Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of environmental functional materials, and particularly relates to a material production device for removing total phosphorus in a constructed wetland and a use method thereof. BACKGROUND

[0002] The constructed wetland is a unique plant and animal ecological system formed by planting water plants with good performance, high survival rate, strong water resistance, long growth cycle, beauty and economic value on the surface of the bed body while the sewage flows through the filler bed composed of a mixture of soil and fillers (such as gravel, zeolite, etc.) in a depression with a certain length-width ratio and bottom slope. The constructed wetland can remove nitrogen, phosphorus, suspended solids, organic matter, trace elements and pathogenic bacteria and other pollutants, and has the advantages of low construction and operation cost and easy maintenance.

[0003] In order to better remove total phosphorus in sewage in the constructed wetland, fillers are generally added in the constructed wetland. For example, the Chinese invention patent with the publication number CN107473387A discloses a constructed wetland phosphorus removal substrate filler and a preparation method thereof. The phosphorus removal filler is mainly made of wollastonite, fly ash, shale, gamma-aminopropyltrimethoxysilane, methyl acrylate monomer and diethylenetriamine. The phosphorus removal filler has the advantages of non-toxicity, high strength, light weight, strong adsorption performance, good stability, low production cost, strong pollutant removal capacity and good phosphorus removal effect.

[0004] In the preparation of the phosphorus removal filler, a constant temperature drying box is needed. However, the existing constant temperature drying box lacks a heat recovery mechanism, so that the hot air in the constant temperature drying box is easily discharged to the air. When other materials of the phosphorus removal filler need to be heated, the staff needs to reheat the constant temperature drying box, which not only easily reduces the production efficiency of the phosphorus removal filler, but also easily causes waste of heat energy resources, which does not meet the effect of environmental protection production.

[0059] Preferably, the drying box body 1 used in the present application is prior art, and the connection between the components is also prior art, so the connection and working principle will not be described in detail here.

[0060] Referring to Figures 1-12 The heat recovery mechanism 2 is installed on the side wall of the drying box body 1, and the heat recovery mechanism 2 is used to recover the heat energy resources in the drying cavity 101, so as to avoid waste of heat energy resources, and thus improve the environmental protection production effect of the phosphorus removal filler.

[0061] The heat recovery mechanism 2 comprises an air extraction pump 201, an air extraction pipe 202 and an exhaust pipe 203 connected to the air extraction pump 201, a gas collection cover 204 connected to one end of the air extraction pipe 202 in the drying cavity 101, and a heat recovery tank 205 connected to the exhaust pipe 203. When the air extraction pump 201 is running, the air extraction pump 201 extracts the gas with heat energy in the drying cavity 101 through the air extraction pipe 202 and the gas collection cover 204, and then delivers the gas to the heat recovery tank 205 through the exhaust pipe 203, so as to perform subsequent treatment on the gas with heat energy, including continuing to dry the other materials of the dephosphorization filler or heat exchange.

[0062] Preferably, the heat recovery tank 205 is provided with heat preservation materials on the outside, so as to avoid the loss of heat energy in the gas during storage or flow, thereby improving the utilization rate of heat energy resources.

[0063] In addition, the heat recovery tank 205 is provided with a heat storage cavity 206, a filtering cavity 207, a heat exchange cavity 208 and a recovery cavity 209.

If the drying tank main body 1 does not need to be used, the control valve 216 on the connecting pipe 1 211 connected to the heat exchange cavity 208 is opened.

[0066] In addition, the filtering cavity 207 and the heat exchange cavity 208 are connected by a connecting pipe 2 212, so that the filtering cavity 207 and the heat exchange cavity 208 can communicate with each other.

[0067] When it is needed to dry the other materials of the dephosphorization filler at a temperature lower than the previous temperature, the gas with heat energy can be made to enter the heat exchange cavity 208 from the filtering cavity 207 through the connecting pipe 2 212, and the heat exchange liquid 227 in the heat exchange cavity 208 is used to convert part of the heat of the gas, so that the temperature of the gas is lowered without waiting for the temperature of the gas to naturally decrease, thereby improving the production efficiency of the dephosphorization filler and facilitating the use of the staff.

[0068] Reference Figures 1-8As shown, the filter cavity 207 is connected with the backflow pipe 213 between the drying cavity 101, so that the gas with heat energy can backflow into the drying cavity 101, and then can heat the other materials of the dephosphorization filler in the drying cavity 101, improve the utilization rate of heat energy resources, and avoid waste of heat energy.

[0069] Preferably, the backflow pipe 213 is made of heat-conducting metal material, so that the heating wire 303 can heat the gas in the backflow pipe 213 when operating, and then the temperature of the gas can be increased, so that the staff needs to use higher temperature than the previous temperature to dry the other materials of the dephosphorization filler, so as to reduce the preheating time of the drying box main body 1, thereby improving the production efficiency of the dephosphorization filler.

[0070] Among them, the heat exchange cavity 208 is connected with the recovery cavity 209 through the connecting pipe three 214. When the drying box main body 1 is not needed to be used, the gas with heat energy can enter into the recovery liquid 217 through the connecting pipe three 214 to perform the last heat energy transfer, effectively avoiding the waste of heat energy resources.

[0071] In addition, the connecting pipe four 215 is connected between the backflow pipe 213 and the connecting pipe three 214, so that the gas with heat energy in the heat exchange cavity 208 can backflow into the drying cavity 101 through the backflow pipe 213, so that the heat energy in the gas can be reused.

