During the wastewater treatment process, it is often accompanied by unpleasant odors. These odors mainly come from the decomposition of organic matter, sulfur compounds, nitrogen compounds, etc.

[0003] Currently, most medium- and large-scale sewage treatment plants use ozone deodorization equipment. Small rural sewage treatment plants are designed specifically to treat rural domestic sewage, aiming to improve rural environmental quality and protect water resources. Due to design scale and cost-effectiveness considerations, they do not have dedicated deodorization systems. Furthermore, the ozone deodorization equipment used in medium- and large-scale sewage treatment plants requires large-scale spraying processes, resulting in large footprints and high operating and maintenance costs, making it unsuitable for small rural sewage treatment plants. Therefore, a deodorization system that is suitable for small-scale rural sewage treatment plants and has low operating costs is needed.

Similarly, when gas treatment begins, manual judgment can lead to significant errors, making the results difficult to guarantee. Therefore, a deodorizing device and treatment system are needed that effectively adsorbs waste gas odors, can be automatically controlled, and automates overall gas treatment, achieving effective treatment results.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The purpose of the utility model is to provide a deodorizing device and treatment system to solve the problems existing in the above-mentioned prior art, so that the waste gas odor adsorption effect is good, the operating cost is low, and it can be automatically controlled and the overall gas treatment is automated.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] Example 1

[0032] like Figure 1-Figure 3 As shown, the utility model provides a deodorizing device, including

[0033] The adsorption box includes an activated carbon chamber 1 for storing activated carbon. The chamber 1 is connected to the adsorption box's air inlet 3 and outlet 4. The air inlet 3 allows the deodorized gas to enter, while the outlet 4 is exposed to the atmosphere. The fan introduces the deodorized gas into the activated carbon chamber 1. The gas analyzer 19 is located at the deodorized gas inlet and analyzes its composition. It can output different electrical signals based on changes in the deodorized gas composition. The AC contactor 20 is electrically connected to the output of the gas analyzer 19 and the control terminal of the fan. The AC contactor 20 controls the fan based on the different electrical signals output by the gas analyzer 19. The adsorption box is compact and utilizes activated carbon to adsorb odorous gases, resulting in effective adsorption and low cost. It is suitable for small rural sewage treatment plants, for example. As the composition of the deodorized gas changes, the gas analyzer 19 outputs different electrical signals, which the AC contactor 20 uses to control the fan. For example, when the concentration of odorous substances in the gas to be deodorized suddenly increases, the fan speed can be adjusted in time to speed up the speed of the gas to be deodorized passing through the activated carbon holding chamber 1, ensuring that more gas to be deodorized is processed in a short time, and the fan operation is dynamically controlled according to the composition of the gas to be deodorized, thereby effectively maintaining the stability of the deodorization effect. When there are fewer odorous components in the gas to be deodorized, the fan speed can be reduced to reduce energy consumption. Dynamic adjustment according to actual needs avoids the fan from being in a high-power operating state all the time, saving energy costs. An automated control loop is formed between the gas analyzer 19, the AC contactor and the fan. The entire system does not require frequent manual intervention and can automatically adjust according to changes in the composition of the gas to be deodorized to achieve intelligent operation. It can not only improve processing efficiency, but also reduce errors and labor intensity caused by manual operation.

[0034] It should be noted that by analyzing the composition of the gas to be deodorized using the gas analyzer 19, the type and content of substances to be removed can be determined in real time. This information allows for more targeted selection of activated carbon and adjustment of the adsorption chamber operating parameters. Different types of activated carbon have varying adsorption effects on different components of the gas to be deodorized. Selecting the type of activated carbon based on the data displayed by the gas analyzer 19 can maximize deodorization efficiency.

[0035] In some embodiments, the adsorption box further includes an air inlet 5 and an air outlet 6, the air inlet 5 and the air outlet 6 are respectively fixedly connected to the two ends of the activated carbon holding chamber 1, wherein the activated carbon holding chamber 1 is columnar, the air inlet 5 and the air outlet 6 are both conical, the large ends of the air inlet 5 and the air outlet 6 are respectively connected to the two ends of the activated carbon holding chamber 1, the small end of the air inlet 5 is the air inlet 3 for connecting to the exhaust port of the gas to be deodorized, and the small end of the air outlet 6 is the air outlet 4 for passing the treated gas to the atmosphere. The air inlet 5 is conical, and its large end is connected to the columnar activated carbon holding chamber 1. When the gas to be deodorized enters the air inlet 5 from the air inlet 3, the conical structure can make the gas gradually diffuse and evenly distribute the gas over the entire cross-section of the activated carbon holding chamber 1, avoiding the situation where the local airflow is too large or too small, and can ensure sufficient contact between the activated carbon and the gas to be deodorized, thereby improving the deodorization efficiency. The outlet end 6 is also conical. After the gas passes through the activated carbon chamber 1 and completes the adsorption process, the conical outlet end 6 allows the gas to gradually converge and discharge, helping to reduce gas turbulence at the outlet and allowing the gas to flow smoothly into the atmosphere after convergence, ensuring the stability of the deodorization effect. Since the inlet end 5 allows the gas to enter the activated carbon chamber 1 in an evenly distributed manner, the outlet end 6 gradually decreases in diameter to avoid rapid gas discharge. The design of the inlet end 5 and the outlet end 6 allows the residence time of the gas to be deodorized in the activated carbon chamber 1 to be relatively prolonged, thereby increasing the contact time between the gas to be deodorized and the activated carbon, which is conducive to the activated carbon more fully adsorbing the odor components in the gas to be deodorized, thereby improving the adsorption effect.

