Description
Technical Field
The utility model relates to an engine exhaust system technical field, concretely relates to low noise sound deadening system with tail gas purification function.
Background
With the development of economy, the national requirements on the environment are continuously improved, and the national standards 2 and 3 are successively developed. The exhaust system of the common diesel generating set is only provided with a conventional silencer, the silencer only can reduce the exhaust noise of the set, and the silencer cannot purify harmful gas exhausted by the diesel engine through combustion work. The national relevant standards for the environment are difficult to achieve, and the pollution to the environment is increasingly shown. During operation, diesel engines generate a large amount of harmful gases such as soot (PM), carbon monoxide (CO), and Hydrocarbons (HC). Not only seriously pollutes the environment, but also causes great harm to the health of operating personnel. The environment is polluted by the large accumulation of soot Particles (PM), wherein the carbon particles can be inhaled by the human body (mainly PM10) and even enter the lung of the human body (mainly PM2.5), and the health of the operator is affected. The direct emission can not meet the national relevant smoke emission standard.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome foretell not enough, provide a low noise sound deadening system with tail gas purification function.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
a low-noise silencing system with a tail gas purification function comprises an exhaust pipe, a tail gas purifier and an impedance silencer which are sequentially communicated, wherein the tail gas purifier comprises a ceramic filter, and an oxidation type catalyst is arranged in the ceramic filter;
a smoke exhaust pipe is arranged between the tail gas purifier and the impedance silencer, and a black smoke purifier is arranged inside the smoke exhaust pipe;
a bypass pipe is arranged on one side of the tail gas purifier, and a valve is arranged on the bypass pipe;
the periphery of blast pipe, tail-gas clean ware and impedance silencer all is equipped with fixed subassembly, and fixed subassembly includes two clamp rings, and the one end of every clamp ring is equipped with an opening, and clamp ring open-ended one end is equipped with a fixed block, and equal threaded connection has a double-screw bolt on every fixed block, and two double-screw bolts are connected with a bolt head jointly, and every double-screw bolt passes a base plate, and two base plates are fixed on a mount jointly.
Because the exhaust temperature of the exhaust port of the diesel engine is about 400-500 ℃, the tail gas purifier is internally provided with a ceramic filter, and an oxidation type catalyst mainly comprising platinum is arranged in the tail gas purifier, the platinum has good SO2 resistance, and the self-recovery function is good and is not easy to be poisoned. Principle of oxidation type chemical reaction:
CO+1/2O2→CO2；4HC+5O2→4CO2+2H2O；C+O2→CO2。
the main purpose of the oxidation catalyst using platinum as a main component is to reduce the emission of Hydrocarbons (HC), carbon monoxide (CO) and a part of Particulate Matter (PM). Although soot in the PM is hardly oxidized by it, it can very effectively oxidize soluble organic matters (SOF) in the PM. Further, HC and CO can be reduced again. The oxidation principle is basically the same as that of HC and CO oxidized by a three-way catalyst of a gasoline engine. And can purify harmful components (such as polycyclic aromatic hydrocarbon, acetaldehyde and the like) which are not limited by current regulations. The method can reduce the toxic HC part by 75-90%, CO by 75-90%, PM by about 20%, the emission of polycyclic aromatic hydrocarbons by 60% and acetaldehyde by 70%.
Among the fixed subassembly, the bolt head control two double-screw bolts can and take place the transmission between two fixed blocks for carry out relative movement between two fixed blocks, thereby make the opening of clamp ring open or close, realize installing or dismantling blast pipe, tail-gas clean-up ware or impedance silencer.
Preferably, an exhaust elbow is arranged between the exhaust pipe and the tail gas purifier.
Preferably, the oxidation catalyst is an oxidation catalyst based on platinum.
Preferably, the valve is a manual butterfly valve.
Preferably, two studs in the same fixing assembly are arranged in mirror image.
The utility model has the advantages that: in this low noise sound deadening system with tail gas purification function, tail gas purifier has been added, and tail gas purifier adopts the ceramic adsorption principle, chooses oxidation type catalyst for use to purify, moreover, including fixed subassembly can make entire system nimble dress on the mount, has realized the nimble dismantlement of system.
