Problems solved by technology

When the spiral slagging machine is used to discharge the boiler, the high temperature resistance requirements of the screw shaft and the shell of the screw slagging machine are high, the processing of the screw slagging machine is difficult and the processing cost is high
In addition, if the temperature of the hot slag discharged from the boiler is too high and the temperature of the shell, especially the screw shaft, is too high, it is easy to cause the jamming phenomenon of the screw slag discharge machine, which is not conducive to the discharge of waste slag.

Embodiment 1

[0059] Such as figure 1 As shown, the spiral slagging device 100 used in the boiler 1000 in this embodiment includes a slag cooler 1 for cooling waste slag, a spiral slagging machine 2 and cooling medium processing equipment 4 .

[0060] Specifically, the slag cooler 1 is provided with an inlet 11 and an outlet 12, and the inlet 11 is connected to the slag discharge port 200, so that the waste slag in the boiler 1000 can be discharged through the slag discharge port 200, and then discharged into the slag cooler 1 through the inlet 11. inside, so that the slag cooler 1 can preliminarily cool the waste slag entering the slag cooler 1 .

[0061] Specifically, such as figure 1 and Figure 5 As shown, the screw slag discharger 2 includes a casing 21, a screw shaft 22 and a cooling flow path for cooling the waste slag in the casing 21. The cooling flow path includes a first sub-flow located in the side wall of the casing 21 Road 233. The housing 21 is provided with a material inle...

Embodiment 2

[0066] Such as figure 2 As shown, the spiral slagging device 100 used in the boiler 1000 in this embodiment includes a slag cooler 1 and a spiral slagging machine 2 for cooling waste slag.

[0067] Specifically, the slag cooler 1 is provided with an inlet 11 and an outlet 12, and the inlet 11 is connected to the slag discharge port 200, so that the waste slag in the boiler 1000 can be discharged through the slag discharge port 200, and then discharged into the slag cooler 1 through the inlet 11. inside, so that the slag cooler 1 can preliminarily cool the waste slag entering the slag cooler 1 .

[0068] Specifically, such as figure 2 and Figure 5 As shown, the screw slag discharger 2 includes a casing 21, a screw shaft 22 and a cooling flow path for cooling the waste slag in the casing 21. The cooling flow path includes a first sub-flow located in the side wall of the casing 21 Road 233. The housing 21 is provided with a material inlet 211 and a material outlet 212, the...

Embodiment 3

[0073] Such as image 3 As shown, the spiral slag discharge device 100 used in the boiler 1000 in this embodiment includes a slag cooler 1 for cooling waste slag, a feeder 5 , a processing device 3 and a spiral slag discharger 2 .

[0074] Specifically, the slag cooler 1 is provided with an inlet 11 and an outlet 12, and the return device 5 is arranged between the slag outlet 200 of the boiler 1000 and the inlet 11 of the slag cooler 1 to stably send the waste slag discharged from the slag outlet 200 into the slag cooler 1. Thus, after the waste slag in the boiler 1000 is discharged into the feeder 5 through the slag discharge port 200, it can be discharged into the slag cooler 1 through the inlet 11, so that the slag cooler 1 can conduct preliminary processing on the waste slag entering the slag cooler 1. cool down.

[0075] Specifically, such as image 3 and Figure 5 As shown, the screw slag discharger 2 includes a casing 21, a screw shaft 22 and a cooling flow path for...

Abstract

The invention discloses a spiral deslagging device for a boiler, and a deslagging method. The spiral deslagging device comprises a slag cooler and a spiral deslagging machine, wherein the slag cooler is provided with an inlet and an outlet; the inlet is connected with a deslagging port; the spiral deslagging machine comprises a shell, a spiral shaft and a cooling flow path for cooling waste slag in the shell; the shell is provided with a feeding port and a discharging port; the feeding port is connected with the outlet; the cooling flow path is provided with a cooling water inlet and a cooling water outlet; and the spiral shaft is rotatably arranged in the shell to convey the waste slag towards the discharging port. The spiral deslagging method comprises the following steps: discharging the waste slag discharged from the boiler into the slag cooler firstly and cooling for the first time; and discharging the waste slag cooled for the first time into the spiral deslagging machine, wherein the spiral deslagging machine comprises the spiral shaft and the cooling flow path, and the waste slag is pushed by the spiral shaft to move towards the discharging port of the spiral deslagging machine and to be cooled by the cooling flow path. The spiral deslagging device provided by the invention can reduce the temperature of the waste slag entering the spiral deslagging machine.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a spiral slagging device and a slagging method for boilers. Background technique [0002] Generally, the temperature of the waste slag discharged from the boiler is relatively high. When the spiral slagging machine is used to discharge the slagging of the boiler, the high temperature resistance requirements of the screw shaft and the shell of the screw slagging machine are high, and the processing of the spiral slagging machine is relatively difficult and the processing cost is relatively high. In addition, if the temperature of the hot slag discharged from the boiler is too high and the temperature of the shell, especially the screw shaft, is too high, it is easy to cause the jamming phenomenon of the screw slag discharge machine, which is not conducive to the discharge of waste slag. Contents of the invention [0003] This application is based on the inventor's discovery and...
