District cooling and heating transportation and distribution pipe network health check system

Abstract

The invention provides a district cooling and heating transportation and distribution pipe network health check system. The district cooling and heating transportation and distribution pipe network health check system comprises a water distributor, a water collector, water inlet pipelines, water return pipelines, a plurality of filters and a plurality of electrical control valves; the water distributor is connected with a plurality of terminals through the water inlet pipelines, and the water inlet pipeline comprises a plurality of water distribution openings; the water collector is connected with the terminals through the water return pipelines, and the water return pipeline comprises a plurality of water collection openings; the filters are arranged on positions, adjacent to the terminals, of the water return pipelines; the collection unit comprises a plurality of water pressure sensors, the junctions between each water inlet pipeline and the water distributor and between each water inlet pipeline and each terminal, the junctions among each water distribution opening and each water return pipeline and the water collector and the terminal as well as the water collection openings are respectively provided with a water pressure sensor; each filter is arranged between every two adjacent water pressure sensors; the electrical control valves are arranged in the water inlet pipelines and the water return pipelines. A plurality of water pressure sensors are arranged in the pipelines, and whether the pipeline is blocked or not and the blockage position of the pipeline are judged according to the pressure difference detected by the water pressure sensors, so that real-time monitoring of the pipelines can be realized.

Description

[0001] technical field [0002] The invention relates to an inspection system, in particular to a health inspection system for district cooling and heating transmission and distribution pipe networks. Background technique [0003] After a period of operation, the traditional district cooling and heating distribution pipelines usually have increasing water resistance, which will cause problems such as unbalanced water pressure in the system and a sharp increase in energy consumption. The traditional solution is mainly to rely on personal experience or use mechanical instruments to judge whether it is blocked, or to regularly disassemble and clean all easy-to-block points. The biggest disadvantage of this method is that it is likely that the blockage point cannot be found in time and accurately, resulting in processing only when the blockage is relatively serious, and at this time a large energy consumption loss has been caused.
