Embodiment 1

[0019] see figure 2 Shown is the structural sectional view of the present invention. A supersonic direct heating heater of the present invention comprises:

[0020] A main housing 8 is in the shape of a circular tube, one end of the main housing 8 is fixedly connected to the integral fixed flange 3, and there are evenly distributed holes on the wall surface of the main housing 8 near the end 1 / 4 of the integral fixed flange 3. The water inlet 6, the quantity of the water inlet 6 is 2-6, the best is 4; the other end of the main housing 8 is a water outlet 11; wherein between the critical nozzle 7 and the water outlet 11 is a cylinder Shaped high-pressure mixing chamber 10;

[0021] A nozzle 5 is funnel-shaped, and the nozzle 5 is accommodated in the main housing 8, and the large-diameter end of the nozzle 5 is fixedly connected to the integral fixing flange 3; a critical nozzle 7 is long trumpet-shaped, and the critical The nozzle 7 is fixedly connected to the small diamete...

Embodiment 2

[0026] see image 3 As shown (wherein the same components in the accompanying drawings use the same reference numerals), the present embodiment is basically the same as the first embodiment, the difference is that its main housing 8 is a double-layer structure, including an outer wall 81 and an inner wall 82 A sound-absorbing and vibration-isolation cavity 9 is formed between the outer wall 81 and the inner wall 82, and water inlet holes 4 are evenly distributed on the end of the outer wall 81 close to the integral fixed flange 3, and the number of the water inlet holes 4 is 2-6 , preferably 4.

[0027] When the water enters the high-pressure mixing chamber 10 through the water inlet 4 on the outer wall of the main shell 8 of the heater through the sound-absorbing and vibration-isolating cavity 9 and then from the water inlet 6 on the inner wall of the main shell 8, due to the noise Due to the effect of the vibration isolation cavity 9, the working noise and movement can be f...

Embodiment 3

[0029] see Figure 4 As shown (wherein the same parts in the drawings use the same reference numerals), the present embodiment is substantially the same as the second embodiment, the difference being that one end of the main housing 8 away from the integral fixing flange 3 is affixed with a Conical conical decompression damping body 13, the conical end of the conical decompression damping body 13 extends into the main housing 8 and the tail end is affixed to the main housing 8; the main housing 8 is far away from the integral fixed flange 3 There are water outlets 12 on the wall at one end, the number of the water outlets 12 is 2-6, the best is 4.

[0030] When the water enters the high-pressure mixing chamber 10 through the water inlet 4 on the outer wall of the main shell 8 of the heater through the sound-absorbing and vibration-isolating cavity 9 and then from the water inlet 6 on the inner wall of the main shell 8, due to the noise With the function of the vibration isola...

Abstract

A supersonic directly heated heater is composed of a tubular main shell with one end fixed to a fixing flange, a water inlet near the fixing flange and a water outlet being just its the other end, a funnel-shaped nozzle in the said main shell, and a horn-shaped critical nozzle fixed to the small-diameter end of said funnel-shaped nozzle. Said fixing flange is fixed to the big-diameter end of saidfunnel-shaped nozzle.

Description

technical field [0001] The invention belongs to a rapid hot water heating device, in particular to a high-power supersonic direct-heating heater using steam as a heat source. Background technique [0002] There are two main types of hot water heating systems that use steam as a heat source: indirect heating and direct heating. The indirect heating system is subject to many restrictions in production and application due to its low thermal efficiency, slow heating speed, bulky heat exchanger, and easy scaling and blockage; [0003] Although the direct heating hot water heating system has high thermal efficiency, fast heating speed, small size, and no scaling, but because the process of directly mixing steam with cold water will make huge noise and violent vibration, it is generally only necessary in industrial production, etc. It is only used when a large amount of hot water needs to be heated instantaneously. [0004] Such as figure 1 Shown is a sectional view of an existi...
