Description

Technical Field

[0001] The patent of this invention belongs to the field of environmental protection technology, and relates to a plasma filter circulation washing and wastewater treatment system with a reaction unit, which can be widely used in the washing of plasma equipment in the rock wool industry and the treatment of wastewater after washing, so as to realize the recycling of wastewater. Background Art

[0002] In recent years, environmental protection requirements have become increasingly stringent, and the rock wool industry has undergone a large-scale reshuffle. Rock wool companies that meet environmental protection equipment standards can produce normally, while companies that do not meet environmental protection equipment standards have basically been shut down for rectification or eliminated. Therefore, rock wool companies attach great importance to environmental protection requirements. Some rock wool companies have already deployed wastewater treatment equipment in advance to cope with the newly implemented Ten Water Regulations when environmental protection did not make mandatory requirements for wastewater in the rock wool industry.

[0003] Under increasingly stringent environmental protection policies, the rock wool industry has gradually achieved industrial upgrading. Most companies are equipped with plasma filter equipment to treat waste gas emitted during the production process to meet the latest environmental protection standards. The main components of waste gas emitted by the rock wool industry are phenolic resin particles, phenol, formaldehyde, etc. Since the phenolic resin in the waste gas has a high viscosity, it is difficult to clean after being captured by the plasma filter equipment, making it difficult to clean the equipment. In addition, the existing plasma filter cleaning uses clean water offline flushing, which causes the plasma filter to generate tens of tons of phenolic resin wastewater every day; in order to reduce water consumption, companies currently generally reuse part of the wastewater as water for rock wool production slurry to achieve water balance; but with the fluctuation of production, the amount of wastewater generated often exceeds the amount of slurry reused, resulting in the technical problem of having nowhere to discharge excess wastewater. Summary of the invention

[0004] Based on the needs of reality and production practice, the applicant has invested a large amount of money and, after long-term research, has provided a plasma filter circulating washing and wastewater treatment system with a reaction unit, which is used to clean the plasma filter for flue gas treatment in the rock wool industry and to treat the wastewater generated after cleaning. It can solve the problem of cleaning the plasma filter plates and pole wires, and the wastewater generated after cleaning can be recycled after treatment.

[0005] According to the first aspect of the technical solution of the patent of the present invention, a plasma filter circulating washing and wastewater treatment system with a reaction unit is provided, which includes a plasma filter circulating washing system and a wastewater treatment system.

The wastewater treatment system reacts and purifies the wastewater generated by the circulating washing system.

[0006] Among them, the control unit is the central control system of the entire system, which controls the start and shut down of the cleaning unit, reaction unit and filter press unit; the reaction unit includes two parts: storage and reaction of the reagent.

[0009] More preferably, the main work of the filter press unit is to transport the sludge precipitated in the reactor to the filter press through a plunger pump for filtration, so as to achieve separation of sludge and water.

[0010] More preferably, the sludge is transported away by bucket trucks, and the treated water flows by gravity to a clean water tank for storage and reuse.

[0011] Furthermore, the wastewater treatment system sends the wastewater containing high-concentration phenolic resin in the circulating washing tank to the reactor through the wastewater lifting pump, and at the same time, the developed water treatment agent is accurately added to the first-stage reaction of the reactor through a metering pump. The wastewater after the reaction enters the second-stage reaction of the reactor. The wastewater that completes the first and second-stage reactions is filtered through a filter press to achieve mud and water separation.

[0012] Furthermore, the reaction unit is used to treat the wastewater generated after cleaning the plasma filter, and the reaction unit includes a wastewater lifting pump C1, a reagent barrel C2 filled with phenolic resin decomposing agent, a unloading pump C3, a phenolic resin decomposing agent storage tank C4, a dosing pump C5, a pipeline mixer C6, a circulation pump C7, a first reactor C8, a solenoid valve C9, a reagent barrel C10 filled with phenolic resin coagulant, a unloading pump C11, a phenolic resin coagulant storage tank C12, a solenoid valve C13, a pipeline mixer C14 and a second reactor C15.

