Abstract

PURPOSE:To obtain an efficient exhaust gas purifying device by a simple structure wherein an inner liner, at the lower part of which communicating holes are provided, is installed in an outer liner and the gap between both the liners is blocked and then a capillary tubing is provided so as to connect the lower part of the outer liner with the upper part of the inner liner. CONSTITUTION:Due to the exhaust gas forwarded in a first agitating chamber 4, a rotating shaft 9 is rotated by means of a fan 10 and at the same time the washing water in an inner liner 2 is pushed, resulting in spraying the washing water through a capillary turbing 14 into the first agitating chamber 4. Thus, the mixing of the exhaust gas with the washing water and the lowering of the exhaust gas temperature are resulted. Next, the mixed gas enters a second agitating chamber 5, in which the exhaust gas is brought into contact with the washing water by means of blades 11, past through communicating holes 12, then led to a third agitating chamber 6, and finally discharged outside through an exhaust pipe 15.

Description

[Detailed Description of the Invention] This inner side 15. (My friend's Ji Gas Purification PF)
Regarding.

i,',suJj:・j (including harmful substances such as co, co2, and NQx from the exhaust gas of 1)
Purifiers for removing dust were devised in the eastern part of Japan, and they were difficult to dig and were expensive.

The object of this invention is to provide a purification device which is simple in construction, inexpensive, and has a high purification efficiency.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing embodiments thereof.

): As shown in Figures 1 to 4, an inner cylinder 2 is provided coaxially within an outer cylinder 1 whose upper and lower surfaces are closed, and a rain gap 1.2 is provided.
Washing water is provided inside. The upper part of the 1111 cover of both cylinders 1.2 is closed by a conical partition plate, and the first pipe...
A stirring chamber 4, a second stirring chamber 5, and third and third stirring chambers 6 are formed. At the top of the outer cylinder 1 there are four pipes for the exhaust gas from the internal combustion engine.
is connected, and exhaust gas is sent from this pipe 7 to the "611%! stirring pipe 4.".

The inner cylinder 2 is supported by a bearing 8 on the center 1j41. 3 is provided, and this l1III9
A screw type fan 10 is installed in the upper world 5. When gas is fed into the exhaust 1 into the eleventh furnace stirring chamber 4, the shaft 9 is rotated by the fan 10. A stirrer (11) is provided in the washing water under the rotary shaft (9), and this stirrer (11) causes the gas sent from the first stirring chamber (4) to mix with the washing water (7).
The mixture is stirred.

A communication hole 12 is formed at the lower end of the inside of which is 1102.
The 431 gas in the first chamber 5 leaks through this communication hole 12 and enters the fourth stirring chamber 6. A through hole 18 is formed in the required height of the inward direction 2 in the circumferential direction with an appropriate distance between the outgoing holes 18,
Third stirring chamber 6 pushed up by the pressing force of some particles
The cleaning water inside is coming from this hole 13? β2 falls into the stirring chamber 5 and is generated in the second stirring chamber E when the water surface of the chamber 6 is evenly distributed. 71-'i of the package will be removed.

Due to the % phenomenon and the action of the ejector, purified water (11) is lifted up from this thin tube (14) and sprayed into the stirring chamber (1). The number of gWil 'i'i' i -4 may be determined as appropriate, or it is preferable to provide them 1jfl' in the cylindrical direction of the outer cylinder 1, etc., as shown in No. 31 S'l.

Next, the operation of this device A will be explained.

Now, number 1. Exhaust gas is sent into the HI stirring push chamber, and the rotation shaft 9 is rotated by the fan 10, and when the 3'=purified water in the inner cylinder 2 is pushed, the water changes from fine % 14 to lth

The grass 3 is brought into contact with L purified water, passes through the communication hole 12, enters the stirring chamber 6, and is discharged from the knob 1 through the trachea 15 to the outside. In the washing water, the gas is stirred by the inflow of gas, and the gas-liquid chamber is smoothly removed, and harmful substances such as CO and dust are removed. It will be done.

As shown in FIG. 2, cooling is preferably performed by circulating wash water through the cold JPv device 16. This circulation is also carried out by the same action as the thin tube 14, so that the temperature is lowered by misting the hand water into the first room, which is cooled at 4°, in one line. It is recommended that you do this.

It is preferable that the cooling water to the cooling k<16 is supplied from a closed replenishment tank 17, and from this tank 17 it is possible to supply cleaning water to the apparatus A at the same level. Is it possible to circulate cold water by a pump or by using cooler 16 and tank 1?
This is also done by the temperature difference between 7 and 7. In the figure, 18
is a heat exchanger coil.

Since the washing, fighting, Jf4 mixing of R and 81 gas is carried out by using the 81 gas, the fan 10 is not necessary, but it is not necessary to install it.Also, the through hole 13 is also It is not necessary to provide g for low ones.

As shown in Iλl, 5 Hgl, a downward radial arm 19 is provided on the shaft 9, and this uppermost arm 19 disturbs the flow of exhaust gas! At the same time, remove the upper part of the bubbles generated on the top surface of the λ purified water. , +h. Arm 19 in the wash water is also the same male;
Perform the stirring action on it. The axis V may be a 1 ml fixed axis, but if it is a rotating axis, the arm 19 will rotate, and its stirring effect will be improved.
