Embodiment 1

[0048] like figure 1 Shown, a kind of ventilating and filtering method of underground pipeline gallery flow; Described method comprises the following steps;

[0049] S1: Use a portable air detector to regularly detect the air quality in the underground pipe gallery;

[0050] S2: When the detector detects that the air quality index in the underground pipe gallery is poor, use a ventilation device for ventilation; ventilation includes the intake process and exhaust process; the intake process includes the following steps: a. Turn on the motor, The motor drives the connecting rod of the crankshaft, further drives the moving rod and the sliding plate to reciprocate in the air intake cavity, and the intake air is formed through the first air intake hole, the second air intake hole, the first air outlet hole, and the second air outlet hole. Accelerate the rate of natural air entering the underground pipe gallery to ensure that there is sufficient fresh air in the underground pipe g...

Embodiment 2

[0058] On the basis of Example 1, as Figure 2-6 As shown, a ventilation device for the flow of underground pipe corridors is adopted; it includes a housing 1; a first partition 2 is provided inside the housing 1, and an exhaust pipe is provided above the first partition 2 3. The exhaust pipe 3 is connected with an exhaust fan 4, through which the exhaust is exhausted; one end of the exhaust pipe 3 is connected with an exhaust cover 5, and the exhaust cover 5 is inlaid with the housing 1 connection; the other end of the exhaust pipe 3 is connected with an intake cover 6, and the intake cover 6 is inlaid with the housing 1; a second partition 7 is provided below the first partition 2, and the second partition 7 A closed air intake cavity 13 is formed on one side close to the housing 1; a third partition 8 is provided on the other side of the second partition 7, and a vent 19 is provided at the center of the third partition 8; One side of the third partition 8 away from the sec...

Embodiment 3

[0063] On the basis of Embodiments 1 and 2, the first filter screen 20 is a HEPA high-efficiency filter screen, which can filter a large amount of particulate pollutants contained in the natural air, and the filter diameter is 0.3 μm; There are several macromolecules in it.

[0064] In order to ensure the air quality in the underground pipe gallery, the fresh air volume V of the ventilation device and the carbon dioxide concentration C in the underground pipe gallery 1 and the carbon dioxide content in the fresh air, and the release amount of carbon dioxide n inhaled by personnel satisfy the following relationship:

[0065] V=α·(n / (C 1 -C 2 ));

[0066] In the above formula, α is the relationship coefficient, the value range is 0.569-3.323; V unit m 3 / h; C 1 、C 2 , The unit of n is ppm.

[0067] In order to ensure the air humidity and reasonable temperature in the underground pipe gallery, the temperature of the underground pipe gallery is adjusted through this device,...

Abstract

The invention discloses a method for ventilation and filtering of logistics in an underground pipe gallery; the method includes the following steps: S1: using a portable air detector to regularly detect the air quality in the underground pipe gallery; S2: when the detector detects the air quality in the underground pipe gallery When the quality index is poor, use a ventilation device for ventilation treatment; use a portable air detection device for detection, and when the air quality of the underground pipe gallery is qualified, suspend the ventilation device; S4: Confirm the air quality in the underground pipe gallery The index is the level of safety and comfort, and the ventilation is completed; the ventilation efficiency is high, and the air in the underground pipe gallery is purified to improve the air quality in the underground pipe gallery and ensure a healthy breathing environment.

Description

technical field [0001] The invention belongs to the field of ventilation equipment for underground pipe galleries, and in particular relates to a ventilation and filtering method for logistics in underground pipe galleries. Background technique [0002] The underground comprehensive pipe gallery is a public tunnel built underground in the city for the centralized laying of municipal pipelines such as electricity, communications, radio and television, and water supply; the underground logistics system is an innovative logistics model. The underground logistics system not only has fast, It has the advantages of high accuracy, and is an important and effective way to solve urban traffic congestion, reduce environmental pollution, and improve the accessibility and quality of urban cargo transportation; the underground logistics system can meet the development model of circular economy and meet the development requirements of a resource-saving society. It is a necessary choice fo...
