Description
Technical field
The utility model relates to environmental protection filed of flue gas purification, more specifically, relates to a kind of back suspended hollow seal of desulfurization and wet cottrell of being applied to.
Background technology
Wet electrical dust precipitator employing liquid washes away dust collecting electrode surface and carries out deashing, can effectively collect fine particle (PM2.5 dust, SO3 acid mist, aerosol), heavy metal (Hg, As, Se, Pb, Cr), organic pollution (polycyclic aromatic hydrocarbon, dioxin) etc.Wet cottrell can reach 10mg/m even below 5mg/m because it has after efficient smoke catching efficiency is used wet electrical dust precipitator containing the soot emissions in wet flue gas, dust collection performance and Dust Characteristics are irrelevant, be applicable to the processing containing wet flue gas, be especially useful in the processing of ash-laden gas after power plant, steel mill's wet desulphurization.
Wet cottrell carries out gas cleaning will experience charged, collection and deashing three phases.Wet cottrell is introduced electrode in deduster by external high pressure electric field, makes electrode discharge, thereby makes small dust move deposition to collecting plate, finally by shower water, is rinsed, and completes whole dust removal process.
At present, most of wet cottrells adopt common insulation mode, can cause insulator surface incrustation, easily form short circuit, seriously can cause electric field ground connection, and electric cleaner outage, breaks down.
Utility model content
In order to solve the problem of prior art, to avoid electric cleaner to be in operation and due to insulator surface incrustation, occur the faults such as short circuit, interruption, the utility model provides the hollow seal of a kind of suspension type and wet cottrell.
Described technical scheme is as follows:
On the one hand, the utility model provides a kind of suspension type hollow seal, described device comprises hanging bar and insulator, described insulator forms the cavity axially arranging along it, described hanging bar runs through the cavity of described insulator, and the end of stretching out described insulator, described hanging bar and described insulator matched in clearance, the lateral surface of described insulator is provided with pivot flange.
The periphery of described hanging bar and the formed gap of the inner headed face of described insulator are 40mm.
Described insulator is ceramic insulator.
Described pivot flange is arranged at the middle and lower part of described insulator.
The utility model also provides a kind of wet cottrell on the other hand, comprise shell, be placed in discharge electrode and seal in described shell, the hollow seal of suspension type that described seal is described above, moulding one opening on described shell, described insulator runs through the opening of described shell, described hanging bar is fixedly connected with the electrode framework of described discharge electrode, and described pivot flange is overlapped in the lateral surface of described shell, and forms and be tightly connected with described shell.
The beneficial effect that the technical scheme that the utility model provides is brought is:
A. compared with prior art, the insulator that the utility model provides is hollow-core construction, and hanging bar passes from centre, can prevent from like this hanging bar electric discharge, electric leakage.
B. because all live parts in the utility model are all isolated completely with shell (earth point), be difficult for short circuit.
C. between insulator and shell, form air seal, isolation effect is good, prevents insulator dust stratification, produces short circuit.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is wet cottrell structure chart provided by the utility model.
1-shell, 2-insulator, 3-hangs bar, 4-electrode framework, 5-discharge electrode, 6-opening, 7-pivot flange, 8-cavity.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Consult the hollow seal of suspension type that Fig. 1 provides for the utility model, comprise hanging bar 3 and insulator 2, insulator 2 forms the cavity 8 axially arranging along it, hanging bar 3 runs through the cavity 8 of insulator 2, and the end of stretching out insulator 2, hanging bar 3 and insulator 2 matched in clearance, the lateral surface of insulator 2 is provided with pivot flange 7; Wherein hang the periphery of bar 3 and the formed gap of inner headed face of insulator 2 is 40mm.
Insulator preferably adopts ceramic insulator.Pivot flange 7 is wherein arranged at the middle and lower part of insulator 2.
The utility model also provides a kind of wet cottrell in addition.Comprise shell, be placed in discharge electrode and seal in shell, seal wherein adopts said structure, just repeats no more here.Moulding one opening 6 on shell, insulator 2 runs through the opening of shell 1, and hanging bar 3 is fixedly connected with discharge electrode 5, and pivot flange 7 is overlapped in the lateral surface of shell 1, and forms and be tightly connected with shell 1.
Hanging bar runs through the middle vacancy of insulator, and its upper end is connected with high-tension line, and its lower end is fixedly connected with the fixing electrode framework 4 of discharge electrode 5.
When malleation flue gas enters after wet cottrell, move upward, gas can be full of wet cottrell inside and A, B region, thereby charged hanging bar 3 and outer case of dust remover 1 are separated, and realizes insulation.In addition, in wet cottrell, flue gas also may be full of the space between hollow insulator inwall and hanging bar.
To sum up, gas has played the effect of sealing between wet cottrell housing and hanging bar, even if may having water, wet cottrell inside condenses, but can not between hanging bar 3 and wet cottrell shell, form the continuous globule of continuous conduction, therefore, guarantee insulation, prevent insulator dust stratification, produce short circuit.
Open external high pressure power supply, electric current is guided to high-tension electricity on discharge electrode 5 by electrode framework 4 by hanging bar 3, thereby discharge electrode 5 discharges in wet cottrell.Flue gas after desulfurization is malleation in wet cottrell inside, in the mode of air seal, makes hanging bar 3 insulation in shell 1 and insulator 2, can not cause short circuit.
Above-mentioned the utility model embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
