Specific embodiment
Refering to Fig. 1, Fig. 2, a kind of exhaust collection case of detection vehicle exhaust pm2.5 content, this exhaust collection case includes interior
Case 16, outer container 17, air inlet pipe 1, exhaustor 6, temperature sensor, humidity sensor, pm2.5 detector and vehicle-mounted inverter.
Refering to Fig. 1, Fig. 2, Fig. 4, described interior case 16 is cuboid, and using aluminum alloy material, heats are preferable, significantly
Improve accuracy of detection.Described interior case 16 includes internal box and interior case lid；Described interior case lid passes through bolt 11 and internal box
Connect；Rectangular first heating plate 2 is posted above described interior case lid；Rectangle is posted in front outside described internal box
The second heating plate 10；Rectangular 3rd heating plate 3 is posted at the back side outside described internal box；Due to big in exhaust emissions
The steam coagulation of amount can lead to the humidity in exhaust collection case to increase and affect the accuracy of test data, and therefore here is collected
Case equipped with the heating plate of better performances, this heating plate temperature-controllable, adjustable, the efficiency of heating surface is higher.Can be by temperature control in automobile
In the temperature range of exhaust temperature, greatly reduce the impact for pm2.5 Concentration Testing for the humidity.Described internal box
Front and back is reserved with first and second probe inlet port 8,5 respectively；First and second described probe inlet port 8,5 all has probe sealing
Circle 15；The described interior hole having to casing arranged on left and right sides for inserting air inlet pipe 1, exhaustor 6.
Refering to Fig. 1, Fig. 2, described air inlet pipe 1, exhaustor 6 are cylinder；Described air inlet pipe 1 and exhaustor 6 are equal
It is connected with interior case 16.Described air inlet pipe 1 one end is connected with automobile exhaust pipe by plastic tube, and the other end puts in through outer container 17
In interior case 16；Described exhaustor 6 one end is arranged in interior case 16, and the other end passes through interior case 16 and outer container 17 to be arranged on air
In；Described air inlet pipe 1 is sealed with sealing strip after being connected with plastic tube.Plastic tube select specific specification, high temperature resistant but
It is difficult oversize, enough from automobile exhaust pipe to automobile trunk.The setting of this device exhaustor 6, preferably simulates tail
Environment in automobile exhaust pipe for the gas, reduces because the prolongation of time is so that the increase of pm2.5 content and the experiment number that causes
According to inaccuracy.
Refering to Fig. 1, Fig. 2, described outer container 17 adopts glass material, is rectangle, including its uncovered of outer box body；Described
The arranged on left and right sides of outer box body have the hole for inserting air inlet pipe 1, exhaustor 6 respectively；Described outer box body just, the back of the body
It is provided with first and second placement table 4,9 between the centre position in face and interior box body；First and second described placement table 4,9 adopts glass
Glass material, is cuboid, and its length puts down temperature sensor, humidity sensor and pm2.5 detector enough；Described first is put
Put and inside platform 4, be placed with temperature sensor, humidity sensor, pm2.5 detector；It is placed with inside the second described placement table 9
Temperature sensor, humidity sensor, pm2.5 detector；The setting of first and second placement table 4,9 makes temperature sensor, humidity sensor
Device and pm2.5 detector obtain that location arrangements are more reasonable, improve the reliability of detection data.And due to temperature sensor and
, not in interior case 16, therefore tail gas humidity is less for the impact of temperature sensor and pm2.5 detector, carries for pm2.5 detector
The high accuracy of testing result.Because outer container employs glass material, advantageously in the reading of record detector.Described
The front of outer box body is provided with electric line outlets 7；The length of the described power line of first, second and third heating plate 2,10,3 is enough
It is connected with the inverter outside outer container 17 by the electric line outlets 7 of outer container front lower right-hand corner.
Refering to Fig. 1, Fig. 2, described bolt 11 has four, is separately mounted on four corners of interior case lid, for sealing
Interior case.If blow-by, tail gas can be led to be directly discharged in air, reduce certainty of measurement.And temperature sensor and humidity
Sensor and pm2.5 detector are respectively positioned on outside interior case, do not have the volume of gas in case in taking, thus in addition to exhaustor this
The seal of collecting box is preferable.
Refering to Fig. 3, temperature sensor in the first described placement table 4, humidity sensor, pm2.5 detector first,
2nd, three probes 12,13,14 are entered inside interior case 16 by the first probe inlet port 5；Temperature in the second described placement table 9
Sensor, humidity sensor, first, second and third probe 12,13,14 of pm2.5 detector are entered by the second probe inlet port 8
Inside interior case 16；Described first, second and third probe 12,13,14 is entangled on carefully directly strong with fine rule respectively, makes first, second and third
Probe 12,13,14 is in the middle part of interior box body.First, second and third described probe 12,13,14 structures are identical.
The operation principle of the present invention is: staff carries out needing ready work during Tail gas measuring, first by two temperature
Degree sensor, two humidity sensors, two pm2.5 detectors are individually positioned on the placement table of outer container, by temperature sensor
Probe, humidity sensor probe and pm2.5 detection instrument probe are entangled on carefully directly strong with fine rule respectively, are just passing through interior case respectively
The probe inlet port of the special setting in face and the back side enters, and two group probes are approximately in the middle part of interior case, with two groups of devices
It is to carry out correction data.Before detection, should first the circuit of 3 heating plates be put in order, the electric line outlets being provided with from outer container
Place is drawn and is connected with inverter, then inverter is connected with vehicle-mounted cigarette lighter, carries out pre-add heat treatment.When temperature reaches setting temperature
When spending, automatically keep constant temperature.With the plastic tube of a specific standard, one end of plastic tube is connected with automobile exhaust cylinder, and with sealing
Bar is sealed, and the other end of plastic tube is connected with air inlet pipe, is also sealed with sealing strip.This plastic tube is high temperature resistant but should not be too
Long, enough from automobile exhaust cylinder to automobile trunk.Because vapor afterwards can after entering plastic tube to the cold in vehicle exhaust
Condense into water droplet and experimental result is caused with larger error, but if the vapor in tail gas is all removed then with tail gas in vapour
In-car state is different and to again result in testing result error larger.Ensure the temperature in automotive interior for the tail gas herein for preferable
Humidity environment using rubber-heating piece be wrapped in the outside of plastic tube by temperature adjusting to tail gas the temperature in aiutage, pre-add
Tail gas is made to enter into collecting box after heat.Vehicle exhaust in exhaust collection case is detected by pm2.5 detector, and pm2.5 examines
Survey instrument to be connected with computer by usb line, can real time record experimental data.Tail gas from air inlet pipe enter in case through various probes
Discharge from exhaustor afterwards.Before experiment starts, in record exhaust collection case, the concentration of the initial temperature, humidity and pm2.5 of environment, real
When testing, instruction carriage boot is opened, exhaust collection case be placed in boot by above-mentioned plastic tube connect automobile exhaust cylinder and
Collecting box air inlet pipe, to instruction carriage, under different speeds, the concentration of emission of tail gas pm2.5 detects.Last repairing experiment car exists
Under different speeds, the data of traveling on identical experiment road, draw the detection knot of pm2.5 in vehicle exhaust under different speeds
Really.
This collection box structure is simple, be easily achieved, and can measure the pm2.5 in vehicle exhaust under different speeds.
