Detailed Description

The core of the utility model is to provide a pipeline system to effectively clear up the interior flying dust deposit of pipeline.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a pipeline system, which includes a gas pipeline 1, a high-pressure gas pipe 4 and a high-pressure gas source 6; the gas pipeline 1 is a working pipeline to be cleaned, the high-pressure gas pipe 4 is connected with the gas pipeline 1, and a gas outlet 41 of the high-pressure gas pipe 4 is positioned in the gas pipeline 1; the high-pressure gas source 6 is communicated with the high-pressure gas pipe 4 and is used for introducing high-pressure gas into the gas pipeline 1 and purging the fly ash deposited on the inner wall of the gas pipeline 1 through the high-pressure gas.

The cleaning process of the pipeline system comprises the following steps: when the device works, high-pressure gas is introduced into the high-pressure gas pipe 4 by the high-pressure gas source 6, the high-pressure gas enters the gas pipeline 1 at a high speed through the gas outlet 41, the high-pressure gas blows the fly ash deposited on the inner wall of the gas pipeline 1, the fly ash is separated from the inner wall of the gas pipeline 1, and the blown fly ash is discharged along with the airflow in the gas pipeline 1, so that the cleaning of the fly ash deposited on the inner wall of the gas pipeline 1 is completed.

Further, in the present embodiment, the number of the high-pressure gas pipes 4 is plural, and the high-pressure gas pipes are arranged in order along the gas flow direction of the gas pipe 1. The gas outlet 41 of each high pressure gas pipe 4 can blow only the fly ash deposited on the inner wall around it, and therefore, the fly ash cleaning of the entire segment of the gas pipe 1 can be realized by arranging a plurality of high pressure gas pipes 4 in the gas flow direction of the gas pipe 1. The plurality of high-pressure gas pipes 4 may be respectively communicated with the high-pressure gas source 6, or may be communicated with the high-pressure gas source 6 through a main line.

Furthermore, each high-pressure gas pipe 4 is provided with a switch valve 5, and the switch valve 5 on each high-pressure gas pipe 4 is controlled to realize independent on-off of each high-pressure gas pipe 4, so that independent control is facilitated. Of course, a plurality of high-pressure gas pipes 4 may be opened and closed in a unified manner by a common on-off valve 5.

In this embodiment, the duct system further includes a gas nozzle 3 disposed at the gas outlet 41 of the high-pressure gas pipe 4, and the speed and range of the high-pressure gas injection are increased by the gas nozzle 3, which is beneficial to thoroughly cleaning the fly ash on the inner wall of the gas duct 1.

Further, the injection direction of the gas shower 3 is perpendicular or inclined to the inner wall of the gas pipe 1. With such an arrangement, the impact force of the fly ash acting on the inner wall of the gas pipeline 1 can be increased, thereby facilitating the fly ash to be blown off and separated from the inner wall. Of course, the closer to the vertical purge the better.

Furthermore, in this embodiment, the injection surface of the gas nozzle 3 is a cambered surface, so that the injection area of the high-pressure gas is larger, the cleaning is more effective, and the number of the high-pressure gas pipes 4 and the gas nozzle 3 can be reduced.

In this embodiment, the pipeline system is further optimized, and the pipeline system further comprises a fly ash sensing device 2 and a controller; the fly ash sensing device 2 is arranged in the gas pipeline 1 and around the gas outlet 41 of the high-pressure gas pipe 4, and is used for detecting fly ash information on the inner wall of the gas pipeline 1 around the gas outlet 41; the controller is connected with the switch valve 5 and the fly ash sensing device 2 and is used for controlling the corresponding switch valve 5 to be opened and closed according to the fly ash information detected by the fly ash sensing device 2.

When the flying ash sensing device works specifically, the flying ash sensing device 2 detects flying ash information on a pipe wall nearby the flying ash sensing device and sends the flying ash information to the controller, the controller judges whether the flying ash information exceeds a set value, if the flying ash information exceeds the set value, the switch valve 5 is controlled to be opened, and otherwise, the switch valve 5 is controlled to be closed. The fly ash information may specifically be the thickness of the fly ash. The fly ash sensing device 2 is preferably a thickness sensor. The automatic cleaning of the fly ash in the gas pipeline 1 is realized by the fly ash sensing device 2 and the controller.

Of course, the pipe system may not be provided with the fly ash sensing device 2 and the controller, but the switch valve 5 may be opened manually and periodically to clean the fly ash in the gas pipe 1 periodically.

Further, the controller controls the on-off valves 5 on the high-pressure gas pipes 4 to be sequentially opened along the gas flowing direction of the gas pipeline 1, namely, the on-off valves 5 on the high-pressure gas pipes 4 close to the gas inlet end of the gas pipeline 1 are opened first, and then, the other on-off valves 5 are sequentially opened along the gas flowing direction, so that the fly ash is discharged along the gas pipeline 1 along with the gas flow, and the interference of the high-pressure gas on the gas flow in the gas pipeline 1 is reduced. Of course, the switch valves 5 can be opened simultaneously, and the high-pressure gas ejected simultaneously disturbs the airflow in the gas pipeline 1 greatly, which is not beneficial to discharging the fly ash.

Further, the controller controls the opening interval time of the switching valves 5 on the adjacent two high pressure gas pipes 4 to be greater than or equal to 1 s. So set up, can reduce the interference of high-pressure gas to the air current in the gas pipeline 1, can improve cleaning efficiency again simultaneously.

In this embodiment, the pipeline system further comprises a water delivery pipe and a high-pressure water source; wherein, the water outlet of the water pipe is positioned in the gas pipeline 1, and the water pipe is arranged close to the high-pressure gas pipe 4; the high-pressure water source is communicated with the water delivery pipe and is used for spraying cooling water into the gas pipeline 1. So set up, when gas temperature was too high in gas pipeline 1, sprayed water in to gas pipeline 1 through the raceway to play the effect of gaseous cooling.

Further, in this embodiment, pipe-line system still includes the water smoke shower nozzle that sets up on the delivery port of raceway, and the cooling water in the high pressure water pipe passes through the water smoke shower nozzle and spouts with the form of water smoke, and the cooling area is big, and the cooling effect is better.

In this embodiment, the high-pressure air source 6 is a high-pressure air pump, and includes a high-pressure cylinder and a compressor.
