Abstract
The utility model provides an ash storehouse cleaning device, it constitutes to unload grey negative pressure subtotal negative pressure pipe network part two parts including grey storehouse, grey negative pressure part is unloaded including the dust exhaust fan in the ash storehouse, the dry dust tripper, the supporting dust exhaust fan entry of dry dust tripper is equipped with two electric valve, one is the electric valve on the main line, another is the electric valve on dust exhaust fan and the dry dust tripper connecting line, negative pressure pipe network part is including female pipe of negative pressure pipe network and terminal sweeper, establish the shutoff ball valve between female pipe of negative pressure pipe network and the terminal sweeper. The utility model discloses the negative pressure of utilizing the supporting dust exhaust fan entry of dry dust tripper in the grey storehouse system of unloading is accomplished grey storehouse and is unloaded grey workshop negative pressure and clean. The effect of dust exhaust fan in the dry dust system of unloading utilizes the negative pressure principle to collect during the dry dust tripper is unloading the subaerial raise dust of grey process and discharging grey storehouse, extended the working range of dry dust tripper dust exhaust fan, cooperate reasonable negative pressure pipe network clean whole grey storehouse unload grey workshop unload grey in -process raise dust, the dirt that overflows, greatly improve grey storehouse and unload grey workshop operating environment.
Description
Technical field
The utility model relates to a kind of clearing apparatus, especially relates to the clearing apparatus of the airborne dust of the warehouse class storage silo (tank) such as the grey storehouse of the relevant enterprises such as a kind of thermal power plant, metallurgy, mine, iron and steel, slag storehouse and limestone powder bin, excessive dirt etc.
Background technology
In recent years, along with coal fired boiler of power plant dry ash is high with its economic value added, comprehensive utilization wide ranges, social benefit is remarkable, and this ash disposal mode more and more obtains the accreditation of generation investment company.Thermal power plant's dry ash generally adopts Pneumatic ash conveying mode to deliver to grey storehouse and stores, and adopts dry ash or wet grey discharge way entrucking or adopts other mode of movements to deliver to comprehensive utilization user.Because the reasons such as ageing equipment, operation, management also exist mechanicalness airborne dust, excessive dirt in the process of grey storehouse discharging, if things go on like this cause Xie Hui workshop, grey storehouse and zero meter, grey storehouse lamination ash very serious, grey base area dust pollution question is very outstanding; Grey base area is generally arranged in plant area of thermal power plant periphery in addition, and prevention and control management and control supervision is poor, and Ash base area dust pollution is serious in the course of time.At present because grey base area dust pollution is serious, cause grey storehouse to unload grey workshop condition protection problem and give prominence to, Xie Hui workshop, grey storehouse airborne dust problem has become the key issue that many thermal power plants are eager to solve.
Summary of the invention
The purpose of this utility model is to provide a kind of environment friendly and pollution-free grey storehouse clearing apparatus, to overcome the deficiency that prior art exists.
For achieving the above object, the utility model provides a kind of grey storehouse clearing apparatus, comprise grey storehouse and unload grey negative pressure part and negative tube mesh portions two parts, ash storehouse is unloaded grey negative pressure part and is comprised dusting fan, dry ash discharger, dusting fan is connected by pipeline with dry ash discharger, negative tube mesh portions comprises negative pressure pipe network mother pipe and some end sweepers, Cutoff ball valve is established between negative pressure pipe network mother pipe and end sweeper, the female pipe of negative pressure pipe network is connected with pipeline by main line, the supporting dusting fan entrance of dry ash discharger is provided with two electrically operated valves, one is the electrically operated valve on main line, another is mounted in the electrically operated valve on pipeline that dusting fan is connected with dry ash discharger.
The utility model utilizes the negative pressure of dry ash discharger supporting dusting fan entrance to complete Xie Hui workshop, grey storehouse negative pressure cleaning.Dry ash discharger is furnished with dusting fan, and the effect of dusting fan in dry ash discharging utilizes principle of negative pressure unloading the ground airborne dust of grey process to collect dry ash discharger and be discharged in grey storehouse; Expand the working range of dry ash discharger dusting fan, coordinate rational negative pressure pipe network to clean Xie Hui workshop, whole grey storehouse and unload airborne dust in grey process, excessive dirt, grey workshop operation environment is unloaded in the grey storehouse of very big improvement, effectively improves surrounding environment, makes it meet the requirement of environmental protection.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model detailed description of the invention.
Detailed description of the invention
With reference to accompanying drawing 1, the utility model comprises grey storehouse and unloads grey negative pressure part I and negative tube mesh portions II two parts, ash storehouse is unloaded grey negative pressure part I and is comprised dusting fan 6, dry ash discharger 7, dusting fan is connected by pipeline 9 with dry ash discharger, negative tube mesh portions II comprises the female pipe 2 of negative pressure pipe network and some end sweepers 4, Cutoff ball valve 3 is established between negative pressure pipe network mother pipe and end sweeper, the female pipe 2 of negative pressure pipe network is connected with pipeline 9 by main line 8, the supporting dusting fan entrance of dry ash discharger is provided with two electrically operated valves, one is the electrically operated valve 5 on main line, another is the electrically operated valve 1 on dusting fan and dry ash discharger connecting line 9.
The supporting dusting fan entrance of dry ash discharger is provided with two electrically operated valves, and the electrically operated valve 5 when grey storehouse discharging on main line is closed, and the discharging of grey storehouse runs; When the discharging of grey storehouse completes, when ash Xie Hui workshop, storehouse needs to clean, electrically operated valve 1 on dusting fan and dry ash discharger connecting line is closed, and grey storehouse negative pressure clearing apparatus is started working, and cleans that airborne dust in grey process is unloaded in grey storehouse, the dirt etc. that overflows is delivered in grey storehouse by dusting fan in the lump and stored.Two cover systems are separate interrelated again, can realize mutual chain use by control system.
