Abstract
The utility model provides a slight negative pressure automatic control device which mainly comprises a tail gas absorption tower, a vacuum pump, a circulating absorbent liquid tank, a buffer tank, a circulating pump, a condenser, a closed liquid storage tank, an opened liquid storage tank, an adjustable support and the like, wherein a pipeline is arranged at the lower part of the absorption tower and connected with a slight negative pressure reaction system, the upper opening of the closed liquid storage tank is communicated with the bottom of the absorption tower, a pipe is arranged at the lower opening of the closed liquid storage tank, and the lower end of the pipe extends to the bottom of the opened liquid storage tank. During the chemical reaction requiring the slight negative pressure condition, the slight negative pressure automatic control device can automatically control the whole process without needing the monitoring and regulation from time to time.
Description
Technical field
The utility model relates to the control device in a kind of chemical reaction process, especially a kind of automaton that is used for the little negative pressure of reaction system needs.
Background technology
Have a lot of chemical reactions to carry out under the condition of little negative pressure, need the situation of the little negative pressure of strict control in course of reaction, generally all adopt in surge tank emptying at present and control, because the negative pressure instability needs monitoring constantly to regulate, operation is trouble very.
The utility model content
The purpose of this utility model overcomes deficiency of the prior art exactly, and a kind of little negative pressure automaton that provides.
The technical solution of the utility model is achieved in that
A kind of little negative pressure automaton is provided, form by tail gas absorber, vacuum pump, circulating absorption solution pond, surge tank, ebullator, condenser, enclosed liquid storage tank, uncovered wet tank and adjustable support etc., the bottom on described absorption tower is provided with pipeline, link to each other with little negative reaction system, the bottom on the suitable for reading and absorption tower of enclosed liquid storage tank communicates, end opening is provided with a pipe, and the lower end of pipe is deep into the bottom of uncovered wet tank.
Advantage of the present utility model is: when carrying out the condition of the little negative pressure of chemical reaction needs, monitoring is regulated when not taking, and whole process can be controlled automatically and finish.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model:
Referring to accompanying drawing, a kind of little negative pressure automaton is provided, form by tail gas absorber 1, vacuum pump 2, circulating absorption solution pond 3, surge tank 4, ebullator 5, condenser 6, enclosed liquid storage tank 7, uncovered wet tank 8 and adjustable support 9 etc., the bottom on described absorption tower 1 is provided with pipeline 10, link to each other with little negative reaction system, the bottom on the suitable for reading and absorption tower 1 of enclosed liquid storage tank 7 communicates, and end opening is provided with a pipe 11, and the lower end of pipe 11 is deep into the bottom of uncovered wet tank 8.
See also accompanying drawing, the setting height(from bottom) on absorption tower 1 is by the needed negative pressure decision of reactive system; The height of pipe 11 is also by the needed negative pressure value decision of reactive system.
Use principle of the present utility model and process are as follows: after installing according to synoptic diagram, at first in uncovered wet tank 8, pour a spot of circulation fluid into, its circulation fluid quantity of pouring into can not surpass 2/3 of enclosed liquid storage tank 7, can not be less than the cavity volume of pipe 11.Open condenser 6 recirculated waters then, start ebullator 5, vacuum pump 2, along with negative pressure in the absorption tower 1 constantly increases, liquid in the uncovered wet tank 8 can rise along pipe 11 always, after negative pressure reaches setting value, the liquid level of pipe 11 should maintain a constant position, if the reactive system negative pressure has surpassed setting, liquid in the uncovered wet tank 8 will be inhaled in the enclosed liquid storage tank 7, after blotting, air will enter into enclosed liquid storage tank 7 with the form of bubbling by pipe 11, thereby enter into absorption tower 1, negative pressure value will lower.In case negative pressure value is low excessively, the liquid in the airtight storage tank will flow back in the uncovered wet tank 8 by pipe 11, blocks entering of air, and vacuum tightness is raise once again, reaches the numerical value of regulation.
This device can be applied in the system of the little negative reaction of a lot of needs, and also can be applied to needs on all kinds of containers of little negative pressure protection.
