Description
The utility model relates to a kind of Φ 1.8m water jacket hydrogen chloride synthetic furnace.
The water jacket hydrogen chloride synthetic furnace is the key equipment that vinylchlorid, hydrochloric acid are produced.The structure of this equipment, life cycle, processing property and safe reliability are very big for the relations of production of subsequent process.The water jacket hydrogen chloride synthetic furnace that present similar manufacturing enterprise uses, the Steel Sheel local corrosion in various degree that exists in service, serious corrosion can penetrate housing and cause water coolant to enter in the synthetic furnace and be forced to stop production.Causing aforementioned corrosive major cause is that synthetic furnace and cooling system structure thereof are unreasonable, make the temperature of cooling water that enters in the chuck low, even the housing outer wall is directly washed away in water inlet, make local housing wall temperature be lower than the dew-point temperature of hydrogenchloride, the water of formation contacts the back and generates hydrochloric acid and just cause and analyse acid corrosion synthetic furnace housing etc. with hydrogen chloride gas.In addition,, cause local temperature to be lower than the hydrogenchloride dew-point temperature, also can produce and analyse acid corrosion, make bottom the water jacket and often occur the housing ring-type near the housing weld seam and corrode because the silt of carrying secretly in the water coolant causes the localized heat transfer poor effect in the water jacket bottom deposit.Therefore, adopt rational water jacket hydrogen chloride synthetic furnace and cooling system structure thereof etc.,, should become the important topic that the planner of hydrogen chloride synthetic furnace extremely pays close attention to solve the etching problem of above-mentioned appearance.
The purpose of the utility model water jacket hydrogen chloride synthetic furnace is to improve water inlet coil pipe outlet temperature of cooling water, make temperature of cooling water even, all be higher than the hydrogenchloride dew-point temperature to reach water jacket hydrogen chloride synthetic furnace housing wall temperature, avoid analysing the local corrosion of the synthetic furnace housing that acid causes, and provide a kind of in water jacket the middle part arrange three layers of hydrogen chloride synthetic furnace that is coiled into furnace shell one week water inlet coil pipe; Also be to reduce in the water silt in the water jacket bottom deposit, and be convenient to clean, improve heat-transfer effect, alleviate and analyse acid corrosion, and hydrogen chloride synthetic furnace that a kind of water jacket bottom is tilted conical etc. is provided.
The technical solution of the utility model can realize like this:
The water jacket hydrogen chloride synthetic furnace mainly comprises water jacket, the visor in housing, its outside, it is characterized in that middle part in the water jacket arranges shellring around the water inlet coil pipe in one week of housing, and respectively it is welded on the water jacket inwall with the U-shaped round steel.
Above-mentioned water jacket hydrogen chloride synthetic furnace, the outlet that it is characterized in that every layer of water inlet coil pipe are tiltedly to be opened towards the water jacket inwall.
Aforesaid water jacket hydrogen chloride synthetic furnace is characterized in that the visor of its underpart, takes over by taper to be welded on the housing.
The above water jacket hydrogen chloride synthetic furnace is characterized in that the water jacket bottom is tilted conical.
The utility model adopts the advantage of above technical scheme to be: because three layers of water inlet coil pipe around one week of housing have been arranged at the middle part in water jacket, can play pre-heat effect to water coolant, make water jacket internal cooling water temp even, and be higher than the hydrogenchloride dew-point temperature, prevent to analyse acid housing is corroded; Water inlet coil pipe outlet prevents that for what tiltedly open towards the water jacket inwall into water directly washes away housing, avoids the local wall temperature of housing to be lower than the dew-point temperature of hydrogenchloride and causes and analyse acid corrosion; The visor of hydrogen chloride synthetic furnace bottom is taken over by taper and is welded on its housing, analyses acid and also can in time flow in the equipment and evaporate even if produce, and alleviates the corrosion of this adapter; With the water jacket bottom design is tilted conical, can alleviate silt deposition herein in the water, also is easy to clean, improving conducts heat improves the housing wall temperature, prevent to analyse acid corrosion, guarantee the operation of water jacket hydrogen chloride synthetic furnace long period safety and steady, to improve output, to reduce production costs etc.
