The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
The double-layer reaction kettle for copper sulfate in the embodiment is shown in fig. 1, and comprises a reaction kettle body 1, a kettle bottom 2 and an outer layer jacket 3, wherein the reaction kettle body 1 comprises a kettle cover 11 and a plurality of annular walls 12, the annular walls 12 are sequentially connected from bottom to top, the bottom of the kettle cover 11 is connected with the top of the uppermost annular wall 12, and a hollow reaction cavity is defined by the annular walls 12 and the kettle cover 11; the bottom of the annular wall 12 positioned at the lowest part is connected with the kettle bottom 2; the outer layer jacket 3 surrounds the outer side of the reaction kettle body 1, the reaction kettle body 1 and the outer layer jacket 3 are hollow, and the bottom of the outer layer jacket 3 is connected with the kettle bottom 2; the periphery of the kettle bottom 2 extends outwards to form a mounting flange 21, and the mounting flange 21 is used for fixing the double-layer reaction kettle on the ground.
In the long-term use process of the reaction kettle, the reaction kettle body 1 can be continuously corroded, once the reaction kettle is corroded and penetrated, copper sulfate solution can leak out from the perforated part of the reaction kettle body 1, sulfur trioxide gas can be generated by the copper sulfate solution at high temperature, and the perforated part is difficult to weld due to the strong oxidizing property of sulfur trioxide; the utility model discloses creatively sets up outer jacket 3 in the outside of the reation kettle body 1, so set up the life-span that can make the increase double-deck reation kettle, when the reation kettle body 1 is pierced through by the corruption, the copper sulfate solution in the reation kettle body 1 permeates out from the perforation position, and remain between reation kettle body 1 and outer jacket 3, because the speed that copper sulfate solution oozes from the perforation position is slower, it also can continue normal use to need not to repair reation kettle body 1 this moment, can not influence the normal production of copper sulfate, can reduce cost of maintenance effectively, double-deck reation kettle's life-span has been increased by a wide margin.
The top of the outer layer jacket 3 is provided with a water outlet 31, the bottom of the outer layer jacket 3 is provided with a water inlet 32 and a water outlet 33, and the water inlet 32 is used for filling water between the reaction kettle body 1 and the outer layer jacket 3.
When the double-layer reaction kettle is used for producing copper sulfate, clear water is filled between the reaction kettle body 1 and the outer-layer jacket 3, so that the wall surface of the reaction kettle body 1 can be cooled, the temperature of the wall surface of the reaction kettle body 1 is reduced, the corrosion speed of copper sulfate solution in the reaction cavity on the wall surface of the reaction kettle body 1 is reduced, the reaction kettle is protected, in addition, leaked copper sulfate can be taken away due to continuous circulation of water, the corrosion of the copper sulfate on the reaction kettle body 1 and the outer-layer jacket 3 is further slowed down, and the water between the reaction kettle body 1 and the outer-layer jacket 3 is difficult to permeate into the reaction cavity due to the large pressure in the reaction kettle body 1, so the production quality of the copper sulfate is not influenced; certainly, the reaction kettle is also provided with a reservoir and a water pump, the water pump is connected between the reservoir and the water inlet 32, the water outlet 31 is connected to the reservoir, when in production, the water pump continuously adds clean water into the water inlet 32, and after the space between the reaction kettle body 1 and the outer jacket 3 is filled with the clean water, the clean water flows back into the reservoir from the water outlet 31 for heat dissipation, so that the clean water between the reaction kettle body 1 and the outer jacket 3 can continuously circulate to cool the wall surface of the reaction kettle body 1; the water outlet 33 is used for emptying the clear water between the reaction kettle body 1 and the outer layer jacket 3.
The height of the reaction kettle body 1 is 8-16 m.
The existing reaction kettle is 3-8m, the height of the reaction kettle body 1 is increased to 8-16m, the capacity of the reaction kettle body 1 can be increased, more copper sulfate can be produced by the reaction kettle body 1 at one time, and the yield can be effectively increased; the reaction kettle body 1 is formed by sequentially connecting a plurality of annular walls 12 from bottom to top, so that the processing difficulty of the reaction kettle can be reduced.
The annular walls 12 are connected by welding; the kettle cover 11 is connected with the annular wall 12 in a welding mode; the annular wall 12 is connected with the kettle bottom 2 by welding; the outer layer jacket 3 and the kettle bottom 2 are connected by welding.
Because the reaction kettle body 1 does not need to be frequently disassembled and assembled after being put into production, the welding connection has better connection strength and sealing performance, so that higher pressure can be borne in the reaction kettle body 1, and the welding sealing performance is higher, so that the copper sulfate can be better prevented from leaking.
The mounting flange 21 is fixed to the ground through explosive bolts, and the number of the explosive bolts is at least 8.
The mounting flange 21 can be fixed on the ground through the explosive bolts, so that the reaction kettle body 1 is prevented from being displaced due to vibration, and meanwhile, the reaction kettle body 1 is prevented from being toppled; the explosive bolts are arranged to be at least 8 bolts, so that the reaction kettle body 1 can be better fixed.
The reaction kettle body 1 and the outer layer jacket 3 are both made of stainless steel.
The stainless steel has better corrosion resistance, and the stainless steel is used as the wall surface of the reaction kettle, so that the corrosion speed of the copper sulfate solution to the wall surface of the reaction kettle can be effectively slowed down, and the service life of the reaction kettle body 1 is prolonged.
The distance between the inner wall of the outer layer jacket 3 and the outer wall of the reaction kettle body 1 is 3-8 cm.
Set up like this and to keep certain distance between can making outer jacket 3 and the reation kettle body 1 to pack the clear water between the jacket 3 to the reation kettle body 1 and outer jacket, when the distance between the inner wall that outer jacket 3 and the outer wall of the reation kettle body 1 is greater than 8cm in addition, can lead to reation kettle's volume too big, the extravagant ground space of mill.
