Description
Technical field
The utility model belongs to paper making equipment field, specifically discloses a kind of vacuum moisture trap for fourdrinier machine.
Background technology
Produce the paper machines such as boxboard, white board, cultural paper, especially adopt the fourdrinier machine of rebuilding, its wet end is generally provided with the dewatering elements such as breast roll, profiled sheeting, Wiper blade, wet suction box, suction flat box, suction couch roll.The air-water mixture that the wet equipment such as suction box, suction flat box produces needs to use vacuum moisture trap separation gas and water usually, one of its object ensures wet end plain boiled water amount, reduce wet end plain boiled water to run off, maintain white-water system normally to run, save production run cost, it two is avoid liquid to enter vavuum pump, causes vavuum pump to damage and avoids liquid to enter vavuum pump, cause vavuum pump to damage.
The principle of vacuum moisture trap is, steam moisture in a large number enters vacuum moisture trap, because gas is different with the density of liquid, separates gradually during flowing under certain effect power together, and gas and liquid are discharged from difference outlet respectively.
But the general output of modern paper machine is large, the speed of a motor vehicle is high, the vacuum moisture trap quantity that wet end uses is many, corollary system is complicated, wet end transmission side apparatus arrangement limited space, want each system equipment of reasonable coordination (pulse attenuator, drip tray, punching slurry back flow water pump, starching pipeline, dehumidifier pipeline, head box heating system, net exchanging device, vacuum moisture trap, Hydraulic Station, operation are walked on stage, reduction box and driving motor etc.) in the layout of wet end transmission side, difficulty is very large, easily affects paper machine and produces.
Current suction flat box has multi chamber vacuum suction box, mostly be double-chamber vacuum suction box, three Room suction flat boxs, and existing vacuum moisture trap is all single chamber, in order to coordinate multicell suction box, needs dislocation to put multiple vacuum moisture trap, installs inconvenience.And domestic and international most papermaking enterprise all takes circular vacuum moisture trap, take up an area more and treating capacity is limited.
Summary of the invention
For problems of the prior art, the purpose of this utility model is to provide a kind of vacuum moisture trap for fourdrinier machine.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of vacuum moisture trap for fourdrinier machine, it is characterized in that, comprise several arranged in parallel and casings be fixed together, the longitudinal section of each casing is the right-angled trapezium that hypotenuse is positioned at below, and the left surface height of each casing is less than right flank height; The left surface of each casing is equipped with air-water mixture import, and end face right-hand member is equipped with gas vent, and bottom surface right-hand member is equipped with liquid outlet; Each box house is all fixed with several tilting baffle plates.
Described vacuum moisture trap comprises 2 or 3 described casings, in order to double-chamber vacuum water aspirator or three Room water vacuums with the use of.
Described baffle plate is positioned at below gas vent, and after facilitating gas-water separation, gas is siphoned away by vavuum pump.
Described baffle plate and horizontal angle are 30-60 degree, and in this angular range, separating effect is better.
The quantity of described baffle plate is 1-3, and baffle plate number is too high does not have the effect continuing to improve separating effect, on the contrary can barrier gas circulation.
The area of described baffle plate is 1-3 times of air-water mixture import sectional area.
The spacing of adjacent two described baffle plates is 1-3 times of air-water mixture inlet diameter.
Adjacent two described casings share a face, can save material, reduce costs.
When using vacuum moisture trap of the present utility model, outlet corresponding with suction flat box for the air-water mixture import of each casing is connected, the air-water mixture that suction flat box sucks enters vacuum moisture trap, the passage gradually wide along cross section flows into, collide and reduce flow velocity on baffle plate, because proportion difference is separated, the gas of clean dried is aspirated by the gas vent at top and goes out, and liquid flows down along sidewall and flowed out by liquid outlet.
Compared with prior art, the utility model has the following advantages and useful technique effect: (1) can with existing multi chamber vacuum suction box with the use of, optimize wire-cloths transmission side to arrange, improve vacuum moisture trap gas-water separation efficiency, reduce vacuum system plain boiled water load, save production run cost.(2) channel setting that baffle plate and cross section are gradually wide can ensure higher gas-water separation efficiency, and its material, energy consumption cost all lower than other vacuum moisture traps, and easy to maintenance, long service life.(3) can be widely used in producing the long mesh paper making machines such as boxboard, white board, cultural paper.
