Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery systems, and in particular to a waste heat recovery system for roller kilns. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials (such as fruit shells, coal, and wood) are heated in the absence of air to reduce non-carbon components (this process is called carbonization). Then, they react with gases, and the surface is eroded, creating a structure with well-developed micropores (this process is called activation). Because the activation process is a microscopic process, the surface erosion of a large number of molecular carbides is point erosion, resulting in countless tiny pores on the surface of activated carbon.

[0003] In existing technologies, activated carbon products need to be dried to reduce their moisture content. Roller kilns are often used to dry activated carbon, which is relatively fast. However, roller kilns do not completely consume heat, resulting in some heat being wasted, causing unnecessary carbon emissions and resource waste. Therefore, a roller kiln waste heat recovery system is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a waste heat recovery system for roller kilns to solve the problem mentioned in the background art that activated carbon products need to be dried to reduce their moisture content. Roller kilns are often used to dry activated carbon, but roller kilns do not completely consume heat, resulting in some heat being wasted and causing unnecessary carbon emissions and resource waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery system for a roller kiln, comprising a drying chamber, a control box arranged on the outside of the drying chamber, a heat source gas main pipeline one and a heat source gas main pipeline two fixedly installed on both sides of the floor of the drying chamber, a plurality of heat source gas diversion pipelines fixedly installed on the heat source gas main pipeline one and the heat source gas main pipeline two, a plurality of heat source gas electronic nozzles evenly installed on the heat source gas diversion pipelines, and a suspension installation rope fixedly installed on the inner wall of the top side of the drying chamber, with a sensor assembly fixedly installed at the bottom end of the suspension installation rope.

[0006] Preferably, two floor material racks are arranged on the floor of the drying room, with the floor material racks 20 centimeters above the ground.

[0007] Preferably, electronic exhaust fans are installed on both sides of the drying room to remove moisture.

[0008] Preferably, the first and second main heat source gas pipelines alternately serve as heat source gas branch pipelines to transport hot gas, with one branch pipeline every 8 meters and one electronic nozzle for heat source gas every 0.5 meters on each branch pipeline.

[0009] Preferably, the sensor assembly includes a temperature sensor and a humidity sensor.

[0010] Preferably, the electronic exhaust fan, sensor assembly, heat source gas diversion pipe, and control box are all equipped with wireless network modules. The control box is also equipped with an interaction module, a data processing module, and a decision module. The wireless network module is used to transmit data between the electronic exhaust fan, sensor assembly, heat source gas diversion pipe, and control box. The interaction module is used by maintenance personnel to connect to the control box. The decision module is used to control the various components in the drying room.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model utilizes a drying chamber to store activated carbon, and uses a heat source gas diversion pipe to spray the gas with residual heat generated by the roller kiln onto the activated carbon product. The activated carbon product is slowly dried using the gas with residual heat. Compared with the drying time of the roller kiln, it has a longer drying time but lower cost and can consume the waste heat resources generated by the roller kiln.

[0013] 2. This utility model utilizes sensor components to detect temperature and humidity information at various points inside the drying chamber, and coordinates with the control box to regulate the hot gas delivery rate of the electronic nozzles for the heat source gas, thereby ensuring that the temperature remains consistent throughout the drying chamber. By using an electronic exhaust fan on the side of the drying chamber to discharge moisture, the device can stably dry activated carbon products. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A waste heat recovery system for a roller kiln includes a drying chamber 100. A control box 200 is arranged on the outside of the drying chamber 100. A first heat source gas main pipeline 300 and a second heat source gas main pipeline 301 are fixedly installed on both sides of the ground of the drying chamber 100. Several heat source gas diversion pipelines 302 are fixedly installed on the first heat source gas main pipeline 300 and the second heat source gas main pipeline 301. Several heat source gas electronic nozzles 303 are installed at equal intervals on the heat source gas diversion pipelines 302. A suspension installation rope 500 is fixedly installed on the inner wall of the top side of the drying chamber 100. A sensor assembly 501 is fixedly installed at the bottom end of the suspension installation rope 500. The system uses the drying chamber to collect activated carbon. The waste heat gas generated by the roller kiln is sprayed onto the activated carbon product through the heat source gas diversion pipelines. The activated carbon product is slowly dried using the waste heat gas. Compared with the drying time of the roller kiln, the system has a longer drying time but lower cost and can consume the waste heat resources generated by the roller kiln.

[0020] Two floor material racks 400 are arranged on the floor of the drying room 100, with the floor material racks 400 20 cm above the ground. Activated carbon products are placed on the floor material racks 400 for use. The floor material racks 400 isolate the activated carbon products from the ground, preventing moisture from being absorbed by the activated carbon products through contact with the ground and affecting the drying effect.

[0021] Electronic exhaust fans 101 are arranged on both sides of the drying chamber 100 to remove moisture. Based on the principle that hot air rises and cooler air falls, the cooler air will be discharged through the electronic exhaust fans 101, thereby ensuring that the internal temperature of the drying chamber 100 is stable.

[0022] The main heat source gas pipeline 300 and the second main heat source gas pipeline 301 alternately supply hot gas to the heat source gas distribution pipeline 302. Each heat source gas distribution pipeline 302 has one 8-meter section, and each has a heat source gas electronic nozzle 303 installed every 0.5 meters. The control box 200 activates the main heat source gas pipelines 300 and 301 to supply hot gas to the heat source gas distribution pipelines 302. The hot gas is then evenly sprayed inside the device through the heat source gas electronic nozzles 303, maintaining the temperature inside the drying chamber 100 within the range of 70 to 80 degrees Celsius.

[0023] The sensor assembly 501 includes a temperature sensor and a humidity sensor. The sensor assembly 501 monitors the temperature and humidity at various points inside the drying chamber 100. When the temperature is lower than the standard drying temperature, the surrounding heat source gas electronic nozzles 303 are activated to deliver heat source gas to the location, thereby achieving drying at that location.

[0024] Wireless network modules are arranged on the electronic exhaust fan 101, sensor assembly 501, heat source gas diversion pipe 302, and control box 200. The control box 200 also contains an interaction module, a data processing module, and a decision module. The wireless network module is used to transmit data between the electronic exhaust fan 101, sensor assembly 501, heat source gas diversion pipe 302, and control box 200. The interaction module is used by maintenance personnel to connect to the control box 200. The decision module is used to control the various components in the drying room 100.

[0025] Working principle:

[0026] When using this device, the activated carbon product needs to be placed on the ground material rack 400. The ground material rack 400 isolates the activated carbon product from the ground, preventing moisture from being absorbed by the activated carbon product through ground contact and affecting the drying effect. The control box 200 starts the main heat source gas pipeline 300 and the main heat source gas pipeline 301 to supply heat source gas to the heat source gas distribution pipeline 302. The heat source gas is then evenly sprayed inside the device through the heat source gas electronic nozzle 303, keeping the temperature inside the drying chamber 100 within the range of 70 to 80 degrees Celsius. At the same time, based on the principle that hot air rises and air falls, the cooler air will be discharged through the electronic exhaust fan 101, thereby ensuring the temperature inside the drying chamber 100 is stable. The sensor component 501 monitors the temperature and humidity at various points inside the drying chamber 100. When the temperature is lower than the standard drying temperature, the surrounding heat source gas electronic nozzles 303 are activated to deliver heat source gas, achieving drying at that location.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
