Description

Technical Field

[0001] The utility model relates to the technical field of hot dry steam humidifiers, in particular to a surrounding heating type spray pipe used for hot dry steam humidifiers. Background Art

[0002] A hot dry steam humidifier is a special type of humidifier that humidifies indoor air by generating dry hot steam through heating. This humidifier combines the two processes of heating and evaporation to effectively increase indoor humidity and improve air quality. Its working principle is relatively straightforward: first, the water inside the humidifier is heated to boiling to produce steam. Subsequently, it passes through a steam-water separation device to ensure that only dry steam is released into the room. This device can effectively prevent condensed water from entering the air conditioning system and ensure the purity of the steam.

[0003] Hot dry steam humidifier has many significant advantages. First, because it uses an external steam source, no other energy loss is required during the heating process, so it is highly economical. It is synchronized with the air conditioning system, beautiful and durable. Furthermore, the hot dry steam humidifier adopts isothermal humidification, with high humidification efficiency and stable and reliable operation. In addition, a variety of control methods enable this humidifier to adapt to different working environments and achieve high-precision control.

[0039] It also includes a left end cover 2 matched with the left end of the nozzle body 1, and a right end cover 3 matched with the right end of the nozzle body 1; a left end cover through hole 201 capable of allowing dry steam to pass through is provided at the axial position of the left end cover 2, and a fourth arc-shaped groove 202 capable of buckling with the first arc-shaped groove 106 is provided on the inner wall of the left end cover 3, and the first arc-shaped groove 106 and the fourth arc-shaped groove 202 are buckled to form a first drainage channel 4; a fifth arc-shaped groove 301 capable of buckling with the second arc-shaped groove 107 and a sixth arc-shaped groove 302 capable of buckling with the third arc-shaped groove 108 are provided on the inner wall of the right end cover 3; the second arc-shaped groove 107 and the fifth arc-shaped groove 301 are buckled to form a second drainage channel 5, and the third arc-shaped groove 108 and the sixth arc-shaped groove 302 are buckled to form a third drainage channel 6;

[0040] The first heating channel 102 is connected to a heat source inlet 109, and the fourth heating channel 105 is connected to a heat source outlet 110;

[0041] The nozzle body 1 is provided with a plurality of nozzles 111 .

[0042] Working principle:

[0043] The dry steam enters the hollow cavity 101 through the through hole 201 of the left end cover. Under the continuous input of pressure, the dry steam fills the hollow cavity 101 and continues to be output outward along the nozzle 111, thereby achieving the purpose of humidifying the external air.

[0044] like Figure 7 As shown, in order to ensure that the dry steam in the hollow cavity has a certain temperature, an external heat source, such as hot steam, enters the first heating channel 102 through the special source inlet, enters the second heating channel 103 after being reversed through the second drainage channel 5, and then enters the third heating channel 104 after being reversed through the first drainage channel 4, and then enters the fourth heating channel 105 after being reversed through the third drainage channel 6, and finally is discharged to the external pipeline through the heat source outlet 109, thereby realizing the cyclic preheating of the dry steam in the hollow cavity 101.

[0045] It should be noted that, in order to facilitate the connection between the nozzle and the external dry steam input device, the present embodiment adds an outward extension tube 203 to the left end cover 2, and a thread is provided on the outer wall of the extension tube to facilitate the screw connection with the dry steam input pipe.

This structure can be easily connected to an external heat source pipe to facilitate the entry and discharge of the heat source, thereby forming a thermal cycle, and can continuously preheat the hollow cavity 101.

[0048] Specifically, the heat source inlet 109 is adjacent to the left seal of the first heating channel 102, and the heat source outlet 110 is adjacent to the left seal of the fourth heating channel 105; this structure can ensure that no hot gas stays on the left side of the first heating channel 102 or the fourth heating pipe 105, thereby causing non-circulation.

[0049] In addition, in this embodiment, the first heating channel 102, the second heating channel 103, the third heating channel 104, the fourth heating channel 105, the first drainage channel 4, the second drainage channel 5 and the third drainage channel 6 have the same inner diameter.

[0050] Specifically, the structure can ensure that the flow rate at each location in the heating pipeline is balanced, thereby ensuring the balance of heat.

[0051] The inner diameter of the hollow cavity 101 is greater than the inner diameter of the first heating channel 102 .

[0052] As an optimization of the nozzles 111 in this embodiment, the nozzles 111 are arranged in a straight line and are placed on the side wall of the nozzle body 1 corresponding to between the third heating pipe 104 and the fourth heating pipe 105 .

[0053] As a specific embodiment of the present solution, there are 12 nozzles 111 which are arranged at equal intervals.

[0054] It should be noted that the nozzle body 1, the left end cover 2, and the right end cover 3 in this embodiment are all made of stainless steel, which is corrosion-resistant and high-pressure-resistant, thereby effectively extending the service life of the nozzle.

[0055] As a connection method between the left end cover 2, the nozzle body 1 and the right end cover 3 in this embodiment, threaded holes 7 are respectively provided on the left end side wall and the right end side wall of the nozzle body 1, and correspondingly, threaded through holes 8 are respectively opened on the left end cover 2 and the right end cover 3, and the left end cover 2 and the right end cover 3 are screwed to the nozzle body 1 by screws 9.

[0056] It should be noted that in order to ensure the airtightness between the left end cover 2 and the nozzle body 1, and between the right end cover 3 and the nozzle body 1, conventional sealing means in the art may be used for sealing, such as providing a sealing ring at the gap, or applying sealant.

[0057] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
