Ternary catalyzing unit, is mounted in most important outer purifier in automobile exhaust system, and it can be by vehicle exhaust
The harmful gass such as CO, HC and the NOx discharging are changed into harmless carbon dioxide, water and nitrogen by oxidation and reduction.When
When the vehicle exhaust of high temperature passes through purifier, the catalyst in ternary catalyzing unit will strengthen the work of tri- kinds of gases of CO, HC and NOx
Property, promote it to carry out certain oxidation-reduction chemical reaction, wherein CO is oxidized into colourless, nontoxic titanium dioxide at high temperature
Carbon gas；HC compound is oxidized to water (H20) and carbon dioxide at high temperature；NOx is reduced into nitrogen and oxygen.Three kinds of harmful gas
Body becomes innocuous gas, so that vehicle exhaust is purified.
Ternary catalyzing unit includes housing, and enclosure interior is provided with carrier and liner, and carrier is provided with honeycomb arrangement
Hole, for carrying catalyst, liner is coated on carrier.The housing of existing ternary catalyzing unit is holistic tubular, therefore
After liner, carrier or catalyst attrition lost efficacy, whole ternary catalyzing unit must be scrapped and change, use cost is high.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of carrier that is conveniently replaceable
Ternary catalyzing unit, can reduce the use cost of ternary catalyzing unit.
Technical problem to be solved in the utility model employs the following technical solutions to realize：A kind of carrier of being conveniently replaceable
Ternary catalyzing unit, including housing, liner and carrier, described liner and carrier are arranged in housing, and liner is located at housing and carrier
Between, described housing be respectively arranged at the two ends with oxidation sensors, described housing includes upper shell and lower house, described upper shell
It is semi-circular shape with the radial section of lower house, upper shell and lower house are connected by rapid latch, described rapid latch bag
Include hook, eccentric and retaining ring, described hook is installed in the both sides of upper shell, described eccentric is articulated in the two of lower house
Side, eccentric is provided with handle, described retaining ring and eccentric pivot joint, and retaining ring is mated with hook.Rapid latch make use of partially
Diameter change when it pivots for the heart wheel realizes quick locking and unblock.When car running computer is monitored by oxidation sensors
When needing to change carrier, pulling handle, release locking, raise upper shell and carrier is changed.Then by upper shell and lower casing
Body fastens, and retaining ring is ridden on hook, pulling handle, and retaining ring holds hook makes upper shell and lower house fasten closely, partially
Heart wheel and lower house jam-packed locking.
The technical solution of the utility model also has：The outside bending in end of described handle.Using the technical program, it is easy to handss
Refer to inside incision handle, with pulling handle, make eccentric release locking.
The technical solution of the utility model also has：The inwall of described housing is provided with two annular positioning grooves, and each annular is fixed
In the groove of position, a liner and a carrier are installed, between two annular positioning grooves, there is gap.If enclosure interior is provided only with
One carrier, when needing after carrier depletion that it is integrally changed, using the technical program, can to two carriers respectively more
Change, with cost-effective, two carriers pass through annular positioning groove and are spaced apart, and are blocked with preventing the honeycomb hole on two carriers from misplacing.
The technical solution of the utility model also has：Close up in the two ends of described housing.
The technical solution of the utility model also has：Described oxidation sensors are located at the two ends of upper shell.
The technical solution of the utility model also has：Every side of described housing is provided with two sets of rapid latchs.
With respect to prior art, the beneficial effects of the utility model are：Easily and efficiently housing can be opened and detain
Close, thus changing to carrier or liner, to reduce the use cost of ternary catalyzing unit.
