Description

Technical Field

[0001] This utility model relates to the field of spray guns, specifically a denitrification spray gun. Background Technology

[0002] The spray gun is specifically designed for denitrification engineering. It is a dual-fluid atomizing spray gun, and its atomization principle is two-stage crushing + air mixing + airflow friction. The nozzles used in the denitrification spray gun are divided into S-type and F-type according to flow rate and spray shape. The S-type nozzle produces a 20-degree narrow-angle solid cone spray shape, while the F-type nozzle produces a wide-angle fan spray shape.

[0003] For example, the authorized patent with publication number CN219355762U (Double-layer denitrification spray gun for waste-to-energy plant): It facilitates cooling of the denitrification spray gun while minimizing the increase in oxygen content in the boiler, making it highly practical. It includes a denitrification spray gun body and a cooling cylinder, which is fitted onto the denitrification spray gun body. A cooling mechanism is installed on the cooling cylinder. The cooling mechanism includes a water tank, which is fixedly connected to the bottom of the cooling cylinder. A water pump is installed on the water tank, with its input end connected to the water tank and its output end connected to a water inlet pipe. The top end of the water inlet pipe is connected to the cooling cylinder, and the right end of the cooling cylinder is connected to a recovery pipe. The bottom end of the recovery pipe is connected to the water tank, and a cooler is installed at the bottom of the water tank. A cooling mechanism is installed on the cooling cylinder, and the drive mechanism includes a mounting frame, which is fixedly connected to the cooling cylinder. A first motor is installed on the mounting frame, and the output pipe of the first motor passes through the mounting frame and is fixedly connected to a power gear.

[0004] The aforementioned existing nozzles are bulky and inconvenient to assemble and control. Furthermore, the spray gun cannot be directional controlled, making it inflexible in use. The spray pattern is also relatively simple and not easy to adjust according to the spray range and requirements. Utility Model Content

[0009] In a further embodiment, the bottom of the nozzle is provided with a secondary discharge head, and the nozzle is rotatably connected to the connector.

[0010] In a further embodiment, a mounting sleeve is provided at the center of the top of the spray hood, and the mounting sleeve is inlaid and assembled with the end of the main guide pipe.

[0011] In a further embodiment, the spray hood is configured as a disc-shaped nozzle, and multiple nozzles are evenly arranged on the sides of the spray hood.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The first connecting pipe and the second connecting pipe of this utility model are connected by a corrugated pipe. The corrugated pipe can control the direction of the first connecting pipe and the second connecting pipe, so that the spray gun angle can be adjusted.

[0014] The nozzle of this utility model has a connector at one end, which is connected to the end of the second connecting pipe by a screw head for easy installation and disassembly. The other end of the nozzle is connected to the mounting sleeve on the top of the spray hood by a main pipe, which facilitates the installation and disassembly of the spray hood. Multiple nozzles are provided on the side of the spray hood, which allows for multi-directional spray control. Attached Figure Description
