Abstract
A soot particulate purifying device of a diesel engine comprises a soot heat pipe adhesion box and an automatic temperature-control heat-storage reactor. The soot heat pipe adhesion box consists of a soot heat pipe adhesion box body, a soot heat pipe adhesion box upper cover, a radiating heat pipe, adhesion oil, an inertial force purifying baffle plate and the like, and automatic temperature-control heat-storage reactor consists of an automatic temperature-control heat-storage reactor metal outer sleeve, a heat-storage reaction ceramic inner sleeve, an electric heating plug, a temperature sensor, an automatic heat reaction temperature controller and the like. After tail gas is comprehensively treated by three technical measures including particulate adhesion via the adhesion oil, radiating to the adhesion oil by the aid of the radiating heat pipe, and automatic temperature-control heat-storage reaction, soot particulates in the tail gas are purified, and a purification effect achieves 95% to 100%. The soot particulate purifying device adopts novel external purification technology.
Description
One, technical field:
Diesel engine carbon black particle purifying device is a kind of novel external purification technology that is used to administer diesel engine vent gas carbon soot particles pollutant.
Two, background technique
1, up till now the measure of diesel engine vent gas carbon soot particles pollutant control external purification, use catchers such as integrated type ceramic honeycomb catcher, wire gaze catcher, braided fiber catcher, ceramic fiber, foamed ceramics are arranged.The catcher of above-mentioned these several kinds of different structures all exists a common technology shortcoming, is exactly after catcher is installed in the vent systems exhaust back pressure of motor is improved, and power descends.The particulate matter that deposits on the catcher material is many more, and exhaust back pressure is high more.Therefore must regularly remove particulate on the cake filtration material, remove and be deposited on that the particulate process is a trap regeneration on the filtering material.When the motor proper functioning, the delivery temperature of motor is 200 ℃~500 ℃, and the burning-point of particulate is generally 500 ℃~600 ℃, relies on engine exhaust to be difficult to make trap regeneration.Make trap regeneration just must reduce the burning-point or the raising delivery temperature of particulate.Its method first is on the catcher material, to be coated with palladium platinum-rhodium catalyst coating, can reduce the burning-point of particulate.The secondth, adopt electric heating afterburning and other a kind of method of using the burner heating afterburning of oil inflame.When the gas temperature of catcher surpassed 650 ℃, the core temperature of catcher will surpass the tolerance limit of material.The melting loss be full of cracks will take place in catcher, causes catcher can not reach the catcher purifying effect of expection.(cited paper: publishing house of Beijing Institute of Technology publishes, and Du Zhiyuan separates and builds the 153rd~160 page of light volume front page " engine exhaust and purification " in July, 2007).
2, can again with bigger film-cooled heat quantity of heat given up, can import heat with the heating area of bigger input again with less heating area input heat according to heat pipe; With exchanged heat current density physical property with less film-cooled heat quantity of heat given up; (cited paper: Chemical Industry Press publishes, Zhuan Jun, Zhang Hongzhu " heat-pipe technology and practical applications " 2006 the 1st edition the 10th page), the soot heat pipe that is used for dispelling the heat adheres to the adhesion oil oil temperature in the case; Just can reach the radiating effect that gets twice the result with half the effort
The purifying property of diesel engine carbon black particle purifying device of the present invention; Above-mentioned several kinds of particle trappers have been eradicated fully; Install and use in the process; What the engine back pressure that exists improved, power descends and the trap regeneration process occurs, the be full of cracks of catcher melting loss can not reach the technology shortcoming that expection captures purifying effect.
Three, summary of the invention
Diesel engine carbon black particle purifying device is to adhere to case by the soot heat pipe, and temperature automatically controlled accumulation of heat reactor two-part constitute, and its technological scheme is:
Motor exhaust enters into the soot heat pipe and adheres in the case, purified plate washer by inertial force and stop when turning back for several times up and down, because inertial force effect soot particulate is sticked in the fluid by the oil film that the adhesion oil in the case splashes.Too high in order to prevent to adhere to oil oil temperature, several heat radiation heat pipes are installed in adhering to fluid, just can effectively control too high that the oily temperature of the adhesion of being heated by exhaust heat-energy can not rise, in the hope of guaranteeing to adhere to stable adhesion of physical property of oil.Adhesion process just can be sticked to soot particulate major part in the tail gas in the fluid, and residue is not adhered to soot particulate on a small quantity, enters into temperature automatically controlled accumulation of heat reactor and is oxidized to carbon dioxide.
Beneficial effect
Adopt technique scheme, just can soot particulate in the tail gas be purified, purifying effect reaches 95~100%.This effectively administers strengthening air environmental pollution, ensure people healthy be favourable.
