Description

Technical Field

[0001] This utility model relates to the field of gas circulation treatment, and in particular to an evaporation water vapor recovery and utilization system for a carbonization furnace. Background Technology

[0002] The burning of charcoal produces water vapor, which is released along with organic compounds such as tar, acids, alcohols, and aldehydes, forming high-temperature, high-humidity, and highly polluting flue gas. The main method for treating this water vapor is to lead it through sealed pipes to condensation equipment for gas-liquid separation. However, as the water vapor passes through the sealed pipes, droplets easily condense on the pipe walls. If these droplets are not treated in time, they can accumulate inside the pipes, affecting the subsequent passage of water vapor, thus requiring more frequent cleaning and increasing labor costs. Utility Model Content

[0003] To address the aforementioned problems, this invention provides an evaporation water vapor recovery and utilization system for a carbonization furnace, which enables timely return of condensed droplets for processing, reducing accumulation and lowering the frequency of cleaning.

[0004] The technical solution of this utility model is as follows:

[0005] A system for recovering and utilizing evaporative water vapor in a carbonization furnace includes an inlet pipe, a conveying pipe, a quench tower, a collection tank, and a separation device. The inlet pipe is connected to the middle of the conveying pipe, and the two ends of the conveying pipe are a gas outlet and a liquid outlet, respectively. The gas outlet of the conveying pipe is connected to the gas input end of the quench tower, and the liquid outlet of the conveying pipe is connected to the input end of the collection tank. The output end of the collection tank is provided with a first recovery pipe, and the gas output end of the quench tower is provided with a second recovery pipe. The separation device is provided with a liquid inlet, a water outlet, and an oil outlet. The first and second recovery pipes are both connected to the liquid inlet of the separation device. A circulation pipe is provided at the water outlet, and the end of the circulation pipe is connected to the water tank of the quench tower. A circulating water pump is provided on the circulation pipe.

[0006] In a further technical solution, a condenser is also provided in the middle of the second recovery pipe.

[0007] In a further technical solution, the separation device is a liquid storage tank.

[0008] In a further technical solution, the separation device is an oil-water separator.

[0009] In a further technical solution, an oil drain pipe is provided at the oil drain port, the oil drain pipe is an L-shaped pipe that bends downwards, and a cleaning port is provided at the bend of the oil drain pipe.

[0010] In a further technical solution, a heating plate is provided on the outer side of the end of the oil drain pipe.

[0011] In a further technical solution, a heat insulation sleeve is provided on the outer side of the heating plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. The flue gas discharged from the carbonization furnace can enter the conveying pipe. The first condensed droplets can flow back to the collection tank through the liquid outlet, reducing the accumulation in the conveying pipe and reducing the cleaning frequency. The flue gas enters the quench tower through the gas outlet for cooling, which can separate non-condensable gases for separate treatment. The remaining tar and water mixture is transported to the separation device for treatment through the second recovery pipe. The mixture in the collection tank before treatment and the mixture treated in the quench tower are combined and fed into the separation device. The separation device performs oil-water separation treatment. The separated tar is discharged from the oil outlet, and the separated wastewater can be discharged through the water outlet and transported to the quench tower for spraying.

[0014] 2. The condenser can further cool the gas entering the second recovery pipe through the quench tower to room temperature, so that most of the water vapor and tar are condensed into condensate, which is beneficial for recovery;

[0015] 3. A cleaning port is provided to facilitate the removal of tar from the oil drain pipe;

[0016] 4. The heating plate can raise the temperature at the low-temperature position of the oil drain pipe, which makes it easier to improve the fluidity of the tar and further facilitates cleaning. Attached Figure Description

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figure 1As shown, an evaporation water vapor recovery and utilization system for a carbonization furnace includes an inlet pipe 10, a conveying pipe 20, a quench tower 30, a collection tank 40, and a separation device 50. The inlet pipe 10 connects to the middle of the conveying pipe 20, with the two ends of the conveying pipe 20 being an outlet for gas and an outlet for liquid, respectively. The outlet of the conveying pipe 20 is connected to the gas input end of the quench tower 30, and the outlet of the conveying pipe 20 is connected to the input end of the collection tank 40. The outlet is vertically downward to facilitate the reflux of condensed liquid under gravity. The output end of the collection tank 40 is equipped with a first recovery pipe 41, which is connected to the first... A valve 42 is provided between the first recovery pipe 41, which is normally closed and is opened when oil and water are separated. A second recovery pipe 31 is provided at the gas output end of the quench tower 30, and a condenser 32 is also provided in the middle of the second recovery pipe 31. The separation device 50 can be a liquid storage tank, which is provided with an inlet, a water outlet and an oil outlet. The first recovery pipe 41 and the second recovery pipe 31 are both connected to the inlet of the separation device 50. A circulation pipe 52 is provided at the water outlet. The end of the circulation pipe 52 is connected to the water tank of the quench tower 30. A circulation water pump 53 is provided on the circulation pipe 52.

[0024] The working principle of the above technical solution is as follows:

[0025] The flue gas discharged from the carbonization furnace can enter the conveying pipe 20. The condensed droplets can be returned to the collection tank 40 through the liquid outlet, reducing the accumulation in the conveying pipe 20 and reducing the cleaning frequency. The flue gas enters the quench tower 30 through the gas outlet for cooling, which can separate non-condensable gases for separate treatment. The remaining tar and water mixture is transported to the separation device 50 for treatment through the second recovery pipe 31. The condenser 32 can further cool the gas entering the second recovery pipe 31 through the quench tower 30 to room temperature, so that most of the water vapor and tar are condensed into condensate, which is beneficial for recovery. The mixture in the collection tank 40 before treatment and the mixture treated by the quench tower 30 are combined and fed into the separation device 50. The separation device 50 can perform oil-water separation treatment by static stratification. The separated tar is discharged from the oil outlet, and the separated wastewater can be discharged through the water outlet and pumped to the quench tower 30 for spraying by the circulating water pump 53.

[0026] In another embodiment, the difference from the above embodiment is that the separation device 50 is an oil-water separator.

[0027] It can accelerate the oil-water separation process and improve efficiency.

[0028] In another embodiment, such as Figure 1-2 As shown, an oil drain pipe 51 is provided at the oil drain port. The oil drain pipe 51 is an L-shaped pipe that bends downwards. A cleaning port 54 is provided at the bend of the oil drain pipe 51. The cleaning port 54 can be closed with a flange cover before and after cleaning.

[0029] The cleaning port 54 is provided to facilitate the cleaning of tar in the oil drain pipe 51.

[0030] In another embodiment, such as Figure 1-2 As shown, a heating plate 55 is provided on the outer side of the end of the oil drain pipe 51; a heat insulation sleeve 56 is provided on the outer side of the heating plate 55, and the heat insulation sleeve 56 can be made of rock wool.

[0031] The heating plate 55 can raise the temperature of the low-temperature position of the oil drain pipe 51, which can easily improve the fluidity of the tar and further facilitate the cleaning of the tar in the oil drain pipe 51. The heat insulation sleeve 56 prevents the operator from accidentally touching it.

[0032] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
