Description

Technical Field

[0001] The utility model relates to the technical field of tubular heat exchangers, in particular to a high-temperature steam silencing tubular heat exchanger. Background Art

[0002] At present, the hot water for bathing in a bath is generally filled with cold water in the bath first, and then a steam pipe is directly inserted to heat the cold water with steam. During the bathing process, if the water temperature is low, the water needs to be heated at any time. During the heating process, since the length of the steam pipe inserted into the water is relatively long, the high-temperature steam encounters cold water and generates a vibration phenomenon, causing the pipe to vibrate at a high frequency and emit harsh noises, which makes people unbearable.

[0003] For example, the Chinese patent with the publication (announcement) number CN2884114Y discloses a high-temperature steam silencing tubular heat exchanger, which includes an exchanger body with an inner cavity. A steam inlet and a cold water inlet are provided at one end of the exchanger body, and a warm water outlet is provided at the other end. A jet pipe is installed at the steam inlet, and a partition is provided in the inner cavity of the exchanger body, and a plurality of water-permeable holes are provided on the partition.

[0004] Although the above technical solution solves the corresponding technical problems, the above technical solution still has the following defects:

[0005] The steam of the above technical solution is introduced from the steam inlet, but the inlet gradually decreases from large to small. When the steam is ejected, the flow rate increases, which will make the noise louder. At the same time, it is not convenient to maintain the inside of the exchanger, so the practicability is reduced. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a high-temperature steam silencing tubular heat exchanger, which not only has a spiral silencing retaining ring arranged on the inner wall of the inlet pipe, which can play a silencing role when steam is introduced, but also when the steam passes through the conical silencing holes on the silencing block, due to the conical design of the conical silencing holes, the steam flows from a small aperture to a large aperture, which will greatly reduce the flow rate of the steam, and thus also reduce the noise. At the same time, by pulling the sliding pin and making the sliding pin disengage from the clamping groove on the exchanger housing, the detachable end cover can be conveniently disassembled, so it is convenient to clean or maintain the inside of the exchanger housing, thereby improving the practicability of the utility model.

[0007] In order to achieve the above purpose, the main technical solutions adopted by the utility model include:

[0011] For the above-mentioned high-temperature steam silencing tubular heat exchanger, wherein, a spiral sound-absorbing retaining ring is arranged on the inner wall of the inlet pipe.

[0012] For the above-mentioned high-temperature steam silencing tubular heat exchanger, wherein, the clamping and fixing assembly includes a mounting seat fixedly connected to the mounting ring, a sliding clamping pin is slidably connected to the mounting seat, a sleeve spring is sleeved on the sliding clamping pin, and a clamping groove matching the sliding clamping pin is opened on the exchanger housing at a position corresponding to the sliding clamping pin.

[0013] For the above-mentioned high-temperature steam silencing tubular heat exchanger, wherein, a number of conical sound-absorbing holes arranged at equal distances are opened on the sound-absorbing block.

[0014] For the above-mentioned high-temperature steam silencing tubular heat exchanger, wherein, a sealing inner ring matching the exchanger housing is also fixedly connected to the side surface of the detachable end cover.

[0015] The utility model at least has the following beneficial effects:

[0016] The high-temperature steam silencing tubular heat exchanger provided by the utility model not only has a spiral sound-absorbing retaining ring arranged on the inner wall of the inlet pipe, which can play a sound-absorbing role when steam is introduced, but also when steam passes through the conical sound-absorbing holes on the sound-absorbing block, due to the conical design of the conical sound-absorbing holes, the steam flows from a small aperture to a large aperture, which will greatly reduce the flow rate of the steam, and thus also reduce the noise. At the same time, by pulling the sliding clamping pin and making the sliding clamping pin disengage from the clamping groove on the exchanger housing, the detachable end cover can be conveniently disassembled, so as to facilitate the cleaning or maintenance of the inside of the exchanger housing, thereby improving the practicability of the utility model.
