Abstract

The invention provides a concentric double-layer sprayer, which has a hollow sleeve shape, wherein one end of the sprayer is provided with a medium inlet, and the other end of the sprayer is closed; a nozzle is arranged on a side wall of the sprayer and is a gap which is annularly formed along the circumference of the sprayer; and a secondary nozzle is arranged on the side wall of the sprayer along the length direction. The concentric double-layer sprayer is a novel sprayer suitable for a spraying device and is used for putting out a fire, diluting and covering leakage media and the like under temperature reduction, dust removing or emergency of equipment. A double-injection cavity and dual nozzles are arranged on the sprayer, so that concentric double-layer spraying is realized, and the aim of replacing or optimizing the sprayer of the spraying system is fulfilled. The sprayer has a wide spraying range; the spraying angle is adjustable, and different spraying angles and ranges on each layer can be realized; the concentric double-layer sprayer has the characteristics of large density of sprayed water mist, high water flow, and simple structure, is convenient to install and regulate, has an antifouling design and is hardly blocked, and the concentric double-layer sprayer is high in operating maintenance, attractive in spray appearance, and particularly suitable for overall coverage of large and medium equipment and devices.

Description

technical field

[0001] The invention relates to a spraying device for chemical production, in particular to a water mist spraying head with a new structure that realizes concentric double-layer water spraying with one spraying head. Background technique

[0002] At present, in the storage tank areas of various chemical media in chemical production, such as liquid ammonia spherical tanks, gas storage tanks, etc., various spray devices are generally installed for cooling equipment, dust removal or fire extinguishing in emergency situations. Dilution and covering of leakage medium, etc. Traditional sprinklers are generally implemented by installing and arranging various water pipelines on the equipment, and then installing nozzles on the pipelines. In the sprinkler system, the sprinkler is the key equipment, which has various types and various structures. Among the existing types of nozzles, most nozzles have a spraying diameter coverage range of 2-4 meters, forming water cu...
