Abstract

The utility model relates to a damping averager. The damping averager is composed of a communicating device which is composed of barrel bodies (1), (2) and a communicating pipe (4), an air distribution pipe (10) communicated with the two barrel bodies, an air discharge pipe (5) which is arranged in the barrel body (1) and communicated with the atmospheric air and an air inlet pipe (6) installed on the barrel body (2); the upper part of the communicating device is also provide with a drug feeding device (7), and the lower part is provided with a vent pipe (8). The averager has high absorptivity for sour gases or the ammonia gas, and the utility model stops generating the gas leakage of the hydrochloric acid or the ammonia in the process of loading, unloading and storage. Besides, the utility model has the advantages of low operation cost and small maintenance work load.

Description

Damping averager

The utility model relates to a kind of device that prevents acid gas or ammonia systemic contamination environment, relates to specifically a kind ofly can to prevent to load and unload in the loading and unloading, storage, use of acid, ammonia, the excessive and damping type neutralizer of contaminated environment of the acid gas in the storage, operative installations or ammonia.

Hydrochloric acid or ammoniacal liquor all have very strong volatile, in loading and unloading, storage, use, have a large amount of acid gas or ammonia excessive, contaminated environment, its harm is very big, must be handled, and usually adopts following three kinds of methods to handle more:

A, the sealing of use liquid paraffin are though the sealing effectiveness of the method is pretty good, often because of paraffin can not thoroughly separate with acid, so should not use under many circumstances;

B, employing acid mist resorber are about to acid mist and introduce washing in the resorber, and this kind method water consumption is big, and effect is not good enough;

C, utilize baton round to cover sealing, this method also only can cover 89% of payload space, so its result of use is not very good yet if under desirable covering state.

The purpose of this utility model provide with regard to being to overcome above-mentioned weak point of the prior art a kind of rational in infrastructure, absorb to imitate the high damping type neutralizer that pollutes can stopped substantially.

The purpose of this utility model can adopt following measure to realize:

Damping type neutralizer of the present utility model by about two cylindrical shells and the permeator formed communicating pipe, be used to be communicated with the gas distribution pipe of two cylindrical shells, and be arranged on the left side in the cylindrical shell the freeing pipe that communicates with atmosphere and the air inlet pipe that is installed on the cylindrical shell of right side form; Chemicals dosing plant is equipped with on the top of permeator, and the bottom is provided with blow-down pipe.

One end of the gas distribution pipe on this neutralizer is connected with the top of right side cylindrical shell, and the other end then is arranged in the inner chamber of left side cylindrical shell, and the bottom of this end is equipped with the breathing pipe that is connected with the gas distribution pipe, offers through hole on the breathing pipe.On cylindrical shell, also be provided with the liquidometer that shows liquid level.Chemicals dosing plant and blow-down pipe can be arranged on any one cylindrical shell in two cylindrical shells.

For making gas distributed uniform in neutralizer, improve neutralization, above the breathing pipe that is positioned at the left side cylinder lumen, a damping screen is housed.

The utility model compared with prior art not only has acid gas or ammonia absorptivity height, can stop hydrochloric acid or ammoniacal liquor substantially and in loading and unloading, storage, use, produce acid gas or the excessive phenomenon of ammonia, and have the advantage that over-the-road expense is low, maintenance workload is little.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a kind of embodiment of breathing pipe among Fig. 1.

Fig. 3 is second kind of embodiment of breathing pipe among Fig. 1.

The utility model is done with detailed description below with reference to embodiment (accompanying drawing):

Damping type neutralizer of the present utility model by about two cylindrical shells (1) (2) and the permeator formed communicating pipe (4), the gas distribution pipe (10) that is communicated with two cylindrical shells (1) (2), and be arranged on its terminal freeing pipe (5) that communicates with atmosphere in the cylindrical shell (1) and be installed in air inlet pipe (6) composition on the cylindrical shell (2).In permeator, be filled with neutralizer.Below the liquid level of cylindrical shell (1) inner chamber, a damping screen (11) is equipped with in the top of breathing pipe (3).

Chemicals dosing plant (7) also is equipped with on the top of cylindrical shell (1), and the bottom of cylindrical shell (1) is provided with blow-down pipe (8); Cylindrical shell (1) is provided with the liquidometer (9) that is used to show liquid level; One end of gas distribution pipe (10) is connected with the top of cylindrical shell (2), and the other end is arranged in the inner chamber of cylindrical shell (1), and the bottom of this end is equipped with the breathing pipe (3) that is connected with gas distribution pipe (10), and breathing pipe offers through hole on (3).

As shown in Figure 2, breathing pipe (3) can be the cruciform shape structure; But also as shown in Figure 3, the outer ring is a cirque structure.

Damping type neutralizer of the present utility model combines by the air inlet-outlet pipe on the holding vessel that is positioned at air inlet pipe (6) and acid on the cylindrical shell (2) or ammonia.

Principle of work of the present utility model is as follows:

Under normal condition (static state), this damping type neutralizer is exactly a perfect U type liquid closing appliance, makes acid gas and atmospheric isolation in the jar; When acid storage tank fills acid, because clearance envelope dwindles gradually in jar, cause the rising of mixture pressure in the tank body, under the effect of gaseous tension, liquid level in the cylindrical shell of damping type neutralizer (2) descends, liquid level in the cylindrical shell (1) then correspondingly rises, when liquid level difference reaches certain certain value (150--200mm), miscellaneous gas is through the breathing pipe (3) of gas distribution pipe (10) bottom, pass neutralizer barrier layer (promptly and purification process), purified gas enters atmosphere (purpose that damping screen (11) is set is for making gas distributed uniform in neutralizer, improving neutralization) through freeing pipe (5); When the outside acid discharge of acid storage tank, the change gradually of clearance envelope is big in jar, make the decline of mixture pressure in the tank body, under the effect of gaseous tension, liquid level in the cylindrical shell of damping type neutralizer (2) rises, liquid level in the cylindrical shell (1) then correspondingly descends, when liquid level difference reaches certain certain value, be that liquid level is when being lower than the breathing pipe (3) of gas distribution pipe (10) bottom, this moment, air entered cylindrical shell (2) by the breathing pipe (3) of gas distribution pipe (10) bottom through gas distribution pipe (10), then entered acid storage tank.
