A Closed Circulation System for Improving Operation Efficiency of Gas Drain Pump

Abstract

The invention discloses a closed circulation system for improving the operating efficiency of a gas drainage pump. The liquid inlet of a pneumatic diaphragm pump is connected with the liquid outlet of a polymer drag-reducing solution tank, and the liquid pipe of the pneumatic diaphragm pump leads into a circulating water pool. A pneumatic agitator is arranged inside the polymer drag reducing solution tank, and a feeding funnel is arranged on the top. The liquid outlet of the submersible pump is respectively connected with the liquid inlet of the polymer drag reducing solution tank and the liquid inlet of the gas drainage pump through a tee, and the discharge pipe of the gas drainage pump is connected to the circulating pool. The high-speed operation of the pneumatic agitator and the pneumatic diaphragm pump is used to mix the polymer drag-reducing solution evenly and send it into the circulating pool. At the same time, the outlet pipe of the submersible pump supplies water to the polymer drag-reducing solution tank, and the polymer drag-reducing solution is added through the feeding funnel. agent to realize the continuous dosing of drag reducing solution, ready to use. The gas drainage pump uses polymer drag reducing solution as the working medium, which can greatly improve the operating efficiency of the gas drainage pump. The system is simple in structure, easy to operate, and realizes a closed cycle of drag reducing solution supply.

Description

technical field [0001] The invention relates to a closed circulation system for improving the operation efficiency of a gas drainage pump, and is especially suitable for the gas drainage system of a mobile pumping station in a coal mine. Background technique [0002] "Coal Mine Gas Drainage Engineering Design Specifications" stipulates that high-gas mines or mines mining dangerous coal seams with coal and gas outbursts must establish a gas drainage system. As the power source of the gas drainage system, the gas drainage pump plays an important role in the efficient and safe production of the mine. However, the gas drainage pump has low operating efficiency and high energy consumption. The actual efficiency is only 10-40%, but it accounts for 1 / 4 of the total electricity consumption of coal mines. This problem is extremely incompatible with the country's requirements for energy conservation and emission reduction in coal mines and my country's current energy shortage. [00...

AI Technical Summary

Problems solved by technology

However, the polymer drag reducer for mining has poor solubility and a large amount, and it needs to be fully stirred to achieve a good drag reduction effect, and it needs to be added quantitatively and regularly

The existing device cannot be fully connected with the coal mine underground pumping station system, and cannot realize the continuous dosing of the drag reducing agent and the requirements of ready-to-use, resulting in cumbersome working procedures and high consumption of manpower and material resources, which is not conducive to the popularization and application of this technology
