Description
One, technical field
The utility model relates to a kind of hydrogen chloride synthetic furnace automatic device of adding acid, is a kind of way of simplifying hydrogen chloride synthetic furnace driving preparation work, and this way has been eliminated the potential safety hazard of manual operation to system's operation simultaneously.
Two, background technology
In producing high-purity hydrogen chloride gas process, need before the start-up system will to add high purity hydrochloric acid in the solidifying acid tube line of hydrogen chloride synthetic furnace first, because stove contains moisture is freezing after the cooling, cause coagulating the danger of acid tube line spalling to prevent in the synthetic furnace startup procedure in solidifying acid tube line; In addition, before driving, increase the high purity hydrochloric acid liquid level, also can make the solidifying acid tube line of synthetic furnace form fluid-tight, make whole building-up process safe and reliable.But mostly the acid adding process is by manual type in the reality, and because this operation frequency of usage is less, often payes attention to seldom for this part, and this has buried many potential safety hazards just for the acid adding process.
Before the operation of tradition synthetic furnace acid adding, do more preparation work, and during the acid adding by the operative employee directly high purity hydrochloric acid is poured into synthetic furnace reserve acid-adding port (＜30mm) in.Reserving acid-adding port only has the blind plate sealing valveless, dismantles blind plate at every turn and will inevitably make emerge corrosion contamination surrounding environment and corrode surrounding devices of acid gas.In the acid adding process, personnel are had relatively high expectations, easily cause the hydrochloric acid outflow, corrosion lower floor's pipeline and equipment.And traditional acid adding process is merely able to carry out when stopping, if synthesis furnace system acid position during driving is not enough, must do then that blowing out is processed and impact is produced.Operate according to traditional way, to airtight qualified, approximately need affected working efficiency more than 2 hours at every turn by Job readiness.
By this patent, easily head it off improves the acid adding process efficiency, and stops the potential safety hazard in the acid adding process.
Three, utility model content
The purpose of this utility model provides the hydrogen chloride synthetic furnace automatic device of adding acid, and it mainly has the following advantages: 1, reduced synthesis furnace system acid adding difficulty, and long-pending by increasing the high purity hydrochloric acid cross section of fluid channel, make the more convenient system that enters of acid solution; 2, add acid system and be arranged at the synthetic furnace top, enter system by gravity, do not need unnecessary power consumption; 3, the high purity hydrochloric acid storage tank is provided with visor, conveniently sees acid position situation in the tank; 4, stopped to cause the excessive situation of high purity hydrochloric acid owing to acid adding operates existing difficulty, reduced the synthetic furnace other parts by the possibility of hcl corrosion.5, reduce the impact of human factor for the acid adding operation, no matter whether synthetic furnace stops, all can carry out this operation.6, device is provided with fluid-tight, prevents back flow of gas.
The purpose of this utility model is achieved like this, and it comprises: high purity hydrochloric acid tank, connection line, the monitoring visor, tensimeter and root valve, high purity hydrochloric acid tank upper end is provided with acid position porthole, observe visor, acid-adding port, acid-adding port blind plate, pressure detection mouth, instrument root valve and on-the-spot tensimeter, high purity hydrochloric acid tank lower end is provided with the acid discharge mouth, the acid adding control valve, and the acid adding control valve is connected with the pipeline of synthetic furnace acid system by anticorrosion material; Described high purity hydrochloric acid tank is lined with the 8mm enamel coating in tank interior.
The utility model hydrogen chloride synthetic furnace acid adding device, it has the following advantages:
One: greatly increased the safety coefficient of synthetic furnace acid adding process, reduced the impact of human factor for the acid adding process safety;
Its two: be arranged on the acid system that adds at synthetic furnace top, make by gravity that hydrochloric acid flows into system smoothly in the tank, do not need the adding of other energy.
Three, by the improvement for acid adding process, greatly increased the efficient of acid adding operation, reduced the operating time.
Its four: whole system is simple in structure, can operate at any time not affected by system's start-stop car, installs easily, has reduced the waste of high purity acid, has reduced production cost and safety cost.
