Detailed Description
The accompanying drawings illustrate embodiments of the present disclosure and it is to be understood that the disclosed embodiments are merely examples of the disclosure, which can be embodied in various forms, and therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.
Referring to fig. 1, a cadmium chloride mixed crystal hydrate solution production system 100 includes a cadmium chloride solution preparation unit 1, a cadmium chloride crystal hydrate mixing unit 2, and a filling unit 3.
The cadmium chloride solution preparation part 1 is used for directly preparing a cadmium chloride solution by adopting water, HCl and cadmium oxide together in situ. The cadmium chloride crystal hydrate mixing section 2 is for mixing the crystal hydrate with the cadmium chloride solution prepared by the cadmium chloride solution preparing section 1 to form a cadmium chloride mixed crystal hydrate solution. The filling part 3 is used for filling the cadmium chloride mixed crystal hydrate solution formed by the cadmium chloride crystal hydrate mixing part 2.
Compared with the method that cadmium chloride is prepared firstly and then the aqueous solution of cadmium chloride is prepared by cadmium chloride and water, in the preparation part 1 of the solution of cadmium chloride, cadmium chloride is formed by the reaction of HCl and cadmium oxide, and then the solution of cadmium chloride is formed by the cadmium chloride in situ and the water, so that the process steps and related equipment are saved, and the production cost is reduced.
In the cadmium chloride mixed crystal hydrate solution production system 100, the automation degree of the preparation of the cadmium chloride mixed crystal hydrate solution is improved by the arrangement of the cadmium chloride solution preparation part 1, the cadmium chloride crystal hydrate mixing part 2 and the filling part 3.
As shown in fig. 1, in one example, the cadmium chloride solution preparing part 1 includes a water supply line 11, an HCl supply line 12, a cadmium oxide supply line 13, and a reaction tank 14.
The water supply line 11 is used for supplying water into the reaction kettle 14; an HCl supply line 12 is used for supplying HCl solution into the reaction kettle 14; a cadmium oxide supply line 13 for supplying cadmium oxide into the reaction vessel 14; the reaction vessel 14 is used for reacting the cadmium oxide and HCl fed therein to form cadmium chloride and the formed cadmium chloride and water to form a cadmium chloride solution.
Referring to fig. 1, in one embodiment, the water supply line 11 includes a water supply pipe 111, a water supply pump 112, a water supply flow meter 113, and a water supply solenoid valve 114. The water supply line 111 is connected between the water supply pump 112 and the reaction tank 14. The water supply pump 112 pumps external water to the reaction tank 14 through the water supply line 111. The water supply flow meter 113 is provided in the water supply pipe 111, and the water supply flow meter 113 measures the flow rate of water in the water supply pipe 111. A water supply solenoid valve 114 is provided in the water supply line 111, and the water supply solenoid valve 114 adjusts the flow rate of water in the water supply line 111.
The water supply pump 112 may be a stainless steel pure water pump.
The positional relationship between the water supply flow meter 113 and the water supply solenoid valve 114 on the water supply line 111 upstream and downstream is not limited, and it is preferable that the water supply flow meter 113 is located upstream of the water supply solenoid valve 114 as shown in fig. 1. The water is fed through the water supply flow meter 113 and then through the water supply solenoid valve 114, which is advantageous for the accuracy of water supply, and the water supply flow meter 113 measures the flow rate of water in the water supply line 111 (i.e., the amount of water delivered), and when the amount of water delivered reaches a predetermined value (for example, when the water is communicated to a PLC control operation station described later), the water supply solenoid valve 114 is immediately closed to stop the water delivery (for example, by the PLC control operation station described later).
Referring to fig. 1, in one embodiment, the HCl supply line 12 includes an HCl storage tank 121, an HCl supply line 122, an HCl supply pump 123, an HCl supply flow meter 124, and an HCl supply solenoid 125. The HCl storage tank 121 stores HCl solution; an HCl supply line 122 is connected between the HCl storage tank 121 and the reaction tank 14; an HCl supply pump 123 is provided on the HCl supply line 122, and the HCl supply pump 123 is configured to pump the HCl solution in the HCl storage tank 121 to the reaction tank 14 through the HCl supply line 122; an HCl supply flow rate meter 124 provided in the HCl supply line 122, the HCl supply flow rate meter 124 measuring a flow rate of the HCl solution in the HCl supply line 122; the HCl supply solenoid valve 125 is provided in the HCl supply line 122, and the HCl supply solenoid valve 125 adjusts the flow rate of the HCl solution in the HCl supply line 122. In the present disclosure, the HCl solution in HCl storage tank 121 is an analytically pure hydrochloric acid solution. In order to prevent the hydrochloric acid corrosion, a perfluoro pump is used as the HCl supply pump 123.
