Abstract
The utility model relates to a waste-gas purifying box of a diesel engine. A box cover is in sealing connection with a box body by sealing gaskets and fasteners; an exhaust pipe is tightly fixed on the box cover; a water discharging port with a screw plug is arranged at the bottom of one side surface of the box body; a water inlet with a screw plug is arranged on the water discharging port; clear lime water is filled between the water inlet and the water discharging port in the box body; a Z-shaped gas inlet pipe consists of an upper cross pipe, a vertical pipe and a lower cross pipe with a cylindrical surface provided with gas outlet holes; the lower cross pipe is horizontally arranged in the lime water at the bottom of the box body; the upper cross pipe positioned below the box cover extends out of one side surface of the box body horizontally; a water baffle with ventilating holes are horizontally arranged between the upper cross 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 baffle. Waste gas exhausted by the diesel engine is neutralized and filtered by the lime water, and the waste gas and soot particles are dissolved or precipitated in water, so that the noise is also weakened greatly; and the waste-gas purifying box is simple in structure and low in cost, and the cost for periodically replacing the lime water is also low.
Description
Technical field
The utility model relates to a kind of tail gas purification device of combustion engine, particularly a kind of diesel exhaust purifying box.
Background technique
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 utility model will solve provides a kind of noise reduction good purification, diesel exhaust purifying box with low cost.
For the technological scheme that solves the problems of the technologies described above the utility model is: 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 beneficial effect of the utility model is:
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 utility model 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 utility model is further specified.
Fig. 1 is the structural representation of the utility model.
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.
