The gas pipelines are equipped with closed-loop drainage systems to collect the gas. With continuous production, after the coke oven gas is compressed and cooled, a large amount of condensate wastewater is generated. The condensate wastewater contains impurities such as tar, naphthalene, and water. The existing technology usually uses oil separators to collect and treat coking wastewater. However, the oil separators are open structures under normal pressure, which emit a pungent odor, affecting the workshop production environment and urgently need to be improved. Utility Model Content

Detailed Implementation
[0015] like Figure 1 and Figure 2As shown, a coke press wastewater tank includes a tank body 1. A water inlet pipe 2 and a water outlet pipe 3 are connected to the left and right ends of the tank body 1, respectively. An oil drain pipe 4 is connected to the bottom of the tank body 1. A float assembly is installed inside the tank body 1, and a corrugated pipe 7 with vertical extensibility is connected to the bottom of the float assembly. The corrugated pipe 7 is connected to the oil drain pipe 4. Two partitions 15 are vertically arranged inside the tank body 1. The top of the partitions 15 is connected to the tank body 1, and a feed inlet is provided at the bottom of the partitions 15. The float assembly is located between the two partitions 15. Specifically, the float assembly includes a float 5, and a float groove 16 is provided inside the float 5. An overflow hole 6 is opened on the inner wall of the float groove. The corrugated pipe 7 is connected to the float groove 16. To quickly collect the upper layer of oil, the bottom of the float groove 16 is conical. This design aims to reduce contamination. The fluidity of the water allows for more thorough stratification of the wastewater (the upper layer is oily liquid such as tar, the middle layer is condensate, and the lower layer is sludge). Several inclined plates 9 are installed below the floating plate assembly, located between the two partitions 15, and inclined plates 9 are inclined towards the inlet pipe 2. To achieve periodic sludge discharge, several sludge discharge pipes 10 are horizontally connected to the bottom of the tank 1. The sludge discharge pipes 10 are connected to the sludge discharge main pipe 11, and a suction pump is installed on the sludge discharge main pipe 11. A filter plate 8 is connected between the inner wall of the tank 1 and the partitions 15. A waste discharge port 12 is opened on the tank 1, located at the position of the filter plate 8, which can initially filter solid impurities in the wastewater. To facilitate periodic cleaning of the filter plate 8, a cover plate 13 is hinged to the top of the waste discharge port 12, and the bottom end of the cover plate 13 is fixedly connected to the tank 1 by bolts.
[0016] In specific work, such as Figure 1 and Figure 2 As shown, the condensate wastewater enters the tank 1 through the inlet pipe 2. It first passes through the filter plate 8, which initially filters out solid impurities. Then, it passes through the baffle plate 15 and the filter plate 8 for buffering and deceleration, causing the condensate wastewater to separate into layers: the upper layer is oily liquid such as tar, the middle layer is condensate, and the lower layer is sludge. The upper layer of oily liquid is collected in the float tank 16 and the bellows 7 through the overflow hole 6. Due to the buoyancy of the float plate 5, the float plate 5 can rise and fall significantly with the liquid level, making it more adaptable. The suction pump can be turned on periodically to clean the bottom sludge. When the filter plate 8 becomes clogged, the machine can be stopped and the cover plate 13 can be opened to clean the solid impurities on the cover plate 13.
[0017] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
