In addition, the main combustion furnace 110 has a fire door 114 installed on the front wall of the main combustion furnace 110, the main combustion burner 115 installed on the rear wall of the main combustion furnace 100, and the main combustion burner 115 It may include a main air blower 116 installed on the rear wall upward, and the rail 118 for the refractory truck 120 is installed on the bottom 117 of the main combustion furnace (110).

At this time, the main blower 116 may be formed to be inclined to face the flame generated from the main combustion burner 115, accordingly, the required amount of air smoothly through the main blower 116 mounted to the main blower 116. Can be transferred to the flame, and by performing the secondary combustion smoothly, complete combustion can be induced.

In addition, the main combustion burner 115 is capable of adjusting the angle, such as up and down angle 25 °, left and right angle 15 °, forward and backward movement 500mm, etc., it can have the effect of eliminating the flame retardant portion and shortening the makeup time.

In addition, since the main combustion burner 115 is coupled to a loop circuit of a controller (not shown) in which the temperature, pressure, and amount of combustion in the furnace (main combustion chamber or reburn chamber) are automatically controlled, combustion can be realized completely. As the gas may stay in the interior of the main combustion furnace for more than 2 seconds, it is possible to induce complete combustion.

The rail 118 for the refractory truck 120 may be installed based on the upper surface of the bottom 117 of the main combustion furnace 100. In addition, the bottom of the bottom 117 of the main combustion furnace 110 may be further provided with a blower 130 for supplying cooling air through the bottom 117 toward the refractory truck 120 on the rail 118. have.

Blower 130 includes a blower located on the lower side of the toilet, the main blower pipe connected to the discharge port of the blower, and a plurality of branch pipes branched from the main blower, where the end of each branch pipe is the main combustion furnace 110 It may extend upward through the bottom 117 of).

And the combustion gas cooling device 170 is coupled to penetrate through the connection pipe 119 of the crematory 100, and serves to sequentially cool the combustion gas by the gas cooler (170a) and the gas heat exchanger (170b). I can be in charge.

The flue gas cooler 170 may be coupled to the flue gas treatment device through an exhaust line 172.

On the other hand, one side of the crematorium 100 may include a cooling chamber 140 in which the refractory truck 120 is located at the start or end of the makeup.

The cooling chamber 140 may be provided with an automatic front door and an opening / closing device installed around the entrance to the main combustion chamber 100 and the ceiling of the cooling chamber 140 and the connecting pipe of the crematory 100. Between the 119, the vent pipe 142 having the upper chamber upper damper may be installed to be connected to the exhaust pipe 150 according to the features of the present invention.

Here, the exhaust pipe 150 may be an air conditioner installed in the cooling chamber 140 to shorten the makeup time by enabling rapid cooling after makeup.

Therefore, the exhaust pipe 150 is for discharging dust and hot air generated from the cooling chamber 140 to the outside, as shown in FIG. 3 or FIG. 4. The suction part 152 which extends to the position close to the fire-resistant trolley | bogie 120 which moves is located, the communication part 154 which runs vertically from the suction part 152, and the horizontal direction to the end side of the said communication part 154. The expansion unit may be configured as a discharge unit 156 communicating with the outside.

The exhaust pipe 150 is preferably made of a stainless material, KSD-3698L cold-rolled stainless steel sheet (STS-304) can be manufactured to a thickness of 0.6mm or more.

Furthermore, the suction part 152, the communication part 154, and the discharge part 156 may be fixed by bolt fastening or screw fixing, pressure welding, and spot welding after forming a steel plate, and the joints between the parts may be granular joints or overlaps. It may be a joint and a pressing joint.

In addition, the sealing joint can be added to the non-acetic acid system.

The suction part 152 manufactured as described above may have a polygonal shape, and the suction hole 152a opened to face the fire truck may be formed at an oblique inclination angle.

The angle of inclination may be about 35 ° to 45 ° based on the refractory truck 120 direction.

In addition, a sirocco blower 160 may be further installed at the communicating portion 154 that runs vertically from the suction portion 152.

The sirocco blower 160 is narrow and forward size, the blade wing is suitable for the air conditioning device of about 20 to 60, preferably, the motor and the fan can be separated in the state installed on the communication unit 154 side Inspection and maintenance can be easy.

The discharge part 156 is a part connected to the vent pipe 142 described above. The discharge part 156 is extended from the vertically communicating part 154 in the front horizontal direction, and the extension length may be about 2 m or less.

And the end surface of the discharge portion 156 is formed as an inclined surface can prevent dust from falling and accumulate.

The effect of this invention is demonstrated by such a structure.

Hot air including fine dust generated when applying makeup in the first and second reburning chambers 111 and 112 of the main combustion furnace 110 by applying a degree of about 1000 degrees Celsius is made by the operation of the blower 130. Through the connection pipe 119 connected to the furnace 100, the gas cooler 170a and the gas heat exchanger 170b are introduced into and cooled.

Here, the gas cooler 170a may play a role of making the combustion gas quenched at a temperature of 700 to 850 ° C. by mutually exchanging the combustion gas supplied from the connection pipe 119.

The cooled air is then purged and discharged into the atmosphere while passing through a dust collector (not shown).

On the other hand, when the make-up operation is completed in the crematorium 100, the ashes are moved to the pre-cooling chamber 140 by the refractory truck 120 and cooled to a predetermined temperature.

At this time, the hot air containing fine dust from the ashes which have just finished makeup flows to the gas cooler 170a and the gas heat exchanger 170b along the exhaust pipe 150 and the vent pipe 142 of the cooling chamber 140 to cool. do.

Here, when the temperature of the contaminated air generated in the cooling chamber 140 is about 180 to 200 degrees Celsius, the temperature sensor installed at a predetermined position of the gas cooler 170a connected to the vent pipe 142 of the crematorium 100 ( The sirocco blower 160 installed in the exhaust pipe 150 is operated by the signal of the not shown) to cool the hot air discharged from the cooling chamber 140.

At this time, the air including the contaminated dust emitted from the inlet 152a of the close distance from the inlet 152 of the exhaust pipe 150 toward the refractory truck 120 through the sirocco blower 160 of the communication unit 154. Effective suction is made, and the sucked dust and air can be smoothly induced to the exhaust pipe 142 without the bottleneck through the discharge portion 156 extended through the communication portion 154.

According to the embodiment of the present invention as described above, the cooling and dust intake efficiency can be maximized through the exhaust pipe and the blowing fan installed to extend close.

In addition, there is no need to install a separate dust purification device in the entire cooling chamber due to the increase in dust collection efficiency. In addition, the amount of dust adhering to the worker during the osteopathy is significantly reduced to improve the working environment.
