[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] Reference below Figure 1 The wastewater treatment equipment according to the embodiment of the utility model is described.

[0027] like Figure 1 As shown, the wastewater treatment equipment of the embodiment of the utility model includes a treatment container 1, and the interior of the treatment container 1 has a plurality of treatment units 11 arranged in sequence, and the treatment unit 11 includes an air chamber 111, an evaporation chamber 112, a liquid collecting chamber 113 and a condensate pipe 114, and the plurality of condensate pipes 114 all penetrate the evaporation chamber 112 and are connected between the air chamber 111 and the liquid collecting chamber 113, and the evaporation chamber 112 is provided with a wastewater inlet 115, a steam outlet 116 and a wastewater outlet 117, and the wastewater in the evaporation chamber 112 can exchange heat with the gaseous medium in the condensate pipe 114, and along the arrangement direction of the plurality of treatment units 11, the air chamber 111 of the first treatment unit 11 is provided with an air inlet 118, and the air inlet 118 is arranged on the wall surface of the treatment container 1, and the steam outlet 116 of the previous treatment unit 11 is connected with the air chamber 111 of the next treatment unit 11.

[0028] Specifically, Figure 1 As shown, the processing container 1 is preferably a tank body extending in the left-right direction.

[0029] The processing container 1 has a plurality of processing units 11 arranged in sequence from left to right. The processing unit 11 includes a gas chamber 111, an evaporation chamber 112, a liquid collecting chamber 113 and a condensation pipe 114. Preferably, the processing container 1 has a plurality of vertically arranged partitions, the outer peripheral surface of the partition is connected to the inner peripheral surface of the processing container 1, so as to divide the internal space of the processing container 1 into the gas chambers 111 and the evaporation chambers 112 arranged one by one. The partition at the right end of the evaporation chamber 112 is provided with a steam outlet. The steam outlet 116 and the cover body, the steam outlet 116 is arranged at the top of the partition at the right end of the evaporation chamber 112, so as to connect the evaporation chamber 112 at the left end of the partition and the air chamber 111 at the right end of the partition, so that the evaporation chamber 112 of the previous processing unit 11 along the direction from left to right is connected with the air chamber 111 of the next processing unit 11 through the steam outlet 116, the cover body is arranged at the bottom of the partition at the right end of the evaporation chamber 112, and connects the right wall surface of the partition and the inner peripheral surface of the processing container 1 to form a liquid collecting chamber 113.

[0030] There are multiple condensation tubes 114 in the processing unit 11, and the multiple condensation tubes 114 all extend in the left-right direction and penetrate the evaporation chamber 112, and the multiple condensation tubes 114 are connected between the gas chamber 111 and the liquid collecting chamber 113. Preferably, the multiple condensation tubes 114 are located in the lower half of the space of the evaporation chamber 112, the left end of the condensation tube 114 is connected to the partition at the left end of the evaporation chamber 112, and the left end of the condensation tube 114 is connected to the gas chamber 111, the right end of the condensation tube 114 is connected to the partition at the right end of the evaporation chamber 112, and the right end of the condensation tube 114 is connected to the liquid collecting chamber 113, so that the gaseous medium in the gas chamber 111 enters the liquid collecting chamber 113 through the multiple condensation tubes 114.

[0031] A wastewater inlet 115 is provided at the top of the evaporation chamber 112, and a wastewater outlet 117 is provided at the bottom of the evaporation chamber 112. Both the wastewater inlet 115 and the wastewater outlet 117 are provided on the wall of the processing unit 11. Wastewater enters the evaporation chamber 112 through the wastewater inlet 115, and then exchanges heat with the gaseous medium in the multiple condensation pipes 114. The wastewater absorbs the heat of the gaseous medium and generates steam. The steam rises to the top of the evaporation chamber 112 and enters the air chamber 111 of the next processing unit 11 through the steam outlet 116 to serve as the gaseous medium in the air chamber 111 of the next processing unit 11. The gaseous medium in the condensation pipe 114 absorbs cold and condenses to generate condensed water, which flows to the liquid collecting chamber 113 and is collected. The liquid collecting chamber 113 is preferably provided with an air outlet, which is provided on the wall of the processing container 1. The gaseous medium in the condensation pipe 114 after condensation also enters the liquid collecting chamber 113, and then is discharged from the processing container 1 through the air outlet.

