Figure 2 It is a cross-sectional schematic diagram of a waste gas purification and environmental protection equipment for a thermal power plant according to the first embodiment of the utility model.

[0021] The utility model provides a waste gas purification and environmental protection equipment for a thermal power plant: comprising a box body 101 and a purification component 102, wherein the purification component 102 further comprises a fan 103, an air inlet pipe 104, a slot 105, a filter plate 106, a connecting pipe 107, a nozzle 108, a water inlet mechanism 109, a water tank 110, a water pump 111, a water pipe 112, a water inlet pipe 113, a pipe cover 114, a water outlet pipe 115, a control valve 116 and a protective cover 117. The above-mentioned solution solves the problem that impurities such as dust and sulfur in the flue gas are easily attached to the inner side of the device and easily affect the device during actual use.

[0022] In this embodiment, the box body 101 is used to collect flue gas during purification.

[0023] The air inlet pipe 104 is connected to the box 101 and is located on one side of the box 101. The fan 103 is connected to the box 101 and is located on a side of the box 101 away from the air inlet pipe 104. The slot 105 is fixedly connected to the box 101 and is located on the inner side of the box 101. The filter plate 106 is slidably connected to the slot 105 and is located on one side of the slot 105. The connecting pipe 107 is fixedly connected to the box 101 and is located on the inner side of the box 101. The nozzle 108 is connected to the connecting pipe 107 and is located on one side of the connecting pipe 107. The water inlet mechanism 109 is connected to the connecting pipe 107 and is located on the outer side of the box 101. The protective cover 117 is rotatably connected to the box 101 and is located on the top of the box 101. When the device is used, the fan 103 is started to allow smoke to flow out from the air inlet pipe 1 04 enters the inner side of the box body 101. A plurality of filter plates 106 are installed on the inner side of the box body 101. The large particles of impurities in the flue gas can be filtered out by the filter plates 106, and then the flue gas continues to move toward the fan 103. During the process, the water inlet mechanism 109 provides the connecting pipe 107 with a liquid medicine that can decompose or sink the sulfur element in the flue gas, which is sprayed by the nozzle 108 and combined with the flue gas to purify the harmful substances in the flue gas. The purified flue gas is discharged through the air outlet of the fan 103. The filter plate 106 is slidably installed on the inner side of the box body 101 through the slot 105, which is convenient for removal, replacement or cleaning. The protective cover 117 increases the air tightness of the top of the box body 101 and prevents the filter plate 106 from being arbitrarily extracted, thereby solving the problem that impurities such as dust and sulfur in the flue gas are easily attached to the inner side of the device during actual use of the existing equipment, which easily affects the normal use of the device.

[0024] Secondly, the water tank 110 is arranged on one side of the box body 101, the water pump 111 is connected to the water tank 110 and is located on one side of the water tank 110, the water pipe 112 is connected to the water pump 111 and to the connecting pipe 107, and is located between the water pump 111 and the connecting pipe 107. The water tank 110 is used to store water and mix medicines. The water in the water tank 110 is pumped out by the water pump 111, and then enters the connecting pipe 107 through the water pipe 112.

[0025] Again, the water inlet pipe 113 is connected to the water tank 110 and is located at the top of the water tank 110. The pipe cover 114 is threadedly connected to the water inlet pipe 113 and is located on the side of the water inlet pipe 113 away from the water tank 110. The water inlet pipe 113 is used to add water or medicine to the water tank 110, and the pipe cover 114 is used to seal the water inlet pipe 113.

[0026] Finally, the water outlet pipe 115 is connected to the box body 101 and is located on one side of the box body 101. The control valve 116 is connected to the water outlet pipe 115 and is located on one side of the water outlet pipe 115. The water outlet pipe 115 is used to discharge the water inside the box body 101. The opening and closing of the water outlet pipe 115 can be controlled by the control valve 116.

[0027] When using the waste gas purification and environmental protection equipment of a thermal power plant of the utility model, the box 101 is used to collect the flue gas during purification, and the fan 103 is started to allow the flue gas to enter the inner side of the box 101 from the air inlet pipe 104. A plurality of filter plates 106 are installed on the inner side of the box 101. The large particles of impurities in the flue gas can be filtered out by the filter plates 106, and then the flue gas continues to move toward the fan 103. During the process, the water inlet mechanism 109 provides the connecting pipe 107 with a liquid medicine that can decompose or sink the sulfur element in the flue gas. The nozzle 108 is sprayed and combined with the flue gas to purify the harmful substances in the flue gas. The purified flue gas is discharged through the air outlet of the fan 103. The filter plate 106 is slidably installed on the inner side of the box body 101 through the slot 105, which is convenient for removal, replacement or cleaning. The protective cover 117 increases the air tightness of the top of the box body 101 and prevents the filter plate 106 from being randomly extracted, thereby solving the problem that impurities such as dust and sulfur in the flue gas are easily attached to the inner side of the device during actual use of the existing equipment, which easily affects the normal use of the device.
