Embodiment：

The utility model is described in further detail below in conjunction with the accompanying drawings：

As shown in accompanying drawing 1, Fig. 2, Large Horizontal Container entirety internal combustion heat treatment hot gas flow guide device includes container master Body 4, described one end of container body 4 connect burner, and the top of burner bocca 5 of burner sets fireguard 1, container body 4 middle parts connect some water conservancy diversion temperature-uniforming plates 2, and the other end of container body 4 outlet connection chimney 3, chimney 3 is interior to set chimney butterfly valve apparatus 6；φ 30mm circular hole 7 is uniformly provided with the fireguard 1, the pitch-row of circular hole 7 is 100mm；It is provided with the water conservancy diversion temperature-uniforming plate 2 Reinforcement, improve rigidity；As shown in figure 3, the butterfly valve apparatus 6 includes baffle plate 8, the fixed connection shaft 10 of baffle plate 8, axle 10 penetrates set Axle 9, handle 15 is connected on axle 10, handle 15 is worn by bearing pin 13 connects arc plate 12, and arc plate 12 is provided with hole above, to fixed handle Diverse location；Pass through support bar 11A, support bar B14 connections between arc plate 12 and chimney 3；Handle 15 and arc plate 12 pass through bearing pin 13 connect to wear.The switch of butterfly valve apparatus closes to control fume emission, and then requires control heat according to Technology for Heating Processing It is lost in speed.

The hot gas flow guide device course of work is：Burner combustion diesel oil, produce thermal current and flow from left to right, finally Discharged from chimney.Acted in thermal current flow process by guider, be heated evenly whole turret vessel, temperature difference very little, and then Meet the requirement of heat treatment standard.

Because the kinetic energy of hot gas molecule is more than cold air molecule, the hot-airs of the phase homogenous quantities density compared with cold air is smaller, Form thermal current to float, cold airflow sinks.In heat treatment process, container is added using diesel fuel burner jet flames Heat, substantial amounts of thermal current float, and cause container cavity top and bottom temperature uneven, do not reach Technology for Heating Processing requirement, according to Container diameter size, fireguard is set above burner bocca, hinders moving up for thermal current, avoid upper and lower temperature difference excessive. Fireguard 10mm thickness Q235B carbon steel steel plates, uniformly turn φ 30mm circular hole, pitch-row 100mm on fireguard.

Because the hot spot of horizontal vessel is arranged on one end of container, the temperature and fire end temperature difference of distal end are larger, Technology for Heating Processing requirement can not be met.Therefore the water conservancy diversion temperature-uniforming plate of varying number, water conservancy diversion temperature-uniforming plate are set according to the length of container Is welded because size is bigger than normal by 10mm thickness Q235B carbon steel steel plate and 50 × 50 angle steel, using angle steel as reinforcement, Improve rigidity.The effect of water conservancy diversion temperature-uniforming plate mainly guides the flow direction of thermal current, thermal current is proximally flowed to distal end.

Chimney is used for discharging flue gas, has strict want due to being heat-treated whole heating, constant temperature, the time of cooling and speed Ask, the process of fume emission can take away many heats, it is necessary to have set of system to control the discharge capacity of flue gas.Chimney top is set Umbrella crown, for shading wind and rain, umbrella crown is supported with angle steel；In order to control heat losses speed in real time, butterfly valve apparatus, butterfly are devised The switch of valve gear is closed to control fume emission, and then the loss speed of control heat is required according to Technology for Heating Processing.

The baffle plate of chimney welds together with axle, and fume emission and heat losses speed are controlled by adjustment position.Branch Strut 11A, support bar B14 are support angle steel, to supporting arc plate, are drilled above arc plate, to the different positions of fixture handle Put, connect with bearing pin to wear.

Large Horizontal Container entirety internal combustion heat treatment hot gas flow guide device is applied to 1,200,000 tons/year of second of Daqing petrochemical The bulk heat treatmet of the prefabricated mm ethene liquid separation tanks of 1 specification φ 5200 × 16 of alkene reconstruction and extension project and Daqing Refinery high-pressure fire Torch Control of Hidden engineering 1 prefabricated high pressure flare water sealed tank φ 5800 × 32 × 19964 and 1 high pressure flare liquid separation tank φ In 5800 × 36 × 19964 bulk heat treatmet, the flow direction of thermal current, heating, constant temperature, drop can be guided in application process automatically Whole turret vessel heating-up temperature is uniform in warm whole heat treatment process, and heat treatment cycle curve meets standard requirement, achieves good effect Fruit.
