Description

Technical Field

[0001] This utility model relates to the field of distillation equipment, and in particular to a distillation tower for wastewater treatment. Background Technology

[0002] Wastewater treatment requires the use of distillation columns. Currently, wastewater distillation columns have certain problems in use. For example, they lack a filtration structure for the influent. When treating wastewater, impurities that have not been completely removed are sent into the distillation column. These impurities accumulate on the distillation column's plates, easily causing scaling or clogging, thus affecting the distillation process. Furthermore, in traditional distillation columns, when the vapor pressure is too low, it is insufficient to prevent the liquid from flowing down through the perforations in the plates, leading to significant liquid leakage. Severe leakage can prevent heat transfer through the plates, disrupting the normal distillation process. Utility Model Content

[0003] The purpose of this invention is to provide a distillation tower for wastewater treatment, which has the advantages of being anti-clogging and leak-proof.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a distillation column for sewage treatment, comprising a column body, a sleeve provided on the surface of the column body, a sieve plate bolted inside the sleeve, quartz particles filled inside the sleeve, a water pump connected to the bottom of the sleeve via a pipe, the water pump being fixedly installed on the column body by a fixing component, a shelf plate bolted inside the column body, a sliding sleeve embedded in the top of the shelf plate, an exhaust sleeve slidably connected inside the sliding sleeve, an exhaust groove formed on the surface of the exhaust sleeve, and a sealing block fixedly fitted onto the surface of the exhaust sleeve.

[0005] By employing the above technical solution, this utility model incorporates quartz particles inside the sleeve. This allows wastewater to pass through the quartz particles, filtering out impurities and ensuring that only impurities are present in the gaps between them before being transported into the tower. This prevents impurities from affecting the subsequent distillation process. Furthermore, a shelf plate with a sliding sleeve is installed inside the tower. An exhaust sleeve is slidably connected to the inside of the sliding sleeve. When the gas pressure inside the tower is insufficient, the exhaust sleeve retracts into the sliding sleeve, sealing the exhaust groove. This, combined with a sealing block in contact with the sliding sleeve, improves the sealing performance and prevents leakage due to insufficient gas pressure.

[0006] The present invention is further configured such that: the top of the sleeve is connected to an inlet pipe, the output end of the water pump is connected to a drain pipe connected to the tower body, and valves are installed on the surface of both the inlet pipe and the drain pipe.

[0007] The above technical solution facilitates the addition of sewage to the sleeve and the entry of sewage into the tower body.

[0008] The present invention is further configured such that: the surface of the sleeve is connected to a backwash water pipe, the number of the backwash water pipes is two, and a valve is installed on the surface of the backwash water pipe.

[0009] The above technical solution facilitates backwashing inside the sleeve to remove impurities.

[0010] The present invention is further configured such that: a fixing seat is fixedly sleeved on the surface of the sleeve, and the fixing seat is bolted to the tower body.

[0011] The above technical solution is used to fix the sleeve.

[0012] The present invention is further configured such that: a support plate is bolted to the surface of the tower body, and the number of the support plates is two.

[0013] The above-mentioned technical solution is used to support the tower body.

[0014] The present invention is further configured such that: the top of the tower body is connected to an air outlet pipe, and the surface of the tower body is connected to an air inlet pipe.

[0015] The above technical solution facilitates air intake and exhaust inside the tower.

[0016] The present invention is further configured such that a liquid flow pipe is connected to the bottom of the tower body.

[0017] The above technical solution facilitates the discharge of wastewater after distillation.

[0018] The present invention is further configured such that a return spring is fitted on the surface of the exhaust sleeve.

[0019] The above technical solution provides a certain downward pressure to the exhaust sleeve.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model, by designing quartz particles inside the sleeve, allows wastewater to be filtered by the quartz particles when it enters the tower body. This filters out impurities in the wastewater and leaves them in the gaps between the quartz particles, ensuring that the wastewater is free of impurities before it enters the tower body. This prevents impurities in the wastewater from affecting the operation of the distillation tower during subsequent distillation.

[0022] 2. This utility model has a shelf installed inside the tower body, and a sliding sleeve installed on the shelf. An exhaust sleeve is slidably connected inside the sliding sleeve. When the gas phase pressure inside the tower body is insufficient, the exhaust sleeve retracts into the sliding sleeve to seal the exhaust groove. It works in conjunction with the sealing block to contact the sliding sleeve, thereby improving the sealing performance and preventing leakage caused by insufficient gas phase pressure.

A water pump 5 is connected to the bottom of the sleeve 2 through a pipe and is fixedly installed on the column body 1 by a fastener. By designing quartz particles 4 inside the sleeve 2, when wastewater enters the column body 1, it is filtered by the quartz particles 4, and impurities in the wastewater are retained in the gaps between the quartz particles 4, so that the wastewater without impurities is transported into the column body 1, preventing the presence of impurities in the wastewater from affecting the operation of the distillation column during subsequent distillation.

Valves are installed on the surface of both the liquid inlet pipe 11 and the liquid outlet pipe 12. By setting the liquid inlet pipe 11 and the liquid outlet pipe 12, it is convenient to add sewage into the sleeve 2 and allow sewage to enter the interior of the tower body 1.

[0032] refer to Figure 1 The surface of the sleeve 2 is connected to a backwash water pipe 13. There are two backwash water pipes 13, and valves are installed on the surface of the backwash water pipes 13. By setting the backwash water pipes 13, it is convenient to backwash the inside of the sleeve 2 to clean impurities.

[0037] Brief description of the usage process: When external sewage enters the sleeve 2, the quartz particles 4 designed inside the sleeve 2 allow the sewage to enter the tower body 1. The quartz particles 4 filter the sewage and trap impurities in the sewage in the gaps between the quartz particles 4. The sewage without impurities is then pumped into the tower body 1 by the water pump 5, preventing impurities in the sewage from affecting the operation of the distillation tower during subsequent distillation.

An exhaust sleeve 8 is slidably connected inside the sliding sleeve 7. An exhaust groove 9 is formed on the surface of the exhaust sleeve 8. A sealing block 10 is fixedly fitted onto the surface of the exhaust sleeve 8. By installing the shelf 6 inside the column body 1, and installing the sliding sleeve 7 on the shelf 6, with the exhaust sleeve 8 slidably connected inside the sliding sleeve 7, when the gas phase pressure inside the column body 1 is insufficient, the exhaust sleeve 8 retracts into the sliding sleeve 7, sealing the exhaust groove 9. The sealing block 10 contacts the sliding sleeve 7, improving the sealing performance and preventing leakage caused by insufficient gas phase pressure.
