Description

Technical Field

[0001] This utility model belongs to the technical field of rotating high-temperature reaction equipment, specifically relating to a horizontal rotating high-temperature reaction system with a safety enclosure. Background Technology

[0002] In the industrial sector, especially in chemical, cement, biochemical, pharmaceutical, and new materials fields, high-temperature reaction equipment with rotational capabilities is a high-performance reactor. Rotary kilns, for example, provide high temperature and pressure for chemical reactions while simultaneously rotating, allowing materials within the reactor to constantly tumble or flow, improving contact efficiency and thus reaction efficiency. The reactants within a rotary kiln are in various states, including gases, solids with small particle sizes, and liquids. Because rotary kilns are horizontal, the sealing requirements are stringent to prevent internal material leakage. However, currently, rotary kilns operate under high temperature and pressure conditions, and their considerable weight leads to thermal expansion and contraction, which can severely deform the kiln body. This is extremely detrimental to the sealing connection between the kiln's ends and the sealing device, easily resulting in leaks. Utility Model Content

[0003] The technical problem this invention aims to solve is that, under high temperature and high pressure, the horizontal rotating high-temperature reaction equipment deforms due to thermal expansion and contraction. Furthermore, the deformation becomes more severe and rapid when the equipment is rotating, ultimately leading to material leakage inside the reactor and causing a production safety accident.

[0004] This utility model provides a horizontal rotating high-temperature reaction system with a safety enclosure, including a horizontal rotating reactor, an enclosure and a rotating device. The rotating reactor is located inside the enclosure, and the rotating device is wholly or partially located inside the enclosure. The rotating device is used to drive the rotating reactor to rotate, and sealing devices are provided at both ends of the rotating reactor.

[0005] The outer cover is connected to the air inlet pipe, which introduces protective gas into the inner part of the outer cover. The protective gas is located between the outer cover and the rotary reactor, providing a gas-sealed environment for the rotary reactor. The outer cover remains stationary and remains sealed during production.

[0006] The rotary reactor is connected to process piping that supplies reactants to the reactor. The process piping passes through the side wall of the outer casing and connects to the interior of the rotary reactor.

[0007] Optionally, the bottom of the outer cover is supported by the ground or by a base to improve the stability of the outer cover.

[0008] Optionally, the rotary reactor is provided with sealing devices at both ends, and the rotating device is connected to the rotary reactor through its own driving component and drives the rotary reactor to rotate.

[0009] Optionally, when the rotating device is located inside the outer cover, the driving component of the rotating device is located inside the outer cover, and the other parts of the rotating device are located outside the outer cover. The outer cover is provided with a sealing component at the position where the rotating device penetrates the outer cover.

[0010] Optionally, the process piping includes a gas supply pipe, an exhaust pipe, a material supply pipe, and a discharge pipe. One end of the gas supply pipe is connected to a gas source device outside the outer casing, and the other end passes through the side wall of the outer casing and connects to the upstream side of the rotary reactor to input process gas into the rotary reactor. One end of the material supply pipe is connected to a feeding device outside the outer casing, and the other end passes through the side wall of the outer casing and connects to the upstream side of the rotary reactor to input reactants into the rotary reactor.

[0011] One end of the exhaust pipe is connected to the downstream side of the rotary reactor, and the other end passes through the side wall of the outer casing and is connected to the gas collection device outside the outer casing, so as to output the waste gas generated by the reaction to the gas collection device; one end of the discharge pipe is connected to the downstream side of the rotary reactor, and the other end passes through the side wall of the outer casing and is connected to the material collection device outside the outer casing, so as to output the product to the material collection device.

[0012] Optionally, the outer cover is also connected to an exhaust pipe, one end of which is connected to a gas collecting device and the other end to the outer cover, so that excess gas inside the outer cover is output to the gas collecting device for temporary storage; one end of the inlet pipe is connected to a protective gas cylinder and the other end is connected to the outer cover, so as to input protective gas into the outer cover; the inlet pipe and the exhaust pipe do not contact the rotating reactor.

[0013] Alternatively, the protective gas may be a gas that does not contain oxygen.

[0014] Optionally, there is a pressure difference between the air pressure inside the outer casing and the air pressure inside the rotary reactor, forming a gas-sealed environment between the outer casing and the rotary reactor; a pressure gauge is installed on the outer casing to monitor the pressure inside the outer casing in real time.

