Detailed Description

To facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The terms "vertical," "horizontal," "left," "right," "inner," "outer," and the like as used herein are for descriptive purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, a schematic diagram of a sulfur removal system according to an embodiment of the present invention is shown. First, it is worth mentioning that calcium hydroxide is also called hydrated lime and calcium oxide is also called quicklime. The quicklime is added with water to react to generate hydrated lime. In essence, the effective part for removing the sulfate radicals is calcium ions in the hydrated lime, and the calcium ions react with the sulfate radicals to generate calcium sulfate precipitates, thereby removing the sulfate radicals in the wastewater.

Regarding the present sulfur removal system, it comprises a first tank 10, a liquid inlet pipe 20, a second tank 30 and a water pump 40. Wherein, first pond 10 is used for storing the calcium hydrate solution, and inlet channel 20 is used for letting in the waste water of waiting to remove sulphur in first pond 10, and second pond 30 is used for depositing calcium oxide, and water pump 40 is used for carrying the solution in first pond 10 to second pond 30, and the lateral wall in second pond 30 is equipped with the intercommunication mouth 31 with first pond 10 intercommunication for flow the calcium hydrate solution in second pond 30 to first pond 10. It will be appreciated that the second tank 30 is disposed adjacent to the first tank 10, sharing side walls with the first tank 10.

In order to prevent the calcium hydroxide solution in the second tank 30 from flowing out through the communication port 31 and not from the top of the tank wall, the communication port 31 should be set lower than the top of the tank wall of the second tank 30. Similarly, in order to prevent the calcium hydroxide solution flowing out from the communication port 31 from directly flowing out at the wall of the first tank 10, it is reasonable that the height of the communication port 31 is higher than the height of the wall of the first tank 10. Preferably, the first tank 10 and the second tank 30 are of square design.

In order to prevent the external environment from polluting the solution in the first tank 10, the first tank 10 is provided with a top wall 50, and the top wall 50 is also used for facilitating the installation of parts outside the tank body, such as the water pump 40.

As for the water pump 40, it includes a pump 41 and a water pipe 42. It is worth mentioning that, in order to avoid calcium sulfate precipitation or other turbid matters being pumped to the bottom of the first tank 10 from the water inlet end of the water pipe 42, the water inlet end of the water pipe 42 should be 0.5-1m away from the bottom of the first tank 10. In order to prevent the water outlet end of the water pipe 42 from contacting with the quicklime, the water outlet end of the water pipe 42 is 0.3-0.5m away from the bottom of the second tank 30. In addition, a portion of the water tube 42 may be mounted to the upper surface of the top wall 50.

In order to facilitate the dredging of the bottom of the first tank 10 or to remove calcium sulfate sediments, a floor drain 11 is arranged on the bottom wall or the side wall of the first tank 10 close to the bottom wall, and a high-pressure water gun can be used for dredging the bottom of the tank. In addition, the bottom of the first tank 10 should be inclined toward the floor drain 11, and the floor drain 11 should be the lowest bottom of the tank.

The utility model discloses specific embodiment's use: the first pond 10 is stored with calcium hydroxide solution, and the second pond 30 is stored with calcium oxide, and inlet channel 20 lets in waste water to first pond 10, and the sulfate in the waste water reacts with calcium hydroxide solution and produces calcium sulfate and deposits. Along with the inflow of waste water, the calcium ion concentration in first pond 10 reduces gradually, need in time open water pump 40, take out the solution in first pond 10 to the second pond 30 in, the calcium oxide in the second pond 30 meets the water reaction and generates the calcium hydrate solution, and this calcium hydrate solution flows into first pond 10 through intercommunication mouth 31, has supplemented the calcium ion concentration in the first pond 10 for the process of waste water sulphur removal can continue.
