Catalytic Layer.
As shown in Figure 1, impurity resettlement section 30 is formed at the bottom surface of the first conveying pipe portion 10, and induction can be housed to described the
The impurity 1 contained in the exhaust gas G1 of one direction and whereabouts.Impurity resettlement section 30 can be the ash bucket of downward concave funnel shaped
(hopper), it can be such that impurity 1 is laminated downwards.
As shown in Figure 1, the first baffle plate 40 by first conveying pipe portion 10 inside projectedly in the form of install, can induce flow into
The exhaust gas G1 of first conveying pipe portion 10 makes the second direction in its airflow direction to the second conveying pipe portion direction drastically change.
As shown in Figure 1, the form that the first baffle plate 40 can be protruded to the inside of the first conveying pipe portion 10 is installed, so that the
The exhaust gas G1 of one conveying pipe portion 10 can be to the second conveying 20 conversion direction of pipe portion by impurity resettlement section 30.Moreover, the first baffling

The discharge of slow impurity 1 and purification efficiency can be reduced, if the first protrusion length B1 is too short, the rotary force of impurity 1 can be reduced, from
And purification efficiency can be reduced.
As shown in figure 3, the second conveying pipe portion 20 may include path heights E, the exhaust gas G1 flowed into the first conveying pipe portion 10
Distance when flowing into and through the first baffle plate 40 can be more than path heights E.For example, the first orientation distance C1 subtracts first
The first of protrusion length B1 can be more than path heights E by distance D1.
That is, the first protrusion length B1 so that the exhaust gas G1 that flows into passes through in the first conveying pipe portion 10 first by distance D1
It is that the form of more than the path heights E formed in the second conveying pipe portion 20 is formed, so as to maximumlly improve purification efficiency.
As shown in figure 4, the waste gas purification apparatus 400 that another embodiment of the present invention is related to may also include the second baffle plate 60,

Without prejudice to the form installation of the discharge of purification gas G2, on the basis of horizontal plane and obliquely to be installed to angle A 2 under second,
So as to maximally improve purification efficiency.For example, when to angle A 2 being certain angle above and below under second, inflow entrance
Broaden and outlet narrows, the pressure differential of inflow entrance and outlet is excessive, can reduce purification efficiency, thus, to angle under second
A2 can be 30 degree to 50 degree.
As shown in fig. 6, the second baffle plate 60 of the waste gas purification apparatus 600 that another embodiment of the present invention is related to can protrude
The form installation of certain distance.For example, the length obliquely protruded to 30 direction of impurity resettlement section of the second baffle plate 60 can be with
It is the second protrusion length B2.Moreover, the virtual point that extends of the second baffle plate 60 on impurity resettlement section 30 can be second
Extend point 42, can be the from the tie point of the second baffle plate 60 and purification gas outlet H to the second distance for extending point 42
Two orientation distance C2.
As shown in fig. 6, the second baffle plate 60, in order to maximize purification efficiency, the second protrusion length B2 can be the second orientation
The more than 33% to 42% of distance C2.For example, if the second protrusion length B2 is long, since inflow entrance and outlet narrow,
The discharge of impurity 1 can be slowed down, purification efficiency can be reduced, if the second protrusion length B2 is too short, the rotary force of impurity 1 diminishes meeting
Reduce purification efficiency.
As shown in fig. 7, the impurity resettlement section 30 for the waste gas purification apparatus 700 that another embodiment of the present invention is related to is to recessed
The ash bucket of sunken funnel shaped, can be formed with induction planar portions 70, its table between the first conveying pipe portion 10 and impurity resettlement section 30

In the table 3, the first inflow entrance is mounted in the inflow entrance on the position away from outlet, and the second inflow entrance is peace
Inflow entrance mounted in adjacent rows outlet port.
As understood shown in the table 3, the average pressure of inflow entrance and the pressure of outlet are from type 6 (1：0.54) to type
11(1：0.27) as baffle plate length shortens and reduces, the pressure differential of inflow entrance and outlet is also from type 6 (1：0.54) extremely
Class1 1 (1：0.27) as baffle plate length shortens, pressure differential also reduces.

As shown in the table 2, by changing the baffle plate length when impurity size is 100 μm, 140 μm, 200 μm,
Removal rate is tested.It follows that when impurity size is 100 μm, in type 6 (1：0.54) when, removal of impurity is most
It is high.
In addition, when impurity size is 200 μm, in type 6 (1：0.54), type 7 (1：0.49), type 8 (1：0.43) and
Type 9 (1：0.38) in, higher removal rate is shown, the shorter Class1 0 (1 of the length of the baffle plate：And type 0.32)
11(1：0.27) in, relatively low removal rate is shown.
Figure 10 is the removal of impurity and pressure differential for the baffle plate length for showing the waste gas purification apparatus 300 based on Fig. 3
The table of comparisons.
Understand as shown in Figure 10, the length of the baffle plate is with from type 6 (1：0.54) to Class1 1 (1：0.27) become
Short, removal rate reduces when the pressure differential (△ P) and impurity size of inflow entrance and outlet are 100 μm, 140 μm and 200 μm.
Thus, if the length of the baffle plate shortens, the pressure differential of the inflow entrance and the flow export reduces, and
And would know that removal rate reduction, therefore, in order to formed the pressure differential of the less inflow entrance and the flow export and maintain compared with
High removal of impurity, the ratio setting relative to the baffle plate length of the orientation distance are 1：When more than 0.38 more
