Embodiment 1

[0035] The invention provides a spray steam generator, such as figure 1 As shown, it includes: an upper header 100, a water supply pipeline 211, four nozzles 200 and a pipe row 300, wherein the water supply pipeline 211 and the four nozzles 200 form a spraying device, and the water supply pipeline 211 is located in the middle of the upper header , one end of which is welded to the side wall of the upper header 100 through a flange, and the other end 212 is fixed to the lower wall of the upper header through a base 213 . Those skilled in the art will understand that the water supply pipeline can also be fixedly arranged in the upper header by other fixing methods in the field, thereby ensuring the safety of the entire device; the water supply pipeline 211 can be connected to a water pump for supplying water, and the other end 212 can be a closed end or can be connected to a nozzle; the pipe row 300 is arranged under the upper header 100, and communicates with the upper header 1...

Embodiment 2

[0038] The invention provides a spray steam generator, such as figure 2 As shown, on the basis of Embodiment 1, this embodiment further includes a lower header 400. The lower header 400 communicates with the pipe row 300 through a plurality of interfaces, and is used to receive the unvaporized liquid in the steam generator. The lower header 400 is provided with an outlet pipe 410 to discharge the liquid water in the lower header, and a drain valve 500 is provided on the outlet pipe 410 to ensure the lower header while discharging the liquid water in the lower header. The steam present in the tank is not vented, thus ensuring maximum utilization of the steam throughout the device without leakage.

Abstract

The invention provides a spray type steam generator. The spray type steam generator comprises an upper collecting box and a pipe array communicated from top to bottom, and a spraying device arranged in the upper collecting box, wherein the spraying device is connected with a water source for supplying water in a spraying mode; a steam outlet and a joint are formed in the upper collecting box; the pipe array is connected with the upper collecting box through the joint to be communicated with the interior of the upper connecting box, and is used for vaporizing water sprayed out by the spraying device when the pipe array is heated. The spray type steam generator has the advantages of safety, reliability, high heat efficiency, fast steam generation, high automation degree and low operation cost.

Description

technical field [0001] The invention relates to the technical field of steam boilers, in particular to a spray-type steam generator. Background technique [0002] In the prior art, a boiler is usually used to generate steam, and then the generated high-temperature and high-pressure steam is exchanged through a heat exchanger to provide heating for buildings. Boilers in the prior art usually use coal or natural gas as the main heat source for heating the boiler, which further promotes the continuous evaporation of circulating water in the boiler to generate a large amount of steam. Structurally, boilers in the prior art usually have a huge heating water tank in direct contact with the heat source, and are provided with a make-up water pump to maintain the water level inside the heating water tank. In actual use, if the safety valve fails due to aging, the internal pressure of the boiler will rise sharply, resulting in an explosion with huge energy. Even if the water storage ...
