Abstract
The present invention provides a highly efficient exhaust gas purification renewable muffler of diesel engine, it is characterized in that the adoption of renewable efficient infrared replacing precious metal catalyst particle ceramic honeycomb catalytic purification devices, the advantage is a high adsorption and specific wavelength infrared radiation for high-efficiency purification Diesel exhaust capacity, and the gas exhaust purification muffler of Diesel can automatically be renewed and possesses anti-aging, long service life, the elimination of exhaust noise, simple structure, produced convenience and low cost, which is a more ideal and economical, practical efficient .
Description
Technical field:
The present invention relates to a kind of diesel engine vent gas and purify silencer, concrete is a kind of diesel-engine self-regenerated efficient tail-gas purifying silencer.
Background technique:
Because diesel engine is different with the working procedure and the combustion condition of petrol engine, the composition of exhaust is different, and the three-effect catalysis that is used for purifying exhaust of petrol engine is inapplicable on diesel engine vent gas is administered, and diesel engine vent gas improvement does not at present still have comparatively ideal purification plant.
The invention provides a kind of diesel-engine self-regenerated efficient tail-gas purifying silencer, be to purify silencer from regeneration at a kind of efficient infrared of diesel engine condition design, it is characterized in that adopting efficient infrared from regenerated granule replacement noble metal catalyst honeycomb ceramic catalyze purification plant, its advantage is the ability that infrared rays with very high absorption and radiation specific wavelength is used for high efficiency purification diesel engine tail gas, and energy automatic regeneration, anti-aging, long service life, eliminate exhaust sound simultaneously, and it is simple in structure, easily manufactured, cost is low, is a kind of more satisfactory and not only economy but also practical diesel engine vent gas had purified efficient purifying muffler.
Concrete technological scheme of the present invention:
Diesel-engine self-regenerated efficient tail-gas purifying silencer of the present invention is by the purifying muffler cylindrical shell, and mesh plate is formed from regenerated granule three parts.
Purifying muffler cylindrical shell of the present invention is made up of leading portion, stage casing, back segment three parts; Leading portion is tail gas import (1), and flange, flanged pipe that is connected with Diesel Engine Exhaust Pipe and the flaring pipeline that is connected with the purifying muffler stage casing are arranged; The stage casing is purifying muffler groundwork chamber, and its cross section can be a cylindrical shape, also can be oblate tubular or oval cylinder; Back segment is made up of convergent pipeline and tail gas outlet (6); The material of cylindrical shell is high temperature resistant, anticorrosive, aging-resistant stainless steel or alloyed steel; Mesh plate of the present invention is by big orifice plate and the aperture filter screen is superimposed forms, and the hole is circle, long-round-shape, square, rectangular, rhombus or corrugated, and material is high temperature resistant, anticorrosive, aging-resistant stainless steel or alloyed steel; Of the present invention is a kind of resistant to elevated temperatures inorganic material quartz sand particle from regenerated granule, and its main component is SiO more than 92%
2, the size of particle is at 2～8 millimeters, has high-strength absorption and the ultrared characteristic of radiation specific wavelength and anti-sulphur, anti-aging, corrosion resistance.
Diesel engine vent gas adopts from efficient purification of regenerated granule and is better than honeycomb ceramic carrier and noble metal platinum, rhodium, palladium catalyst, big from the regenerated granule specific surface area, tail gas by the time in its slit, pass, touch opportunity is many, not only increase substantially purification efficiency, and can not produce obstruction and inefficacy, use Q-percentile life permanent.
The present invention is further described below in conjunction with accompanying drawing and example.
Fig. 1 is the diesel-engine self-regenerated efficient tail-gas purifying silencer sectional arrangement drawing.
As shown in Figure 1:
1. tail gas import 2. purifying muffler cylindrical shells
3. mesh plate 4. purifies particle from regeneration
5. purifying chamber's 6. tail gas outlet
The contrast accompanying drawing, describe the diesel-engine self-regenerated efficient tail-gas purifying silencer working procedure in detail:
Diesel engine vent gas enters purifying muffler from import (1), pass mesh plate (3) after, the air-flow of tail gas passes and fully contact with it from regeneration certainly purifies the slit of particle (4); Purify particle (4) from regeneration and be made up of highly purified quartz sand particle, main component is SiO
2Has very strong specific wavelength frequency spectrum infrared radiation characteristic and anti-sulphur, ageing resistance, when tail gas passes through the filtration that purifies particle (4) with regeneration certainly with contact, purify particle (4) the at first particulate matter and the exhaust gas heat of absorption tail gas from regeneration, generate the black carbonized film in surface action, and promote the temperature of self and the infrared rays of emission specific wavelength frequency spectrum, tail gas has been accepted behind the infrared rays of regenerated granule (4) emission, further improved temperature, and make carbon microsphere in the tail gas, inflammable matter and the black carbonized film generation combustion oxidation reaction on regeneration purification particle (4) surface certainly, in the time of reaction, further improved temperature again, make the purifying muffler inner barrel reach higher temperature very soon, under this high temperature and radiation environment, be enough to make combustible component (soot particle) combustion oxidation in the tail gas and make harmful components (CO, HC, HOx) etc., by a series of oxidation and reduction reaction, become stable material, thereby reach the purpose of cleaning of off-gas, discharge from tail gas outlet (6) through the tail gas of purified treatment; Tail gas when passing in the slit that purifies particle (4) of regenerating certainly air-flow is disperseed and buffer stream is moved, and has just eliminated exhaust sound simultaneously.
