Description

Divide sour even steady acid divider of sour

Technical Field

The utility model relates to a sulphuric acid production facility, specifically speaking relate to a divide sour even steady acid ware of dividing.

Background

In a sulfuric acid production device, an acid separator is an important device in a drying or absorption tower, and particularly, the acid separator makes process gas flowing upwards from the bottom of a tower fully contact and be absorbed in concentrated sulfuric acid which is uniformly distributed in a packing layer by uniformly distributing the concentrated sulfuric acid which enters the drying or absorption tower. The performance of acid distributor not only influences the absorption rate of concentrated sulfuric acid to gas in the tower, more can directly influence the normal operating of whole system, and the sour quality of product is not up to standard, and lower absorption rate can lead to forming acid mist too much in the tower, causes the corruption of system's equipment of making acid serious, causes serious pollution even to the atmospheric environment.

At present, most of existing pipe-groove type acid distributors adopt a throttle orifice plate to adjust the flow entering each acid groove, but from the practical effect, the throttle orifice plate cannot accurately adjust the flow, so that the liquid level height in each groove is difficult to balance and is consistent, and moreover, the larger flow velocity generated at the throttle orifice plate can generate larger impact on the liquid level in the groove, so that the liquid level fluctuation is larger, and the acid amount flowing out from the overflow of each acid distributor is uneven. Therefore, the improvement of the structure and the performance of the acid separator are very necessary.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides an in the sulphuric acid apparatus for producing for sulphuric acid in drying or the absorption tower divides sour ware, it has designed double flute overflow structure dividing sour groove for the acid yield of outflow keeps even stable, and the while will divide sour groove miniaturization to make this product divide sour groove to use in miniature tower based on this characteristic.

The utility model provides a divide sour even steady acid divider of sour, includes into acid pipe, acid house steward, down acid pipe and divides sour branch pipe, its characterized in that: the acid distributing device is characterized in that an acid distributing groove is formed between the acid discharging pipe and the acid distributing branch pipe, the upper part of the acid distributing groove is a large acid distributing groove, the large acid distributing groove is communicated with the acid distributing branch pipe, the lower part of the acid distributing groove is a small acid distributing groove, the small acid distributing groove is communicated with the acid discharging pipe, an overflow plate is arranged between the large acid distributing groove and the small acid distributing groove, and a plurality of overflow holes are formed in the overflow plate.

As a further arrangement of the scheme, the bottom of the inlet end of the acid separating branch pipe is flush with the bottom surface of the large acid separating groove.

As a further arrangement of the scheme, each part of the acid distributor is made of glass fiber reinforced plastic or corrosion-resistant alloy materials.

As a further arrangement of the scheme, the small acid-separating groove is provided with a plurality of small acid-separating grooves which are communicated through pipelines.

In a further arrangement of the scheme, the diameter of the overflow holes arranged on the overflow plate is 2mm, and the arrangement density is 30-50 per square meter.

As a further arrangement of the scheme, the acid separating tank adopts an arrangement that the volume of the upper large acid separating tank is larger than that of the lower small acid separating tank, and the ratio of the acid separating tank to the lower small acid separating tank is 3: 1.

compared with the prior art, the utility model, following outstanding advantage has: the utility model discloses an overflow structural design of branch sour groove for divide sour intraductal unstable dynamic pressure of sour pipe to divide sour stable static pressure overflow to change into and divide sour inslot to divide sour, make the acidizing fluid that divides sour branch pipe to go out even, make the utility model discloses the product divides sour pipe shorter, and the cell body volume can be miniaturized, and the towelette is also applicable to the easy to assemble.

Detailed Description

The following detailed description of embodiments of the present invention is provided for the purpose of explanation, and is not to be construed as limiting the invention.

As shown in attached figures 1-2, the acid distributor for uniformly and stably distributing acid comprises an acid inlet pipe 1, an acid header pipe 2, a lower acid pipe 5 and an acid distributing branch pipe 4, and is characterized in that: the acid discharging pipe 5 and the acid distributing branch pipe 4 are provided with the acid distributing groove 3 therebetween, the upper part of the acid distributing groove 3 is a large acid distributing groove 31, the large acid distributing groove 31 is communicated with the acid distributing branch pipe 4, the lower part of the acid distributing groove 3 is a small acid distributing groove 32, the small acid distributing groove 32 is communicated with the acid discharging pipe 5, the overflow plate 33 is arranged between the large acid distributing groove 31 and the small acid distributing groove 32, and the overflow plate 33 is provided with a plurality of overflow holes 34.

Through the arrangement, after entering the acid distributor from the acid main pipe 2, the medium acid liquid enters the small acid distributing groove 32 through the acid discharging pipe 5, the liquid level of the acid liquid slowly rises in the acid distributing groove 3, and after the liquid level is over the bottom of the large acid distributing groove 31, the acid liquid is subjected to static pressure overflow through the overflow holes 34 arranged on the overflow plate 33 at the bottom of the large acid distributing groove 31, so that the acid liquid is stably and uniformly discharged through the acid distributing branch pipes 4.

As a further arrangement of the scheme, the bottom of the inlet end of the acid-separating branch pipe 4 is flush with the bottom surface of the major acid-separating groove 31.

Through the arrangement, acid liquor can be better guided and discharged.

As a further arrangement of the above scheme, the small acid separation tank 32 is provided with a plurality of small acid separation tanks which are communicated through pipelines.

Through the arrangement, the liquid levels of the acid liquor in the small acid separating grooves in the whole set of acid separating device are the same and uniform through the communication of the pipelines, and the problem that the acid is not uniformly separated due to the fact that the acid outlet from the acid separating branch pipe is poor due to overflow is avoided.

In a further arrangement of the scheme, the aperture of the overflow holes 34 arranged on the overflow plate 33 is 2mm, and the arrangement density is 30-50 per square meter.

As a further arrangement of the above scheme, the acid separating tank 3 adopts an arrangement that the volume of the upper large acid separating tank 31 is larger than that of the lower small acid separating tank 32, and the ratio of the volume to the volume is 3: 1.

the utility model discloses an overflow structural design of acid splitting groove for divide the intraductal unstable dynamic pressure of sour branch to divide sour and change into and divide sour inslot steady static pressure overflow branch acid, make the acidizing fluid of dividing sour branch pipe to go out even, make the utility model discloses the product divides sour pipe shorter, and the cell body volume can be miniaturized, is particularly useful for miniature turriform, and also can use at large-scale tower.
