Description

Stripping tower tail gas furnace-entering condensate water removing device

Technical Field

The utility model belongs to the technical field of the tail gas treatment technique and specifically relates to a strip tower tail gas advances stove and removes comdenstion water device.

Background

The tail gas that the stripper produced is kind harmful gas, can not directly discharge in the atmosphere, it is higher to have the calorific value that some compositions contain in the tail gas, can reduce the use amount of natural gas with its introduction natural gas stove, can burn the tail gas simultaneously, but because tail gas can produce the comdenstion water in its pipeline in transportation process, and the flame that can make the natural gas stove when the comdenstion water gets into the natural gas stove extinguishes, perhaps disturb the fire detection signal that detects flame, thereby all can lead to the production process of natural gas stove shut down stove serious influence polymerization and spinning.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem that the steam stripping tower tail gas enters the furnace and removes the comdenstion water device, which can remove the comdenstion water produced in the tail gas conveying process.

In order to achieve the purpose, the utility model relates to a stripper tail gas enters stove and removes comdenstion water device, including stripper, natural gas stove and the tail gas pipe that is used for carrying tail gas, tail gas pipe carries the tail gas of stripper to the natural gas stove, and the tail gas pipe between natural gas stove and stripper is provided with two low level regions, and one of them low level region is located the intermediate position between stripper and the natural gas stove, and the low level region of another place is located the one end that is close to the natural gas stove; a drain pipe is connected to a tail gas pipe of a low region at the middle position of the stripping tower and the natural gas furnace, the drain pipe is arranged vertically downwards, the connecting position of the drain pipe and the tail gas pipe is positioned on the lower surface of the tail gas pipe, a U-shaped trap is connected to the lower end of the drain pipe, a water outlet of the U-shaped trap is arranged upwards, and a flow limiting valve is arranged at a water outlet of the U-shaped trap; the tail gas pipe of the low-level area close to one end of the natural gas furnace is connected with a liquid storage bag, the lower surface of the tail gas pipe of the low-level area is connected with the liquid storage bag, an emptying pipe is arranged at the bottom of the liquid storage bag, and an emptying valve is arranged on the emptying pipe.

Above-mentioned technical scheme, in the in-service use process, because the stripper tail gas carries to the natural gas stove through the tail gas pipe in, because contain more steam in the tail gas, meet cold formation comdenstion water absorption on the tracheal inner wall of tail gas in the transportation process, finally form the comdenstion water, most comdenstion water can get into the low level district of middle part along the tail gas pipe, drain pipe through this low level district discharges the comdenstion water, and discharge the comdenstion water through U type trap, U type trap can form the water seal in drainage process, avoid the tail gas to discharge, safety and reliability, the discharge velocity of water is adjusted to the accessible current-limiting valve simultaneously, in order to ensure normal drainage speed. In addition, a small amount of condensed water can be deposited in a low-level area at the natural gas furnace and can be accumulated in the liquid storage bag, and the condensed water can be accumulated for a period of time and then be intensively discharged due to the small amount of the condensed water. Above-mentioned scheme can in time discharge the comdenstion water that produces in the tail gas pipe transportation process to avoid it to get into the natural gas stove, safe type is higher.

The flow-limiting valve is connected with a water outlet pipe, and the water outlet pipe extends downwards after being bent.

The utility model provides a strip tower tail gas advances stove and removes comdenstion water device, it is through reasonable structural design, can effectually in time discharge the comdenstion water that produces in the tail gas pipe transportation tail gas in-process, avoids it to get into natural gas stove, safe and reliable.
