Embodiment 1

[0037]The integrated residual pressure recovery device in the present invention mainly uses a turbine to recover the residual pressure of nitric acid tail gas, directly drives the nitrogen oxide compressor, and adopts a high-speed machine to make the device body small and light, and the integrated machine can simplify the system and structure . Nitrogen oxide and other mixed gases are poisonous and corrosive, so they cannot leak. This integrated residual pressure recovery device uses carbon rings to seal 8 process gases, and adds a third gas for isolation. In addition, it is necessary to prevent the process gas from entering the oil system, otherwise it will pollute the oil quality; use honeycomb seals to seal 9 oils, because the lubricating oil in the nitric acid industry cannot enter the nitrogen oxide gas, otherwise it will cause an explosion; the strict sealing system is an integrated residual pressure One of the key technical problems to be solved by the recovery device. ...

Abstract

The invention discloses an integrated residual pressure recovery device. The integrated residual pressure recovery device comprises a compression end, an intermediate body and an expansion end which are connected in sequence. A spindle is mounted in the intermediate body and penetrates through a compression end impeller and an expansion end impeller. The expansion end comprises a gas inlet channel, an expansion end volute, an expansion end nozzle and the expansion end impeller mounted on the spindle. The compression end comprises a gas inlet channel, the compression end impeller mounted on thespindle, a pressure expander and an expansion end volute. The integrated residual pressure recovery device provided by the invention can effectively recover and convert available energy in tail gas and recovers residual energy in the tail gas through the expansion end, that is, nitric acid tail gas does work through the expansion end impeller. Pressure energy of the tail gas is converted into mechanical energy to drive the compression end impeller to pressurize process gas. The integrated residual pressure recovery device can recover the residual energy in the nitric acid tail gas and compress the process gas and has remarkable economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of residual pressure recovery, in particular to an integrated residual pressure recovery device. Background technique [0002] At present, in the face of the tense situation of the world's energy situation, domestic and foreign countries have been researching alternative new energy sources, and at the same time, energy recovery and utilization are also carried out in the process of energy conservation and emission reduction. The so-called residual pressure and heat recovery refers to the excess pressure differential energy released by enterprises in the production process, which can be recycled under certain conditions. The recovery of waste heat and pressure mainly comes from high-pressure and high-temperature gases, and the recovery of waste heat and pressure is mainly used in industries such as iron and steel, coal, building materials, chemicals, textiles, and metallurgy. [0003] At present, waste heat ...
