Air-hose-free ventilation system applicable to underground type water treatment structure

Abstract

The invention discloses an air-hose-free ventilation system applicable to an underground type water treatment structure. The system comprises a ventilation target area, an air supply gallery, an air feeding unit and an air exhaust unit, wherein the start end of the ventilation target area communicates with the air supply gallery, the tail end of the ventilation target area is provided with the exhaust unit, the air supply gallery is arranged on one side of the ventilation target area, the side, facing the ventilation target area, of the air supply gallery is provided with an outlet adjusting louver, the air feeding unit comprises an air feeding channel, an air supply blower is arranged in the air feeding channel, the air feeding channel communicates with the outdoor space through an air supply well, the air exhaust unit comprises an exhaust fan and an exhaust well located above the exhaust fan, and the exhaust unit is used for exhausting air in the ventilation target area. Air-hose-free ventilation system arrangement in the target ventilation area is achieved, attractiveness is achieved, meanwhile, the burial depth of an underground type sewage treatment plant is reduced, and initial investment in civil engineering is reduced; the air age and pollutant concentration in a large-space internal inspection area is reduced, and ventilation efficiency and pollution discharge efficiency are improved.

Description

technical field

[0001] The invention relates to the field of water treatment, in particular to a ductless ventilation system suitable for underground water treatment structures. Background technique

[0002] The underground water treatment structure transfers the water treatment facilities from the open air to the underground. It has the advantages of strong sealing, environmental friendliness, small footprint, can improve the quality of surrounding plots, and has the advantages of organic combination with greening and water features and good aesthetics. It has been favored by local governments. With the approval of surrounding residents, the demand for construction has increased sharply, and it has become a new direction for urban water treatment engineering construction.

[0003] Underground water treatment structures are generally divided into three layers: the ground layer usually includes a number of ventilation shafts, entrances and exits, etc., and most of the rest ar...

Examples

Embodiment

[0024] Embodiment: This embodiment specifically relates to a ductless ventilation system for underground water treatment structures, which has high ventilation efficiency and sewage discharge efficiency, low air age, less ventilation stagnation areas, and good uniformity of air supply and exhaust. The advantages of low operating energy consumption and low noise can effectively reduce the overall buried depth of underground water treatment structures, reduce the pressure head of fans, and save initial investment in project construction and operation and maintenance costs.

[0025] Such as image 3 As shown, the ductless ventilation system of an underground water treatment structure consists of an air intake unit, an air supply corridor, a ventilation target area, and an exhaust unit.

[0026] The air intake unit includes: air blower 1, spring shock absorber 2, array muffler 3, electric control valve 4, muffler and rainproof louvers 5, air intake channel 10, air well 11, deflect...
