Embodiment Construction

[0018] attached figure 1 It is a specific embodiment in which a multi-stage air pressurized water machine is driven by pressurized industrial tail gas. As shown in the figure, the pressurized industrial tail gas enters the tail gas purification device 1 through the pipeline. After removing solid or liquid substances or doing corresponding treatment, it enters the pressure stabilizing device 2 through the gas transmission pipeline 8. After the pressure is adjusted by the stabilizing device 2, it is discharged. The exhaust gas under pressure enters into and drives the primary air pressure water press 4, the secondary air pressure water press 5, and the third air pressure water press 6 respectively through the air intake pipe 10, and the water in the pool 7 enters the primary air pressure water press through the water inlet pipe 11. After the pressurized water machine 4, it continuously enters the secondary air pressurized water machine 5 through the upper water pipe 12 under the...

Abstract

The invention relates to a pressurized industrial exhaust gas energy utilization method. The method is characterized that a pipeline is communicated with a pressurized industrial exhaust gas exhausting port and an air pressure water machine, a pressure stabilizing or bypass device is arranged between the pressurized industrial exhaust gas exhausting port and the air pressure water machine, and an air distribution device is arranged. The pressurized industrial exhaust gas drives the air pressure water machine to pump water up high and replaces an electric pump or is used for water storage and power generation. The method has the advantages that according to an entire energy recycling and utilizing system, complex dynamic mechanical operation and more energy conversion loss are avoided, project cost is reduced, operation is flexible, and the energy recovering and utilizing efficiency is improved; since the air pressure water machine is capable of converting the pressure of the exhausted gas into the stoke of water to the utmost extent, and possibility is provided for recovery of industrial exhaust gas energy exhausted under extra low pressure.

Description

Technical field: [0001] The invention relates to a method for recycling the pressure energy of pressurized industrial tail gas. Background technique: [0002] An energy utilization method of pressurized industrial tail gas is to use a turbine to drive a generator or a supercharger by utilizing the expansion process of the pressurized gas. Generally, the energy of the industrial tail gas greater than 0.4MPa can be recovered through the turbine; the conditions for the energy recovery of the industrial tail gas with a lower pressure through the turbine often require that the tail gas has a higher temperature and a larger concentration of the exhaust gas. Higher utilization efficiency can only be achieved if the flow rate is combined with large-scale and high-cost construction; but for the venting of industrial tail gas with lower pressure, such as industrial tail gas with a pressure below 0.1MPa, it is difficult for the turbine to play a role. On the one hand, the efficiency i...
