Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is further described: a kind of intelligent desulfurization equipment, by pressure swing adsorption pure oxygen machine 2, two-way heat exchanger 1, coal-fired boiler 4, centrifugal compressor 3, graded distiller 5, sulfur detector 1. The main board is composed of the control panel. The pressure swing adsorption pure oxygen machine 2 purifies oxygen from the air, enters the two-way heat exchanger 1 for heating, and then enters the coal-fired boiler 4 for combustion. After releasing heat, it then enters the two-way heat exchanger 2 to release waste heat for cooling. , and then compressed by the centrifugal compressor 3 to become a high-pressure liquid, and then enter the fractional distiller 5 for fractional distillation to separate various gas components.

[0012] Optimization scheme 1: add a low-temperature heat exchanger after compression by the centrifugal variable-frequency compressor, and then con...

Abstract

The invention provides intelligent desulfurization equipment, consisting of a pressure swing adsorption pure oxygen machine, a two-way heat exchanger, a coal-fired boiler, a multi-stage frequency conversion centrifugal compressor, a fractional distillation device, a sulfur-containing detector and a control mainboard. The pressure swing adsorption pure oxygen machine is used for purifying oxygen from air; gas enters the two-way heat exchanger to be heated and then enters the coal-fired boiler for combustion; after heat is released, the gas enters the two-way heat exchanger to release afterheat and be cooled; the gas is compressed into high-pressure liquid by the centrifugal compressor; and the high-pressure liquid enters the fractional distillation device to be subjected to fractional distillation to separate out various gas components, so that various gases can be separated by distillation, the desulfurization ratio and the denitration ratio reach 99 percent, high-purity industrial gas source can be provided, economical value is brought, and the intelligent desulfurization equipment is suitable for medium and large-sized boilers and power plants.

Description

technical field [0001] The invention relates to an environmental protection equipment, in particular to an intelligent desulfurization equipment. Background technique [0002] The current basic principle of desulfurization is to add limestone powder and water to make a slurry as an absorbent and pump it into the absorption tower to fully contact and mix with the flue gas. Calcium sulfate, when calcium sulfate reaches a certain degree of saturation, it crystallizes to form dihydrate gypsum. The gypsum slurry discharged from the absorption tower is concentrated and dehydrated to make its water content less than 10%, and then sent to the gypsum storage warehouse by a conveyor for stacking. The desulfurized flue gas passes through a demister to remove mist droplets, and then heats through a heat exchanger After heating up, it is discharged into the atmosphere through the chimney. [0003] The denitrification is basically the use of ammonia reaction to generate nitrogen. [00...
