Description

Technical Field

[0001] This utility model relates to the field of high-performance oil well clinker production and application technology, and in particular to an ash recovery device for a preheating system for high-performance oil well clinker. Background Technology

[0002] Waste heat power generation refers to the technology of converting excess heat energy (such as waste gas, waste heat, and wastewater) generated during the production process of an external preheating kiln into electrical energy. This technology not only improves energy utilization efficiency but also reduces environmental pollution, making it an important means of achieving energy conservation and emission reduction in industry. Currently, the electrical energy converted from waste heat and waste gas in waste heat power generation systems can be returned to the production stage of high-performance oil well clinker for preheating materials. The waste heat power generation system requires the use of waste heat conveying pipelines to transport the hot air from the external preheating kiln system of the rotary kiln. However, the hot air generally carries dust, and because the conveying pipelines in the waste heat recovery system are relatively long, dust accumulates at the bottom of the pipelines. After a period of use, the dust accumulation affects the transport of hot air. The main current measure is to shut down the system and then inspect and clean the accumulated dust from the conveying pipelines. However, this cleaning method is not only cumbersome but also leads to reduced energy efficiency, increased production costs, and waste of recovered heat. Utility Model Content

[0003] The purpose of this application is to provide an ash recovery device for a high-performance oil well clinker preheating system, in order to solve the problems of traditional ash removal methods, which are not only cumbersome to operate but also lead to reduced energy efficiency, increased production costs, and waste of recovered heat.

[0004] To address the aforementioned technical problems, this application provides an ash recovery device for a high-performance oil well clinker preheating system, comprising:

[0005] A connecting pipe is installed at the bottom of the waste heat conveying pipeline. The lower end of the connecting pipe is connected to an ash discharge chute. An insert plate is installed on the upper side of the ash discharge chute through a connecting assembly. The lower end of the ash discharge chute is connected to an ash recovery pipe. One end of the ash recovery pipe is connected to an ash collection box. A negative pressure fan is connected to the side of the ash collection box away from the ash recovery pipe.

[0006] As a preferred embodiment, an ash recovery device for a high-performance oil well clinker preheating system is provided, wherein the insert plate is inclined downwards and positioned on the upper side of the ash discharge chute.

[0007] Further explanation is needed regarding the ash recovery device for a high-performance oil well clinker preheating system. The connecting assembly includes two side plates fixed to the opposite outer sides of the ash discharge chute. One end of the two side plates is jointly fixed with an mounting plate. A threaded rod is screwed onto the mounting plate, and the front end of the threaded rod is rotatably connected to one end of the insert plate. The side plates are parallel to the insert plate.

[0008] Further explanation is needed regarding the ash recovery device for a high-performance oil well clinker preheating system, wherein an operating handle is fixed to the rear end of the threaded rod.

[0009] As a preferred embodiment, an ash recovery device for a high-performance oil well clinker preheating system is provided, wherein one end of the ash recovery pipe is further provided with two branch recovery pipes, and one end of each of the two branch recovery pipes is connected to the ash collection box.

[0010] The solution requires further detailed explanation of an ash recovery device for a high-performance oil well clinker preheating system. The ash recovery pipe includes an ash recovery square pipe connected to the lower end of the ash discharge pipe and an ash recovery round pipe connected to one end of the ash recovery square pipe. One end of the two branch recovery pipes is connected to the ash recovery round pipe.

[0011] Compared with the prior art, the ash recovery device of the high-performance oil well clinker preheating system provided by this utility model includes a connecting pipe connected to the bottom of the waste heat conveying pipeline. The lower end of the connecting pipe is connected to an ash discharge chute. An insert plate is pulled out and installed on the upper side of the ash discharge chute through a connecting component. The lower end of the ash discharge chute is connected to an ash recovery pipe. One end of the ash recovery pipe is connected to an ash collection box. A negative pressure fan is connected to the side of the ash collection box away from the ash recovery pipe. During the process of conveying hot air through the waste heat conveying pipeline, the dust carried in the hot air will enter the ash discharge chute through the connecting pipe and temporarily settle at the insert plate. When it is necessary to clean the dust, the insert plate can be pulled out through the connecting component. During the process of pulling out the insert plate, the dust on it falls into the ash recovery pipe through the lower part of the ash discharge chute. After closing the insert plate with the help of the connecting component, the negative pressure fan can be started to recover the dust in the ash recovery pipe into the ash collection box. This device allows for the recovery of dust from the delivery pipeline without shutting down the preheating system. The operation is simple and convenient, improving energy efficiency, reducing energy consumption in the production of high-performance oil well clinker, lowering production costs, and avoiding the waste of recovered heat.
