Description

Technical Field

[0001] This utility model belongs to the field of gas valve technology, specifically relating to a water-sealed venting isolation system. Background Technology

[0002] When the gasifier is first ignited, a large amount of exhaust gas needs to be released. After the situation returns to normal, the release valve should be closed. In the event of a sudden production accident, the release valve should also be opened quickly and closed after the situation returns to normal.

[0003] In existing technology, the vent pipe is closed using a traditional disc valve, which involves pulling up a flat iron plate to block the circular opening of the vent pipe and using mud and sand for auxiliary sealing. The drawbacks are that the vent opening is not completely sealed, and it is time-consuming and labor-intensive. Due to the long-term passage of gas, the coal tar contained in the gas will gradually seal the iron plate of the disc valve tightly. However, in an emergency requiring urgent gas release, this iron plate, due to the thick layer of coal tar, requires a sledgehammer to break it open, steam to remove it, and a significant amount of time, manpower, and resources. Furthermore, it cannot quickly and effectively open the vent opening to eliminate potential hazards in sudden situations. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a water-sealed venting isolation system that is simple to operate, can be opened and closed tightly at any time, and can be quickly vented in the event of an emergency in production.

[0005] The technical solution adopted by this utility model is a water-sealed venting isolation system, which includes a venting cavity, a sealing cavity and a gas pipeline cavity connected sequentially from top to bottom. A water inlet pipe, a pressure balance pipe and an overflow outlet pipe are connected sequentially from top to bottom on the outside of the sealing cavity. A transmission wheel and an auxiliary wheel are arranged sequentially from left to right at the top of the sealing cavity. The outlet end of the gas pipeline cavity is located inside the sealing cavity.

[0006] The present invention is further characterized in that,

[0007] The sealing cavity includes a first sealing cavity and a second sealing cavity. The first sealing cavity and the second sealing cavity have a stepped overflow structure. A heat tracing pipeline is provided on the outer wall of the second sealing cavity.

[0008] The end of the water inlet pipe away from the sealing cavity is connected to a first water inlet pipe and a second water inlet pipe, and the overflow pipe is a Venturi tube structure.

[0009] The sealed cavity is also provided with a concave sealing cover, and the top lead of the concave sealing cover is connected to a counterweight block through a transmission wheel and an auxiliary wheel in sequence.

[0010] A water level sensor is installed on the outer wall of the portion of the gas pipe cavity located inside the sealed cavity.

[0011] The beneficial effects of this utility model are:

[0012] (1) The water level sensor at the outlet of the gas pipeline in the water-sealed venting isolation system of this utility model can accurately detect the water seal liquid level and realize automatic water replenishment or overflow control through data feedback to prevent gas from escaping due to insufficient liquid level. When the water level is lower than the preset safety value, the system can trigger an alarm or link to close the valve to avoid major safety hazards. It is suitable for high-risk gas transportation scenarios.

[0013] (2) The overflow pipe of the water seal type venting isolation system of this utility model adopts a Venturi tube structure, which utilizes the principle of fluid dynamics to increase the overflow speed, prevent impurities from accumulating and clogging, and at the same time reduce the frequency of water seal liquid replenishment.

[0014] (3) In the water-sealed venting isolation system of this utility model, the pressure balance pipe is linked with the water inlet pipe and the overflow pipe to dynamically adjust the air pressure in the sealing cavity, avoid water seal failure due to pressure fluctuation, enhance system stability, and the heat tracing pipeline on the outer wall of the second sealing cavity can prevent the water seal liquid from freezing in low temperature environment, ensuring reliable operation of the system in extreme climate.

[0015] (4) The water-sealed venting isolation system of this utility model forms a double water seal barrier through the stepped design of the first sealing cavity and the second sealing cavity, which significantly improves the sealing performance of the gas in the gas pipeline and prevents the leakage of harmful gases.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0019] like Figure 1As shown, this utility model discloses a water-sealed venting isolation system, comprising a venting chamber 1, a sealing chamber 2, and a gas pipe chamber 3 connected sequentially from top to bottom. The venting chamber 1 is used to vent gas when the gas furnace is first ignited or in the event of a sudden production accident to prevent gas explosions and other accidents. The sealing chamber 2 is used to seal the gas in the gas pipe chamber 3 to prevent the gas from being trapped and causing environmental problems. The gas furnace is connected to the bottom of the gas pipe chamber 3. A water inlet pipe 4, a pressure balancing pipe 5, and an overflow pipe 6 are connected sequentially from top to bottom on the outside of the sealing chamber 2. The water inlet pipe 4 is used to inject water into the sealing chamber to achieve a water seal effect. The pressure balancing pipe 5 is linked with the overflow pipe 6 to dynamically adjust the gas pressure in the sealing chamber 2 to avoid water seal failure due to pressure fluctuations. A transmission wheel 7 and an auxiliary wheel 8 are arranged sequentially from left to right at the top of the sealing chamber 2. The outlet end of the gas pipe chamber 3 is located inside the sealing chamber 2.

