Description

Residential building water recycling system

technical field

The utility model relates to a water recycling system, in particular to a domestic domestic water recycling system.

Background technique

At present, the industrial water recycling technology is very mature and widely used in all walks of life. However, industrial water recycling requires a large investment in facility construction, relatively complex technology, a large amount of water to be treated, high cost of consumables, and a long treatment cycle during the treatment process, which is not suitable for the recycling of domestic domestic water. The recycling of domestic water for residents is mainly to store lightly polluted domestic water through some equipment and devices, or store it for use through some simple filtration. However, the existing technology and devices have a high degree of decentralization and are limited to each household. The reclaimed water cannot be distributed reasonably, and the utilization efficiency of the reclaimed water is not high, resulting in insufficient reclaimed water for some users and wasted reclaimed water for some users. Most of the existing technologies and devices have the problems of complicated filter devices or high replacement cost of filter elements, or inconvenient cleaning of filter devices. Most of the existing technologies and devices need to be driven by electric pumps. During the utilization of circulating water, a large amount of electric energy is consumed, and it is impossible to meet the requirements of energy saving while saving water.

Currently published related patents mainly include:

1. Ma Mingyi, Haidian District, Beijing, "Sewage Circulation Treatment Equipment for Kitchen, Bathroom and Bath", Patent No. 02289455.1

2. "A household bath wastewater treatment and recycling system" by Li Bing, Haidian District, Beijing, patent number 200320102577.0

3. "Household Wastewater Recycling Centralized Treatment Equipment" by Wenrong, Zhuhai City, Guangdong Province, application publication number CN 101781903A

4. "Residential Building Wastewater Reuse Water Tank" by Zhang Bin, Taiyuan City, Shanxi Province, Patent No. 200520024191.1

Most of the reuse systems involved in the above-mentioned patents need to use electric pumps, which can save some water resources but cause consumption of electric energy, which cannot meet the requirements of energy saving. Most of the residential water reuse systems and devices involved in the above-mentioned patents are used in a decentralized manner, which is limited to each household, resulting in high investment costs, inability to rationally distribute reclaimed water, and low efficiency of domestic water use, resulting in huge waste. Most of the above-mentioned patents are self-production and utilization by a single user. There is no metering equipment, and the water-saving effect cannot be quantitatively analyzed, which is not conducive to the promotion of water-saving. To sum up, at present, it is necessary to seek a centralized and comprehensive water recycling system that does not need to be driven by an electric pump, can distribute recycled water reasonably, can count the amount of recycled water, and can effectively improve water utilization efficiency.

The junction of the primary filter device 3 and the heavy sewage pipeline 7-2 is provided with a filter sewage valve 3-4. Since the filter sewage valve 3-4 is installed below the primary filter device 3, for the convenience of the filter sewage valve 3-4 control, Filter sewage valve 3-4 adopts electric control valve. According to the degree of cleanliness of the primary filter device 3, the filter screen 3-1 is cleaned regularly. Cleaning water comes from tap water, and for the convenience of recoil cleaning valve 3-3 control, recoil cleaning valve 3-3 is installed above the floor. the

The secondary filter adopts a filter device composed of replaceable PP filter element and activated carbon filter element. The PP filter element can remove insoluble impurities and some colloidal impurities in the water to reduce the SDI value of the water, and the activated carbon filter element can remove residual chlorine and chloride in the water and remove odors.

3. Water storage and supply part

The main function of the water storage and water supply part is to store the finely filtered water for the downstairs users, and realize the reasonable distribution of water through the pressure-limiting water storage valve, and use the excess water for community greening and car washing, etc., where recycled water can be used field. The water storage and supply part is mainly composed of a water storage tank 5, a water inlet meter 8-2, a water supply meter 8-1, a water storage and discharge valve 5-1, a pressure limiting water storage valve 6 and other valves.

The water supply measuring water meter 8-1 is installed on the pipeline that the user supplies water to the water storage tank 5, that is, after the secondary fine filtration. The water supply meter 8-1 is used to count the amount of water supplied by the user to the regenerated water of the entire system. The water inlet metering meter 8-2 is installed on the water storage tank 5 to the user's water supply pipeline 7-3 downstairs. The water metering water meter 8-2 is used to count the water consumption of the user from the whole system. The water supply meter 8-1 and the water inlet meter 8-2 comprehensively count the amount of water supplied or taken by the user for the regenerated water of the system. Based on the user's tap water consumption and the user's reclaimed water supply (or water intake), the user's water consumption is charged. This quantitative statistical billing method is beneficial to the promotion of the concept of water saving and energy saving.

The water after secondary fine filtration is connected to the upper part of the water storage tank through a pipeline. Three water pipes are equipped with at the bottom of the water storage tank 5, one is used as the water pipe for supplying water to the user on the next floor, one is used as the water supply pipe 7-4 of the next water storage tank for the last water storage tank, and one is used as the water storage pipe for the water storage tank. The water blowdown valve 5-1 is convenient for the regular blowdown cleaning of the water storage tank 5.

The pressure-limiting water storage valve 6 is installed on the water supply channel of the previous water storage tank 5 to the next water storage tank. The regenerated water in the water flows to the next water storage tank, and when the water level in the last water storage tank 5 is lower than a certain limit value, the pressure-limiting water storage valve 6 is automatically closed.

This water recycling system installed in a complete set is only connected to the roof drain pipe on the uppermost floor, which can make the system simpler and reduce investment. After the bottom water tank of this water recycling system is full of water, the excess water is led to the green irrigation pool of the community or to other places that need water such as car wash shops around the community through the pipeline where the water storage pressure limiting valve is located. This water recycling system is also a convenient reclaimed water manufacturing and sales network, which can greatly improve water utilization efficiency.
