[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, such directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0029] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present utility model, such descriptions of "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0030] In this patent, the term "comprise", "include" or any other variant thereof is intended to cover a non - exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "comprising..." do not preclude the presence of additional identical elements in the process, method, article or device comprising the said elements.

[0031] By Figures 1-3It can be seen that the embodiment of the present utility model provides a deodorizing device for use in conjunction with a vacuum sewage discharge unit, including a fixed support 4 for supporting the deodorizing device, an exhaust gas collection unit 1 provided on the fixed support 4, a filtration and purification unit 2 provided on the upper layer of the exhaust gas collection unit 1, an observation and monitoring unit 3 provided on the side wall of the deodorizing device, a condensate discharge port 5 provided at the bottom of the exhaust gas collection unit 1, a gas discharge port 6 provided at the top of the filtration and purification unit 2, and a lifting ring 7 provided around the gas discharge port 6. The fixed support 4 is used to fix the deodorizing device to prevent it from moving during use. The fixed support is fixed to the ground by expansion bolts. The expansion bolts are inserted after pre-drilling holes in the ground. When the nut is tightened, the expansion tube inside the bolt will expand outwards and tightly fit on the hole wall, forming a strong frictional force, so as to ensure that the fixed support 4 will not shift during use or when subjected to large external forces. The three feet of the fixed support 4 are equidistantly arranged on the outer periphery, dispersing the pressure of the deodorizing device on the ground and avoiding ground damage caused by excessive single-point stress. One side of the exhaust gas collection unit 1 is connected to the vacuum sewage discharge unit, which is used to collect the exhaust gas generated by the operation of the vacuum sewage discharge unit and adsorb the condensate water in the exhaust gas, storing the condensate water at the bottom of the exhaust gas collection unit. A condensate discharge port 5 is provided at the bottom. When the condensate water is stored to a certain capacity, the condensate discharge port 5 will automatically discharge, effectively ensuring that the filter medium does not adhere inside. The filtration and purification unit 2 is filled with filter medium inside, and removes harmful substances and odors in the exhaust gas through adsorption and chemical reactions. The filter medium is activated carbon. The observation unit 3 is used to observe and monitor the situation inside the deodorizing device, and can monitor the saturation degree of the filter medium in real time. Once it is detected that the filter medium reaches the saturation critical point, the device will automatically trigger the alarm system to remind the operator to replace the medium in an intuitive and efficient manner, so as to ensure the continuity and stability of the deodorizing effect.

[0032] The exhaust gas collection unit 1 includes an exhaust gas collection interface 12 provided on one side of the exhaust gas collection unit 1 and a support member 11. The support member is provided at the center of the exhaust gas collection unit 1 and is used to support the medium support grid 21 of the filtration and purification unit 2. The exhaust gas collection interface 12 connects the vacuum sewage discharge unit and the deodorizing device. During use, the exhaust gas generated by the vacuum sewage discharge unit enters the exhaust gas collection unit 1 of the deodorizing device through the exhaust gas collection interface 12, so as to carry out deodorization.

[0033] The filtering and purification unit 2 is provided with a filtering medium and a medium support grid 21 for placing the filtering medium. The medium support grid 21 is a hollow grid-like structure, which not only prevents the filtering medium from directly falling into the waste gas collection unit 1 and coming into direct contact with the condensed water, avoiding the reduction of the deodorization effect and service life, but also ensures the smooth passage of the air flow, improving the overall purification efficiency. The filtering medium is stacked on the medium support grid 21. When the waste gas enters the deodorization device and passes through the filtering and purification unit 2, the porous structure of the filtering medium can also play a certain physical interception role to prevent the diffusion of odor molecules. Through this adsorption and reaction process, the filtering medium effectively reduces the concentration of odor substances in the air, thus achieving the deodorization effect. Optionally, the filtering medium is activated carbon. At the same time, the activated carbon will adsorb the water vapor in the waste gas, thus forming condensed water.

[0034] The observation and monitoring unit 3 includes a condensed water observation port 31 provided outside the waste gas collection unit 1, medium inspection ports 32 arranged from top to bottom, a medium saturation monitor 33 provided in the middle of the side wall of the deodorization device, a first medium saturation monitor interface 34 provided below the lowest medium inspection port 32, a second medium saturation monitor interface 35 provided above the uppermost medium inspection port 32, and a filtering and purification area observation port 36 provided at the top of the deodorization device.

