Abstract

The invention provides a waste water draining system which comprises a drain pipe system, wherein the drain pipe system comprises an inner pipe, an outer pipe and a bracket; the inner pipe is used forconveying and draining waste water or spent liquor; the outer pipe is mounted outside the inner pipe in a sleeving manner and is used for receiving leakage waste water flowing out when the inner pipeleaks; the bracket is arranged in the outer pipe and is used for supporting the inner pipe; after the inner pipe is supported and hung by the bracket, a leakage solution passageway allowing leakage waste water to flow smoothly is formed in the outer pipe and below the inner pipe. The waste water draining system is simple in structure and convenient to construct, can timely find the leakage problem, can ensure the life safety of a maintainer and also has the advantages of being flexible in design and low in cost.

Description

technical field

[0001] The invention relates to the technical field of industrial waste water drainage, in particular to a waste water discharge system. Background technique

[0002] Due to the particularity of production projects in the aerospace field, production wastewater often contains toxic and harmful substances such as strong acids, strong alkalis, heavy metals, and cyanides. At present, people's attention is focused on the collection, treatment and recycling of production wastewater, but the special practice of toxic and harmful production wastewater outdoor pipelines is ignored. Once the outdoor pipeline corrodes and leaks, it will seriously endanger the ecological environment and human health. Contents of the invention

[0003] The object of the present invention is to provide a wastewater discharge system to solve at least one of the above-mentioned technical problems in the prior art.

[0004] In order to solve the above technical problems, the present inven...
