Description
Technical field
The utility model relates to a kind of spiral sulfur trioxide electric heater.
Background technology
At present, in the processing of sodium hydrosulfite (sodium dithionite), need to use sulfur trioxide to carry out oxidation and vulcanizing treatment synthesis, adding man-hour, need to heat sulfur trioxide, what prior art adopted is that heat exchanger carries out sulfur trioxide heat temperature raising, but the heat exchange efficiency of heat exchanger is lower, the heating that heats up fast can not be accomplished, conventional art generally adopts repeatedly heat exchange, just temperature is improved with increase heat exchange number of times, although such method can accomplish that intensification is heated to expection processing problems, but it is very large to consume energy, the speed of heat temperature raising is slower, operating efficiency is very low, also the production efficiency of sodium hydrosulfite (sodium dithionite) has been affected indirectly, further, repeatedly heat exchange also can affect the degree of purity of sulfur trioxide.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of spiral sulfur trioxide electric heater.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of spiral sulfur trioxide electric heater, comprise heating tank, the upper side wall of described heating tank is provided with the interface of giving vent to anger of sulfur trioxide, the lower wall of heating tank is provided with the intake interface of a pair sulfur trioxide, the top of this heating tank is provided with seal disc, the described seal disc of institute vertically fixedly mounts screw type one group of heating tube, this group heating tube upper end is provided with patchboard, the bringing-up section that described heating tube enters described heating tank inside is fixed on heating tank top tank structure in the shape of a spiral, the extension of heating tube is that rectilinear tubes is fixed on described seal disc and patchboard.
The arrangement of heating tube boundling is fixed by locking nut by described patchboard, described heating tube sealing is fixed by insulation ring flange by described seal disc, and being provided with heat radiation chamber between sealing dish and patchboard, the two ends of this heat radiation chamber are respectively equipped with cold air inlet pipe and cool out pipe; The upper end of described patchboard is also provided with the wiring chamber connecing electricity for heating tube, and these wire connection cavity indoor have power connection end mouth; The bottom of described heating tank is provided with exhaust tube, and described exhaust tube is connected and installed with vacuum pumping pump.
Compared with prior art, the utility model have employed the heating tube of spiral design as heating element heater, give sulfur trioxide in heating tank directly to heat, compare in-line arrangement heating tube and substantially increase heating surface (area) (HS, the temperature of sulfur trioxide in tank can be improved quickly and efficiently; The insulation ring flange of the sealing adopted, while the degree of purity ensureing the sulfur trioxide in tank, also can ensure that internal temperature does not run off, and ensure that the high efficiency of heating; The heat radiation chamber adopted can ensure that the temperature at the position do not worked of heating tube and the spot temperature of work keep balance, prevents the overheated damage causing heating tube in position do not worked; And adopt vacuum pumping pump when preheating, will can be evacuated in whole tank, so just ensure sulfur trioxide degree of purity after entering, total is simple, is easy to realize, and the efficiency of heating surface is high, increases work efficiency, and enhances productivity, and is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the spiral sulfur trioxide electric heater that the utility model proposes, comprises heating tank 1, and the upper side wall of heating tank is provided with the interface 2 of giving vent to anger of sulfur trioxide, and the lower wall of heating tank is provided with the intake interface 3 of a pair sulfur trioxide.The connecting interface of interface 2 and intake interface 3 of giving vent to anger all installs air pipe flange dish, prevents gas leakage.
The top of heating tank is provided with seal disc 4, seal disc 4 vertically fixedly mounts screw type one group of heating tube 5, this group heating tube upper end is provided with patchboard 6, the bringing-up section that heating tube 5 enters heating tank 1 inside is fixed on heating tank top tank structure in the shape of a spiral, and the extension of heating tube is that rectilinear tubes is fixed on described seal disc 4 and patchboard 6.
The arrangement of heating tube 5 boundling is fixed by locking nut 7 by patchboard 6.Seal disc 4, as the end cap of heating tank, has loose structure, facilitates heating tube to insert, and use locking nut to be fixed, and patchboard 6 is also similar disk-like structure, and heating tube can be allowed to insert after inserting.
Heating tube 5 seals fixing by insulation ring flange 8 by seal disc 4, and is provided with heat radiation chamber 9 between sealing dish 4 and patchboard 6, and the two ends of this heat radiation chamber 9 are respectively equipped with cold air inlet pipe 10 and cold air goes out pipe 11.
The upper end of patchboard 6 is also provided with the wiring chamber 12 connecing electricity for heating tube 5, and these wire connection cavity indoor have power connection end mouth 13.The bottom of heating tank 1 is provided with exhaust tube 14, exhaust tube is connected and installed with vacuum pumping pump 15.Wiring chamber 12 is the wiring construction of conventional art, and the inside has the components and parts of wiring, comprising starter, driver, transformer, Automatic Protection Switching, control panel etc.
In the utility model, before using, all interfaces are all closed, as intake interface, the interfaces such as interface of giving vent to anger; And use vacuum pumping pump to carry out vacuumizing process, after completing application of vacuum, sulfur trioxide air inlet source is connected at use intake interface, interface of giving vent to anger connects outgoing gas connection tube, wiring chamber 12 is energized, and powers to heating tube, and heating tube carries out sulfur trioxide in heating tank, sulfur trioxide completes heating in the flow direction from the bottom up, can use after giving vent to anger.And wherein when heating work, the heating tube of spiral design is as heating element heater, giving sulfur trioxide in heating tank directly heats, and compares in-line arrangement heating tube and substantially increases heating surface (area) (HS.The heating tube 5 that the indoor cooperation going out pipe by both sides cold air inlet pipe and cold air of heat dissipation cavity ensures is inserted into the part in heating tank and the portion temperature be not inserted in heating tank keeps balance, so just can stop the temperature difference that heating tube produces, and then have impact on the service life of whole heating tube.The protection of this part is not accomplished in the use of heating tube of the prior art yet.
Above-described embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
