Description
Technical Field
The utility model relates to the field of coke oven equipment in steel plants, in particular to a vertical water-sealed tank of a coke oven gas diffusion torch system.
Background
In the prior art, in a coke oven gas diffusing torch system, a control system automatically operates, and when the pipe network pressure is too high (more than 7.8 KPa), the control system automatically opens a diffusing regulating valve 12 and the like to perform ignition diffusing. However, when the automatic control system fails, once the system pressure is too high, the blow-off valve cannot be opened, and coke oven production is affected. Vertical water sealed tank (phi 1820 is 7765 mm), tank body interface includes blow-off gas inlet pipe 13, blow-off gas outlet 2, water supply port 15 and overflow port 7, nitrogen scavenging port 3 and drain 6, see figure 2. The liquid level in the tank is set according to the gas diffusing pressure, when the gas pressure reaches a set value, the control system opens the electric diffusing valve, the gas enters the vertical water-sealed tank through the gas diffusing pipe 16 to break down the water seal, and the gas is diffused through the diffusing gas outlet 2 to ignite. When the control system fails, the system diffusion regulating valve 12 cannot be opened, and the gas pressure is too high, so that the production of the coke oven system is affected. In consideration of the factors, by utilizing the system neutral type water sealed tank, a coal gas accident diffusing interface is added on the vertical type water sealed tank body, and when an automatic control system fails, the coke oven coal gas can be automatically diffused through the water sealing depth of the accident diffusing interface, so that the safe and stable operation of the system is ensured.
Disclosure of Invention
The utility model aims to provide a vertical water-sealed tank of a coke oven gas diffusing torch system, aiming at the defects. By adding a gas diffusing interface on the vertical water sealed tank of the system and setting the water seal height of the interface, when the control system fails, the gas system can still be reliably diffused, and the safe and stable operation of the production system is ensured.
The technical scheme of the utility model is as follows: the vertical water-sealed tank of coke oven gas diffusion torch system includes tank body, the side of the tank body is equipped with diffusion gas inlet pipeline, the top of the tank body is equipped with diffusion gas outlet, the lower portion of the tank body is equipped with overflow mouth and drain outlet.
In the above scheme, the method further comprises:
the accident gas diffusing pipe is inserted into the tank body by 1200mm below the liquid level.
The accident gas diffusing pipe outside the tank body is provided with a gate valve and a diffusing pipe connecting flange.
The utility model has the advantages that: 1. the gas diffusing interface is additionally arranged between the diffusing gas inlet pipeline and the diffusing regulating valve and is connected with the accident gas diffusing pipe, the accident gas diffusing pipe is connected to the position below the liquid level in the water-sealed tank body, so that the system gas can be effectively diffused when the automatic control fails in operation, the pressure of a pipe network is reduced, and the normal operation of the gas system is ensured. 2. Reasonable structure and safe use.
Embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.

Fig. 2 is a schematic diagram of the structure of the vertical water sealed tank before improvement.
Detailed Description
Referring to fig. 1, the part names are as follows: the device comprises a pipeline connecting flange 1, a diffused gas outlet 2, a nitrogen cleaning port 3, a pressure gauge connector 4, a manhole 5, a sewage drain 6, an overflow port 7, a tank body 8, an accident gas diffusing pipe 9, a gate valve 10, a diffusing pipe pipeline connecting flange 11, a diffusing regulating valve 12, a diffused gas inlet pipeline 13, a gas diffusing gas connector 14, a water supply port 15 and a gas diffusing pipe 16.
Referring to fig. 1, the vertical water-sealed tank of the coke oven gas diffusing torch system comprises a tank body 8, wherein a diffusing gas inlet pipeline 13 is arranged on the side surface of the tank body 8, a diffusing gas outlet 2 is arranged on the top of the tank body 8, and an overflow port 7 and a sewage outlet 6 are arranged at the lower part of the tank body 8. A gas diffusing gas interface 14 is added on the diffusing gas inlet pipeline 13, the gas diffusing gas interface 14 is connected with the accident gas diffusing pipe 9, and the accident gas diffusing pipe 9 is provided with a gate valve 10 and a diffusing pipe pipeline connecting flange 11. The accident gas diffusing pipe 9 is connected into the water sealed tank body 8 and inserted 1200mm below the liquid level, and the diffused gas is led into the tank body 8 from the front of the diffusing regulating valve 12.
When the control system operates normally, the pressure of the gas reaches 7.8KPa, the system automatically opens the diffusing regulating valve 12, and the gas breaks through a water seal to perform gas diffusing ignition. Once the control system fails, the gas can be ensured to pass through the newly connected gas diffusing gas interface 14 to break down the water seal and diffuse the gas when the gas pressure reaches 12KPa, so that the system is ensured to operate in a stable pressure range.
In the original coke oven gas diffusing ignition system, the diffusing regulating valve 12 is automatically controlled by the system pressure to open the diffusing system gas, so that the pressure of the gas system is reduced, and the stable pressure operation of the system is ensured. Considering that the automatic control system may fail, the discharge of the diffused gas cannot be guaranteed at the moment, and the pressure of the pipe network is increased to influence the operation of the system. By utilizing the water seal principle, a gas diffusing gas interface 14 is added on a diffusing gas inlet pipeline 13 and is connected with an accident gas diffusing pipe 9, then the accident gas diffusing pipe 9 is connected into a water seal tank, the depth (1200 mm) of the pipeline inserted into water is set according to the system operation pressure data, when an automatic control system fails and the pressure of a gas pipe network exceeds 12KPa, the gas breaks down the water seal, and the purposes of accident diffusing pressure relief and pressure stabilizing operation of the gas pipe network are achieved.
The above description is only of specific embodiments of the present utility model, and the various illustrations do not limit the essential content of the present utility model.
