Abstract

The utility model relates to a top de-smoke treating apparatus comprising an air-scoop, a tortuous strengthen contactor, a sprinkle-nozzle, a gas outlet, a dirt discharge nozzle, a gas water separator and etc. The tortuous strengthen contactor(2) and the gas water separator(7) are arranged from top to bottom. A dehydrating board is arranged the nether shell from the middle to the top and distribute in the connective two canisters. Compare with the double-tube dust catcher in existence, the utility model has the advantages of avoiding air leak and water leak and having a beautiful appearance. Compared with the drying double-tube dust catcher, the utility model can improve the efficiency from ninety percent to ninety nine percent and the desulfurization efficiency is improved from zero to eighty five percent.

Description

Top flue gas removing washer

The utility model relates to a kind of desulfation dust-extraction device, belongs to coal-fired flue gas desulfurization dedusting and industrialness elimination of dust contamination technical field.

Existing common desulfurizing dust-collector has several types such as the bitubular, Venturi tube, dry type multitube, but its desulfurization dust-removing efficiency is lower, along with improving constantly of environmental requirement, can't meet the demands fully, and these equipment overwhelming majority is piled up by natural granite and forms, therefore when handling high-temperature flue gas, usually split to cause and leak, equipment can not be run well, and cause surrounding environment to pollute.

The purpose of this utility model is to produce a kind of efficient, low energy consumption, and does not have desulfurating dust-removing equipment---the top flue gas removing washer of defectives such as leaking.

For achieving the above object, the utility model by the following technical solutions:

Wet type top flue gas removing washer, by tangential or axial admission mouth, be folded to water conservancy diversion and strengthen contactor, shower nozzle, tangential gas outlet, sewage draining exit, moisture trap etc. and constitute, being folded to water conservancy diversion reinforcement contactor (2) and moisture trap (7) arranges from top to bottom, dewatering plate (11) is installed in goes up the position in the lower case, and is distributed in interior composition of two tubes of connection;

Upper body (1) center arrangement subtend shower nozzle (4) and top shower nozzle (5);

Lower case (8) top is provided with tangential outlet, and the bottom is provided with the connection conical bottom.

Adopt import special stainless steel circular upper cover, going to the bottom is pyramidal structure;

The utility model is compared with the existing bitubular, venturi tubing deduster, phenomenon such as leak that can avoid leaks out, and good looking appearance is light and handy, compares with the dry type multi-tube dust cleaner, efficiency of dust collection can be brought up to more than 99% from 90%, and desulfuration efficiency can be brought up to more than 85% from 0.

Further specify the utility model below in conjunction with drawings and Examples.

Fig. 1 is the profile of the utility model top flue gas removing washer;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is folded to the schematic diagram that water conservancy diversion is strengthened contactor;

Fig. 4 is the centrifuge dehumidifier schematic diagram.

Upper body 1 includes one and is folded to water conservancy diversion reinforcement contactor 2, coal-fired flue-gas or industrial waste gas tangentially or axially enter upper body 1 by gas approach 3, enter the water conservancy diversion that is folded to that is installed on the upper body 1 respectively and strengthen contactor 2, behind contactor 2, form the high speed swirling eddy, the water (or alkali lye) that the shower nozzle 6 at transition conduit 4 center subtend shower nozzles 5 and upper body top is supplied with external water pipe in the middle part of being arranged on sprays in the air-flow of rotation at a high speed, water is along with the rotation at a high speed of flue gas stream, oarse-grained water and grit are thrown to upper body 1 inwall and form moisture film under action of centrifugal force, flow to the inner core 7 that links to each other with transition conduit 4 bottoms, carrying out once more centrifugal rotation extends contact time, then through being located at the moisture trap 8 that links to each other with inner core 7 bottoms, by its centrifugal action water and dirt are thrown to lower case 9 inwalls, the sewage draining exit 11 that flow to the conical bottom 10 that links to each other with lower case 9 along inwall flows out, and reaches the purpose of high efficiency desulfurization and dedusting.

The separated device 8 of air-flow is folded to behind the water conservancy diversion and rises along lower case 9 inwalls, again through dewatering plate 12 interception dehydrations, reaches the purpose of good gas-water separation.Dry flue gas is discharged by the tangential gas outlet 13 at lower case 9 tops.

Preferred embodiment of the utility model is that external application special stainless steel (special metal material) is made in the overall structure, upper body 1 inwall granite liner, and smoke air inlet 3 adopts tangential or axial arranged, and the inner core of time expand is set in the lower case 9.
