Abstract
The utility model belongs to the technical field of pipes, and discloses a low-temperature urea water spray pipe for a car purification device meeting the national emission standard IV. The low-temperature urea water spray pipe is mainly technically characterized by comprising a pipe body, wherein quick-change couplers are arranged at two ends of the pipe body, a urea-resistant nylon inner pipe is arranged in the inner layer of the pipe body, a conductor and a semiconductor heating layer are wound on the outer wall of the urea-resistant nylon inner pipe, the conductor is connected with a power supply plug connector, an insulating protection layer and a corrugated pipe jacket are arranged on the outer wall of the semiconductor heating layer, and a temperature control device is arranged on the power supply plug connector. According to the low-temperature urea water spray pipe for the car purification device meeting the national emission standard IV provided by the utility model, when a diesel car drives in a cold region, the power supply plug connector is connected with a power supply, the conductor is electrified to warm the semiconductor heating layer so as to supply heat to the urea-resistant nylon inner pipe, so that the urea water solution of the urea-resistant nylon inner pipe is delivered in a warm environment and can be prevented from being condensed due to coldness, thereby ensuring the usage effect and realizing the energy conservation and environment protection. The temperature control device is arranged on the power supply plug connector to preset a certain temperature, so that the low-temperature urea water spray pipe for the car purification device meeting the national emission standard IV can be used at certain constant temperature.
Description
Technical field
The utility model belongs to the pipe technology field, relates in particular to a kind of state IV automobile purifying apparatus urea water low temperature jet pipe.
Background technique
The hydrocarbon that discharges in the diesel automobile exhaust, the relative gasoline automobile much less of carbon monoxide, but the oxynitrides of discharging and particulate matter are a large amount of and deposit.In order to satisfy state's IV, Europe IV and above emission request, diesel engine is depended merely on the emission controls by improving combustion technology such as combustion modifications and has been difficult to satisfy more and more stricter Abgasgesetz, tail gas must be up to standard by the outer exhaust aftertreatment devices ability of diesel engine, and selective catalytic reduction device is to realize state's IV, Europe IV and above emission request the most efficiently approach and necessary means.Adopt the discharging that the motor of selective catalytic reduction technology can more effective reduction oxynitrides, and have obvious energy-saving effect.Selective catalytic reduction device refers to be installed in the diesel engine automobile air exhausting system, and the oxynitrides of diesel emission is reduced into the catalytic reduction device of nitrogen and oxygen, selects aqueous solution of urea as reducing agent.Aqueous solution of urea is ejected in the outlet pipe of catalyzer countercurrent direction, and gasification is decomposed into carbon dioxide and ammoniacal liquor under the effect of exhaust gas temperature and air-flow, and ammoniacal liquor is reduced into free of contamination nitrogen G﹠W as reducing agent with oxynitrides.The pipeline of the transport urea aqueous solution is more elongated, if can not take effective Insulation, solidifies easily at the regional aqueous solution of urea of cold, and impact is used.