[0035] The condensed water observation port 1 is provided on the outer wall of the waste gas collection unit 1, which is used to visually monitor the liquid level of the condensed water generated after the waste gas is adsorbed, judge the collection situation of the condensed water. At the same time, it can be observed through the observation port whether there is water flowing out of the condensed water discharge port to judge whether the condensed water discharge system is working properly. If there are dirt or impurities in the condensed water collection area, they can be cleaned in time.

[0036] There are three medium inspection ports 32, which are respectively located in the high, middle and low areas of the deodorization device and are arranged in sequence from top to bottom along the outer wall of the deodorization device, and can check the filling situation of the filtering medium inside the deodorization device to ensure that the deodorization device maintains a certain deodorization performance.

[0037] The medium saturation monitor 33 accurately measures the change of the gas composition passing through the filtering medium in real time, especially the concentration change of the malodorous gas molecules. When the filtering medium gradually becomes saturated and its adsorption or filtration ability decreases, resulting in an increase in the concentration of the malodorous gas that is not effectively treated, the monitor is set with upper and lower limit alarm values. When the threshold is reached, the system will automatically trigger the alarm mechanism and send a reminder to the operator to replace the filtering medium in time through the sound and light alarm method. This immediate feedback effectively avoids the decline of the deodorization effect caused by the saturation of the medium, and also significantly reduces the frequency and cost of manual inspection, improving the overall operation efficiency.

[0038] Optionally, reminders for replacing the filter medium can also be sent to the operator via SMS notifications or a remote monitoring platform, etc.

[0039] The medium saturation monitor 33 is arranged in the upper middle part of the outer wall of the deodorization device, facilitating the operator to directly observe the specific situation of the internal filtration.

[0040] The first medium saturation monitor interface 34 and the second medium saturation monitor interface 35 are respectively arranged on one side of the medium inspection port 32 at the lowermost and uppermost sides, for connecting additional medium saturation monitoring equipment or standby sensors.

[0041] The filtration and purification area observation port 36 is arranged on one side of the gas discharge port 6. Through this observation port, the operator can directly view the cleanliness and blockage condition of the filter medium. Combining regular detection and maintenance can effectively maintain the good working state of the filtration and purification unit 3 and ensure that the treated waste gas meets the emission standards.

[0042] The deodorization device further includes an equipment identification 8, which is arranged on one side of the medium saturation monitor 33. This not only facilitates the operator to directly identify the model but also ensures the visibility and readability of the equipment identification 8. Optionally, the information on the equipment identification 8 includes the equipment name, model, serial number, production date, manufacturer, safety warning, and operation guide, facilitating the operator's daily maintenance, safe operation, and fault troubleshooting of the equipment.

[0043] The lifting rings 7 of the present utility model are equally spaced and arranged at the top of the deodorization device, and there are 4 of them. When hoisting the deodorization device, the sling or lifting chain should be correctly connected to the lifting rings and ensure a firm connection before the transfer of the deodorization device can be carried out.

[0044] In this embodiment, by setting the lifting rings 7, the deodorization device as a whole can be easily lifted by a lifting device and moved to a designated position, whether for daily maintenance, changing the site, or rapid response in an emergency. At the same time, this deodorization device is no longer restricted to a fixed position and can be flexibly adjusted according to the actual layout and operation requirements of the vacuum sewage discharge unit.

[0045] The working principle of a deodorization device cooperating with a vacuum sewage discharge unit according to an embodiment of the present utility model is as follows:

[0046] In the waste gas treatment process, the vacuum sewage discharge unit is the main source of waste gas. The waste gas generated during its operation is guided through the pipeline system to the waste gas collection interface 12. After the waste gas enters the waste gas collection unit 1, it begins to be purified and adsorbed by activated carbon. During the adsorption process, water is desorbed under the action of gas flow, thus forming condensate water. After filtration, it will be stored in the waste gas collection unit 1. As the capacity of the condensate water increases, the condensate water discharge port 5 will automatically discharge. The collected waste gas undergoes a reaction with the activated carbon in the filtration and purification unit 2, and the purified clean gas is automatically discharged from the gas discharge port 6. During the entire deodorization process, the medium saturation monitor 33 will monitor the saturation of the activated carbon. If it exceeds the set value, it will remind the operator to replace the medium.

[0047] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
