Description
Technical field
The utility model belongs to Ammonia recovery technical field, particularly the novel ammonia recycling device of one.
Background technology
Ammonia is very easily water-soluble, can prepare ammoniacal liquor with water absorbing ammonia.Ammonia is water-soluble, volume-diminished, can increase the solubility of ammonia in water, thus obtain the ammoniacal liquor of high concentration by increasing pressure or reducing temperature.Namely the main task in ammonia job shop ammoniacal liquor post is unnecessary ammonia is generated ammoniacal liquor and processes the weak aqua ammonia sent here in synthesis workshop, plays the effect that balance ammonia is produced.
In actual production, the absorption tower in ammoniacal liquor post is ordinary-pressure absorption, is packing layer in the middle part of absorption tower, and top is spray equipment, and top blow-down pipe removes liquid layer built with filler.Ammoniacal liquor requires that certified products concentration is at 18%-20%, and it is between 13%-25% that weak aqua ammonia concentration is sent in synthesis workshop here, and carry not the melting property gas such as a small amount of methane secretly, pressure is 1.5MP.Synthesizing after the weak aqua ammonia sent here enters receiving slit beats to absorption tower bottom pressure relief with pump, enters ammonia vessel after most of ammoniacal liquor decompression bottom absorption tower, and another part ammoniacal liquor resolves volatilization for ammonia.The ammonia of resolving volatilization also enters 1# ammonia vessel after packing layer is absorbed into ammoniacal liquor by the clear water sprayed bottom absorption tower.The emptying after remove liquid except liquid layer of gas after absorption.Because weak aqua ammonia concentration instability is sent in synthesis here, pressure is higher, and excessive pressure reduction causes ammonia absorption pressure oscillation, and the ammonia that ammoniacal liquor resolves volatilization can not absorb completely in absorption tower, and part ammonia is overflowed from blow-down pipe, causes adverse effect to surrounding enviroment.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, the rate of recovery is high and the novel ammonia recycling device that cost is low.
For achieving the above object, the utility model is by the following technical solutions: novel ammonia recycling device, the ammonia pipe comprising water tank, ammoniacal liquor case, ammoniacal liquor collecting box, absorption tower and be communicated with absorption tower, water tank is communicated with absorption tower by water pipe, absorption tower is provided with water seal head, and ammonia pipe stretches in absorption tower through water seal head; Be provided with Ammonia recovery pipe in water seal head, Ammonia recovery pipe one end is communicated with absorption tower, and the other end to be located in water seal head and to bend downwards; Water pipe is with two arms, and an arm is connected with the shower nozzle be located in absorption tower, and another arm is connected with water seal head; Ammoniacal liquor collecting box is provided with absorption tower ammonia water pipe and end socket ammonia water pipe, and absorption tower ammonia water pipe is connected with bottom absorption tower, and end socket ammonia water pipe is connected with water seal head.
Further, ammoniacal liquor case passes through to be connected into ammonia water pipe with bottom absorption tower.
Further, in absorption tower, be provided with shower nozzle fabric swatch, described shower nozzle fabric swatch is evenly distributed with shower nozzle.
Further, water pipe is connected with water pump.
Compared with prior art, the beneficial effects of the utility model are as follows: absorption tower is provided with water seal head, and ammonia pipe stretches in absorption tower through water seal head, effectively enhances the sealing of device, prevent ammonia leakage from improving security; Be provided with Ammonia recovery pipe in water seal head, Ammonia recovery pipe one end is communicated with absorption tower, and the other end to be located in water seal head and to bend downwards, arranges bending place, can effectively increase ammonia and contact with water body, strengthens the absorptivity of ammonia, avoids the situation occurring ammonia leakage; Water pipe is with two arms, and an arm is connected with the shower nozzle be located in absorption tower, and another arm is connected with water seal head, adopts a water tank to supply water to water seal head and absorption tower simultaneously, reduces the quantity of parts, cost-saving; Ammoniacal liquor collecting box is provided with absorption tower ammonia water pipe and end socket ammonia water pipe, absorption tower ammonia water pipe is connected with bottom absorption tower, and end socket ammonia water pipe is connected with water seal head, and the ammoniacal liquor absorbed in absorption tower and water seal head enters ammoniacal liquor collecting box by pipeline, layout designs is reasonable, is conducive to the recovery of ammoniacal liquor; Ammoniacal liquor case passes through to be connected into ammonia water pipe with bottom absorption tower, arranges ammoniacal liquor case passing in ammonia forward direction absorption tower and passes into ammoniacal liquor, be conducive to the absorption of ammonia, increases Ammonia recovery rate; Be provided with shower nozzle fabric swatch in absorption tower, shower nozzle fabric swatch is evenly distributed with shower nozzle, shower nozzle is evenly arranged on shower nozzle fabric swatch, makes water body spray evenly, increases the absorptivity of ammonia.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