[0013] Furthermore, the reagent barrel C2 filled with phenolic resin analytical agent is connected to the suction inlet of the discharge pump C3 through a pipeline, and the phenolic resin analytical agent is transported to the phenolic resin analytical agent storage tank C4 for storage and standby use through the outlet pipeline of the discharge pump C3; the reagent barrel C10 filled with phenolic resin coagulant is connected to the suction inlet of the discharge pump C11 through a pipeline, and the phenolic resin coagulant is transported to the phenolic resin coagulant storage tank C12 for storage and standby use through the outlet pipeline of the discharge pump C11; when the wastewater treatment reaction system is used, the wastewater generated after washing the plasma filter stored in the circulating washing tank B8 is transported to the reactor section C8 through the suction inlet of the wastewater lifting pump C1 and the outlet pipeline of the wastewater lifting pump C1, and the circulating pump C7 is turned on, and the inlet of the circulating pump C7 draws the wastewater from one side of the reactor section C8, and sends it to the pipeline mixer C6 through the outlet pipeline of the circulating pump C7 and then enters the other side of the reactor section C8.

[0014] In addition, while the dosing pump C5 is turned on, the inlet of the dosing pump C5 sucks the phenolic resin decomposing agent out of the phenolic resin decomposing agent storage tank C4, and transports it to the drug inlet of the pipeline mixer C6 through the outlet pipe of the dosing pump C5, and the mixing of the wastewater and the phenolic resin decomposing agent is completed in the pipeline mixer C6, and the mixed wastewater enters the reactor section C8 until the reaction is complete, and then the dosing pump C5 and the circulation pump C7 are turned off; the solenoid valve C9 is turned on to allow the wastewater that has completed the primary reaction in the reactor section C8 to flow to the pipeline mixer C14 through the pipeline, and the solenoid valve C13 is turned on to release the phenolic resin coagulant from the phenolic resin coagulant storage tank C12 to flow to the drug inlet of the pipeline mixer C14, and the mixing reaction of the wastewater and the phenolic resin coagulant is completed in the pipeline mixer C14, and then the wastewater enters the reactor section C15 to further complete the secondary reaction.

[0028] The following will be combined with the drawings in the embodiments of the patent of the present invention to clearly and completely describe the technical solutions in the embodiments of the patent of the present invention. Obviously, the described embodiments are only part of the embodiments of the patent of the present invention, not all of them. Based on the embodiments in the patent of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the patent of the present invention.

[0029] This patent proposes a plasma filter circulation washing and wastewater treatment system with a reaction unit, which includes a plasma filter circulation washing system and a wastewater treatment system. The plasma filter circulation washing system realizes circulation washing and cleaning and the treatment and reuse of the wastewater after washing through a control unit, a cleaning unit, a reaction unit, and a filter press unit.

[0030] The control unit is the central control system of the entire system, which controls the start and shut down of other unit equipment; the cleaning unit includes four parts: storage, preparation, flushing and recovery of reagents. The main function of reagent storage is to transport the reagent barrel filled with phenolic resin cleaning agent to the phenolic resin cleaning agent storage tank through the No. 1 unloading pump for storage. The preparation of the reagent is to prepare the high-concentration phenolic resin cleaning agent into the required concentration through the dispensing system. The flushing of the reagent is to transport the prepared reagent to the upper section of the plasma conductivity device through the reagent circulation cleaning pump, and spray the reagent at a certain flow rate and pressure through the arranged nozzle to flush the plasma conductivity device. The recovery of the reagent is that after the washing reagent flushes the plasma conductivity device, the reagent passes through the upper plasma section of the plasma conductivity device from top to bottom and enters the lower conductivity section, converges to the bottom of the plasma conductivity device, and enters the reagent circulation cleaning pool through the bottom connecting pipe. The reagent entering the reagent circulation cleaning pool is then sent to the upper section of the plasma conductivity device through the reagent circulation cleaning pump to realize circulation flushing.

