Abstract
The utility model relates to a tail gas silencing and purifying device for internal combustion engines. A hydrogen generating reactor connected with a tail gas inlet is arranged on a shell body of the tail gas silencing and purifying device. After being heated by tail gas, liquid in an evaporating pipe is gasified. Hydrogen generated by a catalyst bed enters a combustion chamber of an internal combustion engine so that the hydrogen is mixed and combusted. In addition, a tail gas dividing pipe is arranged in the shell body. The utility model with simple structure can reduce the exhaust of harmful gas and heat and reduce noises. The utility model is suitable for various internal combustion engines.
Description
The utility model relates to a kind of exhaust gas purifier for IC engine.
At present, the pollution of internal-combustion engine mainly is divided into three kinds: 1, waste gas; 2, noise; 3, thermal radiation; Existing many improvement all are at baffler itself, and ignored getting in touch between baffler and the internal-combustion engine, thereby improved effect has been subjected to restriction, present people have found to mix annealing in hydrogen atmosphere gas and can improve combustion condition in burner, reduce the discharge capacity of harmful gas, this provides solution route to the problems referred to above undoubtedly.
The purpose of this utility model is to provide a kind of tail-gas purifying muffler for internal combustion engine, it can utilize the waste heat of tail gas, generation hydrogen offers in the combustion chambers of internal combustion engines and burns, thereby and tail gas is changed the flow direction by this device the time and flow velocity, volumetric expansion reach erasure effect.
The purpose of this utility model realizes in the following way:
This baffler has the housing (1) of a sealing, the two ends of housing (1) are respectively equipped with suction tude (2) and outlet pipe (10), wherein in housing (1), also have a hydrogen-manufacturing reactor (3), suction tude (2) communicates with hydrogen-manufacturing reactor (3) exocoel, hydrogen-manufacturing reactor (3) has a liquid inlet pipe (4) and a hydrogen steam outlet pipe (8), liquid inlet pipe (4) one ends pass housing (1) the other end and connect the evaporating pipe (5) that many rows be arranged in parallel, and the outlet of evaporating pipe (5) connects a catalytic bed (6).
Suction tude (2) is also divided in housing (1) and is connected to ram's horns (9) in addition.
During work, exhaust gases of internal combustion engines enters the hydrogen-manufacturing reactor exocoel and to its heating, the catalytic bed on the catalytic bed is heated, and the liquid in the evaporating pipe is vaporized simultaneously, the gas of this vaporization is cracked into hydrogen by catalytic bed, enters in the combustion chambers of internal combustion engines through hydrogen outlet and mixes burning with oil plant.
The utility model compared with prior art has following advantage:
1, hydrogen is sent into IC engine blend-burning and can be established kind its combustion condition, sufficient combustion also reduces the discharge capacity of harmful gas.
2, the process of hydrogen manufacturing is an endothermic process, the exhaust emissions heat absorption can be utilized.Reduce thermal radiation, be beneficial to environmental protection.
3, tail gas is shunted by ram's horns, change flows to flow velocity, makes volumetric expansion, can reduce noise effectively.
4, hydrogen-manufacturing reactor is installed in the baffler, and compact structure, volume are little, is beneficial to existing locomotive repacking.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model structural drawing
In Fig. 1: (1) housing; (2) suction tude; (3) hydrogen-manufacturing reactor; (4) liquid inlet pipe; (5) evaporating pipe; (6) catalytic bed; (7) outlet; (8) hydrogen steam outlet pipe; (9) ram's horns; (10) outlet pipe.
In an embodiment, suction tude (2) also connects a ram's horns (9) tail gas and enters in the hydrogen-manufacturing reactor (3), channel box type evaporator is heated, hydrogen-manufacturing reactor is a prior art, can adopt pure class I liquid I and ketone group catalyzer to generate hydrogen, quantitatively inject alcohols (as methyl alcohol) raw material from liquid inlet pipe (4), be heated when arranging evaporating pipe more and be vaporized through, enter catalytic bed (7) and produce hydrogen by outlet (7), enter combustion chambers of internal combustion engines by hydrogen steam outlet pipe (8) again and mix burning, a tail gas part is used for the heating to hydrogen-manufacturing reactor, and another part shunting is all discharged through outlet pipe.
Claims (2)
1, a kind of tail-gas purifying muffler for internal combustion engine, the housing (1) that has a sealing, the two ends of housing (1) are respectively equipped with suction tude (2) and outlet pipe (10), it is characterized in that in housing (1), also having a hydrogen-manufacturing reactor (3), suction tude (2) communicates with hydrogen-manufacturing reactor (3) exocoel, hydrogen-manufacturing reactor (3), have a liquid inlet pipe (4) and a hydrogen steam outlet pipe (8), liquid inlet pipe (4) one ends pass housing (1), and the other end connects the evaporating pipe (5) how row be arranged in parallel, the outlet of evaporating pipe (5) connects a catalytic bed (6).
2, baffler according to claim 1 is characterized in that suction tude (2) is also divided to be connected to ram's horns (9) in housing (1).
