Background

In the domestic chlor-alkali industry, the process of generating hydrogen chloride gas by burning hydrogen and chlorine in a two-in-one graphite synthesis furnace is widely used, and with the use of a hydrochloric acid synthesis furnace production device, an old-fashioned acid condensation discharging method is controlled by a valve and a test mirror, and when the liquid level of the acid condensation in the test mirror exceeds half, the valve is opened to discharge the acid condensation through a pipeline. However, if the valve is not tight and/or the flange port leaks, the gas in the furnace can leak, and if the gas is serious, the flame in the furnace can be sprayed outwards, which is mainly caused by the aging, corrosion and deformation of gaskets of the furnace end of the synthesis furnace and the acid discharge pipeline of the furnace end. Although personnel inspection is available, the time from gas leakage to flame outward spraying is very short due to the fact that the pressure inside the furnace is greatly different from the pressure outside the furnace, and therefore once leakage occurs, the method is a huge hidden danger for workers and a synthesis furnace.

Detailed Description

Referring to fig. 1, the embodiment of the utility model provides a pair of two unification graphite synthetic furnace congeal sour discharging equipment, congeal sour canister 10 including the synthetic furnace, the synthetic furnace congeals the top of sour canister 10 and communicates through the furnace top of first pipeline 30 and two unification graphite synthetic furnaces 20, and the synthetic furnace congeals the stove bottom intercommunication of sour canister 10 through second pipeline 40 and two unification graphite synthetic furnaces 20, and the middle part of synthetic furnace congeals sour canister 10 sets up third pipeline 50 and is used for congealing the sour discharge of congealing in the sour canister 10 with the synthetic furnace. An automatic valve 60 is provided in the third line 50, and a liquid level meter 70 is provided on the side wall of the small acid condensation tank 10 of the synthesis furnace. When the liquid level of the liquid level meter 70 is high, the automatic valve 60 automatically opens, the condensed acid in the small condensed acid tank 10 of the synthesis furnace is discharged along the third pipeline 50 due to the furnace pressure, and when the liquid level of the liquid level meter 70 reaches a low level, the automatic valve 60 automatically closes. Wherein, the export of being connected of third pipeline 50 and synthesizer acid condensing tank 10 is higher than the import of being connected of second pipeline 40 and synthesizer acid condensing tank 10, as the utility model discloses a concrete embodiment, the export of being connected of third pipeline 50 and synthesizer acid condensing tank 10 exceeds the import of being connected of second pipeline 40 and synthesizer acid condensing tank 10 and is about 200mm, forms the liquid seal of the import of being connected of high second pipeline 40 and synthesizer acid condensing tank 10 in synthesizer acid condensing tank 10 like this, under the hydraulic action of liquid seal, can avoid the valve that old-fashioned discharge system takes place not tight, the flange mouth reveals and causes events such as stove flame outer blowout, has avoided the serious influence that causes equipment instruments such as personnel's safety and synthesizer and pipeline.

In addition, a manual valve 80 is provided on the first line 30. The sight glass 90 is arranged at the connecting outlet of the third pipeline 50 and the small acid condensing tank 10 of the synthesis furnace, the acid condensing phenomenon can be observed from the site through the sight glass 90, and whether acid condensing bubbles exist in the condensed acid can also be observed, so that the safety of the automatic valve 60 can be ensured.

In order to ensure that the small acid condensation tank 10 of the synthesis furnace and the two-in-one graphite synthesis furnace 20 are connected more firmly and durably and prevent pipelines in the device from being corroded by the condensed acid, the first pipeline 30 adopts DN50 steel lined PTFE pipeline, the second pipeline 40 adopts DN80 steel lined PTFE pipeline, and the third pipeline 50 adopts DN50 steel lined PTFE pipeline.

The utility model provides a pair of two unification graphite synthetic furnace congeal sour discharging equipment, its theory of operation as follows: the manual valve 80 on the first pipeline 30 is opened, and the condensed acid in the two-in-one graphite synthesis furnace 20 respectively enters the small condensed acid tank 10 of the synthesis furnace from the first pipeline 30 at the top of the furnace and the second pipeline 40 at the bottom of the furnace. Since the automatic valve 60 disposed on the third pipeline 50 and the liquid level meter 70 disposed on the side wall of the small acid condensing tank 10 of the synthesis furnace belong to the instrument control module, the liquid level of the liquid level meter 70 is converted into an electric signal through the transmission and transmitted to the automatic valve 60, and then the automatic valve 60 adjusts the valve switch thereof according to the signal. When the liquid level of the liquid level meter 70 is high, the automatic valve 60 is automatically opened, because the top and the bottom of the two-in-one graphite synthesis furnace 20 are both communicated with the synthesis furnace small acid condensation tank 10, the pressure in the synthesis furnace small acid condensation tank 10 is approximately equal to the furnace pressure in the two-in-one graphite synthesis furnace 20, and the condensed acid in the synthesis furnace small acid condensation tank 10 is pressed out from the third pipeline 50 under the furnace pressure in the two-in-one graphite synthesis furnace 20. When the liquid level of the liquid level gauge 70 is low, the automatic valve 60 is automatically closed, and the discharge of the condensed acid is temporarily stopped. At this time, although the level of the condensed acid in the small synthesis furnace condensed acid tank 10 is lowered, the connection outlet of the third pipeline 50 and the small synthesis furnace condensed acid tank 10 is higher than the connection inlet of the second pipeline 40 and the small synthesis furnace condensed acid tank 10 by about 200mm, so that a liquid seal higher than the connection inlet of the second pipeline 40 and the small synthesis furnace condensed acid tank 10 by 150-250mm is always formed in the small synthesis furnace condensed acid tank 10, and the liquid seal function is always performed on the connection inlet of the second pipeline 40 and the small synthesis furnace condensed acid tank 10, thereby ensuring that no flame outward spraying event occurs at the bottom of the two-in-one graphite synthesis furnace 20.
