Description

Technical Field

[0001] The utility model relates to the technical field of boiler flue gas treatment, in particular to a boiler flue gas purification and treatment device. Background Technique

[0002] A boiler is an energy conversion device, and its core function is to convert the input energy (mainly the chemical energy and electrical energy in the fuel) into heat energy, and generate steam, high-temperature water or organic heat carriers by heating the working medium (usually water or other fluids); boiler flue gas refers to the gas emissions generated during the fuel combustion process of the boiler, which mainly includes carbon dioxide, water vapor, nitrogen oxides, sulfur oxides, particulate matter (dust), and other unburned hydrocarbons generated after fuel combustion. After heat exchange inside the boiler, these gases and particulate matter are discharged into the atmosphere through the chimney.

[0003] The patent document with the application number CN201420567444.9 discloses a boiler flue gas purification and treatment device, which includes a flue gas inlet, a reaction device inlet cone, a reaction device body, a connecting flue, and a dust collector. One end of the flue gas inlet is connected to the boiler flue gas outlet, the other end of the flue gas inlet is connected to the reaction device inlet cone, the reaction device inlet cone is connected to the reaction device body and is located below the reaction device body, the reaction device body is connected to the connecting flue, the connecting flue is connected to the dust collector, the dust collector is connected to the flue gas outlet, the structure of the reaction device body is a cuboid structure, and the reaction device inlet cone is a square conical structure. The utility model can reduce the link of the square-round diameter change of the flue, improve the distribution uniformity of the flue gas flow field, reduce the resistance of the flue gas flow, improve the operation reliability of the device, and ensure the deacidification efficiency of the flue gas. Based on the retrieval of the above patent and the combination of the existing boiler flue gas purification and treatment devices in the prior art, it is found that when the boiler flue gas purification and treatment device is applied, it mainly relies on the filtering components in the device to filter the flue gas. However, it is difficult to replace some of the filtering components in the device. After long-term use, the device will be blocked, which not only blocks the flue gas but also cannot effectively filter the harmful substances in the flue gas. In addition, the difficult-to-replace filtering components require a lot of time for the staff to disassemble and assemble, which is time-consuming and laborious. Content of the Utility Model

[0027] The filter chamber 202 is a space for placing filter elements. The support columns 204 are used to fix and support the entire purification mechanism 2. The motor chamber 205 is used to accommodate the drive motor 206, and the drive motor 206 is used to drive the movement of the barrier disc 207. Its beneficial effect is to achieve a rapid switching of the filtration path, thus simplifying the replacement process of the filter element. The barrier disc 207 is used to switch the filtration path of the flue gas, and its beneficial effect is that the replacement of the filter element can be realized without shutting down the machine, reducing the downtime. The first filter mesh chamber 208 and the second filter mesh chamber 209 are two filter mesh chambers that respectively accommodate the first filter cartridge 213 and the second filter cartridge 217, providing an installation position for the filter element and facilitating the replacement and maintenance of the filter element. The first filter cartridge 213 and the second filter cartridge 217 are places for installing the filter element. The filter elements built in the first filter cartridge 213 and the second filter cartridge 217 are the core components for purifying the flue gas, and its beneficial effect is that it can effectively remove harmful substances in the flue gas and protect the environment.

[0028] The working principle of the present utility model is as follows: The boiler flue gas purification and treatment equipment is additionally provided with a purification mechanism 2. Before using the boiler flue gas purification and treatment equipment, it is necessary to pre-connect the drive motor 206 to the power supply and connect it to the control terminal. It is also necessary to place filter elements, such as filter carbon, in multiple groups of the first filter cartridge 213 and the second filter cartridge 217. During the use process, the flue gas pipeline 1 is connected to the boiler, and the flue gas travels in the flue gas pipeline 1. When the flue gas passes through the purification mechanism 2, the flue gas needs to pass through multiple groups of the first filter cartridge 213 or the second filter cartridge 217 and be filtered by the filter carbon in the first filter cartridge 213 before being transmitted to the second docking gas pipe 203. During the use process, if it is necessary to replace the new filter element, the drive motor 206 is started to drive the barrier disc 207 to rotate. When the barrier disc 207 is rotated to the front of the first docking gas pipe 201, the first filter mesh chamber 208 is blocked, and the flue gas is filtered through the second filter mesh chamber 209. At this time, the staff opens the first cover door 212, and can clean the multiple groups of the first filter cartridge 213 inside the first filter mesh chamber 208 and replace the filter element in the first filter cartridge 213. On the contrary, when the drive motor 206 is started to drive the barrier disc 207 to rotate and the barrier disc 207 is rotated to the rear of the first docking gas pipe 201, the second filter mesh chamber 209 is blocked, and the flue gas is filtered through the first filter mesh chamber 208. At this time, the staff opens the second cover door 216, and can clean the multiple groups of the second filter cartridge 217 inside the second filter mesh chamber 209 and replace the filter element in the second filter cartridge 217. To sum up, the purification mechanism 2 adopts a double portable plug-in structure and a smoke control structure, which can quickly perform the replacement or cleaning operation of the filter element. And when used in conjunction with the smoke control structure, the filter element can be disassembled under the premise of interrupting the flue gas filtration operation while the purification mechanism 2 is normally filtering the flue gas, which is very convenient.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
