Description

The noise reduction filtering purification plant of engine emission waste gas

The utility model relates to a kind of device of purifying exhaust air, refers to the burned purification plants of institute's discharging waste gas afterwards of oil firing such as a kind of diesel oil, particularly is suitable for the noise reduction filtering purification plant that vehicle, factory etc. locate the engine emission waste gas of use.

As everyone knows, oil is to come from the hydrocarbon system that plant and animal residue becomes multiple different volatility, a spot of oxygen, nitrogen, the complex mixture of sulphur material and ash branch, crude oil is through after refining, can enough obtain automobile, train, gasoline and diesel oil that places such as factory need, though all need through the multiple step poly-when extracting gasoline or diesel oil, to remove ash content, sulphide, nitride, the material of resinousness and the obstacle materials such as compound of polymerization, but, in fact, above-mentioned obstacle material all can't absolutely be removed, and in gasoline that refines gained or diesel oil existence is arranged all still.Except gasoline or diesel oil itself contain the reason of obstacle material, up to now, the shortcoming of combustion engine because of overcoming on designing and making, make gasoline or diesel oil can't reach the condition of perfect combustion, so gas beyond the combustion engine of discharging, not only contain the carbon of volume and become black smoke, contain harmful poisonous gass such as the carbon monoxide that do not fire alkane fully, nitrous oxide, nitrogen dioxide, sulfur dioxide, carbon compound in addition.Wherein, carbon monoxide territory sulfur dioxide is particularly serious to the murder by poisoning of human body, point out according to world health data that mechanism delivers, the nitrogen oxides that is contained among the engine exhaust, carbon monoxide and sulfur dioxide, after being inhaled among the human body, make diseases such as people have a headache, dizziness, laryngalgia, asthma, cancer easily, and cancer and the other diseases nowadays found in the world, the gesture of rising is day by day just being arranged owing to the dirty and noxious person of causing (the especially disease of respiratory tract organ) of engine exhaust.

The waste gas that fuel oil such as diesel oil or gasoline is discharged, not only the people is known from experience and damage, also can cause damage for crops, this fact can be shown by the data of abroad delivering, the office of preventing points out according to the California, USA pollution of atmosphere: this state is because atmospheric pollution, so that the suffered infringement of crops, statistics reaches to count and picks up hundred million dollars between 1 year, and its loss is not little!

Because the pollution that the burning waste gas that fuel oil discharged causes has caused the atmospheric pollution of human whole living environment, the raising of noise pollution and temperature, therefore, scientists is that the utmost point is thought solution, drop into great amount of manpower, material resources, financial resources, but, its invention all is towards the direction that fuel oil is burnt again, so the invention of the suitable Catalytic Converter of gasoline car is just arranged, but, diesel engine can't mat the work catalyst transform to clamor and handle, and essential nationality work gas or other fuel could reduce dirty seven with exhausting recombustion, but, the method that this kind reduce to pollute, not only dangerous, also consumes energy again.

Because present vehicle and factory's discharging waste gas cause the air-polluting situation very serious, the inventor after deliberation and the invention of Taiwan patent No. 83102387 " the noise reduction filtering purification plants of engine emission waste gas ", only this creation is not attained as yet in perfection, and the inventor makes persistent efforts, and this preceding case is improved again, and the generation of second case is arranged, this case patent applied for is numbered the Taiwan patent No. 83212613, and obtains and check and approve, modern claimant continues research again and improves, and asks its supreme good.

Main purpose of the present utility model is to provide a kind of noise reduction filtering purification of engine emission waste gas to put, use the poison gas of removing in the waste gas that engine combustion gasoline, diesel etc. discharged, the chance that makes people absorb poison gas greatly reduces, therefore the chance that catches also is minimized, in this way, because the air of breathing comparatively cleans, the health condition of health more shape is promoted.

Except removing the toxin of motor row in waste gas, device of the present utility model still can be removed the sound that is sent when look is deceived imperfect combustion charcoal and combustion gas in the waste gas, reduce the temperature of discharging waste gas simultaneously, therefore, another purpose of the present utility model is to promote the purification of environment and noise-decreasing, temperature to injury that people caused.

For reaching above-mentioned purpose, the noise reduction filtering purification plant of engine emission waste gas of the present utility model includes a water tank and an air-guide air-exhaust sound-absorptive purifying tube; Within the air-guide air-exhaust sound-absorptive purifying tube, separate with dividing plate become a suction chamber, two air guides remove smoke-box, two noise reduction purifying chambers, two bleed chambers and eight spaces such as exhaust chamber, be characterized in: air guide removes the tilting guide plate of smoke-box front end and forms airtube, air guide removes smoke-box and communicates with the noise reduction purifying chamber, the noise reduction purifying chamber is multiple to communicate with the bleed chamber, and noise reduction purifying chamber and air guide remove fiberfill fibers velvet in the horizontal segment of smoke-box; Water tank bottom, draw the noise reduction purifying chamber of aqueduct towards air guide noise reduction purifying tube, the end outside communicated with water tank upper with a body before air guide removed smoke-box, air guide removes smoke-box and draws an effluent discharge pipe, the noise reduction that reaches engine emission waste gas purifies and its mechanism of Rapid Cleaning simultaneously, keeps its function.Between suction chamber and suction tude, exhaust chamber and outlet pipe, all directly communicate, in the middle of two full noise reduction purifying chambers are positioned at, two suction chamber upper angled and descending, air guide removes smoke-box and the noise reduction purifying chamber is equipped with through hole, the bleed chamber communicates with exhaust chamber with noise reduction purifying chamber, bleed chamber, be provided with aqueduct at water tank and noise reduction purifying chamber, the suction tude of water tank head and engine exhaust pipe or air-guide air-exhaust sound-absorptive purifying tube is provided with an air pipe, on air pipe, aqueduct, intake pipe and discharge pipe, be respectively equipped with a valve body.

The utility model has the advantages that, the noise reduction filtering purification plant of engine emission waste gas, useless poison gas when the discharge of engine exhaust emission source, through the effect that circuitous turnover enters the multi-layer fiber medium in noise reduction purifying chamber and the smoke abatement exhaust air chamber, reach harmful particle and essence in the noise of eliminating combustion gas and the filtering combustion gas.The utility model is provided with water tank, and water tank and noise reduction purifying chamber are provided with aqueduct and valve body, and the purifying chamber is cleaned to noise reduction.The utility model can be applicable to the noise reduction filtering and the purification of multiple toxic emission source institute discharging waste gas, is not limited to diesel engine.The utility model really can reduce atmospheric pollution, ensures people's health.