[0032] In the direction from left to right, the air chamber 111 of the first processing unit 11 is provided with an air inlet 118, and the air inlet 118 is arranged on the wall of the processing container 1, so as to provide a gaseous medium with a certain temperature to the air chamber 111 of the first processing unit 11, and then condense in the multiple condensation pipes 114 of the first processing unit 11, and evaporate the wastewater in the evaporation chamber 112 of the first processing unit 11 to generate steam. The steam generated by the first processing unit 11 enters the air chamber 111 of the second processing unit 11, and then condenses in the multiple condensation pipes 114 of the second processing unit 11, and evaporates the wastewater in the evaporation chamber 112 of the second processing unit 11 to generate steam. The steam generated by the second processing unit 11 continues to enter the air chamber 111 of the next processing unit 11 until the last processing unit 11. The steam outlet 116 of the last processing unit 11 is arranged on the wall of the processing container 1, and the steam in the evaporation chamber 112 of the last processing unit 11 is discharged from the processing container 1 through the steam outlet 116.

[0033] Preferably, in the last processing unit 11, the steam in the air chamber 111 is condensed in multiple condensate pipes 114. Since the heat of the steam comes from the gaseous medium provided by the air inlet 118 and passes through the processing units 11 in sequence for heat exchange, the heat carried by the steam in the air chamber 111 of the last processing unit 11 is relatively low, and the wastewater in the evaporation chamber 112 evaporates to produce a small amount of steam, which is directly discharged into the atmosphere.

[0034] The wastewater is preferably industrial wastewater.

[0035] The wastewater treatment equipment of the embodiment of the utility model is provided with a plurality of sequentially arranged treatment units in the treatment container. In each treatment unit, the gaseous medium in the air chamber enters the liquid collecting chamber through a plurality of condensation pipes, and exchanges heat with the wastewater in the evaporation chamber when passing through the condensation pipes, so that the wastewater in the evaporation chamber evaporates, and condenses in the condensation pipes to produce condensed water, which is collected in the liquid collecting chamber. Along the arrangement direction of the plurality of treatment units, the air chamber of the first treatment unit is provided with an air inlet, through which the gaseous medium with heat is obtained, and the heat is transferred to the wastewater in the evaporation chamber, so that the wastewater evaporates, and the steam in the evaporation chamber of the previous treatment unit carries the heat into the air chamber of the next treatment unit, transfers the heat to the wastewater in the evaporation chamber of the next treatment unit and evaporates, and the steam from the previous treatment unit condenses in the condensation pipe of the next treatment unit. The energy of the wastewater treatment equipment comes from the heat of the gaseous medium obtained from the air inlet. The heat is transferred in turn in multiple processing units so that multiple processing units can treat wastewater at the same time. Therefore, the heat utilization rate is high and the energy consumption is low. At the same time, multiple processing units all treat wastewater, so the wastewater treatment equipment also has a high wastewater treatment efficiency.

[0036] In some embodiments, the air inlet 118 is used to connect to a steam supply device to obtain steam provided by the steam supply device, or the air inlet 118 is used to connect to an exhaust gas supply device to obtain exhaust gas provided by the exhaust gas supply device.

[0037] Specifically, the air inlet 118 can be connected to a steam supply device, and the steam generated by the steam supply device enters the air chamber of the first processing unit 11 through the air inlet 118, and then condenses through multiple condensate pipes 114. The steam supply device can be a steam pipe network of an industrial plant, which utilizes the waste heat of the steam pipe network through the first processing unit 11 and recovers the steam in the steam pipe network. The steam supply device can also be a storage device for storing wastewater. The wastewater in the storage device generates water vapor, which then enters the first processing unit 11 for utilization. At this time, the condensed water obtained by the first processing unit 11 also comes from the wastewater, further improving the treatment recovery rate of the wastewater.

