The technical problem to be solved by the utility model is realized by adopting the following technical scheme:

a gas purifier filtering device comprises at least two pipelines communicated with a purifier, wherein a plurality of pipelines are arranged in parallel, and each pipeline comprises a filter, a first valve arranged at the inlet end of the filter and a second valve arranged at the outlet end of the filter;

and adjusting pipes are communicated between every two adjacent pipelines, one ends of the adjusting pipes are communicated between the filter and the second valve, the other ends of the adjusting pipes are communicated between the filter and the first valve, and a third valve is further arranged on each adjusting pipe.

As a preferred example, the filter is connected to a cleaning pipe for blowing back gas to the filter for cleaning.

The filter device comprises a shell, a plurality of filters are arranged in the shell at intervals, the pipelines of the pipelines are all connected with the shell, and the inlet and the outlet of each pipeline are located between every two adjacent filters.

As a preferred example, a plurality of the cleaning pipes are each connected to the housing, and the inlet of each cleaning pipe is located between two adjacent filters.

As a preferred example, the filter is a high efficiency filter or an ultra high efficiency filter.

In a preferred embodiment, a plurality of the pipelines are connected in parallel and then provided with a fourth valve.

The utility model has the beneficial effects that: according to the utility model, through the arrangement of the plurality of filtering pipelines, particles of the molecular sieve are prevented from entering the heat exchanger, the equipment loss of the heat exchanger is reduced, the heat exchange effect is improved, and the efficiency of the purifying equipment is increased.

Detailed Description

In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.

As shown in fig. 1-3, a gas purifier filtering device comprises at least two pipelines communicated with a purifier 1, wherein a plurality of pipelines are arranged in parallel, and each pipeline comprises a filter 4, a first valve 2 arranged at the inlet end of the filter 4 and a second valve 5 arranged at the outlet end of the filter 4;

and an adjusting pipe 8 is communicated between two adjacent pipelines, one end of the adjusting pipe 8 is communicated between the filter 4 and the second valve 5, the other end of the adjusting pipe 8 is communicated between the filter 4 and the first valve 2, and a third valve 9 is further arranged on the adjusting pipe 8.

The filter 4 is communicated with a cleaning pipe 3, and the cleaning pipe 3 is used for blowing back gas to the filter 4 for cleaning.

Including a casing 10, a plurality of filters 4 interval sets up in casing 10, and the pipeline of a plurality of pipelines all is connected with casing 10, and the entry and exit department of pipeline all is located between two adjacent filters 4.

A plurality of cleaning pipes 3 are connected to the housing 10, and the inlet of each cleaning pipe is located between two adjacent filters 4.

The filter 4 is a high-efficiency filter or an ultra-high-efficiency filter, and is mainly used for trapping particulate matters with the particle size of more than 0.3 mu m and meeting the filtering precision of the molecular sieve particulate matters.

A plurality of pipelines are provided with fourth valve 6 after connecting in parallel, and when filter 4 carried out the blowback, fourth valve 6 can be opened, and gaseous partly got into heat exchanger 7 this moment, and partly is used for the blowback, also can close for whole gas carries out the blowback, strengthens the blowback effect.

The working principle is as follows: when in use, the gas in the purifier enters the pipeline, at the moment, all the first valves 2 and the second valves 5 are opened, the plurality of pipelines are in a parallel state, the gas finally enters the heat exchanger 7 through the plurality of filters 4, the gas inlet speed is improved, under the other working condition, the first valves 2 of the first group of pipelines are opened, the second valves 5 of the first group of pipelines are closed, the third valves 9 on the adjusting pipes 8 are opened, the first valves 2 and the second valves 5 of the subsequent pipelines are closed, and the second valves 5 of the last group of pipelines are opened, so that the plurality of filters 4 are connected in series for use, the service cycle of the filters 4 is improved, when in back blowing, only the first valves 2 of one group of pipelines are opened, the rest first valves 2 are closed, the second valves 5 and the valves on the cleaning pipes 3 are opened, at the moment, the gas in the system can be used for back blowing and cleaning other filters 4, the method is the same, the different first valves 2 are controlled to be opened and closed.
