Problems solved by technology

[0003] The traditional underground public restroom adopts the top exhaust method, and the odor in the restroom is easily inhaled by the human body from the bottom up to the respiratory system, which poses a health hazard to the human body
In addition, in some underground spaces such as subway stations and shopping malls, the exhaust air of toilets is directly discharged from the ground through shafts, which is relatively close to the fresh air of the air-conditioning system. The material is circulated and transported in a closed underground environment, causing secondary pollution
[0004] Moreover, for the extraction and treatment of odor in underground public toilets, the staff needs to judge according to the flow of people and the environmental conditions of the toilet, and then operate the ventilation system to achieve work, which leads to insufficient timely treatment of odor
[0005] It can be seen that the current exhaust method of underground public toilets is not reasonable enough, and the immediacy of odor treatment cannot be said to be sufficient, and there is room for further improvement

no. 1 Embodiment approach

[0038] In the first embodiment, the present invention provides an underground public restroom odor control and treatment system. Such as figure 1 As shown, the system at least includes an odor detection device 1 and an odor discharge device 2, the vertical height of the odor detection device 1 from the ground of the toilet is H1, and the distance between the odor discharge device 2 and the toilet is The vertical height of the ground is H2, and the average height of the adult population where the public toilet is located is H, then H, H1 and H2 have the following relationship: H>H1≥H2.

[0039] bad smell

[0040] The odor in the bathroom is generally caused by the mixed gas produced by the fermentation and metabolism of feces and excreta. Since these substances are often compounds containing nitrogen, sulfur, hydrogen, oxygen and other elements, ammonia will be produced through complex chemical reactions. Gas, hydrogen sulfide and other gases with strong pungent odor, the ...

no. 2 Embodiment approach

[0058] In the second embodiment, the present invention provides a treatment method for odor control in underground public restrooms. The odor control treatment method includes the odor control treatment system according to the first embodiment, and the method includes the following steps:

[0059] 1) the step of the odor detection device 1 detecting the odor concentration of the public toilet;

[0060] 2) The step of the odor exhausting device 2 exhausting the gas in the public toilet, and optionally, the step of using the odor cleaning device 3 to mask the odor.

[0061] In the above method, when the odor detection device 1 in step 1) detects that the odor concentration in the public toilet is higher than the standard value, step 2) is started. Specifically, when the odor detection device 1 detects that the odor concentration of the public toilet is higher than the standard value, a signal is transmitted to the control system of the odor discharge device 2, and the control s...

Abstract

The invention relates to a control treatment system and method for the odor of an underground public toilet. The system at least comprises an odor detecting device and an odor discharging device, thevertical height from the odor detecting device to the ground of the toilet is H1, and the vertical height from the odor discharging device to the ground of the toilet is H2, the average height of adults in the place where the toilet is located is H, and H, H1 and H2 have the following relation: H) H1> / = H2.

Description

technical field [0001] The invention relates to the control and treatment of odor, in particular to an underground public toilet odor control and treatment system and a control treatment method, belonging to the technical field of odor treatment. Background technique [0002] Public toilets are set up in underground spaces such as subways and underground shopping malls. Due to the exhaust design, cleaning management, and retention or exhaust of septic tank sewage in public toilets, etc., the pollution of odor and pathogenic bacteria is serious. Odor and the pollution of pathogenic bacteria will spread along with the people coming in and out and the air circulation, thus causing a large area of ​​infection. The two most representative gas pollutants in the bathroom are hydrogen sulfide and ammonia. They are not only the cause of peculiar smell, but also greatly affect human health. For example, when the hydrogen sulfide content in the air reaches 30-40mg / m 3 When the content...
