Abstract
The utility model relates to a spraying dust suppression device specifically is an automatic dust suppression device that sprays of blast furnace top hopper. Including the dust cage body, permanent pressure water pump, constant voltage air feeder, supply channel, air supply line, spray pipe passage, atomizing nozzle and controller, still include the gentle fog generator of electric valve group, the supply channel is do not passed through to the electric valve component and air supply line is connected with permanent pressure water pump and constant voltage air feeder, and electric valve group is connected with the controller through control cable, gas fog generator passes through supply channel and air supply line and electric valve group link respectively, and atomizing nozzle sets up on gas fog generator. The utility model discloses a control system control electric valve group realizes automatic spraying, simple structure, and the practicality is strong, and the dust collection efficiency can effectively reduce the pollution of dust up to more than 96%, has satisfied the requirement of environmental protection.
Description
Technical field
This utility model relates to spray dust-arrest device, specifically a kind of blast furnace roof hopper auto spraying dust-arrest device.
Background technology
Research for Feeding Raw Materials System many employings truck formula feeder, when raw material is poured into blast furnace hopper by feeding cart, contamination by dust and serious, dissipate through wind aloft, form floating dust, environmental effect is severe, but there is presently no one can direct applied Environmental-protection dust removal device, this is the blind spot of steel plant's environmental protection.
Utility model content
This utility model aims to solve the problem that the problems referred to above, thus providing a kind of simple in construction, practical blast furnace roof hopper auto spraying dust-arrest device.
This utility model solves described problem, the technical scheme is that
A kind of blast furnace roof hopper auto spraying dust-arrest device, including dust cover body, constant voltage water pump, constant pressure air feeding device, supply channel, supply air line, atomizer passgae, atomizer and controller, also includes electrically operated valve group and aerosol generator；Electrically operated valve group is connected with constant voltage water pump and constant pressure air feeding device respectively through supply channel and supply air line, and electrically operated valve group is connected with controller by controlling cable；Aerosol generator is connected with electrically operated valve group respectively through supply channel and supply air line, and atomizer is arranged on aerosol generator.
Adopting this utility model of technique scheme, compared with prior art, its prominent feature is:
1. control electrically operated valve group by controller and realize auto spraying, simple in construction, practical.
2. efficiency of dust collection may be up to more than 96%, effectively reduces the pollution of dust, meets the requirement of environmental protection.
As preferably, this utility model further technical scheme is:
Controller is connected to skip car position detector by controlling cable, can monitor the position of skip car in real time, produces discontinuity with flue dust and carries out spray for dust suppression, water-saving and electricity-saving.
Aerosol generator is arranged on side in dust gathering arrester body.
Supply channel is provided with water filter.
Supply air line is provided with air filter.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram；
In figure: supply channel 1；Supply air line 2；Water filter 3；Air filter 4；Constant voltage water pump 5；Constant pressure air feeding device 6；Electrically operated valve group 7；Controller 8；Skip car position detector 9；Aerosol generator 10；Dust cover body 11, atomizer 12.
Detailed description of the invention:
Below in conjunction with embodiment, the utility model is described in further detail, and only for purpose of being more fully understood that this utility model content, therefore, the cited case is not limiting as protection domain of the present utility model.
nullReferring to Fig. 1，Electrically operated valve group 7 is connected with constant voltage water pump 5 and constant pressure air feeding device 6 respectively through supply channel 1 and supply air line 2，Supply channel 1 is provided with water filter 3，Supply air line 2 is provided with air filter 4，Electrically operated valve group 7 electrically connects with controller 8 by controlling cable，Aerosol generator 10 is arranged on the position that relative flue dust inside dust cover body 11 is easiest to be removed，Aerosol generator 10 is connected with electrically operated valve group 7 respectively through supply channel 1 and supply air line 2，Atomizer 12 is arranged on aerosol generator 10，Aerosol generator 10 can flow to according to flue dust、The size of soot dust granule、The difference of total fume amount，Change aerosol injection direction、The aerosol particles size of injection and the atomizer 12 changing different aerosol amounts，Controller 8 is connected to skip car position detector 9 by controlling cable，Skip car position detector 9 is for detecting the position of feeding cart，Positional information is fed back to controller 8，Controller 8 completes a spray for dust suppression by controlling electrical valve group 7.
The efficiency of dust collection of this device may be up to more than 96%, and the position of skip car can be monitored in real time, discontinuity carries out spray for dust suppression, not only effectively reduce the pollution of dust, meet the requirement of environmental protection, moreover it is possible to save a part of electric energy, applied widely, it is used not only for the dedusting of blast furnace roof hopper, it is also possible in the dedusting of skip car when filling with substance.
The foregoing is only the embodiment that this utility model is preferably feasible, not thereby limit to interest field of the present utility model, the equivalence change that all utilization this utility model description and accompanying drawing content thereof are made, it is both contained within interest field of the present utility model.
