Abstract
The invention relates to a diesel engine waste gas purification box, wherein a box cover and a box body are connected in a sealing way through a seal gasket and a fastening piece, and an exhaust pipe is tightly fixed on the box cover; a water outlet with a screw plug is arranged at the bottom of one lateral surface of the box body; a water inlet with a screw plug is arranged above the water outlet; clear lime water is filled between the water inlet and the water outlet in the box body; a Z-shaped gas inlet pipe consists of an upper horizontal pipe, a vertical pipe and a lower horizontal pipe which are communicated into a whole, wherein the cylindrical surface of the lower horizontal pipe is provided with a vent hole, the lower horizontal pipe is horizontally arranged in the lime water at the bottom of the box body, and the upper horizontal pipe below the box cover extends out of one lateral surface of the box body; a water-stop sheet provided with a vent hole is horizontally arranged between the upper horizontal pipe below the box cover and the upper edge of the water inlet in the box body; and a port of the exhaust pipe in the box body is positioned above the water-stop plate. Waste gas discharged from a diesel engine is neutralized and filtered by the lime water, and the waste gas and carbon fume particles are dissolved or precipitated in water, therefore noise is greatly weakened. The diesel engine waste gas purification box has the advantages of simple structure and low cost; and the cost of replacing the lime water periodically is also low.
Description
Technical field
The present invention relates to a kind of tail gas purification device of combustion engine, particularly a kind of diesel exhaust purifying box.
Background technique
[0002]Some is to use diesel-engine road vehicle to carry out hauling operation in middle-size and small-size underground mine and the rural area; And the oil smoke severe contamination surrounding environment that diesel engine is discharged; Adopt the netted noise reduction purifier of common metal effect bad; Existing many baroque noise reduction purifiers and platinum, palladium ceramic reduction catalyzer cost height, inapplicable.
Summary of the invention
The technical problem that the present invention will solve provides a kind of noise reduction good purification, diesel exhaust purifying box with low cost.
For solving the problems of the technologies described above technological scheme of the present invention be: a kind of diesel exhaust purifying box, comprise case lid, casing, suction tude and outlet pipe, said case lid and casing are tightly connected through sealing gasket and fastening piece, and outlet pipe is fastened on the case lid; Casing one side bottom is provided with the drain opening of band plug screw, and the top of the drain opening of band plug screw is provided with the water intake of band plug screw, fills with the lime water of clarification between the drain opening of the water intake of the band plug screw in the casing and band plug screw; The zigzag suction tude is made up of the lower transverse tubule that the upper lateral tube, vertical tube and the cylndrical surface that are communicated with one are provided with air outlet hole; The cylndrical surface is provided with the lower transverse tubule horizontal setting of air outlet hole in the lime water of bottom half, is positioned at the side that the upper lateral tube level of case lid below is stretched out casing.Between the top edge of water intake of band plug screw, horizontal setting is provided with the water-stop sheet of air hole in upper lateral tube below said case lid and the casing, the port of said outlet pipe in casing be positioned at water-stop sheet above.
The invention has the beneficial effects as follows:
1. the waste gas that diesel engine is discharged mainly contains: CO, CO2, HC, NOX, SO2, soot particle, filter through the neutralization of lime water [Ca (OH) 2], the CO2 in the waste gas, SO2 and soot particle are dissolved in or are deposited in the water, and noise also weakens greatly.
2. the present invention is simple in structure, cheap, and the cost of periodic replacement lime water is also very low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the plan view of Fig. 1.
Embodiment
Embodiment 1Shown in Fig. 1-3: a kind of diesel exhaust purifying box, case lid 2 is connected through sealing gasket 5 and bolt seals with casing 6,, outlet pipe 1 is fastened on the case lid 2; Casing 6 one side bottom are provided with the drain opening 8 of band plug screw, and the top of drain opening 8 is provided with the water intake 9 of band plug screw, fill with the lime water 7 of clarification between water intake 9 in the casing 6 and the drain opening 8; Zigzag suction tude 4 is made up of the lower transverse tubule that the upper lateral tube, vertical tube and the cylndrical surface that are communicated with one are provided with air outlet hole, and the lower transverse tubule horizontal setting is in the lime water 7 of casing 6 bottoms, and the upper lateral tube level that is positioned at case lid 2 belows is stretched out a side of casing 6.Between the top edge of water intake 9 of band plug screw, horizontal setting is provided with the water-stop sheet 3 of air hole in upper lateral tube below said case lid 2 and the casing 6, the port of said outlet pipe 1 in casing 6 be positioned at water-stop sheet 3 above.
The upper lateral tube of suction tude 4 is communicated with the diesel engine vent gas pipe; Diesel exhaust is provided with air outlet hole through upper lateral tube, vertical tube and the cylndrical surface of zigzag suction tude 4 lower transverse tubule gets in the lime water 7; Neutralization through lime water [Ca (OH) 2] is filtered; CO2 in the waste gas, SO2 and soot particle are dissolved in or are deposited in the water, and noise also weakens greatly; Residual air is discharged through the air hole of water-stop sheet 3 and the outlet pipe of water-stop sheet 3 tops; The lime water surface in when water-stop sheet 3 helps to stablize the diesel-engine road vehicle operation in the exhaust gas purification case.Exhaust gas purification case should regularly be uncapped and cleaned and change inexpensive lime water.
