Description

Technical Field

[0001] This utility model belongs to the field of dilution tank technology, and in particular relates to a tank bottom heating module for dilution tanks. Background Technology

[0002] Existing dilution tanks have cooling coils at the inner edge, but lack heating at the bottom, which can lead to material sedimentation and difficulty in uniform mixing. At the same time, the bottom of the tank heats up slowly, affecting the reaction rate or dissolution efficiency. Therefore, it is necessary to install an active heating module at the bottom of the tank, and most of them now use steam coils for heating.

[0003] Most current steam coils use parallel or spiral coils, which can lead to poor condensate drainage, potentially causing water hammer and reduced thermal efficiency. They can also generate vibration and noise, and even damage the pipes, hindering steam flow and reducing heat exchange efficiency. Furthermore, existing steam coils rely on direct welding or simple supports for fixation, which can cause instability due to thermal stress and vibration, affecting their service life and making maintenance and replacement difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a bottom heating module for a dilution tank. By designing a turbine-shaped coil with a low inner ring and a high outer ring as a steam coil, condensate can be quickly discharged by gravity, avoiding water hammer efficiency and ensuring heat exchange effect. While ensuring a relatively short steam flow path, it also ensures a large coverage area, reduces pressure drop, avoids the existence of heating blind spots, ensures uniform heating, and improves mixing effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a bottom heating module for a dilution tank, including a heating module body and a feed pipe installed at the bottom axis of the dilution tank;

[0007] The heating module includes a steam coil and a mounting bracket;

[0008] The steam coil is a spiral heat exchange tube with a constant pitch worm gear trajectory, and the height of the steam coil decreases gradually from the outer ring to the inner ring along the worm gear line.

[0009] One end of the outer ring of the steam coil is connected to a downward-facing steam inlet pipe, and one end of the inner ring of the steam coil is connected to a downward-facing condensate outlet pipe.

[0010] The mounting frame consists of several support frames, which are arranged in a ring and evenly spaced between the steam coil and the bottom of the dilution tank.

[0011] The support frame includes a support edge, one end of which is provided with an arc-shaped retaining edge with an inverted U-shape structure. Several arc-shaped retaining edges of the support frame are all fitted onto the top of the feed pipe. A bracket is welded and fixed to the other end of the support edge, and the bracket is fixed to the inner bottom surface of the dilution tank.

[0012] The steam coil is movably mounted on the support sides of several support frames, and several U-shaped hoops are fixed on the support sides, with the U-shaped hoops fitted onto the steam coil.

[0013] Furthermore, the bottom of the dilution tank is provided with a set of preset openings, and the steam inlet pipe and the condensate outlet pipe pass through the preset openings and are welded and fixed at the connection.

[0014] Furthermore, the top of the feed pipe extends beyond the bottom of the dilution tank, and the arc-shaped edges of several of the support frames are arranged in sequence.

[0015] Furthermore, the support edges are distributed at an angle at the bottom of the dilution tank, and several contact points are formed between the steam coil and the support edges.

[0016] Furthermore, the U-shaped hoops on the support edge are set in two batches, and the two batches of U-shaped hoops are respectively fixed on opposite sides of the support edge.

[0017] Furthermore, the U-shaped hoop is provided with a high-temperature resistant soft pad, which is in contact with the peripheral side of the steam coil.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model uses a turbine-shaped coil with a low inner ring and a high outer ring as a steam coil. It can quickly discharge condensate by gravity, avoid water hammer efficiency and ensure heat exchange effect. While the steam flow path is relatively short, it ensures a large coverage area, reduces pressure drop, avoids the existence of heating blind spots, ensures uniform heating and improves mixing effect.

[0020] 2. This utility model, through the design of a novel support frame, provides segmented and modular support, ensuring the positional stability of the steam coil. The combination with the feed pipe facilitates the positioning and installation of the support frame. Furthermore, the support frame itself has an inclination, which facilitates the concentric positioning of the steam coil, making installation easier. It also has thermal expansion compensation capabilities, avoiding deformation problems caused by thermal expansion and contraction, thereby improving positional stability and service life.
