Description

Technical Field

[0001] The invention relates to the technical field of aluminum sulfate cooling, and in particular to adjustable multi-stage cooling equipment. Background Art

[0002] In the field of water treatment agents, liquid aluminum sulfate, as an important inorganic polymer flocculant, is widely used in multiple links such as drinking water purification, industrial wastewater treatment, and sewage treatment; however, the production process of liquid aluminum sulfate involves a series of complex chemical reactions and physical changes, among which the cooling link plays a vital role in product quality and production efficiency.

[0003] At present, cooling through pipeline transportation is a crucial link in the production process of liquid aluminum sulfate; however, in actual operation, due to the limitations of the internal structure of the pipeline and the limitations of the heat exchange method between the cooling medium and the material, the liquid aluminum sulfate in the center of the pipeline is often difficult to be fully cooled; specifically, when liquid aluminum sulfate flows in the pipeline, the material close to the pipeline wall is in direct contact with the cooling medium (such as cooling water or cooling air), and can lose heat more quickly, and the temperature is effectively reduced; while the liquid aluminum sulfate located in the center area of the pipeline, due to the wrapping of the surrounding materials and the difficulty of direct contact with the cooling medium, its heat dissipation rate is significantly slower, resulting in a relatively high temperature of the liquid aluminum sulfate in this area and poor cooling effect; this uneven cooling phenomenon not only affects the overall cooling efficiency of the liquid aluminum sulfate, but may also have an adverse effect on product quality; and traditional cooling methods mostly adopt a single-stage cooling structure, and the heat exchange area between the cooling medium and the material is limited, resulting in slow cooling speed and low efficiency.

[0014] Beneficial effects 1.

[0015] 2. The present invention, by providing a fan and a heat dissipation cylinder, can further cool the coolant that has completed the primary cooling task, so that the cooled coolant enters the second cooling cylinder and further cools the liquid aluminum sulfate in the cooling tube B; it is beneficial to use the same group of coolants to perform multi-stage cooling of the liquid aluminum sulfate; and furthermore, the same group of cooling media can be sequentially passed through the multi-stage cooling units to form an energy utilization system for gradient cooling.

[0016] 3. The present invention forms a honeycomb structure of the heat dissipation cylinder by providing three layers of heat dissipation cylinders, thereby enabling the coolant entering the transition frame to adhere to the outer wall of the heat dissipation cylinder for multiple times for diversion; increasing the contact area between the coolant and the heat dissipation cylinder; and thus facilitating the re-cooling of the coolant that has completed the primary cooling task; thus laying the foundation for multi-stage cooling of liquid aluminum sulfate.

This design achieves dynamic matching of the conveying rate of liquid aluminum sulfate by adjusting the rotation speed of the spiral conveying roller; specifically, when the spiral conveying roller rotates at a specific angular velocity, the axial thrust and radial shear force generated by its spiral blades on the liquid aluminum sulfate work together, which can not only prevent the liquid aluminum sulfate from laminar stagnation or eddy current aggregation in the tube, but also can accurately control the residence time and temperature gradient distribution of the liquid aluminum sulfate in the cooling tube B through the quantitative relationship between the flow rate and the heat transfer coefficient, and can better control the final temperature of the liquid aluminum sulfate after cooling.
