[0034] The following description is used to explain the present application in detail so as to enable those skilled in the art to implement the present application. The preferred embodiments in the following description are only used as examples, and other obvious modifications can be thought of by those skilled in the art. The basic principles defined in the following description can be applied to other embodiments, modifications, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present application.

[0035] Referring to Figs. 1-2 The present application provides a technical solution: a system for removing odor from unorganized waste gas, comprising:

[0036] The odor-removing spray system host 2 comprises a liquid storage tank, which is adapted to inject an odor-eliminating agent 1 formed by mixing water and concentrated stock solution in a proportion-adjustable manner. The side of the liquid storage tank is provided with a water inlet interface and a medicine inlet interface. The water inlet interface is connected with a high-pressure pump, and the medicine inlet interface is connected with a medicine feeding pump. In use, the concentrated stock solution is diluted by the high-pressure pump and the medicine feeding pump of the odor-removing spray system host 2 in cooperation. Specifically, the concentrated stock solution is injected into the liquid storage tank by the medicine feeding pump, and water is injected into the liquid storage tank by the high-pressure pump. The stock solution in the liquid storage tank is diluted to the odor-eliminating agent 1 at a working concentration. Specifically, the odor-eliminating agent 1 adopts a high-molecular compound formula.

[0037] The spray pipeline 3 is connected with the liquid storage tank and is provided with a pump body between the spray pipeline 3 and the liquid storage tank. The odor-eliminating agent 1 diluted to the working concentration is delivered to the spray area through the spray pipeline 3. The spray pipeline 3 comprises a main pipe and branch pipes. The liquid storage tank, the main pipe, and the branch pipes are connected in sequence. The branch pipes are distributed on the outside of the spray area, that is, the main pipe extends from the odor-removing spray system host 2 and is divided into multiple branch pipes. The branch pipes are designed to match the production workshop structure and system installation position. High-pressure atomizing nozzles 4 are arranged on the branch pipes at intervals and face the spray area. By installing the high-pressure atomizing nozzles 4 in the spray pipeline 3 at intervals, high-pressure atomizing spraying of the odor-eliminating agent 1 is realized, and regional and accurate coverage of the odor of unorganized waste gas in the workshop is achieved.

[0038] The system for removing odor from unorganized waste gas further comprises a sensor sensing module, an intelligent control module, and a spray execution module. The intelligent control module controls the spray execution module according to the data obtained by the sensor sensing module to adjust the spray frequency and the spray concentration.

[0039] Specifically, the sensor sensing module is configured to trigger and send an sensing signal to the intelligent control module when a target object approaches the spray area to a preset distance. The intelligent control module controls the high-pressure atomizing nozzles 4 to start through the spray execution module.

[0040] When the sensor sensing module senses that the target object is away from the spray area to a preset distance, the intelligent control module controls the high-pressure atomizing nozzles 4 to close through the spray execution module.

[0041] In the embodiment, the target objects are vehicles and production materials, when the vehicles and production materials are within a distance of about 1m from the spraying area, the sensor sensing module sends an induction signal to the intelligent control module, and the spraying execution module starts spraying;

[0042] When the sensor sensing module senses that the vehicles and production materials are again away from the spraying area by a distance greater than 2m, the spraying execution module stops spraying.

[0043] The sensor sensing module is configured to send an induction signal to the intelligent control module when no materials are monitored to pass through, and the intelligent control module controls the high-pressure atomizing nozzle 4 through the spraying execution module to work for a preset spraying time and spraying interval. In the embodiment, when the sensor sensing module detects that the vehicles are empty or only personnel pass through, the intelligent control module switches the spraying execution module to a low-frequency mode, and starts spraying once every 5min, and each spraying lasts for 2min.

[0044] The sensor sensing module is configured to monitor the odor concentration in the spraying area in real time, and when the odor concentration in the spraying area environment reaches a set threshold, the sensor sensing module sends an induction signal to the intelligent control module, and the intelligent control module controls the high-pressure atomizing nozzle 4 through the spraying execution module to start, so as to achieve the effect of removing odor as soon as it is generated.

