Meet heat exchanger A passage B；Described passage B outlet is connected to heat exchanger B channel C by pipeline G, and described channel C is led to
Pipeline H connection burners are crossed, by pipeline K connection denitrification apparatus, the outlet of described denitrification apparatus passes through described burner
Pipeline M connection heat exchangers B passage D, described passage D outlet ports are equipped with discharge pipe.
The described heat exchange structure applied to steel mill, described heat exchange structure include heat exchanger, and described heat exchanger has
Outer cover of heat exchanger, the inner upper end of described outer cover of heat exchanger are fixed with transmission gear ring, described transmission gear ring and transmission device
Engagement connection, described transmission device are fixed on the upper surface of upper head plate, and described upper head plate with bottom plate changing respectively by welding equipment
On hot device shell, the centre position of described upper head plate and bottom plate has center shaft device, described center shaft device and one
Connection is hung in the fan-shaped storehouse of group by bearing pin respectively, described fan-shaped storehouse be circumferentially uniformly distributed and with center shaft device and meanwhile turn
It is dynamic, there is multigroup heat transfer element in described fan-shaped storehouse.
The beneficial effects of the utility model：
1. the utility model structure setting is reasonable, desulphurization system can be allowed to be in respective nearest operating temperature with denitrating system
Section, the heat in flue gas is made full use of, under conditions of desulphurization and denitration temperature is met, at utmost utilize flue gas itself heat
Amount, system thermal input is reduced, without unnecessary loss, is increased operation rate, increases economic benefit, serves energy-saving work
With.
Multigroup thousands of high duty heat transfer component is enclosed in fan-shaped storehouse of the present utility model, can be effectively by cigarette
Gas heat shifts, and avoids flue gas heat from wasting, improves the efficiency and energy-conserving action of each equipment, and there is efficient heat exchange to imitate for it
Rate, small volume, in light weight, maintenance, replacing convenience.
