Description
Technical field
The utility model belongs to radiant tube field, is specifically related to a kind of use Steam Heating radiant tube, then carries out thermal-radiating steam radiant tube.
Background technology
Radiant tube is a kind of heat that utilizes combustion inner pipe gas combustion to produce, and taking heat radiation as principal mode, heat is delivered to the heater of heating object by the tube-surface being heated.Its combustion atmosphere does not contact with heating object with product, and heat treatment is to carry out under protective atmosphere completely, in the production process that therefore radiant tube is applicable to product quality to have relatively high expectations.
Existing radiant tube is all to adopt burning gases burning to produce heat, not only larger to the demand of burning gases, and burning gases meeting generation waste gas after burning, and waste gas must just can reach discharge standard after effective processing.Therefore use existing radiant tube in the time heating, not only heating cost is higher, and follow-up processing cost is higher equally.
Therefore, developing a kind of radiant tube that heats that required cost is low and subsequent treatment cost is low or do not need to carry out subsequent treatment is those skilled in the art institute urgent need to solve the problem.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of use Steam Heating radiant tube, then carry out thermal-radiating steam radiant tube.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of steam radiant tube, comprises radiant tube body, heating furnace, steam-water separator and steam superheater; Heating furnace is connected with steam-water separator; Steam-water separator is connected with steam superheater; Radiant tube body comprises bend pipe, upper straight tube and lower straighttube; The two ends of bend pipe are connected with upper straight tube and lower straighttube respectively; Upper straight tube is connected with steam superheater; Lower straighttube is connected with the top of heating furnace by condenser pipe; The junction of condenser pipe and lower straighttube is also provided with temperature control valve (TCV).
The utility model provides a kind of steam radiant tube, is made up of radiant tube body, heating furnace, steam-water separator and steam superheater.
First cold water or pure water heat in heating furnace, and the temperature in heating furnace rises gradually, and moisture evaporates gradually; Moisture and steam arrive steam-water separator subsequently, moisture separates in steam-water separator with steam, moisture is come back in heating furnace, and steam upwards arrives in steam superheater, further be heated to after overtemperature, enter in radiant tube body, the heated material of radiant tube body outside is carried out to heat radiation.
Steam in radiant tube body according on the sequential flowing of straight tube, bend pipe, lower straighttube, arrive after lower straighttube, form aqueous water by condenser pipe, flow back in heating furnace.
As preferably, the outer surface of lower straighttube is provided with temperature inductor; Temperature inductor is connected with temperature control valve (TCV) and heating furnace respectively.
The utility model is provided with temperature inductor at the outer surface of lower straighttube, can set a predetermined temperature value for the different object of heating, in the time that the temperature of the outer surface of lower straighttube reaches predetermined temperature value, the temperature that goes up straight tube and bend pipe surface simultaneously a little more than or equal the temperature of the outer surface of lower straighttube; Now temperature inductor is carried instruction to temperature control valve (TCV) and heating furnace respectively.Open temperature control valve (TCV), make the steam in lower straighttube pass through temperature control valve (TCV), arrive condenser pipe, form aqueous water, flow back in heating furnace; Heating furnace switches to discontinuity work or quits work.
As preferably, the two ends of bend pipe are all evenly provided with 4 La Erka; One end that upper straight tube and lower straighttube are connected with bend pipe is all provided with a circle groove; Groove matches with La Erka.
The utility model is all evenly provided with 4 La Erka at the two ends of bend pipe, forms female joint with the bend pipe of La Erka; One end of upper straight tube and lower straighttube is provided with groove, is with reeded upper straight tube and lower straighttube to form male joint; Both form earrings is jointly snap joint, not only makes bend pipe be combined with upper straight tube and lower straighttube tightr, and does not need use instrument just can carry out dismounting, conveniently radiant tube tank interior is cleaned.
As preferably, the outer surface of bend pipe, upper straight tube and lower straighttube is all provided with radiating fin.
The utility model bend pipe, on the outer surface of straight tube and lower straighttube be all provided with radiating fin, promote the heat radiation of radiant tube body, improve heat radiation.
The utility model is compared with existing radiant tube, and beneficial effect is: (1) does not need to use burning gases, non-exhaust emission; (2) energy-conserving and environment-protective; (3) heating cost is low.
