Abstract
The utility model relates to an air -cooled ash bucket charge level indicator, be equipped with the cooling air transmission pipeline who annotates the wind gap including one end be equipped with a connecting flange on the cooling air transmission pipeline, a diaphragm sensor is connected to cooling air transmission pipeline one end, and the other end is equipped with diffusion silicon pressure sensor, still be equipped with the pressure sensing capillary in the cooling air transmission pipeline, in pressure sensing capillary one end was in the diaphragm sensor, the other end was in in the diffusion silicon pressure sensing ware, it has the oil filler point to open on the pressure sensing capillary that lies in diffusion silicon pressure sensor side. The utility model discloses the air -cooled ash bucket charge level indicator of scheme, by freezing wind transmission pipeline let in the cooling air, and cooling diaphragm sensor keeps stability of measuring tool, and the cooling effect is obvious, has improved the adaptability of level sensor to high temperature.
Description
Technical field
The utility model relates to a kind of material-level measure meter, is specifically related to the air-cooled ash bucket charge level indicator in a kind of measurement coal-burning power plant.
Background technology
In coal-fired power plant, in order to reduce environmental pollution, improving economy, generally all Dry-ash System being carried out, to carry out integrated application to the flyash that coal fired power generation produces.What the application of Dry-ash System technology was maximum is the ash disposal of concentrated phase malleation, namely collects flyash by ash bucket, utilizes pressurized air, storehouse pump and pipeline to carry out ash transfer; It is malleation concentrated phase that whole course of conveying requires, so that the wearing and tearing improving transfer efficiency and reduce conveyance conduit.It is extremely important that storehouse pump fills grey level gauging, and storehouse pump dress ash is few, and belong to the defeated ash of dilute phase, defeated grey efficiency is low, pipe wear is serious; How storehouse pump has filled ash, causes system overload, line clogging, cannot normal defeated ash.In recent years, along with the input of the environmental protection facilities such as coal-burning power plant's denitration, for reducing the wearing and tearing to denitrification apparatus, require more and more higher to the economizer hopper before denitrification apparatus, the ash disposal of denitration ash bucket; Because this region flue dust temperature is at 350-400 DEG C, the flyash temperature fallen is at 300-350 DEG C, and high temperature causes ash bucket material level or storehouse pump level gauging abnormal difficult, causes ash handling equipment to run abnormal.
Utility model content
The utility model object provides that a kind of reliability is high, coal is adaptable to overcome the deficiencies in the prior art, improves the air-cooled ash bucket charge level indicator of level sensor to the adaptive faculty of high temperature.
For achieving the above object, the technical solution adopted in the utility model is: a kind of air-cooled ash bucket charge level indicator, comprises the cooling air transmission pipeline that one end is provided with note air port, described cooling air transmission pipeline is provided with a connecting flange; Described cooling air transmission pipeline one end connects a membrane sensor, and the other end is provided with diffusion silicon pressure sensor; Pressure sensing kapillary is also provided with in described cooling air transmission pipeline; Described pressure sensing kapillary one end is in membrane sensor, and the other end is in diffusion silicon pressure sensor; The pressure sensing kapillary being positioned at diffusion silicon pressure sensor side has oil hole.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The air-cooled ash bucket charge level indicator of the utility model scheme, in use, because the highest Long-term service temperature of the inner silicone oil of diaphragm pressure transducer is less than 250 DEG C, and flyash temperature, generally at 300-350 DEG C, for the applied at elevated temperature environment of level-sensing device, passes into cooling air by cooling air transmission pipeline in this level-sensing device in economizer, denitration ash bucket, storehouse pump, cooling effect is obvious, improve the adaptive faculty of level sensor to high temperature, ensure the accuracy measured, reliability is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of air-cooled ash bucket charge level indicator of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1 be the air-cooled ash bucket charge level indicator of one described in the utility model, comprise one end be provided with note air port 5 cooling air transmission pipeline 2, described cooling air transmission pipeline 2 is provided with a connecting flange 4; Described cooling air transmission pipeline 2 one end connects a membrane sensor 1, and the other end is provided with diffusion silicon pressure sensor 7; Pressure sensing kapillary 3 is also provided with in described cooling air transmission pipeline 2; Described pressure sensing kapillary 3 one end is in membrane sensor 1, and the other end is in diffusion silicon pressure sensor 7; The pressure sensing kapillary 3 being positioned at diffusion silicon pressure sensor 7 side has oil hole 6.This level-sensing device in use, because the highest Long-term service temperature of the inner silicone oil of diaphragm pressure transducer is less than 250 DEG C, and in economizer, denitration ash bucket, storehouse pump flyash temperature generally at 300-350 DEG C, for the applied at elevated temperature environment of level-sensing device, in this level-sensing device, pass into cooling air by cooling air transmission pipeline, cooling effect is obvious, improves the adaptive faculty of level sensor to high temperature, ensure the accuracy measured, reliability is high.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