[0020] The sealing cavity 2 includes a first sealing cavity 201 and a second sealing cavity 202. The first sealing cavity 201 and the second sealing cavity 202 have a stepped overflow structure. The outer wall of the second sealing cavity 202 is provided with a heat tracing pipeline. The heat tracing pipeline uses a high-temperature resistant silicone electric heating film linked with a temperature controller. When the ambient temperature is lower than 5°C, heating is automatically started to prevent the water seal from freezing and failing.

[0021] A spiral guide plate can also be installed inside the second sealing cavity 202 to prevent excessive impact force from affecting the sealing effect during water replenishment, and at the same time increase the gas-liquid separation efficiency to prevent the pipeline from being blocked.

[0022] The end of the water inlet pipe 4 away from the sealing cavity 2 is connected to a first water inlet pipe 401 and a second water inlet pipe 402. The first water inlet pipe 401 is connected to a high-pressure water supply device, and the second water inlet pipe 402 is connected to a conventional water supply device. The overflow pipe 6 is a Venturi tube structure. The overflow pipe 6 with the Venturi tube structure, together with the pressure balance pipe 5, can perform negative pressure compensation to maintain system stability.

[0023] The sealed cavity 2 is also provided with a concave sealing cover 203. The outlet end of the gas pipe cavity 3 is located in the sealed cavity 2, so the sealing cover is concave in shape. Both the inner and outer sides of the concave sealing cover 203 are filled with water. The water on both sides will achieve water sealing of the gas pipe cavity 3 by the concave sealing cover 203. The lead wire at the top of the concave sealing cover 203 is connected to the counterweight block 9 through the transmission wheel 7 and the auxiliary wheel 8 in sequence.

[0024] The top lead of the concave sealing cover 203 can also be connected to a drive motor via the transmission wheel 7 and the auxiliary wheel 8 in sequence. This reduces manual operation, enhances automation capabilities, and allows for immediate operation.

[0025] A water level sensor 301 is installed on the outer wall of the gas pipe cavity 3 located inside the sealing cavity 2. The water level sensor 301 is used to send water level data in real time. When water sealing is performed, a conventional water replenishment device is used to replenish water for sealing. If the water level has not reached the preset level within a predetermined time, a high-pressure water replenishment device is activated to quickly replenish water for sealing.

[0026] Working principle: When sealing the gas pipeline 3, water is injected into the sealing cavity 2 through the water inlet pipe 4. The water level difference forms a liquid seal barrier, blocking the gas passage. When the water level reaches the height of the overflow pipe 6, excess water is discharged. This, combined with the pressure balancing pipe 5, maintains a constant sealing pressure. The sealing cavity 2 uses a two-stage sealing method, adaptable to sealing requirements under different pressure conditions, while reducing pipe blockage. The water level sensor 301 is electrically connected to a control terminal. When the water level is detected to be lower than the preset level, the water inlet pipe 4 automatically opens to replenish water. If the water level does not reach the preset level within a predetermined time, the high-pressure water replenishment device is activated for rapid replenishment. The second sealing cavity 202 is sealed with water, and a heat tracing pipeline is provided on the outer wall of the second sealing cavity 202. The heat tracing pipeline uses a high-temperature resistant silicone electric heating film linked with a temperature controller. The temperature controller is electrically connected to a control terminal. When the ambient temperature is below 5°C, heating is automatically started to prevent the water seal from freezing and failing. When a gas venting operation is required, the counterweight 9 is manually lifted or the concave sealing cover 203 is lifted using a drive motor. At this time, the seal fails, and the gas in the gas pipe cavity 3 is vented through the venting pipe cavity 1. This utility model provides a water-sealed venting isolation system with a tight seal. The time required for both venting and sealing operations is short, saving manpower and resources.
