Double-flow pipe

Abstract

The invention relates to a double-flow pipe capable of simultaneously conveying two fluids which are not confused. A dividing wall is arranged in a pipe cavity, wherein the length and width of the dividing wall are equivalent to those of a pipe, and the two sides of the dividing wall are connected with the wall of the pipe, so that a pipe with two semi-circle cavities (channels A and B) is formed. As required, double-flow pipes in different specifications are paved into a double-flow water supply pipeline and a double-flow sewage draining pipeline ('double supply' and 'double drainage' for short), firstly running water is delivered to water used household by virtue of the channel A of the 'double supply', and reclaimed water is delivered to the water used household by virtue of the channel B of the 'double supply', secondly, manure water produced by the reclaimed water when flushing the toilet is delivered to a manure water treatment workshop by virtue of the channel B of the 'double drainage', and electric energy, fuel gas and organic fertilizer are produced; and sewage produced by the running water and reclaimed water after use flows to a sewage treatment workshop by virtue of the channel A of the 'double drainage', and the produced reclaimed water is injected to the channel B of the 'double supply', so as to be delivered to the water used household; and thirdly the process is repeated, thus realizing recycling.

Description

1. Technical field [0001] The invention relates to a pipe for transporting fluid, in particular to a double-flow pipe which can pass two kinds of fluids simultaneously without being confused with each other. 2. Background technology [0002] As we all know, my country is a country seriously short of water, and the waste of water resources is serious - a large amount of sewage, especially domestic water, is not recycled and used in vain, and the utilization rate of recycled and purified reclaimed water is also very low. What is more regrettable It is a valuable organic fertilizer raw material - human feces water (hereinafter referred to as "dung water"), which not only becomes one of the main pollution sources of sewage, but also requires great efforts to purify it, and so on. [0003] The existing urban water supply system and sewage system are all constructed with circular single-flow pipes (only one circular cavity). One pipe cannot accommodate two kinds of water flow at th...

Problems solved by technology

[0003] The existing urban water supply system and sewage system are all constructed with circular single-flow pipes (only one circular cavity). One pipe cannot accommodate two kinds of water flow at the same time, otherwise it will "confluent with sewage" and merge into one, which cannot solve the problem Two major problems of "wide use" of water and "recycling" of manure

If two more pipelines are added to transport reclaimed water and recovered fecal water respectively, the investment, construction cost and workload will inevitably be greatly increased, and the pipelines will take up a lot of space, which is neither simple nor convenient, and it is difficult to push them apart in practice.