[0031] The cleaning unit completely changes the original washing method, changing the original washing with clean water to washing with detergent; changing the daily flushing to cleaning when the furnace is shut down according to the production situation; the flushing time is generally 10 minutes a day, and it is preferred to clean 24 hours a day when the furnace is shut down after 20 days of operation; the waste water after washing is directly overflowed into the circulation pool to enter the detergent circulation washing pool; the one-time washing with clean water is changed to detergent circulation washing. The cleaning unit includes a detergent configuration system, a detergent circulation pool, and a spray circulation washing system. The spray circulation washing system is set inside the plasma filter, and there are also auxiliary equipment such as continuous water supply, instruments, delivery pumps and valves. The cleaning unit completes the configuration of the agent through the agent configuration system, and the configured detergent is delivered to the detergent circulation pool through the discharge pump. The detergent in the detergent circulation pool is pumped to the spray circulation washing system through the washing pump, and the detergent is sprayed on the plasma filter plate and pole line through the nozzle. The waste water after washing flows to the bottom of the plasma filter through the pole plate wall and is discharged from the bottom drain pipe to the detergent circulation pool to achieve the purpose of circulation washing. As the circulation washing time increases, the concentration of phenolic resin in the detergent gradually increases, and it needs to be pumped to the wastewater treatment system for treatment before reuse.

[0032] The reaction unit includes two parts: storage and reaction of reagents. The main function of reagent storage is to transport the reagent barrels filled with phenolic resin analytical agent to the phenolic resin analytical agent storage tank for storage through the No. 2 unloading pump, and to transport the reagent barrels filled with phenolic resin coagulant to the phenolic resin coagulant storage tank for storage through the No. 3 unloading pump. In the reaction part, the wastewater containing high-concentration phenolic resin from the circulating washing is transported to the reactor through the wastewater lifting pump, and then the dosage, reaction time, reaction temperature and pressure of the phenolic resin analytical agent and phenolic resin coagulant are controlled by the control system, so that the water-soluble phenolic resin reacts and precipitates in the reactor to form sludge.

[0033] The main work of the filter press unit is to send the sludge precipitated from the reactor to the filter press through a plunger pump for filtration. This achieves the separation of sludge and water. The sludge is transported away by a bucket truck, and the treated water flows by gravity to the clean water tank for storage and reuse. This achieves zero wastewater discharge and reduces the environmental protection pressure on rock wool companies.

[0034] The wastewater treatment system in the circulating washing and wastewater treatment system of the plasma filter with reaction unit sends the wastewater containing high concentration of phenolic resin in the circulating washing tank to the reactor through the wastewater lifting pump, and at the same time, the developed water treatment agent is accurately added to the reactor for the first stage reaction through the metering pump. The wastewater after the reaction enters the reactor for the second stage reaction, and the wastewater after the first and second stage reactions is filtered by the filter press to achieve mud and water separation. The clean water enters the clean water tank through the pipeline for storage and standby. The dehydrated sludge enters the batching system. The wastewater treatment system of the circulating washing and wastewater treatment system of the plasma filter with reaction unit further includes a wastewater lifting pump, a reactor, a reagent storage tank, a filter press, a belt conveyor, a clean water tank, a sludge dewatering machine, a sludge removal bucket car, and is also equipped with a metering pump and a pH meter for quantitatively conveying water treatment agents and a liquid level monitoring system. The wastewater treatment system can make the plasma filter basically not generate wastewater during operation, but only generate a certain amount of washing wastewater when cleaning the plasma filter. Control the generation of wastewater from the source. The wastewater after washing can be reused in production after being treated by the wastewater treatment system, achieving zero wastewater discharge.

[0035] Combine the following Figure 1 , Figure 2 and Figure 3 The plasma filter circulation washing and wastewater treatment system with reaction unit is described in detail. The plasma filter circulation washing and wastewater treatment system with reaction unit is functionally divided into two parts: circulation washing system and wastewater treatment system. Compared with the separate washing and wastewater treatment in the prior art, the present invention creatively enables a unified coordination mechanism (i.e., control system), which not only reduces the equipment cost, but also reduces the working conflicts between equipments and improves the efficiency of coordinated utilization of water resources and the power and energy efficiency of equipments.

[0036] The circulating washing system in the circulating washing and wastewater treatment system of the plasma filter with reaction unit comprises a control unit, a cleaning unit, a reaction unit and a filter press unit; wherein the control unit and the cleaning unit constitute the circulating washing system, and the control unit, the reaction unit and the filter press unit constitute the wastewater treatment system.

