Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen chloride by-product steam equipment, in particular to a novel hydrogen chloride synthesis by-product steam device. Background Art

[0002] When chlorine and hydrogen react to generate hydrogen chloride, a large amount of reaction heat is released. Chlorine and hydrogen react to generate hydrogen chloride in the form of combustion in the synthesis furnace. The temperature of the center of the flame reaches above 2500℃, and the temperature of the generated hydrogen chloride gas is above 2000℃. This heat is quite considerable and can be used to produce steam as a by-product. There are two main methods for utilizing heat energy in hydrogen chloride synthesis in China:

[0003] One is to use a steel water-jacketed hydrogen chloride synthesis furnace to produce hot water as a byproduct;

[0004] Another method is to use a graphite-made hydrogen chloride synthesis furnace to produce hot water or steam as a by-product.

[0005] Chinese patent CN111620305B discloses a device and method for greatly increasing the by-product steam of hydrogen chloride synthesis. The device is provided with a pure water tank, and pure water absorbs heat to generate superheated water, and the superheated water is passed into a steam flash tank to convert the superheated water into steam. This method uses superheated water for heat exchange, and the superheated water has the characteristics of high thermal efficiency and low energy consumption, and can fully recover heat energy;

[0006] However, the pure water in the patented pure water tank will be continuously consumed. In order to ensure that there is enough pure water in the pure water tank, it needs to be continuously replenished. The common replenishment method is to monitor the liquid level through a sensor, and then replenish the pure water by controlling the valve after monitoring. However, the generation of superheated water requires certain requirements on the pressure in the pure water tank. In order to prevent the superheated water from boiling during the transportation process, not only pure water is required to be used as a carrier, but also the pressure requirement needs to be met. For the sensor, the environment in the pure water tank is relatively harsh. Therefore, the method of detecting the liquid level through a sensor is not suitable for this environment. Therefore, a new hydrogen chloride synthesis by-product steam device is proposed to solve the above-mentioned problems. Utility Model Content

[0007] Based on the above description, the utility model provides a novel hydrogen chloride synthesis by-product steam device to solve the problem that the method of using a sensor to monitor the liquid level to supplement pure water is not applicable in a pure water tank.

[0008] The utility model provides a technical solution to the above technical problems as follows: a novel hydrogen chloride synthesis by-product steam device, comprising: a main tank body and a top cover, wherein the top cover is arranged at the top end of the main tank body and comprises a hollow connecting piece and a liquid inlet pipe, a sealing mechanism comprises a mounting sleeve, a liquid inlet block and a floating piece, the mounting sleeve is arranged on the outside of the hollow connecting piece, the liquid inlet block is arranged on the inside of the mounting sleeve through a gasket and a nut, and comprises a liquid inlet and a movable cavity, and the floating piece is arranged on the inside of the movable cavity and extends to the outside of the liquid inlet block.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the top cover includes a cover body, a hollow connector is arranged inside the cover body, and a liquid inlet pipe is arranged at the top end of the cover body.

[0011] Furthermore, the hollow connecting piece is a convex hollow piece, and the liquid inlet pipe is connected to the hollow connecting piece.

[0012] Furthermore, the installation sleeve includes a first half-cylinder and a second half-cylinder, and an annular groove and an opening are sequentially provided on opposite sides of the first half-cylinder and the second half-cylinder from top to bottom, and the hollow connecting piece is arranged inside the annular groove.

[0013] Furthermore, the outer surfaces of the first half cylinder and the second half cylinder are provided with mounting ears, and the first half cylinder and the second half cylinder are provided with a positioning hole and a positioning column on opposite sides thereof, respectively, and the positioning column extends to the inside of the positioning hole.

[0014] Furthermore, the liquid inlet block includes blocks, and the blocks are connected to each other by screws.

[0015] Furthermore, one side of the block is provided with a liquid inlet, a liquid storage hole, an active cavity, a connecting hole and an active groove which are interconnected from top to bottom, and the diameter of the top of the active cavity is smaller than the diameter of the bottom thereof.

[0016] Furthermore, a sealing groove, a threaded column and a liquid outlet are provided on the outer surface of the block, a sealing ring is provided inside the sealing groove, the sealing ring contacts the inner wall of the liquid inlet pipe, and the liquid outlet is communicated with the active cavity.

[0019] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0020] 1. By providing components such as an installation sleeve, a liquid inlet block, and a floating member, through the cooperation relationship between the liquid inlet block and the installation sleeve, the floating member can only move vertically. When pure water is introduced through the liquid inlet pipe, the pure water flows through the liquid inlet block and then enters the interior of the main tank.

[0035] Please refer to Figure 1-Figure 3 , a novel hydrogen chloride synthesis by-product steam device, comprising:

[0036] Main tank body 1; and

[0037] Top cover 2, which is arranged at the top of the main tank body 1 and includes a hollow connecting piece 22 and a liquid inlet pipe 23. The top cover 2 includes a cover body 21. A hollow connecting piece 22 is arranged inside the cover body 21. A liquid inlet pipe 23 is arranged at the top of the cover body 21. The hollow connecting piece 22 is a convex character hollow piece. The liquid inlet pipe 23 communicates with the hollow connecting piece 22.

