Description
Technical field
The utility model relates to a kind of device that is used for the semi-dry desulphurization system, particularly a kind of absorbent metering and conveying device that is applied to the semi-dry desulphurization system.
Background technology
In the semi-dry process flue gas desulphurization system, the consumption of accurately measuring desulfurization absorbent is to guarantee the key of desulfurization economy, efficient, stable operation, also is the key foundation of assessment examination desulphurization system overall performance.National environmental protection portion does in [2009] No. 8 files at ring and also explicitly calls for desulphurization system need write down the data such as consumption of continuous flue gas monitoring data and desulfurization absorbent, reduces discharging verification calculation work [1] to strengthen coal-fired flue gas desulfurization facility sulfur dioxide.Therefore, the semi-dry process flue gas desulphurization system must dispose a reliable and stable desulfurization absorbent metering transmission system.
At present, the metering of absorbent and transmission are separate operation, therefore, use comparatively trouble.And metering is to adopt belt scale, and there is following problem in conventional belt scale: the 1. easy sideslip of belt; 2. the desulfurization absorbent storehouse blocks belt when descending ash in a large number easily; 3. measure not accurate enough.Therefore, be difficult to satisfy the requirement of semi-dry process flue gas desulphurization system.
The utility model content
The purpose of the utility model is, a kind of absorbent metering and conveying device that is applied to the semi-dry desulphurization system is provided.The utlity model has easy to use, fault rate is low and measure accurate characteristics.
The technical scheme of the utility model: a kind of absorbent metering and conveying device that is applied to the semi-dry desulphurization system; It is characterized in that: comprise the little storehouse of buffering; Buffering Xiao Cang bottom is provided with the sensor weighing device; Cushion below, little storehouse and be connected with star-like dispenser, jet pump in turn, jet pump one end connects roots blower, and the other end connects desulfurizing tower.
In the aforesaid absorbent metering and conveying device; Described sensor weighing device comprises the bearing that is used to support the little storehouse of buffering; Be provided with LOAD CELLS through support member under the bearing, LOAD CELLS through signal cable connect the sensor terminal box successively, weigh display instrument and computer.
In the aforesaid absorbent metering and conveying device, described LOAD CELLS is a resistance strain weighing transducer.
In the aforesaid absorbent metering and conveying device, be provided with manual push-pull valve between little storehouse of described buffering and the star-like dispenser.
In the aforesaid absorbent metering and conveying device, be provided with expansion joint between described star-like dispenser and the jet pump.
Compared with prior art; The utility model combines the metering and the conveying of disposable completion absorbent with weighing device with transmitting device, use and become particularly convenient, adopts the sensor weighing device to measure simultaneously; Fault rate obviously reduces, and the accuracy of metering is high.
The utility model also has following characteristics:
1. because system is provided with the little storehouse of buffering, the stop of desulfurization absorbent in the little storehouse of buffering is shorter, has effectively reduced phenomenons such as powder canopy storehouse;
2. because whole powder course of conveying all is airtight, leakage material, the dust raising phenomenon that possibly occur in the feeder process have been reduced;
3. the sensor weighing device is good to the material controllability, can move steadily in the long term;
4. easy to use, the technical maturity of resistance strain weighing transducer, stable and reliable for performance, highly sensitive, measuring speed fast, be fit to static state and kinetic measurement, is easy to realize the automation and the multiple spot synchro measure of measuring process;
5. stable and reliable operation, desulfuration efficiency also is stabilized in more than 90% when guaranteeing system economy, satisfies the overall performance index request of semi-dry process flue gas desulphurization system.
