Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment of the utility model provides a generating set's boiler air feeder, as shown in fig. 1, this boiler air feeder includes air pipeline 1, pure oxygen pipeline 2 and gas pipeline 3, pure oxygen pipeline 2 parallel connection be in on the air pipeline 1, air pipeline 1 parallel connection be in on the gas pipeline 3, gas pipeline 3 still is connected with boiler furnace chamber 4, wherein, set up forced draught blower 7 on air pipeline 1's the entry, set up oxygen control valve group 8 on the pure oxygen pipeline 2, when using like this, air pipeline 1 is used for conveying the air, pure oxygen pipeline 2 is used for carrying the pure oxygen, gas pipeline 3 is used for carrying coal gas, parallelly connected the setting air pipeline 1 pure oxygen pipeline 2 with gas pipeline 3 carries the mist to boiler furnace chamber 4 in to burn in the boiler, and forced draught blower 7 with oxygen control valve group 8 can adjust the air and the oxygen that carry out the transport And further makes the whole combustion more sufficient. Meanwhile, the air pipeline 1, the pure oxygen pipeline 2 and the gas pipeline 3 are respectively connected with the boiler furnace chamber 4 through compensating pipelines, so that when the device is used, a gas component detection device is arranged in a chimney of the boiler, the combustion condition is determined by detecting the content of carbon monoxide, and then the gas in the boiler can be directly supplemented, so that the combustion efficiency is improved.
As shown in fig. 2, a pipe mixer 5 is disposed in the air pipe 1, the pipe mixer 5 achieves the purpose of uniform mixing through the action of a spiral set in the shape of a spiral blade when fluid flows through the pipe, when in use, the front end of the spiral set (i.e. the inlet of the pipe mixer 5) and the air pipe 1 form a first inlet and a second inlet, different gases enter the first inlet and the second inlet in a one-to-one correspondence manner to be mixed in the spiral set, and the gases are sufficiently and completely mixed after being led out from the pipe mixer 5.
Further, since the pure oxygen pipeline 2 is connected in parallel to the air pipeline 1, when the pipeline pressure in the pure oxygen pipeline 2 or the air pipeline 1 changes, the gas entering the pipeline mixer 5 may be a single component gas, for example, when the pipeline pressure in the air pipeline 1 is small, oxygen may affect the air transportation, the content of the necessary oxygen introduced into the pipeline mixer 5 is large, which may generate a deviation with a predetermined required oxygen concentration, therefore, in order to reduce the deviation, the gas guide plate is arranged in the air pipeline 1, the gas guide plate is arranged opposite to the pure oxygen inlet 21 on the air pipeline 1, and the air pipeline 1 is divided into a pure oxygen guide cavity 11 and an air guide cavity 12, wherein the outlet of the pure oxygen guide cavity 11 is communicated with the first inlet of the pipeline mixer 5, air water conservancy diversion chamber 12 with the second import of line mixer 5 aligns the intercommunication, makes oxygen and air more evenly enter into like this in the line mixer 5, further, gaseous guide plate with the last spiral external member integrated into one piece of line mixer 5 sets up, so not only make oxygen and air more evenly enter into in the line mixer 5, simultaneously in the installation, also be the installation that the staff is more convenient line mixer 5.
