Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
in the figure: 1. a second water-sealed tank, 2, a micro-positive pressure nitrogen storage tank, 3, a raw material tank, 4, a condenser, 5, a double-layer breathing water-sealed tank, 6, a one-way valve, 7, a self-supporting pressure regulating valve, 8, a connector, 9 gas phase pipes, 10 liquid seals, 11 fixing frames and 12 partition plates
The specific implementation mode is as follows:
for the purpose of enhancing the understanding of the present invention, the following detailed description is made with reference to the accompanying drawings.
Example 1: referring to fig. 1, a pressure-fired nitrogen protection system for chemical storage tank, protection system includes and feed tank 3, pressure-fired nitrogen storage tank 2, double-deck breathing formula water sealed tank 5 and second water sealed tank 1, the double-deck breathing formula water sealed tank of pipe connection is passed through at the top of feed tank, pressure-fired nitrogen storage tank 2 and second water sealed tank 1 are connected gradually through the pipeline to the top side of feed tank. According to the scheme, firstly, resources are saved, secondly, a raw material tank is protected by nitrogen to play an explosion-proof role, a condenser 4 is arranged at the top of the raw material tank 3 and is connected with a double-layer breathing type water-sealed tank 5 through a pipeline, and a solvent brought out when the raw material tank is out is captured by the condenser and returns to the raw material tank again, so that the solvent can be reused, the resources are saved, and the cost is reduced; when the condenser trouble, the solvent volatilizees to the atmosphere in, causes the pollution easily, consequently double-deck breathing type water sealed tank 5 plays sealed effect, and isolated solvent prevents to volatilize to the air in, wherein is provided with check valve 6 on the pipeline between head tank 3 and the pressure-fired nitrogen gas storage tank 2, and this check valve can only guarantee that nitrogen gas gets into the head tank, avoids the solvent in the head tank to volatilize to the pipeline in, be provided with self-supporting air-vent valve 7 on the pipeline that the side of pressure-fired nitrogen gas storage tank is connected, in this scheme, the second water sealed tank plays the safety protection effect, and when the formula of relying on oneself air-vent valve breaks down and can not normal operating, pressure is greater than 1000pa in the nitrogen gas storage tank, and nitrogen gas pressurized gets into the rear end water sealed tank, volatilizees out in the liquid level, lets out nitrogen gas tank unnecessary pressure simultaneously, keeps whole system to be.