[0038] The air inlet 118 can also be connected to the exhaust gas supply equipment, and the high-temperature exhaust gas generated by the exhaust gas supply equipment enters the air chamber of the first processing unit 11 through the air inlet 118, and then the water vapor in the high-temperature exhaust gas is condensed through multiple condensation pipes 114, so that the wastewater treatment equipment further realizes the treatment of the exhaust gas. Preferably, the exhaust gas supply equipment is an industrial equipment that discharges exhaust gas in an industrial plant.

[0039] In some embodiments, the wastewater treatment equipment of the utility model embodiment also includes a circulation pipe group 2. Along the arrangement direction of the multiple treatment units 11, the wastewater outlet 117 of the previous treatment unit 11 is connected to the wastewater inlet 115 of the next treatment unit 11 through the circulation pipe group 2, and / or the wastewater outlet 117 and the wastewater inlet 115 of each treatment unit 11 are connected through the circulation pipe group 2.

[0040] like Figure 1 As shown, along the direction from left to right, the wastewater outlet 117 of the previous treatment unit 11 is connected with the wastewater inlet 115 of the next treatment unit 11 through the circulation pipe group 2. After the wastewater in the evaporation chamber 112 of the previous treatment unit 11 is evaporated by heat exchange with the condensation pipe 114, it can enter the evaporation chamber 112 of the next treatment unit 11 through the circulation pipe group 2 for heat exchange and evaporation again, so that the wastewater can be evaporated in the evaporation chambers of multiple treatment units 11 in turn to generate steam, and condensed in the condensation pipe 114 of the next treatment unit 11 of the treatment unit 11 that generates steam, and the wastewater is processed multiple times in turn through the multiple treatment units 11.

[0041] At the same time, the wastewater outlet 117 of each treatment unit 11 is also connected to the wastewater inlet 115 through the circulation pipe group 2. After entering the evaporation chamber 112 of the treatment unit 11, the wastewater exchanges heat with the condensation pipe 114 for evaporation. The remaining wastewater is discharged from the wastewater inlet 115 and can repeatedly enter the evaporation chamber 112 through the circulation pipe group 2 to exchange heat with the condensation pipe 114 for evaporation again, so that the wastewater can circulate into the same evaporation chamber 112 and evaporate multiple times in the same evaporation chamber 112, so that each treatment unit 11 can circulate the wastewater.

[0042] In some embodiments, the circulation pipe set 2 includes a main pipe 21 , a branch pipe 22 , a circulation water pump 23 and a circulation valve 24 .

[0043] The main pipeline 21 is provided with a plurality of pipe openings, and the plurality of pipe openings are connected to the wastewater outlets 117 of the plurality of treatment units 11 in a one-to-one correspondence. The plurality of branch pipelines 22 are provided in a one-to-one correspondence with the plurality of treatment units 11, and each branch pipeline 22 is connected between the main pipeline 21 and the wastewater inlet 115 of the corresponding treatment unit 11. The circulating water pump 23 is provided on the main pipeline 21, and the plurality of circulating water pumps 23 are provided in a one-to-one correspondence with the plurality of pipe openings. The circulating valve 24 is provided on the main pipeline 21, and along the flow direction of the medium in the main pipeline 21, a corresponding circulating valve 24 is provided between the inlet end of the branch pipeline 22 connected to the previous treatment unit 11 and the pipe opening connected to the next treatment unit 11.

[0044] like Figure 1As shown, the main line 21 extends from left to right, and is provided with a plurality of pipe openings spaced apart along the left-right direction. The plurality of pipe openings are connected one-to-one with the wastewater outlets 117 of the plurality of treatment units 11, and the wastewater in the evaporation chamber 112 of each treatment unit 11 can enter the main line 21 through the corresponding pipe openings.

[0045] The main pipeline 21 is also provided with a plurality of branch pipelines 22 arranged at intervals along the left-right direction. The plurality of branch pipelines 22 are arranged one-to-one corresponding to the plurality of treatment units 11 . The inlet end of the branch pipeline 22 is connected to the main pipeline 21 , and the outlet end of the branch pipeline 22 is connected to the wastewater inlet 115 of the corresponding treatment unit 11 .

