Embodiment Construction
[0031] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0032] The decompression device according to the embodiment of the present invention, such as figure 1 As shown, it includes: a decompression chamber 10, an impeller 20 and a generator 30, one end of the decompression chamber 10 has a high-pressure medium inlet, and the other end of the decompression chamber 10 has a low-pressure medium outlet; the impeller 20 is at least one stage, The impeller 20 is rotatably arranged in the decompression chamber 10; the impeller 20 is drivingly connected with the generator 30, so that the high-pressure medium drives the impeller 20 to rotate during the process of flowing from the high-pressure medium inlet of the decompression chamber 10 to the low-pressure ...

The invention provides a decompression device and a decompression system provided with the same. The decompression device comprises a decompression cavity, impellers and a generator, wherein one end of the decompression cavity is provided with a high pressure medium inlet, and the other end of the decompression cavity is provided with a low pressure medium outlet; at least first-stage impellers are arranged in the decompression cavity in a rotary mode; the impellers are in driving connection with the generator, during the process during which the high pressure medium flows from the high pressure medium inlet of the decompression cavity to the low pressure medium outlet, the impellers rotate to drive the generator to generator power. Thus, in the process of producing intermediate products and final products in petrochemical, coal oil, coal olefin and coal methanol projects, a condition of converting high pressure to low pressure can be met to acquire a safer operation environment, and besides, the energy can be converted to electric power during the conversion process, energy wastes can be avoided, and the problem of system energy wastes caused by adopting a decompression valve for decompression in the prior art can be solved.
Description
technical field [0001] The invention relates to the field of energy recovery equipment, in particular to a decompression device and a decompression system having the same. Background technique [0002] In petrochemical, coal-to-oil, coal-to-olefins and coal-to-methanol projects, the main production units (such as coal direct liquefaction unit, hydrogenation stabilization unit, hydrogenation upgrading unit, purification unit, methanol synthesis unit, etc.) are mainly It consists of a series of high temperature and high pressure process equipment. [0003] The high-pressure condition in the process system is partly contributed by the volume expansion of the gas produced by the system medium during the reaction process, and the other part is formed by consuming external energy (electricity, steam, etc.) to increase the pressure of the system medium. [0004] In the process of producing intermediate products and final products, it is necessary to convert high-pressure condition...
