Embodiment Construction

[0026] see figure 1 , the present invention first injects raw water (tap water) into a water tank for forced internal circulation, and simultaneously presses the raw water in the water tank into an outer circulation filter circuit connected to the water tank for external circulation filtration, and the filtered drinking water is sent back In addition, the water tank also needs to regularly perform reverse cleaning on the circulating filter circuit.

[0027] see Figure 2 to Figure 4 , the device that the present invention adopts comprises water tank 1 and the water pump 2 that is connected in series with it, switching valve 3, filtering device 4 and controller 5, wherein water pump 2, switching valve 3 and filtering device 4 have constituted the external circulation filtering circuit, switching valve 3 is used to switch between the normal purified circulating water flow and the reverse cleaning water flow; the two ends of the external circulation filter circuit are respective...

Abstract

A handling method of inner-outsid loop drinking water, first immitting raw water in a water tank and carrying through forced internal circulation of raw water in water tank, at one time press-in a connected with this water tank. This invention adopts the principle of running water non-corroding, making the raw water in water tank pushed to the spray pipe in water tank ceaselessly from the water pump of output circulation loop, and from this spraying water with single direction and polyangle to water tank bottom flat surface, forming inner loop in water tank, realzing agitation and up-down convected circulation. Moreover, raw water carrying through cyclic filtering by outside circulation filtration loop, becoming drinking water after filtering and then reflowing to water tank for users' use. Because using new technique above, putting an end to the waste of water resource, decreasing the use-cost greatly, structural bulk and accommodation area are less, not change the old gas transmission line, more advantaged to the alteration of old supply pipeline.

Description

technical field [0001] The invention relates to an internal and external circulation drinking water treatment method, which is mainly used for purifying tap water raw water to meet drinking water standards. It can be widely used in residential quarters, schools, office buildings, hotels, medical departments, food processing industries, swimming pools, bathing pools and other industries. Background technique [0002] The treatment of existing domestic and drinking water is mainly processed by the waterworks and then enters the municipal water pipeline to be transported to the access ports of various residential quarters or buildings, and then the residential quarters or buildings provide secondary water supply to users, and the secondary water supply Most of the water is stored in the water tank and then supplied to the end user, which causes the pollution of the secondary water supply. In order to solve the pollution problem of secondary water supply, water supply technolog...
