Problems solved by technology
Although the existing cooling towers can meet the requirements of use to a certain extent, because the cooling medium is filled in the entire cooling medium cavity, its circulation velocity is relatively slow, and the temperature of the cooling medium in different regions of the cooling medium cavity is also different. Causes uneven cooling
In addition, when the fluid substance to be cooled is a gaseous substance or liquid substance with a high flow rate, the set cooling effect cannot be achieved due to the short contact time between the fluid substance to be cooled and the cooling medium

The invention discloses a second-step reaction system for efficiently producing polyaluminium chloride. The system comprises a regulating tank, a transit tank of the regulating tank, a cooling tower, a separation tank, a separation slag storage tank, a flocculant preparation tank and a semi-finished product tank. The regulating tank is provided with a calcium aluminate charging hole and a first-step liquid charging hole, and is communicated with the transit tank of the regulating tank. The transit tank of the regulating tank is communicated with an inlet of the cooling tower through a regulating liquid conveying pump. An outlet of the cooling tower is communicated with the separation tank. The flocculant preparation tank is communicated with the separation tank. The upper part of the separation tank is communicated with the semi-finished product tank, and the lower part of the separation tank is communicated with the separation slag storage tank. The system can effectively control and reduce the content of insoluble matters in a reaction solution by separating the insoluble matters produced in polymerization reactions through coagulating sedimentation and settling separation, thus increasing the yield and improving quality of a polyaluminium chloride product. Through adopting a cooling pipe and a cooling medium pipe, the cooling efficiency can be effectively increased, and therefore the second-step reaction efficiency is further increased.
