Abstract
The utility model discloses a self-cleaning phenazine tower. The self-cleaning phenazine tower comprises a distilling still, a tower body and a cooler which are sequentially and serially connected from bottom to top, wherein the tower body is formed by serially connecting not less than two tower sections; a flushing transition section is connected between the tower sections; and the flushing transition section is connected with a flushing pipeline. The distilling still of the self-cleaning phenazine tower is connected with a delivery pump which is connected with a receiving tank, a recovery tower and the flushing pipeline respectively. When the self-cleaning phenazine tower works, a residual liquid obtained after separation by using the phenazine tower is transferred to the recovery tower for recycling by using the delivery pump. The flushing pipeline, the delivery pump and a pipeline of the recovery tower are serially connected with a valve in order to realize the switching of operating and cleaning states of the self-cleaning phenazine tower; and by a valve switch, the cleaning of a flushing liquor on the blocked tower sections at the bottom of the tower body after the flushing liquor is fed into the tower body by using the delivery pump is realized. The cleaning function of the phenazine tower during blocking can be realized by arranging a section of transition section on the middle part of the tower body and connecting the transition section and the flushing pipeline; the phenazine tower has a simple structure and is convenient to maintain; the traditional process of disassembling the tower body to clean respectively when the phenazine tower is blocked is eliminated; and the structure of the conventional phenazine tower is improved.
Description
Technical field
The utility model belongs to Chemical Manufacture instrument and equipment technical field, is the azophenlyene tower structure with self-cleaning function specifically.
Background technology
The azophenlyene tower is a kind of equipment that often uses in the commercial production; Usually be applied in the research of type of production users such as oil, chemical industry, rubber, agricultural chemicals, dyestuff, medicine, food and various scientific experiment projects, be used for accomplishing technical process such as hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, hydrocarbonylation, polymerization, condensation, heating are mixed, isothermal reaction.During use, carry out abundant reacted raffinate by its further separation in the multiple industrial chemicals input tower body, to realize reusable purpose.
But existing azophenlyene tower structure in use for some time; Because the obstruction that tower body is inner usually causes the mass transport difficulty, need stop this moment producing; Again clean after tower body being decomposed; The ability operate as normal causes the interruption of production process thus, can not realize continuous, aim of stable operation fully.
Through discovering, the reason that the azophenlyene tower takes place to stop up not is the top section that occurs in tower body, and normally occurs in the tower body lower part; Therefore; In conjunction with stopping up the actual conditions that take place, the utility model has improved the structure of original azophenlyene tower, to realize cleaning automatically the function of obstruction place.
Summary of the invention
The purpose of the utility model is in order to solve the defective that above-mentioned azophenlyene tower can not continuous operation, to improve the structure of existing azophenlyene tower, making it can be operated under the continuous state; And the overall structure compact, cost is low, takes up an area of few; Material reaction is even, and yield is high, and output is big and product quality is high.
The technical scheme that realizes above-mentioned purpose the utility model does; A kind of self-cleaning azophenlyene tower; Comprise the distillation still, tower body and the cooler that are serially connected in successively from bottom to up together; Tower body forms by being no less than two tower joint serial connections, and between the tower joint, connects the flushing transition segment, connects flushing pipe on the flushing transition segment.
The distillation still of said self-cleaning azophenlyene tower connects delivery pump, also connects the other end of receiving slit, recovery tower and flushing pipe on the delivery pump respectively.During operate as normal, the raffinate that separates through the azophenlyene tower is sent to recovery tower to recycle through delivery pump.
For realizing work of said self-cleaning azophenlyene tower and the switching of cleaning two states, be connected with valve on the pipeline of flushing pipe and delivery pump and recovery tower, can realize that through valve switch flushing liquor sends into tower body through delivery pump the cleaning that tower saves is stopped up in the bottom.
In commercial production, the tower body of said self-cleaning azophenlyene tower is connected and composed by 4 Jie Tajie, and the flushing transition segment is between the second and the 3rd tower joint.
Utilize the technical scheme of the utility model; Through increasing by one section transition segment and connect flushing pipe at the tower body middle part; Can realize the cleaning function when the azophenlyene tower takes place to stop up, simple, easy to maintenance on the structure; Reduced when traditional azophenlyene tower stops up and to have dismantled the operation that tower body cleans respectively, improved the structure of existing azophenlyene tower.
Description of drawings
Fig. 1 is the said self-cleaning azophenlyene of a utility model tower structure sketch map;
Among the figure, 1, cooler; 2, tower body; 2-1, tower joint; 3, recovery tower; 4, transition segment; 5, receiving slit; 6, delivery pump; 7, distillation still.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is specifically described; Like Fig. 1 is the said self-cleaning azophenlyene of the utility model tower structure sketch map; As shown in the figure, the composition of self-cleaning azophenlyene tower is distillation still 7, tower body 2 and cooler 1 from bottom to up successively, and tower body is made up of 4 joint tower joint 2-1 in the present embodiment; A flushing of serial connection transition segment 4 connects flushing pipe on the transition segment between the 2nd and the 3rd Jie Tajie.The distillation still outlet of the bottom that tower body connected is connected with delivery pump, also connects the end of receiving slit 5 and recovery tower 3 and flushing pipe on the delivery pump respectively.On the pipeline of flushing pipe and delivery pump and recovery tower, be connected with valve 4.
During the utility model work, when azophenlyene tower operate as normal need not cleaned, separation was deposited into distillation still with raffinate to material through the azophenlyene tower, and delivery pump is sent to recovery tower with the raffinate in the distillation still and recycles; When taking place to stop up; The valve open of pipe blow-through; Transfer pump is conveyed into two towers joint of azophenlyene tower bottom with the cleaning fluid in the receiving slit through pipe blow-through and transition segment, and cleaning fluid is back in the distillation still equally with the work raffinate and collects, and recycles in that mixed liquor is recycled to recovery tower.
Technique scheme has only embodied the optimal technical scheme of the utility model technical scheme; The technical staff in present technique field to some part wherein some changes that possibly make all embodied the principle of the utility model, belong within the protection domain of the utility model.