[0046] Along the direction of wastewater flow in the main pipeline 21, the pipe mouth connected to the same evaporation chamber 112 is arranged at intervals from the branch pipeline 22, and the pipe mouth is located upstream of the branch pipeline 22. The wastewater discharged from the evaporation chamber 112 of the treatment unit 11 can return to the evaporation chamber 112 through the branch pipeline 22 connected to the same evaporation chamber 112, and can also enter the evaporation chamber 112 of any other treatment unit 11 at the right end of the treatment unit 11 through other branch pipelines 22 downstream.

[0047] A plurality of circulating water pumps 23 are provided on the main pipeline 21, and the plurality of circulating water pumps 23 are arranged one-to-one correspondingly to the plurality of pipe outlets. A circulating water pump 23 is provided between the pipe outlet connecting each evaporation chamber 112 and the branch pipeline 22. The circulating water pump 23 is used to provide power so that the waste water in the evaporation chamber 112 connected to the corresponding pipe outlet can be discharged and flow in the main pipeline 21.

[0048] A circulation valve 24 is also provided on the main pipeline 21. Along the direction from left to right, a corresponding circulation valve 24 is provided between the inlet end of the branch pipeline 22 connected to the previous treatment unit 11 and the pipe mouth connected to the next treatment unit 11. The circulation valve 24 controls whether the wastewater in the main pipeline 21 continues to flow downstream of the main pipeline 21 through the circulation valve 24, or enters the corresponding evaporation chamber 112 through the branch pipeline 22 adjacent to the left end of the circulation valve 24.

[0049] When the amount of wastewater in the evaporation chamber 112 of any treatment unit 11 is large, the wastewater can be introduced into the evaporation chamber 112 of other treatment units 11 through the circulation pipe group 2. Therefore, the circulation pipe group 2 can also play a role in regulating the amount of wastewater in the evaporation chamber 112.

[0050] In some embodiments, the wastewater inlet 115 includes a first inlet 1151 and a second inlet 1152 . The first inlet 1151 is used to connect to a wastewater supply device to obtain wastewater provided by the wastewater supply device, and the second inlet 1152 is connected to the circulation pipe group 2 .

[0051] like Figure 1As shown, the wastewater inlet 115 includes a first inlet 1151 and a second inlet 1152. The first inlet 1151 and the second inlet 1152 are both arranged on the top wall of the treatment container 1. The first inlet 1151 is used to connect to the wastewater supply equipment to obtain the wastewater provided by the wastewater supply equipment. The wastewater supply equipment can be an industrial equipment that generates wastewater, or it can be a storage equipment that stores wastewater. The second inlet 1152 is connected to the outlet end of the corresponding branch pipe 22.

[0052] In some embodiments, the processing unit 11 further includes a spraying member 119 , which is disposed in the evaporation chamber 112 and above the plurality of condensation tubes 114 . The spraying member 119 is connected to the second inlet 1152 .

[0053] like Figure 1 As shown, the treatment unit 11 further includes a spraying member 119, which is disposed at the top of the evaporation chamber 112 and above the plurality of condensation pipes 114. The spraying member 119 is connected to the second inlet 1152. The wastewater supplied by the branch line 22 enters the spraying member 119 through the second inlet 1152, is sprayed into the evaporation chamber 112 through the spraying member 119, and is fully contacted with the plurality of condensation pipes 114 during the falling process, so that the wastewater fully exchanges heat with the plurality of condensation pipes 114 and fully evaporates to generate steam, thereby ensuring the treatment effect and heat exchange effect of the wastewater. The spraying member 119 is preferably a nozzle.

[0054] In some embodiments, the wastewater treatment equipment of the utility model embodiment further includes a spoiler 3 , which is disposed in the air chamber 111 of the first treatment unit 11 , and the spoiler 3 is disposed opposite to the air inlet 118 .

[0055] like Figure 1 As shown, from left to right, a spoiler 3 is provided in the air chamber 111 of the first treatment unit 11, and the spoiler 3 is arranged opposite to the air inlet 118. After the gaseous medium supplied by the air inlet 118 enters the air chamber 111, a turbulent flow is generated under the action of the spoiler 3, so that the gaseous medium is fully and evenly mixed and diffused in the air chamber 111, and then enters the multiple condensate pipes 114 evenly and at a uniform speed, with good flow field uniformity, thereby having high heat exchange efficiency and wastewater treatment effect.

