Description

Technical Field

[0001] The invention relates to a condensate collecting device for a coke oven gas primary cooler, in particular to a safe liquid-sealed condensate tank. Background Art

[0002] At present, in the primary cooling unit of the coke oven gas purification device, multiple gas water seal tanks are generally used to collect the coke oven gas condensate of each primary cooler to ensure the continuous and stable transportation of the coke oven gas, and the liquid seal formed inside the gas water seal tank can prevent gas leakage. Due to the formation of a large amount of gas condensate, a condensate tank is also set up to store the gas condensate. The gas condensate flows from the gas water seal tank into the condensate tank and is then sent to the downstream device.

[0003] The entire system has many sets of equipment, occupies a large area, and has many gas leakage points, posing a safety hazard. At the same time, gas entrained in the condensate may enter the downstream equipment, affecting the operating environment and easily causing safety accidents. Summary of the invention

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a safety liquid seal condensate tank, which integrates gas liquid seal and condensate storage in one, solves the environmental pollution problem caused by direct release of vented gas, eliminates the potential safety hazard of a large amount of gas directly entering the pressure balance system, and provides a double safety liquid seal for gas, which is safe and reliable.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A safe liquid-sealed condensate tank, which is a horizontal tank and includes a main body, a condensate liquid-sealing device, a gas phase enclosure, a liquid phase partition and a gas outlet; multiple groups of condensate liquid-sealing devices are provided, the condensate liquid-sealing devices include a condensate inlet pipe and a liquid-sealing pipe, the condensate inlet pipe and the gas outlet are fixedly connected to the top wall of the main body, the condensate inlet pipe extends into the interior of the main body, the liquid-sealing pipe is fixedly connected to the main body and is sleeved on the outside of the condensate inlet pipe; the gas phase enclosure is fixedly connected to the main body, surrounding the multiple groups of condensate liquid-sealing devices and the gas outlet, the multiple groups of condensate liquid-sealing devices and the gas outlet are located in the gas phase enclosure, and the liquid phase partition is fixedly connected to the main body and located outside the gas phase enclosure.

[0007] The number of the multiple groups of condensate liquid sealing devices corresponds to the number of externally connected coal gas primary coolers.

[0008] The main body comprises a sealing head, a circular cylinder and a saddle; the sealing head is fixedly connected to both ends of the circular cylinder, and the saddle is fixedly connected to the bottom of the cylinder.

[0009] The condensate liquid sealing device also includes a vent, which is fixed to the bottom wall of the body; a gap is left between the bottom end of the condensate inlet pipe and the inner wall of the body; and a gap is left between the top end of the liquid sealing pipe and the inner wall of the body.

[0010] The gas phase enclosure plate is cylindrical, with openings at the top and bottom. The top of the gas phase enclosure plate is fixedly connected to the inner wall of the top wall of the main body, the top of the liquid phase partition plate is higher than the bottom of the gas phase enclosure plate, and the bottom of the gas phase enclosure plate is lower than the top of the liquid sealing tube.

[0011] The liquid phase partition is fixedly connected to the inner wall of the bottom wall of the body, dividing the liquid phase space into two parts.

[0012] It also includes a venting pipe and a condensate outlet. The condensate outlet is fixedly connected to the bottom of the head, and the venting pipe is fixedly connected to the top wall of the body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

The gas phase enclosure plates separate the gas phase space and completely isolate the condensate from entrained gas. The liquid phase partition plates separate the liquid phase space and ensure the liquid level height. The present invention integrates gas liquid sealing and condensate storage.

[0015] 2) The present invention is provided with a gas outlet, which is located in the gas phase enclosure. The gas in the gas phase enclosure directly returns to the gas system, eliminating the potential safety hazard of a large amount of gas directly entering the pressure balance system.

[0016] 3) The present invention has a venting pipe at the top, so that the vented gas can be connected to the pressure balance system, avoiding direct venting of the vented gas and solving the environmental pollution problem caused by direct venting of the vented gas.

[0017] 4) The condensate liquid seal device includes a condensate inlet pipe and a liquid seal pipe. The condensate inlet pipe and the gas outlet are fixedly connected to the top wall of the main body. The condensate inlet pipe extends into the interior of the main body.
