Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ozone catalytic anti-discharge backwash drainage two-phase separator. Background Technology
[0002] Ozone catalytic oxidation systems require regular backwashing during operation to maintain catalyst activity. However, existing technologies have the following prominent problems: conventional backwash drainage channel designs result in significant catalyst loss during simultaneous gas and water backwashing; backwash drainage carries a large number of precious metal catalyst particles (such as iron, manganese, copper, cobalt, etc.), causing economic losses and secondary pollution; and catalyst blockage and accumulation in pipelines and tanks affect the stable operation of the system.
[0003] Secondly, traditional screen filtration devices are prone to clogging. Initially, they are effective at intercepting backwash catalyst leakage, but after a period of operation, they gradually become clogged and lose their interception function, resulting in increased leakage, making cleaning difficult and frequent, and increasing maintenance costs. Utility Model Content

This solves the problem of material leakage during backwashing drainage in ozone catalytic oxidation systems, improves the stability of ozone catalytic oxidation systems, and reduces operating and maintenance costs.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an ozone catalytic anti-leakage backwash drainage two-phase separator, comprising a main shell, a flow-guiding separation ring plate, and a water collection hopper outlet weir. A conical outer shell is fixedly installed at the bottom of the main shell. An upward-opening straight cylindrical section is provided inside the main shell. A conical bucket section is provided inside the conical outer shell. A grid-shaped support is provided inside the straight cylindrical section. The grid-shaped support is grid-shaped. The water collection hopper outlet weir is located inside the straight cylindrical section. The bottom of the conical bucket section has a downward-opening bottom opening. The water collection hopper outlet weir includes an outlet pipe that passes through the straight cylindrical section, the conical bucket section, and the bottom opening. A flange connection is installed at the lower end of the outlet pipe. The flow-guiding separation ring plate is located inside the straight cylindrical section.
[0008] Furthermore, a water collection bucket is provided at the top of the water outlet pipe to achieve the effect of centralized water delivery.
[0009] Furthermore, a flow guiding cavity is formed inside the flow guiding and separating ring plate, and when the flow guiding and separating ring plate is placed above the water collecting hopper, the water collecting hopper and the water outlet pipe are located inside the flow guiding cavity.
[0010] Furthermore, the bottom of the flow-guiding and separating ring plate is provided with a slot, which can be inserted and connected to the grid bracket.

[0012] Furthermore, four vertically erected support legs are fixedly provided on the outer end face of the conical shell, and the support legs provide stable support.
[0013] (III) Beneficial Effects
[0014] This invention provides an ozone catalytic anti-leaking backwash drainage two-phase separator. It features the following:
[0015] Beneficial effects:
[0016] 1. In this scheme, the backwash water from the simultaneous backwashing of air and water enters the main body shell along the upper edge of the straight section of the main body shell, thereby separating the backwash air from the catalyst particles. The backwash drainage after entering the main body shell is guided and separated from the catalyst particles under the action of gravity and inertia, thus preventing the catalyst from being lost during backwash drainage.
[0017] 2. The design of the main shell of this solution greatly reduces the area of the backwash drainage water collection structure in the ozone catalytic oxidation system. In addition, the central arrangement of the main shell also ensures the uniform and stable flow in the ozone catalytic oxidation system. Attached Figure Description

[0024] This utility model embodiment provides an ozone catalytic anti-leaking backwash drainage two-phase separator, such as... Figure 1-5 As shown, the device includes a main shell 101, a flow-guiding and separating ring plate 105, and a water collection bucket outlet weir 109. A conical shell 107 is fixedly provided at the bottom of the main shell 101. A straight cylindrical section 106 with an upward opening is provided inside the main shell 101. A conical bucket section 108 is provided inside the conical shell 107. A grid support 113 is provided inside the straight cylindrical section 106. The grid support 113 is grid-shaped. The water collection bucket outlet weir 109 is located inside the straight cylindrical section 106. The bottom of the conical bucket section 108 has a bottom opening 115 with a downward opening. The water collection bucket outlet weir 109 includes an outlet pipe 103. The outlet pipe 103 passes through the straight cylindrical section 106, the conical bucket section 108, and the bottom opening 115. A flange connecting plate 104 is installed and connected to the lower end of the outlet pipe 103. The flow-guiding and separating ring plate 105 is located inside the straight cylindrical section 106.
[0025] It should be further noted that the flange connecting plate 104 was connected to the external output pipeline through the flange connection.
[0026] Furthermore, the top of the water outlet pipe 103 is provided with a water collection bucket 112 to achieve the effect of centralized water delivery.
[0027] Furthermore, a flow guiding cavity 111 is formed inside the flow guiding and separating ring plate 105. When the flow guiding and separating ring plate 105 is placed above the water collecting hopper 112, the water collecting hopper 112 and the water outlet pipe 103 are located inside the flow guiding cavity 111.
[0028] It is worth noting that the diameter of the flow-guiding and separating ring plate 105 is smaller than the diameter of the straight cylindrical section 106 inside the main body shell 101.
[0029] Furthermore, the bottom of the flow-guiding and separating ring plate 105 is provided with a slot 110, which can be inserted and connected to the grid bracket 113.
[0030] Furthermore, the bottom of the water collection hopper 112 is fixed with four symmetrically distributed fixing brackets 114, which can be installed above the grid bracket 113.
[0031] Furthermore, four vertically erected support leg base plates 102 are fixedly provided on the outer end face of the conical shell 107, and the support leg base plates 102 play a role in stabilizing support.
[0032] When using this solution, the main body shell 101 is fixed by the bottom support plate 102. The backwash drainage enters the main body shell 101 through the upper edge of the straight section 106. The grid support 113 in the lower middle part of the straight section 106 is used to support and fix the flow guide separation ring plate 105 and the water collection bucket 112. The lower part of the main body shell 101 is a cone-shaped shell 107, which is used to separate and discharge the catalyst particles in the backwash drainage, and fall back into the ozone catalytic reactor from the bottom opening 115 at the bottom of the cone shell 107.
[0033] During backwashing of the ozone catalytic system, the backwash drainage enters the main body shell 101 from the upper edge of the straight section 106 of the main body shell, and descends through the annular cross section between the straight section 106 of the main body shell and the flow separation ring plate 105. Without the backwash air adhering to and entraining the catalyst particles, they fall back into the ozone catalytic reactor along the inner wall of the conical bucket section 108 inside the conical shell 107. The drainage rises along the cross section of the flow separation ring plate 105 to the flow guiding cavity 111, and is collected by the water collection bucket 112 and discharged through the water outlet pipe 103. This greatly reduces the area of the backwash drainage collection structure in the ozone catalytic oxidation system. In addition, the central arrangement of the main body shell also ensures that the flow in the ozone catalytic oxidation system is uniform and stable.
[0034] Meanwhile, the backwash water from the simultaneous backwashing of air and water enters the main body shell 101 along the upper edge of the straight section of the main body shell, thus separating the backwash air from the catalyst particles. The backwash drainage after entering the main body shell 101 is guided and separated from the catalyst particles under the action of gravity and inertia, preventing the catalyst from being lost during backwash drainage.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