[0056] It is understandable that the wastewater treatment equipment is not limited to having a baffle. In other embodiments, the air chamber of the first treatment unit does not have a baffle.

[0057] In some embodiments, the air inlet 118 is disposed at the bottom of the processing container 1 , the spoiler 3 extends horizontally and is tilted vertically, and the spoiler 3 is positioned vertically higher than the multiple condensate pipes 114 of the first processing unit 11 .

[0058] like Figure 1 As shown, the air inlet 118 is arranged at the bottom of the processing container 1 and extends in the vertical direction. The spoiler 3 is arranged in the upper half of the air chamber 111. The spoiler 3 extends from left to right and is inclined from top to bottom. The position of the spoiler 3 in the vertical direction is higher than the corresponding multiple condensate tubes 114. In other words, the right end of the spoiler 3 is connected to the corresponding partition. Among the multiple condensate tubes 114 connected to the partition, the highest condensate tube 114 is located below the right end of the spoiler 3 to ensure better flow field uniformity.

[0059] It is understandable that the air inlet is not limited to being located at the bottom of the processing container. In other embodiments, the air inlet is located at the top of the processing container and extends in the vertical direction, or the air inlet is located at the left end of the processing container and extends in the left-right direction.

[0060] In some embodiments, along the arrangement direction of the multiple processing units 11 and / or along the axial direction of the condensate tube 114, the length of the air chamber 111 of the first processing unit 11 is greater than the length of any air chamber 111 of the remaining processing units 11, and the difference between the length of the air chamber 111 of the first processing unit 11 and the length of any air chamber 111 of the remaining processing units 11 is 1100 mm to 1200 mm.

[0061] like Figure 1 As shown, the length of the air chamber 111 is the dimension of the air chamber 111 along the left-right direction. Among the air chambers 111 of the multiple processing units 11, the air chamber 111 of the first processing unit 11 connected to the air inlet 118 has the longest length. The difference between the length of the air chamber 111 of the first processing unit 11 and the length of any other air chamber 111 is 1100 mm to 1200 mm. In other words, the air chamber 111 of the first processing unit 11 is 1100 mm to 1200 mm longer than any other air chamber 111. The mixing time of the gaseous medium in the air chamber 111 is increased to improve the speed uniformity of the gaseous medium when entering the multiple condensate pipes 114.

[0062] The lengths of the other air chambers 111 may be the same or different, but are preferably the same, and more preferably 800 mm to 850 mm.

[0063] Preferably, the number of condensate tubes 114 included in the processing unit 11 is 2100 to 2250, and the diameter of the condensate tubes 114 is 20 mm to 30 mm, and more preferably 25 mm.

[0064] In some embodiments, the wastewater treatment equipment of the utility model embodiment also includes a liquid collecting pipe 4, a liquid collecting tank 5 and a liquid collecting water pump 6. The liquid collecting pipe 4 has multiple branches, and the multiple branches are connected one by one to the liquid collecting chambers 113 of multiple treatment units 11. Each branch is provided with a corresponding liquid collecting tank 5 and a corresponding liquid collecting water pump 6.

[0065] like Figure 1 As shown, the liquid collecting pipe 4 extends in the left-right direction, and has a plurality of branches arranged at intervals in the left-right direction. The plurality of branches are connected one-to-one with the liquid collecting chambers 113 of the plurality of processing units 11, and each branch is provided with a corresponding liquid collecting tank 5 and a corresponding liquid collecting water pump 6. The condensed water collected in the liquid collecting chamber 113 enters the corresponding liquid collecting tank 5 through the corresponding branch for storage. When the condensed water in the liquid collecting tank 5 needs to be discharged, the liquid collecting water pump 6 on the branch is turned on, and the condensed water in the liquid collecting tank 5 is pumped out by the liquid collecting water pump 6, and discharged to a designated position or designated equipment through the liquid collecting pipe 4.

[0067] In addition, the terms "first" and "second" are only used for distinction, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
