Preferably, the purge gass, which pick out end 512, includes external threaded surface, easy to be connected with reversal valve.
Preferably, the material of the flow regulator pieces 52 can be straight carbon steel, stainless steel or copper.
Preferably, the internal connecting hole 5111 is threaded hole, easy to be connected with purge gass access tube.
The present invention further also provides a kind of commutation purge system, as shown in figure 5, including reversal valve 2 and above-mentioned purging
Piecing devices 5.Wherein, the reversal valve 2 includes combustion gas pipe nozzle 21, flue gas pipe nozzle 22, burner front tube pipeline joint 23, respectively
For being connected with combustion gas adapter 4, flue gas adapter 3, burner preceding pipeline 1；The purging piecing devices 5 include sequentially connected purging
Connector 51 and flow regulator pieces 52, the purging connector 51 is connected on the valve body of the reversal valve 2, and is connect with the burner preceding pipeline
Mouth 23 connects.
Since the commutation cycle of reversal valve is generally at 1-5 minutes or so, combustion gas reversal valve acts frequently, therefore purges pipeline
6 may also set up an automatic valve, such as solenoid valve 7.
The appropriate location for the valve body that can be communicated in combustion gas reversal valve 2 with burner preceding pipeline 1 sets a purge hole, and installation is blown
Sweep piecing devices 5.Threaded hole, installation purging connector 51, the interior installation flow regulator pieces of connector can be specifically opened on the valve body of reversal valve 2
52, then pipe fitting 8 (as shown in Figure 2) is screwed on, purge air through pipeline and be connected to manifold, purge installation purging valve on pipeline 6.
Certainly, purging point may also be arranged on burner preceding pipeline 1, and valve body can be not provided with purge hole, but remaining in valve body
It is clean that combustion gas will be unable to purging.The appropriate location of the valve body specifically communicated in combustion gas reversal valve 2 with burner preceding pipeline 1 sets one
Purge hole, installation purging connector 51, access purging pipeline 6.Purge gas can take compressed air or nitrogen.
To overhaul blow down valve, hand-operated valve can be set before and after blow down valve, when production is all turned on.
It is external screw thread to purge 51 one end of connector, is assembled with 2 valve body of reversal valve, the other end is internal thread, is filled with pipe fitting 8
Match somebody with somebody, purging 51 air intake of connector (at internal thread), installs flow regulator pieces 52.
Diameter, thickness and the perforate of flow regulator pieces 52 are required to calculate and determine.
The automatic valve can be with 2 electrical interlocks of reversal valve.
For convenience of maintenance purge system, hand-operated valve can be set before or after automatic valve, when production is all turned on.
Because reversal valve 2 connects the burner and regenerative apparatus of both direction, the burner front tube pipeline joint 23 includes first and burns
Mouth front tube pipeline joint and the second burner front tube pipeline joint (being not shown on figure), the purging piecing devices accordingly include the first purging
Piecing devices and the second purging piecing devices (being not shown on figure), the first purging piecing devices and the first burner front tube
Pipeline joint connects, the second purging piecing devices and the second burner preceding pipeline orifice.
The method that the present invention carries out commutation purging using above-mentioned commutation purge system, comprises the following steps：Changed when described
Before burner preceding pipeline 1 will be entered smoke evacuation state from input combustion gas to valve 2, the purging piecing devices are opened；To the purging
Piecing devices are passed through purge gass and the burner preceding pipeline 1 are purged；When it is described purging terminate, perform the reversal valve 2
Commutation action, the burner preceding pipeline 1 are changed into smoke evacuation state.
Specifically, when the reversal valve 2 is in the first commutation states, the first burner front tube pipeline joint and the combustion
Gas pipe nozzle 21 connects, and the second burner front tube pipeline joint is connected with the flue gas pipe nozzle 22, before first burner
The first purging piecing devices of pipe joint connection participate in purging, described in the second burner preceding pipeline orifice
Second purging piecing devices are closed.
When the reversal valve 2 is in the second commutation states, the second burner front tube pipeline joint is taken over the combustion gas
Mouth 21 connects, and the first burner front tube pipeline joint is connected with the flue gas pipe nozzle 22, connect with the second burner preceding pipeline
The second purging piecing devices of mouth connection participate in purging, are blown with described the first of the first burner preceding pipeline orifice
Piecing devices are swept to be closed.
The purge gass are compressed air or nitrogen.For security consideration, preferably purge gass are nitrogen.
During control, the purging piecing devices 5 can be subjected to electric automatic interlock control with the reversal valve 2.Work as commutation
Before valve 2 will enter smoke evacuation state, purging automatic valve is first turned on, purging compressed air or nitrogen are passed through, to burner preceding pipeline 1
Purged, purge time is calculated according to caliber and duct length and determined.Then reversal valve 2 acts, for state of discharging fume, delay
Afterwards, as after 0.5s or so, closed purging automatic valve, after commutating period arrives, reversal valve 2 acts, and to supply combustion gas state, purging is certainly
Movable valve remains off during this period, until next smoke evacuation state, repeats above-mentioned action.
The simple system of the present invention, passes through the systems such as purging connector, flow regulator pieces, pipeline, blow down valve that commutate, it is possible to will manage
Residual combustion gases are purged in burner hearth in road, greatly reduce the content of CO in flue gas.
The present invention coordinates the special designing of flow regulator pieces, and purging connector possesses throttling function, no matter stove how many
Root radiation pipe burner tip, it is no matter far and near apart from purge gass contact, it can achieve the purpose that balance, stablize supply and requirement.
The blow down valve of the present invention and reversing valve connecting lock control, are manually operated without people, improve automatization level.
High pressure, high flow rate purge gass can be used in the present invention, therefore purging pipe diameter is small, purging valve specification is small,
Pipe arrangement is simple, takes up space small.
The purging atmospheric pressure of the present invention is high, flow velocity is high, and the time of purging is short, and the time of combustion system cutoff is short, to burner hearth
The influence of pressure is small.
For purge gass of the present invention as used compressed air, it, which is passed through in burner hearth, may also participate in burning, will not cause to waste.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate example of the present invention, and simultaneously
The non-restriction to embodiment.For those of ordinary skill in the field, can also do on the basis of the above description
Go out other various forms of changes or variation.There is no necessity and possibility to exhaust all the enbodiments.And thus drawn
Among the obvious changes or variations that Shen goes out is still in protection scope of the present invention.
