Problems solved by technology

[0006] However, the high-efficiency cooling and pressure reducing device of the CXD series water vapor sampling rack adopts a water cooling method, which is mainly for cooling and supplemented by reducing pressure. Even two stages connected in series cannot be used for water vapor sampling of ultra-supercritical generator sets

Embodiment 1

[0034] Embodiment 1: With reference to Fig. 2, the ultra-supercritical generator set self-regulating water vapor sampling rack, the first high temperature and high pressure valve 1a installed on the main road is connected with the water sample inlet of the rod filter 3, the water sample of the rod filter 3 The outlet is connected to the second high temperature and high pressure valve 1b, the waste water outlet of the rod filter 3 is connected to the high temperature and high pressure drain valve 1c, the second high temperature and high pressure valve 1b is connected to the water sample inlet of the air-cooled pre-cooling pressure reducer 5, and the air cooling The water sample outlet of the formula pre-cooling and pressure reducing device 5 is connected with the water sample inlet of the first high-efficiency cooling and pressure reducing device 2a, and the water sample outlet of the first high-efficiency cooling and pressure reducing device 2a is connected with the water sample...

Embodiment 2

[0038] Embodiment 2: refer to Figure 4 , Embodiment 2 The self-adjusting water vapor sampling frame of the ultra-supercritical generating set is basically the same as the structure of Embodiment 1, except that between the water sample outlet of the rod filter 3 and the sample inlet 10 of the air-cooled pre-cooling pressure reducer 5 The second high temperature and high pressure valve 1b is removed.

[0039] refer to Figure 5 , the self-adjusting water vapor sampling rack of the ultra-supercritical generating set has a steady-state operating characteristic curve under the stable condition of two representative water sample characteristic parameters. The first curve in the upper part of the figure, firstly, the air-cooled pre-cooling and pressure reducing device 5 uses steam to cool it, and the state changes from 620°C, 27Mpa to 500°C, 20Mpa; then the first high-efficiency cooling and pressure reducing device 2a Use cooling water to make phase change (subcritical steam into l...

Abstract

The invention relates to a super critical generator group automatic vapor sampling frame, which comprises a high temperature high pressure valve fixed on the main pipe line a, rod-type filter, performance heat pressure regulator a, performance heat pressure regulator b, and safety valve d. it is characterized in that the air cooled heat pressure pre-regulator is between the water outlet of the rod-type filter and the water outlet of the performance heat pressure regulator a; the structure of the air cooled heat pressure pre-regulator is that the air inlet is positioned on the bottom of the casing; the air outlet is positioned on the top of the casing; the helicoids sample flow pipe is positioned inside the casing; the sample inlet of the helicoids sample flow pipe is through the top air outlet of the casing; the sample outlet of the helicoids sample flow pipe is through the bottom air inlet of the casing.

Description

technical field [0001] The invention relates to a heat exchange device, which is a self-regulating water vapor sampling rack for an ultra-supercritical generating set. Background technique [0002] In the thermal power generation industry, in order to improve the efficiency of power generation equipment and reduce energy consumption, some powerful countries in the world are working hard to improve the parameters of thermal power generation units and increase the unit capacity of generating units. For example: my country is also developing 1000MW, the main steam Parameter pressure is 27MPa, temperature is 620°C, water supply pressure is 34Mpa, temperature is 310°C ultra-supercritical generator set. Some industrially developed countries such as the United States, Japan and other countries have taken units with higher parameters and larger capacities as development goals. [0003] The higher the water vapor parameters of the generator set, the higher the requirements for its wo...
