Description

Start heating exhaust purifier

Technical field

The utility model relates to a kind of startup and heats exhaust purifier.

Background technology

Automobile exhaust pollution has become the main source of topsoil, and within for some time from now on, fuel-engined vehicle will be the main product of automotive industry. Paying much attention to the research work of purifying vehicle exhaust technology in recent years both at home and abroad, high strength of the prior art, high temperature oxidation resisting foamed conducting ceramic material have been applied in refining plant. But owing to its low temperature active is poor, combustion initiation temperature is higher, when thus causing cold-starting automobile, tail gas clean-up effect is poor.

For the problems referred to above, publication number is that the patent document of CN201461044U discloses a kind of tail gas cleaner for motor-driven vehicle, and its technical scheme is: comprise shell, also comprises well heater, containing the scavenging agent of nickel oxide and nickel sesquioxide and glass fibre; Well heater adopts far infrared rays silica tube, is contained in the central authorities of shell, and glass fibre is contained in whole shell in space, and scavenging agent powder filling is in the space of glass fibre.

In the technical scheme of above-mentioned patent document, being heated by scavenging agent by well heater so that when cold-starting automobile, the molecule participating in reaction arrives activation energy threshold value, and tail gas can be purified. But, owing to well heater does not arrange auto-switch, when automobile normally runs, when exhaust temperature enough makes molecule occur to react, well heater continuation work, wastes the energy.

Practical novel content

The utility model is intended to provide a kind of and starts heating exhaust purifier, so that during automobile starting, catalyzer can be heated by well heater, when automobile normally runs, well heater stops heating, and heat and catalyzer by tail gas self react.

Startup heating exhaust purifier in this scheme, base case is: comprise tail gas clean-up room, described tail gas clean-up indoor are filled with catalyzer, one end of described tail gas clean-up room is connected with inlet pipe, described inlet pipe inwall is provided with temperature sensor, the other end of described tail gas clean-up room is connected with vapor pipe, also comprise well heater, described well heater is cylindrical, described well heater is horizontally installed on tail gas clean-up indoor, one end of described well heater is stretched out from tail gas clean-up room sidewall, one end that described well heater stretches out tail gas clean-up room is connected with controller, described temperature sensor is connected with controller.

Principle of work and useful effect: during automobile starting, well heater starts thereupon and is heated by catalyzer, although vehicle exhaust temperature is lower, but the effect due to well heater so that catalyzer can reach activation temperature, is heated by vehicle exhaust. Unlike the prior art, after automobile normally runs, vehicle exhaust temperature raises, the temperature needed for catalyzed reaction can be reached, now, owing to being provided with temperature sensor at inlet pipe inwall, and one end that well heater stretches out tail gas clean-up room is connected with controller, and temperature sensor is connected with controller. Temperature sensor is by signal transmission to controller, and controller control well heater stops heating. So, this scheme is energy heatable catalyst when automobile starting, can stop well heater when automobile normally runs, save the energy.

Scheme 2, as the improvement to base case, described tail gas clean-up room is cylindrical. Advantage is, convenient installation on automobile chassis.

Scheme 3, as the improvement to scheme 2, described inlet pipe and vapor pipe are arranged on the middle part of two bottom surfaces of cylindrical tail gas clean-up room. Advantage is, can ensure the uniformly and effectively purification of tail gas in tail gas clean-up indoor.

Scheme 4, as the improvement to scheme 3, described well heater is at least two. Advantage is, it is to increase the heats of well heater.

Scheme 5, as the improvement to scheme 4, described well heater is arranged in the indoor radial symmetry of tail gas clean-up. Advantage is, catalyzer is heated uniformly and effectively.

Accompanying drawing explanation

Fig. 1 is the structural representation that the utility model starts heating exhaust purifier embodiment.

Embodiment

Below by embodiment, the utility model is described in further detail:

Reference numeral in Figure of description comprises: inlet pipe 10, temperature sensor 11, controller 20, well heater 30, tail gas clean-up room 40, vapor pipe 50.

Embodiment

As shown in Figure 1, start heating exhaust purifier, scheme is: comprise tail gas clean-up room 40, it is filled with catalyzer in tail gas clean-up room 40, one end of tail gas clean-up room 40 is connected with inlet pipe 10, inlet pipe 10 inwall is provided with temperature sensor 11, the other end of tail gas clean-up room 40 is connected with vapor pipe 50, also comprise well heater 30, well heater 30 is cylindrical, well heater 30 is horizontally installed in tail gas clean-up room 40, one end of well heater 30 is stretched out from tail gas clean-up room 40 sidewall, one end that well heater 30 stretches out tail gas clean-up room 40 is connected with controller 20, temperature sensor 11 is connected with controller 20.

In addition, in the present embodiment, tail gas clean-up room 40 is cylindrical. Advantage is, convenient installation on automobile chassis. Inlet pipe 10 and vapor pipe 50 are arranged on the middle part of two bottom surfaces of cylindrical tail gas clean-up room 40. Advantage is, can ensure the uniformly and effectively purification of tail gas in tail gas clean-up room 40. Well heater 30 is at least two. Advantage is, it is to increase the heats of well heater 30. Well heater 30 radial direction in tail gas clean-up room 40 is symmetrical arranged. Advantage is, catalyzer is heated uniformly and effectively.

During automobile starting, well heater 30 starts thereupon and is heated by catalyzer, although vehicle exhaust temperature is lower, but the effect due to well heater 30 so that catalyzer can reach activation temperature, is heated by vehicle exhaust. Unlike the prior art, after automobile normally runs, vehicle exhaust temperature raises, the temperature needed for catalyzed reaction can be reached, now, owing to being provided with temperature sensor 11 at inlet pipe 10 inwall, and one end that well heater 30 stretches out tail gas clean-up room 40 is connected with controller 20, and temperature sensor 11 is connected with controller 20. Temperature sensor 11 is by signal transmission to controller 20, and controller 20 controls well heater 30 and stops heating. So, the present embodiment is energy heatable catalyst when automobile starting, can stop well heater when automobile normally runs, save the energy.

Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and/or characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, it is also possible to make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability that the utility model is implemented. The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification sheets etc. record the content that may be used for explaining claim.
