Abstract

A process for removing soot from gases produced during the combustion of solid, gaseous or liquid fuel by means of a plurality of contact treatments i.e. spraying water onto the soot gas containing and exerting centrifugal force on the soot water mixture so as to cool, condense and precipitate the suspension particles including ash and impurities in the soot which will flow out together with the water.

Description

SPECIFICATION A process of treatment for soot purification This invention is related to a process of treatment for soot purification which can minimize the soot produced during the combustion of fuel.

Machine has replaced handicraft and the people acquired the required power to actuate the industrial production by various different means since the industrial revolution. This power includes steam, electricity, gas and oil pressure. The source of this power relies on various different impetus machines through the combustion of solid, liquid and gaseous fuel. In the course of fuel combustion, the high temperature leads to physical and chemical changes which produce the chemical gas and the soot with floating particles to go with the wind in the atmosphere in line with principle of hot air rising upward, and the dirty ingredient thereof such as CC, OO and ash in quantities easily tend to cause air pollution.

Along with the high-degree in economic growth, the product of combustion accelerates the environmental pollution which not only deteriorates the people's living space and surroundings but also unfavorably affects the life and health of mankind.

Therefore, the appeal to environmental protection and countermeasure concerned becomes a focus of emphasis in the present industrial world wherein a simple and easy process for effectively solving the problem of soot polution is further pursued.

An object of this invention is to offer a process of treatment for soot purification wherein the temperature of suspension particles and impurity in the soot is dropped when they pass this invention and mix the atomized water to condense and precipitate with the water and exhaust with the hot air so as to achieve the purpose of purification.

Another object of this invention is to offer a process of treatment for soot purification wherein water is atomized to stir and mix the soot through the rotation of water and rotary shaft so as to achieve the purpose of purification.

Still another object of this invention is to offer a process of treatment for soot purification with a simple construction, cheap cost, high-degree purification treatment efficiency and outstanding performance but without any malfunction.

Further another object of this invention: It may be a single combination in keeping with a motor and a separate water-pumping pump as wil as a water tank so that the air intake pipe may be connected to the exhaust hole of car in order to lower the soot produced by the car.

According to the present invention there is provided a process of soot purification comprising passing soot from a furnace into a at least one hermetically sealed container in which the soot is diffused by a rotatable flow distributor located within the container, spraying water onto the soot from a plurality of nozzle grooves on the exterior of the container such that centrifugally atomized water produced by the sprayed water impacting upon the flow distributor mixes with the soot to condense and precipitate the soot, and removing floating particles in the soot with the water drained from the container.

An embodiment of the present invention will now be described by way of example, with reference to the accompanying drawings, in which Figure 1 is a perspective view of an embodiment apparatus used in 25 accordance with this invention.

Figure 2 is a side view of the embodiment shown in Figure 1, Figure 3 is a sectional view of part of the embodiment shown in Figure 1, Figure 4 is a side elevational view of a rotary shaft used in the 30 apparatus of Figure 1, Figure 5 is an end view of the rotary shaft of Figure 4, The process of treatment for soot purification of this invention wherein when the soot produced during combustion enters this invention through a smoke pipe, the power from a motor drives the soot in this invention to diffuse and to stir and mix with the atomized water through another impetus source so that the atomized water forces the soot temperature to drop and condenses and precipitates the floating particles in the soot to be exhausted together with the water flow.The connection in series with a unit of this invention can achieve the purpose of soot purification through the foregoing plurality of condensation and precipitation.

As shown in the drawings, the process of treatment for soot purification comprises a round hermetic container 4, a rotary shaft 14, a transmission mechanism 10, a motor 9, a flow distributor 15, some nozzle grooves 5, an inflow pipe 11, an outflow pipe 8, etc.

As shown in Figure 1, the soot produced in furnace 1 may be exhausted directly from a chimney 20 and enter the round hermetic container 4 through the smoke pipe 3 after cutover by an electrically controlled butterfly valve 2 (not shown in Figure 1). The round hermetic container 4 is mounted on the frame 12, an inlet and an outlet of smoke pipe are at the two eccentric ends of side cover, the smoke pipes 3, connected to the furnace 1 or the second treatment container is designed to exhaust the soot. A bearing thereon supports the rotary shaft 14, a flow distributor 15 is mounted axially, the air holes 16 which are arranged equidistantly on the flow distributor 15 can disperse the soot in the smoke pipe into the round hermetic container 4. A rotary shaft 14 with a belt wheel 10 fixed at one end thereof is driven by the motor 9 so as to make the bearing to rotate.The round column of rotary shaft 14 is filled with the equidistantly arranged round needle-shaped projections 17 (as shown in Figure 5). A plurality of nozzle grooves 5 on the exterior of round hermetic container 4 are connected to the water source 7. The nozzle of nozzle grooves spray the water centripetally toward the direction of rotary shaft 14. The water source 7 is pumped by a pump into the nozzle grooves 5 for spraying through the two sides of said container 4. When spraying the water, the round needle-shaped projections 17 on the column of rotary shaft 14 driven by the power to rotate have to make the water columns atomize and to stir and mix with the diffused soot on the flow distributor 15.The soot temperature is dropped since the atomized water mixes with the hot soot wherein the suspension particles and impuritycondense with the atomized water and precipitate at the bottom of round hermetic container 4 where a drain connected to a drain pipe 8 which drains the water with precipitation comprising the ash and suspension particles into the water tank. Meantime, a part of hot soot in the round hermetic container 4 is condensed by the atomized water and another part there flows into another round hermetic container 4 through the smoke pipe 3 on account of the hot air rising upward to get through another process of treatment.In view of the above, more than one round hermetic container 4 may be connected in series and to the pipeline and power concerned, depending on the ingredients of fuel, so that the soot is subject to a plurality of same process of treatment and the floating particles in the soot is minimized due to condensation and exhausted into the atmosphere so as to minimize the air polution.

This invention has the value for industrial use since the above structure can minimize the extent of soot pollution through the process of treatment of this invention so far as the soot exhausted from the furnace is concerned.
