Description

Waste gas direct cooling device

Technical Field

The utility model relates to a straight cold ware of waste gas.

Background

The cooling system used by the existing ethylene oxide waste gas water treatment equipment cools the ethylene oxide gas by cooling the absorption solvent firstly and then utilizing the full contact of the absorption solvent and the waste gas, and the loss of cold energy in the operation of the equipment is relatively large in the indirect cooling mode, so that the whole refrigeration effect is influenced, and the energy consumption is increased. In addition, the indirect cooling mode prolongs the time required by refrigeration, thereby reducing the effective reaction time of the ethylene oxide gas in the equipment and reducing the purification efficiency of the ethylene oxide wastewater gas treatment equipment.

Further: the fin coil pipe's coil pipe circulation dish establish and form a plurality of groups of parallel tube face from beginning to end, a plurality of body equidistance intervals of tube face set up, in the adjacent two sets of tube faces in the front and back, the body position of the preceding group tube face is opposite with the interval position axial of the body of back group tube face.

Further: the waste gas channel is provided with a plurality of baffle plates, and adjacent baffle plates are oppositely fixed on the side wall surface of the waste gas channel.

Further: and a plurality of groups of fin coil pipes are arranged in the waste gas channel, and the inlet pipes and the outlet pipes of the plurality of groups of fin coil pipes are sequentially connected end to end.

Further: the fin coil pipe is fixed on the mounting frame, the side of the direct cooling box body is provided with a fixing groove position for fixing the mounting frame, and the mounting frame is fixed on the mounting groove position through a bolt piece.

Further: the direct cooling box body and the fin coil pipe are made of acid-resistant and corrosion-resistant materials.

Further: the exhaust gas direct cooler according to claim 1, characterized in that: the acid-resistant and corrosion-resistant material 316L stainless steel.

Compared with the prior art, the utility model, have following advantage and effect: structural design is reasonable, simple structure, and the transformation is with low costs, and simple to operate conveniently reduces ethylene oxide exhaust gas temperature, makes its part convert liquid and absorption solvent mixture into, and the remainder gets into exhaust-gas treatment equipment and handles, improves the treatment effeciency of ethylene oxide waste gas, improves the effect that exhaust-gas treatment equipment handled, can carry out recovery processing to ethylene oxide simultaneously.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Referring to fig. 1-3, the waste gas direct cooler of the present embodiment includes a direct cooling box 1 and a fin coil 2, the fin coil 2 is disposed in a waste gas channel 14 of the direct cooling box 1, an air inlet pipe 11 and an air outlet pipe 12 are respectively disposed at two ends of the direct cooling box 1, and a liquid outlet 13 is disposed at the bottom of the waste gas channel 14.

In the embodiment, the EO waste gas direct cooler is added before the ethylene oxide waste gas enters the waste gas treatment equipment, the required treatment gas is directly cooled, the temperature of the ethylene oxide gas entering the equipment is reduced to be lower than the boiling point of the ethylene oxide gas, the ethylene oxide gas flows into the absorption solvent in a liquid state to be mixed, part of gaseous ethylene oxide is continuously introduced into the treatment equipment, the cooling time is greatly reduced, and the purification effect of the ethylene oxide waste gas treatment equipment is improved.

The fin coil 2's coil pipe circulation dish establish and form a plurality of groups of parallel tube face 21 from beginning to end, a plurality of bodys 22 equidistance interval of tube face 21 set up, in two sets of tube faces 21 adjacent from beginning to end, the body 22 position of the preceding group tube face 21 is opposite with the interval clearance position axial of the body 22 of the back group tube face 21, exhaust gas passageway 14 be provided with a plurality of baffling boards 3, adjacent baffling board 3 is the subtend and fixes on exhaust gas passageway 14's side wall face, improves the buffering of exhaust gas in exhaust gas passageway, improves heat transfer effect.

Exhaust passage 14 in be provided with multiunit fin coil pipe 2, multiunit fin coil pipe 2 go into pipe 23 and exit tube 24 end to end connection in proper order, fin coil pipe 2 fix on the mounting bracket, the side of direct-cooling box 1 be provided with the fixed slot position that is used for fixed mounting bracket, the mounting bracket pass through the bolt spare and fix on the installation slot position, in-service use can choose for use fin coil pipe 2's quantity according to the waste gas volume, simple to operate simultaneously.

The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