Referring to fig. 1, in one embodiment, the cadmium oxide feed line 13 includes a screw conveyor 131. The screw conveyor 131 is used to supply cadmium oxide powder to the reaction tank 14.
Referring to fig. 1, in one embodiment, reaction vessel 14 includes a vessel body 141. The kettle body 141 is communicated with a water supply line 11, an HCl supply line 12 and a cadmium oxide supply line 13.
Referring to fig. 1, in one embodiment, reaction vessel 14 further includes jacket 142. The jacket 142 is sleeved on the periphery of the reaction kettle 14, and the jacket 142 is used for being communicated with external circulating cooling water to cool the kettle body 141. This is because cadmium chloride formed by the reaction of cadmium oxide and hydrogen chloride in the reaction vessel 14 is an exothermic reaction, and the temperature of the reaction vessel 14 needs to be lowered by circulating cooling water from the outside because the temperature of the reaction vessel is not lowered by only water for forming a cadmium chloride solution.
Correspondingly, reaction vessel 14 also includes a condenser 143. The condenser 143 is disposed on the kettle body 141, and the condenser 143 is configured to condense and converge water vapor formed during the reaction process of the cadmium oxide and the hydrogen chloride into the reaction kettle 14, so as to prevent the water vapor from taking away a part of the solution, thereby preventing the amount of the formed cadmium chloride solution from being affected. As shown in fig. 1, the condenser 143 has a cylinder 143a and a condensing coil 143 b. One end of the cylinder 143a is connected to the inside of the kettle 141, and the other end of the cylinder 143a can be opened and closed under control, preferably, the other end of the cylinder 143a is closed during the whole production process, so as to ensure that no cadmium chloride solution is brought out because the steam is discharged to the environment. The cylinder 143a may be a glass tube. The condenser coil 143b is fed with circulating cooling water.
As shown in fig. 1, in one example, reaction vessel 14 further includes an agitation mechanism 144. The stirring mechanism 144 is used for stirring the raw materials and the products of the reaction kettle 14 which generate the cadmium chloride solution. Thereby, the reaction process of the cadmium oxide and the hydrogen chloride is accelerated, and the uniformity of the formed cadmium chloride solution is accelerated.
As shown in fig. 1, since cadmium chloride is an exothermic reaction formed by the reaction of cadmium oxide and hydrogen chloride, the reaction vessel 14 further includes an integrated temperature transmitter 145 for monitoring the temperature. The integrated temperature transmitter 145 penetrates the kettle body 141, and the integrated temperature transmitter 145 is used for detecting the temperature of the reactant in the kettle body 141 when the cadmium chloride solution is generated. Based on the monitored temperature, the temperature of the reaction kettle 14 is controlled within a predetermined temperature range by correspondingly controlling the jacket 142 to introduce the circulating cooling water to cool the reaction kettle 14 and further cooling the cadmium chloride solution. The integrated temperature transmitter 145 can realize high-reliability and high-precision temperature detection, and is favorable for precise control of the temperature of the reaction kettle 14.
Compared with the prior art in which cadmium chloride is prepared first and then cadmium chloride and water are prepared, in the cadmium chloride mixed crystal hydrate solution production system 100, the cadmium chloride solution preparation part 1 directly adopts water, HCl and cadmium oxide to prepare the cadmium chloride solution in situ (specifically in the kettle body 141 of the reaction kettle 14), thereby simplifying the process and related equipment and reducing the cost.
In order to further improve the preparation accuracy of the cadmium chloride solution, as shown in fig. 1, in one example, the cadmium chloride solution preparation unit 1 further includes a first detection module 15 and a constant volume stirring tank 16.
The first detection module 15 includes a first pump 151, a first filter 152, and a first sampling line 153. The inlet 151a of the first pump 151 is in controlled communication with the bottom outlet 146 of the reaction tank 14, and the outlet 151b of the first pump 151 is in controlled communication with the reaction tank 14. The inlet 152a of the first filter 152 is controlled to communicate with the outlet 151b of the first pump 151. The first sampling line 153 is in controlled communication with the outlet 152b of the first filter 152, and the first sampling line 153 is used for performing pH and specific gravity sampling detection on the cadmium chloride solution formed in the reaction kettle 14 through the first filter 152, the first pump 151 and the reaction kettle 14 which are in communication with each other. The constant volume agitator tank 16 is in controlled communication with the outlet 152b of the first filter 152. Likewise, in one example, the first pump 151 employs a perfluorinated pump to avoid corrosion by hydrogen chloride.
