Description

A kind of sand-proof energy-saving fresh air filtration system being easy to safeguard

Technical field

The utility model relates to air purification field, more particularly to a kind of VMC.

Background technology

The requirement to surrounding air for the data center module equipment is constant temperature and humidity, cleanliness factor height.Due to data equipment make used The continuous heat release of Cheng Zhonghui, in order to realize the guarantee of communications equipment room surrounding air, is traditionally all intended to use machine room Special precision empty Transferring in row refrigeration cool-down, not only investment is big, and the electric energy consuming every year is also considerable.According to the preliminary statistics, general communication equipment In room, the electric energy of more than 40% is consumed by air-conditioning equipment.Natural fresh air is utilized to freeze communications equipment room, beyond doubt one Power save mode preferable, convenient, efficient.In recent years, the existing case of the data center module having dust-filtering function VMC is used Occur.But for the environment based on bulky grain dust, such as common have desert, a bare soil class dust, in theory, because of Big for particle, it is easy to fall via first effect, middle high-efficient filter net filtration, as long as often changing filter screen, but being stranded when actually used Difficult heavy.The first effect of tradition VMC and in efficient filter screen place side by side, gap between the two is less, it is easy to by first effect filter Fine dusts filling after net filtration, being continuously increased of dust causes the pressure drop of VMC to raise, thus needs frequently to filter Net carries out changing and being cleaned system.This not only can bring huge workload, also can affect the properly functioning of machine room.

ZL201520407581.0 discloses a kind of sand-proof energy-saving fresh air system, and it comprises an ash fall room, dust One dismounting cleaning pond is set under the porous sieve plate of expansion chamber, new wind dust therein when by expansion chamber can rely on inertia and Enter cleaning pond by sieve plate, thus reduce filter replacement frequency.But the dust containing capacity cleaning pond at higher wind speeds is limited, and Secondary pollution can be produced when VMC is opened；And clean cleaning pond continually and need human cost, the dimension of VMC Protect certain difficulty.

In VMC, just the service life of effect filter screen is typically comparatively short, and the old filter screen changing is difficult to again repeat Utilize, directly abandon as discarded object, cause running cost to be difficult to reduce.

In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.

Content of the invention

In order to be able to solve the problems referred to above of the prior art, the utility model provides a kind of sand-proof joint be easy to and safeguard Can VMC.The VMC providing according to the utility model, can significantly reduce filter replacement frequency, reduction system clean Time.

The utility model provide VMC contain initial effect filtering section and middle high efficiency filter section, initial effect filtering section and in There is an ash fall room between high efficiency filter section, described expansion chamber have a filtering baffle vertical with Leads to new breeze direction, Expansion chamber top board is fixed in described filtering baffle upper end, and lower end does not contacts with expansion chamber floor, in roughing efficiency air filter and filtration Expansion chamber floor between baffle plate is the porous sieve plate of a horizontal positioned；Sedimentation between filtering baffle and middle high efficiency particulate air filter Floor, room is a tilted-putted porous sieve plate；It is a detachable for cleaning pond below porous sieve plate；When VMC runs, institute State cleaning pond and form airtight connection with system, it is characterised in that described cleaning pond is placed with primary efficient filter screen.

In one embodiment, clean and pond is just imitated filter screen for the filter screen having used.Initial effect filtering section is changed After old filter screen carries out simple dedusting, put into cleaning pond.Owing to the dust containing capacity of first effect filter screen is generally large, it can clean to entering The dust in pond effectively adsorbs, and to a certain extent suppression cleaning pond in accumulation dust kicked up when new wind is opened and The secondary pollution causing.In use for some time, directly changing the first effect filter screen in cleaning pond, its Renewal process is more clear Clean cleaning pond is more easy.

By placement just effect filter screen in cleaning pond, the dust containing capacity in cleaning pond can be greatly improved, reduce reentrainment of dust dirt Dye, the clean operation in pond convenient for cleaning, and used just effect filter screen can be recycled, at the base not increasing cost The use intensity of initial effect filtering section filter screen can be reduced on plinth, extend its service life to a certain extent.

In one embodiment, the first effect filter screen in pond is cleaned for horizontally or diagonally placing.

In one embodiment, the first effect filter screen cleaning in pond is single or multiple lift.

In one embodiment, the first effect filter screen cleaning in pond is electrostatic electret material.

In one embodiment, the first effect filter screen cleaning in pond is polypropylene material.

In one embodiment, the first effect filter screen cleaning in pond is open channel structure.

Brief description

The schematic diagram of the VMC that Fig. 1 provides for the utility model embodiment.

Fig. 2 is the open channel structure of a kind of roughing efficiency air filter.

Detailed description of the invention

Seeing Fig. 1, the utility model provides a kind of VMC, and it contains initial effect filtering section (1) and middle high efficiency filter Section (2).There is an ash fall room (3) between initial effect filtering section (1) and middle high efficiency filter section (2), described expansion chamber has One filtering baffle (4) vertical with Leads to new breeze direction, described filtering baffle (4) upper end is fixed on expansion chamber top board, lower end with Expansion chamber floor does not contacts, and the expansion chamber floor between roughing efficiency air filter and filtering baffle is many hole sizers of a horizontal positioned Plate (5)；Expansion chamber floor between filtering baffle and middle high efficiency particulate air filter is a tilted-putted porous sieve plate (6)；Many It is a detachable for cleaning pond (7) below hole sizer plate；When VMC runs, described cleaning pond (7) forms airtight connection with system, Described cleaning pond is placed with primary efficient filter screen (8).

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for this area For technical staff, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, institute Any modification, equivalent substitution and improvement etc. made, should be included within protection domain of the present utility model.
