Embodiment 1
[0036] attached Figure 1-4 The first embodiment of the honeycomb photocatalytic reactor is given. The honeycomb photocatalytic reactor in this embodiment is composed of a rectangular box, an inspection door, a reaction substrate, a lamp tube and its accessories.
[0037] The box body 1 is used to house the honeycomb-shaped photocatalytic reaction module 8. Inside the box body 1, a plurality of baffles 7 are arranged. pass. The exhaust gas enters the box 1 from the air inlet 2, and after being filtered by the primary filter device (such as non-woven fabric) at the air inlet 2, it enters the honeycomb photocatalytic reaction module 8, and is discharged from the exhaust port 4 after purification. The flanges 3 on the air inlet 2 and the exhaust port 4 are used as reserved interfaces for connecting with the pipelines of the exhaust gas collection system and the exhaust gas discharge system respectively.
[0038] The inlet and outlet ends of the above-mentioned reactor are prov...
Embodiment 2
[0042] attached Figure 5 The second embodiment of the honeycomb photocatalytic reactor is given. The honeycomb photocatalytic reactor in this embodiment is composed of a rectangular box, an inspection door, a reaction substrate, a lamp tube and its accessories.
[0043] In this embodiment, the only access door 5 is located on the top of the box body 1, the maximum opening and closing angle of the access door 5 is 180°, and a bead is provided at the connection between the access door 5 and the box body 1 to ensure airtightness. In order to facilitate direct hoisting from the top, the honeycomb photocatalytic reaction modules 8 are connected by welding in this example.
[0044] Other components and their connections are the same as in Embodiment 1.
Embodiment 3
[0046] attached Image 6 The third embodiment of the honeycomb photocatalytic reactor is given. The honeycomb photocatalytic reactor in this embodiment is composed of a box body, an inspection door, a reaction substrate, a lamp tube and its accessories.
[0047] In this embodiment, the box body 1 is a circular tubular structure, and its diameter is the same as that of the air duct for collecting the gas to be treated, and flanges 3 are provided on both the air inlet 2 and the exhaust port 4 . The installation method is to install the reactor directly into the collection pipeline as a piece of air pipe, and connect it to the air pipe through the flange 3 of the air inlet and outlet.
[0048] In this example, only one honeycomb-shaped photocatalytic reaction module 8 is placed in the box, and a plurality of reaction modules can also be arranged, and each reaction module is connected by welding.
[0049] When overhauling, the entire reactor can be overhauled after it is removed...