[0015] Optionally, the outlet pipe is equipped with a gas detection device to detect the composition of the gas output from the outer casing in real time and determine whether there is a gas leak inside the rotary reactor.

[0016] If no gas detection device is provided, optionally, the gas outlet pipe is equipped with an openable and closable sampling branch pipe for sampling the gas output from the outer cover, and after detection, determining whether the gas inside the rotary reactor is leaking.

[0017] The horizontal rotating high-temperature reaction system with a safety enclosure described in this utility model has the following beneficial effects:

[0018] (1) The outer cover encloses the rotary reactor inside the outer cover. The outer cover not only provides insulation and protection for the rotary reactor, but also does not require a high degree of sealing for the rotary reactor. Even if the rotary reactor leaks, the leaked gas or solid can enter the outer cover. During production, the outer cover remains sealed, and the gas or solid leaking from the rotary reactor can be kept inside the outer cover and will not leak to the outside of the outer cover. This isolates the rotary reactor from the external environment. The rotary reactor does not come into contact with the outer cover, which can essentially ensure the safety of production.

[0019] (2) The outer cover is stationary and requires virtually no maintenance, allowing for long-term safe use;

[0020] (3) A protective gas is filled between the outer casing and the rotary reactor to provide a gas-sealed environment for the rotary reactor. Gas leaking from the rotary reactor enters the outer casing. When the gas pressure inside the outer casing rises to the same level as the pressure inside the rotary reactor, the gas inside the rotary reactor will no longer leak. Attached Figure Description

Detailed Implementation

[0024] This embodiment provides a horizontal rotating high-temperature reaction system with a leak-proof outer casing, such as... Figures 1-2 As shown, it includes a horizontal rotary reactor 1, an outer casing 2, and a rotating device 3. The rotary reactor 1 is located inside the outer casing 2, and the rotating device 3 is wholly or partially located inside the outer casing 2. The rotating device 3 is used to drive the rotary reactor 1 to rotate. Sealing devices are provided at both ends of the rotary reactor 1.

[0025] The outer cover 2 is connected to the air inlet pipe 4, which introduces protective gas into the outer cover 2. The protective gas is located between the outer cover 2 and the rotary reactor 1, providing a gas-sealed environment for the rotary reactor 1. The outer cover 2 remains stationary and is kept sealed during production.

[0026] The rotary reactor 1 is connected to a process pipeline that provides reactants to the rotary reactor 1. The process pipeline passes through the side wall of the outer casing 2 and connects to the interior of the rotary reactor.

[0027] Optionally, the bottom of the outer cover 2 is supported by the ground or by a base to improve the stability of the outer cover 2; when the bottom of the outer cover 2 is supported by the ground, a sealing component is provided at the bottom of the outer cover 2 to maintain the airtightness of the outer cover 2.

[0028] Optionally, the rotary reactor 1 is provided with sealing devices at both ends, and the rotating device 3 is connected to the rotary reactor 1 through its own driving component and drives the rotary reactor 1 to rotate.

[0029] Optionally, when the rotating device 3 is partially inside the outer cover 2, the driving component of the rotating device 3 is inside the outer cover 2, and the other parts of the rotating device 3 are outside the outer cover 2. The outer cover 2 is provided with a sealing component at the position where the rotating device 3 enters the outer cover 2.

[0030] Optionally, the process piping includes a gas supply pipe 6, an exhaust pipe 7, a material supply pipe 8, and a discharge pipe 9. One end of the gas supply pipe 6 is connected to a gas source device 10 outside the outer casing 2, and the other end passes through the side wall of the outer casing 2 and is connected to the upstream side of the rotary reactor 1 to input process gas into the rotary reactor 1. One end of the material supply pipe 8 is connected to a feed device 11 outside the outer casing 2, and the other end passes through the side wall of the outer casing 2 and is connected to the upstream side of the rotary reactor 1 to input reactants into the rotary reactor 1.

[0031] One end of the exhaust pipe 7 is connected to the downstream side of the rotary reactor 1, and the other end passes through the side wall of the outer cover 2 and is connected to the gas collection device 12 outside the outer cover 2, so as to output the waste gas generated by the reaction to the gas collection device 12; one end of the discharge pipe 9 is connected to the downstream side of the rotary reactor 1, and the other end passes through the side wall of the outer cover 2 and is connected to the material collection device 13 outside the outer cover 2, so as to output the product to the material collection device 13.

