Abstract
The utility model relates to a purifying device for exhausting smoke arranged between the exhaust manifold of an engine and a muffle. The utility model is characterized in that at least a purification connecting pipe, a warm-up temperature control unit and a dangled back pressure control unit are included. The ceramic catalysers inside the purification connecting pipe are distributed in the shape of a honeycomb and form a plurality of ceramic compartments and a plurality of monodirectional punchthrough porous channels are formed in the compartments. The punchthrough ends of every two adjacent porous channels are arranged oppositely and noble metal is plated on the edge surface of the ceramic compartments. When the temperature of the ceramic compartment of exhaust air is raised to be over the catalytic burning point (approximately 300 degrees Celsius system), the ceramic compartment can conduct a proper chemical reaction with the noble metal through the oxide that the ceramic compartment has itself and the harmful particles are leaded to be discharged through the punchthrough ends of the two adjacent porous channels after the harmful particles produce the effect of barrier burnout, thereby improving the purifying effect greatly. The warm-up temperature control unit and the dangled back pressure control unit are arranged on one side of the purification connecting pipe. The warm-up temperature control unit and the dangled back pressure control unit can maintain the optimal treating temperature and pressure state. The purifying effect of the purification connecting pipe is not affected by an extremely low temperature or non-loaded extrinsic factors and thus has practicability.
Description
Technical Field
The utility model relates to a purifier, in particular to can effectively eliminate purifier that discharges fume of harmful substance in the air.
Background
Engines in general, particularly diesel engines, often emit exhaust gases (e.g., carbon monoxide (CO), Hydrocarbons (HC), and Nitrogen Oxides (NO) with dramatic toxicity levels during usex) Sulfur Oxide (SO)x) Black Smoke (SOOT), suspended Particulate (PM), etc.), wherein:
(1) carbon monoxide (CO), which is highly toxic, colorless and odorless, and thus can cause people to be dizzy and fatal when being in a concentration of 800ppm for 2-3 hours (namely, the human hemoglobin can rapidly block oxygen transportation in blood), so that the number of carbon monoxide (CO) poisoning events is always ranked higher in the whole united states (generally, the carbon monoxide (CO) poisoning events have about 800-3000 ppm in exhaust gas discharged from a diesel engine) in the ranking of death due to inhalation of toxic gas in the us death report in the past; when combined with oxygen molecule, it will generate greenhouse effect and form acid rain after combined with water molecule ) And has influence on the growth of crops.
(2) Hydrocarbons (HC), generally about 300-2000 ppm different in exhaust gas discharged from diesel engines, are mainly hydrocarbons (C)nH2n+2，CnH2n-2) It will react with O, NO or O3The reaction produces toxic substances in the smoke, such as: benzene (C)6H6) Biphenyl (C)12H10) It is a carcinogenic substance, and is liable to enter human body with air to produce lung cancer, liver cancer and other symptoms.
(3) Carbon oxides (NO)x) Generally, the amount of NO in the exhaust gas discharged from a diesel engine is about 500 to 2500ppm, wherein the amount of NO is2Will diffuse to the upper troposphere and absorb ultraviolet light to decompose ，[O]、O2The smoke can react with smoke to generate light smoke with a plurality of harmful substances attached to dust, and scattered light is absorbed to reduce visibility, so that black lung disease is caused; laughing gas (N)2O) has the function of anesthetizing nerves, and is easy to cause senile dementia.
(4) Carbon oxides (SO)x) Which is a necessary component of oil, stimulates respiratory tract, resists twigs and corrodes houses, and has corrosive SO3And H2After the O is combined, acid rain can be formed to influence the growth of crops.
(5) Although not as toxic as carbon monoxide (CO) and Hydrocarbons (HC), black Smoke (SOOT) is still a difficult suffocation, and thus many building generators are fire fighting and standby equipment, which should be maintained at least once a month, but they are not suitable for maintenance and commissioning due to the sequelae mentioned above.
(6) The suspended Particulate Matter (PM) is smaller and lighter than black smoke particles and is difficult to see by naked eyes, and when the PM is spread in air, the PM can be stopped on the skin of a human body to cause itching and intolerance, or can enter the lung of the human body along with the air to cause damage, and generally the PM has the range of 500-2500 ppm in the exhaust gas discharged by a diesel engine.

however, the above exhaust purifier usually needs to be provided with a bypass pipe to discharge the filtered exhaust gas through the bypass pipe, so that it still causes secondary pollution to the environment, and if the engine generator is used less, the purifier is installed in a low temperature environment, or there is no space to be installed close to the engine, and the filtering and purifying effect is greatly reduced when the high temperature cannot be maintained, the above pollution problem still cannot be eradicated; the disadvantages are summarized below:
1. the influence of harmful gases on the environment cannot be effectively eliminated;
2. the danger of headache, vomit, dizzy and even death of people caused by excessive carbon monoxide content around the human body is easy to happen;
3. the waste gas is recovered by a bypass pipe, so that secondary pollution is easily caused;
4. the filter is easily influenced by the environment, so that the filtering effect is greatly reduced because the pipeline cannot reach the preset temperature;
therefore, how to overcome the above disadvantages is the technical difficulty that the present inventor intends to solve.
In view of this, the inventor has brought the utility model to birth through many times of breakthrough and improvement based on his own professional literacy and technical idea.
