Description

Technical Field

[0001] This invention belongs to the field of condensate recovery technology, and particularly relates to a solvent device for condensate recovery and reuse. Background Technology

[0002] The existing process cannot recycle the condensate generated by the solvent reboiler in the solvent unit of the needle coke plant. The generated condensate cannot be directly fed into the condensate network due to high pipeline pressure. Even if it were incorporated into the condensate network, the heat source would be insufficient for the solvent unit reboiler, failing to meet process requirements. Currently, it can only be discharged separately to the coke pool to replace fresh water, increasing production costs. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a solvent recovery and condensate reuse machine, which has a simple structure, can greatly reduce operating costs, and can also reduce water waste.

[0004] The technical solution is as follows: a solvent device for recovering and reusing condensate includes a reboiler, wherein an inlet pipe is installed on the left side of the reboiler; a one-way valve is installed on the left side of the inlet pipe, characterized in that an outlet pipe rack structure is provided on the right side of the reboiler; a cooling maintenance rack structure is installed on the right side of the outlet pipe rack structure; and a recycling device is provided at the lower part of the cooling maintenance rack structure.

[0005] Preferably, the recycling device includes a circulation pump, a circulation pipe is installed at the front inlet of the circulation pump; a return pipe is installed on the left side of the circulation pump; and a solenoid valve is installed on the upper side of the return pipe.

[0006] Preferably, the outlet tube frame structure includes a conveying tube, and an inclined filter screen is provided in the middle of the conveying tube; a transparent outlet tube is provided below the inclined filter screen and is installed in the lower part of the conveying tube; control valves are respectively provided on the upper and lower sides of the transparent outlet tube.

[0007] Preferably, the cooling maintenance rack structure includes a cooling tower, which is connected to the right side of the delivery pipe and the upper side of the circulation pipe respectively; a maintenance cover is provided on the lower front side of the cooling tower; a protective filter screen is provided on the bottom inner side of the cooling tower; and an outlet valve is provided on the lower right side of the cooling tower.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] In this invention, a circulating pump is used to conveniently recycle and reuse the condensate from cooling through a circulating pipe, thereby greatly reducing water waste and lowering operating costs.

[0010] When using this invention, the upper control valve is opened, and then the soda can be filtered using an inclined filter screen to prevent impurities from entering to the right. The impurities are stored using a transparent outlet pipe. After filtering for a period of time, the upper control valve is closed, and then the lower control valve is opened to allow the filtered residue to be discharged downwards.

[0011] In this invention, a protective filter screen is used to facilitate the filtration of slag and residue. At the same time, the outlet valve is opened to facilitate the discharge of condensate from inside the cooling tower. The maintenance cover can also be opened to maintain and clean the protective filter screen. Attached Figure Description

[0019] Example:

[0020] As attached Figure 1 and attached Figure 4As shown, this invention provides a solvent recovery and condensate recycling machine, including a reboiler 1. An inlet pipe 2 is installed on the left side of the reboiler 1; a one-way valve 3 is installed on the left side of the inlet pipe 2. The reboiler 1 is characterized by having an outlet pipe support structure 4 on the right side; a cooling maintenance rack structure 5 is installed on the right side of the outlet pipe support structure 4; a recycling device 6 is installed at the lower part of the cooling maintenance rack structure 5; the recycling device 6 includes a circulation pump 61, a circulation pipe 62 is installed at the front inlet of the circulation pump 61; a return pipe 63 is installed on the left side of the circulation pump 61; and a solenoid valve 64 is installed on the upper side of the return pipe 63. The circulation pump 61, through the circulation pipe 62, facilitates the recycling of cooled condensate, thereby significantly reducing water waste and lowering operating costs.

[0021] As attached Figure 2 As shown in the above embodiment, specifically, the outlet pipe rack structure 4 includes a conveying pipe 41, and an inclined filter screen 42 is provided in the middle of the inside of the conveying pipe 41; a transparent outlet pipe 43 is provided at the lower part of the inclined filter screen 42, and the transparent outlet pipe 43 is installed at the lower part of the conveying pipe 41; control valves 44 are respectively provided on the upper and lower sides of the transparent outlet pipe 43. When in use, the upper control valve 44 is opened, and then the inclined filter screen 42 can be used to filter the soda water, thereby preventing impurities from entering to the right and storing them in the transparent outlet pipe 43. After filtering for a period of time, the upper control valve 44 can be closed, and then the lower control valve 44 can be opened to discharge the filtered residue downwards.

[0025] Working principle

[0026] In operation, deoxygenated water is added to the reboiler 1 through the inlet pipe 2. After being processed by the reboiler 1, the water is conveyed to the right through the conveying pipe 41, with the upper control valve 44 normally open. The water is filtered by the inclined filter screen 42 to prevent impurities from entering to the right. The water is stored through the transparent outlet pipe 43. After filtration for a period of time, the upper control valve 44 can be closed, and then the lower control valve 44 can be opened to discharge the filtered residue downwards. The cooling tower 51 is used to cool the residue and obtain condensate. The protective filter screen 53 facilitates the filtration of the residue. The outlet valve 54 is opened to facilitate the discharge of condensate from the cooling tower 51. The maintenance cover 52 can be opened to maintain and clean the protective filter screen 53. Finally, the circulating pump 61 and the circulating pipe 62 facilitate the recycling of the cooled condensate, thereby greatly reducing water waste and lowering operating costs.
