Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and particularly relates to a dosing device for a special powder agent for fluorescent wastewater. Background Art

[0002] The following several technologies are mainly adopted for fluorescent agent wastewater treatment equipment: physical adsorption method, chemical oxidation method, biodegradation method, etc. Among them, the physical adsorption method uses adsorbents with a high specific surface area, such as activated carbon, zeolite, etc., to adsorb and remove fluorescent substances in wastewater. This method has a low investment cost and good removal effect.

[0003] At present, a special powder agent for fluorescent wastewater, which is mainly composed of powdered activated carbon and mixed with other powder agents in a certain proportion, has appeared on the market, and it has a good treatment effect on fluorescent wastewater. However, there are also certain problems in the use process of the powder agent. On the one hand, dust is often generated during the addition process of the powder agent, which is not only a waste of the agent but also causes secondary pollution to the surrounding environment. On the other hand, the fluidity of the powder agent is poor, and manual intervention is often required during the dosing process, resulting in a low level of automation. Summary of the Invention

[0004] The purpose of the present invention is to provide a dosing device for a special powder agent for fluorescent wastewater to solve the problems of easy dust generation and low automation level during the dosing process of the powder agent in the prior art.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows: A dosing device for a special powder agent for fluorescent wastewater includes a chemical agent storage tank, a powder transfer pump, and a reaction integrated tank.

[0006] The chemical agent storage tank adopts a tray-type PP square ton barrel with a volume of 1000L. The powder agent is proportioned and filled into the chemical agent storage tank in the chemical agent supplier's factory building and then transported to the use site to avoid dust generation caused by configuring and filling the agent at the use site.

[0007] Four pulleys are fixed at the lower part of the ton barrel tray to facilitate the transfer of the ton barrel. Two of the pulleys on one narrow side are universal wheels for adjusting the forward direction, which is convenient for the transfer of the chemical agent storage tank in the limited space at the site.

[0008] An outlet is installed on one side of the bottom of the chemical agent storage tank, and a manual valve is installed outside the outlet to prevent the agent from spilling when the chemical agent storage tank is transported. A quick coupling is installed at the rear end of the manual valve to facilitate the disassembly and connection during the replacement of the chemical agent storage tank.

[0009] The barrel wall opposite to the outlet of the chemical agent storage tank is set to be inclined, and the angle between the barrel wall and the ground is greater than 50°. A variable-frequency vibration pump is fixed outside the barrel wall with bolts to ensure that the powder agent in the barrel can flow towards the outlet.

[0010] The powder transfer pump selects a pneumatic diaphragm type powder transfer pump. Compared with the conventional screw pump, the diaphragm pump has better sealing performance when transferring powder agents, and the powder flow stability is also more guaranteed.

[0011] In this solution, the reaction integrated tank is designed with a fully enclosed structure to prevent powder from escaping from the tank opening and causing dust.

[0012] The reaction integrated tank consists of chamber one, chamber two, chamber three and the reaction zone. Wastewater enters chamber one through the wastewater inlet, and the powder agent enters chamber one through the agent inlet. The agent inlet is buried under the liquid level, and then passes through chamber two, chamber three and the reaction zone in sequence to fully mix with the wastewater, reducing the amount of powder escaping into the air.

[0013] The partition lengths between chamber one, chamber two and chamber three are gradually shortened, gradually reducing the water flow resistance, and guiding the powder agent to move in the direction of chamber one, chamber two, chamber three and the reaction zone.

[0014] Atomizing spray heads are installed on the tops of chamber one, chamber two and chamber three. A small amount of powder agent escaping into the air combines with the water mist and falls back into the tank.

[0015] After the powder agent enters the reaction zone, fully mixes with the wastewater and adsorbs the characteristic pollution factors of the wastewater, polyaluminum chloride and polyacrylamide are added to the water to make the powder agent form a precipitate and finally separate from the treated clear water in the form of sludge.

[0019] The following is further described through specific embodiments:

[0020] The embodiment is basically as shown in the attached Figure 1 : A special powder agent dosing device for fluorescent wastewater, including a chemical agent storage tank 1, a powder transfer pump 2 and a reaction integrated tank 3.

