Embodiment 1
[0027] Such as figure 1 As shown, a CCPP system bypass gas temperature reduction and pressure reduction and waste heat recovery equipment includes a base 19, an equipment shell 16 above the base 19, and a gas pipeline 2. The top of the equipment shell 16 is provided with a gas outlet 15, which The lower part is a sump 8, and the outer side of the sump 8 is connected with a hot water pipe 10; above the sump 8, a diffusion pipe 6 is arranged; a gas channel 20 is formed between the diffusion pipe 6 and the equipment casing 16, and a Mist eliminator 7, the bottom end of this diffuser pipe 6 communicates with sump 8 and gas channel 20 respectively; Described gas pipe 2 enters equipment shell 16 from the bottom end of equipment shell 16 and extends in the diffuser pipe 6, and it is in One end outside the equipment shell 16 has a gas pipeline inlet 1, and a number of decompression orifice plates 3 are arranged in the pipe, and the decompression orifice plate 3 here can be a porous de...
Embodiment 2
[0035] Such as figure 1 As shown, on the basis of Example 1, the gas pipeline 2 and the diffusion pipeline 6 are made of anti-corrosion materials, which can effectively prevent gas and impurities from corroding each pipeline and affecting the normal operation of the equipment.
Embodiment 3
[0037] Such as figure 1 As shown, the walls of gas pipeline 2 and diffusion pipeline 6 described in Example 1 are all provided with anti-corrosion coatings, which can effectively prevent gas and impurities from corroding each pipeline and affect the normal operation of the equipment.
