Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, in particular to a heat storage type heat exchanger. Background Art

[0002] In industries such as metallurgy, electricity, petroleum, and chemicals, waste gas treatment equipment is the key to energy conservation and emission reduction. Among them, the heat storage heat exchanger, as an important component of waste gas treatment equipment, achieves short-term energy storage through heat storage media, recovers waste heat in the waste gas and reuses it to preheat cold air, thereby achieving effective use of energy.

[0003] Traditional heat storage heat exchangers are prone to clogging after long-term use and need to be regularly inspected and repaired, but there are many inconveniences in replacing the filler. Since the filler is directly filled inside the heat exchanger, it is often necessary to dismantle the entire heat exchanger or part of the structure when replacing it, which not only increases the difficulty of replacement, but may also affect the performance and stability of the heat exchanger. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a heat storage type heat exchanger to improve the convenience of replacing fillers.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heat storage heat exchanger, including a tank body and an airflow duct for air flow in and out, the tank body is provided with a support platform, and a plurality of layers of filling bins are stacked on the support platform from top to bottom, each layer of filling bins is filled with fillers, and a vent is provided at the bottom of the filling bin, and a lifting structure is provided on the filling bin, and the filling bin can be lifted up by a lifting rod and a lifting structure; the tank body is composed of a main body and a cover body detachably installed on the top of the main body; by modularly stacking the fillers with the filling bins, the removal and replacement of the fillers are facilitated, the workload of inspection and maintenance is reduced, and the performance of the heat exchanger is indirectly guaranteed.

[0006] Preferably, the lifting structure includes a lifting hole, which is opened along the axial direction of the filling bin, and is opened on the side wall of the filling bin and is provided with a plurality of holes along the circumferential direction of the filling bin.

The clamping portion can be fitted and clamped in the lifting hole and can move relatively along the axial direction of the lifting hole under the guidance of the lifting hole. When the clamping portion moves to the bottom of the corresponding filling bin, the lifting rod rotates at a certain angle and then lifts up, and the clamping portion presses against the bottom of the filling bin and drives the filling bin to move up. An active gap is provided between adjacent layers of filling bins for the lifting rod to move. By rotating the lifting rod at the corresponding position and interfering with the ground of the filling bin, several layers of the filling bin can be taken out from top to bottom at the same time, which is convenient for quick inspection and replacement of the filler.

[0007] Preferably, the lifting hole consists of a circular hole and a clamping hole, and a clamping hole is symmetrically opened on both sides of the circular hole to limit the rotation of the lifting rod.

[0008] Preferably, the lifting structure also includes a lifting groove, and a lifting groove is provided at the bottom of the filling bin, and there is an interlaced area between the groove surface of the lifting groove and the cross-section of the lifting hole. When the clamping part moves to the bottom of the corresponding filling bin, the lifting rod rotates a certain angle and then lifts up, and the clamping part can be buckled into the lifting groove; to avoid the filling bin falling off due to the rotation of the clamping part during the lifting process, thereby reducing safety hazards.

[0009] Preferably, the area of ​​the pulling groove is larger than that of the clamping portion to facilitate the clamping of the clamping portion.

[0010] Preferably, the lifting ring and the clamping portion are located in the same plane to facilitate the grasping of the rotational position of the clamping portion.

[0011] Preferably, a top foot is provided on the top of the filling bin, and a bottom groove is provided on the bottom of the filling bin. The top foot of the filling bin of the next layer can be fitted and buckled in the bottom groove of the upper layer. Each filling bin is provided with multiple top feet and bottom grooves along the circumferential direction, and the height of the top foot is greater than the depth of the bottom groove to form a gap between the upper and lower filling bins.

[0012] Preferably, a plurality of the support platforms are spaced apart around the circumference of the tank body.

[0013] Preferably, a discharge pipe is provided at the bottom of the main body to facilitate the discharge of filler fragments falling out of the vent hole.

[0014] The technical effect of the utility model is that the fillers are modularly stacked in the filling bins, so that the replacement of the fillers is convenient, the workload of inspection and maintenance is reduced, and the performance of the heat exchanger is indirectly guaranteed.

A discharge pipe 17 is also provided on the bottom of the main body 11. The first air inlet pipe 13, the second air inlet pipe 14, the second air outlet pipe 15, the first air outlet pipe 16 and the discharge pipe 17 are all provided with a stop valve. The stop valve is a prior art, and the type is selected according to the different states of the objects passing through.

[0025] Furthermore, a support platform 2 is fixedly connected to the side wall of the tank body 1 near the bottom, and the support platform 2 is arranged at intervals in the circumferential direction of the tank body 1. Three layers of filling bins 3 are placed on the support platform 2 in sequence from bottom to top. The filling bin 3 is a basin-shaped structure, and a vent hole 4 is opened at the bottom, and is filled with a filler. The filler is a prior art, a commonly used heat storage medium, and can be a ceramic heat storage medium, a metal heat storage medium, or a metal-ceramic mixed medium.

[0026] Specifically, a lifting hole 5 is provided on the side wall of the filling bin 3. The lifting hole 5 is a through hole, and three lifting holes 5 are vertically provided around the circumferential direction of the filling bin 3. The lifting hole 5 is in a candy-like shape, and is composed of a circular hole 51 and a clamping hole 52. A clamping hole 52 is symmetrically provided on both sides of the circular hole 51. The clamping hole 52 is a rectangle with a width smaller than the diameter of the circular hole 51. A lifting groove 6 is provided in the bottom hole edge area of ​​each lifting hole 5 of the filling bin 3. The shape of the lifting groove 6 is similar to that of the lifting hole 5, and it is a blind hole. The central circular area of ​​the lifting groove 6 coincides with the lifting hole 5, and the rectangular areas on both sides thereof are vertically staggered with the clamping holes 52 of the lifting hole 5.

[0027] Furthermore, a lifting rod 7 is inserted into the lifting hole 5, and the lifting rod 7 includes a round rod 71, a clamping portion 72 and a hanging ring 73.