[0021] The chemical agent storage tank 1 uses a tray type PP square ton barrel 1-1 with a volume of 1000L. The powder agent is proportioned and filled into the chemical agent storage tank in the chemical agent supplier's factory building and then transported to the use site, avoiding dust caused by configuring and filling the agent on site.

[0022] Four pulleys 1-3 are fixed at the lower part of the pallet of the ton barrel 1-1, which facilitates the transfer of the ton barrel. Two of the pulleys on one of the narrow sides are universal wheels for adjusting the forward direction, facilitating the transfer of the chemical agent storage tank 1 in the limited space on site.

[0023] A discharge port is installed on one side of the bottom of the chemical agent storage tank 1, and a manual valve 1-4 is installed outside the discharge port to prevent the chemical agent from spilling during the transfer of the chemical agent storage tank. A loose flange 1-5 is installed at the rear end of the manual valve to facilitate the disassembly and connection during the replacement of the chemical agent storage tank 1.

[0024] The barrel wall opposite to the discharge port of the chemical agent storage tank 1 is set to be inclined, and the angle between the barrel wall and the ground is greater than 50°. The variable-frequency vibration pump 1-2 is fixed to the outside of the barrel wall by bolts to ensure that the powdered chemical agent in the barrel can flow towards the discharge port. The vibration pump 1-2 is interlocked with the powder transfer pump 2. When the powder transfer pump 2 is started, the vibration pump 1-2 is started, and when the powder transfer pump 2 is shut down, the vibration pump 1-2 is shut down.

[0025] The powder transfer pump 2 is a pneumatic diaphragm type powder transfer pump. Compared with the conventional screw pump, the diaphragm pump has better sealing performance when transporting powdered chemical agents, and the powder flow stability is more guaranteed.

[0026] The main structure of the reaction integrated tank 3 is made of Q235 carbon steel plate by welding, and the outer dimensions of the tank body are L*B*H = 1.6m * 1.6m * 3.5m.

[0027] The inner wall of the reaction integrated tank 3 is divided into chamber one 3-1, chamber two 3-2, chamber three 3-3, and reaction zone 3-8 by partition one, partition two, and partition three. The height of partition one is 550mm, and the top is flush with the top of the tank body; the height of partition two is 500mm, and the top is flush with the top of the tank body; the height of partition three is 400mm, and the top is flush with the top of the tank body.

[0028] The top covers of chamber one 3-1, chamber two 3-2, and chamber three 3-3 are made of Q235 carbon steel plate, and the covers are fully welded to the top of the tank body to ensure sealing.

[0029] The bottom cover of the reaction zone 3-8 is made of PP plate, and the cover is fixed to the top of the tank body with glass glue, and the interface is ensured to be sealed, taking into account the convenience of later disassembly for internal maintenance.

[0030] The liquid level in the reaction integrated tank 3 is 200mm higher, and the pipeline of the chemical agent inlet 3-4 is buried 100mm below the liquid level in the tank. The lengths of the partitions between chamber one, chamber two, and chamber three in the tank are gradually shortened, gradually reducing the water flow resistance, and guiding the powdered chemical agent to move according to the flow direction of chamber one, chamber two, chamber three, and the reaction zone.

[0031] Atomizing spray heads 3-6 are installed above the top plates of Chamber 1 3-1, Chamber 2 3-2, and Chamber 3 3-3. The atomizing spray heads 3-6 are connected to the main tap water supply pipe through the spray nozzles. A spray solenoid valve 3-7 is installed on the main water supply pipe to automatically control the start and stop of the spraying. When the powder transfer pump 2 is turned on, the spray solenoid valve 3-7 is opened. When the powder transfer pump 2 is turned off, the spray solenoid valve 3-7 is closed with a 1-minute delay.

[0032] An exhaust port is provided on the top plate of Chamber 3. The diameter of the exhaust port is DN15 and is used to discharge the air that enters the reaction tank together with the powder agent.
