Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ozone tail gas destroyers, and in particular relates to a drainage device for an ozone tail gas destroyer. Background Art
[0002] Pre-ozone process: In the pre-ozone process, ozone needs to be added to the raw water after it passes through the ozone contact tank. After the ozone is added, some ozone is not fully dissolved (or due to the large amount of ozone added), which will produce some undissolved ozone tail gas. Direct discharge of ozone tail gas will cause great harm to the air, so the ozone tail gas needs to be centrally treated to reduce ozone to oxygen.
[0003] The principle of the ozone tail gas destructor is to suck the tail gas into the reactor through a fan (the installation of this fan can minimize the leakage of ozone because it can ensure that the pipeline system is in a vacuum state). Ozone is decomposed in contact with the catalyst in the reactor. The catalyst is granular between two screens. Since the catalyst is very sensitive to moisture, the cold and humid tail gas is heated to the working temperature by the heating tube at the bottom of the reactor after entering the reactor. The tail gas destructor should always be in operation, even if the ozone production is stopped. This measure is to avoid the formation of condensed water in the catalyst bed when the ozone production stops. Unless the reactor is always in standby mode.
[0004] Considering the stability of the production equipment, the ozone exhaust destructor equipment uses one in use and one in standby. The PLC calculates the running time and switches to start the operation at a fixed time. As a result, one of the equipment is always in a stopped state. Over time, the condensed water of the catalytic bed accumulates in large quantities at the bottom of the reactor, causing great damage to the heating tube. Based on the above problems, it is of great practical significance to design an ozone exhaust destructor drainage device that can timely remove the accumulated water inside the reactor while ensuring the normal operation of the equipment and ensure the safe operation of the equipment.

DETAILED DESCRIPTION
[0043] First of all, it should be noted that the specific structure, features and advantages of the present invention will be specifically described below by way of example, but all descriptions are only for illustration and should not be understood as limiting the present invention in any way.

In addition, in order to simplify the drawings, the same or similar technical features may be marked only in one place in the same drawing.
[0044] In the present utility model, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", "fixation", "screwing" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The present utility model is described in detail below in conjunction with the accompanying drawings. Example
[0045] An ozone exhaust destroyer drainage device comprises a destroyer housing 1 and an air inlet pipe 2 and an air outlet pipe 3 with a fan. The central position of the bottom of the destroyer housing 1 is convex to form a mounting boss 5 for mounting a heating pipe 4. The bottom of the destroyer housing 1 is concave along its outer edge to form a drainage groove 6. The destroyer housing 1 is also provided with:
[0046] A drainage structure, comprising a drainage pipe 7 and a drainage valve arranged on the drainage pipe 7, wherein the drainage pipe 7 is connected to the drainage groove 6;
[0047] The catalytic bed structure is installed inside the disruptor housing 1 through a water guide ring 8, and includes at least two layers of cover bodies 9 assembled into one body, the cover bodies 9 are covered with a screen layer, and storage spaces for storing catalysts are provided between adjacent cover bodies 9.
[0048] In this embodiment, Figure 1-6As shown, this technical solution improves the shape of the bottom of the ozone exhaust destroyer (reactor), changes the original flat bottom of the destroyer shell into a bottom with drainage grooves around it, and installs the heating pipe on the raised mounting boss in the middle. When there is condensed water in the ozone exhaust destroyer, the condensed water will gather in the drainage groove, and the raised heating pipe will not be affected. Then open a DN16 small hole at the drainage groove at the bottom of the reactor of the ozone exhaust destroyer, cut a DN16 316 stainless steel pipe as a drain pipe, thread one end, and weld the other end to the DN16 small hole with argon arc welding, and then install a stainless steel inspection ball valve and a micro electric drain valve on the threaded end. Among them: the stainless steel inspection ball valve remains in the open state, and the switch of the micro electric drain valve is controlled by the actual operating state of the ozone exhaust destroyer. When the ozone exhaust destructor stops running, the micro electric drain valve automatically opens and closes under the control of the time relay; when the ozone exhaust destructor is running, the micro electric drain valve will not be controlled. When the ozone exhaust destructor is running, the exhaust gas is sucked into the destroyer shell through the fan and the air intake pipe. During the flow of the exhaust gas from bottom to top, it will first be heated to the working temperature by the heating tube at the bottom of the reactor and then pass through the catalytic bed structure. The catalytic bed structure includes at least two layers of cover bodies 9 assembled in one body, and the cover body 9 is covered with a mesh layer. A storage space for storing granular catalysts is provided between adjacent cover bodies 9. After passing through the mesh layer on the cover body, ozone will react with the catalyst The ozone is decomposed by contact with the agent to reduce the ozone to oxygen, and when the ozone production stops, condensed water will be formed in the catalyst bed structure. Most of the condensed water will flow along the contour of the catalyst bed structure to the water guide ring platform and under the guidance of the water guide ring platform, flow down along the inner wall of the destroyer shell and finally gather in the drainage groove. Some of the condensed water falls to the bottom of the destroyer shell and will eventually gather in the drainage groove under the action of the bottom shape of the destroyer shell. This embodiment solves the problem of water accumulation in the reactor by improving the bottom shape of the ozone exhaust destructor and increasing the drainage structure of the ozone exhaust destructor reactor, reduces the frequent damage of the heating tube, and improves the safe operation state of the equipment.
