Description

Technical Field

[0001] The present application belongs to the technical field of automatic ignition of hydrogen chloride synthesis furnaces, and in particular relates to an automatic ignition gas replenishment and absorption device for a hydrogen chloride synthesis furnace. Background Art

[0002] At present, the ignition of the hydrogen chloride synthesis furnace has been changed to automatic ignition operation. The main control personnel notify the on-site personnel to control the ignition. The on-site personnel (or the central control personnel) turn on the ignition button. After the DCS receives the ignition gun ignition success signal, the hydrogen manual valve and the two hydrogen shut-off valves on the main line and the low-fire hydrogen valve are opened in turn; the flame is observed to be normal and the external flame detector starts detection; when any of the two flame detectors detects the flame signal, the chlorine manual valve and the two chlorine shut-off valves on the main line and the low-fire chlorine valve are opened in turn to ignite the synthesis furnace burner with a low fire. After observing that the flame in the furnace is normal, close the acid condensing ball valve and gradually close the negative pressure extraction system of the synthesis furnace. After everything is normal, the main control personnel close the synthesis furnace air supply valve and open the hydrogen and chlorine valves.

[0003] However, from the time the hydrogen chloride synthesis furnace is automatically ignited to the time the air supply valve is closed, a large amount of hydrogen chloride gas will be sprayed out from the air supply port along with hydrochloric acid, which will not only pollute the environment, but also corrode the on-site equipment and even cause failure and damage of the on-site equipment.

[0042] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0043] like Figure 1As shown, according to an embodiment of the present application, a device for automatically lighting and replenishing gas for a hydrogen chloride synthesis furnace is proposed, comprising: a holding tank 10, a vent pipe 11, a first one-way valve 12, an absorption pipe 13 and a second one-way valve 14; the holding tank 10 is filled with an absorbent; the vent pipe 11 is connected to the holding tank 10, and the first end of the vent pipe 11 is connected to the gas replenishment port; the first one-way valve 12 is arranged at the second end of the vent pipe 11, and the first one-way valve 12 is used to introduce air into the vent pipe 11; the first end of the absorption pipe 13 is connected to the vent pipe 11, and the second end of the absorption pipe 13 extends below the liquid level of the absorbent; the second one-way valve 14 is arranged at the second end of the absorption pipe 13, and the second one-way valve 14 is used to introduce gas into the absorbent.

[0044] The automatic furnace ignition gas replenishment and absorption device for hydrogen chloride synthesis furnace provided in the embodiment of the present application comprises a holding tank 10, a vent pipe 11, a first non-return valve 12, an absorption pipe 13 and a second non-return valve 14; a gas replenishment port is arranged on the furnace door of the original equipment, and the first end of the vent pipe 11 is connected to the gas replenishment port, and the first non-return valve 12 is arranged at the second end of the vent pipe 11, so that the vent pipe 11 is used to introduce air into the gas replenishment port in one direction, and at the same time, the mixture in the furnace is prevented from overflowing from the vent pipe 11, and gas replenishment is performed when the furnace is ignited to ensure that the hydrogen and oxygen in the synthesis furnace can be fully burned and reacted; by connecting the first end of the absorption pipe 13 to the vent pipe 11, the first non-return valve 12 is arranged at the second end of the absorption pipe 13, and the absorption pipe 13 is connected to the first end of the absorption pipe 13. A second one-way valve 14 is provided, and the second end of the absorption pipe 13 and the second one-way valve 14 are immersed in the absorbent of the holding tank 10, so that the hydrogen chloride gas and a small amount of hydrochloric acid overflowing from the gas replenishment port are passed into the absorbent through the vent pipe 11 and the absorption pipe 13, and the absorbent is prevented from flowing back into the absorption pipe 13, and the overflowing mixture is absorbed by the absorbent to process the overflowing mixture, so that only the gas not absorbed by the absorbent and the liquid after absorbing the mixture remain in the holding tank 10, so as to avoid the mixture directly overflowing from the gas replenishment port to pollute the environment, prevent the on-site equipment from being corroded and damaged, improve the safety of the synthesis furnace during the automatic ignition and combustion process, and facilitate subsequent processing. The device has a simple structure, integrates the gas replenishment function and the absorption function, can not only perform one-way gas replenishment on the gas replenishment port during the ignition process, but also absorb and process the mixture overflowing from the gas replenishment port, thereby improving the continuity and safety of the operation of the synthesis furnace.

