[0002] During the cement production process, a large amount of waste gas is generated, which contains a large amount of dust and harmful substances, causing serious impacts on the environment and human health. Therefore, it is very necessary to treat the waste gas in cement production.

[0003] In the existing waste gas treatment equipment, water mist purification is a common method. This method sprays water mist into the waste gas so that the dust and harmful substances in the waste gas are combined with the water mist to form larger particles, which are convenient for subsequent filtration and removal. However, the wastewater generated by water mist purification of waste gas contains a large amount of solid particles and harmful substances, which need to be filtered through a filter. During the regular replacement of the existing filter, the waste gas treatment equipment needs to be shut down, which will cause interruptions in the production process, affect production efficiency, and be unfavorable to sustainable development. It has brought many troubles to people. Therefore, based on the above shortcomings, an environmentally friendly waste gas treatment equipment in cement production is now introduced to improve this.

[0021] As a preferred solution, further, baffles are provided on both the left and right sides of the top of the inner cavity of the shell 1, and the baffles can prevent water mist from spraying toward the flue.

[0022] The electrical components mentioned in this solution are all existing technologies, and their models are only one of them. As long as the electrical components can meet the requirements of this solution, they can be used.

[0023] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control. The specific work is as follows.

[0024] When in use, the waste gas generated by cement production will enter the shell 1 through the flue, and the water pump 3 will be turned on. The water pump 3 will extract the clean water in the box body 2 and spray it inside the shell body 1 in the form of water mist. The waste gas in the shell body 1 will contact with the water mist, thereby achieving the purpose of dust reduction and neutralizing harmful substances in the waste gas. The neutralized sewage will flow through the drainage trough 11 to the filter screen 13 on one side. After being filtered by the filter screen 13, the water will flow downward and pass through the one-way valve 16 to flow into the box body 2 for recycling. When it is necessary to disassemble and replace the filter screen 13 in use, the staff can move the positioning rod 10 upward. When the positioning rod 10 is completely removed from the inner cavity of the positioning hole 9, the connecting seat 8 is rotated to cause the connecting rod 7 to drive the rotating drum 6 and the drainage trough 11 to rotate together, so as to adjust the position and direction of the drainage trough 11, so as to facilitate switching between the two filter screens 13. Turn the turntable 14 forcefully. When the turntable 14 is gradually rotated out of the shell 1, the filter screen 13 will be brought out of the inner cavity of the shell 1 together with the turntable 14, thereby completing the disassembly of the filter 13. During installation, it is only necessary to reinsert the filter 13 into its original position and rotate the turntable 14 to tighten it on the shell 1. The position of the filter 13 is fixed, thereby completing the installation of the filter 13, that is: when disassembling and replacing the filter 13 on one side, the position direction of the drain groove 11 is adjusted by rotating the drum 6, so that the filter 13 channel on one side is closed, while the filter 13 channel on the other side is opened. The staff can disassemble and replace the filter 13 with the closed channel in the above manner, and the filter 13 with the opened channel can meet the normal use of the equipment; the device adopts a double filter design, so that when one filter is disassembled and replaced, the entire equipment can operate normally without shutdown interruption, which greatly improves the overall production efficiency and is conducive to the continuous treatment of exhaust gas. It is simple and convenient to operate, flexible to use, and highly practical, meeting the use needs in the existing market.
