Description

The pulse blowing bag type dust precipitator of big anti-block ash bucket

Technical field:

The present invention relates to a kind of pulse blowing bag type dust precipitator, particularly relate to a kind of pulse blowing bag type dust precipitator of big anti-block ash bucket.

Background technology:

Common employed pulse blowing bag type dust precipitator is in running, dust in the big ash bucket tends to occur dewfall, hardens and the bridging phenomenon, when especially the smoke pollution of high temperature, high humidity and high dew point being handled, thus, the situation that causes the interior dust of collecting of big ash bucket in time not discharged, thereby, influenced the normal operation of pulse blowing bag type dust precipitator, reduced the service life of the filter bag of pulse blowing bag type dust precipitator, and, also increase the workload of the maintenance and the maintenance of equipment, can cause dust pelletizing system in paralyzed state when serious even.

Summary of the invention:

The objective of the invention is to provide a kind of pulse blowing bag type dust precipitator of improved big anti-block ash bucket, it not only can be eliminated formed dewfall in the big ash bucket of pulse blowing bag type dust precipitator effectively, harden and the bridging phenomenon, and, the interior fault-free of big ash bucket of pulse blowing bag type dust precipitator is produced, guarantee that pulse blowing bag type dust precipitator is in normal running status all the time.

The object of the present invention is achieved like this: the pulse blowing bag type dust precipitator of big anti-block ash bucket of the present invention has a big ash bucket, the end, lower end of described big ash bucket is installed on an ash-transmission system that has a unloading valve, be equiped with a casing on the upper end end face of described big ash bucket, end, upper end in the described casing has been separated into a clean room by card with holes, be equipped with a pulse jet part on the upper end end face of described clean room, one sidewall of described casing is provided with dusty gas inlet, one end of described clean room is provided with a purified gas outlet, be provided with and winding-up pipe band spout that be communicated with in the described clean room with the pulse valve of pulse jet part, be installed on the filter bag of band filter bag cage bone in the hole on the bottom surface card of described clean room, the filter bag of band filter bag cage bone is to hang in the casing, be equiped with an ash bucket heat-insulation layer on the inwall of described big ash bucket, be mounted with a heater in the described big ash bucket, also be fixed with an air jet pipe that is being communicated with the puff prot pipe in the described big ash bucket, a described end that stretches out the outer air jet pipe of big ash bucket is connected with an air bubble, the opposite side on the described air bubble and be equiped with a pulse control valve successively, magnetic valve.

The big ash bucket of existing pulse blowing bag type dust precipitator because the present invention has recombinated, in big ash bucket, set up anti-blocking anti-plug device, adopt heat-insulation layer, the dewfall of heater to be produced in the big ash bucket of eliminating pulse blowing bag type dust precipitator, phenomenon hardens, enable air bubble and pass through air jet pipe, the winding-up of puff prot pipe, solve the interior formed bridging phenomenon of big ash bucket of pulse blowing bag type dust precipitator, thereby, fundamentally avoided present employed pulse blowing bag type dust precipitator in running, the fault that is taken place in the big ash bucket, simultaneously, also prolong the service life of the filter bag of pulse blowing bag type dust precipitator widely, really guaranteed the good operation of pulse blowing bag type dust precipitator.

Description of drawings:

Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation of the pulse blowing bag type dust precipitator of big anti-block ash bucket of the present invention.

Fig. 2 is another routine user mode schematic diagram of the pulse blowing bag type dust precipitator of big anti-block ash bucket of the present invention.

The specific embodiment:

Describe the details and the working condition of the pulse blowing bag type dust precipitator of the big anti-block ash bucket that proposes according to the present invention in detail below in conjunction with accompanying drawing.

With reference to Fig. 1, the pulse blowing bag type dust precipitator of the big anti-block ash bucket of this invention is made up of described big ash bucket (1), described casing (4), described clean room (6) and described pulse jet part (7).

Be equiped with an ash bucket heat-insulation layer (12) on the inwall of described big ash bucket (1), be mounted with a heater (13) in the described big ash bucket (1), the optional power taking heater of described heater (13), also can select the steam pipe device for use, also be fixed with an air jet pipe (15) in the described big ash bucket (1), be communicated with puff prot pipe (14) on the described air jet pipe (15), the coconnected puff prot pipe of described air jet pipe (15) (14) uses two at least, according to the practical application needs, perhaps can be more than two, a described end that stretches out the outer air jet pipe (15) of big ash bucket (1) is connected with an air bubble (16), the opposite side of described air bubble (16) is equiped with a pulse control valve (17) successively, magnetic valve (18), the end, lower end of described big ash bucket (1) is fixed with an ash-transmission system (3), the end, lower end of described ash-transmission system (3) is equipped with a unloading valve (2), one casing (4) is installed on the upper end end face of described big ash bucket (1), the clean room (6) that end, upper end in the described casing (4) is separated into by card with holes (5), be equipped with pulse jet part (7) on the upper end end face of described clean room (6), one sidewall of described casing (4) is provided with dusty gas inlet (8), one end of described clean room (6) is provided with a purified gas outlet (9), be provided with an and winding-up pipe (10) that be with spout that be communicated with in the described clean room (6) with the pulse valve of pulse jet part (7), be installed on the filter bag (11) of band filter bag cage bone in the hole on the bottom surface card (5) of described clean room (6), the filter bag (11) of band filter bag cage bone is to hang in the casing (4).

After in the big ash bucket of pulse blowing bag type dust precipitator, having set anti-blocking anti-plug device of the present invention, use described ash bucket heat-insulation layer, heater can make dewfall, the phenomenon that hardens promptly is eliminated in the big ash bucket of pulse blowing bag type dust precipitator, utilize described air bubble by described air jet pipe, the winding-up of puff prot pipe, the interior formed bridging of big ash bucket of pulse blowing bag type dust precipitator is abolished, dust will be got rid of clearly gradually, ensured the normal operation of pulse blowing bag type dust precipitator, thus, thoroughly avoided present employed pulse blowing bag type dust precipitator in running, the dewfall that is taken place in the described big ash bucket, harden and the caused fault of bridging phenomenon, thereby, also prolonged service life of the filter bag of pulse blowing bag type dust precipitator fully.

Anti-blocking anti-plug device of the present invention was both configurable to be used in the big ash bucket of pulse blowing bag type dust precipitator; also can install in other the similar ash bucket of pulse blowing bag type dust precipitator and use; manifested as the routine user mode schematic diagram of Fig. 2, in the scope that all belongs to the present invention and protected.
