Abstract
The utility model discloses an ammonia spray nozzle for flushing a pipe bridge of a coke oven. A spray nozzle outlet and a spray nozzle inlet are respectively arranged at both ends of an inner cavity in the middle of a spray nozzle shell. A spray nozzle flow deflector is arranged in an inner cavity of the spray nozzle inlet. The spray nozzle flow deflector is provided with a first deflector and a second deflector which are arranged in a relatively crossed mode. One half inner edge of the first deflector and one half inner edge of the adjacent second deflector are connected by a connection plate to form one whole body. The other half inner edge of the first deflector and the other half inner edge of the second deflector are respectively provided with guide slots. An outer edge of the first deflector and an outer edge of the second deflector are matched with the wall surface of the inner cavity of the spray nozzle inlet. After the ammonia spray nozzle is adopted, after ammonia flows through the ammonia spray nozzle, high-pressure high-flow conical surface ammonia flow can be formed and the inner wall of the pipe bridge can be uniformly sprayed by the conical surface ammonia flow, so that the purposes of saving energy and protecting the environment are fulfilled.
Description
Technical field
The utility model relates to the nozzle in the ammoniacal liquor flusher, refers to a kind of coke oven pipe bridge flushing ammoniacal liquor nozzle particularly.
Background technology
As everyone knows, the raw gas that is produced in the production process of coke oven is during through cross under, and the impurity of carrying secretly in the raw gas partly can if it is not washed for a long time, bring hidden danger can for maintenance of the equipment and safety in production attached on the bridge tube inwall.At present, at the problems referred to above, the patent No. is to have introduced " coke oven bridge tube with high and low pressure ammoniacal liquor nozzle " in the Chinese utility model patent specification sheets of ZL200820011242.0, it provides a kind of coke oven bridge tube high and low pressure ammoniacal liquor nozzle, be to be provided with jet exit at spray nozzle front end, the nozzle middle part is provided with nozzle chamber, jet exit communicates with nozzle chamber, the outside of jet exit and nozzle chamber is provided with nozzle body, nozzle chamber one end is provided with the nozzle inducer, and nozzle inducer outside is provided with the nozzle connecting thread.There are the following problems for the technical scheme of above-mentioned patent:
1, the covering of the fan working accuracy of jet exit and surface irregularity are spent lowly, cause particle bond easily, influence spray effect.
2, not clearly design of the transition arcs radius of jet exit, excessive or too small jet exit transition arcs radius all influences the effect of damming.
3, the structure influence of nozzle inducer ammoniacal liquor flusher the ammoniacal liquor stream flow velocity, shape and the direction that produce, be unfavorable for flushing to the bridge tube inwall.
Summary of the invention
The purpose of this utility model will provide a kind of pipe flushing ammoniacal liquor nozzle exactly, and it can make the ammoniacal liquor flusher produce and be beneficial to the ammoniacal liquor stream that the bridge tube inwall is washed.
For realizing this purpose, the coke oven pipe bridge flushing ammoniacal liquor nozzle that the utility model is designed, comprise nozzle body, the middle inner chamber two ends of described nozzle body are respectively arranged with jet exit and nozzle inlet, be provided with the nozzle baffle in the inner chamber of described nozzle inlet, described nozzle baffle has first flow deflector and second flow deflector of relative arranged crosswise, form an integral body by web plate between half inside edge of half inside edge of described first flow deflector and the second adjacent flow deflector, be respectively arranged with guide path on second half inside edge of described first flow deflector and second half inside edge of second flow deflector, the outer ledge of the outer ledge of described first flow deflector and second flow deflector and the inner chamber wall of nozzle inlet are complementary.
Further, described first flow deflector and second flow deflector are 60～80 ° angle arranged crosswise.
Further, the inner chamber of described jet exit is cone-shaped.
Further, the surfaceness of the cone-shaped inner chamber of described jet exit is Ra1.6.
Further, the transition arcs radius between described jet exit and the middle inner chamber is controlled in the scope of 1mm≤R≤1.5mm.
Advantage of the present utility model is: by at nozzle inlet internal fixing nozzle baffle, and the inner chamber of jet exit is designed to cone-shaped, can form the conical surface shape ammoniacal liquor stream of high pressure high flow rate after making ammoniacal liquor stream through the ammoniacal liquor nozzle, utilize this conical surface shape ammoniacal liquor stream evenly to spray, reach the purpose of energy-conserving and environment-protective the bridge tube inwall.
Description of drawings
