To achieve the goals above, the utility model provides following technical scheme:
The utility model provides a kind of rinse-system of gasification installation gasification furnace liquidometer suction side, including for liquid level
The negative-pressure irrigation ring that suction side measurement pipe is rinsed is counted, is communicated with the inflatable body that can input purge gass on negative-pressure irrigation ring,
The flushing machine that can input flushing water is communicated on negative-pressure irrigation ring.
Further, it is provided with first through hole on negative-pressure irrigation ring, to be connected to inflatable body.
Further, inflatable body includes snorkel and blower, and blower is logical by snorkel and negative-pressure irrigation ring first
Hole connection.
Further, it is provided with the second through-hole on negative-pressure irrigation ring, to be connected to flushing machine.
Still further, flushing machine includes water pipe and water pump, water pump is connected by water pipe and the second through-hole of negative-pressure irrigation ring
It is logical.
As an option, be additionally provided with guide pipe on the inside of negative-pressure irrigation ring, guide pipe be set to the second through hole with water
Pipe is connected.
Compared with prior art, the utility model has the advantage that
The rinse-system of the gasification installation gasification furnace liquidometer suction side of the utility model, in gasification furnace liquidometer suction side
Installation blows afloat mechanism and flushing machine on pressure pipeline, so that the cinder being deposited in suction side is kept moisture state, using flushing
Water adds purge gass while the method rinsed is rinsed, and can effectively wash away cinder.

Specific embodiment
As shown in Figure 1, the installation principle of the gasification furnace liquidometer of gasification installation, including gasification furnace 100, suction side measuring machine
Structure 101, positive pressure side measuring mechanism 102 and pressure difference transmitter 103 measure the differential pressure of positive and negative pressure side by differential pressure transmitter 103,
Gasification burner liquid level 1001 can be gone out by Conversion Calculation.
As shown in Figure 2 and Figure 3, the rinse-system of gasification installation gasification furnace liquidometer suction side provided in this embodiment, as
The rinse-system of suction side measuring mechanism 101, including the negative-pressure irrigation ring for being rinsed to liquidometer suction side measurement pipe 1
2, the inflatable body that can input purge gass is communicated on negative-pressure irrigation ring 2, and flushing water can be inputted by being communicated on negative-pressure irrigation ring 2
Flushing machine.
Wherein, 2 one end of negative-pressure irrigation ring is connected to pressure with 100 inner cavity of gasification furnace by measurement pipe 1, is arranged in measurement pipe 1
There is valve；Suction side pressure is delivered to pressure difference transmitter by capillary 3 by 2 other end of negative-pressure irrigation ring.
It is provided with first through hole on negative-pressure irrigation ring 2, to be connected to inflatable body.Inflatable body includes snorkel 4 and blower,
Blower is connected to by snorkel 4 with 2 first through hole of negative-pressure irrigation ring.It is provided with air valve on snorkel 4, to control the big of tolerance
It is small.Air blower etc. can be used to blast purge gas in blower.
The second through-hole is provided on negative-pressure irrigation ring 2, to be connected to flushing machine.Flushing machine includes water pipe 5 and water pump, water
