Abstract
The utility model discloses a plate air preheater with a water cooled pipe which is an important energy-saving apparatus in black carbon production industry, mainly comprising a casing body, a tube array which is arranged in the casing body, pipe plates, and waste heat flue gas inlet and outlet pipes. The pipe plates and the waste heat flue gas inlet and outlet pipes are welded on the upper and lower ends of the casing body. The utility model is characterized in that the pipe plates are arranged additionally in the casing body of the preheater. A pipe plate cooler is formed by the pipe plates which is arranged additionally, and the original pipe plate. Water inlet pipe and water outlet pipe are arranged on the pipe plate cooler. The utility model has the advantage of long service life, and has the advantages that the temperature of the waste heat flue gas inlet can be increased, and thereby, the preheating temperature of the air can be increased.
Description
The utility model is a kind of water cooling tube plate air preheater, it is the important energy-efficient equipment that uses in the production of carbon black industry, it mainly by housing, be installed in the intravital tubulation of shell and be welded on housing that up and down the tube sheet at two ends and the parts such as waste heat flue gas import and export pipe that are located on the housing are formed.
At present, the air preheater major part of using in the carbon black industry is the shell-and-tube preheater, mainly is made up of parts such as waste heat flue gas inlet tube, outlet pipe, last lower tubesheet, housing, tubulations.Last lower tubesheet and tubulation, housing all connect together by welding, have traverse baffle to change the flow state of air in the housing, strengthen heat-transfer effect.Its working process is that high temperature carbon black smoke (waste heat flue gas) is walked in the pipe (being tube side), and Cryogenic air is walked in the housing (being shell side), reaches cooling carbon black gas, utilizes waste heat to add the purpose of warm air.The preheater of this structure, make with plain carbon stool or with stainless steel no matter be, in general, one or two months at least, half a year damage in various degree will take place at most, prove that after deliberation the reason of its damage is the axial saddle type temperature distribution that the hoop position of the tubulation mouth of pipe and panel weld heat affected zone exists, the yield strength that the thermal stresses that this thermograde produced surpasses material causes it to be damaged.
The purpose of this utility model provides with regard to being to overcome above-mentioned weak point of the prior art that a kind of structure is more reasonable, the water cooling tube plate air preheater of long service life.
The purpose of this utility model can realize by following measure: set up tube sheet in the housing of preheater, the tube sheet of newly establishing and original tube sheet and tubulation are formed the tube sheet water cooler jointly, on the cooler casing water-in and water-out water pipe are housed.
Water cooling tube plate air preheater of the present utility model respectively has additional a tube sheet at waste heat flue gas inlet end and outlet side, also can only set up a tube sheet at inlet end.
The drawing of accompanying drawing is described as follows:
Accompanying drawing is a structure iron of the present utility model.
Do with detailed description below with reference to embodiment (accompanying drawing): the utility model mainly is made up of housing and tubulation, tubulation (8) is distributed in the housing (7), the two ends up and down of housing are tube sheet (3), also be provided with two tube sheets (5) in the housing, tube sheet (3), (5) fuse with the method for welding and housing (7) and tubulation (8); Tube sheet (3) and tube sheet (5) and tubulation (8) are formed the tube sheet water cooler jointly, and water cooler is provided with water-in and water-out water pipe (4).Traverse baffle (9) is housed in the housing, is used for changing the mobile dress attitude of air.Housing is provided with air intlet pipe and outlet pipe (6), and the two ends up and down of housing are connected with waste heat flue gas inlet tube and outlet pipe (1) by bolt.(10) are expansion joint among the figure, and (2) are ring flange.
Working process of the present utility model is as follows: the high temperature carbon black smoke enters tubulation through flue gas inlet tube and is discharged by smoke outlet tube, air enters housing by the air intlet pipe, changing the dress attitude that flows through traverse baffle strengthens conducting heat, the heating back is discharged by the air pipe, and the heated process of air is pyrocarbon black smoke gas refrigerative process just.Owing to two ends about the utility model is in housing have respectively increased a tube sheet, thereby make the two ends up and down of preheater respectively increase a tube sheet water cooler, water coolant enters water cooler by water inlet pipe, heated water is discharged via the water outlet water pipe, thereby reach the purpose that reduces the tube sheet temperature, the life-span of tube sheet is prolonged greatly, also just make increase the working life of preheater.
The utility model has the following advantages:
Long service life has reduced the turnover rate of equipment, thereby has improved economic benefit. Owing to increased the tube sheet cooler at preheater, can improve the temperature of import carbon black smoke, thereby also just can improve the preheating of air temperature.
Claims (3)
1, a kind of water cooling tube plate air preheater, it is the important energy-efficient equipment in the production of carbon black industry, it mainly by housing (7), be contained in the intravital tubulation of shell (8) and be welded on housing that up and down the tube sheet (3) at two ends and waste heat flue gas import and export pipe (1) etc. are formed, of the present utility model being characterised in that: have additional tube sheet (5) in the housing of preheater, tube sheet (3) is formed the tube sheet water cooler jointly with tube sheet (5) and tubulation (8), is located at water-in and water-out water pipe (4) on the cold moving device.
2, water cooling tube plate air preheater according to claim 1 is characterized in that: waste heat flue gas inlet end has additional tube sheet (5).
3, water cooling tube plate air preheater according to claim 1 is characterized in that: waste heat flue gas inlet end and outlet side respectively have additional a tube sheet (5).