[0045] In some examples, the vent pipe 11 can be disposed inside the holding tank 10 or outside the holding tank 10. When the vent pipe 11 is disposed inside the holding tank 10, the absorption tube 13 is completely located inside the holding tank 10, so that the vent pipe 11 is sealedly connected to the holding tank 10 to prevent gas leakage inside the holding tank 10. When the vent pipe 11 is disposed outside the holding tank 10, the first end of the absorption tube 13 is outside the holding tank 10, and the other end of the absorption tube 13 is inside the holding tank 10, so that the absorption tube 13 is sealedly connected to the holding tank 10 to prevent gas leakage inside the holding tank 10.

[0046] As a preferred solution, the absorbent is water, which is easily available. Hydrogen chloride gas is easily soluble in water. After absorbing hydrogen chloride and hydrochloric acid, the absorbent can turn into condensed acid, which can be discharged in a centralized manner for subsequent treatment.

[0047] It should be noted that before igniting the furnace, it is necessary to connect the ventilation pipe 11 of the device with the gas supply port of the synthesis furnace door; when the furnace is just ignited, the hydrogen and oxygen in the furnace burn, the furnace is under negative pressure, and the outside air enters the gas supply port from the first one-way valve 12 for gas supply; after the combustion releases heat, the furnace is under positive pressure, and the hydrogen chloride gas and a small amount of hydrochloric acid overflowing from the gas supply port are passed into the absorbent in the holding tank 10 through the absorption pipe 13 and the second one-way valve 14 to become condensed acid; after the furnace is ignited, the central control room closes the furnace door, and the on-site personnel close the original gas supply port control valve of the on-site equipment, and then remove the gas supply absorption device from the synthesis furnace to separate the gas supply absorption device from the synthesis furnace.

[0048] like Figure 1 As shown, in a feasible embodiment, the ventilation pipe 11 includes: an air inlet pipe 111 and a mixing pipe 112; the air inlet pipe 111 is connected to the outer wall of the holding tank 10, and a first one-way valve 12 is provided at the first end of the air inlet pipe 111; the mixing pipe 112 is arranged in the holding tank 10, the mixing pipe 112 is sealed and connected to the holding tank 10, the first end of the mixing pipe 112 is connected to the second end of the air inlet pipe 111, and the second end of the mixing pipe 112 is connected to the air supply port.

[0049] In this technical solution, a mixing tube 112 is arranged in the holding tank 10 and is sealedly connected to the holding tank 10 to prevent the gas in the holding tank 10 from overflowing from the interface between the mixing tube 112 and the holding tank 10; an air inlet pipe 111 is arranged outside the holding tank 10, and a first one-way valve 12 is arranged on the air inlet pipe 111, so that the air outside the holding tank 10 passes through the air inlet pipe 111 and the mixing tube 112 in turn and enters the air replenishing port to replenish air when the synthesis furnace is ignited; at the same time, it is ensured that when the material in the furnace burns and releases heat, the furnace is positively pressurized, and the overflowed hydrogen chloride gas and a small amount of hydrochloric acid will not overflow, thereby reducing pollution to the on-site environment and reducing damage to on-site equipment.

[0050] like Figure 1 As shown, in a feasible implementation manner, the absorption tube 13 is vertically arranged, the absorption tube 13 vertically extends below the liquid surface of the absorbent, and the first end of the absorption tube 13 is connected to the mixing tube 112 .

[0051] In this technical solution, the absorption tube 13 is connected to the middle of the mixing tube 112, and the absorption tube 13 is vertically arranged to pass the mixture in the absorption tube 13 vertically into the liquid surface of the absorbent, which helps the hydrogen chloride gas to be absorbed by the absorbent more quickly and improves the absorbency of the absorbent to the hydrogen chloride gas; at the same time, when the hydrogen chloride gas is vertically passed into the water absorbent, the resistance it encounters is relatively smaller, which can ensure that the gas can enter the water more smoothly, reduce energy loss, and enable the gas to be more evenly distributed in the absorbent, thereby improving the utilization rate of the gas.

[0052] like Figure 1 As shown, in a feasible embodiment, the automatic ignition gas-supplying absorption device for the hydrogen chloride synthesis furnace also includes: a connecting pipe 15 and a flange 16; the first end of the connecting pipe 15 is connected to the containing tank 10, and the connecting pipe 15 is connected to the ventilation pipe 11; the flange 16 is arranged at the second end of the connecting pipe 15, and the flange 16 is used to detachably connect the connecting pipe 15 to the furnace door, so that the connecting pipe 15 is connected to the gas-supplying port.

