Description

Diesel engine DPF cleaning and regeneration equipment
Technical field
The present invention relates to cleaning device more particularly to a kind of diesel engine DPF cleaning and regeneration equipment.
Background technique
Diesel vehicle has many advantages, such as that fuel consumption rate is low, torque output is high, Power coverage range is wide, in communications and transportation and work It is used widely in the fields such as journey machinery.As adding for automobile emission regulation is tight, diesel vehicle only uses after-treatment device ability Meet the following stringent emission regulation.The discharge of tri- kinds of nuisances of HC, CO, NOx will be few than gasoline car in exhaust gas from diesel vehicle, but It is that soot particulate discharge amount is higher than gasoline car discharge amount in its tail gas, or even is higher by tens times.The solid of diesel emission Pollutant is mainly particulate matter, it is by doing soot (SOOT), soluble organic fraction (SOF), a small amount of sulfuric acid and sulfate Deng composition.With being continuously increased for global diesel vehicle yield, the exhaust emissions problem of diesel vehicle has caused the height of national governments Degree pay attention to, worked out stringent exhaust gas from diesel vehicle emission regulation in succession both at home and abroad, such as European Union respectively at 2005,2008 and Implementation Europe IV in 2013, VI exhaust gas from diesel vehicle discharge standard of Europe V and Europe, have done stringent rule to exhaust gas from diesel vehicle emissions concentration It is fixed.China also comes into effect state four, five exhaust gas from diesel vehicle discharge standard of state in succession.It is usually all using improvement hair both at home and abroad at present Combustion technology combination selective catalytic reduction system operating (SCR) in motivation machine, or combine gas recirculation system (EGR) and diesel vehicle Particulate matter trap (DPF)/big mainstream technology route of particulate matter catalyst converter (POC) exhaust aftertreatment technology two is realized.
DPF can effectively reduce diesel particulate emission, but with the increase of mileage travelled, more and more particle depositions In trap, exhaust back pressure is caused to increase, the economy and dynamic property of engine deteriorate, it is therefore necessary in time by trapping Combustible particle is disposed, and realizes the regeneration of particle trapper.Under the revolving speed and load that diesel engine works normally, delivery temperature one As at 250~500 DEG C, and the burning point of particle is generally 550~600 DEG C, by the exhaust of diesel engine, is difficult to make trap again It is raw.The particulate oxide trapped in DPF is burnt, is now universal dpf regeneration mode, but this mode is it is easier that filtering body Cause thermal damage.And largely because the particle that lube oil additive packet, engine wear metal generate cannot pass through the side of oxidizing fire Formula removal, over time, the accumulation of this some particles block the duct DPF, reduce the micro particle catching ability of DPF, meanwhile, Exhaust pipe back pressure is caused to increase, oil consumption increase, power reduce, and result even in DPF scaling loss and scrap, to cause severe environments dirty The economic loss of dye and replacement DPF.
Summary of the invention
Goal of the invention: in view of the above problems, the present invention proposes a kind of efficient reverse blow formula diesel engine DPF cleaning and regeneration Equipment.
Technical solution: diesel engine DPF cleaning and regeneration equipment of the present invention, including rinse bath, it is built in rinse bath bottom The cleaning trays in portion further include cleaning liquid pipeline, compressed air line, cleaning rod, the rotation for driving cleaning trays to rotate Transmission, cylinder and high pressure nozzle for driving cleaning rod to move back and forth, the high pressure nozzle respectively with the cleaning rod, clear The liquid outlet of washing lotion pipeline is connected with the gas outlet of compressed air line.
Preferably, the liquid outlet of the cleaning liquid pipeline and the gas outlet of compressed air line pass through metal hose and high pressure Nozzle connection.
Preferably, compressed air is hot compressed air, it can be achieved that drying to the rapid purging inside DPF, and the compression is empty Air pipe is stainless steel tube, to prevent heat loss, is wrapped with insulating layer in the pipe of the stainless steel tube.
Preferably, the compressed air hose road is equipped with pressure gauge and pressure-regulating valve.
Preferably, ultrasound shake, heating and temperature sensing system are equipped in order to make cleaning effect more preferably, inside the rinse bath System.Supersonic generator device operating voltage AC220 ± 10V, supersonic generator have over-voltage, overcurrent, and output short-circuit etc. is protected Shield measure;The heating and temperature-sensing system use digital intelligent formula temperature controller.
Preferably, it is equipped with liquid level sensor inside the rinse bath, detects that cleaning solution has on a small quantity by liquid level sensor Cleaning solution can be added after loss, keep the capacity of cleaning solution in rinse bath.
Preferably, the bottom of rinse bath is equipped with drain pipe, is taken away the cleaning solution after by diaphragm pump.
The utility model has the advantages that compared with prior art, diesel engine DPF cleaning and regeneration equipment of the invention inside sets ultrasonic cleaning system System, is aided with heating means, by ultrasonic cleaning, reverse blow formula high pressure washing and hot compressed air purging three stage mistakes of drying Journey carries out cleaning and regeneration to blocking DPF exemplar, reaches the particle supplementary set performance of fast quick-recovery diesel engine DPF, improves engine row Gas back pressure, thus reduce blocking DPF maintenance or replacement cost, reduce diesel engine oil consumption, restore diesel engine engine function Rate and recovery DPF tail gas clean-up ability.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, diesel engine DPF cleaning and regeneration equipment, including rinse bath 1, it is built in the cleaning support of 1 bottom of rinse bath Disk 2, cleaning liquid pipeline, compressed air line 6, cleaning rod 8, the rotation for driving cleaning trays 2 to rotate are driven 3, for driving The cylinder 9 and high pressure nozzle 4 that dynamic cleaning rod 8 moves back and forth, high pressure nozzle 4 go out liquid with cleaning rod 8, cleaning liquid pipeline respectively Mouth is connected with the gas outlet of compressed air line 6;1 bottom of rinse bath is additionally provided with drain line and equipped with valve 18.
Ultrasound shake 5, heating and temperature-sensing system 10 and liquid level sensor 12 are additionally provided in rinse bath 1.In order to guarantee Ultrasound shake 5 is evenly arranged in 1 side wall of rinse bath and bottom, supersonic generator device work electricity by preferable ultrasound effect AC220 ± 10V is pressed, supersonic generator has over-voltage, overcurrent, the safeguard measures such as output short-circuit;Heating and temperature-sensing system Cleaning solution to carry out heating and monitoring temperature to the cleaning solution in rinse bath 1, is heated to set temperature, can be improved clear by 10 Effect is washed, heating and temperature-sensing system 10 use digital intelligent formula temperature controller;Cleaning solution is detected by liquid level sensor 12 Cleaning solution can be added after having a small amount of loss, to keep the capacity of cleaning solution in rinse bath 1.
