The combined device of the in-tower grid plate and the lateral line discharging hole not only can collect liquid, ensures gas to flow and the liquid to be drained in the lateral line, but also has the function of supporting the stuffing; moreover, the utility model has the advantages that the combined device has a simple structure, is convenient to sample, has uniform backflow distribution without damaging gas and liquid balance in the tower and is convenient to dismantle and maintain, etc.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, is specifically related to screen and the device that the side line discharging opening combines in a kind of rectifying column, is a kind of being applied in the separation process of vapour-liquid mixture, the device that midbarrel discharging and filler support.
Background technology
Rectifying is operating unit important in the industrial processes, is the important means that industry products such as chemical industry, medicine are purified and reclaimed.The kind of rectifier unit is a lot, and the internal structure of tower is varied, and for multicomponent side line discharging filling extract rectification device, the filler of tower supports and the design of side line discharging opening is even more important.
Employed various side line discharging openings and support screen all are relatively independent at present, adopt relatively independent side line discharging opening and support the effect that screen can play discharging and support, but because side line discharging opening and screen all have certain height, use the height that can increase tower respectively, increased the investment of equipment simultaneously.If can and support screen two parts with the side line discharging opening combines effectively, not only can reduce the height of tower, simultaneously can save the device fabrication material, but in existing disclosed documents and materials, side line discharging opening and propping bar be hardened to close as yet do not appear in the newspapers.
Summary of the invention
The purpose of this utility model provides the device of interior support of a kind of novel tower and the combination of side line discharging opening, and this device design is gone up side line discharging opening and support screen two parts are combined effectively, and simple in structure, easy to operate, feed back is evenly distributed.
The device of support and the combination of side line discharging opening is a kind of being adapted in the separation process of vapour-liquid mixture in the tower of the present utility model, the device that midbarrel discharging and filler support.The design feature of support and side line discharging opening coupling apparatus is in this novel tower: be provided with feeder in the device, the feeder bottom is connected with the side line discharge nozzle, even distribution wireway and overflow pipe in the groove, and the wireway top connects screen, and the upper end is convinced gas port by patient analysis.
The technical solution adopted in the utility model is as follows:
Screen and side line discharging opening coupling apparatus in a kind of tower, comprise feeder, wireway, overflow pipe and the side line discharge nozzle established in the device, wireway and overflow pipe are evenly distributed on the bottom of feeder, feeder is connected with discharge nozzle, it is characterized in that: described device also comprises screen, the wireway top directly is connected with screen, and the wireway upper end has uniform air guide port.
Described wireway is evenly distributed on the bottom of feeder, and length is a bit larger tham overflow pipe, and the length of wireway is 30 ~ 33mm usually, and diameter is φ 6, can amplify in proportion with tower diameter as required.The wireway top directly is connected with screen, and air guide port, the height of a little higher than overflow pipe of height of air guide port are evenly offered in the wireway upper end.By air guide port, following gas flows into the screen top smoothly.
Described overflow pipe is evenly distributed on the bottom of feeder, and length is slightly smaller than wireway, and the length of overflow pipe is 20 ~ 25mm usually, and diameter is φ 4, is slightly smaller than the diameter of wireway, also can amplify in proportion with tower diameter as required.Described overflow pipe lower end is provided with contraction mouth, and inserting down, the length of tower joint is 3 ~ 5mm.When liquid level was higher than overflow pipe in the feeder, tower joint below liquid flows into by overflow pipe was guaranteed the highly stable of liquid level in the feeder, evenly distributes simultaneously.
Feeder is connected with discharge nozzle, and partially liq is taken out, and all the other liquid reflux by overflow pipe.
Described coupling apparatus can be connected with the tower joint by flange plate.
" screen and side line discharging opening coupling apparatus in the tower " of the present invention not only can collect liquid, guarantees that gas flows and the liquid sidedraw discharging, plays the effect of supporting filler simultaneously.When the feeder liquid level was higher than overflow pipe in the device, tower saved below liquid flowed into by overflow pipe, and played the effect of distributor.
Beneficial effect: the device that screen combines with the side line discharging opening in the tower of the present utility model has simple in structure, convenient, the advantages such as being evenly distributed, not destroying the interior VLE of tower that refluxes of taking a sample, and be embodied in: 1. sampling does not influence the interior VLE of tower; 2. screen directly is connected with the wireway top, makes simple; 3. gathering-device is connected with the tower flange plate, is convenient to dismounting and maintenance; 4. refluxing is evenly distributed, and plays the effect of redistribution.
