Abstract

The utility model relates to an anode pipe bundle for honeycomb-shaped conductive electric demisters for glass fiber reinforced plastic, which has a honeycomb-shaped cross section and is formed by a plurality of glass fiber reinforced plastic pipes with orthohexagonal cross sections. The utility model has no need of an out shell and a pattern pipe, and the utility model has the advantages of compact structure, material saving, small size, light weight, reinforced electric conductivity, fire resistance and corrosion resistance and large effective settling area of electric field. Compared with the existing lead electric demister, the utility model can save 30% of the cost.

Description

The tube bank of honeycomb type electric demisting device with conductive fiberglass reinforced plastic anode

The utility model belongs to a kind of anode tube bank that is used for the electrostatic precipitator of gaseous impurity separation, the anode tube bank in the particularly acid industry fume purifying processes on the employed electrostatic precipitator.

The shell and tube tube bank that existing electrostatic precipitator anode tube bank forms based on lead or PVC-U garden shape pipe, domestic also have minority enterprise to use the anode tube of square tube bank as electrostatic precipitator, the problem of its existence is: they all must adopt card fixed anode pipe, and weight is big, and is yielding; Complex structure; The cost height; And be difficult for making and maintenance, and the anode tube poor electric conductivity of using PVC-U to make, mechanical strength is not high, and is easily aging, and square anode tube bank forms the dead angle easily, and electric field is inhomogeneous, and demist efficient is low.

The purpose of this utility model is exactly that a kind of compact conformation, the conduction fire resistance that design at problems of the prior art are good, long service life, the honeycomb type electric demisting device with conductive fiberglass reinforced plastic anode tube bank that demist efficient is high.

It is that orthohexagonal glass reinforced plastic pipe processes the tube bank that the cross section is a honeycomb type that the utility model adopts several cross sections; Every adjacent regular hexagon tube wall outside has the reinforcement gusset.

This anode tube bank has the following advantages through after the above-mentioned improvement:

(1) owing to adopt honeycomb, positive plate is restrained the intensity height, and is not yielding, can the long-time high-efficiency operation of assurance equipment.

(2) electric conductivity, anti-flammability, corrosion resistance are strengthened greatly, and the effective desilting area of electric field is big.

(3) the utility model need not be provided with shell and card, and compact conformation is saved material, and volume is little, and is in light weight, hangs down 30% approximately than existing plumbous system electrostatic precipitator cost.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Fig. 1 is the sectional view of an embodiment of the present utility model.

Fig. 2 restrains peripheral employed reinforcement sectional view for anode.

Present embodiment is the honeycomb type anode tube bank that is processed by seven glass reinforced plastic pipes, the inscribe garden diameter of phi 300MM of every single tube 1, and length is 4500MM.

In the present embodiment, as shown in Figure 2, it is material with hardwood that its anode is restrained peripheral employed gusset 2, by binding agent and adjacent two regular hexagon glass reinforced plastic pipe outer walls bonding, bonding part glass reinforced plastic pipe wall thickness 3MM, all the other thickness of pipe wall 6MM; Flange is special is connected for this anode tube bank and last lower chamber employing; the anode card of two ends up and down of conventional use and the protection housing of pipe have been cancelled; this system is by test; record electric demisting device with conductive fiberglass reinforced plastic demist stabilised efficiency more than 96.5%; when gas flow rate reached 1.2M/S in electric field, acid mist content was lower than the former production control index 0.03g/Nm of the Ministry of Chemical Industry in the electric demisting device with conductive fiberglass reinforced plastic exit gas ³At the nearly 2g/Nm of inlet gas acid mist content ³Situation under, acid mist content is lower than the production control index equally in its exit gas; Individual data even reach the production control index 0.005g/Nm of two-stage electrostatic precipitator ³

Compare with the plumbous electrostatic precipitator of handling the same property furnace gas, under the condition of same electric field velocity of flue gas, acid mist content only is the former 1/3rd in the electric demisting device with conductive fiberglass reinforced plastic exit gas.

By top analysis as can be known, the honeycomb type electric demisting device with conductive fiberglass reinforced plastic has the gas flow of processing fire, and the advantage that demist efficient is high has broad application prospects in gas washing in SA production.
