Background
The strong national strategy of traffic drives the great development of tunnel construction in China, toxic and harmful gas strata rich in gas and the like inevitably pass through, the water-vapor mixture rich in harmful gas such as gas and the like at the back of the lining during the operation of the tunnels needs to be separated by a water-vapor separation device and then discharged, the gas is led to a high place outside a tunnel portal through a pipeline to be discharged, underground water flows into a drainage system to be discharged, at the moment, a water-vapor separation bin embedded in a transverse channel between a main tunnel and a flat guide room is undoubtedly a good choice, the design idea of the water-vapor separation bin is to discharge the gas by opening a hole at the upper part of the device, discharge the liquid by opening a hole at the lower part of the device, and simultaneously, the harmful gas retained at the upper part of the device after being separated by a liquid sealing device at. However, in practice, when the underground water quantity is not abundant or the underground water is dried due to seasonal influences, the liquid at the lower part of the device can not play a role in sealing harmful gas after being evaporated and dried, so that the harmful gas overflowing from the back of the tunnel lining can be diffused into the tunnel through the drainage system, and the operation safety of the gas tunnel is threatened.
Disclosure of Invention
The invention aims to solve the technical problem of providing a separation bin with a gas seal device for underground water and harmful gas, so as to ensure that the gas in the separation bin does not leak under the condition of water shortage or no water in the separation bin, and prevent the harmful gas from overflowing and scattering into a tunnel through a drainage system, thereby ensuring the operation safety of a gas tunnel.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the invention relates to an underground water and harmful gas separation bin with a gas seal device, which is characterized in that: the device comprises a separation bin, a water body storage and discharge bin and a bin body, wherein the upper part of the separation bin is provided with a liquid inlet pipe for accessing a water-steam mixture and a gas outlet pipe for discharging separated gas, and the middle part of the water body storage and discharge bin is provided with a water outlet pipe for discharging separated underground water; the separation bin is communicated with the water storage and discharge bin through a water outlet, and an air sealing device which is controlled by the liquid level in the separation bin and enables the water outlet to be switched between a communicated state and a blocked state is arranged.
The air sealing device is composed of a floating ball, an air sealing plug, a stranded wire and a pulley block, wherein the floating ball is arranged in the separation bin, the air sealing plug is positioned in the water body storage and discharge bin and is positioned at the water outlet, the pulley block is fixedly arranged on the top wall of the separation bin, the stranded wire bypasses the pulley block, and the two ends of the stranded wire are respectively connected with the floating ball and the air sealing plug.
The gas seal device is controlled by the liquid level in the separation bin and enables the water outlet to be switched between a communicated state and a blocked state, so that gas in the separation bin is prevented from leaking under the condition of water shortage or no water in the separation bin, harmful gas is prevented from overflowing into the tunnel through a drainage system, the problem of separation and discharge of a water-steam mixture is effectively solved, the problems that the water seal cannot be realized by the separation device and the like caused by factors such as underground water level reduction and seasonal variation are also considered, and the operation safety of the gas tunnel is ensured; the drainage effect can be ensured, the gas sealing is also considered, and the effect is exact; simple structure, economy is suitable for, and the size is adjustable, can prefabricate also can the cast in situ.
Drawings
The specification includes the following three drawings:
FIG. 1 is a perspective view of a groundwater and harmful gas separation bin with a gas seal device according to the present invention;
FIG. 2 is a perspective sectional view of an underground water and harmful gas separation chamber with a gas seal device according to the present invention;
FIG. 3 is a perspective sectional view of a groundwater and harmful gas separation bin with a gas seal device according to the present invention.
The figures show the components and corresponding references: the device comprises a separation bin 1, a vertical partition plate 1a, a transverse partition plate 1b, a liquid inlet pipe 2, a water body storage and discharge bin 3, a water level gauge 4, a floating ball 5, a water outlet pipe 6, an air sealing plug 7, a stranded wire 9, a pulley block 8, a water outlet 10 and a gas outlet pipe 11.
Detailed Description
The invention is further illustrated with reference to the following figures and examples.
Referring to fig. 1 to 3, the underground water and harmful gas separation bin with the air seal device of the invention comprises a separation bin 1, a water body storage and discharge bin 3 and a bin body, wherein the upper part of the separation bin 1 is provided with a water inlet pipe 2 for accessing a water-steam mixture and an air outlet pipe 11 for discharging separated gas, and the middle part of the water body storage and discharge bin 3 is provided with a water outlet pipe 6 for discharging separated underground water. The gas seal device that is linked together through delivery port 10 between separation storehouse 1 and water storage and discharge storehouse 3, and set up by the messenger delivery port 10 of liquid level control in the separation storehouse 1 in the intercommunication, the separation carries out the conversion between two kinds of states, guarantee under the state of lack of water or anhydrous in the separation storehouse 1 that the storehouse is internal gas not to leak, avoid harmful gas to pass through drainage system and spill to the tunnel inside, the effectual separation emission problem of the steam mixture of having solved, still compromise the unable water seal scheduling problem that realizes of separator that factors such as groundwater level decline and seasonal change caused, thereby ensure the operation safety in gas tunnel, can guarantee the drainage effect, compromise gas again and seal, the effect is definite.
