1. Nozzles for burners (military and civil)
2. Non-burner nozzles
According to the function of the nozzle, the nozzle can be roughly divided into: spray nozzle, fuel injection burner, sandblast nozzle, and special nozzle.
Classified by material, it can be divided into: metal nozzle, plastic nozzle, ceramic nozzle, alloy nozzle.
Classified by industry, it can be divided into: petrochemical nozzles, agricultural nozzles, textile nozzles, paper nozzles, printing nozzles, environmental protection (desulfurization, denitrification, denitrification, dust removal, etc.) nozzles, spray nozzles, iron and steel metallurgical nozzles, electronic nozzles, food nozzles.
According to the shape classification, it can be divided into hollow cone nozzle, solid cone nozzle, square nozzle, rectangular nozzle, oval nozzle, fan nozzle, column flow (direct current) nozzle, two-fluid nozzle, multi-fluid nozzle and so on.
Nozzles for special industries: flame spray nozzles, Texaco nozzles, granulation nozzles, etc.
In short, the nozzle application is very wide. It involves almost every field.
1) Cleaning (also called surface cleaning)
a. Pre-treatment chemical cleaning of automobiles, motorcycles, household appliances, etc., and automobile cleaning;
b. High-pressure cleaning of the inner surface of bottles, tanks and barrels, such as beer bottles, oil drums, large-size tanks, etc.;
c. Chemical cleaning of the outer surface of the circuit board.
2) Spraying (also called painting)
a. Phosphating, passivation, degreasing, etc. on the surface of metal parts;
b. Spray paint can be divided into mechanical or air atomization as the main method, and electrostatic atomization as the auxiliary combination method, which is used for metal and non-metal
Belonging to equipment, furniture, interior decoration, etc.;
c. Tablet coating, inkjet printing, spray printing and dyeing.
a. Cooling towers, such as circulating water in power plants, ground gas turbine inlet cooling (using water film or other coolants), etc.;
b. Conveyor belt cooling.
4) Fire prevention
a. Storage tank;
b. Drilling platform, etc.
a. Humidification of workshops and storage rooms;
b. Humidification in textile workshops and printing plants to prevent static electricity.
6) Dust removal
a. Garbage sweeper trucks press dust on the ground and sprinklers (basically use narrow-angle fan nozzles);
b. Remove dust from the cupola;

b. Spray release agent;
c. Lubrication of die on large forging press;
d. Lubrication of conveyor belts or conveyor chains;
8) Gas regulation
a. Air conditioning in the washing and spray booth;
b. S02 is removed, N02 is controlled;
c. Scrubbing gas, such as deoxygenation, etc.
9) Preparation of powder (agent, powder)
a. Chemical, food, medicine, ceramics and other powdered products are prepared in spray drying equipment;
b. Powder metallurgy in the preparation of powders of metals, alloys and metal compounds.
10) Agriculture and gardens, such as spraying pesticides and fertilizers on agricultural and forest crops, spraying irrigation for nurseries and gardens, etc.
11) Daily life such as showering, spraying hair gel and mousse during haircuts, spraying insects and disinfectants on various occasions.
12) High pressure cleaning, ultrasonic cleaning, defoaming, cooling and quenching, water cooling, scrubber, fire prevention, and other surface cleaning processes.
