Problems solved by technology

[0002] In order to prevent the dust in the flue gas from depositing in the flue, the flue gas flow rate is generally required to be 10-15 m / s. Now in some special occasions, the flue gas flow rate must be reduced to about 7 m / s, so it is inevitable The ground will accumulate ash, and if the humidity of the flue gas is high and the temperature of the flue gas is lower than the acid dew point, the ash will scale on the flue wall and is difficult to remove

Embodiment Construction

[0013] Such as Figure 1~2 As shown, a soot pipe cleaning device includes a water pipe 2 arranged in the axial direction on the inner top of the soot pipe 1. The water pipe 2 is provided with nozzles 3 spraying toward the inner wall of the soot pipe at intervals. The nozzle is provided with a control valve 3. The nozzle The spraying angles are not the same. There are screw rods 5 arranged in the axial direction on both sides of the soot pipe 1, and a plurality of ash shovel plates 6 arranged at intervals are connected between the screw rods 5 on both sides. The ash shovel plates 6 are arc Shaped structure and its lower side is attached to the inner side wall of the lower part of the soot pipe 1; the two ends of the ash shoveling plate 6 are hinged on the nut seat 7 threaded with the screw rod 5 so that when the screw rod rotates, the ash shoveling board is driven to move in the axial direction. When cleaning is required, spray water with chemical reagents onto the inner wall o...

Abstract

The invention relates to an ash removing device for a soot pipeline and a work method of the ash removing device for the soot pipeline. The ash removing device for the soot pipeline comprises a water pipe located on the top of the inner side of the soot pipeline and arranged in the axial direction; injection nozzles performing injection towards the inner wall of the soot pipeline are arranged on the water pipe at intervals; the two sides of the inner portion of the soot pipeline are provided with lead screws arranged in the axial direction; a plurality of ash shoveling plates arranged at intervals are connected between the lead screws on the two sides; each ash shoveling plate is of an arc-shaped structure, and the lower side face of each ash shoveling plate is attached to the inner side wall of the lower portion of the sooth pipeline; and the two ends of each ash shoveling plate are hinged to a nut base in threaded connection with the lead screws so that the lead screws can drive the ash shoveling plates to move in the axial direction when the lead screw rotates. The ash removing device for the soot pipeline is simple in structure and easy, convenient and fast to operate, solves the problems that because the smoke gas flowing speed in the soot pipeline is low, soot remains, forms scales and cannot be removed easily, and is safe and stable, high in practicability, good in soot removing effect and high in efficiency.

Description

technical field [0001] The invention relates to a soot pipe cleaning device and a working method thereof. Background technique [0002] In order to prevent the dust in the flue gas from depositing in the flue, the flue gas flow rate is generally required to be 10-15 m / s. Now in some special occasions, the flue gas flow rate must be reduced to about 7 m / s. The ground will accumulate ash, and if the humidity of the flue gas is high and the temperature of the flue gas is lower than the acid dew point, the ash will be scaled on the flue wall and it is difficult to remove. Contents of the invention [0003] In view of this, the object of the present invention is to provide a soot pipe cleaning device and its working method which are easy to use, good in cleaning effect and high in efficiency. [0004] The present invention is realized by the following schemes: a soot pipe cleaning device, comprising a water pipe arranged axially at the top of the inner side of the soot pipe, a...
