Abstract

The invention provides an integrated spray flue gas waste heat recovery and denitration device. The device comprises a spray filler and alkali storage tower (1), a flue gas conveying and oxidization loop system, a spray conveying loop system, a heat energy utilization system and an alkalifying neutralization system, wherein the spray filler and alkali storage tower (1) comprises a spray filler and alkali storage tower main body structure part (11), a spray filler and alkali storage tower connector, filler (13), a dehydrator (14) and a spray component (15). According to the device, spray water is in contact with flue gas for heat exchange through the filler with a large specific surface area, the stable contact heat exchange area of gas and liquid phases is remarkably increased, the contact time of gas and liquid phases is remarkably prolonged and the uniformity of gas and liquid phases is remarkably improved, and the performance and the stability of gas liquid heat exchange are remarkably improved, so that the flue gas waste heat recovery efficiency and the denitration/desulfurization effect are remarkably improved.

Description

technical field [0001] The invention relates to a spray flue gas waste heat recovery and denitrification integrated device, in particular to a spray flue gas waste heat recovery and denitrification integrated device for natural gas boilers. Background technique [0002] The efficiency of natural gas boilers can reach about 90%. However, due to the high price of natural gas (about 1.5 times that of light oil and 5 times that of coal), how to further improve the efficiency of natural gas boilers is still very important, and the existing boiler design technology Reducing the exhaust heat loss is the main factor to improve the efficiency of the boiler, so how to recover the sensible heat and latent heat in the waste heat of the flue gas is the key to further improve the efficiency of the gas-fired boiler. For the heat exchange equipment of the flue gas recovery device of the existing empty tower spray and flue gas direct contact heat exchange, the cooling water is sprayed into f...
