Description

Technical Field

[0001] This utility model relates to the field of hot water tank technology, specifically to a convertible hot water tank with a pressure control regulating valve. Background Technology

[0002] The process of producing vinyl chloride by reacting hydrogen chloride with acetylene using mercuric chloride catalyst requires preheating before entering the converter. The higher the preheater temperature, i.e., the initial converter temperature, the better the catalytic reaction of hydrogen chloride and acetylene under the mercuric chloride catalyst. The reaction within the converter is exothermic, with the heat released by the vaporization of hot water between the tubes being carried away. Higher hot water temperatures result in better heat removal. However, due to the low local atmospheric pressure, the hot water temperature can only reach 92 degrees Celsius, which has long plagued the conversion production, leading to high catalyst consumption, high alkali consumption, and high acetylene levels before the machine, posing safety risks.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: In the existing chlorination process of chlor-alkali chemical plants, the hot water in the conversion process is limited by the atmospheric pressure at high altitudes, resulting in low temperature and low latent heat of vaporization, which causes the heat of reaction in the converter to not be removed in time. Utility Model Content

[0004] The purpose of this invention is to provide a conversion hot water tank with a pressure control regulating valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conversion hot water tank with a pressure control regulating valve, comprising a hot water tank body, both ends of the hot water tank body are equipped with fixed plates, and several support columns are fixedly connected to the bottom of the hot water tank body, wherein an inlet pipe is provided through the center of one of the fixed plates, and an outlet pipe is provided through the center of the other fixed plate. Both the inlet pipe and the outlet pipe are equipped with flanges at one end. An air inlet pipe is provided through the top of the hot water tank. A return air pipe is provided through one side of the air inlet pipe. The bottom of the return air pipe is provided through the top of the hot water tank. A pressure control valve is provided in the middle of the return air pipe. The pressure control valve includes a valve body, a gate body movably disposed in the middle of the valve body, a lead screw passing through the top of the gate body, the top of the lead screw passing through the top of the valve body, a bearing disposed at the upper part of the lead screw and the opening of the valve body, a rotating ring fixedly connected to the top of the lead screw, and the bottom of the lead screw movably connected to the inner wall of the valve body.

[0006] The beneficial effects of this utility model are as follows: under the action of the pressure control valve, steam can flow back, thereby pressurizing the inside of the hot water tank and allowing the water temperature to reach the boiling point. The valve body can be opened and closed quickly by moving the spherical gate body up and down, and the airtightness of the valve body can be ensured, so that the heat of the converter reaction can be removed in time.

[0007] To achieve good airtightness of the valve body: The gate body is further configured to have a spherical structure, and the size of the gate body is consistent with the inner diameter of the return air pipe. The gate body moves up and down along the lead screw.

[0008] By adopting the above technical solution, the gate body can ensure the airtightness of the valve body.

[0009] To achieve hot water inflow and outflow in the hot water tank and improve water output efficiency: The configuration is further defined as follows: the horizontal center lines of the hot water tank, the fixed plate, the inlet pipe, and the outlet pipe are aligned.

[0010] By adopting the above technical solution, hot water can be easily introduced and removed, improving the overall process efficiency.

[0011] To achieve a tight seal in the hot water tank: The fixed plate is further configured such that: the fixed plate includes a fixed plate body, and a sealing rubber is provided on one side of the fixed plate body, and a water inlet is provided in the center of the fixed plate body.

[0012] By adopting the above technical solution, sealing rubber is installed on the inner wall of the fixed plate to ensure sealing.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0017] Please see Figures 1 to 4A conversion hot water tank with a pressure control regulating valve includes a hot water tank body 1. Both ends of the hot water tank body 1 are equipped with fixed plates 2. Several support columns 3 are fixedly connected to the bottom of the hot water tank body 1. An inlet pipe 4 is passed through the center of one of the fixed plates 2, and an outlet pipe 5 is passed through the center of the other fixed plate 2. A flange 6 is provided at one end of the liquid inlet pipe 4 and the liquid outlet pipe 5. An air inlet pipe 7 is provided through the top of the hot water tank 1. A return air pipe 8 is provided through one side of the air inlet pipe 7. The bottom of the return air pipe 8 is provided through the top of the hot water tank 1. A pressure control valve 9 is provided in the middle of the return air pipe 8. The pressure control valve 9 includes a valve body 901, a gate body 902 movably disposed in the middle of the valve body 901, a lead screw 903 passing through the top of the gate body 902, the top of the lead screw 903 passing through the top of the valve body 901, a bearing being provided at the upper part of the lead screw 903 and the opening of the valve body 901, a rotating ring 904 being fixedly connected to the top of the lead screw 903, and the bottom of the lead screw 903 being movably connected to the inner wall of the valve body 901.

[0018] In this embodiment, as Figure 4 As shown, the gate body 902 has a spherical structure, and the size of the gate body 902 is consistent with the inner diameter of the return air pipe 8. The gate body 902 moves up and down along the screw 903.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, the horizontal center lines of the hot water tank 1, the fixed plate 2, the inlet pipe 4, and the outlet pipe 5 are aligned.

[0020] In this embodiment, as Figure 3 As shown, the fixed plate 2 includes a fixed plate body 201, and a sealing rubber 202 is provided on one side of the fixed plate body 201, and a water inlet 203 is provided in the center of the fixed plate body 201.

[0021] The working process of this hot water conversion tank equipped with a pressure control regulating valve is as follows: First, unboiled hot water is introduced into the hot water tank 1 through the liquid inlet pipe 4. Steam is then introduced into the hot water tank 1 through the air inlet pipe 7. Manually rotating the rotating ring 904 will drive the screw 903 to rotate, thereby allowing the gate body 902 to move up and down to realize the air passage and air closure of the valve body 901. The spherical gate body 902 has the same inner diameter as the return air pipe 8 to ensure the airtightness of the return air pipe 8, so that the internal pressure rises to 26 kPa, which is compensated to the standard atmospheric pressure of 103 kPa, and the hot water temperature reaches the boiling point, thereby increasing the efficiency of preheating for subsequent catalytic reactions. The hot water that has reached the boiling point is discharged from the hot water tank 1 through the liquid outlet pipe 5. The two ends of the hot water tank 1 are sealed with rubber 202 (model: Sunray YS-2100) on the fixed plate 201 to ensure the airtightness of the hot water tank 1.
