Abstract
The invention discloses a high temperature insulation and temperature increasing device of tail gas of a diesel engine. The device is characterized by comprising a double-layer barrel body, a tail gas inlet and a temperature detection device, the double-layer barrel body comprises an outer barrel and an inner barrel, the inner barrel is arranged in the outer barrel, ceramic fibers are filled between the inner barrel and the outer barrel, the tail gas inlet is formed in the side face of the inner barrel, and the temperature detection device mainly is a temperature sensor which extends into the inner barrel. Due to the fact that the tail gas of the diesel engine is contained in the inner barrel, when a certain amount of the tail gas is accumulated, part of fuel is conveyed into the inner barrel through a communication pipeline between the inner barrel and the outer barrel, and accordingly the tail gas is burnt in a secondary mode. Due to the fact that the ceramic fibers having the heat preservation function are filled between the outer barrel and the inner barrel, the heat of the inner barrel is preserved, an obvious heating function is achieved, and the tail gas can be fully burnt in the secondary mode. Meanwhile, the temperature of the inner barrel can be monitored in a real-time mode through the temperature sensor extending into the inner barrel, and convenience is brought to keep observing conditions in the inner barrel.
Description
Technical field
The present invention relates to a kind of diesel engine vent gas high temperature insulating and warming device, especially a kind of using effect is good, diesel engine vent gas high temperature insulating and the warming device of environmental protection.
Background technique
Since coming out, diesel engine relied on its good power character, Economy and durability to be widely used in various power plant, boats and ships and vehicle, so far it is still the highest heat engine of the thermal efficiency, the diesel-oil vehicle growth momentum is swift and violent, and China's estimation diesel-oil vehicle in 2010 recoverable amount reaches 1,200 ten thousand.But along with the increase of diesel engine quantity and the enhancing of people's environmental consciousness, diesel engine becomes increasingly conspicuous to the pollution problem of air, the main component in the diesel engine vent gas and being distributed as: water vapour 2.60%, 7.1%,
15%,
75.21%, other micro constitutents comprise that particulate matter accounts for 0.09%, and
, not combustion,
,
Sulphate, aldehyde and ammonia etc., wherein particulate matter mainly comprises hard carbon (soot), or be called and dissolve part (insol or IOF), liquid phase hydrocarbon (HC), or be called solubilized organic principle (SOF) or volatilizable organic principle (VOF) and adsorb on it on a small quantity
And sulphate.People think at first, diesel particulates only influences visibility, along with deepening continuously of research, its harmfulness is understood by people gradually, some researchs have confirmed that exhaust gas particulate can cause chronic disease, the evidence of EPA (EPA), SOF has mutagenesis, its component be carcinogen more than 90%, feel that the particle diameter of most of exhaust gas particulates between 0.01 ~ 1.0 μ m, can be suspended in the atmosphere for a long time, be easy to enter alveolar and deposit by respiratory system, than small particle even can enter in the blood, very big to the threat of health.But at present not at this piece of vent gas treatment, vent gas treatment thoroughly just directly is not discharged in the atmosphere, has buried potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention provides a kind of diesel engine vent gas high temperature insulating and warming device, has that using effect is good, the characteristics of environmental protection.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of diesel engine vent gas high temperature insulating and warming device, its innovative point is to comprise: the pair of lamina cylindrical shell, be specially urceolus and inner core, described inner core places urceolus, and is filled with ceramic fiber between the two, the inner core left side is welded on the urceolus left side, described inner core right side is provided with unicom pipeline, and described unicom pipeline end exceeds the urceolus right side, and described urceolus is welded with the filter flange on the right side; One tail gas suction port, described tail gas suction port is arranged on the inner core side, is provided with transition conduit between tail gas suction port position, described inner core side and urceolus, and described transition conduit end exceeds the urceolus side; One temperature-detecting device, described temperature-detecting device is mainly the temperature transducer that puts in the inner core.
Further, described inner core is circular cone structure, and its right side diameter is less than the left side diameter.
Further, described temperature transducer is arranged at directly over the inner core, near position, inner core left side.
Further, the periphery that described unicom pipeline exceeds urceolus right side part is provided with oil drain out, and described oil drain out links to each other with the recovery fuel tank.
The invention has the advantages that: by diesel engine vent gas is accommodated in the inner core, when accumulating to when a certain amount of, by the unicom pipeline between inner core and urceolus part of fuel is delivered in the inner core, thereby tail gas is carried out secondary combustion; And owing to be filled with the ceramic fiber of insulation effect between urceolus and inner core, thereby inner core is carried out an insulation, play an effect of obviously heating, thereby make tail gas be able to abundant secondary combustion, also can utilize the temperature transducer that puts in the inner core that the temperature of inner core is monitored in real time simultaneously, be convenient to constantly observe the situation in the inner core.
With close its large end face directly over the inner core of temperature transducer setting and circular cone structure, thereby the data that temperature transducer is measured are more accurate.
The periphery that unicom pipeline exceeds urceolus right side part is provided with oil drain out, and oil drain out is linked to each other with the recovery fuel tank, thereby regulates the amount for the fuel of exhaust combustion, and unnecessary fuel is recycled.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Diagram is the structural representation of a kind of diesel engine vent gas high temperature insulating of the present invention and warming device.
Embodiment
