Abstract
The utility model relates to a negative pressure washing device for an oxygen analyzer used for a preprocessing system of the oxygen analyzer with the technology of du pont dry-process acrylic fibers. The utility model is provided with a liquid storing container on which a gas inlet, a gas outlet, a desalting water inlet and a desalting water overflowing outlet are arranged, and a communicating pipe which is communicated with the upper part of the liquid storing container is additionally arranged on the desalting water overflowing outlet of the liquid storing container. The utility model which is simple and reasonable is convenient for observation and operating adjustment, the stabilized control of liquid levels can be realized, detected gas obtains better washing effect, the normal and stable operation of the oxygen analyzer can be ensured, and therefore, safety in production and product quality can be ensured.
Description
The utility model relates to a kind of oxygen analyzer negative pressure scrubber, is used for Du Pont's dry acrylic fiber technology oxygen analyzer pretreatment system.
In Du Pont's dry acrylic fiber explained hereafter, oxygen analyzer is very important equipment, and the stability of its operation and reliability directly influence safety in production and product quality.Being used to detect the main cause that medium has the oxygen analyzer fluctuation of service of autohemagglutination gas, corrosive gas at present is to contain a large amount of autohemagglutinations, corrosive gas in the detected gas.This just required before detected gas enters oxygen analyzer sensing chamber, the autohemagglutination that must carry detected gas with desalted water, corrosive gas washes away, and existing scrubber design owes reasonable, negative pressure in the liquid storage container makes to have only when the liquid level of desalted water is higher than the spillway certain altitude, its inner desalted water could flow out, and it is too small or when closing when the desalted water flow that enters liquid storage container, liquid level not only can not keep, even can reduce to zero, cause its inner desalted water liquid level can not stablize control, cause clean result undesirable, the part autohemagglutination, corrosive gas enters the sensing chamber of oxygen analyzer, and sensing chamber is damaged; And when the desalted water liquid level in the liquid storage container is too high, be easy to cause sensing chamber's water inlet, influence the operate as normal of sensing chamber, even damage sensing chamber.
The purpose of this utility model is the oxygen analyzer negative pressure scrubber that provides a kind of clean result good to have guaranteed the normal stable operation of oxygen analyzer.
And convenient the observation and the adjustment operation.
Oxygen analyzer negative pressure scrubber described in the utility model, one liquid storage container is arranged, liquid storage container is provided with air intake opening, gas outlet, desalted water inlet and desalted water spillway, is provided with the communicating pipe that is communicated with liquid storage container top on the desalted water spillway of liquid storage container.
The setting of communicating pipe, making pressure in the liquid storage container be connected with desalted water spillway place and with spillway is that the interior pressure of delivery pipe is equal, has eliminated the adverse effect of negative pressure.Carried out under the condition of water seal at delivery pipe lower end floss hole, when in a single day the liquid level in the liquid storage container was higher than spillway, its inner desalted water will flow out; When liquid level is lower than spillway, just stop to flow, thereby realized the stable control of liquid level, make detected gas obtain clean result preferably, guaranteed the normal stable operation of oxygen analyzer.
Be provided with liquid level gauge outside liquid storage container, so that observe the liquid level in the liquid storage container, the convenient flow of adjusting desalted water is to obtain Optimal Control.As long as adjust flow of inlet water, make flow of inlet water less than maximum emission, the desalted water liquid level in the liquid storage container just can obtain stable control.
Below in conjunction with drawings and Examples the utility model is further described.
The cross section structure synoptic diagram of Fig. 1, the utility model one embodiment.
As shown in the figure, oxygen analyzer negative pressure scrubber described in the utility model, one liquid storage container 3 is arranged, liquid storage container 3 is provided with air intake opening 1, gas outlet 2, desalted water inlet 6 and desalted water spillway 5, be provided with the communicating pipe 4 that is communicated with liquid storage container 3 tops on the spillway 5 of liquid storage container 3, the lower end of the delivery pipe that is connected with spillway is that water seal is isolated.Liquid storage container 3 outsides are provided with liquid level gauge 7.
From this, the utility model improves simple, scientific and reasonable, and be convenient to observe and the operation adjustment, can realize the stable control of liquid level, make detected gas obtain clean result preferably, guarantee the normal stable operation of oxygen analyzer, thereby guaranteed safety in production and product quality that Du Pont's dry acrylic fiber is produced, obtained favorable economic benefit and social benefit.