[0032] Optionally, the gas supply pipe 6, exhaust pipe 7, material supply pipe 8, and discharge pipe 9 are all provided with sealing components at the locations where they pass through the outer cover 2, so as to prevent the connection of process pipelines from affecting the sealing performance of the outer cover 2.

[0033] The outer cover 2 is equipped with sealing components at the locations where the rotating device 3, air supply pipe 6, exhaust pipe 7, material supply pipe 8, and discharge pipe 9 pass through the outer cover 2, to ensure the sealing performance of the outer cover 2. Although there are many locations, the outer cover 2 remains stationary. The above-mentioned sealing components are simple to operate, easy to maintain, and have a significant sealing effect.

[0034] The shape of the outer cover 2 is not limited, as long as it adapts to the shape of the internal rotating reactor 1. The outer cover 2 is hollow, which reduces its weight and saves costs. The rotating reactor 1 and the interspersed process pipelines inside the outer cover 2 can enhance the stability of the outer cover 2.

[0035] Optionally, the outer cover 2 is also connected to an air outlet pipe 5. One end of the air outlet pipe 5 is connected to the gas collection device 12, and the other end is connected to the outer cover 2, so that excess gas in the outer cover 2 is output to the gas collection device 12 for temporary storage.

[0036] One end of the inlet pipe 4 is connected to the protective gas cylinder 14, and the other end is connected to the outer cover 2, so as to input protective gas into the outer cover 2; the inlet pipe 4 and the outlet pipe 5 do not contact the rotary reactor 1.

[0037] Further optionally, the protective gas is a gas that does not contain oxygen; preferably, the protective gas is an inert gas that does not contain oxygen.

[0038] Optionally, there is a pressure difference between the air pressure inside the outer casing 2 and the air pressure inside the rotary reactor 1, forming a gas-sealed environment between the outer casing 2 and the rotary reactor 1; the outer casing 2 is equipped with a pressure gauge to monitor the pressure inside the outer casing in real time.

[0039] Optionally, the air pressure inside the outer casing 2 is lower than that of the rotary reactor. High-temperature gas or solid leaking from the rotary reactor 1 enters the outer casing 2 and encounters the gas inside the outer casing 2. Since there is no oxygen inside the outer casing 2, it prevents the material from deflagration or explosion. When the sealing device of the rotary reactor 1 fails, the gas inside the rotary reactor 1 leaks into the outer casing 2. The original gas sealing environment inside the outer casing 2 will stop leaking when the air pressure inside the outer casing 2 rises to the same level as the pressure inside the rotary reactor 1.

[0040] Optionally, the gas pressure inside the rotary reactor 1 is lower than the gas pressure inside the outer casing 2, so that the gas inside the rotary reactor 1 cannot leak into the outer casing 2.

[0041] Optionally, the outlet pipe 5 is equipped with a gas detection device 15 for real-time detection of the gas composition output from the outer casing 2 to determine whether there is a gas leak inside the rotary reactor 1. The type of gas detection device is selected appropriately based on the type of gas inside the rotary reactor 1.

[0042] When gas leaks inside the rotary reactor, it can be detected in time by the gas detection device. The high-precision gas detection device has a detection capability at the ppm level and is very sensitive. It can detect the leak in the early stages of a small leak in the rotary reactor and issue an alarm in time, so that dangers and accidents can be dealt with at an extremely early stage.

[0043] If no gas detection device is provided, optionally, the gas outlet pipe 5 is equipped with an openable and closable sampling branch pipe for sampling the gas output from the outer cover 2. After detection, it is determined whether the gas in the rotary reactor 1 is leaking.

[0044] Optionally, the outer cover 2 is provided with an openable and closable inspection door to facilitate the inspection and maintenance of the equipment inside the outer cover 2; the outer cover 2 is provided with a viewing window to facilitate observation of the working status of the equipment inside the outer cover 2.

[0045] Optionally, the wires of the rotary reactor 1 and the rotating device 3 extend out of the outer cover 2 and are connected to a power source outside the outer cover 2.

[0046] The rotary reactor, rotating device, and sealing device described in this utility model are all conventional industrial equipment in the industrial field, such as cylindrical rotary kilns, cement rotary kilns, gear-type rotating devices, roller-type rotating devices, flexible sealing devices, labyrinth-type sealing devices, cylinder-type sealing devices, spring lever-type sealing devices, asbestos rope end-face friction sealing devices, graphite block sealing devices, movable slip ring-type sealing devices, and stacked spring plate sealing devices, etc., and can all be improved by applying the technology of this utility model.