[0037] The control unit is used to control the normal operation of the cleaning system and the reaction system. The control unit is encapsulated in a rectangular cabinet, and is connected to the pumps, valves, and instruments in the cleaning unit, the reaction unit, and the filter press unit through cables. It issues operating instructions to the cleaning unit, the reaction unit, and the filter press unit, and adjusts the operation of the plasma filter guide through the information fed back by the cleaning unit, the reaction unit, and the filter press unit;

[0038] like Figure 1The structural schematic diagram of the cleaning unit shown is used to clean the plasma filter, which includes a reagent barrel B1 filled with phenolic resin cleaning agent, a unloading pump B2, a phenolic resin cleaning agent storage tank B3, a dosing pump B4, an electric valve B5, a dispensing box B6, a discharge pump B7, a circulating washing tank B8, a washing pump B9, a cleaning nozzle B10 and a washing switching valve B11. The reagent barrel B1 filled with phenolic resin cleaning agent is connected to the reagent suction inlet of the discharge pump B2 through a pipeline, and the phenolic resin cleaning agent is transported to the phenolic resin cleaning agent storage tank B3 through the outlet pipeline of the discharge pump B2 for storage and standby use; when using the cleaning system, the electric valve B5 on the top of the dispensing box B6 is opened, and water is transported into the dispensing box B6 through the electric valve B5, and the electric valve B5 is closed after reaching the specified liquid level; the dosing pump B4 is turned on, and the phenolic resin cleaning agent stored in the phenolic resin cleaning agent storage tank B3 is transported to the suction inlet of the dosing pump B4 through a pipeline, and the outlet pipeline of the dosing pump B4 is connected to the bottom of the dispensing box B6, and the phenolic resin cleaning agent is added to the specified liquid level through the bottom pipeline of the dispensing box B6. The detergent preparation is completed; the prepared detergent is stored in the dispensing box B6, and enters the suction inlet of the discharge pump B7 through the bottom connecting pipe of the dispensing box B6, and the outlet of the discharge pump B7 is connected to the circulating washing tank B8 through a pipe; the detergent transported to the circulating washing tank B8 is sucked in by the washing pump B9, and the outlet of the washing pump B9 transports the detergent to the top of the plasma conductivity device tower through a pipe, and the detergent is sprayed into the plasma conductivity device through the cleaning nozzle B10 on the top of the tower. The detergent after the cleaning equipment flows down to the bottom of the plasma filter through the inside of the plasma conductivity device, enters the washing switching valve B11 through the bottom pipe, and flows into the circulating washing tank B8 to complete the circulation cleaning. The washing switching valve B11 is normally open when cleaning the plasma filter, and is closed after the cleaning work is completed.

