Description

A kind of novel ash bucket is with being with the air layer steam heater

Technical field

The utility model relates to the electric dust collector technical field, relates in particular to the ash bucket steam heater.

Background technology

In the electric dust collector dust removal process, the collected dust of the dust exhaustor of various types falls into and all has certain temperature in the ash bucket, if the heat tracing effect of ash bucket wallboard is bad, can cause the temperature of ash bucket inwall to be lower than the temperature of dust, local dewfall can make the local caking of the dust in the ash bucket or bridging phenomenon, causes the ash bucket ash discharge not smooth.The mal of ash position improves except the load that increases equipment, also can cause the secondary fly-up of dust, even cause electric dust collector negative electrode short circuit phenomenon, is unfavorable for dusting equipment realization environment protection standard standard.

In the prior art, as shown in Figure 1, steam heating pipe 1 is laid immediately on the ash bucket wallboard outside face, and heat-insulation layer 2 is laid on wallboard and the steam heating pipe 1, is unfavorable for that homogeneous conducts heat and interchange of heat, still can local dewfall and the local caking of dust or bridging phenomenon; The parallel design with horizontal surface of steam heating pipe 1, very easily cause the heating pipe trend inconsistent with current direction during installation, especially in the north, winter temperature is low, during overhaul of the equipments stops air feed, moisture in the steam pipe can not in time be discharged, and leaking except the gas leakage that causes the perforation of heating pipe localized corrosion to cause influences the heat tracing effect, and the accident because of the spalling heating pipe that freezes can take place when serious; As shown in Figure 2, for steam heating pipe admission pipe 6, steam outlet pipe 7 in the prior art and gather pipe 8 and steam heating pipe 1 assembling scheme drawing, its used elbow quantity is many, and the pipeline power-assisted is big.

In view of this, the inventor studies and improves with steam heater electric duster ash bucket, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of novel ash bucket with being with the air layer steam heater, being convenient to homogeneous conducts heat, prevent the generation of the local dewfall of dust and the local caking of dust or bridging phenomenon, solved corrosive pipeline and spalling problem that the heating pipe impeded drainage causes simultaneously.

For achieving the above object, technical solution of the present utility model is:

A kind of novel ash bucket comprises steam heating pipe and heat-insulation layer with band air layer steam heater; The circuitous ash bucket outside face that is layed in of steam heating pipe; Heat-insulation layer is arranged on the outside of steam heating pipe; Heat-insulation layer and ash bucket outside face are provided with cavity, form air layer.

Further, steam heating pipe and horizontal direction are the angle of inclination, and the angle of inclination is 1 °～3 °.

Further, steam heater also comprises reinforced rib, and reinforced rib is fixed on the ash bucket outside face, and steam heating pipe is circuitous to be laid on the reinforced rib.

Further, steam heater also comprises admission pipe, steam outlet pipe and gathers pipe; Admission pipe is layed in the ash bucket side top, forms a close passage around the ash bucket side top, and each steam heating pipe admission port of ash bucket side top communicates with the admission pipe close passage; Steam outlet pipe is layed in ash bucket side lower curtate, forms a close passage around the ash bucket side bottom, and each steam heating pipe steam outlet of ash bucket side bottom communicates with the steam outlet pipe close passage, admission pipe and steam outlet pipe respectively with gather pipe and communicate.

After adopting the utility model structure, the air layer that forms between ash bucket outside face and the heat-insulation layer, play the effect that homogeneous conducts heat, prevent the generation of the local dewfall of dust and the local caking of dust or bridging phenomenon, steam heating pipe and horizontal direction are the angle of inclination simultaneously, can prevent during overhaul of the equipments by actv., moisture in the steam pipe can not in time be discharged, and the gas leakage that causes the perforation of heating pipe localized corrosion to cause is leaked, and influences the heat tracing effect, and prevent from taking place because of the accident of the spalling heating pipe that freezes, in addition, be in charge of to the connection mode that gathers pipe by the reasonable Arrangement steam heating, reduced the quantity of elbow, reduced the pipeline power-assisted, energy-saving and cost-reducing.

The specific embodiment

As shown in Figure 3, the utility model has disclosed a kind of novel ash bucket with band air layer steam heater, comprises steam heating pipe 1 and heat-insulation layer 2.

The steam heating pipe 1 circuitous ash bucket outside face that is layed in, be the angle of inclination with horizontal direction, the angle of inclination is 1 °～3 °, can prevent during overhaul of the equipments by actv., moisture in the steam pipe can not in time be discharged, the gas leakage that causes the perforation of heating pipe localized corrosion to cause is leaked, and influences the heat tracing effect, and prevents from taking place because of the accident of the spalling heating pipe that freezes.

Steam heater also can arrange reinforced rib 3, and reinforced rib 3 is weldingly fixed on the ash bucket side, steam heating pipe 1 circuitous being layed on the reinforced rib 3.

Heat-insulation layer 2 is welded on the outside of steam heating pipe 1 by strut bar 4; Heat-insulation layer 2 is provided with cavity with the ash bucket outside face, forms air layer 5, plays the effect that homogeneous conducts heat, and prevents the generation of the local dewfall of dust and the local caking of dust or bridging phenomenon.

As shown in Figure 4, steam heater also comprises admission pipe 6, steam outlet pipe 7 and gathers pipe 8, admission pipe 6 is layed in the ash bucket side top, form close passage, each steam heating pipe admission port 11 of ash bucket side top communicates with admission pipe 6 close passage, and steam outlet pipe 7 is layed in ash bucket side lower curtate, forms close passage, each steam heating pipe steam outlet 12 of ash bucket side bottom communicates with steam outlet pipe 7 close passage, admission pipe 6 and steam outlet pipe 7 respectively with gather pipe 8 and communicate.Be in charge of to the connection mode that gathers pipe by the reasonable Arrangement steam heating, reduced the quantity of elbow, reduced the pipeline power-assisted, energy-saving and cost-reducing.
