[0035] Example 1

[0036] Referring to Figures 1-2 The embodiment provides a biochemical treatment deodorization device based on the BIM model, which comprises:

[0037] The biological deodorization tower 1 is used for two-stage deodorization of odorous gases. Specifically, the biological deodorization tower 1 comprises a pre-wash tank 101 and a biological filter tank 102. The pre-wash tank 101 has a gas inlet pipe at the top and a plastic filler area 103 in the middle. The biological filter tank 102 also has a gas outlet pipe at the top and a biofilter area 104 in the middle. The pre-wash tank 101 and the biofilter tank 102 are connected, and the connection point between the pre-wash tank 101 and the biofilter 102 is lower than the plastic filler area 103 and the biofilter area 104.

[0038] The fan 2 is used to collect and transport the odor. Specifically, the air outlet of the fan 2 is connected to the top of the pre-wash tank 101 through a pipeline, and the air inlet of the fan 2 is connected to the odor pipeline.

[0039] The circulating water tank 3 is connected to the bottom of the pre-wash tank 101 via a pipe. Specifically, one end of the pipe extends to the bottom of the pre-wash tank 101, and the other end extends into the circulating water tank 3, with the other end at a lower elevation. The circulating water tank 3 stores spray water and also has a pipe connecting to the outside world for replenishing water or discharging wastewater.

[0040] The inlet of the spray pump 4 is connected to the circulating water tank 3 via a pipe. Specifically, one end of the pipe extends to the bottom of the circulating water tank 3, and the other end is connected to the inlet of the spray pump 4. The outlet of the spray pump 4 is connected to the upper drainage pipe 6. The tops of the pre-wash tank 101 and the biological filter 102 are both equipped with nozzles, which are connected to the upper drainage pipe 6 via a connecting branch pipe 8.

[0041] The control cabinet 5 is electrically connected to the fan 2 and the spray pump 4 , and is used to control the start and stop of the fan 2 and the spray pump 4 .

[0042] Based on the above structure, after the fan 2 is turned on, the odor to be treated is pumped to the top of the pre-wash tank 101 through the fan 2, moves downward in the pre-wash tank 101, and after pretreatment in the plastic filler area 103, enters the biological filter 102. In the biological filter 102, the odor moves upward, and after secondary treatment in the biological filter material area 104, reaches the top of the biological filter 102 and is finally discharged into the atmosphere.

[0043] At the same time, by starting the spray pump 4, the spray pump 4 pumps the spray water in the circulating water tank 3 to the upper exhaust pipe 6, and then is transported to each spray head through the connecting branch pipe 8 and is sprayed out, so that the plastic filler area 103 and the biological filter material area 104 are humidified and sprayed, so that the plastic filler area 103 and the biological filter material area 104 maintain appropriate temperature and humidity, and the spray water can flush the metabolic products generated in the microbial degradation process or supplement the nutrients required for microbial growth. Among them, the spray water collected at the bottom of the pre-washing pool 101 has less impurities and can be returned to the circulating water tank 3 for storage and reuse. The spray water collected at the bottom of the biological filter pool 102 has more impurities and can be directly discharged later.

[0044] In the embodiment, the plastic filler area 103 can preliminarily remove impurities by pretreating the odor. Moreover, the plastic filler has high mechanical strength and is not easy to be corroded, and has a long service life. The plastic filler area 103 can share part of the load, so that the subsequent biological filter material area 104 has a smaller load, thereby improving the overall service life of the device.

[0045] In addition, in the embodiment, the following advantages are obtained by selecting the biological filter material for secondary treatment of the odor:

[0046] (1) The biological filter material has very good odor treatment effect and high removal rate of odor-causing substances, and can meet strict environmental protection requirements;

[0047] (2) The biological filtration does not use harmful and dangerous chemicals, and the filter material used for filtration is entirely derived from natural plant remains, and the energy demand is the lowest among many methods;

[0048] (3) Microorganisms can grow relying on organic matter in the filler and odor-causing components in the airflow, the biological treatment process does not discharge harmful substances, and the final product is also benign, and the implementation of the project is safe and reliable;

[0049] (4) The operation adopts full-automatic control and is very stable without manual operation. The system has few easy-to-damage components, and the system maintenance and management project is very simple, basically realizes unmanned management, and workers only need to patrol whether the machine has a fault;

[0050] (5) Two-stage biological deodorization is adopted, and the deodorization effect is guaranteed.

