Wet dust suppressor for use at circulating air outlet of road sweeping equipment

Abstract

The invention discloses a wet dust suppressor for use at a circulating air outlet of road sweeping equipment. The wet dust suppressor comprises a suction nozzle, a suction tube, a back-blowing tube, a fan and a refuse box. An air passage used for discharging part of dust-bearing air is connected to the back-blowing tube and is provided with a spray dedusting and water recycling unit. The wet dust suppressor has the advantages that secondary pollution by raised dust occurring in cleaning operation of the road sweeping equipment is avoided, dedusting is effective, circulating water is utilized, and spray dedusting is effective.

Description

technical field [0001] The invention belongs to the technical field of road-sweeping and dust-removing equipment, and in particular relates to a wet-type dust-reducing device for a circulating air outlet of road-sweeping equipment. Background technique [0002] At present, the existing road sweeping equipment on the market, including road sweepers and road sweepers, etc., their cleaning operations to prevent dust pollution can be summarized into the following three methods: [0003] (1) Wet dust reduction, spraying water in front of the brush, suction port, suction pipe, and dustbin to reduce dust, the fan directly sucks the garbage into the dustbin from the suction port, and the gas after dust reduction is directly discharged by the fan; the disadvantages of this type of dust reduction: Because the sprayed water cannot be recycled, and in order to ensure the volume of the garbage bin, the volume of the clean water tank is usually relatively small, and the working time must ...

AI Technical Summary

Problems solved by technology

[0003] (1) Wet dust reduction, spraying water in front of the brush, suction port, suction pipe, and dustbin to reduce dust, the fan directly sucks the garbage into the dustbin from the suction port, and the gas after dust reduction is directly discharged by the fan; the disadvantages of this type of dust reduction: Because the sprayed water cannot be recycled, and in order to ensure the volume of the garbage bin, the volume of the clean water tank is usually relatively small, and the working time must be guaranteed, so the amount of water sprayed is relatively small; the suction process must ensure a certain suction force Therefore, the dust suction airflow is relatively fast, and the effect of spraying water and dust during this process is greatly reduced.

[0004] (2) Circulating water for dust reduction, spraying water in the suction port, suction pipe, and dustbin to reduce dust, the sewage flows from the dustbin through the filter screen into the circulating water tank for recycling, and the fan directly sucks the garbage into the dustbin from the suction port, and the gas after dust reduction It is directly discharged by the fan. Although this structure can recycle the sprayed water, thereby increasing the amount of sprayed water and reducing dust, the soil in the garbage bin is brought into the circulating water tank by the sewage, which makes the soil in the circulating water tank have a large amount of sedimentation. Cleaning is quite difficult, all air flow must be exhausted outside, dust removal load

Disadvantages: It is difficult to clean the filter cloth and filter cartridge. After the filter screen and filter cloth in the filter cartridge are blocked, the outlet of the fan will not be exhausted smoothly, which will affect the suction force; the other is to use electrostatic dust removal, and the fan will directly suck the garbage into the garbage from the suction port After entering the box, the fan blows the dusty gas to the electrostatic chamber for dust removal. The air flow rate of this structure is too fast, the dust removal effect is not obvious, the cost and failure rate are high, and the environmental requirements are also high.
