TECHNICAL FIELD

[0001] The utility model belongs to the technical field of boiler, concretely relates to a kind of integrated boiler pressure discharge mechanism. BACKGROUND

[0002] During the operation of the boiler system, the heat generated by fuel combustion can cause water or other working media to evaporate, resulting in steam. As the steam accumulates, the pressure inside the boiler will continue to rise. To prevent the pressure from exceeding the design limit, it is necessary to release the excess pressure through certain discharge mechanisms. Boiler pressure discharge is crucial for ensuring the safe operation of the boiler system, as excessive pressure can lead to boiler explosions or other serious accidents.

DETAILED DESCRIPTION

[0019] This embodiment is a kind of integrated boiler pressure discharge mechanism, and its structure schematic view is as Figures 1-4As shown, including exhaust pipe 1, the inner wall of exhaust pipe 1 is fixed with annular plate 2, the end face of annular plate 2 is inclined, the bottom end of exhaust pipe 1 is threadedly connected with butt joint pipe 3, butt joint pipe 3 is installed on the boiler, the upper side of annular plate 2 is provided with valve core 4, valve core 4 is in abutment with the inclined surface of annular plate 2, the bottom surface of valve core 4 is fixedly connected with valve rod 5, the inner wall of annular plate 2 is fixedly connected with leakage plate, the bottom end of valve rod 5 penetrates through leakage plate and is fixedly connected with pressure plate 6, spring 18 is sleeved on the side wall of valve rod 5, the bottom surface of pressure plate 6 is provided with plugging assembly, the top end of exhaust pipe 1 is provided with flow guide assembly.

[0020] As shown in Figure 2 and Figure 3 , the plugging assembly includes a support plate 8 fixedly connected to the inner wall of the exhaust pipe 1, a plurality of plugging blocks 9 fixedly connected to the top surface of the support plate 8, and a plurality of through holes 7 formed in the top surface of the pressure plate 6, the plugging blocks 9 being adapted to the through holes 7. The side walls of the plugging blocks 9 and the through holes 7 are inclined.

[0021] The use of the plugging assembly in conjunction with the pressure plate 6 can seal the exhaust pipe 1, preventing gas leakage when the pressure is too low, and can also use the pressure of the boiler to lift the pressure plate 6 upward when the internal pressure of the boiler is too high, allowing water vapor to be discharged through the through holes 7. The tapered structure of the plugging blocks 9 and the through holes 7 increases the contact area between them, further improving the sealing performance.

[0022] As shown in Figure 2 and Figure 4 , the flow guide assembly includes a tapered tube 10 fixedly connected to the top end of the exhaust pipe 1, a tapered block 11 disposed inside the tapered tube 10, a plurality of horizontal plates 12 fixedly connected between the tapered block 11 and the tapered tube 10, and a collection assembly disposed on the side wall of the tapered tube 10.

[0023] The use of the flow guide assembly to condense water vapor has the following benefits:

[0024] Water vapor has a high thermal energy at high temperatures, and direct discharge into the environment can pose a risk of burns to personnel and equipment. Condensing water vapor into water droplets can significantly reduce this risk; the condensation process can more stably control pressure release, avoiding pressure fluctuations caused by sudden steam discharge, thereby improving system stability and safety; direct discharge of water vapor into the atmosphere can increase air humidity and potentially affect local climate. Condensing water vapor into water droplets and recycling can reduce this impact;

[0025] In addition, the condensation filament 13 is made of cotton thread, non-woven fabric or other materials.

[0026] As shown in Figure 2 and Figure 4As shown, the collecting assembly comprises condensation filaments 13 connected between the horizontal plates 12, the baffle 14 is fixedly connected to the inner wall of the tapered pipe 10, a plurality of water outlet holes 15 are formed in the upper side of the baffle 14 on the side wall of the tapered pipe 10, and the water collecting plate 19 is fixedly connected to the outer wall of the tapered pipe 10.

[0027] The water droplets after condensation are collected, so that the utilization rate is increased, for example, the water is used for preheating or other heat energy requirements, so that the energy utilization efficiency of the whole system is improved.

[0028] Working principle: when the pressure in the boiler is too large, water vapor enters the exhaust pipe 1, and the steam pressure pushes the pressure plate 6 to move upward, so that the through hole 7 on the pressure plate 6 is separated from the blocking block 9, and the sealing of the boiler is contacted, the pressure plate 6 moves upward, the valve core 4 is driven to move upward through the valve rod 5, and the spring 18 is stretched, the water vapor passes through the through hole 7 and is discharged from the gap between the valve core 4 and the annular plate 2, so as to achieve the purpose of pressure relief, after the pressure in the boiler is less than the force of the spring 18, the spring 18 drives the valve core 4 to reset, and the exhaust is closed, so as to achieve the purpose of automatic exhaust.

[0029] At the same time of exhaust, the water vapor is guided and dispersed by the tapered block 11, the water vapor is condensed into water droplets by contacting the condensation filaments 13, and falls on the tapered pipe 10, and is collected in the water collecting plate 19 through the water outlet hole 15, so as to avoid that the water vapor is high in temperature when being discharged, and causes a safety hazard, and the water vapor is dispersed and cooled by the guiding and condensing mode.

[0030] All the technical features in the embodiment can be freely combined according to actual needs.

[0031] The above embodiment is a preferred implementation scheme of the utility model, in addition to this, the utility model can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
