Humidification method of eddy flow spray and humidification tower

Abstract

A wetting method by spiral-flow atomizing includes leading low temperature air to bottom of wetting tower in counter-flow uniform mode, spraying high temperature water from top down to bottom then discharging said water out after it is heat and mass transferred with said low temperature air counter-flow forming air flow film at periphery of scattered water drop in said heat and mass transfer course then removing off small water drop rising-up in following air flow for finalizing the dewatering or deatomizing process. The wetting tower used for realizing said method is also disclosed.

Description

technical field [0001] The invention belongs to the technical field of humidification of gas turbine devices, and in particular relates to a swirl spray humidification method. [0002] The invention also relates to a humidification tower for carrying out the above method. Background technique [0003] High-pressure air humidification technology is an important means to improve the performance of gas turbines. Under the current gas turbine parameters, the working pressure of the high-pressure humidification tower can reach 40bar, and the working temperature can reach 150-250°C. For the humidification process under such harsh conditions, the humidification devices commonly used in the chemical industry cannot meet the requirements. [0004] The existing high-pressure air humidification technology uses a device in the form of a packed tower. Under high temperature and high pressure conditions, ordinary packing is difficult to meet the requirements, and stainless steel structur...

AI Technical Summary

Problems solved by technology

The use of metal packing increases the thermal inertia of the humidification tower. When the gas turbine device is operated under variable conditions, the increase in thermal inertia will lead to a longer response time of the gas turbine system, which is not conducive to the variable condition operation of the system.

[0005] The resistance loss caused by the packing is the main source of the resistance of the packing tower humidification device. Excessive pressure loss will cause a decrease in the specific work and efficiency of the gas turbine device

There are also problems with the uniformity of water distribution or wetting of the filler. When the system load is small, the water flow into the humidification tower will decrease, which will make the surface of the filler unable to be completely wetted, thereby reducing the interphase contact area between gas and liquid. , not conducive to heat and mass transfer
