Example Embodiment

[0039] Example 1

[0040] like figure 1 , figure 2 , image 3 and Figure 4 As shown in the figure, a thermal power plant denitration wastewater treatment device includes a rectangular base 1 that is fixedly arranged on the ground and formed by group welding of section steel, a cyclone that is fixedly connected to the base 1 by bolts in sequence from left to right, Vertical cylindrical closed sedimentation tank and rectangular closed filter box.

[0041] The upper part of the sedimentation tank is a semi-ellipsoidal head 20 , and the lower part of the sedimentation tank is a barrel-shaped tank body 18 . The tank body 18 and the head 20 are fixedly connected by flanges. The inlet pipe 7 is welded on the top left part of the sealing head 20, the dosing pipe 8 is welded on the top right part of the sealing head 20, and the dosing pipe 8 is provided with a valve. The bottom of the tank 18 is provided with an outlet pipe 16 .

[0042] The filter box includes a rectangular b...

Example Embodiment

[0052] Example 2

[0053] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is:

[0054] The upper part of the sedimentation tank is provided with a first cavity 25 and a second cavity 24 which are independent and closed from each other, the first cavity 25 is located above the second cavity 24, and the first cavity 25 is connected to the inlet pipe 7 The second cavity 24 communicates with the dosing pipe 8 , the bottom of the first cavity 25 is provided with a first downward nozzle, and the bottom of the second cavity 24 is provided with a second downward nozzle.

[0055] The bottom surface of the head 20 is welded with a bottom plate 21 , a partition plate 26 welded with the head 20 is arranged above the bottom plate 21 , the first cavity 25 is located above the partition plate 26 , and the second cavity 24 Below the partition plate 26, the inlet pipe 7 is welded through the head 20, the baffle plate 26 and the head 20 are welded through the ...

Example Embodiment

[0057] Example 3

[0058] like Image 6 As shown, the difference between this embodiment and Embodiment 1 is:

[0059] The right side of the tank body 18 is provided with a circulation pipe, and the circulation pipe is provided with a circulation pump 27 .

[0060] After the circulating pump 27 is started, the waste water in the tank 18 is circulated up and down, so that the waste water and the flocculant added in the dosing pipe 8 are mixed and reacted.

[0061] Since the circulation pump 27 and the circulation pipe are arranged outside the tank body 18, the maintenance can be easily performed when the circulation pump 27 fails.

Abstract

The invention discloses a thermal power plant denitration wastewater treatment device which comprises a base, a cyclone separator, a settling tank and a filter box, the cyclone separator, the settling tank and the filter box are sequentially and fixedly arranged on the base, an inlet pipe is arranged on one side of the top of the settling tank, a dosing pipe is arranged on the other side of the top of the settling tank, and an outlet pipe is arranged at the bottom of the settling tank; a transverse filter plate is detachably connected to the upper part in the filter box, and a main liquid outlet is formed in the bottom of the filter box; a top flow pipe of the cyclone separator is communicated with the inlet pipe, a second connecting pipe is arranged at the top of the settling tank and the top of the filter box, one end of the second connecting pipe is connected with the outlet pipe, and the other end of the second connecting pipe is communicated with the top of the filter box. The waste water generated after denitration of the thermal power plant is subjected to stage treatment, particulate matters and suspended matters in the waste water are sequentially separated, and the waste water treatment is more thorough.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a thermal power plant denitration wastewater treatment device. Background technique [0002] Thermal power denitrification refers to the denitration treatment of coal in thermal power generation in order to prevent excessive NOx pollution from the combustion of coal in the boiler. [0003] It is divided into pre-combustion denitration, combustion process denitration, and post-combustion denitration. That is to remove NOx (nitrogen oxides) in the flue gas. This substance enters the atmosphere to form acid rain. Acid rain is very harmful to human beings. Therefore, the country has been advocating environmental protection. Coal-fueled flue gas contains these substances. , especially thermal power plants. [0004] The denitrification of thermal power plants will produce waste water, and the content of suspended solids in the waste water is relatively large, a...
