Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, specifically to an intelligent odor control system. Background Technology

[0002] As a typical nuisance, foul odor pollution has received increasing attention in recent years. Statistics show that foul odor complaints account for over 20% of all environmental complaints in my country, and nearly 50% of air pollution complaints. In terms of industry distribution, the top ten industries with the most foul odor complaints include waste disposal, animal husbandry, chemicals, rubber and plastic products, and catering. Management faces a problem of "three many and two few": many resident complaints, many industries involved, many material components, but few effective regulatory measures and few efficient control technologies.

[0003] Common odor / malodor control equipment on the market includes solid adsorption devices, incinerators, spray towers, biofilters, and high-pressure spray equipment. Among these, high-pressure spray odor removal equipment is popular due to its low investment and operating costs, convenient installation and maintenance, and good odor treatment effect. However, it has the following shortcomings:

[0004] (1) The functions are simple and single, the level of intelligence is low, and it mainly relies on manual maintenance. It cannot flexibly cope with complex odor emission conditions and cannot guarantee that the odor emission will continuously meet the standard requirements.

[0005] (2) In many working conditions, there are both odor gas components with low odor threshold and VOC components with relatively high odor threshold. In order to ensure that the odor treatment meets the standards, the dosage of odor removal reagent is excessively increased, which not only causes a sharp increase in operating costs, but also leads to the total amount of VOC at the discharge outlet exceeding the standard (some odor removal reagents contain organic components).

[0006] (3) After long-term operation, the equipment pipelines and nozzles become severely clogged, requiring regular manual inspection and maintenance, which increases the operating and maintenance costs and maintenance difficulty.

[0007] (4) The overall maximum dilution ratio is low (≤3000 times), requiring manual pre-dilution of the odor removal reagent stock solution, which involves a large workload and high labor costs.

[0008] In view of this, this utility model proposes an intelligent odor control system with good odor / malodor control effect, large dynamic dilution ratio range, low operating cost, low energy consumption, high degree of intelligence, and simple and convenient maintenance. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] Please see Figure 1-2 As shown in the figure, the intelligent odor control system described in this embodiment includes a modularly configured main unit housing; the main unit housing is equipped with a PLC control system, a two-stage automatic proportional adjustment device, a liquid storage tank, a two-stage mixing tank, a backwashing device, a micron-level atomization system, and an online odor / VOC concentration monitoring device.

[0026] Specifically, the main unit housing of the equipment is made of stainless steel, which is highly corrosion-resistant. It is installed in a fixed location at the odor treatment site, such as in a workshop, factory, or near the treatment facility. The main unit housing serves as the main frame, providing physical support and protection, while integrating other functional modules to ensure the overall stability and safety of the system. The water inlet pipeline, chemical dosing pipeline, cleaning pipeline, and high-pressure liquid outlet pipeline are all made of high-pressure resistant stainless steel pipes to prevent bursting during long-term high-pressure operation.

[0027] The two-stage automatic proportioning device includes three independently installed automatic dilution proportioning pumps, which connect the inlet water pipeline to the storage tank and the two-stage mixing tank through the automatic dilution proportioning pumps and the corresponding dosing pipelines.

[0028] Specifically, the flow rate is controlled by an electrically controlled switch valve at the inlet of the automatic dilution proportioning pump. The adjustable proportioning ranges of the three automatic dilution proportioning pumps are 0.2-2%, 0.4-4%, and 1-10%, respectively, with a maximum combined dilution ratio of 5000 times. The control switch valve is an electrically controlled switch valve installed on a branch of each automatic dilution proportioning pump. By adjusting the flow rate of the proportioning pump, the polymeric odor decomposing agent is mixed and diluted with water, with a maximum dilution ratio of 5000 times, meeting the dilution requirements under different operating conditions.

[0029] The storage tank and the two-stage mixing tank are connected to the two-stage automatic proportioning device and the atomization system through pipelines. The storage tank is used to store the original liquid of the polymeric odor decomposing agent, and the mixing tank is used to store the diluted mixture. The storage tank provides storage and supply of the polymeric odor decomposing agent. The two-stage mixing tank ensures uniform concentration of the mixture through step-by-step dilution, providing a stable supply of agent to the atomization system.

[0030] To further explain, the storage tank is used to store a polymeric odor decomposing agent for odor / malodor control;

[0031] The two-stage mixing tanks are configured such that the first mixing tank stores the polymeric odor decomposing agent mixture after pre-mixing and diluting with water, and the second mixing tank stores the polymeric odor decomposing agent mixture after secondary dilution in the first mixing tank.

[0032] The backwashing device includes a cleaning pipeline and a control valve. It can be set to periodically clean the spray pipeline and nozzles at set times in the system. The cleaning cycle is set through a PLC control system to prevent blockage, ensure the long-term stable operation of the atomization system, and reduce maintenance costs.

[0033] The atomization system includes a high-pressure plunger pump, a high-pressure outlet pipe, a spray bar / spray ring, and a micron-level atomizing nozzle assembly. The high-pressure plunger pump operates at a pressure range of 4-8 MPa, which can make the atomization effect of the mixed liquid more ideal. One end of the high-pressure outlet pipe is connected to the high-pressure plunger pump, and the other end is connected to the spray bar / spray ring. The spray bar / spray ring represents different application forms of spraying, but this utility model is not limited to these forms. The micron-level atomizing nozzle includes vortex nozzles, fan-shaped nozzles, and impact nozzles, which are installed on the spray bar / spray ring, with a uniform layout, an atomized particle size of 3-30 μm, good atomization effect, and sufficient odor removal reaction.

[0034] The atomization system includes a high-pressure plunger pump, which connects to a mixing tank and a spray bar / ring. The spray bar or ring is installed in the odor control area (such as a workshop, air duct, or spray tower), and the nozzle assembly is evenly distributed on the spray bar or ring. The high-pressure plunger pump atomizes the diluted mixture into tiny particles with a diameter of 3-30 μm, which are then sprayed onto the odor-causing gas, achieving efficient odor removal and VOC treatment.

[0035] The online odor and VOC concentration monitoring device is installed at the emission outlet or monitoring point of the odor control system. It is connected to the PLC control system via cable. Based on the real-time monitored odor and VOC concentration data, it feeds back to the PLC control system to dynamically adjust the dilution ratio and spray volume. While ensuring that the odor and VOC concentrations meet the emission standards, it also achieves energy saving and consumption reduction.

[0036] Liquid level alarm devices are installed in the storage tank and the two-stage mixing tank. The liquid level alarm device includes an electronic float liquid level alarm device, which is connected to the PLC control system via a cable to monitor the liquid level status in real time. When the liquid level is lower than the set value, an alarm is automatically triggered and liquid is replenished to prevent the water pump from running dry and being damaged, thus ensuring the normal operation of the system.

[0037] To further explain, the volume of the storage tank is 20-50L; the two-stage mixing tank includes two mixing tanks, each with a volume of 40-60L.

[0038] This embodiment ensures efficient system operation and wide applicability through a rational layout of the module installation methods. The modules work collaboratively to achieve intelligent, efficient, and low-maintenance odor control, making it suitable for odor control needs in various industries and scenarios.

[0039] The PLC control system receives real-time data from the online odor and VOC concentration monitoring device and dynamically adjusts parameters such as dilution ratio and spray volume according to preset programs to achieve intelligent control.
