Further, said intake-discharge pipe stretches under the buck bucket liquid level, and the discharge outlet of intake-discharge pipe communicates with absorbing the storehouse, and the water inlet of intake-discharge pipe connects the buck source.
Further, the said subsurface upper hose of the aqueous slkali bottom of stretching into is provided with filter.
Further, said inlet duct comprises heater, and inlet channel is arranged on the heater, connects scalable flexible pipe at the airintake direction upper heater, and scalable hose is provided with air inlet.
Further, said aqueous slkali is a sodium hydroxide solution.
Further, said absorption storehouse outer wall has heat-insulation layer.
Further; Said street lamp also comprises running water high-pressure spraying system, and running water high-pressure spraying system comprises running water pipe, high-pressure pump, water inlet pipe and high-pressure nozzle; Running water pipe stretches into below ground; Running water pipe connects high-pressure pump, and the high-pressure pump water side connects water inlet pipe, and the water inlet pipe end connects the downward shower nozzle of injection direction.
Further, on the street lamp lamp bracket that said water inlet pipe is fixed.
This street lamp that purifies air that the utility model relates to, its basic functional principle is following: sulfur dioxide, nitrogen dioxide, carbon dioxide are water-soluble, and NaOH (5% ~ 40%) neutralization generates salt; Utilize the freely falling body principle of weight, the globule is fallen by height downward vertically, and dust and water merge mostly.

Fig. 1 is the utility model street lamp overall structure sketch map that purifies air.
Mark is represented as follows among the figure: the 1-street lamp; 2-seals; The 3-gas outlet; The 4-suck pump that makes progress; The 5-shower nozzle; 6-absorbs the storehouse; The 7-upper hose; The 8-outer wall; The scalable flexible pipe of 9-; The 10-air inlet; 11-advances discharge outlet; 12-ground; The 13-intake-discharge pipe; 14-buck bucket; The 15-sodium hydroxide solution; 16-filters mouth; The 17-high-pressure pump; The 18-high-pressure pump; The 19-running water pipe; The 20-heater; The 21-water inlet pipe; The 22-shower nozzle.
The specific embodiment
As shown in Figure 1, street lamp comprises the aqueous slkali clear air system; The aqueous alkali clear air system comprises buried buck bucket 14, intake-discharge pipe 13, high-pressure pump 17, absorbs storehouse 6, upper hose 7, suck pump 4 upwards; Upper hose 7 stretches into below the buck bucket liquid level of solution; Upper hose 7 bottoms connect high-pressure pump 17, and the top connects the downward shower nozzle 5 of injection direction; Buried buck bucket 14 is at below ground, and upper hose 7 is arranged on and absorbs in the storehouse 6, and the upper hose bottom is provided with filter, and absorbing storehouse 6 is the barrel-shaped storehouse of a sealing, and the top connects upwards suck pump 4, and the middle part is provided with inlet duct; Inlet duct comprises heater, and inlet channel is arranged on the heater, connects scalable flexible pipe at the airintake direction upper heater, and scalable hose is provided with air inlet.Aqueous slkali can be sodium hydroxide solution.The top that absorbs storehouse 6 promptly upwards the top of suck pump 4 be provided with the gas outlet.
Intake-discharge pipe 13 stretches under buck bucket 14 liquid levels, and the discharge outlet of intake-discharge pipe 13 communicates with absorbing storehouse 6, and the water inlet of intake-discharge pipe 13 connects the buck source.
When the suck pump work that makes progress, the high-pressure pump of sodium hydroxide solution is worked simultaneously, and the former is sucked the air that pollutes and absorbs in the storehouse by air intake duct, by moving upward under the pipe, up to top exit, purified gas is discharged; The latter from bottom to top delivers to water jet place with sodium hydroxide solution through piping by high-pressure pump, and solution is sprayed downwards, and the globule of solution is under the gravity effect and under the external force effect; Move downward rapidly; Contact fully, mix with sulfur dioxide, nitrogen dioxide, carbon dioxide in the dusty gas that moves upward, neutralization generates salt, or water-soluble; Make vaporous pollutant, become aqueous salting liquid.
Absorb storehouse outer wall 8 and have heat-insulation layer.Work owing to the heating equipment in winter has increased the weight of air pollution, so this equipment, must work winter; For safety, in order to save cost, so with the buck bucket of NaOH, buried underground; To be exposed at all outdoor key equipments simultaneously and be incubated processing, as required, the place has installed electric heating equipment additional at air inlet; The air that makes severe winter gets into absorption chamber after heating, guarantee the operate as normal of the aqueous solution of absorption chamber.
Street lamp also comprises running water high-pressure spraying system; Running water high-pressure spraying system comprises running water pipe 19, high-pressure pump 18; Water inlet pipe 21 and high-pressure nozzle 22, running water pipe 19 stretches into below ground, and running water pipe 19 connects high-pressure pump 18; High-pressure pump 18 water sides connect water inlet pipe 21, and water inlet pipe 21 ends connect the downward shower nozzle 22 of injection direction.
Running water high-pressure spraying system is sent to the top spout place of lamp by low to height with running water by high-pressure pump, and water is sprayed.Act on: move when wagon flow and bring a lot of dust in air, according to actual needs, the street lamp that the whole street is had this function is all opened, and makes water side's ejection in the street simultaneously; Make to be suspended in airborne dust and water melts, along with the globule falls into the face of land, airborne dust is just few naturally, drops on the globule on the face of land; Can also make the road surface keep temporary transient humidity, and not make dust once more automobilism arranged and bring in the air, this is in the long-term drying of air ratio of not raining with; Dust is bigger, under the many situation of road surface car, haves no alternative but temporary transient emergent means; Can not use winter, and its advantage is in time, effectively, can separate for the moment being stranded.
During use, add sodium hydroxide solution from advancing discharge outlet, solution height can not be higher than 3/4 of buck bucket; Be in order to guarantee that aqueous slkali can not overflow under special external force effect, to guarantee safety like this; To lock advancing port flap after adding solution; Prevent that the layman from operating without authorization, rainwater flows into the buck bucket when preventing to rain, and solution is overflowed.Regularly from advancing discharge outlet, discharge the product and the deposition of neutralization with professional transport vehicle and evacuation system.
The result is that the carbon dioxide process mixes, neutralizing reaches about 30%, and sulfur dioxide, nitrogen dioxide reach 60%, makes final gas obtain the purification of part, enters atmosphere.This is operated in and pollutes heavy city, should continuous operation in 24 hours, and it is equivalent to the effects of 500 same time absorbing carbon dioxides of tree.
This street lamp that purifies air that the utility model provides, two autonomous systems rely on the platform of street lamp, play different effects, and are to the effect that present municipal pollution can play alleviation, alleviate, especially the most obvious to the carbon dioxide effect.
The described specific embodiment of the utility model does not constitute the restriction to the application's scope; Within every spirit in the utility model design and the principle, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the utility model.
