Problems solved by technology

Most of these treatment methods are based on the chemical composition or the cause of the crystalline substance. The treatment principle is single and the cost is high. None of them can effectively treat the precipitated crystalline substance in a long-term and green way.

Abstract

The invention relates to a green system and method for removing grown-up karst tunnel draining pipeline crystals and belongs to the technical field of tunnel engineering. The system comprises a CO2 purifying device composed of a pressure swing adsorption device (PSA device) and a CO2 collecting tank, and a refrigerating device composed of a water storage water tank and a refrigerator. The bottom of the water storage water tank is connected with a water pump and the CO2 collecting tank, and the upper portion of the water storage water tank is connected with a center ditch through a water levelcontrol valve. The water pump is connected with a longitudinal water draining pipe on one side of the interior of a water draining zone through a connecting three-way joint, a transverse water draining pipe on the side of the interior of the water draining zone is connected with an intelligent valve, and a transverse water draining pipe on the other side of the water draining zone keeps the normalwater draining state. By means of the green system and method for removing grown-up karst tunnel draining pipeline crystals, the crystal problem of a water draining system can be solved greenly, in addition, CO2 waste gas in a tunnel and tunnel drained water can be effectively utilized, self marketing of CO2 gas in the karst tunnel is achieved, and a new application direction is also provided forautomobile tail gas treatment and karst tunnel water resource utilization.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering and relates to a green system and method for removing the crystallization of drainage pipes of long karst tunnels. Background technique [0002] The normal operation of the drainage system in the tunnel is one of the important links to ensure the normal operation of the tunnel. However, during the construction and operation of the tunnel, the phenomenon of crystallization and blockage of the drainage system is generally prone to occur. Blockage of drainage pipes by crystals will lead to a series of problems affecting the appearance and normal operation of the tunnel, such as poor local drainage, increased water pressure outside the lining, cracking of the lining support structure, water seepage and leakage in the tunnel, and water accumulation on the road. Therefore, how to remove the crystallization of tunnel drainage pipes to ensure the smooth drainage system has become the focus of a...
