Description

Technical Field

[0001] The utility model relates to the technical field of ion exchange removal preparation equipment, in particular to ion exchange removal continuous preparation equipment with the effect of improving accuracy. Background Art

[0002] Ion exchange devices mainly refer to reactors for ion exchange, and the exchanger filled with exchange agents is also called a bed. There are many types of ion exchange devices, the most common ones are downstream regenerative ion exchangers, countercurrent regenerative ion exchangers, and floating bed ion exchangers.

[0003] The existing ion exchange removal continuous preparation equipment, when performing the ion exchange removal work, uses the filtering component and the forward and reverse flushing component to continuously cycle and flush and exchange the material to exchange and remove the ions in the material. However, in the forward and reverse flushing work, in addition to the necessary filter layer (quartz sand or activated carbon), an exchange agent layer is also provided. During the working process, a large amount of regeneration liquid needs to be added for auxiliary use. However, the regeneration liquid is added through a pipeline, and the pipeline discharge position is fixed, so that the regeneration liquid can only be located on the upper layer of the material, and the lower layer needs to be gradually infiltrated and mixed, which affects the preparation efficiency. Moreover, it is difficult to make the regeneration liquid and the material completely and evenly mixed by relying on the gradual penetration of the regeneration liquid itself, thereby affecting the preparation quality. It is necessary to continuously cycle the preparation multiple times, increase the preparation time, extend the preparation process, and have low efficiency.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an ion exchange removal continuous preparation equipment with improved precision is proposed. Utility Model Content

[0023] Furthermore, the barrier nets (2) are located at the upper and lower sides of the preparation tank 1, so that water can flow normally, but the internal materials cannot pass through, so that a preparation removal cavity is formed in the middle of the preparation tank 1.

[0024] Furthermore, the impeller (4) will rotate when impacted by the forward and reverse wash water flow, thereby driving the rotating rod (3) and the stirring blade (5) to rotate, thereby performing stirring and mixing work.

[0025] Furthermore, the collection tank (6) collects the regeneration liquid and evenly distributes it to each layer of the material using the circulation pipe (7) and the liquid outlet 8 surrounding the bottom, without the need for the regeneration liquid to gradually infiltrate and mix.

[0026] Furthermore, a mesh partition is provided between the quartz sand layer (10) and the exchange agent layer (11) for separation and blocking, and the quartz sand layer (10) and the exchange agent layer (11) can perform mixing treatment on the materials.

[0027] like Figure 1 and Figure 4As shown, a water inlet pipe (12) is fixedly provided at the top of the preparation tank (1), a water outlet pipe (13) is fixedly provided at the bottom of the preparation tank (1), a backwash drain pipe (14) is provided on the right side below the water inlet pipe (12), an exhaust air pipe (15) is fixedly provided on the left side below the water inlet pipe (12), a backwash water inlet pipe (16) is fixedly provided on the right side of the middle of the water outlet pipe (13), a drain port (17) is installed on the right side of the upper end of the water outlet pipe (13), and a forward wash and regeneration liquid drain pipe (18) is installed on the left side of the upper end of the water outlet pipe (13).

[0028] Furthermore, the water inlet pipe (12) and the water outlet pipe (13) are respectively located at the upper and lower ends of the preparation tank 1, and the water inlet pipe (12) and the water outlet pipe (13) can be used as inlet and outlet water pipes to perform forward and reverse washing of the material.

[0029] Furthermore, an air exhaust pipe (15) is located on one side of the water inlet pipe (12) to exhaust the air generated by flushing.

[0030] Furthermore, the water inlet pipe (12) and the water outlet pipe (13) respectively utilize the backwash drain pipe (14), the backwash water inlet pipe (16), the drain port (17) and the forward wash and regeneration liquid drain pipe (18) as the discharge ends of the flushing water and the regeneration liquid sewage, and can also be used as the inlet port of the flushing water.

[0031] Working principle: When using the ion exchange removal continuous preparation equipment with improved accuracy, first, according to the requirements of forward and reverse washing, the backwash drain pipe (14) and the water inlet pipe (12) are selected as the water inlet end for forward washing. At this time, the outlet pipe (13), the backwash inlet pipe (16), the drain port (17) and the forward washing and regeneration liquid drain pipe (18) are all used as the sewage discharge end of the forward washing. On the contrary, the reverse washing uses the backwash inlet pipe (16) as the water inlet end, and the outlet pipe (13) is converted into a conveying pipe body for water intake. The sewage of the reverse washing will flow back. Under intermittent water injection, it is cleaned from bottom to top, and the sewage still keeps falling, and enters through the drain port (17) and the forward washing and regeneration liquid drain pipe (18). The forward and reverse wash can be flexibly switched during discharge. During the forward and reverse wash process of ion exchange removal, the water of the forward and reverse wash will use the impeller (4) to drive the rotating rod (3) to rotate, thereby causing the stirring blade (5) to rotate and stir the material, so that the material and the reaction removal substance are fully combined. At the same time, the regeneration liquid is transported to the collection tank (6) through the regeneration liquid inlet pipe (9), and is evenly distributed between the layers of the stirring blade (5) through the circulation pipe (7) and the liquid outlet (8). The stirring blade (5) further fully mixes the material and the regeneration liquid of each layer, thereby improving the work quality efficiency and uniformity of the ion exchange removal of the material. This is the working principle of the ion exchange removal continuous preparation equipment with improved accuracy.
