Abstract
Description
Technical Field
[0001] This utility model relates to the field of power plant desulfurization technology, and in particular to a desulfurization wastewater treatment device for coal-fired power plants. Background Technology
[0002] During the daily production process of coal-fired power plants, a large amount of sulfur-containing liquid is generated. Direct discharge of this liquid will cause serious damage to the ecological environment. Therefore, a series of treatments are required to ensure that the sulfur meets the emission standards.
[0003] The authorized patent application with application number 202023047634.2 includes a processing tank, a motor, a handle, and a heating element. The top of the processing tank is provided with a liquid inlet. The bottom of the motor is rotatably connected to a motor shaft. The motor shaft has a first cavity inside. The connecting shaft has a second cavity inside. The side of the connecting shaft is connected to one end of a connecting rod. A receiving plate is fixed inside the processing tank below the cleaning brush. A movable plate is movably installed inside the receiving plate. A stirring shaft is fixed at the lower end of the motor shaft, and a scraper is movably installed at the bottom of the motor shaft. A partition plate is fixed inside the processing tank below the scraper. The heating element is installed on the inner bottom surface of the processing tank.
[0004] The problem with the aforementioned comparative documents is that they lack the function of quantitatively adding softener. Adding too much softener will directly lead to waste of softener, while adding too little softener will directly affect the treatment effect. Therefore, a desulfurization wastewater treatment device for coal-fired power plants is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a desulfurization wastewater treatment device for coal-fired power plants to solve the problems mentioned in the background art.
[0006] The technical solution adopted in this utility model is:
[0007] A desulfurization wastewater treatment device for a coal-fired power plant, comprising:
[0008] The equipment body is equipped with a feeding pipe; and
[0009] The plasticizer feeding assembly is installed on the upper part of the equipment body;
[0010] The softener feeding assembly includes:
[0011] Support platform, installed on the upper part of the equipment body;
[0012] The measuring cylinder is mounted on the upper part of the support platform;
[0013] A discharge pipe, the upper end of which passes through a support platform and is fixedly connected to the lower end of a measuring cylinder, and the other end of which is fixedly connected to a feeding pipe, and a water pump is installed on the discharge pipe; and

[0020] Optionally, the softener feeding assembly further includes:
[0021] L-shaped mounting bracket, fixed to the rear end of the support platform;
[0022] The controller is mounted on the upper part of the L-shaped mounting bracket;

[0031] Compared with the prior art, the beneficial effects of this utility model are:
[0032] When this type of desulfurization wastewater treatment equipment for coal-fired power plants is in use, the controller is first set to an extreme value based on the required amount of softener. The softener enters the measuring cylinder through the feed funnel. The pressure sensor collects the weight information of the softener in the measuring cylinder through the support column, support platform, and measuring cylinder, and transmits this information to the controller. The controller converts this information into data. When the data equals the extreme value, it indicates that the required amount of softener has been reached. The controller sends commands to the alarm and the switch valve. The alarm activates to remind the staff, and the switch valve closes to stop the softener in the feed funnel from entering the measuring cylinder. Finally, the water pump is started to guide the softener in the measuring cylinder into the main body of the equipment through the discharge pipe and feed pipe.
[0033] This invention has the function of quantitatively adding plasticizer, thereby solving the problems of plasticizer waste and affecting the treatment effect. Attached Figure Description

[0044] like Figure 1-4 As shown, this utility model embodiment provides a desulfurization wastewater treatment device for a coal-fired power plant, including a device body 1 and a softener feeding assembly 3. A feeding pipe 2 is installed on the device body 1, and the softener feeding assembly 3 is installed on the upper end of the device body 1.
[0045] The main body of the equipment 1 is the overall equipment in the authorized patent with application number: 202023047634.2. The feeding pipe 2 is also from the feeding pipe 2 in the authorized patent with application number: 202023047634.2. Both are existing technologies. The softener feeding component 3 can realize the quantitative addition of softener.
[0046] The softener feeding assembly 3 includes a support platform 310, a measuring cylinder 301, a discharge pipe 309, and a feed pipe 302. The support platform 310 is installed on the upper end of the equipment body 1, the measuring cylinder 301 is installed on the upper end of the support platform 310, the upper end of the discharge pipe 309 passes through the support platform 310 and is fixedly connected to the lower end of the measuring cylinder 301, the other end of the discharge pipe 309 is fixedly connected to the feeding pipe 2, a water pump 308 is installed on the discharge pipe 309, the feed pipe 302 is fixedly connected to the upper end of the measuring cylinder 301, and a switch valve 314 is installed on the feed pipe 302.
[0047] The softener can enter the measuring cylinder 301 through the feed pipe 302 and start the water pump 308. The water pump 308 works to guide the softener in the measuring cylinder 301 into the discharge pipe 309, and finally enter the equipment body 1 through the feed pipe 2.
[0048] In this embodiment, the softener feeding assembly 3 also includes a support column 306 and a support cylinder 305. The support column 306 is fixedly installed at the middle position of the lower end face of the support platform 310, and the support cylinder 305 is fitted into the bottom of the support column 306 and fixed to the upper end of the equipment body 1.
[0049] The softener feeding assembly 3 also includes a pressure sensor 307, which is fixedly installed at the bottom of the support cylinder 305. The upper end of the sensing end of the pressure sensor 307 is fixedly connected to the lower end of the support column 306, and the side end face of the support column 306 is slidably attached to the inner wall of the support cylinder 305.
[0050] The softener feeding assembly 3 also includes an L-shaped mounting bracket 311, a controller 312, and an alarm 313. The L-shaped mounting bracket 311 is fixed to the rear end of the support platform 310, the controller 312 is mounted on the upper end of the L-shaped mounting bracket 311, and the alarm 313 is fixed to the lower end of the L-shaped mounting bracket 311.
[0051] Pressure sensor 307 is electrically connected to controller 312, and controller 312 is electrically connected to alarm 313 and switching valve 314.
[0052] First, the controller 312 is set to an extreme value based on the required amount of softener. The controller 312 is a general-purpose SC200 controller. The pressure sensor 307 can collect the weight information of the softener in the measuring cylinder 301 through the support column 306, support platform 310 and measuring cylinder 301, and transmit this information to the controller 312. The controller 312 converts this information into data. When the data is equal to the extreme value, it means that the required amount of softener has been reached. The controller 312 sends instructions to the alarm 313 and the switch valve 314. The alarm 313 activates to remind the operator, and the switch valve 314 closes to stop the softener in the feed funnel 303 from continuing to enter the measuring cylinder 301.
[0053] The softener feeding assembly 3 also includes a feeding funnel 303, the lower end of which is inserted into the upper end of the feeding pipe 302.
