Description
Technical field
The present invention relates to a kind of sack cleaner, relate in particular to a kind of heating system that is applied to the anti-dust-contained airflow blast of sack cleaner anti-condensation in winter in spring.
Background technology
Sack cleaner is a kind of highly effective dry-type deduster, and the dust layer that forms on filter bag that the dependence fiber filtering is made and the filter bag surface purifies dusty gas.Sack cleaner is for the various dust that produce in the industrial production, and its efficiency of dust collection all may reach more than 99%.If adopt media performance good, structural design, manufacturing and operation are proper, efficiency of dust collection even can reach 99.9%.Over nearly 40 years, because the appearance of new synthetic fiber filter material, updating and the use of control and checkout gear automatically of ash removal method developed rapidly sack cleaner, become the most competitive a kind of cleaner in all kinds of high-effective dust-removing equipment.
But under the winter-spring season low temperature environment, coal yard adopts sack cleaner to remove in the coal dust process, after water content coal dust air-flow enters sack cleaner, is easy to take place dewfall and icing phenomenon.The filter bag dewfall of sack cleaner and freeze after, with the filtering function that completely loses coal dust.Yet, under the condition that does not have the steam source of the gas, adopt the anti-condensation of traditional sack cleaner Electric heating, such as: arrange heater at ash bucket and dust-contained airflow import,, be easy to cause dust explosion accident if heat inhomogeneous and the phenomenon that is short-circuited.
So north spring winter-spring season coal yard rationally adopts sack cleaner insulation and mode of heating, guarantee sack cleaner under working environment below-15 degrees centigrade, still can operate as normal, mine significant to guaranteeing clean and effective.
Summary of the invention
The present invention seeks to propose under the winter-spring season low temperature environment, the heating system of the anti-condensation of coal yard sack cleaner, the blast of anti-freeze and anti-dust-contained airflow guarantees that sack cleaner under working environment below-15 degrees centigrade, still can reach normal dust removing effects.
Technical solution of the present invention is: sack cleaner anti-condensation, anti-freeze safe heating system comprise sack cleaner, pure qi (oxygen) flow export, dividing plate A, winter-spring season pure qi (oxygen) stream branch road, summer and autumn pure qi (oxygen) stream branch road, dividing plate B, summer and autumn pure qi (oxygen) flow export, electric heater, plate type heat exchanger, winter-spring season pure qi (oxygen) flow export, dust-contained airflow inlet, dividing plate C, summer and autumn dust-contained airflow branch road, summer and autumn dust-contained airflow import, winter-spring season dust-contained airflow branch road, dividing plate D, winter-spring season dust-contained airflow import composition.Sack cleaner is connected with the pure qi (oxygen) flow export, the pipeline that connects the pure qi (oxygen) flow export be divided into winter-spring season pure qi (oxygen) stream branch road and summer and autumn pure qi (oxygen) stream branch road, arrange dividing plate A on the winter-spring season pure qi (oxygen) stream branch road, winter-spring season pure qi (oxygen) stream branch road is connected with electric heater, electric heater is connected with plate type heat exchanger, and plate type heat exchanger is connected with winter-spring season pure qi (oxygen) flow export.Also arrange dividing plate B on the summer and autumn pure qi (oxygen) stream branch roads, summer and autumn pure qi (oxygen) stream branch road with summer and autumn the pure qi (oxygen) flow export be connected.Sack cleaner is connected with the dust-contained airflow inlet, the pipeline that connects the dust-contained airflow inlet is divided into summer and autumn dust-contained airflow branch road and winter-spring season dust-contained airflow branch road, arrange dividing plate D on the winter-spring season dust-laden stream branch road, winter-spring season dust-contained airflow branch road is connected with plate type heat exchanger, and plate type heat exchanger is connected with winter-spring season dust-contained airflow inlet.Also arrange dividing plate C on the summer and autumn dust-contained airflow air-flow branch roads, summer and autumn dust-laden stream branch road with summer and autumn dust-contained airflow enter the mouth and be connected.
Sack cleaner may operate under two kinds of patterns, summer and autumn operational mode and winter-spring season operational mode.At different operational modes, the air-introduced machine of sack cleaner can transfer to corresponding power, guarantees air-flow velocity.When winter-spring season temperature is very low, the outer covering and heat insulating layer of sack cleaner, and operate under the winter-spring season operational mode.At this moment, summer and autumn the pure qi (oxygen) branch road and summer and autumn the dust-contained airflow branch road shut by dividing plate B and dividing plate C, the pure qi (oxygen) that is flowed out by the pure qi (oxygen) flow export flows, through winter-spring season dust-contained airflow branch road, entering electric heater is heated, flow through then after heat exchanger and dust-contained airflow carry out exchange heat, discharge, enter in the atmosphere at last by winter-spring season pure qi (oxygen) flow export.Cold dust-contained airflow is flowed into by the import of winter-spring season dust-contained airflow, and after heat exchanger was heated, the dust-contained airflow of flowing through inlet entered sack cleaner.When summer and autumn, temperature was higher, deduster operates under the summer and autumn operational mode, winter-spring season pure qi (oxygen) branch road and winter-spring season dust-contained airflow branch road are shut by dividing plate A and dividing plate D, dust-contained airflow is flowed into by summer and autumn dust-contained airflow import, the summer and autumn dust-contained airflow branch road of flowing through enters sack cleaner by the dust-contained airflow inlet.Pure qi (oxygen) stream by the pure qi (oxygen) flow export flows out through summer and autumn dust-contained airflow branch road, by summer and autumn pure qi (oxygen) flow export discharge, enters in the atmosphere at last.
The invention has the beneficial effects as follows do not having under the explosion caused factor prerequisite of dust-contained airflow, carry out effective electrical heating, to prevent the sack cleaner dewfall, to freeze entering sack cleaner low temperature dust-contained airflow.
