Description

Technical Field

[0001] The utility model relates to the technical field of factory waste gas purification and treatment equipment, in particular to a UV photo-oxidation catalyst for factory waste gas treatment. Background Art

[0002] UV photocatalytic treatment uses high-energy, high-ozone UV light beams to decompose oxygen molecules in the air to produce free oxygen, also known as reactive oxygen. Because free oxygen carries an imbalance of positive and negative electrons, it must combine with oxygen molecules to produce ozone. Ozone has a strong oxidizing effect on organic matter and has an immediate effect on removing industrial waste gas and other irritating odors. Therefore, after industrial waste gas is input into the UV photocatalytic equipment through an exhaust fan, a synergistic decomposition and oxidation reaction is carried out on the industrial waste gas, converting it into low-molecular compounds, water, and carbon dioxide, which are then discharged through the exhaust duct. At the same time, the high-energy UV light beam is used to crack the molecular bonds of bacteria in the industrial waste gas, destroying the bacterial nucleic acid. The ozone oxidation reaction is then carried out to completely purify and kill the bacteria.

[0003] Existing UV photocatalytic converter purification boxes are equipped with filter cotton, UV photocatalytic lamps, catalytic plates, and activated carbon filters, which respectively perform filtration, oxidation, catalysis, and re-filtration. The purification box is directly installed with a door to facilitate internal maintenance and cleaning and replacement of filter elements. However, UV photocatalytic converters are different from ordinary exhaust gas filtration equipment. The ozone and ultraviolet rays generated inside them are harmful to the human body. Most UV photocatalytic converters on the market currently do not take sealing measures between the purification box and the door. Although the exhaust gas emissions are directional through the fan, when the exhaust gas emission speed slows down, there is still a risk of ultraviolet and ozone leakage between the purification box and the door, which needs to be improved. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a UV photocatalyst for factory waste gas treatment, which is used to solve the problem that most UV photocatalysts on the market do not take sealing measures between the purification box and the box door, resulting in the risk of ultraviolet and ozone leakage when the waste gas emission rate slows down.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A UV photocatalytic converter for treating factory waste gas comprises a purification box, an air inlet pipe and an air exhaust pipe arranged at both ends of the purification box, a door opening arranged on the purification box, and a swing door hingedly mounted on the purification box at a position corresponding to the door opening. The purification box is provided with strip grooves at positions above and below the corresponding door opening, and embedded grooves are horizontally arranged in the strip grooves. Sealing strips corresponding to the strip grooves are fixedly connected to the top and bottom of the front of the swing door, and embedded strips corresponding to the embedded grooves are provided on the back of the sealing strips.

[0007] The swing doors are symmetrically arranged and embedded in the door openings. A circle of expansion rubber rings are arranged around the back of the swing doors, which are interference-fitted with the inner wall of the door opening. The expansion rubber rings on the back of the symmetrically arranged swing doors are also interference-fitted with each other.

[0008] A hinge hinged to the purification box is installed on the opposite side of the front of the symmetrically arranged flat door. A folding strip is provided between the opposite sides of the two flat doors and the door opening, and the hinge is located outside the folding strip.

[0009] The front side of one of the symmetrically arranged casement doors facing away from the hinge is provided with an outer cover strip for pressing on the front side of the other casement door facing away from the hinge, and locks are installed between the symmetrically arranged casement doors.

[0010] Preferably, the purification box is seamlessly welded with the air inlet pipe and the air exhaust pipe to form an integrated structure.

[0011] Preferably, the swing door is a vertical rectangular fiberglass molded flat door.

[0012] Preferably, the strip groove is a rectangular groove, and the sealing strip is adapted to the shape and size of the strip groove.

[0013] Preferably, the embedded rubber strip and the sealing rubber strip are an integrated structure, and the embedded rubber strip is in the shape of a round rod, and the shape and size of the embedded rubber strip are adapted to the embedded groove.

[0014] Preferably, the sealing rubber strip, the embedded rubber strip, the expansion rubber ring, the folding rubber strip and the outer cover rubber strip are all EPDM rubber parts that are resistant to strong acids, alkalis and ozone.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model improves the sealing between the swing door and the door opening of the purification box from all sides by means of expansion rubber rings, folding rubber strips, sealing rubber strips and embedded rubber strips, and improves the sealing between the swing door and the swing door by means of expansion rubber rings and outer cover rubber strips, so as to achieve the purpose of enhancing the sealing in all directions at the door opening position between the swing door and the purification box. After the swing door is closed by pressing in the expansion rubber rings, sealing rubber strips and embedded rubber strips, the ultraviolet rays and ozone generated in the purification box can be isolated and prevented from leaking outwards, thereby improving safety, and solving the problem that most UV photocatalytic purification boxes and the box doors on the market have no sealing measures taken between them, resulting in the hidden danger of ultraviolet rays and ozone leakage when the exhaust gas emission speed is slowed down.
