Description

Technical Field

[0001] This utility model relates to a cooler for insulating materials, belonging to the field of cooling equipment. Background Technology

[0002] Spray dryers are used in the production of insulating materials. These dryers are energy-intensive, requiring high-temperature hot air to rapidly evaporate moisture. Some heat is discharged with the exhaust gas, resulting in a thermal efficiency typically of only 30% to 50%, necessitating additional equipment to improve efficiency. Furthermore, the yield of spray dryers is only around 80%, meaning some material is carried out with the exhaust gas, requiring equipment for material recovery or treatment. Summary of the Invention

[0003] Based on the problems described in the background, the problem that this utility model aims to solve is:

[0004] How to improve the utilization rate of heat in hot and humid air and subsequent condensate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cooler for insulating materials includes a cooler shell, an air heat exchange section, and a condensate heat exchange section. The air heat exchange section is located at the upper interior of the cooler shell, and the condensate heat exchange section is located at the lower interior of the cooler shell. The air heat exchange section adopts a plate-like heat exchange system and is divided into a high-temperature side and a low-temperature side. The bottom of the high-temperature side has an open channel that communicates with the interior space of the cooler shell. The high-temperature side inlet and the low-temperature side outlet are located at the upper part of the air heat exchange section, and the low-temperature side inlet is located at the lower part of the air heat exchange section. Hot air enters the high-temperature side through the high-temperature side inlet and then leaves the air heat exchange section through the open channels of each high-temperature side, and is discharged through the air outlet at the top of the cooler shell. The condensate heat exchange section adopts a shell-and-tube heat exchange system and has tube-side components immersed in condensate. The bottom of the cooler shell has a condensate outlet, and both ends of the tube-side components have tube-side outlets and tube-side inlets that penetrate the cooler shell. The tube-side outlet is connected to the low-temperature side inlet.

[0007] Hot air enters each high-temperature side through the high-temperature inlet. After exchanging heat with the adjacent low-temperature side, the hot air, mixed with water vapor, cools down to generate low-temperature air and condensate. The air and condensate are discharged together into the cooler shell through an open channel. Unlike ordinary condensate and air separation, the air and condensate move in the same direction within the high-temperature side. Air and gravity cause the condensate droplets to accelerate downwards and converge. When the air flows upwards to the air outlet, the condensate already has a certain initial velocity, easily overcoming the upward force of the air and converging at the bottom of the cooler shell. At the same time, the tube-side components are completely immersed in the condensate, with a condensate outlet at the bottom to directly supply the cooled condensate to the water-requiring process before drying, and can also recover a small amount of material from the condensate.

[0008] Preferably, the inner walls on both sides of the high-temperature side are provided with guide plates running from top to bottom. The guide plates help to collect condensate faster and better, resulting in larger condensate droplets that are more difficult for air to carry out of the cooler.

[0009] Preferably, the tube assembly has a support plate in the middle.

[0010] Preferably, a support base is connected to the lower part of the cooler housing.

[0011] Preferably, a level gauge is provided at the bottom of the cooler housing.

[0012] The beneficial effects of this utility model are:

[0013] This invention efficiently recovers unused heat from spray dryers; it employs a plate-type heat exchange system with an open channel design, ensuring high heat exchange efficiency while improving the separation of air and condensate. No subsequent liquid separation buffer tank is required. Attached Figure Description

The air heat exchange section 2 is located at the upper interior of the cooler shell 1, and the condensate heat exchange section is located at the lower interior of the cooler shell 1. The air heat exchange section 2 adopts a plate-type heat exchange system and is divided into a high-temperature side 21 and a low-temperature side 22. The bottom of the high-temperature side 21 has an open channel 24 that communicates with the internal space of the cooling shell 1. The high-temperature side inlet 23 and the low-temperature side outlet 26 are located at the upper part of the air heat exchange section 2, and the low-temperature side inlet 25 is located at the lower interior of the air heat exchange section 2.

The condensate heat exchange section adopts a shell-and-tube heat exchange system. The condensate heat exchange section is equipped with tube-side components 3, which are immersed in condensate. The bottom of the cooler shell 1 is provided with a condensate outlet 33. The tube-side components 3 are provided with tube-side outlets 31 and tube-side inlets that penetrate the cooler shell 1 at both ends. The tube-side outlets 31 are connected to the low-temperature side inlet 25.

[0022] Hot air enters the air heat exchange section through the high-temperature side inlet 23, exchanges heat with the low-temperature side 22, and then enters the cooler through the open channel 24. At this time, the cooled air separates from the condensate, the condensate falls to the bottom of the cooler, and the air is discharged through the exhaust outlet 27. Coolant enters the tube-side assembly 3 through the tube-side inlet, exchanges heat with the condensate, and then enters the low-temperature side 22 through the low-temperature side inlet 25. After heat exchange, it is discharged through the low-temperature side outlet 26.
