An automatic dehumidification system for underground comprehensive utility gallery

Abstract

The invention discloses an automatic dehumidification system for an underground comprehensive pipe gallery, which includes a pipeline, the surface of which is coated with a layer of anti-rust paint, and the outer surface of the waterproof paint layer of the pipeline is also covered with a water-absorbing coat, and the water-absorbing coat includes The cross-section of the fixed sleeve is arc-shaped. The inner surface of the fixed sleeve is smooth and is set on the surface of the waterproof paint layer of the pipeline. The outer surface of the fixed sleeve is covered with a water-blocking layer. structure, the two sides of the notch of the fixed sleeve are detachably connected with a water guide plate, the bottom side of the water guide plate is inclined, and the bottom side of the water guide plate is turned outwards and upwards to form a water guide groove, and the lower end of the water guide groove is connected by a hose. A water delivery pipe, the water delivery pipe is laid in the pipe gallery and located below the pipeline. The invention realizes the heat exchange of the hot and humid air entering by adding a fixed sleeve on the original pipeline, making it cool down and transforming it into water droplets, and discharges the water droplets out of the pipe gallery to complete the dehumidification work in the pipe gallery, and its dehumidification effect Good, and low cost of dehumidification.

Description

technical field [0001] The invention belongs to the technical field of pipe gallery dehumidification, and in particular relates to an automatic dehumidification system for an underground comprehensive pipe gallery. Background technique [0002] The underground comprehensive pipe gallery is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, and implementing unified planning , Unified design, unified construction and management. In an underground pipe gallery, electricity, communication, gas, heating, water supply, and drainage are separated by partitions and divided into various functional partitions. Among them, the functional partition space for water supply and drainage is the largest, because both water supply and drainage are cold water and the pipe gallery is located underground, there...

Problems solved by technology

This method simply prevents water from contacting the pipeline and the surface of the corridor wall, and does not play a role in dehumidification. It also needs to set up a large number of dedicated dehumidification equipment separately, which increases the construction cost and operation and maintenance cost of the pipeline corridor.
