Technical Field
The utility model relates to the technical field of heptane recovery, and particularly relates to a residual heptane recovery device in a converter.
Background
In the current polyvinyl chloride production process, the normal operation of the converter directly affects the capacity of the system. The heptane required by a single converter is about 8 tons, and the heptane is toxic and extremely flammable, and the explosion limit is 1.1-6.7%. The water content of system water, proportion, natural gas and the like before the conversion process exceeds the standard, and the internal environment of the converter is generally acidic, so that the corrosion of the converter is leaked in the past. In servicing the converter, the heptane on the heptane side of the converter is forced back into the heptane system with nitrogen. Because the heptane side of the lower part of the converter barrel body is at a low point and can not be pressed back to the system, the heptane can flow out when the converter is disassembled for maintenance and the blind plate is added at the heptane side, open fire needs to be started for repair welding of the leakage point of the converter, and the potential safety hazard is great. Thus, heptane recovery at the low point of the converter is a problem that is urgently sought to be solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a device for recovering residual heptane in a converter, which aims to solve the problems in the background technology.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a recovery device for residual heptane in a converter comprises a base and a recovery tank, wherein the recovery tank is of a sandwich structure, a plurality of water inlet branch pipes are uniformly distributed in a sandwich layer, and two ends of each water inlet branch pipe are respectively connected with a water inlet pipe and a water outlet pipe which are arranged on two sides of the recovery tank; a heptane inlet pipe and an exhaust pipe are respectively arranged on two sides of the top of the recovery tank, and a heptane outlet pipe is arranged at the bottom of the recovery tank; a liquid level meter is further fixed on the body of the recovery tank, and a pressure gauge is connected beside the liquid level meter in parallel; the recovery tank is detachably connected with the base.
Further, the height of the water inlet pipe is lower than that of the water outlet pipe; the recovery tank is conveniently cooled, the volatilization of heptane is reduced, and the safety of equipment is improved.
Furthermore, 8-10 water inlet branch pipes are uniformly distributed along the circumferential direction of the recovery tank body.
Further, the upper surface of the base is provided with a radian which is adaptive to the body of the recovery tank; the base is two, places respectively in recovery tank both sides.
Furthermore, a hanging ring is arranged at the top of the recovery tank and used for hanging the recovery tank away from the site.
Compared with the prior art, the utility model has the following beneficial effects:
1. the heptane at the lower point of the converter can be effectively recovered, the technical gap that a heptane recovery system cannot recover completely is filled, the safety of the converter during maintenance is improved, and the personal safety of maintenance personnel is ensured;
2. the whole device has simple and reliable structure, convenient movement and good practicability, avoids environmental pollution caused by heptane leakage and has very high economic benefit.

Detailed Description
The utility model is further described with reference to the following figures and detailed description.
As shown in fig. 1-3, a recovery device for residual heptane in a converter comprises a recovery tank 1 and a base 2, wherein the recovery tank 1 adopts a steel sandwich structure, a plurality of water inlet branch pipes 10 are uniformly distributed in the sandwich structure, two ends of each water inlet branch pipe 10 are respectively connected with a water inlet pipe 5 and a water outlet pipe 6 which are arranged at the left side and the right side of the recovery tank 1, and the height of the water inlet pipe 5 is lower than that of the water outlet pipe 6; a heptane inlet pipe 3 and an exhaust pipe 4 are respectively arranged on two sides of the top of the recovery tank 1, and a heptane outlet pipe 7 is arranged at the bottom of the recovery tank 1; a liquid level meter 9 is also arranged on the body of the recovery tank 1, and a pressure gauge 8 is connected beside the liquid level meter 9; the recovery tank 1 is detachably connected with the base 2.
Specifically, retrieve 1 interbedded edge of jar and evenly be provided with 10 water inlet branch pipes along the hoop for retrieving 1 cooling of jar, prevent that heptane from volatilizing, improve the device security. Base 2 adopts the channel-section steel preparation, controls respectively one, places in retrieving 1 lower parts of jar to the base upper surface has with retrieving 1 jar body assorted radian of jar, so that the more stable jar of retrieving of placing. In addition, rings 11 are welded on two sides of the top of the recovery tank 1 and used for lifting the recovery tank.
When in use, the base 2 is firstly placed at the bottom of the converter, and then the recovery tank 1 is transported to the site by a crane or a forklift and placed above the base 2; after the placement is stable, the water inlet pipe 5 and the water outlet pipe 6 are respectively connected with an external water pipe for water cooling; then, connecting a flange at the end part of a heptane inlet pipe 3 with a heptane outlet at the bottom of the converter, and closing other outlet valves on the recovery tank 1; the heptane at the lower point of the converter was forced into the recovery tank 1 by charging nitrogen gas on the other side of the heptane circulation pipe of the converter, the liquid level gauge 9 was observed, and when the liquid level rose to 60%, the valve of the heptane inlet pipe 3 was closed and the heptane pressurization was stopped. And meanwhile, the pressure gauge 8 is observed to ensure that the pressure in the recovery tank is greater than the pressure in the heptane circulating pipe, so that no leakage is ensured in the filling process, and when the reading of the pressure gauge 8 suddenly rises too fast, the heptane in the converter is emptied. After the filling is finished, a valve on the exhaust pipe 4 is opened for sampling detection, and the oxygen content in the recovery tank is ensured to be lower than a safety value. After sampling and detection are qualified, pressing heptane in the tank into a heptane aftertreatment system through a heptane outlet pipe 7, closing a valve of the heptane outlet pipe 7 after the heptane is pressed, and releasing pressure to micro-positive pressure for later use. When the device is needed to be used at the low points of other heptanes, the device only needs to be moved by a forklift.
