Abstract

The utility model discloses a smoke elimination and dust removal device. The utility model adopts the structure that a venturi tube is installed on one end head of a box body in a vertical direction, and the lower part of the box body is provided with a sedimentation tank, and the upper part of the box body is a gas washing chamber; a bell mouth of the venturi tube extends into the box body and is above the water surface of the sedimentation tank, and a swirling chamber which is inserted into a smoke inlet pipe in a tangential direction is installed on an upper bell mouth of the venturi tube; a traverse baffle is installed in the gas washing chamber, the traverse baffle enables smoke gas to turn upwards and downwards, and the traverse baffle can enter water in the sedimentation tank when the traverse baffle turns downwards; a draught fan pumps washed smoke gas into a chimney to discharge. As the device carries out washing and dust removal operation to exhaust gas with dust by many times, purification degree to smoke and the dust is high, and the utility model has the advantages of simple structure and convenient operation.

Description

A kind of device for eliminating smoke and dust

The utility model belongs to device for eliminating smoke and dust.

Be the protection environment, in the industrial processes or the flue dust of civilian discharging, how remove the wherein grit of being with at present with spray process; But for discharging fume amount the greater, single very difficult that the dust removing is clean with this method, and the also easily obstruction of the aperture of the used spray head of spray process, cleaning is inconvenience again, so the method dedusting is difficult to reach environmental emission standard.

The purpose of this utility model provide a kind of smoke medicining dust-removing effect good, use simple to operate, reliable device for eliminating smoke and dust.

For achieving the above object, the technical solution of the utility model is: the top, a termination that on bottom band sedimentation basin, top is the casing of gas washing chamber, vertically be installed with Venturi tube, its tubaeform end opening stretches in the case in the sedimentation basin above water, horn mouth top is equipped with circular swirling chamber on it, and smoke-intake pipe inserts indoor from the tangential direction of this chamber sidewall; In the other end crown of casing portion, the exhaust duct that communicates with it is installed, the other end of pipe is connected with the import of air-introduced machine; In the gas washing chamber between exhaust duct and Venturi tube, there have a plurality of deflection plates to erect respectively up and down to be staggered, keeps a determining deviation mutually and be fixed on perpendicular to fore-and-aft direction on the internal box wall of casing.

For making dust removing effects better,, also can be equipped with the water spray shower at the top of swirling chamber.

This device is owing to adopted swirling flow inertial dust collection, ash-laden gas after Venturi tube segregates into washing gas or spray adding water washing to the discharging flue dust, repeatedly do to impact cleaning dust again through the entry of deflection plate baffling, former dedusting time length to ash-laden gas, gas washing enter the discharging gas degree of purification height of smoke exhaust pipe often through air-introduced machine.This apparatus structure is simple, and is easy to manufacture.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a front view of the present utility model;

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

Fig. 3 is the B-B cutaway view of Fig. 1.

Among Fig. 1, the right-hand member crown portion that has the sedimentation basin 1 that is filled with water, casing 5 that top is gas washing chamber 4 in the bottom, setting is installed with Venturi tube 7, its tubaeform end opening stretches into more than the last plane of water in the interior sedimentation basin 1 of case, horn mouth top is equipped with the circular swirling chamber 10 that communicates with it on it, and the smoke-intake pipe 9 of the ash-laden gas of discharging inserts in the swirling chamber 10 (referring to Fig. 2) from the tangential direction of this chamber sidewall; For reaching better dust removing effects, also can be inserted with the shower 11 of band fountain head at the top of this chamber.In the left end crown of casing 5 one, the exhaust duct 15 that communicates with gas washing chamber 4 is installed, the other end of this pipe is connected on the air inlet of air-introduced machine 13, and the air outlet of air-introduced machine 13 runs on the smoke pipe 14, thereby with the flue gas after being purified emptying; Band water when preventing air-introduced machine 13 suction is equipped with the dewatering plate 16 (referring to Fig. 3) of the oblique baffle plate of band multi-disc in the bottom of exhaust duct 15.In the gas washing chamber between exhaust duct 15 and Venturi tube 7, have multi-disc (general 3～5) between the upper and lower every stagger, vertically disposed deflection plate 6, deflection plate is fixed on the front and back and last tank wall of casing 5 inwalls on it, its lower end in sedimentation basin 1 above water, following deflection plate is fixed on the front and back tank wall of casing 5, the space is left with last tank wall in its upper end, and the lower edge is inserted in the sedimentation basin 1 below the horizontal plane.Smooth and easy for blowdown, the bottom surface of sedimentation basin 1 can make that Xiang Yiduan tilts, and its lowest part leaves sewage draining exit 17.
