Abstract
The utility model discloses a conveying tank for an ash conveying system. The tank comprises a dome valve, a back pressure valve, a connection tee of an ash conveying pipeline and a conveying tank body; wherein, the dome valve is arranged on a feed hole of the conveying tank body and has the main functions of feeding the conveying tank and sealing the conveying tank body; the back pressure valve is arranged on the top of one side of the conveying tank body for fluidizing fly ash in ash conveying; a grid is arranged on the bottom of the conveying tank body; a hand hole door is arranged on the side wall of the conveying tank body and plugged by a blind flange. When the device runs normally, the situation of ash dropping and whether the ash conveying pipeline is unblocked can be observed. Foreign bodies removed by electrostatic precipitation are obstructed onto the grid and taken out conveniently when the hand hole door on the conveying tank body is opened, while the ash conveying pipeline is not necessary to be dissembled. Testified by production practice, the conveying tank for the ash conveying system can efficiently prevent the foreign bodies from entering the ash conveying pipeline, avoid conveying difficulty and blockage of the ash conveying pipeline, get rid of a big failure affecting the normal operation of the ash conveying system, save various consumption and meanwhile prolong the service life of the device and prevent environmental pollution.
Description
Technical field
The utility model relates to a kind of ash-transmission system equipment of thermal electric generation, and especially a kind of ash-transmission system sends jar.
Background technology
Power plant produces in the electric industry system a large amount of ashes, slag, except that a small amount of ash content exhaust to atmosphere, surplus person delivers to the ash field with ash, slag form by ash disposal system.Ash disposal system is divided mechanical ash disposal (being suitable for the chain furnace of small power plant), pneumatic ash handling and three kinds of technologies of hydraulic(-ash) sluicing.Native system adopts pneumatic ash handling technology, and pneumatic ash removal system is with the collected flying dust of flue-dust retainer under economizer and the electric precipitation, carries by strength to be discharged into grey storehouse, installs to the demand client with automobile fortune then and where handles.Thermal powerplant is failed grey flow process: electric duster ash bucket → transmission jar → ash pipe → grey storehouse → ash field.Sending jar and have crucial meaning whole removing in the ash handing system, mainly is by pressurized air dry ash to be delivered to grey storehouse along ash removal pipe, is storage warehouse and the transmission source that ash-transmission system is carried dry ash and send jar.Because electric dust collector is in operation and falls foreign matter easily, ash-transmission system is when operation, and foreign matter is very easily fallen into and sent jar,, causes carrying mal in ash conveying pipe stenosis jam inside, causes the ash pipe plugging when serious.And when investigation, processing, trouble shooting, wasted great amount of manpower and material resources, financial resources, caused the rising significantly of operation, recondition expense, made the equipment can't economic, safe operation.
Summary of the invention
The utility model is in order to solve the defective that prior art exists, and changes a social system and provides a kind of new ash-transmission system to send jar, can prevent effectively that foreign matter from entering ash pipe, avoids ash conveying pipe difficulty of transportation and plugging, prolongs service life of equipment simultaneously, prevents the pollution of the environment.
The technical solution adopted in the utility model is as follows:
Ash-transmission system sends jar and comprises that dome valve, back pressure valve, ash conveying pipe connect threeway and send tank body, the dome valve is installed in the inlet point place that sends tank body, main effect is that jar feeds in raw material and sealing sends tank body in order to send, back pressure valve is installed in and sends tank body one side roof part, main effect is to make fly ash play rheomorphism when the ash material is carried, and sends tank base and is provided with grate, sends tank wall and has the hand hole door, use the blind plate shutoff, be convenient to the cross-check sum of foreign matter drawn and get.
This ash-transmission system sends a jar process production practice checking, enters ash pipe but actv. prevents foreign matter, has avoided ash conveying pipe difficulty of transportation and plugging, has got rid of a major break down that influences the normal operation of ash-transmission system, has saved every consumption.Prolong the service life of equipment simultaneously, prevented environmental pollution.
Description of drawings
Accompanying drawing is that ash-transmission system sends a jar scheme drawing
The specific embodiment
Introduce embodiment of the present utility model below in conjunction with accompanying drawing:
This ash-transmission system sends jar and mainly is made up of dome valve (1), back pressure valve (2), ash conveying pipe connection threeway (3), transmission tank body (4) etc.Dome valve 1 is installed in the inlet point place that sends tank body 4, and its effect is to feed in raw material for sending jar, and is used as sealing transmission jar when carrying; Back pressure valve 2 is installed in and sends tank body 4 one side roof parts, when carrying, the ash material can make fly ash play rheomorphism, send tank base and be provided with grate (5),, consider to adopt the grate (5) that is spaced apart 60 millimeters more suitable by the size of the foreign matter that comes off (6) is measured calculating; Send the hand hole door (7) that the above 50 millimeters places of tank body 4 sidewall grates have 150 millimeters of diameters, use the blind plate shutoff, be convenient to the cross-check sum of foreign matter drawn and get.
Equipment is normally in service, can observe its fall ash and unimpeded situation of ash pipe, and the electric precipitation foreign matter that comes off is intercepted on the grate, opens the hand hole door that sends on the tank body, can conveniently take out the foreign matter that comes off, and need not open and inspect ash conveying pipe, has improved inspection speed greatly.
Claims (3)
1. an ash-transmission system sends jar, comprise that dome valve, back pressure valve, ash conveying pipe connect threeway and tank body, the dome valve is installed in the inlet point place that sends jar, back pressure valve is installed in tank body one side roof part, it is characterized in that: described transmission tank base is provided with grate, send tank wall and have the hand hole door, use the blind plate shutoff, be convenient to the cross-check sum of foreign matter drawn and get.
2. send jar according to the described ash-transmission system of claim 1, it is characterized in that: described grate adopts and is spaced apart 60 millimeters.
