The dust generated by the demolition of urban buildings is fast, has strong burstiness, fine particles, long suspension time under outdoor conditions, large pollution range and difficult control.

The dust concentration in the atmosphere environment is specifically limited by the current standards of GBZ1-2010 industrial enterprise design sanitation standard, industrial three wastes discharge trial standard and atmospheric environmental quality standard in China, and the dust concentration in the air of a demolition construction site is far beyond the standards. GB/T50905-2014 green construction specifications of constructional engineering are promulgated by the national housing and urban and rural construction department in the early 2014, and the standards clearly require that the demolition project should collect, filter and the like dust generated by demolition.

The method has the advantages of researching dust characteristics and filtering technology, solving the problem of dust removal in cities, and having profound value and practical significance for protecting the health and environment of people.

Disclosure of Invention

The invention aims to provide a dust collection system for a building demolition construction site, which can solve the problem of dust generated in the process of demolishing urban buildings.

The invention is realized in this way, a dust collecting system for a building demolition construction site, which comprises a plurality of dust collecting devices, wherein the dust collecting devices are distributed around a demolished building; each dust suction device comprises a filter layer arranged at the front end and a fan arranged at the rear end; wherein, the filter layer is by preceding to back including reinforcing bar net, wire net and filter cloth in proper order.

Furthermore, gaps are reserved among the reinforcing mesh, the steel wire mesh and the filter cloth respectively; and a containing groove for loading dust is arranged under the filter layer.

Furthermore, the dust collection system also comprises a linkage controller, and the linkage controller is electrically connected with the fans of the dust collection devices; and the linkage controller is used for controlling the starting and the stopping of each fan and the power during working.

Furthermore, the dust suction device adopts a modular design, and a lifting lug for lifting is arranged at the top of the dust suction device.

Furthermore, the length and the height of the dust suction device are not less than 12 meters.

Compared with the prior art, the invention has the beneficial effects that:

the invention provides a dust collection system for a building demolition construction site, which comprises a plurality of dust collection devices distributed around a demolished building; each dust suction device comprises a filter layer arranged at the front end and a fan arranged at the rear end. The fan can produce powerful negative pressure, with the dust suction device in, the filter layer in the device can play the effect of collecting and filtering the dust.

The filter layer sequentially comprises a reinforcing mesh, a steel wire mesh and filter cloth from front to back; the reinforcing bar net can prevent that big stone that splashes from pounding dust extraction, and the wire net can play the effect of elastic buffer, not only can block little stone, can also prevent that little stone from directly striking the filter cloth to the effect of protection filter cloth and fan has been played. The filter cloth can block fine dust (such as PM 2.5). Therefore, the air exhausted from the rear end of the device can meet the emission requirement, and the dust is prevented from influencing the surrounding environment and the physical health of people.

Gaps are reserved among the reinforcing mesh a, the steel wire mesh b and the filter cloth c respectively. A containing groove e for loading dust is arranged right below the filter layer 11. The dust of the different particle diameters that each space was collected all can drop to storage tank e in, the follow-up unified processing of being convenient for, simultaneously, also avoids the dust too much, blocks up filter layer 11.

Further, the dust collection system also comprises a linkage controller 2, and the linkage controller 2 is electrically connected with the fan 12 of each dust collection device 1; the linkage controller 2 is used for controlling the starting and stopping of each fan 12 and the power during working.

In order to facilitate the installation of the dust collector 1, the dust collector 1 adopts a modular design, and a lifting lug for lifting is arranged at the top of the dust collector.

In the present embodiment, the length and height of the dust suction device 1 are not less than 12 meters.

In the dust suction system of the present embodiment, dust suction devices 1 are provided around the removed building 200, respectively.