[0053] In this technical solution, the first end of the connecting pipe 15 is connected to the containing tank 10, and the second end of the connecting pipe 15 is connected to the flange 16, and the flange 16 is used to connect to the furnace door, so that the ventilation pipe 11 is connected to the air supply port through the connecting pipe 15, so that the air entering from the first one-way valve 12 can enter the air supply port through the connecting pipe 15, and the mixture overflowing from the air supply port can pass through the connecting pipe 15 and the ventilation pipe 11, and then pass into the absorbent from the absorption pipe 13 and the second one-way valve 14 for absorption; at the same time, the flange 16 is easy to connect and disassemble, which can improve the convenience of connecting the air supply absorption device with the furnace door.

[0054] like Figure 1 As shown, in a possible implementation manner, the connecting pipe 15 is a hose.

[0055] In this technical solution, the connecting pipe 15 is a hose, which reduces the difficulty of connecting the flange 16 to the furnace door, reduces the restrictions on the placement of the air supply absorption device, and is more convenient to use.

[0056] like Figure 1 As shown, in a feasible embodiment, the automatic ignition and gas replenishment absorption device for the hydrogen chloride synthesis furnace also includes: a drain port 17 and a drain valve 18; the drain port 17 is arranged at the bottom of the holding tank 10, and the drain port 17 is used to discharge the liquid in the holding tank 10; the drain valve 18 is arranged on the drain port 17.

[0057] In this technical solution, a drain port 17 and a drain valve 18 are provided at the bottom of the holding tank 10 so that the condensed acid liquid formed after the mixture is absorbed can be discharged in a centralized manner, thereby ensuring the safety of the gas replenishment absorption device during transportation.

[0058] Furthermore, the drain port 17 is detachably connected to the acid storage tank so that the condensed acid can be discharged centrally into the acid storage tank for centralized treatment.

[0059] like Figure 1 As shown, in a feasible implementation manner, the automatic ignition gas replenishment absorption device for the hydrogen chloride synthesis furnace further includes: a liquid level meter 19; the liquid level meter 19 is arranged on the outside of the holding tank 10, and the liquid level meter 19 is used to monitor the liquid level in the holding tank 10.

[0060] In this technical solution, a liquid level meter 19 is disposed on the outside of the holding tank 10. The liquid level meter 19 is used to monitor the liquid level in the holding tank 10, so as to quickly determine the time to replenish the absorbent, ensure that there is sufficient absorbent in the holding tank 10, and ensure the absorption effect of the mixture; at the same time, it is convenient to quickly determine the time to discharge the condensed acid, prevent the condensed acid from corroding the joint between the vent pipe 11 and the holding tank 10, ensure that the sealing of the holding tank 10 is not destroyed, and ensure that the gas in the holding tank 10 does not overflow.

[0061] like Figure 1 As shown, in a feasible embodiment, the automatic ignition gas replenishment absorption device of the hydrogen chloride synthesis furnace also includes: an exhaust port 20 and an exhaust valve 21; the exhaust port 20 is arranged at the top of the holding tank 10, and the exhaust port 20 is used to discharge the gas in the holding tank 10; the exhaust valve 21 is arranged on the exhaust port 20.

[0062] In this technical solution, an exhaust port 20 and an exhaust valve 21 are provided on the top of the holding tank 10 to discharge the remaining gas absorbed by the absorbent in the holding tank 10, that is, the gas not absorbed by the absorbent is discharged through the exhaust pipe for centralized treatment.

[0064] In this technical solution, a liquid inlet 22 and a liquid inlet valve 23 are provided at the top of the holding tank 10 to replenish the absorbent into the holding tank 10 when the absorbent is insufficient, thereby ensuring that the hydrogen chloride gas in the holding tank 10 is completely absorbed in the holding tank 10, so as to ensure the absorption and treatment effect of the gas overflowing from the gas replenishment port.

[0065] like Figure 1 As shown, in a feasible embodiment, the automatic ignition and gas replenishment absorption device for the hydrogen chloride synthesis furnace further includes: a moving wheel group 24; the moving wheel group 24 is arranged on the bottom surface of the containing tank 10, and the moving wheel group 24 includes at least one braking wheel.

[0066] In this technical solution, the moving wheel group 24 includes four moving wheels to facilitate moving the air-supplying absorption device to the desired position, thereby improving the flexibility of the air-supplying absorption device itself; at the same time, one of the moving wheels in the moving wheel group 24 is a braking wheel to ensure that when the air-supplying absorption device is connected to the furnace door, the air-supplying absorption device can be stably stopped, thereby ensuring the stability and reliability of the connection between the air-supplying absorption device and the furnace door.
