Description

Exhaust gas treatment system

The present invention relates to a pollutant treatment equipment in an industrial process, in particular to an exhaust gas treatment system.

Referring to FIG. 1, it is an existing exhaust gas treatment device 1 including an inlet washing unit 11 suitable for communicating with front-end manufacturing equipment (not shown), a reaction unit 12 communicating with the inlet washing unit 11, and a reaction with the reaction The outlet washing unit 13 communicated with the unit 12 and a water tank 14 for receiving washing wastewater. The inlet washing unit 11 includes a body 110 defining an inner space 100, a nitrogen gas supply pipe 111 disposed on the body 110 and communicating with the inner space 100, and a nitrogen gas supply pipe 111 spaced apart from the nitrogen gas supply pipe 111 The body 110, and a pressure detection module 112 for detecting the air pressure value of the inner space 100. The nitrogen supply pipe 111 is used to supply nitrogen to the inner space 100. Since the nitrogen is an inert gas for chemical reaction, in addition to being able to adjust the gas concentration in conjunction with the additionally introduced reaction gas, it can also promote without chemical reaction The gas in the inner space 100 flows and provides additional kinetic energy for gas movement, thereby reducing the chance of dust particles in the exhaust gas adhering to the inner wall surface of the body 110.

However, in order to actually detect the gas pressure in the inner space 100, the pressure detection module 112 must necessarily directly sample the gas in the inner space 100, so though the nitrogen supply pipe 111 can reduce the adhesion of dust particles to the gas In the case of the body 110, it is difficult to ensure that the pressure detection module 112 is not affected by the dust particles of the exhaust gas. When the pressure detection module 112 is attached to the dust particles of the exhaust gas, or even blocked by the dust particles, of course, it will affect the accuracy of the pressure detection. For the automatic operation of performing judgment based on the pressure value in the inner space 100 In other words, it will inevitably have adverse effects, and may even affect the safety of the operation of the exhaust gas treatment device 1.

Therefore, the purpose of the present invention is to provide an exhaust gas treatment system that can ensure the normal operation of pressure detection.

Therefore, the novel exhaust gas treatment system includes an inlet washing unit, a reaction unit connected downstream of the inlet washing unit, and an outlet washing unit connected downstream of the reaction unit.

The inlet washing unit includes an inlet body defining a first inner space, and an inlet auxiliary module disposed on the inlet body. The inlet auxiliary module has an inlet shell portion disposed on the inlet body and having a first opening facing the first inner space, and an inlet shell portion disposed on the inlet shell portion and having a communication with the first inner space and A first sampling tube facing the first sampling hole on the same side of the first port, a first air pressure sensor connected to the first sampling tube, and a first gas port connected to the inlet shell and passing through the first port A first nitrogen supply pipe connected to the first inner space.

The effect of the present invention is that the first sampling hole of the first sampling tube is on the same side as the first port of the inlet shell portion, so the first nitrogen supply tube inputs nitrogen in the first inner space, not It will be directly injected into the first sampling hole or the first port directly. In addition to the basic function of avoiding the adhesion of exhaust dust to the inner wall of the inlet body, it can also provide exhaust gas dust away from the first A port and the kinetic energy of the first sampling hole prevent the accumulation of exhaust dust, thereby optimizing the accuracy of the first air pressure sensor detecting the air pressure through the first sampling tube.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same number.

2, a first embodiment of the novel exhaust gas treatment system of the present invention includes an inlet washing unit 2, a reaction unit 3 connected downstream of the inlet washing unit 2, and an outlet washing unit connected downstream of the reaction unit 3 4. It should be explained first that the inlet washing unit 2 and the outlet washing unit 4 mainly treat the exhaust gas by spraying the washing liquid inside, and in the reaction unit 3, the reaction gas is provided for the components of the treated exhaust gas It generates relatively harmless substances through specific chemical reactions, but this part of the exhaust gas treatment process is not the main technical requirement of this new type, so it will not be described in detail later.

Referring also to FIGS. 2 to 4, the inlet washing unit 2 includes an inlet body 21 that defines a first inner space 210 and an inlet auxiliary module 22 disposed on the inlet body 21. The inlet auxiliary module 22 has an inlet housing portion 221 disposed on the inlet body 21 and having a first opening 229 facing the first inner space 210, and an inlet housing portion 221 disposed on the inlet housing portion 221 and having a communication with the The first sampling tube 222 of the first inner space 210 and the first sampling hole 228 facing the same side of the first port 229, a first air pressure sensor 223 connected to the first sampling tube 222, and a connection The first nitrogen supply pipe 224 in the inlet shell portion 221 and communicated with the first inner space 210 through the first port 229.

Wherein, the inlet shell 221 defines an inlet chamber 299 around, and the first nitrogen supply pipe 224 communicates with the inlet chamber 299. That is to say, when the first nitrogen supply pipe 224 supplies nitrogen, it will be directly injected into the first inner space 210 through the first port 229, but will not be reversely injected into the first sampling pipe 222, so it will not affect The first sampling tube 222 samples gas and detects air pressure. In addition, while the first nitrogen supply pipe 224 outputs nitrogen, it can also generate gas kinetic energy away from the first inner space 210 around the first port 229 and even the first sampling hole 228 It is beneficial to keep the exhaust dust away from the first port 229 and the first sampling hole 228, which can naturally prevent the accumulation of dust, and optimize the accuracy of pressure detection while maintaining the smoothness of the first sampling tube 222.

5 to 7, it is a second embodiment of the new exhaust gas treatment system. The difference from the first embodiment is that the outlet washing unit 4 includes an outlet body 41 that defines a second inner space 410, And an outlet auxiliary module 42 disposed on the outlet body 41, the outlet auxiliary module 42 having an outlet shell portion 421 disposed on the outlet body 41 and having a second port 429 facing the second inner space 410 A second sampling tube 422 disposed in the outlet shell 421 and having a second sampling hole 428 connected to the second inner space 410 and facing the same side of the second port 429, and a second sampling tube 422 connected to the second The second air pressure sensor 423 of the sampling tube 422 and a second nitrogen supply tube 424 connected to the outlet shell 421 and connected to the second inner space 410 through the second port 429. Wherein, the outlet shell 421 defines an outlet chamber 499 around, and the second nitrogen supply pipe 424 communicates with the outlet chamber 499.

Although the amount of dust particles will be greatly reduced after the exhaust gas is processed by the reaction unit 3, in order to ensure the normal operation of the second embodiment, the outlet auxiliary unit 42 can also be provided in the outlet washing unit 4, By using the same mode as the inlet auxiliary module 22 of the first embodiment, the second port 429 and the second sampling hole 428 are prevented from accumulating dust, and the accuracy of air pressure detection is ensured. The air pressure value in the second inner space 410 forms another level of assurance. When the outlet washing unit 4 malfunctions, it immediately performs the necessary measures to further improve the overall normal operation of the second embodiment.

In summary, in the novel exhaust gas treatment system, since the first port 229 and the first sampling hole 228 are facing the same side, the nitrogen in the first inner space 210 is input from the first nitrogen supply pipe 224 except It can play the role of preventing exhaust dust from adhering to the inner wall of the inlet body 21, and can also provide kinetic energy to keep the exhaust dust away from the first port 229 and the first sampling hole 228, effectively preventing the accumulation of exhaust dust, thereby optimizing The first air pressure sensor 223 detects the accuracy of the air pressure, so it can really achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
