Abstract
The rotary kiln waste heat recovery mechanism is characterized in that a kiln body is arranged on a frame body, a conical blanking hopper is arranged at the bottom of the kiln body, a ventilation hood is arranged on the frame body and positioned outside the conical blanking hopper, an air inlet pipe is arranged on one side of the ventilation hood, and an air outlet pipe is arranged on one side of the ventilation hood, which is opposite to the air inlet pipe. According to the rotary kiln waste heat recovery mechanism, the ventilation hood is arranged at the discharging conical hopper of the rotary kiln, and the air supply system of the decarburization furnace transfers heat through the ventilation hood and then sends air into the decarburization furnace, so that the decarburization efficiency is effectively improved, the temperature in the decarburization furnace is improved, the energy consumption of the decarburization furnace is reduced, a large amount of heat energy at the discharging position of the rotary kiln is recovered, the energy consumption is reduced, and the efficiency is improved.
Description
Technical Field
The utility model relates to the technical field of hazardous waste disposal and resource recycling.
Background
The rotary kiln blanking department produces a large amount of heat energy, and these heats do not retrieve and cause certain loss, and the low efficiency that also can reduce the decarbonization of blast temperature of decarbonization stove simultaneously, and the energy consumption is big, and how to retrieve the heat energy of rotary kiln to the decarbonization stove and utilize for the technical problem that this application solved.
SUMMERY OF THE UTILITY MODEL
The utility model provides a waste heat recovery mechanism of a rotary kiln, which aims to realize the purpose of recovering the heat energy of the rotary kiln to a decarburization furnace for utilization.
The technical scheme adopted by the utility model for realizing the purpose is as follows: rotary kiln waste heat recovery mechanism, furnace body 2 install on support body 3, and 2 bottoms of furnace body are hopper 4 under the toper, and 4 outside installation draft hoods 5 of hopper under the toper are located on the support body 3, and 5 one side of draft hoods are equipped with air-supply line 6, and the relative one side that lies in air-supply line 6 on the draft hoods 5 is equipped with out tuber pipe 7, and draft hoods 5 are square structure.
According to the rotary kiln waste heat recovery mechanism, the ventilation hood is arranged at the discharging conical hopper of the rotary kiln, and the air supply system of the decarburization furnace transfers heat through the ventilation hood and then sends air into the decarburization furnace, so that the decarburization efficiency is effectively improved, the temperature in the decarburization furnace is improved, the energy consumption of the decarburization furnace is reduced, a large amount of heat energy at the discharging position of the rotary kiln is recovered, the energy consumption is reduced, and the efficiency is improved.
Drawings
FIG. 1 is a front view of a rotary kiln of the present invention.
Fig. 2 is a structural view of a ventilation hood of a rotary kiln according to the present invention.
In the figure: 1. the furnace comprises a feeding hole, 2, a furnace body, 3, a frame body, 4, a conical discharging hopper, 5, a ventilation hood, 6, an air inlet pipe, 7 and an air outlet pipe.
Detailed Description
As shown in figure 1 of the rotary kiln, a furnace body 2 is arranged on a frame body 3, a feeding hole 1 is arranged at the upper part of the furnace body 2, and a conical discharging hopper 4 is arranged at the bottom of the furnace body 2. 4 outside installation draft hoods 5 of hopper under the toper on support body 3, draft hood 5 one side is equipped with air-supply line 6, it is equipped with air-out pipe 7 to lie in the relative one side of air-supply line 6 on draft hood 5, air-supply system of decarbonization stove is connected to air-supply line 6 and air-out pipe 7, retrieve a large amount of heat energy of rotary kiln unloading department, the air-supply system of decarbonization stove carries out the heat transfer through draft hood 5 and then sends into the decarbonization stove with wind in, the efficiency of decarbonization has been improved effectively, the temperature in the decarbonization stove has been improved, it also retrieves a large amount of heat energy of rotary kiln unloading department to have reduced the decarbonization stove energy consumption.
