The device is characterized by being provided with a washing and recovery device consisting of a tank body, a regular packing distributor, a gas distributor, a spraying device, a liquid level meter, air inlets, an emptying pipe, an overflow pipe and a drainage valve, wherein the regular packing distributor is arranged on the upper section in the tank, and the gas distributor is arranged on the lower section in the tank; the spraying device is arranged above the regular packing distributor; each radial branch pipe of the gas distributor is communicated with each of a plurality of air inlets in the tank body, and a safety valve exhaust port and an emptying valve exhaust port of each liquid ammonia storage tank are communicated with the corresponding air inlets of the tank body through the unit emptying valves respectively; an overflow port is formed in the tank wall between the regular packing distributor and the spraying device, a drainage port is formed in the tank bottom, and the drainage port is communicated with the overflow pipe through the drainage valve; the liquid level meter is arranged on the tank wall, and an exhaust pipe is arranged on the top of the tank. The device has the advantages that the emptying gas is absorbed, washed and emptied through the device.
Description
Technical field:
Poisonous, harmful exhaust body (gas-gas ammonia soluble in water) recycling technology that the utility model relates to, particularly a kind of for the liquid ammonia storage tank washing and recycling device of dropping a hint.
Background technology:
Liquid ammonia storage tank drops a hint from two parts at present, the one: the safety device of liquid ammonia storage tank setting is safety valve, but when liquid ammonia storage tank pressure surpasses safety valve jumping up pressure, safety valve is opened automatically, pressure let out to safety valve pressure is set, but a large amount of being emitted in the air of the gas ammonia of liquid ammonia storage tank meeting pollutes environment, also can cause the generation of security incident.The 2nd: log off at liquid ammonia storage tank and to overhaul or pressure vessel when detecting, must be in the liquid ammonia storage tank venting of speeding of residue 0.1-0.2MPa directly to airborne release.The gas ammonia of this two parts emptying directly enters in the atmosphere contaminated environment, and the device of recovery is not arranged.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, provide a kind of for the liquid ammonia storage tank washing and recycling device of dropping a hint.
Scheme of the present utility model is: comprise storage tank safety valve, atmospheric valve, it is characterized in that: be provided with a washing and recycling device of being formed by tank body, structured packing distributor, gas distributor, spray equipment, liquid level gauge, air inlet, blow-down pipe, overflow pipe, draining valve, the structured packing distributor is fixedly mounted on the tank inner chamber epimere, and gas distributor is fixedly mounted on the tank inner chamber hypomere; Spray equipment is uniform several spouts of ring pipe nozzles down, and ring pipe is communicated with a jar outer source of the gas pipe by pipeline, and spray equipment is fixed on a jar interior structured packing distributor top; Gas distributor is several radially arm connections of ring Zhou Guanyu of uniform several pores, each radially arm respectively with corresponding orientation tank body on several air inlets be communicated with, safety valve exhaust outlet, the atmospheric valve exhaust outlet of each unit jar of several liquid ammonia storage tanks are communicated with the unit blow-down pipe respectively, and blow-down pipe another port, unit is communicated with the corresponding air inlet pipeline of tank body; Tank skin between structured packing distributor and the spray equipment is provided with overfall, overfall is communicated with the accident emergency pond by overflow pipe, the jar end, also be provided with a discharge outlet, discharge outlet is communicated with overflow pipe by a draining valve: be respectively arranged with through hole on structured packing distributor top, the tank skin at jar end and be communicated with the liquid level gauge upper and lower port, tank deck is provided with blast pipe.
Advantage of the present utility model is: the emptying after this device absorbs washing of dropping a hint is conducive to safety, environmental protection.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is structured packing distributor, gas distributor structural representation.
The specific embodiment:
The utility model comprises storage tank safety valve 8, atmospheric valve 9, it is characterized in that: be provided with a washing and recycling device of being formed by tank body 5, structured packing distributor 4, gas distributor 11, spray equipment 7, liquid level gauge 3, air inlet, blow-down pipe, overflow pipe 1, draining valve 2, structured packing distributor 4 is fixedly mounted on tank body 5 inner chamber epimeres, and gas distributor 11 is fixedly mounted on tank body 5 inner chamber hypomeres; Spray equipment 7 is uniform several spouts of ring pipe nozzles down, and ring pipe is communicated with a jar outer source of the gas pipe by pipeline, and spray equipment 7 is fixed on jar interior structured packing distributor 4 tops; Gas distributor 11 is several radially arm connections of ring Zhou Guanyu of uniform several pores, each radially arm 12 respectively with corresponding orientation tank body on several air inlets be communicated with, safety valve 8 exhaust outlets, atmospheric valve 9 exhaust outlets of each unit jar of several liquid ammonia storage tanks 10 are communicated with the unit blow-down pipe respectively, and blow-down pipe another port, unit is communicated with the corresponding air inlet pipeline of tank body; Tank skin between structured packing distributor 4 and the spray equipment 7 is provided with overfall, overfall is communicated with the accident emergency pond by overflow pipe 1, the jar end, also be provided with a discharge outlet, discharge outlet is communicated with overflow pipe 1 by a draining valve 2: be respectively arranged with through hole on structured packing distributor 4 tops, the tank skin at jar end and be communicated with liquid level gauge 3 upper and lower ports, tank deck is provided with blast pipe 6.
Structured packing distributor 4 is chemical industry working standard spare, is to be full of porcelain grain or irregular lattice plate in a framework, and effect is that forced draft fully contacts with water, reaches better absorption.
Safety valve 8, the atmospheric valve 9 of several liquid ammonia storage tanks 10 are inserted in the absorber washer by the unit blow-down pipe, control the liquid level (can watch by liquid level gauge) of absorber washer at ordinary times to overflow pipe 1 overflow place, keep gas distributor 11, structured packing distributor 4 in the absorber washer to duck in drink, open a water spray and absorb the gas ammonia that washs in dropping a hint when liquid ammonia storage tank 10 emptying, the water after the absorption enters in the accident emergency pond by overflow pipe 1.
If safety valve 8 exhaust outlets, atmospheric valve 9 exhaust outlets are lower than the retracting device overfall, then the unit blow-down pipe will raise earlier, is higher than to be that reverse U shape is downward to be communicated with the retracting device air inlet behind the overfall again, can not allow water flood the unit blow-down pipe fully.
