Described first round tube wall arranges peep hole window.
Lower end between each annulus, arranges the draining valve (DN25) that connects main sewer, amounts to 6.
The material of described annulus is carbon steel.
A using method of being convenient to the gas filter for pipeline cleaning, comprises the following steps,
(1) open the valve of admission line and outlet pipe, leave the desulfurization biogas of desulfurizing tower successively by the passage of each grate plate;
(2) the liquid foam in biogas is stopped by passage, is trapped in each grate plate, contains the salt and the sulphur mud component that in sweetening process, produce and be deposited in grate plate in liquid foam;
(3) when deposition solid component reaches certain thickness in grate plate, close the valve of admission line and outlet pipe, open first round tube wall, unload each grate plate and clean, after cleaning, press original structure assembling;
(4) repeating step (1)-(3), filter biogas.
Aborning, piping filter is installed in parallel two, one open one standby.If grate plate in use stops up seriously, just can, in the situation that not affecting production, can realize at any time the cleaning of filter.
In piping filter design of the present utility model, consider the possibility that prevents that long-time use from resulting in blockage, so in use, cleaning at any time.As utilize the overall general overhaul time, just can complete the cleaning of grate plate.When cleaning, open first round tube wall, second round tube wall, pull down respectively grate plate, can realize labor cleaning, cleaning is thorough, and convenient clean.
