Tail gas heated air circulating device of dry ammonium furnace

Abstract

The invention discloses a tail gas heated air circulating device of a dry ammonium furnace. The tail gas heated air circulating device of the dry ammonium furnace comprises a bottom plate and an installing plate, wherein one side of the upper end of the installing plate is fixedly provided with a heating box, a cavity is formed in the heating box, a separating plate is fixed between opposite sidewalls in the cavity, the cavity is separated into a dedusting area and a heating area by the separating plate from top to bottom, the side wall of one end of the heating box is provided with a first exhaust pipe and a second exhaust pipe in a penetrating way, one end of the second exhaust pipe is connected to one end of the first exhaust pipe, and one end of each of the first exhaust pipe and thesecond exhaust pipe passes through the side wall of one end of the heating box and is extended into the heating area and the dedusting area. Through improvement of a heated air circulating device, thetail gas heated air circulating device of the dry ammonium furnace is capable of solving the problem that heat in a discharged tail gas is wasted, realizing purposes of heating and dedusting the tailgas and recycling the heat, reducing energy loss, improving a utilization ratio, reducing the cost, and protecting the environment, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of hot air circulation, in particular to a hot air circulation device for tail gas of a dry ammonium furnace. Background technique [0002] At present, the drying of wet ammonium chloride in domestic and foreign alkali industries generally adopts fluidized bed fluidized bed furnace, which is dry ammonium furnace. Foul gas. The tail gas of the traditional dry ammonium furnace is directly emptied after being filtered by the cyclone separator and the bag filter. [0003] The tail gas of the dry ammonium furnace contains ammonia in the air, and the direct discharge does not meet the requirements of the environmental protection policy. The traditional way is basically to use the direct discharge method. The on-site environment is poor, the pressure of environmental protection is high, the gas after heating and heat tracing is discharged, which affects energy consumption, cannot be recycled for recycling, wastes...

AI Technical Summary

Problems solved by technology

The on-site environment is poor, the pressure of environmental protection is high, the gas after heating and heat tracing is discharged, which affects energy consumption, cannot be recycled for recycling, wastes energy resources, increases costs, and pollutes the environment. For this reason, we propose a Dry ammonium furnace tail gas hot air circulation device to solve the above problems
