DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1As shown, the closed collection device for hydrolyzate of the present invention comprises a discharge tank 1 for storing discharged hydrolyzate, a feed pipe being provided on the discharge tank, and the feed pipe being used to transport the discharged hydrolyzate to the discharge tank; a nitrogen inlet pipe 10 being provided on the discharge tank 1, and a nitrogen discharge pipe 11 being provided on the top of the discharge tank 1, the nitrogen inlet pipe 10 and the nitrogen discharge pipe 11 being provided with a first valve 12 and a second valve 13 respectively for controlling the introduction and discharge of nitrogen in the discharge tank; a safety valve 5 being installed on the top of the discharge tank 1 for ensuring the safety of the discharge tank in a sealed state; a pressure gauge 7 being provided on the top of the discharge tank 1 for monitoring the pressure change in the discharge tank; a submersible pump 9 being provided in the inner center of the discharge tank 1 for transporting the hydrolyzate in the discharge tank to a predetermined position.

[0021] As a preferred embodiment, the discharge tank 1 is a horizontal cylindrical tank placed in a pit outside the tank firebreak. Its bottom surface is connected to a support. The pit is recessed in the ground 15 and equipped with a canopy and a water pump to prevent rainwater accumulation. The capacity of the discharge trough can be adjusted to 30 cubic meters or larger or smaller depending on actual needs, making it suitable for tank farms of varying sizes.

[0022] As a preferred solution, the feed pipeline includes a feed pipeline 2 and a feed pipeline 3, which are respectively used to transport hydrolyzates with different flow rates.

[0023] As a preferred solution, the feed pipe is the feed pipe 2 , and the feed pipe 2 is provided with a first control valve 2 ′ for controlling the delivery of the discharged hydrolysate in the storage tank to the discharge tank 1 .

[0024] As a preferred solution, the feed pipe is the feed pipe 3 , and the feed pipe 3 is provided with a second control valve 3 ′ for controlling the delivery of the hydrolyzate discharged from the pre-pump filter to the discharge tank 1 .

[0025] As a preferred solution, the feed pipe 10 extends into the interior of the discharge tank 1, ensuring uniform distribution of the material upon entry, minimizing bubble formation and stratification. A regulating valve 14 is installed on the feed pipe to adjust the feed rate as needed. The feed pipe can also be connected to other discharge points besides the storage tank and pre-pump filter to meet various discharge requirements.

[0026] As a preferred embodiment, the nitrogen inlet pipe 10 and the nitrogen outlet pipe 11 control the introduction and discharge of nitrogen in the discharge tank through the first valve 12 and the second valve 13, thereby regulating the pressure within the discharge tank. Nitrogen is introduced into the discharge tank 1 through the nitrogen inlet pipe 10, creating an inert gas environment within the discharge tank to prevent the accumulation of combustible gases. When the pressure within the discharge tank exceeds a preset safety threshold, the second valve 13 automatically activates and discharges the nitrogen to the atmosphere, thereby reducing the pressure within the discharge tank.

[0027] As a preferred solution, the pressure gauge 7 is connected to the remote controller, the nitrogen inlet pipe, and the nitrogen outlet pipe, respectively, to monitor pressure changes in real time via remote monitoring equipment. When the pressure gauge detects that the pressure exceeds the set value, the second valve 13 is automatically activated to release excess pressure. When the pressure exceeds the set value of the safety valve, the safety valve 5 automatically opens to further release pressure.

[0028] As a preferred solution, a liquid level gauge 8 is installed inside the discharge tank, connected to a remote controller and pressure gauge, allowing real-time monitoring of liquid level changes via remote monitoring equipment. When the liquid level gauge detects an excessively high liquid level, the remote controller closes the feed pipe regulating valve 14. High liquid levels can lead to increased pressure, and the level gauge's alarm signal provides an early warning, closing the discharge tank feed pipe regulating valve 14 to prevent the safety valve from frequently actuating due to excessive pressure.

[0029] As a preferred embodiment, a thermometer 6 is installed on the top of the discharge tank, connected to a remote controller and a pressure gauge, to monitor temperature changes in real time via remote monitoring equipment. When the thermometer detects that the temperature in the discharge tank is too high, the nitrogen-venting interlocking system is activated to reduce the temperature by introducing nitrogen. High temperature may cause pressure to rise, and the alarm signal from the thermometer provides an early warning. At this time, the second valve 13 is automatically activated to release excess pressure, preventing the safety valve from frequently actuating due to excessive pressure.

[0030] As a preferred solution, a thermometer, a pressure gauge and a liquid level gauge are provided according to the needs of the discharge tank. The utility model provides a thermometer, a pressure gauge and a liquid level gauge on the discharge tank to ensure the stability of the internal pressure of the discharge tank.

[0031] The working principle of the utility model is as follows: when in use, the first valve 12 and the second valve 13 of the nitrogen ventilation pipe 10 are opened to introduce nitrogen into the discharge tank. When the discharge tank 1 is filled with nitrogen, the second valve 13 is closed; the regulating valve 14 on the feed pipe is opened, and the hydrolyzate enters the discharge tank 1 through the feed pipe 2 or 3. When the pressure in the discharge tank exceeds the set value of the pressure gauge, the nitrogen-venting chain 4 is automatically started, the first valve 12 is closed, and the second valve 13 is opened, and the excess pressure is released through the second valve 13 to prevent overpressure; if the second valve 13 fails, resulting in an abnormal increase in the pressure in the discharge tank, the safety valve 5 is automatically opened to release the excess pressure to ensure the safety of the discharge tank and personnel; after the storage tank is inspected and maintained or the filter is unblocked, the submersible pump 9 is turned on to transport the hydrolyzed material to the storage tank.

[0032] The hydrolyzate closed collection device of the utility model can effectively prevent material leakage and improve the safety and convenience of operation; the multiple protection mechanisms of the nitrogen-venting interlocking system and the safety valve ensure rapid response in emergency situations and prevent accidents.

[0033] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