[0039] Figure 2 The schematic diagram of the structure of the reaction unit and the filter press unit is shown. Figure 2The reaction unit shown is used to treat the wastewater generated after cleaning the plasma filter. The reaction unit includes a wastewater lifting pump C1, a reagent barrel C2 filled with phenolic resin decomposing agent, a discharge pump C3, a phenolic resin decomposing agent storage tank C4, a dosing pump C5, a pipeline mixer C6, a circulation pump C7, a first reactor C8, a solenoid valve C9, a reagent barrel C10 filled with phenolic resin coagulant, a discharge pump C11, a phenolic resin coagulant storage tank C12, a solenoid valve C13, a pipeline mixer C14 and a second reactor C15. The reagent barrel C2 filled with phenolic resin analytical agent is connected to the suction inlet of the discharge pump C3 through a pipeline, and the phenolic resin analytical agent is transported to the phenolic resin analytical agent storage tank C4 through the outlet pipeline of the discharge pump C3 for storage and standby use; the reagent barrel C10 filled with phenolic resin coagulant is connected to the suction inlet of the discharge pump C11 through a pipeline, and the phenolic resin coagulant is transported to the phenolic resin coagulant storage tank C12 for storage and standby use through the outlet pipeline of the discharge pump C11; when the wastewater treatment reaction system is used, the wastewater generated after washing the plasma filter stored in the circulating washing tank B8 is transported to the reactor section C8 through the suction inlet of the wastewater lifting pump C1 and the outlet pipeline of the wastewater lifting pump C1, and the circulating pump C7 is turned on. The inlet of the circulating pump C7 draws the wastewater out from one side of the reactor section C8, and sends it to the pipeline mixer C6 through the outlet pipeline of the circulating pump C7 and then enters the other side of the reactor section C8. At this time, the dosing pump C5 is turned on, and the inlet of the dosing pump C5 sucks the phenolic resin decomposing agent from the phenolic resin decomposing agent storage tank C4, and transports it to the inlet of the pipeline mixer C6 through the outlet pipeline of the dosing pump C5. The wastewater and the phenolic resin decomposing agent are mixed in the pipeline mixer C6, and the mixed wastewater enters the reactor section C8 until the reaction is complete, and the dosing pump C5 and the circulation pump C7 are turned off; the solenoid valve C9 is turned on to let the wastewater that has completed the primary reaction in the reactor section C8 flow to the pipeline mixer C14 through the pipeline, and the solenoid valve C13 is turned on to release the phenolic resin coagulant from the phenolic resin coagulant storage tank C12 to flow to the inlet of the pipeline mixer C14, and the mixing reaction of the wastewater and the phenolic resin coagulant is completed in the pipeline mixer C14, and then enters the reactor section C15 to further complete the secondary reaction. The above is the reaction process of the entire reaction unit. In addition, after the cleaning is completed, the wastewater containing high concentration of water-soluble phenolic resin enters the reactor section in the wastewater treatment system, and the phenolic resin decomposing agent is used to react to precipitate the water-soluble phenolic resin from the wastewater. The function of the phenolic resin decomposing agent is to parse the phenolic resin from the water-soluble state to generate water-insoluble phenolic resin sludge, thereby realizing the separation of water-soluble phenolic resin from wastewater. The main components of the phenolic resin decomposing agent are acid, surfactant and hydrophobic agent. The wastewater after the precipitated phenolic resin is passed through the solenoid valve C9 to the wastewater that completes the primary reaction in the reactor section C8 through the pipeline to the pipeline mixer C14.The mixing reaction of wastewater and phenolic resin coagulant is completed in pipeline mixer C14. The function of the phenolic resin coagulant is to make the small particles of phenolic resin precipitated by the reaction condense into agglomerates to form large particles of sludge to facilitate the removal of phenolic resin from wastewater. The main components of phenolic resin coagulant are flocculant and coagulant.

[0040] Figure 2 The filter press unit shown is used to complete the filtration of wastewater after primary and secondary reactions. The filter press unit includes a plunger pump D1, a filter press D2, a belt conveyor D3, a sludge removal bucket D4, and a clean water tank D5 for storing clean water. After completing the primary and secondary reactions, the wastewater stored in the second stage of the reactor C15 flows to the inlet of the plunger pump D1 through the bottom pipeline of the second stage of the reactor C15. The outlet of the plunger pump D1 is connected to the filter press D2 through a pipeline. After the wastewater enters the filter press D2 for filtration, clean water and sludge are produced. The sludge falls from the filter press D2 to the belt conveyor D3 under the filter press D2, and is conveyed to the sludge removal bucket D4 by the belt; the clean water flows by gravity through the pipeline to the clean water tank D5 for storage. The above is the filtration process of the entire filter press unit.

[0041] Furthermore, the circulating washing system cleans the plasma filter, and a phenolic resin cleaning agent is required to improve the cleaning efficiency. The cleaning cycle of the plasma filter is generally selected to be 10 minutes per day, and preferably the furnace is stopped for 24 hours of flushing after 20 days of continuous operation. At this time, the plasma filter is guaranteed to operate stably for a long time with a cycle of 20 days. The function of the phenolic resin cleaning agent is to clean the phenolic resin adhered to the plasma filter, and the main components are alkali, surfactant, and penetrant.