[0045] The spraying area is the entrance and exit of a production workshop or the inside of a workshop;

[0046] In one of the embodiments, the spraying area is the entrance and exit of a production workshop, and the odor-removing spraying system host 2 further comprises:

[0047] An air curtain machine 5 is arranged to form an air curtain area, the air curtain area is arranged outside the spraying area in the horizontal direction, and the air curtain area covers the spraying area in the vertical direction. This embodiment is suitable for the entrance and exit of a production workshop, the air curtain machine 5 and the spraying pipeline 3 are designed in combination to form an odor-removing spraying wall, which improves the accuracy of the spraying area and the stability of the operation effect, ensures that the odor-removing agent 1 is not diluted or blown away, effectively reduces the escape of odor in the workshop, and at the same time promotes the air circulation in the workshop;

[0048] When the spraying pipeline 3 is installed at the entrance and exit of a production workshop, the installation point of the spraying pipeline 3 is the inside of the entrance and exit passage, and extends inward. The coverage range of the spraying area, the wiring of the spraying pipeline 3, the spacing of the high-pressure atomizing nozzle 4, the spraying angle, and the spraying amount are all designed according to the structure and production mode of the entrance and exit of the production workshop, so as to realize efficient spraying while avoiding liquid accumulation on the ground.

[0049] In another embodiment, the spraying area is the interior of the workshop, and the unorganized waste gas odor removal system is applied to the interior of the workshop. Compared with the previous embodiment, the air curtain machine 5 is not needed to assist in forming a spraying wall.

[0050] The orientation, number, wind speed and layout form of the air curtain machine 5 are adjusted according to the design of the spraying pipeline 3 and the spraying area.

[0051] The core of the unorganized waste gas odor removal system to achieve odor removal is the odor eliminating agent 1. The odor eliminating agent is formed by diluting a high-concentration stock solution with water. The high-concentration stock solution is added to the liquid storage tank of the odor removal spraying system host 2. The high-concentration stock solution is diluted by a high multiple through the cooperation of the dosing pump and the high-pressure pump built in the odor removal spraying system host 2. The single-use period is long. The unorganized fugitive waste gas odor in the industrial production workshop can be diluted at a high multiple. The dilution range of the high-concentration stock solution is 100:1 to 2000:1. The odor typical components such as sulfur-containing compounds and nitrogen-containing compounds can achieve broad-spectrum, high-efficiency purification and no environmental damage.

[0052] Further, the water inlet interface is connected with the water tank. The liquid level alarm module is arranged in the liquid storage tank and the water tank. When the liquid level in the liquid storage tank and the water tank is lower than the set value, automatic water replenishment / reminding is performed.

[0053] Further, the high-pressure atomizing nozzle 4 is detachable, that is, the high-pressure atomizing nozzle 4 and the spraying pipeline 3 are detachably connected. The high-pressure atomizing nozzle 4 is designed with an anti-clogging structure to solve the problems of easy clogging and secondary pollution of the traditional spraying system.

[0054] In summary, the unorganized waste gas odor removal system can achieve efficient purification of various components of the waste gas odor generated in the industrial scene by using the odor eliminating agent with a high-molecular compound formula. The system has broad-spectrum and high efficiency and can efficiently treat the unorganized waste gas odor generated in the industrial production workshop.

[0055] The unorganized waste gas odor in the industrial production workshop mainly escapes to the external environment through the entrance and exit of the workshop. Therefore, the spraying area of the odor treatment system is designed to extend to the inside of the workshop with the entrance and exit as the interface. The air curtain machine cooperates with the spraying pipeline to build an odor removal spraying wall to solve the problem of the escape of the unorganized waste gas odor in the workshop to the external environment with the smallest spraying coverage.

[0056] The spraying pipeline can be erected on the top of the workshop according to the arrangement of the production equipment and the production line to achieve the removal of the unorganized waste gas odor generated in the workshop as soon as the odor is generated. The system can complement the odor treatment system installed at the entrance and exit.

[0057] The high-pressure atomizing nozzle is designed with an anti-blocking structure and can be disassembled for maintenance;

[0058] The odor-removing system for unorganized waste gas is designed with "PLC + sensor", and can intelligently adjust the spraying frequency by combining the internet and AI technology, dynamically adjust the spraying frequency and the dilution concentration of the decomposition agent, and realize the "removing odor as soon as it is generated" for the unorganized waste gas in the production workshop, thereby reducing the operation investment. Meanwhile, the system can automatically predict the possible high-concentration odor burst period through the operation mode, dynamically adjust the spraying frequency and the concentration of the agent, and realize the precise and intelligent operation.

[0059] The odor-removing system for unorganized waste gas can realize the efficient, accurate, broad-spectrum and low-cost treatment of the unorganized waste gas odor in the industrial production workshop, and can meet the treatment needs of the rubber tire, chemical, food processing and other industries for the unorganized odor in the production workshop.
