BACKGROUND OF THE INVENTION The air pollution may generally be caused by the emis sion of, usually through thermal or incomplete combustion p rocesses, nitrogen, sulfur, oxygen, chlorine compounds etc.

, resulting from human activities in relation to the indust ry, traffic and the like, wherein sooty smoke, sulfurous ac id gas from petroleum-related industries and toxic gases such as carbon monoxide and nitrogen dioxide contained in t he exhaust gas from cars may constitute the main polluting source.

Hot smoke, fume, soot, odor and dust originating From

many plants, large buildings, power plants, trash burners , hospital waste incinerators, automobiles and the like a re seriously endangering the environment of the earth. Ne w meteorological phenomena like El nino and La nina have appeared to accelerate global glass-house effect leading to heavy rain, storm, heavy snow, severe cold and intense heat, depending on the regions, which were never seen bef ore. With the development of industrial society, the prod uction of waste gas has kept increasing, with the result that the air pollution has brought about the partial depl etion of the atmospheric ozone layer, a serious disaster, seemingly associated with various kinds of human diseases or disorders. Thus, many researches and developments have been made to respond to this urgent issue, so that a vari ety of relevant products and processes were made availabl e commercially.

The methods for treating harmful components in the atmosphere to remove them, in which facilities are provid ed right in apartment complexes or various plants generat ing waste gases to discharge the gases after treating the m, are mostly insufficient in that they mainly depend on filters simply to eliminate the filterable or catchable o bjects from the hazardous gases.

According to the other type of conventional waste g

as disposal methods, agents for treating hazardous compon ents or chemicals are employed, such that the chemicals r eact with the hazardous components to form precipitates, which are then collected for the purpose of burial or dis posal. This method is, however, associated with contamina tion of not only the rivers but also the soil, regardless of the perfectness of the method.

It is also known that the polluted air can be route d to pass through a accelerator bed for removing pollutan ts.

Therefore, the policy for protecting the atmosphere from pollution is intended to control the discharge of s ooty smoke generated in conjunction with business activit ies in plants and job sites, protect health and simultane ously conserve the life environment.

Conventional equipments and devices for removing po llutants in the atmosphere including various hazardous so oty smoke, dust etc. emitting from automobiles, manufactu ring plants, buildings and incinerators may function prop erly but still there is a need for additional kinds of su ch devices of simple design with good performance and at a low cost.

SUMMARY OF THE INVENTION

The object of the present invention is to help preven t the air pollution so as to protect the life environment b y providing a device for removing sooty smoke and the like emitting from manufacturing plants and business places.

The above object of the present invention is achieved according to an aspect of the present invention by a device for removing air pollution comprising an inflow pipe for in troducing the air or raw gas to the water in a tank, the pi pe having a suction opening equipped with a suction fan, an d a tank for containing the water, the tank having an injec tion opening for supplying water into the tank, a draining opening on the side of floor for draining the water from th e tank and a discharge opening for discharging the purified air or gas from the tank to the outside, wherein the end of the part of the inflow pipe immersed in the water is provid ed with an assembly of a filter with an apertures-formed lid and a baffle plate is formed at the location beneath th e discharging opening.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a sketch illustrating a device for rem oving the air pollution according to an embodiment of the i nvention, Figure 2 shows the exploded view of an assembly of a

filter and a lid on an inflow pipe and Figure 3 shows the cross section of an assembly of a filter and a lid at the end of an inflow pipe.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the invention will be described belo w by referring to the attached drawings.

In general, the present invention relates to air poll ution removing device comprising an inflow pipe 10 for intr oducing the air or raw gas to the water 30 in a tank 20, th e pipe having a suction opening 11 equipped with a suction fan 12 at one end of the pipe and having a lid 14 formed wi th apertures 15 and a filter 13 at the other end, the lid a nd filter being fitted together, and a tank 20 for containi ng the water, the tank having an injection opening 21 for s upplying water into the tank, a draining opening 22 on the side of floor for draining the water from the tank and a di scharge opening 23 for discharging the purified air or gas from the tank 20 to the outside, the discharge opening havi ng a baffle plate 24 located below.

The suction fan 12 located near the inlet in the infl ow pipe 10 is intended for forced feeding of the polluted a ir into the tank 20. On the bottom end of the inflow pipe 1 0, a filter 13 having ample void spaces for the purificatio

n of the polluted air is provided and a lid 14 is also prov ided to stop the air flow in the inflow pipe 10 and to hold the filter 13 in place and is formed with a number of apert ures 15 through which the air primarily cleaned with the he lp of the filter may pass into the treating water in the ta nk 20.

The size of the suction opening 11 should be adapted to that of the exhaust gas duct in which the inflow pipe 10 is installed, as the opening is hermetically connected to one of those ducts from cars, plants, buildings, incinerato rs and the like.

The provision of the suction fan 30 in the suction op ening 11 to increase the sucking gas volume into the tank 2 0 is optional, because, for example for application to a ca r, the fan is preferably not installed in order to avoid in fluencing the output of the car.

As the filter 13, any known filter may be used to pur ify the raw air preliminarily by removing dust or odorous p articulate in the air. The filter 13 may be disconnected fo r cleaning to increase its efficiency.

The lid 14 acts to prevent the filter 13 mounted in t he end of the inflow pipe 10 from falling off the pipe and accelerate the sucked air into the tank water through the h oles 15 formed in side wall of the lid 14. The end part of

the inflow pipe 10, filter 13 and lid 14 can be easily and hermetically assembled, as can be appreciated from Fig. 3.

The tank 20 made of the material like stainless steel , galvanized iron or plastic is provided with an injection opening 21 on its top for replenishing the tank 20 with wat er and with a draining opening 22 on its opposite bottom to drain the water. Additionally, the tank 20 is provided wit h an air discharging opening 23 having a baffle plate 24 ju st below the opening, that opening and baffle plate being 1 ocated on the top of the tank 20, so that the purified air free of water drops may be discharged to the outside after having been subjected to purification steps in the filter 1 3 and the water 30.

The water 30 filled in the tank 20 functions to remov e pollutant components contained in the raw air by contacti ng the air, as the air ascends through the water and theref ore should be maintained as liquid state all the time. Thus , antifreezing agent may be required to be added to the wat er in the winter. The amount of the water in the tank 20 sh ould be adjusted to optimize the absorbing capacity.

In operation, as already indicated in the above, the raw air contaminated with various smoke, fume, dust etc. is introduced by the fan 13 into the inflow pipe 10 through t he inlet 11, is freed of the dust or the like primarily wit

h the help of the filter 13, and subsequently passed throug h the apertures 15 into the water, where the air rises thro ugh the water, intimately contacting the water to be free o f remaining pollutants.