[0042] Furthermore, the cleaning method of the present invention, in a plasma filter circulation washing and wastewater treatment system with a reaction unit, starts with the cleaning of the plasma filter, firstly, the phenolic resin cleaning agent and detergent are prepared in a certain proportion in the circulation washing tank, and the circulation washing pump is turned on to establish circulation, and the circulation washing time is 24 hours. After the circulation cleaning of the plasma filter is completed, the circulation washing pump is turned off, and the washing wastewater generated enters the circulation washing tank. At this time, the wastewater contains a large amount of water-soluble phenolic resin and resin blocks that fall down due to washing. When it cannot be used further due to high solid content, it enters the wastewater treatment process. The wastewater containing high-concentration phenolic resin is pumped to the first stage of the reactor by the wastewater pump to add the phenolic resin analytical agent to react, so that the resin in the water changes from water-soluble to water-insoluble, precipitates from the water, and separates from the water. The separated wastewater enters the second stage of the reactor, and the phenolic resin analytical agent is added to react. The resin in the wastewater is separated more thoroughly. The wastewater after the reaction is sent to the filter press through a plunger pump for filtration. The clean water after filtration is collected in the clean water tank, and the sludge is reused as raw material for producing rock wool.

[0043] On this basis, the plasma filter with reaction unit circulation washing and wastewater treatment system is intensively integrated to manufacture an integrated treatment standard plasma filter. The plasma filter is unfolded from left to right, which is a control unit, a cleaning unit, a reaction unit, and a filter press unit. The integrated plasma filter has reserved external pipe ports (for example, inlet and outlet pipes, etc.). According to the specific conditions of different rock wool factories, the reserved external pipe ports or inlet and outlet pipes can be connected to the integrated treatment plasma filter to achieve standardized treatment of different rock wool factories.

[0044] Furthermore, the wastewater treatment system in the plasma filter circulation washing and wastewater treatment system with a reaction unit is designed in detail. Figure 3 yes Figure 1 The design schematic diagram of the wastewater treatment system in FIG. The wastewater treatment system includes a cleaning unit, a reaction unit and a filter press unit.

[0045] In the plasma filter circulation washing and wastewater treatment system with reaction units of the present invention, components of the same structure can be used in coordination or together, thus improving the equipment's work efficiency and utilization efficiency and reducing the overall cost of the system.

[0046] The cleaning unit in the wastewater treatment system also includes a reagent barrel B1 filled with phenolic resin cleaning agent, a discharge pump B2, a phenolic resin cleaning agent storage tank B3, a dosing pump B4, an electric valve B5, a dispensing box B6, a discharge pump B7, a circulating washing tank B8, a washing pump B9, a cleaning nozzle B10 and a washing switching valve B11, and their connection relationship is as follows: Figure 1 The reaction unit in the wastewater treatment system also includes a wastewater lifting pump C1, a reagent barrel filled with phenolic resin decomposing agent C2, a discharge pump C3, a phenolic resin decomposing agent storage tank C4, a dosing pump C5, a pipeline mixer C6, a circulation pump C7, a reactor section C8, a solenoid valve C9, a reagent barrel filled with phenolic resin coagulant C10, a discharge pump C11, a phenolic resin coagulant storage tank C12, a solenoid valve C13, a pipeline mixer C14 and a reactor section C15, and the connection relationship thereof is shown as follows. Figure 2 The filter press unit in the wastewater treatment system includes a plunger pump D1, a filter press D2, a belt conveyor D3, a sludge removal bucket D4 and a clean water tank D5, and their connection relationship is as shown in FIG. Figure 2 shown.

[0047] The same structure is not repeated here. Figure 3The design diagram of the wastewater treatment system only shows the main design diagram, which is unfolded from left to right. The reagent barrel B1 filled with phenolic resin cleaning agent is connected to the reagent suction of the discharge pump B2 through a pipeline to enter the cleaning unit B to complete the preparation of the phenolic resin cleaning agent. After the preparation of the phenolic resin cleaning agent is completed, it is sent to the plasma conductivity device equipment through the washing pump B9 to clean the equipment and complete the cleaning work. The wastewater generated after cleaning the plasma conductivity device is sent to the reaction unit C for reaction through the wastewater lifting pump C1. In this process, phenolic resin decomposing agent and phenolic resin coagulant agent are added to react to form large-particle sludge to facilitate the removal of phenolic resin from the wastewater. It is sent to the filter press unit D for filtration through the plunger pump D1. After filtration, the clean water is collected in the clean water tank, and the sludge is reused as raw material for producing rock wool.
