Abstract
The explosive anti negative sweeping has filters on the process tunnel, heater outside the filter, electromagnetic valve SV1 and SV3 between the heater and analysis instrument, SV2 an SV4 connected between the SV1 and SV3, the other end of the SV2 connected to the filter, the other end of the SV4 connected with the nitrogen storage can, and a electric control pneumatic ball valve SV5 being set between the process tunnel and the filter. It has good sweeping effect. It improves the operation rate of the equipment, reduces the failure rate, ensures the stable running, improves economic benefits, and alleviates labor of the maintaining staff.
Description
Technical field
The present invention relates to industrial online gas element analyzer table applied technical field, can be widely used in the stable operation of the analysis meter under various complicated technology conditions.
Background technology
At present domestic industry is with the sample gas pretreatment unit of online gas element analyzer table, the sampling mode that adopts sample gas to filter more, and the cleaning of filtrator adopts blow-back to sweep mode, and the blowback mode of sweeping has two kinds: 1, continuous purging to filtrator; 2, add the purging of pulsating continuously to filtrator.
The shortcoming that above-mentioned two kinds of blowback modes of sweeping exist is: the energy when purge gas arrives the filtration outer core has dropped to very low, the foul that is suspended to outer wall can not be blown off, and the time one is long, will cause plugged filter, has influenced the stable operation of analysis meter.
Summary of the invention
The purpose of this invention is to provide a kind of explosive type back-blowing method, this method can be removed the foul on the filtrator effectively, improves the running rate of equipment, reduces equipment failure rate, guarantees equipment stable operation, increases economic efficiency, and reduces maintainer's labour intensity.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of explosive type back-blowing method, it is characterized in that: this method is to set up control device between process pipe (1) and filtrator (2), this control device forms passage for making process pipe, filtrator and energy storage canister, and can make gas energy storage in the filtrator, and can abrupt release and the device that can carry out repeatedly, purge gas forms high pressure conditions in filtrator after, with the energy abrupt release, this process is carried out repeatedly, makes attached to the foul on the filtrator outer wall to be fallen by powerful airflow scouring.
Described control device is the ecp ball valve.
The beneficial effect that the present invention compared with prior art has is:
Before the improvement, to crossing the purging of filter core, the energy when arriving the filtration outer core owing to purge gas has dropped to very low, the foul that is suspended to outer wall can not be blown off, and the time one is long, will cause plugged filter.After the improvement, will overcome the drawback before improving, when SV5 closed, in filtrator, SV5 opened with the purge gas storage, with the energy abrupt release, made attached to the foul on the filtrator outer wall to be fallen by powerful airflow scouring, had therefore reached the purging effect.This mode improves the running rate of equipment, reduces equipment failure rate, guarantees equipment stable operation, increases economic efficiency, and reduces maintainer's labour intensity.
Description of drawings
Fig. 1 is a kind of schematic diagram of explosive type back-blowing method.
Embodiment
See Fig. 1, a kind of explosive type back-blowing method, process pipe 1 connects filtrator 2, and filtrator 2 outsides are provided with well heater 3, establish solenoid valve SV1, SV3 between filtrator 2 and the analytical instrument 5; Be connected to solenoid valve SV2, SV4 between solenoid valve SV1, SV3, the other end of solenoid valve SV2 links to each other with filtrator, and the other end of solenoid valve SV4 links to each other with nitrogen energy storage canister 4, sets up ecp ball valve SV5 between process pipe and filtrator.
Its course of work is described below:
Normal operating condition: solenoid valve SV2, SV4 close, and SV1, SV3, SV5 open, and sample gas enters in the analytical instrument through filter.
State is swept in blowback: (blowback is swept control and controlled by Programmable Logic Controller)
1), blasting type purged filter core: solenoid valve SV2, SV3 close, and SV1, SV4 open, and SV5 opened, closes once in every interval in 5 seconds, and after continuous 5 times (can adjust), SV5 often opens.
2), continous way purges filtrator: solenoid valve SV3 closes, and SV1, SV2, SV4, SV5 open.
Claims (3)
1, a kind of explosive type back-blowing method, it is characterized in that: this method is to set up control device between process pipe (1) and filtrator (2), this control device forms passage for making process pipe, filtrator and energy storage canister, and can make gas energy storage in the filtrator, and can abrupt release and the device that can carry out repeatedly, purge gas forms high pressure conditions in filtrator after, with the energy abrupt release, this process is carried out repeatedly, makes attached to the foul on the filtrator outer wall to be fallen by powerful airflow scouring.
2, a kind of explosive type back-blowing method according to claim 1 is characterized in that: described control device is the ecp ball valve.
3, a kind of explosive type back-blowing method according to claim 1, it is characterized in that: blowback is swept control and is controlled by Programmable Logic Controller;
