Detailed Description
Example one
The structure of the high-temperature resistance type air heater of the embodiment is shown in fig. 1-3, the whole channel shell of the device is a cuboid, channel steel or angle steel is adopted as a framework 3 and a base 4, a lining 310S radiation-proof plate 5 is arranged, two ends of a high-temperature-resistant corundum tube 7 are fixed on framework beams at two sides, and the length of the corundum tube is determined according to the power of a resistance wire (belt) 13 wound by each corundum tube (see fig. 3 for the structure details); the number of the corundum tubes 7 is determined according to the total power of the equipment and three-phase grouping connection. The periphery of the channel shell framework is insulated by adopting composite aluminum silicate and the insulation board 6, so that the equipment is prevented from causing heat loss due to high-temperature operation. Be equipped with gas inlet 1 and gas outlet 2 respectively at equipment passageway casing both ends, be converted into heat energy by electric energy after circular telegram resistance wire (area), process gas takes the heat that resistance wire (area) distribute out to equipment gas outlet 2 by equipment gas inlet 1 under the effect of fan to satisfy process temperature and can reach about 1150 ℃, and have overtemperature prote alarming function (voltage slowly down when exceeding 1100 ℃, reach the thermostatic control effect). One side of the gas inlet 1 is communicated with a user circulating fan. The gas outlet 2 is in communication with a customer process equipment pipeline. Two long edges of a shell box body positioned in a channel of the heating furnace are provided with symmetrical lifting lugs 11, and a base is provided with a fixed lug seat 12; a process gas outlet temperature measuring point 10 is arranged at the reducing position 8 of the outlet of the furnace body; a plurality of overtemperature protection temperature measuring points 9 are respectively arranged in the high-temperature furnace. Temperature signals fed back by the temperature measuring points are all transmitted into a matched control system, and are fed back to a user DCS system for regulation and control through the silicon controlled rectifier conduction angle in cooperation with electric power regulation PID operation.
After adopting foretell structure, because the resistance area heater interface that sets up side by side on heating furnace passageway one side, resistance area heater radially inserts in the heating furnace and stretches into heating furnace opposite side (interior fixing bracket) through the interface, evenly arrange in every resistance area heater stove for the air heating is even in the stove, has both guaranteed the insulation between corundum pipe 7, resistance area 13 and casing and the radiation protection board 5, has improved the product thermal efficiency simultaneously, and has shortened the heat time greatly. In addition, the temperature measuring port is arranged between the high-temperature-resistant corundum pipes, chemical tail gas and waste gas flow through the blower, the heating uniformity and the temperature measuring accuracy are greatly improved, the structural design is reasonable, the manufacturing cost is reduced, benefits are increased for enterprises, and particularly, the temperature measuring device has good reference and popularization and use values for the environmental protection industry.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