[0049] Furthermore, it can also be considered in this embodiment that the drain pipe 7 is a stainless steel pipe vertically arranged at the lower end of the drain groove 6 of the destroyer housing 1, and the drain valve includes a manual stainless steel valve 10 and an electric valve 11. The working process is: the drain electric valve of the ozone exhaust destroyer is controlled to open and close by the operation signal of the system fan, and the signal controlling the drain electric valve is connected to the normally closed contact of the fan main contactor 4K4. When the ozone exhaust destroyer stops working, the fan main contactor 4K4 is disconnected, the normally closed contact is connected, and the time relay KT1 delays to connect KM1, and the KM1 suction contact connects the electric valve opening signal to realize the function of automatic drainage. After the drainage time is reached, KT2 delays to connect KM2, and the KM2 suction contact connects the electric valve closing signal, and disconnects KM1 at the same time, and the drain electric valve automatically closes. It should be noted that: since the connection relationship and circuit structure between the drain electric valve, the fan main contactor, and the time relay are all prior art, they are not elaborated in detail.
[0050] Furthermore, in the present embodiment, it can also be considered that the cover body 9 is a hollow truncated cone frame structure, the heating tube 4 is located below the catalyst bed structure and the heating tube 4 partially extends into the space surrounded by the catalyst bed structure. Since the cover body 9 is a hollow truncated cone frame structure, the overall shape of the catalyst bed structure is a hollow truncated cone. Compared with the catalyst bed in the prior art (the catalyst is stored between two flat screens), the catalyst bed structure in the present embodiment can not only increase the storage area of the catalyst, but also facilitate the condensate to flow along the truncated cone contour of the catalyst bed structure to the water guide ring and flow down along the inner wall of the disruptor shell under the guidance of the water guide ring and finally converge into the drainage groove.
[0051] Furthermore, in this embodiment, it can also be considered that the bottom of the cover body 9 located at the lowest end extends outward to form a circle of supporting outer edge 12, and each cover body 9 is fixed to each other by a combination of bolts and nuts and is placed on the water guide ring platform 8 as a whole through the supporting outer edge 12.
[0052] Furthermore, in this embodiment, it can also be considered that the longitudinal section of the water guide ring 8 is triangular, and the water guide ring 8 has two upper and lower inclined water guide surfaces. Under the guidance of the two water guide surfaces, condensed water can flow down along the inner wall of the breaker shell and finally converge into the drainage groove.
[0053] Furthermore, in this embodiment, it can also be considered that the side wall of the support outer edge 12 is adapted to the shape of the upper water guide surface of the water guide ring platform 8, and a plurality of water guide holes 13 are formed on the outer edge of the upper end surface of the support outer edge 12. The condensation water flowing onto the support outer edge can flow down through the water guide holes and the gap between the support outer edge and the water guide surface.
[0054] Furthermore, in this embodiment, it can also be considered that the air outlet pipe 3 is arranged at the top of the destroyer housing 1, and the air inlet pipe 2 is arranged at the bottom of the side wall of the destroyer housing 1 along the center line of the destroyer housing 1. Example
[0055] Embodiment 2 of the present invention is further improved on the basis of embodiment 1 so as to give full play to the technical advantages of the present invention, which is described below by way of example.
[0056] For example: Figure 7-18 As shown, an ozone exhaust destructor drainage device further includes a preliminary catalytic structure, which is installed inside the destructor housing 1 through a supporting ring 14 and is located below the catalytic bed structure.
[0057] Furthermore, in this embodiment, it can also be considered that the preliminary catalytic structure includes a supporting ring body 15 and a plurality of catalytic plates 6, each of the catalytic plates 16 is fixed to the upper end of the supporting ring body 15 and is distributed in a circular array around the central axis of the supporting ring body 15, and the heating tube 4 is located below the preliminary catalytic structure and a portion of the heating tube 4 extends into the space surrounded by each catalytic plate 16.
[0058] Furthermore, in this embodiment, it can also be considered that a storage cavity for storing catalyst is formed in the catalyst plate 16, and a grid hole 17 communicating with the storage cavity is formed through the catalyst plate 16.
[0059] Furthermore, in this embodiment, it can also be considered that each of the catalyst plates 16 is curved in the same direction, and a guide channel for the exhaust gas to flow from the outer edge to the middle of the catalyst plate 16 is formed between two adjacent catalyst plates 16 .
[0060] Furthermore, in this embodiment, it can also be considered that the air inlet pipe 2 is tangentially arranged at the bottom of the side wall of the breaker housing 1 along the circumference of the breaker housing 1 , or is arranged at the bottom of the side wall of the breaker housing 1 along the center line of the breaker housing 1 .
[0061] In this embodiment, Figure 7-18As shown, taking the present embodiment as an example, the air inlet pipe 2 is tangently arranged along the circumference of the destroyer housing 1 at the bottom of the side wall of the destroyer housing 1. After the exhaust gas is introduced into the destroyer housing through the fan and the air inlet pipe, a vortex will be generated first, that is, it enters the preliminary catalytic structure along the tangent direction of the preliminary catalytic structure. When passing through the catalytic plate, it will contact the granular catalyst in the storage cavity through the grid holes to obtain preliminary decomposition. When passing through the preliminary catalytic structure, since the catalytic plates are bent in the same direction, the exhaust gas can gradually flow to the middle of the preliminary catalytic structure. In this process, the exhaust gas will be heated to the working temperature by the heating tube and then pass through the catalytic bed structure for secondary decomposition. After two decompositions by the primary catalytic structure and the catalytic bed structure, the ozone in the exhaust gas can be further helped to be more fully decomposed.
[0062] It should be noted that the specific structure, connection relationship, working principle, and circuit structure of the PLC, electric valve, fan, relay, etc. used in the utility model are all existing technologies and are not the innovation of this technical solution, so they will not be elaborated in detail.
[0063] The above embodiments describe the present invention in detail, but the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of application of the present invention shall still fall within the scope of the patent coverage of the present invention.