[0038] Based on the above, the hollow connecting piece 22 serves to position the mounting sleeve 3, and when pure water is introduced into the main tank body 1 through the liquid inlet pipe 23, the pure water can flow through the mounting sleeve 3.

[0039] As Figure 2-Figure 5 shown, the mounting sleeve 3 is arranged outside the hollow connecting piece 22.

[0040] The mounting sleeve 3 includes a first half cylinder 31 and a second half cylinder 32. Annular grooves 33 and openings 35 are sequentially arranged from top to bottom on the opposite sides of the first half cylinder 31 and the second half cylinder 32. The hollow connecting piece 22 is arranged inside the annular groove 33. Mounting ears 34 are arranged on the outer surfaces of the first half cylinder 31 and the second half cylinder 32. Positioning holes 36 and positioning posts 37 are respectively arranged on the opposite sides of the first half cylinder 31 and the second half cylinder 32, and the positioning posts 37 extend into the positioning holes 36.

[0041] Based on the above, the first half cylinder 31 and the second half cylinder 32 are connected to each other by screws and nuts, and the connected mounting sleeve 3 is arranged outside the hollow connecting piece 22. The positioning posts 37 and the positioning holes 36 cooperate with each other to increase the stability of the connection between the two half cylinders. The arrangement of the opening 35 enables the threaded post 48 to extend outside the mounting sleeve 3.

[0042] As Figure 2-Figure 4 and Figure 6 shown, the liquid inlet block 4 is arranged inside the mounting sleeve 3 through a backing plate 7 and a nut, and includes a liquid inlet 42 and a movable cavity 44.

[0043] The liquid inlet block 4 includes a block body 41, and the block bodies 41 are connected to each other by screws.

[0044] On the opposite sides of the block body 41, a liquid inlet 42, a liquid storage hole 43, a movable cavity 44, a communication hole 45, and a movable groove 46 are sequentially arranged from top to bottom and are communicated with each other. The diameter of the top of the movable cavity 44 is smaller than that of the bottom.

[0045] Sealing grooves 47, threaded posts 48, and liquid outlet holes 49 are arranged on the outer surface of the block body 41. A sealing ring 6 is arranged inside the sealing groove 47, and the sealing ring 6 is in contact with the inner wall of the liquid inlet pipe 23. The liquid outlet hole 49 is communicated with the movable cavity 44. The threaded post 48 penetrates through the opening 35. A backing plate 7 in contact with the outer surface of the mounting sleeve 3 is arranged outside the threaded post 48.

[0046] Based on the above, pure water flows through the liquid inlet 42, the liquid storage hole 43, and the movable cavity 44 and is discharged at the liquid outlet hole 49. The liquid storage hole 43 plays a role in temporarily storing pure water to avoid a large impact when pure water is introduced. The movable cavity 44 provides a moving space for the floating member 5, enabling the floating member 5 to move inside the movable cavity 44 along the direction of the communication hole 45. The sealing ring 6 plays a sealing effect.

[0047] As Figure 2-Figure 4 and Figure 7 shown, the floating member 5 is arranged inside the movable cavity 44 and extends outside the liquid inlet block 4.

[0048] The floating member 5 includes a hollow floating plate 51, and a water permeable hole 52 and a connecting vertical rod 53 are arranged on the upper surface of the hollow floating plate 51. A sealing ball 54 located inside the movable cavity 44 is arranged at the top end of the connecting vertical rod 53. The diameter of the sealing ball 54 is larger than the diameter of the top of the movable cavity 44 and smaller than the diameter of its bottom. The hollow floating plate 51 is arranged inside the movable groove 46.

[0049] Based on the above, the hollow floating plate 51 moves upward under the action of the buoyancy of pure water, so that the floating member 5 can move vertically following the height of the liquid surface. The arrangement of the water permeable hole 52 avoids the residue of pure water on the surface of the hollow floating plate 51. The sealing ball 54 plays a role in blocking the movable cavity 44.

[0050] During actual use of this embodiment, pure water is introduced into the liquid inlet 42 through the liquid inlet pipe 23. The pure water flows through the liquid inlet 42, the liquid storage hole 43, and the movable cavity 44 and is discharged into the main tank 1 at the liquid outlet hole 49. After the discharged pure water is stored in the main tank 1, the liquid level rises;

[0051] After the pure water liquid level rises and contacts the lower surface of the hollow floating plate 51, the hollow floating plate 51 moves upward under the action of buoyancy, and then pushes the sealing ball 54 upward to block the movable cavity 44, so that pure water cannot enter the main tank 1 normally;

[0052] When the pure water is consumed, the floating member 5 descends under the action of gravity. At this time, there is a gap between the sealing ball 54 and the movable cavity 44, enabling pure water to enter the main tank 1 again, achieving the effect of automatic water replenishment;

[0053] According to different actual requirements, by loosening the nut and adjusting the gap between the liquid inlet block 4 and the top cover 2, the height of the floating member 5 is also changed to achieve the effect of adjusting the storage amount of pure water in the main tank 1;

[0054] This device achieves the effect of automatic water replenishment through the blocking mechanism, which is more reliable compared to the method of using a sensor, a precision instrument, and the blocking mechanism is a mechanical structure, making it more adaptable to the pressurized and humid environment.

[0055] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
