Embodiment Construction

[0024] The self-operated vacuum drainage system designed by the present invention is as figure 1 As shown, it includes: a sewage tank 1, a vacuum tank 2, a vacuum pump 5, a vacuum boundary valve 10, a drainage pump 3, an air compressor 9, a PC, and multiple control valves. in:

[0025] Sewage tank 1 is a sewage collection point. In actual use, there can be multiple such sewage tanks on site; the sewage tank is usually made of plastic or steel plate, and can also be made of cement and buried. If there are many impurities in the sewage, a trash rack should be added to the sewage tank. A water level sensor is installed in the sewage tank to measure the sewage water level in the sewage tank.

[0026] The vacuum tank 2 is used to store the collected sewage, which is the core of the whole system; the vacuum tank is provided with three interfaces: the vacuum pump interface 14 is used to connect with the vacuum pump group; the sewage pipe interface 15 is used to connect the sewage p...

Abstract

The invention belongs to the field of environmental protection technology, in particular to a self-operated vacuum drainage system. The vacuum drainage system is practically a sewage collecting system which leads to all directions through a pipeline communicated with a vacuum tank, leads to sewage collecting points, and is used for pumping sewage into the vacuum tank through a vacuum pump unit and draining the sewage into a main municipal pipeline through a sewage pump or an air compressor. The system comprises a sewage tank, the vacuum tank, a vacuum pump, a vacuum boundary valve, a drainagepump, the air compressor, a PC (Personal Computer), corresponding control software and the like. Compared with the conventional gravity blowdown system, the self-operated vacuum drainage system has the characteristics of simple construction, low cost, flexible movement and high efficiency. The self-operated vacuum drainage system is mainly used for collecting the sewage of industrial and mining establishments, institutions, schools, city and countryside residential areas and the like, can also be used for collecting excrements in vacuum toilets, contributes to saving a large amount of water, is free from odor by running under negative pressure, is particularly suitable for water-lacking cities, and can also be applied to toilets on subways, trains and long-distance buses.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a self-operated vacuum drainage system and a control method thereof. Background technique [0002] In the construction of China's comprehensive development process, the infrastructure in the field of drainage and sewage is facing huge challenges. The traditional way of transporting rain, sewage and wastewater using gravity has exposed more and more weaknesses and disadvantages. The leakage and discharge of gravity transportation pollute groundwater resources and the environment, which is not conducive to the recycling of reclaimed water, and seriously hinders environmental protection and ecological progress; gravity drainage and sewage need to build gravity lifting pumping stations, construct large-scale excavation projects, and lay large-scale pipe networks , consumes a lot of construction materials, requires a large amount of construction work, long...
