Description

Technical Field

[0001] This utility model relates to the field of exhaust cooling, and more particularly to a cooling device suitable for high-temperature exhaust from a furnace. Background Technology

[0002] Inside the high-temperature furnace of the testing equipment, high-temperature steam needs to be discharged. This steam is pollution-free and can be directly discharged into the air.

[0003] High-temperature furnace equipment is large in size and is usually installed in a factory building. The traditional method is to build a high-temperature resistant exhaust pipe inside the factory building. The factory space is relatively large, the construction is difficult, and there are also safety hazards. Therefore, there are strict requirements on the length and layout of the pipes. This traditional exhaust method has the problems of both layout difficulty and high cost. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a cooling device suitable for high-temperature exhaust gas from a furnace, aiming to solve the difficulties in layout and the cost issues caused by the length of the pipes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a cooling device suitable for high-temperature exhaust gas from a furnace, characterized in that it includes a box, and the box is provided with a tortuous flow channel, in which a plurality of nozzles for spraying cold source onto high-temperature steam are provided.

[0006] The beneficial effects of this utility model are:

[0007] The design concept of this utility model is to cool high-temperature steam. As a result, it can eliminate the need for pipelines, solving the safety hazards in factory construction. Secondly, the savings in pipeline layout costs, quantity, and size costs can save a lot of costs for testing institutions. In addition, after using this utility model, there is no need for separate pipeline layout, the assembly difficulty is low, and it also has the advantages of small space occupation and high cooling efficiency.

[0008] To provide a more comprehensive explanation of the specification, this solution is further clarified through this specific embodiment.

[0009] In this specific embodiment, the steam inlet, exhaust outlet, and drain outlet are all located on the side of the housing. The steam inlet is located on the first side of the housing, while the exhaust outlet and drain outlet are located on the second side of the housing. The drain outlet is located below the exhaust outlet. The second side is the opposite side of the housing to the first side.

[0010] In a preferred embodiment, multiple baffles are used inside the chamber to create a meandering flow channel. Adjacent baffles are arranged in an alternating manner inside the chamber, and nozzles are located on the inner wall of the chamber 1, which forms part of the flow channel. The purpose is to increase the flow path of the high-temperature gas inside the chamber and increase the contact time with water, so that the sprayed water mist and high-temperature steam are fully mixed and cooled down quickly.

[0011] In the aforementioned staggered upper and lower partitions, the partition located at the bottom has a gap between it and the bottom of the box, allowing water from the nozzles to flow out from the drain.

[0012] The upper partition is connected to the inner wall of the box at both ends; the top cover, which is part of the box, covers the upper partition and is connected by contact.

[0013] The chamber is also equipped with a temperature sensor, which is installed on the chamber and its detection end is inserted into the chamber and adjacent to the steam inlet. It is used to detect the temperature inside the chamber and whether high-temperature steam has entered the chamber. When high-temperature steam is encountered, the temperature controller controls the cooling water solenoid valve to open the nozzle and start spray cooling.

[0014] An over-temperature protector is also installed near the exhaust port of the enclosure. The detection end of the over-temperature protector is located inside the enclosure and is used to detect the temperature of the fluid in the exhaust port. The over-temperature protector is also connected to the alarm signal. By pre-setting the upper limit of the exhaust temperature, the alarm will sound when the exhaust exceeds the preset temperature.

[0022] The design concept of this utility model is to cool high-temperature steam. As a result, it can eliminate the need for pipelines, solving the safety hazards in factory construction. Secondly, the savings in pipeline layout costs, quantity, and size costs can save a lot of costs for testing institutions. In addition, after using this utility model, there is no need for separate pipeline layout, the assembly difficulty is low, and it also has the advantages of small space occupation and high cooling efficiency.
