Abstract
The invention discloses a shell-and-tube heat exchanger with a stock pusher, relates to heat transfer equipment in industrial production, and belongs to the field of gas-liquid heat transfer devices. The shell-and-tube heat exchanger with the stock pusher mainly comprises a rotation mechanism (1), a tube box (5) and a heat exchange tube (9), wherein the rotation mechanism (1) drives the stock pusher (10) in the heat exchange tube (9) to rotate so as to push out liquid and solid, which are condensed on a tube wall, so blocking is avoided. The shell-and-tube heat exchanger with the stock pusher can be applied to heat transfer process in chemical industry, petrochemical industry, light industry, metallurgical industry and the like and has the characteristics of good blocking resistance, remarkable economic benefit and the like.
Description
Technical field
The present invention relates to the heat-transfer equipment of industrial process such as chemical industry, oil, light industry, metallurgy, is a kind of shell-and-tube heat exchanger with pusher concretely, belongs to gas-liquid heat-transfer device field.
Background technology
In industry, wait this type material to adopt common shell-and-tube heat exchanger to lower the temperature usually for the gaseous product behind flue gas, oven gas or some substance reaction (like the product of acetic acid and acetylene); But because the common viscosity of these materials is big and usually contain solid particle; So its flow resistance in heat exchanger tube very greatly and fouling on wall easily, common shell-and-tube heat exchanger is stopped up through regular meeting.Therefore, need frequent heat exchanging device to clean, so increased factory a large amount of maintenance time.
Summary of the invention
The invention provides a kind of shell-and-tube heat exchanger with pusher, viscosity is big and contain the gaseous phase materials cooling of solid particle in can further improve heat transfer efficiency, augmentation of heat transfer effect, the flow regime of improving, effectively solved blockage problem.
In order to achieve the above object; The shell-and-tube heat exchanger of the band pusher that the present invention adopts comprises rotating mechanism 1, bobbin carriage 5 and heat exchanger tube 9; Be provided with spiral (or corrugated in the heat exchanger tube 9; Or other forms) pusher 10; Be provided with water injector 7 above the heat exchanger tube 9; Bobbin carriage 5 is provided with air exhauster 8, and bobbin carriage 5 lower side have the shutter 14 of air inlet.
The present invention compares with known technology and can comment as follows:
Compare with the common tube shell heat exchanger; Though the equipment among the present invention has increased equipment such as rotating mechanism and pusher; And consumes electric power; But the rotation of pusher not only can push out being condensate in liquid on the tube wall, solid etc.; Avoid obstruction, also increased the less turbulence of gas in the heat exchanger tube, improved convective heat-transfer coefficient and the overall heat-transfer coefficient in the pipe; Strengthen heat-transfer effect, thereby can reduce the consumption of cooling medium.
Description of drawings
Specific embodiments of the present invention describes in detail as follows with reference to accompanying drawing:
Fig. 1 is the shell-and-tube heat exchanger sketch map of band pusher.
Fig. 2 is the bobbin carriage sketch map.
Fig. 3 is the heat exchanger tube sketch map of band pusher.
Among the figure: 1, rotating mechanism, 2, main rotary shaft, 3, inferior turning cylinder, 4, the material inlet pipe, 5, bobbin carriage; 6, cooling water inlet pipe, 7, water injector, 8, air exhauster, 9, heat exchanger tube, 10, pusher; 11, material outlet pipe, 12, the waste material mouth, 13, cooling water outlet pipe, 14, shutter.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is explained further details.
Like Fig. 1, Fig. 2, shown in Figure 3, the shell-and-tube heat exchanger of band pusher is made up of rotating mechanism 1, main rotary shaft 2, inferior turning cylinder 3, material inlet pipe 4, bobbin carriage 5, cooling water inlet pipe 6, water injector 7, air exhauster 8, heat exchanger tube 9, pusher 10, material outlet pipe 11, waste material mouth 12, cooling water outlet pipe 13, shutter 14.Rotating mechanism 1 comprises a big main rotary shaft 2 and some little inferior turning cylinders 3.
The operating process of the shell-and-tube heat exchanger of band pusher is following: main rotary shaft 2 drives mechanisms such as sprocket wheel, ratchet, respectively power is sent to each time turning cylinder 3, and inferior turning cylinder 3 drives pusher 10 and rotates.The heat exchanger tube 9 that high-temperature material gets into the band pusher by material inlet pipe 4; Cooling water gets into water injector 7 by cooling water inlet pipe 6; Through the water heat that high-temperature material discharged in the absorption tube on heat exchanger tube 9 that water injector 7 sprays; Part cooling water heat absorption evaporation; The cooling water of vaporization and extracted out by the air exhausters above the bobbin carriage 58 together by the air that shutter 14 gets into; The cooling water outlet pipe 13 of Qi Hua cooling water below bobbin carriage 5 do not discharged; And the motion of spinning that the inner pusher 10 of heat exchanger tube does not stop; So that will be condensate in the liquid on the tube wall; Solids etc. push out; Thereby can avoid the blockage problem of heat exchanger tube 9; Clean; Gas after the cooling is discharged from material outlet pipe 11; By the liquid of pusher 10 releases; Waste materials such as solid drop on waste material mouth 12 places; Waste material mouth 12 seals when flat, opens the waste material mouth after a period of time again and allows liquid; Waste materials such as solid are discharged.
Embodiment: the shell-and-tube heat exchanger with the band pusher among the present invention is lowered the temperature to oven gas.Oven gas also contains mass fraction and is about 10% coke and coal tar except that containing hydrogen and methane.Oven gas is got into the heat exchanger tube of band pusher by the material inlet pipe; Heat discharged the cooling water that gets off to spraying by water injector; On coke in the reduction oven gas of temperature and the continuous inwall attached to heat exchanger tube of coal tar meeting, thereby the pusher that is rotated is released.The mass fraction of coke and coal tar only is 0.1% from the oven gas that the material outlet pipe is discharged, thereby has reached the purpose of removing coke and coal tar in the oven gas.
