Description

Technical Field

[0001] This utility model relates to the field of boiler combustion technology, and in particular to a boiler auxiliary combustion aid device. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. It is mainly used for domestic purposes, and also has a small number of applications in industrial production. Boilers that produce steam are called steam boilers, often simply referred to as boilers. They are mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.

[0003] Currently, blowers are commonly used to assist combustion in boiler combustion. However, since the blowers introduce air into the combustion chamber, coal ash and dust are blown around, causing environmental pollution at the boiler inlet. In addition, the direction of the direct airflow can lead to incomplete combustion and partial ignition. To address these issues, we propose a boiler auxiliary combustion device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a boiler auxiliary combustion device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A boiler auxiliary combustion aid includes a boiler body with a cavity inside. A placement plate is fixed inside the cavity, and multiple ash collection holes are evenly spaced on the placement plate. An ash outlet is located at the lower end of the boiler body. Two semi-circular fixed pipes are fixed around the lower end of the boiler body. Multiple nozzles are evenly spaced around the circumference of each semi-circular fixed pipe. The nozzles on the two semi-circular fixed pipes are arranged crosswise, and the nozzles on the two semi-circular fixed pipes have different inclination angles, all corresponding to the lower end of the placement plate. One side of the boiler body... The device is equipped with a base, and a filter box is installed on the upper end of the base. A blower is installed on one side of the filter box. The air inlet of the blower is connected to a three-way pipe. One end of the three-way pipe is connected to a first air intake hood, and the other end of the three-way pipe is connected to a second air intake hood. Multiple filter plates are inserted into the filter box at equal intervals. An air outlet pipe is connected to one side of the filter box. A connecting pipe is connected to the lower end of the air outlet pipe. Air supply pipes are connected to both sides of the lower end of the connecting pipe. One end of each of the two air supply pipes is connected to one side of two semi-circular fixed pipes.

[0007] Preferably, the filter box has an opening at the top, a cover is hinged to one side of the upper end of the opening, a sealing layer is provided around the lower end of the cover, and the sealing layer corresponds to the circumference of the opening, and a handle is fixed to one side of the upper end of the cover.

[0008] Preferably, a feeding port is provided on one side of the lower end of the boiler body, and a furnace door cover is hinged to one side of the feeding port, with the furnace door cover corresponding to the placement plate.

[0009] Preferably, the semi-circular fixing pipe is fixed to the circumference of the boiler body using clamps.

[0010] Preferably, the gas pipeline is equipped with a valve.

[0011] Preferably, a handle is fixed to the upper end of the filter plate.

[0012] In this invention, when the boiler needs to be burned, coal blocks are placed on the placement plate, ignited, and the blower is started. When the blower draws in fresh air, it draws in fresh air through the first suction hood and absorbs the dust and flying debris generated by the airflow through the second suction hood. The dust and flying debris generated by the airflow are then sent into the filter box along with the air. After being purified by the filter plate, the air flows through the air outlet pipe to the connecting pipe, and then from the connecting pipe to the gas supply pipe. The gas is then sent into the semi-circular fixed pipe through the gas supply pipe and then sprayed out from the inclined nozzles. Both sets of nozzles are inclined, and their inclination angles are different. Therefore, the airflow can be more fully directed to different positions of the coal blocks at the top, promoting full and comprehensive combustion of the coal blocks at the top and reducing the generation of soot. When the filter plate needs to be replaced and cleaned, the cover is opened and the filter plate is removed.

[0013] The boiler auxiliary combustion device of this utility model can not only fully and comprehensively assist coal in multi-point combustion, but also reduce the pollution caused by flying debris and soot during combustion, thus playing a good role in protecting the environment around the boiler. It enhances the practicality and speed of combustion, protects the surrounding environment, and greatly improves the convenience for operators. Attached Figure Description