[0051] The device provided in the embodiment further includes a base plate 9, and the biological deodorization tower 1, the fan 2, the circulating water tank 3, the spray pump 4, and the control cabinet 5 are arranged on the base plate 9.

[0052] The BIM model is used to integrate each component into a modular form, the size of the pipeline can be adjusted parametrically, and other valves can be automatically adapted to changes, improving the flexibility of the design. The module components of the biochemical treatment deodorization device can be adjusted according to the actual situation of the design, and the adaptability is good, which can be used between different projects, migration and modification. The whole module design is adopted to create a fine model, which can be quickly drawn, collision checked and used to guide the construction of the biochemical deodorization device.

[0053] Referring to Figure 3 In order to improve the cleanliness of the backflow in the bottom of the pre-washing tank 101 to the spraying water in the circulating water tank 3, the device provided by the embodiment further comprises a filter 7, which is arranged between the inlet of the spraying pump 4 and the circulating water tank 3. The filter 7 can be a blue filter, which can not only effectively improve the cleanliness of the spraying water, but also reduce the load of the plastic filler area 103 and the biological filter tank 102.

[0054] A butterfly valve is arranged at the inlet of the filter 7, which is used to control the backflow of the spraying water in the circulating water tank 3.

[0055] The device provided by the embodiment comprises two spraying pumps 4, which are arranged in parallel. Specifically, the inlets of the two spraying pumps 4 are communicated with the outlet of the filter 7, and the outlets of the two spraying pumps 4 are communicated with the upper discharge pipe 6. One of the two spraying pumps 4 is used as a backup, and the other one is used for normal operation, which is convenient for the maintenance operation of the spraying pump 4 in special circumstances. The spraying pump 4 can be installed on the base plate 9 through a shock-absorbing plate. Specifically, the shock-absorbing plate is fixed on the base plate 9, and the two spraying pumps 4 are installed on the shock-absorbing plate through bolts, which can reduce the vibration effect of the pump.

[0056] A rubber flexible joint, a check valve and a butterfly valve are sequentially arranged at the outlet of the spraying pump 4. The check valve and the butterfly valve are used to ensure the normal operation of the spraying pump 4 and prevent the spraying water in the upper discharge pipe 6 from flowing back to the outlet of the spraying pump 4. A rubber flexible joint is arranged at the inlet of the spraying pump 4. The arrangement of the rubber flexible joint facilitates the connection of the spraying pump 4 with pipes of different specifications.

[0057] A spring pressure gauge is arranged on the upper discharge pipe 6, which can detect the pressure of the upper discharge pipe 6.

[0058] The connecting branch pipes 8 are provided with butterfly valves and electric butterfly valves, and the electric butterfly valves are electrically connected with the control cabinet 5. The butterfly valves and the electric butterfly valves are used to control the opening and closing of the connecting branch pipes 8, and then control the opening and closing of the corresponding spray heads. For example, opening the butterfly valves and the electric butterfly valves on the connecting branch pipes 8 communicated with the spray heads in the pre-washing tank 101 can open the spray heads in the pre-washing tank 101 for spraying; closing the butterfly valves and the electric butterfly valves on the connecting branch pipes 8 communicated with the spray heads in the pre-washing tank 101 can close the spray heads in the pre-washing tank 101. The staff can also manually control the butterfly valves from the outside to control the opening and closing of the corresponding spray heads.

[0059] Referring to Figure 4 , in order to facilitate the discharge of sewage in the bottom of the pre-washing pool 101, the biological filter pool 102, the device provided by the embodiment also includes a sewage pipe 10, which is in communication with the bottom of the pre-washing pool 101 and the bottom of the biological filter pool 102. The sewage pipe 10 is provided with a corresponding valve. Through the sewage pipe 10, the sewage in the bottom of the pre-washing pool 101 and the bottom of the biological filter pool 102 can be discharged.