[0036] It should be noted that, for ease of installation and to ensure effective use, the activated carbon chamber 1 is preferably cylindrical, and the air inlet 5 and air outlet 6 are preferably conical. The activated carbon chamber 1 may also be other types of columns, such as a triangular prism, a quadrangular prism, or other polygonal prisms, and the air inlet 5 and air outlet 6 need to be truncated pyramids corresponding to the prism.

[0037] In some embodiments, the fan is a centrifugal fan 8 connected to the air outlet 6 of the adsorption chamber, directing the gas through the adsorption chamber and out to the atmosphere. The airflow generated by the centrifugal fan 8 at the air outlet 6 has a certain directionality and pressure, effectively preventing the discharged treated gas from flowing back into the adsorption chamber, thereby preventing the treated gas from mixing with untreated gas and reducing the deodorization effect. Furthermore, the steady output of the centrifugal fan 8 ensures that the airflow is discharged at a relatively stable speed and pressure, avoiding pulsation and turbulence.

[0038] In some embodiments, a mounting bracket 9 is disposed below the centrifugal fan 8. The top end of the mounting bracket 9 is fixedly connected to the centrifugal fan 8, and the bottom end is fixed to the ground. The mounting bracket 9 secures the centrifugal fan 8 to the ground. During fan operation, especially at high speeds, vibrations and unbalanced forces are generated. The mounting bracket 9 effectively resists these forces, preventing the centrifugal fan 8 from shaking, shifting, or even toppling, thereby ensuring the stable operation of the centrifugal fan 8 and, consequently, the entire deodorization system.

[0039] In some embodiments, the deodorizing device 101 further includes a charcoal drawer 2, which is retractable from the activated carbon chamber 1 and is used to store activated carbon. This pull-out design makes replacing the activated carbon extremely easy. When the activated carbon needs to be replaced, there's no need to disassemble the entire adsorption chamber. Simply pull out the charcoal drawer 2, remove the old activated carbon, and replace it with a new one, significantly saving replacement time and labor costs.

[0040] In some embodiments, there are multiple charcoal drawers 2, and they are arranged in sequence along the height direction of the activated carbon accommodating chamber 1. The multiple charcoal drawers 2 are distributed along the height direction, so that the gas to be deodorized can be adsorbed in layers when passing through the activated carbon accommodating chamber 1. The activated carbon at different height positions can adsorb pollutants of different particle sizes and different volatility in the gas to be deodorized, thereby improving the efficiency and accuracy of adsorption and more effectively removing various odor components in the gas to be deodorized. At the same time, if the activated carbon in a certain charcoal drawer 2 is found to be abnormal (such as contaminated, damp, etc.) during operation, the drawer can be pulled out separately for processing without having to operate other normal activated carbon parts, thereby improving the targetedness and flexibility of maintenance. Moreover, the arrangement of multiple charcoal drawers 2 along the height direction fully utilizes the vertical space of the activated carbon accommodating chamber 1 and increases the contact area between the activated carbon and the gas to be deodorized. Without increasing the floor space of the equipment, more activated carbon can be accommodated, thereby improving the processing capacity of the entire deodorization device 101.

[0041] In some embodiments, the deodorizing device 101 further includes a bracket 7, which is disposed below the activated carbon containing chamber 1. The top of the bracket 7 contacts the activated carbon containing chamber 1, and the bottom is fixed to the ground. The activated carbon containing chamber 1 is fixed to the ground by the bracket 7, and the structure is stable and not prone to tilting, deformation, etc.

[0042] In some embodiments, gas analyzer 19 is an electrochemical gas analyzer that measures gas composition using electrochemical reactions occurring at electrodes. The gases analyzed primarily include common malodorous substances such as hydrogen sulfide, ammonia, methyl mercaptan, dimethyl sulfide, carbon disulfide, styrene, and dimethyl disulfide. The analyzer's principle is based on the electrochemical reactions of gas molecules at electrodes, which produce changes in the current signal. This electrical signal is transmitted back to the AC contactor via a circuit. The AC contactor controls the start and stop of the centrifugal fan and its speed, forming a feedback control circuit that automatically adjusts the centrifugal fan's operation based on actual conditions.

[0043] Example 2

[0044] This embodiment also provides a treatment system, including a forebay 10, a regulating tank 11, an integrated sewage tank and the deodorization device 101 as described in Example 1. The forebay 10, the regulating tank 11 and the integrated sewage tank are connected in sequence. The forebay 10 is used for preliminarily intercepting solid matter. The regulating tank 11 can adjust the water volume and sedimentation. The integrated sewage tank is connected to the regulating tank 11 through a water pump 12. The integrated sewage tank is used to treat sewage, and an exhaust end and a drainage end are provided on the integrated sewage tank. The exhaust end is provided with an exhaust port for gas to be deodorized and is connected to the deodorization device 101, and the drainage end is used to discharge treated water.

[0045] In some embodiments, the integrated sewage tank includes an anoxic tank 13, an aerobic tank 14, a membrane tank 15, a sedimentation tank 16, a sludge storage tank 17 and an outlet tank 18 connected in sequence. The anoxic tank 13 and the aerobic tank 14 use anaerobic microorganisms and aerobic microorganisms to treat sewage respectively, the membrane tank 15 uses membranes to treat sewage, the sedimentation tank 16 is used for sedimentation, the sludge storage tank 17 is used to store sludge, and the outlet tank 18 is used to discharge qualified treated water.