In operation, if the pH value detected by sampling is lower, the amount of cadmium oxide powder needs to be added to raise the pH value, namely, the cadmium oxide supply line 13 increases the amount of cadmium oxide powder needed to be added; if the pH value of the sampling test is too high, the amount of the hydrogen chloride solution needs to be increased to lower the pH value, that is, the HCl supply line 12 increases the amount of the hydrogen chloride solution needed to be increased (specifically, by the HCl supply flow meter 124); if the specific gravity of the cadmium chloride solution sampled and detected is low, the amount of cadmium oxide powder needs to be added to increase the specific gravity, namely the cadmium oxide supply line 13 increases the amount of cadmium oxide powder needed to be added; if the specific gravity of the cadmium chloride solution sampled for detection is too high, the amount of the hydrogen chloride solution needs to be increased to lower the specific gravity, i.e., the HCl supply line 12 increases the amount of the hydrogen chloride solution needed to be increased (specifically, by the HCl supply flow meter 124). Further, for pH value low/high and specific gravity low/high (both of these cases are not qualified) detected by sampling, the outlet 151b of the first pump 151 is connected to the reaction vessel 14 and disconnected from the constant volume stirring tank 16, the cadmium chloride solution formed in the reaction vessel 14 is pumped back into the reaction vessel 14 through the bottom outlet 146 of the reaction vessel 14, the first pump 151 and the top inlet of the reaction vessel 14 until pH value and specific gravity detected by sampling are qualified, the outlet 151b of the first pump 151 is disconnected from the reaction vessel 14 and connected to the constant volume stirring tank 16, and the qualified cadmium chloride solution is supplied to the constant volume stirring tank 16. Note that, in the cadmium chloride mixed crystal hydrate solution production system, it is determined that both the pH reference of the lower/higher pH value and the specific gravity reference of the lower/higher specific gravity are ranges, and the aforementioned amount of the hydrogen chloride solution added and the amount of the cadmium oxide powder are determined on the pH reference and the specific gravity reference. Sampling of the pH and specific gravity can be measured by any suitable well known instrument.
The constant-volume stirring tank 16 is also communicated with the water supply line 11 in a controlled manner and is used for supplying water into the constant-volume stirring tank 16; the constant-volume stirring tank 16 is also in controlled communication with the HCl supply line 12 and is used for supplying HCl solution into the constant-volume stirring tank 16; the cadmium chloride solution preparation part 1 further comprises a second detection module 17, the second detection module 17 comprises a second pump 171, a second filter 172 and a second sampling line 173, and an inlet 171a of the second pump 171 is controlled to be communicated with the bottom outlet 161 of the constant volume stirring tank 16; the inlet 172a of the second filter 172 is controlled to communicate with the outlet 171b of the second pump 171; the second sampling line 173 is in controlled communication with the outlet 172b of the second filter 172, and the second sampling line 173 is used for performing pH and specific gravity sampling detection on the cadmium chloride solution in the constant volume stirring tank 16 through the second filter 172, the second pump 171 and the constant volume stirring tank 16 which are in communication; the outlet 172b of the second filter 172 is in controlled communication with the cadmium chloride crystal hydrate mixing section 2. Similarly, the second pump 171 employs a perfluoro pump to avoid corrosion by hydrogen chloride.
The second detection module 17 has the same function as the first detection module 15, and determines whether the pH value deviates from the pH reference and whether the specific gravity deviates from the specific gravity reference, the first detection module 15 is directed to the reaction vessel 14, and the second detection module 17 is directed to the constant volume stirring tank 16.
If the cadmium chloride solution sampled through the second sampling line 173 is qualified, the cadmium chloride solution in the constant volume stirring tank 16 enters the cadmium chloride crystal hydrate mixing part 2 through the bottom outlet 161, the second pump 171 and the second filter 172.
If the cadmium chloride solution sampled through the second sampling line 173 is not qualified, specifically, if the pH value sampled and detected through the second sampling line 173 is low, an amount of water needs to be added to raise the pH value, that is, the amount of water needed to be added is increased to the constant volume stirring tank 16 through the water supply line 12; if the pH value sampled and detected by the second sampling line 173 is too high, the amount of the hydrogen chloride needs to be added to increase the pH value, that is, the amount of the hydrogen chloride solution needed to be added is increased to the constant volume stirring tank 16 through the HCl supply line; if the specific gravity sampled and detected by the second sampling line 173 is low, the cadmium chloride solution in the constant volume stirring tank 16 is returned to the constant volume stirring tank 16 via the bottom outlet 161 and the second pump 171 and the amount of cadmium oxide powder to be added is increased to the reaction kettle 14 through the aforementioned cadmium oxide supply line 13 (specifically, through the communication control of the PLC control operation station 4 described later); if the specific gravity sampled and detected by the second sampling line 173 is too high, the amount of water to be added is required to decrease the specific gravity, that is, the amount of water required to be added is increased to the constant volume agitation tank 16 through the water supply line 12. Further, the cadmium chloride solution in the constant volume stirring tank 16 is returned to the constant volume stirring tank 16 via the bottom outlet 161 and the second pump 171 for the pH value lower/higher and the specific gravity lower/higher (both of these cases are not acceptable) of the sampling detection. Until the pH value and specific gravity sampled and detected by the second sampling line 173 pass, the cadmium chloride solution in the constant volume stirring tank 16 is supplied to the cadmium chloride crystal hydrate mixing unit 2 via the second pump 171 and the second filter 172.
