Description

Technical Field

[0001] The utility model belongs to the technical field of methanol processing, in particular to a methanol tower with a waste heat utilization function. Background Art

[0002] Methanol towers are used in the methanol processing process. Methanol wastewater refers to the distillation residue discharged from the bottom of the distillation tower during the production or use of methanol. Methanol wastewater has a certain amount of heat. If it is discharged directly or directly reacted, it will cause a certain amount of energy waste, so waste heat utilization equipment will be set up in advance. Traditional waste heat utilization devices are mostly one-time utilization, without step-by-step utilization, and cannot effectively increase the temperature of the water liquid.

[0003] After searching, the Chinese patent document (authorization announcement number CN202509069U) discloses a methanol tower waste heat utilization device, which includes a methanol distillation tower, a heating coil, a raw material pool and a pipeline. The heating coil is located in the raw material pool, and the methanol distillation tower is connected to the heating coil in the raw material pool through a pipeline. Due to the above structure, the waste hot water discharged from the methanol distillation tower heats the acidified oil in the raw material pool through the heating coil, making full use of the waste heat discharged from the methanol distillation tower, saving energy and reducing production costs. Most waste heat utilization devices are used once, without step-by-step utilization, and the temperature of the water liquid is not improved. Utility Model Content

[0004] The utility model aims to provide a methanol tower with waste heat utilization function to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a methanol tower with waste heat utilization function, comprising a tower body for processing methanol and a waste water pipe connected to the bottom end of the tower body, a plurality of insulation pipes are sleeved on the outer periphery of the waste water pipe, and the insulation pipes are connected and fixed to the waste water pipe through two connecting ring plates;

[0006] The outer periphery of the wastewater pipe is rotatably connected to a hollow gear through a bearing, the connecting ring plate is connected to a heat-resistant motor through an insulation block, the output shaft of the heat-resistant motor passes through the insulation block and the connecting ring plate and is connected to a driving gear meshing with the hollow gear, the hollow gear is also connected to a connecting rod, the connecting rod is connected to a stirring blade for improving the uniformity of the water liquid, multiple insulation pipes are connected to a water inlet pipe and an auxiliary pipe, some auxiliary pipes are connected to a water outlet pipe and a side branch pipe through a three-way valve, the insulation pipe is connected to a water pump through an insulation frame, the water pump is connected to the side branch pipe, and the water pump is connected to the water inlet pipe of another insulation pipe through a bellows.

[0007] As a preferred embodiment, the insulation pipe and the two connecting ring plates form a waste heat utilization space for storing water, and a perspective window for easy observation is embedded in the side of the insulation pipe.

[0008] As a preferred embodiment, a plurality of thermometers are installed on the side of the insulation pipe.

[0009] As a preferred embodiment, a flange for connecting with a liquid receiving device is connected to the side of the water outlet pipe.

[0010] As a preferred embodiment, a support frame is installed at the bottom end of the tower body, and an inclined plate for connecting with the insulation pipe is provided on one side of the support frame.

[0012] As a preferred embodiment, the connecting rod is equipped with a fan for blowing air to the inclined plate.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The methanol tower with waste heat utilization function has a step-by-step waste heat utilization, and the temperature of the water liquid decreases step-by-step. Therefore, the water liquid at the bottom is pumped to the upper equipment by a water pump to better raise the temperature. In the whole process, the water liquid is in flow, and finally flows out from the top water outlet pipe, and the normal temperature water is in the part far away from the tower body, so as to ensure the effect of waste heat utilization.

[0015] In the methanol tower with waste heat utilization function, during the waste heat utilization process, the heat-resistant motor drives the driving gear to rotate, drives the hollow gear to rotate, and then drives the connecting rod and the stirring blade to rotate, stirs the water liquid, and improves the uniformity of the temperature of the water liquid;

[0016] The methanol tower with waste heat utilization function, with inclined plates, connecting rods and triangular blocks, can improve the stability of the insulation pipe and the waste water pipe. At this time, the fan blows air to reduce the temperature near the waste water pipe.

[0017] The methanol tower with waste heat utilization function can not only effectively increase the temperature of the water liquid, but also better utilize the waste heat. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Multiple insulation pipes 3 are connected to the water inlet pipe 10 and the auxiliary pipe 11, and some auxiliary pipes 11 are connected to the water outlet pipe 13 and the side branch pipe 12 through a three-way valve. The insulation pipe 3 is connected to the water pump 14 through an insulation frame. The water pump 14 is connected to the side branch pipe 12. The water pump 14 is connected to the water inlet pipe 10 of another insulation pipe 3 through a bellows 15. The side of the water outlet pipe 13 is connected to a flange 17 for connecting to a liquid connection device. After a period of time, the water pump 14 draws water from the bellows 15 into another water inlet pipe 10, and finally discharges water from the lowest water outlet pipe 13.
