nearby, so that screen cloth can disassembly, cleaning.Described the 3rd place's screen cloth can prevent the Particle Blocking liquid handling pipe of part without interception, further tackles particulate matter, and the particulate matter of tackling can be discharged through sewage draining exit (13) nearby, recycling.
In described liquid handling pipe, activated carbon adsorption layer is fixed in pipe by screen, detachably changes acticarbon.
