In order to facilitate monitoring of the concentration of chloride ions in the cooling liquid, a chloride ion concentration sensor 8 electrically connected with the controller 10 is further arranged in the liquid outlet pipe 3
Considering that the purifying assembly 4 may be blocked, a first flow sensor 5 and a second flow sensor 7 electrically connected to the controller 10 are respectively disposed at two ends of the purifying assembly 4 in the liquid outlet pipe 3.
The bypass channel structure is mainly designed by determining the size of the cross section of the bypass channel, and the size of the cross section of the bypass channel is designed based on comprehensive fluid mechanics analysis, which specifically comprises the following steps:
the turbulence model adopts a standard occupation turbulence model, and a turbulence kinetic energy equation and a diffusion equation are shown as a formula (1) and a formula (2):
in formula (1): Δ t w Δ t is the change in temperature of the coolant as it circulates during engine operation w In the range of 6 ℃ to 12 ℃ and at w ＝10℃；γ w Is the density of water, generally gamma w ＝1000Kg/m 3 ；C w Is the specific heat of water, in KJ/Kg. ℃, in general C w ＝4.187
1 actual cooling water circulation volume
The formula is as follows:
V a ＝1.2 V w ＝1.2×0.00196＝0.002352m 3 s type (2)
Since each phase is considered to be an interpenetrating continuum in the euler model, a volume fraction is required to represent the space occupied by each phase in the control volume.
The volume occupied by phase q is defined as:
wherein the sum of all phase volume fractions is 1:
therefore, the effective density of the q-th phase in the control body is converted into:
similarly, using Newton's second law, the change in momentum of the q-th phase in the control volume is written: the rate of change of momentum with time + the amount of change in momentum caused by the fluid passing over the surface of the control body-the force applied to that phase in the control body.
According to the design principle of the bypass channel and the comprehensive analysis of fluid mechanics, when the area of the bypass channel is designed to be one-half of the sectional area of the pipeline, the circulation of a cooling system cannot be influenced when the fluid is ensured to effectively pass through.
The material of the ion exchange resin layer 4-4 is D201 resin. The resin has the advantages of small influence of temperature, stable chemical property, high mechanical strength, high anti-pollution capacity, high repeated utilization rate and the like, and is suitable for being used in severe environment, so that the D201 type resin is selected from the ion exchange resin layers 4-4.
In addition, when the D201 resin is not used for adsorbing chloride ions after the adsorption task is finished, the regeneration of the resin is needed. The regeneration of the ion exchange resin is a complex process, and the regeneration concentration, flow rate, time and the like influence the regeneration effect, so that the ion exchange resin device can be disassembled, and then the regeneration of the resin is completed in an external special device. Therefore, the regeneration process of the resin can be simplified by replacing the ion resin device, and the recycling of the resin is realized. Meanwhile, in order to improve the transformation rate of the D201 resin, the resin can be treated by sulfuric acid in the links of pretreatment, desorption and the like. The reference literature shows that the regeneration rate of the resin can reach about 90%.

The cooling liquid mainly comprises glycol and water, wherein the content of the cooling liquid is 30-70%.
It should be noted that when the concentration of the chlorine ions is too high or the flow rates of the first flow sensor 5 and the second flow sensor 7 are not consistent or the PH value deviates from the set threshold range, the alarm on the controller 10 will give an alarm.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
