Embodiment Construction

[0021] attached figure 1 A specific embodiment is a multi-stage air pressurized water machine driven by low-pressure industrial tail gas. The low-pressure industrial exhaust gas enters the exhaust gas purification device 1 through the pipeline to remove solid or liquid substances, and then enters the voltage stabilizing device 2 through the pipeline. The low-pressure exhaust gas discharged from the voltage stabilizing device 2 enters through the pipeline 6 and drives the first-stage air pressure water press 3 and the second-stage respectively. Air pressure water press 4, three-stage air pressure water press 5, the water in the pool 12 enters the first-level air pressure water press 3 through the water inlet pipe 7, and then continuously enters the second-level air pressure water press 4 through the upper water pipe 8 under air pressure , and enter the three-stage air pressure water press 5 through the upper water pipe 9 under the air pressure, and finally discharge through the...

Abstract

The invention relates to a utilization method of pressure energy in low-pressure industrial exhaust gas. According to the method, a pneumatic water pump is driven by the low-pressure industrial exhaust gas to lift water to a high place so as to replace an electric water pump or store the water for power generation. The method has the advantages that complex mechanical operation and more energy conversion loss are avoided in a whole energy recovery system, project construction cost is reduced, operation is flexible, and efficiency of energy recovery is improved; the pressure of exhaust gas can be converted into water lift as much as possible, by the pneumatic water pump, and accordingly recovering the energy in ultralow-pressure industrial exhaust gas is made possible.

Description

Technical field: [0001] The invention relates to a method for recycling the pressure energy of low-pressure industrial tail gas. technical background: [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 industrial tail gas greater than 0.4Mpa can be recovered through a turbine; the conditions for energy recovery of industrial tail gas with a relatively small pressure through a turbine often require a large flow rate, coupled with large-scale and high-cost construction , in order to achieve a higher utilization efficiency; but for the venting of industrial tail gas with lower pressure, such as the venting of 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 is low, and on the other hand, the construction cost is too high. [0003] At ...