The constant volume stirring tank 16 is also provided with a tail gas air pipe 162; the tail gas air pipe 162 is used for setting a micro negative pressure to prevent the tail gas in the constant volume stirring tank 16 from overflowing. The value of the micro negative pressure is only required to prevent the tail gas in the stirring tank 16 from overflowing.
Referring to fig. 1, in one embodiment, a cadmium chloride crystal hydrate mixing section 2 includes a mixing and agitation tank 21, a crystal hydrate supply line 22, and a weighing mechanism 23.

The mixing and stirring tank 21 further comprises a stirrer 212, and the stirrer 212 is used for stirring the mixture of the crystal hydrate and the cadmium chloride solution in the tank body 211. The weighing mechanism 23 is located below the tank body 211 of the mixing and stirring tank 21 and supports the tank body 211 of the mixing and stirring tank 21, and the weighing mechanism 23 is used for weighing the tank body 211 of the mixing and stirring tank 21.
Specifically, the tank 211 of the mixing and stirring tank 21 is controlled to communicate with the outlet 172b of the second filter 172 of the second detection module 17 of the cadmium chloride solution preparation unit 1, and after the second sampling line 173 of the second detection module 17 is qualified in sampling detection, the qualified cadmium chloride solution is pumped by the second pump 171 and filtered by the second filter 172 to be supplied to the tank 211 of the mixing and stirring tank 21.
In this embodiment, the weighing mechanism 23 displays and weighs in real time and interlocks (i.e., communicatively couples) the crystalline hydrate supply line 22, and automatically stops the crystalline hydrate supply line 22 from conveying crystalline hydrate after the weight is reached.
In one example, the crystalline hydrate is potassium chloride, but is not limited thereto, and any suitable crystalline hydrate may be employed as desired.

Likewise, to resist corrosion, in one example, the third pump 241 is a perfluorinated pump.
Similarly, whether the content of the crystal hydrate in the cadmium chloride mixed crystal hydrate solution meets the requirement or not is subject to the specified content range. If the crystalline hydrate content is below the specified content range, increasing the amount of crystalline hydrate required through crystalline hydrate feed line 22; if the crystal hydrate content is higher than the predetermined content range, the amount of the qualified cadmium chloride solution supplied is increased by the pumping of the second pump 171 of the cadmium chloride solution preparing section 1.

An inlet 262a of the fourth filter 262 is controlled to communicate with an outlet 261b of the fourth pump 261. The fourth sampling line 263 is controlled to be communicated with the outlet 262b of the fourth filter 262, and the fourth sampling line 263 is used for sampling and detecting the cadmium chloride mixed crystal hydrate solution in the finished product constant volume tank 25 through the communicated fourth filter 262, the fourth pump 261 and the finished product constant volume tank 25 to determine whether the content of the crystal hydrate in the cadmium chloride mixed crystal hydrate solution in the finished product constant volume tank 25 meets the requirement. The outlet 262b of the fourth filter 262 is also in controlled communication with the finished product constant volume tank 25, so as to return the cadmium chloride mixed crystal hydrate solution in the finished product constant volume tank 25 to the finished product constant volume tank 25 after sampling detection via the fourth sampling line 263 fails. The outlet 262b of the fourth filter 262 is also in controlled communication with the tank 211 of the mixing and stirring tank 21, so as to pump the cadmium chloride mixed crystal hydrate solution in the finished product constant volume tank 25 back to the tank 211 of the mixing and stirring tank 21 after the sampling detection is unqualified through the fourth sampling line 263.
Likewise, to resist corrosion, in one example, the fourth pump 261 is a perfluoropump.
Similarly, when the cadmium chloride mixed crystal hydrate solution in the finished product constant volume tank 25 is returned to the tank body 211 of the mixing and stirring tank 21 after the sampling detection is failed through the fourth sampling line 263, the crystal hydrate supplied through the crystal hydrate supply line 22 and the qualified cadmium chloride solution pumped by the second pump 171 of the cadmium chloride solution preparing unit 1 are adjusted as described above until the cadmium chloride mixed crystal hydrate solution in the finished product constant volume tank 25 is supplied to the filling unit 3 after the sampling detection is passed through the fourth sampling line 263.
