Description

Efficient spraying dust fall fence

Technical Field

The utility model relates to a device of water spray curtain dust fall especially relates to an efficient spraying dust fall fence.

Background

During the construction process, a large amount of dust can be generated no matter earthwork is excavated, cement is loaded and unloaded, vehicles run or powder is carried. These fly dusts generally contain silica, and cause silicosis by long-term inhalation, so that the fly dusts need to be treated.

The dust at the treatment site is similar to the treatment noise and mainly comprises the following three aspects: firstly, the generation of dust is inhibited, so that during construction of a construction site, water is sprayed on the ground to inhibit the dust from being generated during the activities of vehicles and personnel; secondly, the spread of the flying dust is inhibited, and dust particles collide with fog drops by spraying the flying dust on the site in a large range by using a fog gun or other spraying devices, so that the dust particles are carried by the fog drops and land on the ground; and thirdly, preventing workers from inhaling raised dust by wearing labor tools such as a breathing mask and the like.

However, these dust-proof measures are only used on the construction site, and the dust will fly out of the construction site under the air, causing damage to residents and pedestrians who have no provisions. And the raised dust is completely pressed on the construction site, so that the raised dust does not appear in the air, which is obviously impossible. However, the dust itself is denser than air and therefore need only be limited to a certain height above the ground so that it does not harm people around the site.

The utility model discloses a dust suppression device, including the spraying dust fall fence, the spraying dust fall fence is used for carrying out the spraying on the ground, and the spraying dust fall fence is used for carrying out the spraying on the ground. However, most of the raised dust still stays in the air and still can fly high under the drive of the wind.

The technical problem to be solved is that: the current spraying dust fall fence can only press raised dust within a certain height range from the ground and can not effectively remove dust.

In order to solve the technical problem, the utility model adopts the following technical scheme:

an efficient spraying dust-settling fence comprises a support arranged on an installation base surface and atomizing nozzles hung below the support, wherein the atomizing nozzles are communicated with a water supply pipe network through pipelines, the atomizing nozzles are arranged in two parallel rows below the support, openings of the atomizing nozzles are arranged in an oblique lower direction, and the openings of the two atomizing nozzles in different rows are crossed;

a wetting layer for absorbing dust particles is paved on the installation base surface below the atomizing spray head, and a coarse pore channel layer for guiding dust-containing air to enter the wetting layer is paved on the wetting layer.

Further, the openings of the atomizing nozzles in the same row are oriented parallel and coplanar with each other.

Furthermore, the atomizing spray head is arranged on the annular pipe network, and two points which are farthest away from the annular pipe network are respectively communicated with the water supply pipe network.

Furthermore, the coarse pore channel layer is a plurality of layers of mesh sheets which are overlapped up and down, and the meshes on each mesh sheet are arranged in a staggered mode.

Furthermore, the net sheets are plastic-impregnated steel wire net sheets.

Further, the support is a folding split heads.

Further, the wetting layer is a black core cotton felt.

The utility model relates to an efficient spraying dust fall fence compares with prior art, has following beneficial effect:

in the utility model, the two rows of atomizing nozzles are arranged in the direction of crossing each other, so that the air driven by the atomizing nozzles is crossed with each other, thereby increasing the turbulent motion degree of the air, increasing the probability of collision between fog drops and dust particles, and improving the dust removal effect;

the utility model discloses in, through laying the mutual staggered net piece of multilayer in atomizer below, form the coarse pore road layer similar to wire mesh packing, behind the dusty air entering coarse pore road layer, the dirt grain bumps with moist net piece and is stuck, and the dusty air flow is cut apart into slight stream simultaneously, and the wetting layer below the net piece is inclined to scatter around when bumping, and wherein dirt grain is just stuck by the wetting layer more easily.

Detailed Description

As shown in fig. 1, an efficient spray dust-settling fence comprises a bracket 1 arranged on an installation base surface and atomizing spray heads 2 hung below the bracket 1, wherein the atomizing spray heads 2 are communicated with a water supply pipe network through pipelines, the atomizing spray heads 2 are arranged in two parallel rows below the bracket 1, openings of the atomizing spray heads 2 are arranged obliquely downwards, and the openings of the two atomizing spray heads 2 in different rows are crossed; after the shower nozzle is crossed, the air that its drove also can appear intercrossing to increase the turbulent motion degree of air, increase droplet and the chance that the dust particle collided each other, thereby promote dust removal effect.

A wetting layer 4 for absorbing dust particles is paved on the installation base surface below the atomizing spray head 2, and a coarse pore channel layer 3 for guiding dust-containing air into the wetting layer 4 is paved on the wetting layer 4.

As shown in fig. 2, the openings of the atomizing nozzles 2 in the same row are oriented parallel to and coplanar with each other. Therefore, the air driven by the two rows of atomizing nozzles 2 can be fully crossed, and the installation is more convenient.

As shown in fig. 3, the atomizing nozzle 2 is disposed on the circular pipe network 21, and two points on the circular pipe network 21 which are farthest away are respectively communicated with the water supply pipe network. Compared with a tree-shaped structure, the water supply structure enables all the spray heads to obtain uniform and consistent water pressure more easily, and the reliability is higher.

The coarse pore channel layer 3 is a plurality of layers of mesh sheets which are overlapped up and down, the meshes on each mesh sheet are arranged in a staggered mode to form the coarse pore channel layer 3 similar to a metal wire mesh filler, dust particles collide with the wetted mesh sheets and are adhered to the wetted mesh sheets after dust-containing air enters the coarse pore channel layer 3, meanwhile, the dust-containing air flow is split into fine streams which tend to be scattered when colliding with the wetted layer 4 below the mesh sheets, and the dust particles are easily adhered to the wetted layer 4. Care is taken not to stack the webs in an aligned up and down configuration so that the chance of dust particles colliding with the wetted web is reduced and the dusty air is not effectively split.
