Referring to fig. 1, an air conditioner water system impurity removing device includes: an impurity settling chamber 1; the water inlet 5 is communicated with the impurity settling chamber 1; the water outlet 7 is arranged above the water inlet 5 and is communicated with the top of the impurity settling chamber 1; the impurity settling chamber 1 is vertically arranged in a cylindrical shape, and the diameter D1 of the cross section of the water inlet 5 and the diameter D2 of the cross section of the impurity settling chamber 1 meet the requirement that D2> D1.

Use the utility model discloses an air conditioner water system edulcoration device, when using, the circulating water with impurity gets into impurity settling chamber 1 from water inlet 5, because the cross-sectional diameter D2 of impurity settling chamber 1 is greater than the cross-sectional diameter D1 of water inlet 5, the circulating water gets into behind the impurity settling chamber 1, velocity of flow greatly reduced, the thrust that impurity obtained from the aquatic this moment is less than the gravity of impurity self, consequently most impurity can deposit impurity settling chamber 1 bottom under the action of gravity, then the water after impurity subsides rises, and discharge along the delivery port 7 at top, thereby reduce the jam to the pipeline, because need not to set up the filter screen in the whole edulcoration device inner chamber, what rivers received blocks lessly, flow loss is less.

Wherein, flanges can be arranged on the water inlet 5 and the water outlet 7, which is convenient for butt joint with pipelines.

Furthermore, the top end of the impurity settling chamber 1 is communicated with a rectification chamber 6, the rectification chamber 6 is communicated with the impurity settling chamber 1 and a water outlet 7, and the diameter of the cross section of the water outlet 7 is equal to the diameter D1 of the cross section of the water inlet 5; when water flow rises along the impurity settling chamber 1, the water flow is rectified by the rectifying chamber 6, the flow section is reduced to the section of the water outlet 7, the flow speed is increased, and the diameters of the sections of the water inlet and the water outlet 7 are equal, so that the water flow can be further accelerated and even restored to the original flow speed, and the flow loss is further reduced.

In order to reduce the impact of the circulating water on the rectification cavity 6 and reduce noise, the inner wall surface of the rectification cavity 6 is a spherical surface.

In order to collect impurities in the impurity settling chamber 1 without stopping the machine and avoid silting of the impurity settling chamber 1, an impurity collecting chamber 2 is communicated below the impurity settling chamber 1, and an impurity discharge pipe 3 is communicated below the impurity collecting chamber 2; at the moment, the circulating water can be discharged along the water outlet 7 at the upper part, and impurities are accumulated in the impurity collecting cavity 2 at the lower part and are discharged along the impurity discharge pipe 3; the water pressure of the circulating water also promotes the discharge of impurities from the discharge pipe, thus reducing silting.

As shown in fig. 1, the impurity collecting chamber 2 may be provided in an isosceles triangle section, and the triangle base angle may be set to 30 to 70 °.

Further, a blow-off valve 4 is arranged on the impurity discharge pipe 3, and the blow-off valve 4 is used for opening or closing the impurity discharge pipe 3; when impurity does not need to be discharged, the blow-down valve 4 can be closed, the circulating water is prevented from excessively flowing and losing from the impurity discharge pipe 3, and the blow-down valve 4 can be opened for blow-down after a certain amount of impurities are accumulated in the impurity collection cavity 2.
