Abstract
The utility model discloses a device for steam cleaning of recovery-section deposits in a distillation tower, which comprises two main steam pipes and a plurality of branch steam pipes, wherein the two main steam pips are symmetrical relative to the distillation tower, the branch steam pipes are respectively arranged on the two main steam pipes and connected to a recovery section of the distillation tower, a blowing nozzle of each branch steam pipe is arranged above a tower tray in the distillation tower, and the branch steam pipes are respectively provided with a steam blow-down valves. When the tower tray is blocked, the steam blow-down valves can be opened for cleaning the tower tray without influences to the work of the distillation tower; and with respect to the improvement, the device for steam cleaning of the recovery-section deposits in the distillation tower further comprises pressure detection devices respectively arranged on the bottom and the top of the recovery section of the distillation tower, and the main steam pipes are provided with flowmeters. Pressure difference inside the recovery section of the distillation tower can be checked through a pressure detection point so as to judge the blockage condition of the tower tray and further control the blowing amount of steam through the flowmeters, and thus, the purposes of blowing and not destroying the gas-phase balance in the distillation tower are achieved.
Description
Technical field
The utility model relates to a kind of steam cleaning plant, especially designs a kind of destilling tower exhausting section deposit steam cleaning plant.
Background technology
Destilling tower is one of capital equipment of chemical enterprise Distallation systm, during long-term operation, produce the higher boiling deposit when destilling tower exhausting section tower tray can be piled up distillation, these sediment piles are at tower tray and position, crack, the end, can result in blockage, make the material can't be dirty, form the stifled phenomenon of tower, tower occurs when stifled, destilling tower must be out of service, deposit in the tower need wash with water under high pressure and medicament, has so just reduced the working time of destilling tower, has reduced operating efficiency.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of destilling tower exhausting section deposit steam cleaning plant is provided, and it can clear up the deposit that is deposited in tower tray and position, crack, the end timely, and does not influence the operate as normal of destilling tower.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of destilling tower exhausting section deposit steam cleaning plant, comprise with respect to two main steam pipes of destilling tower symmetry and be located at some branch steam pipes on two main steam pipes respectively, steam pipe was connected on the destilling tower exhausting section in described minute, the tower tray top of the destilling tower that the blow gun of described minute steam pipe is positioned at is respectively equipped with the steam blowing valve on the described minute steam pipe.
As a kind of improvement, described destilling tower exhausting section deposit steam cleaning plant also comprises the pressure-detecting device that is located at destilling tower exhausting section bottom and top respectively, and described main steam pipe is provided with flowmeter.
As a kind of preferred version, the lowest part of described main steam pipe is provided with draining valve.
Owing to adopted technique scheme, the tower tray top of the destilling tower that the blow gun of branch steam pipe is positioned at is when sediment pile is on tower tray, open the steam blowing valve, released vapour purges cleaning, does not need destilling tower to quit work, and has improved operating efficiency.
Again because destilling tower exhausting section deposit steam cleaning plant also comprises the pressure-detecting device that is located at destilling tower exhausting section bottom and top respectively, described main steam pipe is provided with flowmeter, can can understand pressure differential in the destilling tower exhausting section by pressure-detecting device, thereby judge the stopping state of tower tray, and then can control the amount of steam blowing by flowmeter, both reached the purging purpose, again can the interior gas-liquid equilibrium of destructive distillation tower.
Because the lowest part of main steam pipe is provided with draining valve, the condensed water in the pipe that can let off steam before purging cleaning is in order to avoid influence the use of whole device again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure, 1, main steam pipe; 11, divide steam pipe; 12, the steam blowing valve; 13, draining valve; 14, flowmeter; 2, the gaseous pressure test point; 3, barometer.
The specific embodiment
As shown in the figure, destilling tower exhausting section deposit steam cleaning plant, comprise with respect to destilling tower symmetry two main steam pipes 1 and be located at some branch steam pipes 11 on two main steam pipes 1 respectively, steam pipe 11 was connected on the destilling tower exhausting section in described minute, the tower tray top of the destilling tower that the blow gun of described minute steam pipe 11 is positioned at is respectively equipped with steam blowing valve 12 on the described minute steam pipe 11.Described destilling tower exhausting section deposit steam cleaning plant also comprises the pressure-detecting device that is located at destilling tower exhausting section bottom and top respectively, described pressure-detecting device comprises the barometer 3 that is located on the gaseous pressure test point 2, and described main steam pipe 1 is provided with flowmeter 14.The lowest part of described main steam pipe 1 is provided with draining valve 13.
When the tower tray of destilling tower need clean, at first observe the barometer 3 on the gaseous pressure test point 2, numerical computations by barometer 3 goes out, pressure differential at the bottom of cat head and the tower, thus infer the stopping state of tower tray, the quantity of steam that needs when therefore determining cleaning, put before the steam, at first to open draining valve 13,, close draining valve 13 the row of the condensed water in pipeline light; The steam blowing valve of opening then on the branch steam pipe 11 12 cleans processing, clean out steam off blow down valve 12, adopt this structure, can under the situation of the work that does not stop destilling tower, clean processing, and can control the steam blowing amount according to stopping state, thereby neither cause the gas-liquid equilibrium of waste in also can the destructive distillation tower.
