Abstract

The invention discloses an H-shaped warping sheet economizer. The H-shaped warping sheet economizer comprises a smoke inlet formed in one end of a shell and a smoke outlet opposite to the smoke inlet,and the smoke inlet and the smoke outlet communicate with a heat exchange smoke cavity in the shell. The top of the smoke outlet is provided with a water inlet header, and the position, close to thesmoke inlet, of the top of the shell is provided with a water outlet header. Each of the water inlet header and the water outlet header is provided with a temperature sensor and a pressure sensor. A water inlet pipe of the water inlet header is provided with an electric valve. A control panel is arranged on the side face of the shell and provided with a display screen. An AT89S51 chip is embeddedin the control panel. A DI6 pin and a DI7 pin on the AT89S51 chip are electrically connected with the temperature sensors, a DI4 pin and a DI3 pin are electrically connected with the pressure sensors,and a DI2 pin is electrically connected with a buzzer. The electric valve is connected with a pin DO1 and a 24 v power source end, and the display screen is connected with a pin DO2 and the 24 v power source end.

Description

technical field [0001] The invention belongs to the technical field of economizers, and in particular relates to an H-shaped sliced ​​economizer. Background technique [0002] During the smelting and production process of ferrosilicon furnace, a large amount of high-temperature flue gas entrained with fine dust particles is produced. To produce 1 ton of 75% ferrosilicon, theoretically about 1500-2000Nm 3 Furnace gas, the main component of flue gas is N 2 , O 2 , CO 2 、H 2 O, due to the large air excess coefficient, it is basically close to the air composition. [0003] SO in flue gas 2 The content depends on the amount of sulfur brought into the raw material, mainly determined by the sulfur content of the reducing agent. The amount of sulfur brought in by 1 ton of 75% ferrosilicon raw material is generally about 5-10kg, of which 90% is burned into SO 2 After entering the flue gas, the sulfur content of the flue gas in the semi-closed electric furnace is generally 0.1...