[0077] The filtering mechanism comprises a pair of net racks 219, and a plurality of filtering balls 220 are arranged between the pair of net racks 219. The filtering balls 220 are used for filtering impurities in the hot-energy gas, so as to avoid the impurities from affecting other materials of the dephosphorization filler and ensure the production effect of the dephosphorization filler.

The filtering ball 220 moves irregularly between the pair of net racks 219 under the action of the hot-energy gas. When the filtering ball 220 contacts the net rack 219, the capillary holes on the surfaces of the outer membrane 2201 and the protective membrane 2203 are deformed by extrusion, so that the purification liquid 2202 can flow out through the capillary holes and contact the hot-energy gas, so as to wrap the impurities in the hot-energy gas and be filtered by a pair of filtering nets 221.

[0079] Preferably, the outer membrane 2201 is a water-insoluble membrane, the purification liquid 2202 is a gel liquid, the protective membrane 2203 is rubber, and has certain heat resistance and good elasticity.

[0080] Specifically, the lower side of the net rack 219 is provided with a pair of filtering nets 221. When the impurities wrapped by the purification liquid 2202 pass through the filtering nets 221, the impurities can be filtered, so as to further filter the hot-energy gas.

After drying is completed, the vacuum pump (201) is operated through the control panel (103). The vacuum pump (201) absorbs the gas with heat energy in the drying chamber (101) through the vacuum pipe (202) and the gas collecting hood (204), and transports the gas through the exhaust pipe (203) to the heat recovery box (205) for temporary storage; S3. If the staff needs to continue drying the dephosphorization filler and other materials at the same temperature, they first need to place the dephosphorization filler and other materials into the drying chamber (101), close the cover door (102), and then open the connecting pipe 1 (211) and the control valve (216) on the return pipe (213) connected to the filter chamber (207), so that the hot energy gas in the heat recovery box (205) enters the filter chamber (207) through the connecting pipe 1 (211), and the hot energy gas blows the filter ball (220) to move irregularly between the pair of grids (219). The filter ball (220) is moved irregularly to remove impurities in the gas. That is, when the filter ball (220) moves irregularly, the outer film (2201) and the protective film (2203) come into contact with the grid (219) and deform, so that the pore diameters of some capillaries on the side walls of the outer film (2201) and the protective film (2203) become larger. At this time, the purification liquid (2202) is discharged through the capillaries and comes into contact with the gas with thermal energy to remove impurities in the gas. When the gas with thermal energy flows back, the impurities in the gas are prevented from affecting the dephosphorization filler and other materials. S4, the gas from which impurities have been removed by the filter ball (220) is filtered again by a pair of filter screens (221), and finally flows back into the drying chamber (101) through the reflux pipe (213) to dry the dephosphorized filler and other materials in the drying chamber (101); S5. If the staff needs to dry the dephosphorization filler or other materials at a temperature higher than the previous temperature, the dephosphorization filler or other materials need to be placed in the drying chamber (101), the cover door (102) is closed, and then the connecting pipe (211) and the control valve (216) on the return pipe (213) communicating with the filter chamber (207) are opened, and the heating wire (303) is operated at the same time. The gas with heat energy passes through the filter ball (220) and the pair of filter screens (221) and is filtered, and then enters the return pipe (213). The heating wire (303) outside the return pipe (213) is used to heat the gas flowing in the return pipe (213), and a pair of temperature sensors (301) are used to detect the gas temperature before and after heating. S6. If the staff needs to dry the dephosphorized filler or other materials at a temperature lower than the previous temperature, the dephosphorized filler or other materials need to be placed in the drying chamber (101), the cover door (102) is closed, and then the control valve (216) on the connecting pipe 1 (211), the connecting pipe 2 (212) and the connecting pipe 4 (215) connected to the filter chamber (207) are opened, so that the hot gas passes through the filter ball (220) and a pair of filter screens (221) and is filtered, and then passes through the connecting pipe 2 (212) and the guide pipe. The pipe (223) enters the heat exchange tank (222), and the gas with heat energy transfers part of the heat to the heat exchange tank (222) through heat radiation, and uses the heat exchange fluid (227) to transfer the heat energy. The gas with heat energy is blown toward the blade (225) under the action of the guide pipe (223), so that the blade (225) rotates around the rotating shaft (224). The rotating rotating shaft (224) drives the stirring rod (226) to rotate, which is used to stir and mix the heat exchange fluid (227) to ensure that the heat exchange of the heat exchange fluid (227) is uniform. S7, the gas with heat energy will pass through the fin plate (228) for further heat energy transfer, and finally the cooled gas will flow to the return pipe (213) through the connecting pipe three (214) and the connecting pipe four (215), and enter the drying chamber (101); S8. If the staff does not need to use the drying box body (1), the control valve (216) on the connecting pipe 1 (211) and the connecting pipe 3 (214) connected to the heat exchange chamber (208) is opened, and the gas with heat energy enters the heat exchange tank (222) through the connecting pipe 1 (211) and the guide pipe (223), and transfers the heat energy to the heat exchange liquid (227) by thermal radiation, and is monitored by the temperature sensor 2 (229). If the heat exchange liquid (227) rises to a certain temperature, it is discharged through the water pipe (231) for subsequent use. The gas after heat exchange enters the recovery liquid (217) through the connecting pipe 3 (214) to transfer the remaining heat energy, and is finally discharged through the gas outlet hood (218).
