Description

The clean toxic and harmful device of the clean dirt of boiler energy-saving

The utility model relates to the clean toxic and harmful device of the clean dirt of a kind of boiler atomizing backhaul efficient energy-saving.

Existing boiler dusting facility divides dried, wet type two big classes, does not all have the function of the toxic gases such as desulfurization of present urgent need solution.The dry type multi-tube dust cleaner is removed the dirt that gets off by wind meeting dusting polluting environment everywhere, the water deduster of wet type such as numb stone is tall and big, heavy, not attractive in appearance, waste recirculated water, take up an area of many, waste energy, dirt has the possibility of secondary pollution environment often clearly.

The purpose of this utility model be to overcome the weak point in the background technology and provide a kind of volume little, attractive in appearance, economize on water, economize on electricity, save land, energy-conservation, both dedusting can purify the clean toxic and harmful device of the clean dirt of boiler energy-saving of toxic gas, purifying rate height, long service life.

The purpose of this utility model is achieved in that it is made up of dust-cleaning box and clean sulphur device two large divisions, the gas approach of dust-cleaning box is connected with afterbody two return exhanst gas outlet behind the boiler, and the gas vent on the dust-cleaning box is connected with gas passage on the clean sulphur device.Dust-cleaning box is atomizing backhaul dust-cleaning box, be provided with dividing plate in the middle of the casing, casing is divided into two-layer up and down, lower floor is the bitubular, and a layering is provided with porose side by side (porous) curved pipe in the tube, it is the first spraying dust-cleaning device, second dust-cleaning device is positioned at the center of dust-cleaning box and first spraying, and dust-cleaning device is vertical is provided with, and dividing plate is provided with the gas outlet, and the upper strata of dust-cleaning box is provided with first, second two moisture traps, be provided with gas vent at the second moisture trap afterbody, the casing low head is provided with dust-exhausting port; The sulfur purifying chamber that clean sulphur device comprises sulfur purifying chamber, sulfur purifying pool, self-excitation sulfur purifier, moisture trap, sealing is in parallel with uncovered sulfur purifying pool to be one, in establish two self-excitation sulfur purifiers, chemical agent is housed in the sulfur purifying pool, and the moisture trap afterbody is provided with air outlet slit, and outlet links to each other with air-introduced machine.

The purpose of this utility model can also realize by following technical measures: arc side by side porose (porous) pipe of the first spraying dust-cleaning device is 4 row's layering settings, and horizontal arc is 270 degree; Second dust-cleaning device is a cylindrical shape, and the acid-resistant cement that barrel is smeared the 15-25 millimeter with wire netting is made; Moisture trap comprises carriage, separate sheet, and separate sheet is a square, and the gradient that is 45 degree places on the carriage; First, second self-excitation sulfur purifier is a cylindrical shape, and the first self-excitation sulfur purifier is set with the second self-excitation sulfur purifier outward, and first sulfur purifier is apart from 100 millimeters on water seal line, and second sulfur purifier enters following 200 millimeters of water seal line.

The course of work and principle: because air-introduced machine is a negative pressure power, the flue gas of being discharged by afterbody two return behind the boiler enters dust-cleaning box Lower Half gas approach, flue gas enters the first spraying dust-cleaning device that rotates around center second dust-cleaning device from right to left, the water-jet of the first spraying dust-cleaning device ejection flows to second dust-cleaning device and forms the clean dirt of atomizing, and the dirt that purifies is flowed in the automatic de-sludger by dust-exhausting port automatically and takes out of.The used water of the first spraying dust-cleaning device is the secondary water in the scummer, pump into the dirty immersible pump that is located at water level place, scummer top, gas behind the clean dirt enters dust-cleaning box top by the gas outlet on the dividing plate, enter first moisture trap, and then go into second moisture trap, isolated gas enters the net flow chamber through the gas vent of the second moisture trap afterbody gas passage by the net flow device, the medicament that adds clean sulphur detoxification and pernicious gas in the net flow pond, anti-position is the first self-excitation net flow device under the gas passage, the clean sulphur of its chemical from top to bottom self-excitation, the clean sulphur of the chemical from bottom to top self-excitation of the second self-excitation sulfur purifier, air behind the clean sulphur enters moisture trap, the air outlet slit of moisture trap afterbody connects air-introduced machine, and the air-introduced machine rear portion has 2 meters high air exits that cleaned air passes is discharged.

The utility model compared with prior art has following advantage:

1, because the dust-cleaning device of arcs is spent in employing spraying backhaul rotation 270, clean dirt efficient height, the employed water of spraying is the secondary water of using in the scummer, thereby the saving water purification, the dirt of purification flows into the slagging-off troughed belt automatically and goes out, and need not clear up;

2, sulfur purifying chamber, sulfur purifying pool, self-excitation sulfur purifier volume are little, and sulfur purifier is the self-excitation sulfur purifier, does not need to add in addition power;

3, because sulfur purifier respectively from top to bottom, from bottom to top stirs chemical agent, make it sufficient reacting, to sulphur and toxic and harmful purifying rate height;

4, the scope of application is big, suitable all size boiler, kiln;

5, the air-introduced machine air outlet slit has only 2 meters high, has saved 28 meters high chimneys;

6, long service life;

7, have water saving, economize on electricity, save land, energy-conservation characteristics;
