Abstract
The utility model discloses a N - vinyl pyrrolidone distillation level gauge on the raffinate groove for the heavy ends, the level gauge for the hot level gauge of steam type companion, the level gauge divide into level gauge body and steam jacket, the level gauge body links to each other with the raffinate groove through the pipeline and is used for showing the liquid level, steam jacket and level gauge body between be equipped with the clearance, steam jacket lower part intercommunication has the steam pipe, steam jacket upper portion intercommunication has the blast pipe, level gauge body bottom be connected with the delivery pipe, the steam pipe on be equipped with first valve, the blast pipe on be equipped with the second valve, the delivery pipe on be equipped with the third valve, the steam pipe on the delivery pipe that is equipped with between bleeder and third valve and the level gauge body on the anterior steam pipe of first valve communicate, the bleeder on be equipped with four valves. Compared with the prior art, the beneficial effects of the utility model are that: it is obvious to remove the scar effect, and the level gauge blocks up and reduces, and extension level gauge life improves economic benefits indirectly.
Description
Technical field
The utility model relates to the liquid level gauge on the raffinate groove of a kind of NVP distillation heavy constituent.
Background technology
NVP (NVP) has the pyrrolidone (2-P), KOH and a small amount of raffinate that forms of NVP (NVP) that distills when distilling heavy constituent, raffinate is stored in raffinate groove, raffinate groove is provided with the amount that liquid level gauge is used for showing raffinate, now in order to can more environment be adapted to, usual employing heating type liquid level gauge, and steam-type accompanies hot liquid level gauge to be conventional one; Above-mentioned raffinate generally because of comparing thickness, can make inwall scab, therefore causing liquid level gauge to block under long-time companion's enthusiasm condition, causes liquid level gauge to show inaccurate.
Utility model content
The purpose of this utility model to provide the liquid level gauge on the raffinate groove of a kind of NVP distillation heavy constituent.
For achieving the above object, the utility model is implemented according to following technical scheme: the liquid level gauge on a kind of raffinate groove of NVP distillation heavy constituent, described liquid level is counted steam-type and is accompanied hot liquid level gauge, described steam-type accompanies hot liquid level gauge to comprise liquid level gauge body and the steam jacket of chuck outside it, described liquid level gauge body is connected for showing liquid level by pipeline with raffinate groove, gap is provided with between described steam jacket and liquid level gauge body, described steam jacket bottom is communicated with steam pipe, described steam jacket top is communicated with gas outlet, described liquid level gauge body bottom portion is connected with delivery pipe, described steam pipe is provided with the first valve, described gas outlet is provided with the second valve, described delivery pipe is provided with the 3rd valve, on described steam pipe, the steam pipe of the first valve front portion is provided with take-off pipe and is communicated with the delivery pipe between the 3rd valve and liquid level gauge body, described take-off pipe is provided with the 4th valve.
Further, the first described valve, the second valve, the 3rd valve and the 4th valve are needle valve.
When reality uses, when raffinate groove is vacant, the first valve, the second valve, the 3rd valve can be closed, then open the 4th valve, by steam blowing liquid level gauge inner body wall, wash away and scab, make liquid level gauge elongated for serviceable life, reduce blocking 2.
Compared with prior art, the beneficial effects of the utility model are: except scar successful, and liquid level gauge blocking reduces, and extends liquid level gauge serviceable life, indirectly increases economic efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in the illustrative examples of this utility model and explanation, but not as to restriction of the present utility model.
Liquid level gauge on the raffinate groove of a kind of NVP distillation heavy constituent as shown in Figure 1, described liquid level is counted steam-type and is accompanied hot liquid level gauge, described steam-type accompanies hot liquid level gauge 2 to comprise liquid level gauge body 21 and the steam jacket 22 of chuck outside it, described liquid level gauge body 21 is connected for showing liquid level by pipeline with raffinate groove 1, gap is provided with between described steam jacket 22 and liquid level gauge body 21, described steam jacket 22 bottom is communicated with steam pipe 3, described steam jacket 22 top is communicated with gas outlet 4, delivery pipe 5 is connected with bottom described liquid level gauge body 21, described steam pipe 3 is provided with the first valve 6, described gas outlet 4 is provided with the second valve 7, described delivery pipe 5 is provided with the 3rd valve 8, on described steam pipe 3, the steam pipe 3 of the first valve 6 front portion is provided with take-off pipe 9 and is communicated with the delivery pipe 5 between the 3rd valve 8 and liquid level gauge body 21, described take-off pipe 9 is provided with the 4th valve 10.First valve 6, second valve 7, the 3rd valve 8 and the 4th valve 10 are needle valve.
When reality uses, when raffinate pipe is vacant, the first valve 6, second valve 7, the 3rd valve 8 can be closed, then open the 4th valve 10, by steam blowing liquid level gauge body 21 inwall, wash away and scab, make liquid level gauge elongated for serviceable life, reduce blocking.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
Claims (2)
