Abstract
The utility model relates to an ammonia supply system formed by a plurality of ammonia decomposition furnaces. A liquid ammonia bottle is communicated with annealing furnaces through an ammonia decomposition generator and a check valve and is communicated with an ammonia supply main pipe, ammonia inlets of a plurality of ammonia generators are respectively connected in parallel with the ammonia supply main pipe, the ammonia outlet of each ammonia generator is communicated with an ammonia supply branch pipe, and the annealing furnaces are communicated with the ammonia supply branch pipe. The utility model has the advantages that due to the adoption of the coefficient of supplied ammonia of the parallel connection pipelines, the ammonia supply system not only ensures the ammonia supply pressure and the ammonia supply amount required for the annealing furnaces, but also improves the operating efficiency of the ammonia supply pipeline, and most importantly, the security of ammonia supply is enhanced; and the structural design is novel, unique, simple and practical and the manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of airing system that is made of many ammonia destruction furnaces, can either guarantee effectively that liquefied ammonia decomposes safety, can give the ammonia destruction furnace air feed again reliable and securely, belongs to the ammonia destruction furnace steam line and makes the field.
Background technology
Existing ammonia destruction furnace steam line on the market to producer, arrives annealing furnace from the liquefied ammonia bottle again, all is that independent tubes connects, and when using many ammonia destruction furnaces, not only pipeline is intricate, also is easy to generate gas leakage.The more important thing is: because ammonia is a toxic gas, the nitrogen and hydrogen mixture after the decomposition has the possibility of blast.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design and a kind ofly can either guarantee to simplify the airing system that conduit arrangements is made of many ammonia destruction furnaces again to many annealing furnace air feed.
Design: to achieve these goals.1, several liquefied ammonia bottles are communicated with the air-supply duct house steward, the inlet mouth of many ammonia generators is in parallel with air supply header respectively, the air outlet of each ammonia generator is communicated with gas manifold, and many designs that annealing furnace is communicated with gas manifold are one of technical characterictics of the present utility model.The purpose of doing like this is: can either guarantee many supply gas pressure and the air demands that annealing furnace is required, improve the working efficiency of steam line again, the more important thing is the security that has improved air feed.2, on the main pipe line between liquefied ammonia bottle and ammonia are grown up to be a useful person reducing valve being housed, is two of technical characterictic of the present utility model.The purpose of doing like this is: reducing valve can be regulated by pressure, controls whole steam line pressure and flow, makes whole steam line be in highly reliable safe condition, guarantees the works better of annealing furnace.3, pipeline adopts iron pipe as far as possible, uses plastics tubing less, is three of technical characterictic of the present utility model.The purpose of doing like this is: because cast iron pipe than plastic tube intensity height, is difficult for gas leakage, it is neat easily to arrange, and therefore can arrange neatly by pipeline, safe and reliable, in the work-ing life of improving pipeline effectively, increases economic efficiency.
Technical scheme: the airing system that constitutes by many ammonia destruction furnaces, the liquefied ammonia bottle decomposes producer by ammonia and stopping valve is communicated with annealing furnace, described liquefied ammonia bottle is communicated with the air-supply duct house steward, the inlet mouth of many ammonia generators is in parallel with air supply header respectively, the air outlet of each ammonia generator is communicated with gas manifold, and many annealing furnaces are communicated with gas manifold.
The utility model is compared with background technology, and the one, adopt parallel pipeline air feed coefficient, can either guarantee many supply gas pressure and the air demands that annealing furnace is required, improve the working efficiency of steam line again, the more important thing is the security that has improved air feed; The 2nd, structure design novelty, uniqueness, simple, practical, low cost of manufacture.
Description of drawings
Fig. 1 is the airing system structural representation that is made of many ammonia destruction furnaces.
Embodiment:
Embodiment 1: with reference to Fig. 1.The airing system that constitutes by many ammonia destruction furnaces, several liquefied ammonia bottle 1 parallel connections are communicated with annealing furnace 6 by ammonia decomposition producer 3, stopping valve 4, under meter 5, described several liquefied ammonia bottles 1 are communicated with the air-supply duct house steward, the inlet mouth of many ammonia generators 3 is in parallel with air supply header respectively, the air outlet of each ammonia generator 3 links to each other with air supply header, distribute to many annealing furnaces 6 by each arm again, described many are meant more than 3,4.
Embodiment 2: on the basis of embodiment 1, liquefied ammonia bottle 1 is communicated with air supply header by reducing valve 2, what air supply header adopted is iron pipe, be connected in series between each ammonia generator 3 and gas manifold before under meter 5 and stopping valve 4 and under meter 5 be serially connected in stopping valve 4, every annealing furnace 6 pipes are equipped with under meter 5-1, and under meter 5-1 inlet mouth is communicated with gas manifold.
For example: with reference to accompanying drawing 1.4 bottles of liquefied ammonia bottles 1 are parallel to house steward, cross reducing valve 2, the inlet mouth that feeds 4 ammonia generators 3 respectively is communicated with and is connected with liquefied ammonia bottle 1 by reducing valve 2 with air supply header is in parallel, the outlet of 4 ammonia generators 4 is connected with air supply header with under meter 5 by stopping valve 4 respectively, be communicated with arm, 10 under meter 5-1 inlet mouths and gas manifold be in parallel to be communicated with and 10 under meter 5-1 air outlets are communicated with 10 annealing furnaces 6 respectively again.Above-mentioned all parts productions all are prior art, so be not described herein at this.
What need understand is; though above-mentioned fact Example is to the utility model detailed text description of contrasting; but these text descriptions; it is simple description to the utility model mentality of designing; rather than to the restriction of mentality of designing of the present utility model; any combination, increase or modification that is no more than the utility model mentality of designing all falls in the protection domain of the present utility model.
