First, the first mixing chamber 100 will be described in detail with reference to FIGS. 2 and 3. FIG.

The first mixing chamber 100 is an apparatus for primarily mixing toxic substances to be measured and includes an inlet 110, a mixing unit 120 provided at a rear end of the inlet 110, And an outlet 130.

The inflow section 110 has three toxic material inflow sections 112 formed therein to allow liquid toxic substances, gaseous toxic substances and mist to be introduced, and a sample containing the toxic substances can be mixed A first gas inlet 111 into which a sheath gas flows is formed.

The toxic material inlet 112 is disposed radially around the first gas inlet 111 and the toxic materials introduced into the toxic material inlet 112 are introduced at an angle . 2, the first gas inlet 111 flows along the longitudinal direction of the first mixing chamber 100, while the three toxic gas inlet 112 pass through the first mixing chamber 100, 1 gas inlet 111 at a predetermined angle. This configuration has the effect that the mobile phase gas and the toxic substances can be primarily mixed with the influent flow, because the toxic substance flows into the mobile phase gas at different angles with respect to the flow of the mobile phase gas.

The mixing unit 120 provided at the downstream end of the inlet 110 may include a plurality of pores formed with a plurality of pores so as to perform a function of more completely mixing the mixed gas primarily mixed with the flow of the mobile phase gas and the toxic substances, (Not shown). That is, the primary mixed toxic substance-containing gas collides with the perforated plate 121 having a plurality of pores formed therein while moving in the space of the mixing part 120, and turbulent flow is formed, and this gas flow passes through the toxic substances and the mobile phase gas Helps to blend perfectly.

Here, the sheath gas is not particularly limited as long as it is a gas which does not contain a toxic substance but does not react with the toxic substance.

The mixed gas is discharged through the first mixed gas outlet 131 of the outflow part 130 provided at the rear end of the mixing part 120. The discharged first mixed gas corresponds to a predetermined humidity and temperature range .

Fig. 4 is a perspective view of the first drying chamber, and Fig. 5 is an exploded view of the first drying chamber. As shown in FIGS. 4 and 5, the first drying chamber 200 provided at the rear end of the first mixing chamber 100 controls the humidity of the first mixed gas. The first drying chamber 200 includes a body 200, A pair of cover parts 210 and 230 which are respectively provided with an inlet part 211 and an outlet part 212 through which the drying chamber gas is introduced, a wire mesh 230, and the wire mesh 230 and the body part 200, A moisture regulator (not shown) filled in the interspace may be provided.

The wire mesh 230 is provided with a predetermined space so that the gas mixed in the first mixing chamber 100 can move. Accordingly, the mixed gas in the first mixing chamber 100 is moved to the inner space of the wire mesh 230, and the moisture content of the mixed gas is adjusted by contacting the moisture control agent filled in the outer periphery of the wire mesh 230 .

Here, the moisture control agent to be filled in the first drying chamber 200 is preferably a silica gel which is a commonly used moisture control agent, but it is not particularly limited as long as it is a substance capable of controlling moisture.

On the other hand, toxic substances include not only liquid phase, gas phase but also particulate toxic substances. It is also possible to produce a toxic substance containing such particulate matter in the apparatus for producing an environmental toxic substance of the present invention.

As described above, after the liquid toxic substance, the gas toxic substance, and the mist are introduced into the first mixing chamber 100 and mixed therein, the first drying chamber 200 filled with the moisture control agent is adjusted to contain the predetermined humidity do. However, when the particulate toxic substance is directly introduced into the first mixing chamber 100, the particulate toxic substance can be removed during the passage through the first drying chamber 200, and the toxic gas passing through the first drying chamber 200 The injected particulate matter and the toxic gas passing through the first drying chamber 200 are not mixed properly.

Therefore, the present invention may further include a second mixing chamber 300 for perfect mixing even when the particulate toxic substance is injected. After the particulate toxic material is injected into the toxic gas that has passed through the first drying chamber 200, these materials are introduced into the second mixing chamber 300 so that the particulate toxic material is uniformly dispersed in the toxic gas.

As shown in FIGS. 6 to 8, the second mixing chamber 300 includes a second mixing chamber gas inlet 311 into which a mixed gas of a toxic mixed gas and a particulate toxic substance discharged from the first drying chamber is introduced. A second mixing chamber body 310 having a predetermined space formed therein with a second mixing gas outlet 312 through which the mixed gas flows out; a cover 320 provided on the body 310; And a third support part 330 spaced apart from the floor by a predetermined distance.

Particularly, the first baffle 313, the second baffle 314 and the third baffle 315 are embedded in the space of the body portion 310. The first baffle 313 and the third baffle 315 And the second baffle 314 may be disposed in a space between the first baffle 313 and the third baffle 315. The second baffle 314 may be disposed in the space between the first baffle 313 and the third baffle 315,

8, the second mixing chamber gas inlet 311 is disposed on one side of the body 310 of the second mixing chamber 300, and thus the second mixing chamber gas The gas containing the particulate toxic substance introduced into the inflow portion 311 collides with the first baffle 313 installed closest to the gas inflow portion 311. The first baffle 313 is bent at a predetermined angle so that the speed and direction of the introduced mixed gas are changed. In the course of colliding with the second baffle 314 and the third baffle 315, the particulate toxic substance is toxic Gas is uniformly mixed.

On the other hand, the second mixing chamber 300 has a remarkable effect when introducing the particulate toxic substance, but it is obvious that the second mixing chamber 300 can be used even when the particulate toxic substance is not introduced. That is, when it is necessary to mix the mixed gas passing through the first drying chamber 200 more completely, the mixed gas may flow into the second mixing chamber 300 and mixed. In addition, the humidity of the toxic gas passing through the second mixing chamber 300 may be measured. If the humidity of the toxic gas passes through the second mixing chamber 300, the humidity may be adjusted to flow into the second drying chamber 400.

Here, the second drying chamber 400 is the same as that of the first drying chamber 200, and a detailed description thereof will be omitted.

Further, it is measured whether the temperature of the mixed gas passing through the second drying chamber 400 falls within a predetermined range. If the temperature exceeds the predetermined range, the temperature can be adjusted to a predetermined temperature by flowing into the coil heater.

The apparatus for generating toxic substances of the present invention may further include a temperature measuring sensor, a humidity measuring sensor, and a plurality of gas conveying pipes, and may further include a control unit for receiving the measured values of the sensor and controlling the flow of the gas.
