The big flow high temperature high pressure oil of a kind of high-risk medium reaction kettle station
Technical field
The utility model relates to a kind of big flow HTHP sealing oil circulation and supervisory system that is applied to the high-risk medium reaction kettle sealing of chemical industry, specifically is a kind of big flow high temperature high pressure oil station to high-risk medium.
Background technique
The high low pressure Lubricating-oil Station is floated system by low pressure lubricating system and high pressure and is formed, and low pressure lubricating system is made up of vertical gear pump-unit, fuel tank, one-way valve, safety valve, pressure gauge, duplex filter, pressure relay, cooler, solenoid valve, pressure reduction relay etc.High-pressure system mainly contains compositions such as high-pressure plunger pump-unit, high-pressure overflow valve, one-way valve, pressure gauge with electric contact, pipe-line system.Domestic oil station is applied to some common high pressure occasions more, and application surface is restricted.Do not consider the subsequent use of oil circulating pump such as 1.; 2. do not consider external (generally the adopting oil pump to be built in the fuel tank) of oil circulating pump under the high-risk medium situation; 3. do not consider under the situation of high-risk medium, the nitrogen filled protection at oil station; 4. output flow is less and cooling is not enough.
The model utility content
The purpose of the utility model is to overcome the deficiency that existing conventional oil station exists, and at this a kind of big flow high temperature high pressure oil station that can be applicable to high-risk medium is provided.
The utility model is to realize like this; Construct the big flow high temperature high pressure oil of a kind of high-risk medium reaction kettle station; It is characterized in that: on base, be provided with two and be used to realize the external high-pressure high-flow pump of sealing oil circuit; Fuel tank integral body is placed on the base, and said fuel tank is connected through pipeline with two high-pressure high-flow pumps and leads to, and injects the isolated sealing oil of low-pressure nitrogen at the fuel tank top; Also be provided with the first-stage condenser that is installed on the return line on the base, fuel tank is provided with Pilot operated check valve, needle type valve and pneumatic diaphragm control valve.
Whole oily station system will concentrate to be arranged on the vacant lot, a place away from high-risk medium reaction kettle.Adopt two external high-pressure high-flow pumps (opens is equipped with) to realize the circulation of sealing oil.The upper strata is that the isolated sealing oil of low-pressure nitrogen is injected at the top in fuel tank.Adopt summer the condensed in two stages device to realize cooling, utilize winter heat traced pipeline to come heated sealant oil, guarantee that sealing oil is in only viscosity.Utilize Pilot operated check valve, exact scale needle type valve and pneumatic diaphragm control valve to come oily station of accurate control and the interior pressure reduction of high-risk medium reaction kettle, medium does not leak when guaranteeing the leakage of machine envelope, thus assurance equipment and personnel's safety
The advantage of the utility model is: through the use at this oil station, improved the safety that the machine envelope is used greatly, substituted external inlet system fully, practiced thrift substantial contribution.

Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed description:
The utility model provides the big flow high temperature high pressure oil of a kind of high-risk medium reaction kettle station at this; As shown in Figure 1: as on base 101, to be provided with two and to be used to realize the external high-pressure high-flow pump 102 of sealing oil circuit; Fuel tank 103 integral body are placed on the base 101, and said fuel tank 103 is connected logical with two high-pressure high-flow pumps 102 through pipeline 104.Inject the isolated sealing oil of low-pressure nitrogen at fuel tank 103 inner tops, also comprise on the base 101 being provided with first-stage condenser 105, fuel tank 103 is provided with Pilot operated check valve 106, needle type valve 107 and pneumatic diaphragm control valve 108.First-stage condenser 105 is installed on the return line, and first-stage condenser 105 front ends connect filter through pipeline, and the rear end is connected to fuel tank 103 through pipeline; The effect of condenser is to reduce the oil temperature, in condenser inside cooling coil is arranged, and cooling coil has the cooling water turnover, through heat exchange, reduces the oil temperature.Only there is condenser at common oil station at fuel tank internal, and this time the oil station is because be used in hot environment, and returning-oil temperature is higher, so fuel tank 103 built-in condensers are used as secondary condenser.Fuel tank 103 sides have steam tracing pipeline gateway 109
.
Whole oily station system will concentrate to be arranged on the vacant lot, a place away from high-risk medium reaction kettle.Adopt two external high-pressure high-flow pumps 102 (opens is equipped with) to realize the circulation of sealing oil.Top of the upper layer injects the isolated sealing oil of low-pressure nitrogen in fuel tank 103 (built-in secondary condenser).Adopt summer the condensed in two stages device to realize cooling, utilize winter heat traced pipeline to come heated sealant oil, guarantee that sealing oil is in only viscosity.Utilize Pilot operated check valve, exact scale needle type valve and pneumatic diaphragm control valve to come oily station of accurate control and the interior pressure reduction of high-risk medium reaction kettle, medium does not leak when guaranteeing the leakage of machine envelope, thus assurance equipment and personnel's safety.
Lubricant oil in the fuel tank is after filtering by being pumped into the mechanical seal chamber, and lubricated then machine envelope is taken away the high temperature in the chamber simultaneously, after filtering cooling, gets back to fuel tank.Owing to be high-risk medium, therefore set oil station pressure and be higher than pressure medium in the still, when pressure is low, forbid producing; With needle type valve, Pilot operated check valve, realize that the pressure reduction of pressure medium in oil station pressure and the still is constant by pneumatic diaphragm control valve, guarantee simultaneously when the machine envelope is leaked; Realize machine sealing chamber chamber pressurize; Prevent high-risk dielectric leakage to outside, the protection Environmental security guarantees personal security.
