Abstract
The utility model discloses a double-layer access door structure of an electrostatic precipitator, and the double-layer access door structure comprises a middle seat, and is respectively connected with an outer door and an inner door through the middle seat. The double-layer access door structure adopts a double-layer structure, thereby having simple structure and convenient use, being flexibly opened and closed, improving the sealing property and the thermal insulation effect of the access door, being conductive to reducing air leakage rate and preventing dew condensation and dust adhesion. When the electrostatic precipitator works, the double-layer access door structure can prevent the phenomena of dew condensation and creepage of the body structure of the electrostatic precipitator due to air leakage of the access door and protect the normal use of the electrostatic precipitator.
Description
Technical field
The utility model relates to a kind of electric cleaner structure, specifically, relates to the double-deck access door structure of a kind of electric cleaner.
Background technology
Electric cleaner is to receive the dust of catching in the waste gas with the electrostatic depuration method, and its purification work relies on corona discharge electrode and two systems of precipitation to finish.When dusty gas enters the import loudspeaker, after dusty gas is subjected to the adjustment of airflow-distribution board and deflection plate, make air-flow can enter electric field more equably.Under the effect of cross section expansion, air velocity reduces rapidly, and wherein heavier grit just loses speed and settles down.Enter the dusty gas of electric field because corona discharge electrode feeds high voltage direct current, then near corona discharge electrode, produce corona phenomenon, make gas ionization, there are a large amount of electronics and ion in the gas after the ionization, these electronics and ion and the dust that enters electric field combine, make dust particles, charged grit tends to equipment anode (positive pole) and negative electrode (negative pole) under the effect of electric field force, discharging electronics is deposited on the corresponding electrode respectively, by equipment the moon, the rapping of anode vibrated system, make and be deposited on the moon, dust on the positive electrode shakes, and enters flue-dust retainer and emits by ash exhauster, and cleaned gas enters atmosphere.
Electric cleaner in use must be carried out maintenance work, to prolong the service life of equipment.Electric cleaner access door (being commonly called as manhole door) is exactly the usefulness of the maintenance of electric cleaner for convenience.
At present, known access door structure is an individual layer, is made of doorframe, door closure, handgrip.When the door closure of access door was closed, because long-time wearing and tearing, making between asbestos packing in the housing and the door closure had the slit, and easy like this leaking out makes each the parts dewfall in the electric cleaner, makes the electric field short circuit, can't work.Each parts is got rusty, corrosion, thus have influence on service life of electric precipitation.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of the electric cleaner access door existence that has single layer structure now, provide a kind of electric cleaner double-deck access door structure, it is simple in structure, easy to use, can open neatly and close, and seal tightly, can not only prevent that electric precipitation from leaking out, and can guarantee individual operative employee's safety, not creepage.
For addressing the above problem, the utility model adopts following technical scheme:
The double-deck access door structure of a kind of electric cleaner of the utility model, described double-deck access door structure comprises a middle base, connects an external door and an inside door respectively by middle base.
Be provided with earth cable in the described inside door.
Described inside door and external door are made of doorframe, door closure and handgrip respectively, are provided with the asbestos packing sealant between the door closure of described inside door and external door and the doorframe, are provided with pearlite insulating layer between the door closure.
The utility model is provided with a middle base on the basis of inside door, connect an external door by middle base, and inside door and external door form double-deck access door structure like this, and inside door and the space between the external door that middle base connects can prevent convection current effectively.The asbestos packing sealant is all arranged between the door closure of inside door and external door and the doorframe, pearlite insulating layer is arranged between the door closure, two doors can play good sealing function.Be provided with earth cable in the inside door, earth cable can import the earth to electric current, thereby avoids creepage.
The beneficial effects of the utility model are: the utility model adopts double-decker, and is simple in structure, easy to use, can open neatly and close, and improved the sealing and the heat insulation effect of access door, helps reducing air leak rate of air curtain, prevents the sticking ash of dewfall.When electric cleaner is worked, can prevent body construction dewfall, creepage phenomenon that electric cleaner causes because of access door leaks out, ensure the normal use of electric cleaner.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the double-deck access door structure of a kind of electric cleaner of the utility model, described double-deck access door structure comprises a middle base 1, connects an external door 2 and an inside door 3 respectively by middle base.Middle base mainly plays the connection effect, and inside door and the space between the external door 4 that middle base connects can prevent convection current effectively.Described inside door and external door are made of doorframe, door closure and handgrip respectively, be provided with asbestos packing sealant 5 between the door closure of described inside door and external door and the doorframe, be provided with pearlite insulating layer 6 between the door closure, two doors can play sealing function, have guaranteed that electric cleaner body air leak rate of air curtain is less than 3%.Be provided with earth cable 7 in the inside door, earth cable can import the earth to electric current, thereby avoids creepage.
The utility model adopts double-decker, and is simple in structure, easy to use, can open neatly and close, and improved the sealing and the heat insulation effect of access door, helps reducing air leak rate of air curtain, prevents the sticking ash of dewfall.When electric cleaner is worked, can prevent body construction dewfall, creepage phenomenon that electric cleaner causes because of access door leaks out, ensure the normal use of electric cleaner.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
