Description
Technical field
The utility model relates to a kind of reactor, specifically, relates in particular to the body of hydrogen cyanide reactor.
Background technology
The hydrogen cyanide reactor is one of core apparatus in the hydrogen cyanide technological process of production, generates the hydrogen cyanide mist by this equipment.Its operation principle is: three kinds of raw materials (ammonia, natural gas, air etc.) that will mix are under computer control, enter the hydrogen cyanide reactor, in equipment, under the catalytic action of catalyst, carry out chemistry (heat release) reaction continuously, produce the hydrogen cyanide mist.The reactor body is the stage casing part of hydrogen cyanide reactor.In the traditional structure, be provided with some heat exchanger tubes in housing, the via hole on the upper perforated plate is passed in the upper end of this heat exchanger tube, and exceeds the end face of fire clay, carries out fillet welding at the place, aperture of via hole between heat exchanger tube and the upper perforated plate and fixes.Because mixed gas burns at upper perforated plate, temperature is up to more than 1000 ℃, and the heat exchanger tube tube head directly contacts high temperature, and scaling loss takes place easily for Yin Gaowen and excessive temperature differentials, thereby influences structural behaviour and service life.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of hydrogen cyanide reactor body that can effectively prevent the heat exchanger tube scaling loss.
The technical solution of the utility model is as follows: a kind of hydrogen cyanide reactor body, in housing, be provided with heat exchanger tube and upper perforated plate, the upper surface of upper perforated plate is provided with fire clay and catalyst, and the position of corresponding heat exchanger tube offers via hole on the upper perforated plate, its key is: the hole wall of described via hole extends downwards, form annular boss, this annular boss is fixed by the top of transit joint and heat exchanger tube, in described via hole, be equipped with and insert pipe, the lower end of this insertion pipe is stretched in the transit joint, and the upper end of inserting pipe exceeds the end face of fire clay and catalyst.
Adopt above technical scheme, adopt transit joint to be connected good manufacturability, dependable performance between heat exchanger tube and the upper perforated plate; Insert pipe and adopt high temperature resistant material to make, make the tube head of heat exchanger tube directly not contact high temperature, effectively alleviated high temperature and excessive temperature differentials and the scaling loss tendency that produces.
For simplified structure, convenient for assembly, the upper end and the annular boss of above-mentioned transit joint connect, and be fixing by welding, and connects with heat exchanger tube after closing up in the lower end of transit joint, also fixing by welding; The step surface that closing in forms in the described transit joint is spacing to the lower end of inserting pipe, and this internal diameter that inserts pipe equates with the internal diameter of heat exchanger tube.
Be provided with cooling tube below above-mentioned upper perforated plate, this cooling tube offers fluid hole near the position of transit joint.The cooling fluid that flows in the cooling tube can further reduce the temperature difference of upper perforated plate wall to transit joint and upper perforated plate spray by fluid hole.
Beneficial effect: the utility model is by changing the connected mode between heat exchanger tube and the upper perforated plate, make the tube head of heat exchanger tube directly not contact high temperature, thereby effectively prevented heat exchanger tube generation scaling loss, ensure the performance and the service life of heat exchanger tube, had reasonable in design, characteristics such as enforcement is easy, dependable performance.
