Drainage device

This product using Archimedes law, lever principle and filled with liquid containers of internal pressure the principle of uniform, rely on the float in oil medium buoyancy difference and make float up and down movement, and through the force of amplification mechanism will increase the buoyancy of float get sent to enlarge, this as power drain valve control of the open, to cut water and oil sealing purpose, achieve automatic water cut.

1. Overview

As the national petroleum chemical industry the development of industry and increase of oil tanks, safety protection and environmental management problem increasingly, past oil chemical enterprise in storage tanks in the process of dehydration, generally USES artificial site see work of manual valves dehydration, visual dehydration with oil to close the valve, such already cause oil waste and pollution of the environment, will also run for dehydration caused the oil fire, the domestic several major oil tank area fire accident and oil tank artificial dehydration run on oil, to the state and people's life and property caused heavy loss. Therefore, my company now according to the need of petrochemical industry tanks dehydration, in the original technology developed based on the design of a new generation of products "HQS type automatic cut the water tank" (patent no. : 200520096029.0).

This product corrosion resistance is strong, and large displacement, return oil speed with reasonable design, simple structure and convenient operation, safe and reliable. This product in petroleum, chemical industry use can replace artificial middle cut water storage tank, has realized automatic water cut, solve the water ran the man-made cut oil, oil products and to reduce the waste and environmental pollution.

The use of this product is greatly reduced operators' labor intensity and artificial cut water hydrogen sulphide poisoning. So the use of this product promotion can satisfy the petrochemical system of GuanDaoHua AnGou emissions, the requirements, avoid disorderly emissions, the improvement of ecological environment, and accord with the national environmental protection request.

This product conforms GB50074-2002 "oil depot" code for design and GB50160-92 "petroleum chemical enterprise of the code for fire protection design rules, for all kinds of oil tank and liquid chemical material tank of water cut.


2. Working principle

This product using Archimedes law, lever principle and filled with liquid containers of internal pressure the principle of uniform, rely on the float in oil medium buoyancy difference and make float up and down movement, and through the force of amplification mechanism will increase the buoyancy of float get sent to enlarge, this as power drain valve control of the open, to cut water and oil sealing purpose, achieve automatic water cut.

This product USES no back pressure special design structure, make open or close the valve more flexible, can also according to the customer's need to implement system of remote automatic monitoring, make water tank, cut automatic management.


3. Product technical features

1. The perfect using Archimedes law and leveraging the amplification principle, will produce oil and water density difference the buoyancy of poor cleverly into power, realize the don't need energy to automatically cut water;

2. Oil and water into the cut after the water can be separated, the more oil can quickly back into the oil tank, when the water level in the cut to a certain height, the valve core open drainage, water levels to a certain height, the valve core automatically shut off;

3. Cut after water, water cut is always maintain a certain height in the water level, form to be automatic water seal; The two sealing of dehydration, ensure no oil leaked;

4. This product USES no back pressure without pressure valves, lever first drive needle valve mobile, make internal and external pressure valve core consistent, lever continue to move, the needle valves and valve core very flexible together began to cut water, in and out of the oil can normal cut water;

5. Counterweight was fixed on the float internal, when oil density have change, do not need to adjust the balance;

6. Cut the water has been with the drain valve and clean water cut is not need to cut apart water purifier, cleaning a cut water vessels only need ten minutes to finish;

7. Cut the water drain can be arbitrary put around, there are 360 ° of drainage directions to choose from;

8. Small size, low foundation of tank bottom of tank adaptability is strong;

9. According to user's special requirements, and meet the different working conditions cut water requirements.


4. Technology parameters

2. Working temperature: 0 -80

3. Nominal cut water: 5 m 3 / h, 10 m 3 / h, 15 m 3 / h, 20 m 3 / h, 30 m 3 / h, 60 m 3 / h

4. Cut water oil content: more than 80 PPM

5. Work medium: type A, type B light crude oil or heavy fuel oil

6. Applicable medium density ρ 20: more than 960 kg/m 3

7. The steam pressure: 0.1 MPa than P than 1.0 MPa

       2.Notes

1. Cut in oil tank pipe should be no direct elbow pipe, valve is a gate valve and so on direct connectivity to the valve, cut the water directly with cans of root valves level connection, if is carried, should be installed return hose, installation, see figure 3.

2. To make the cut of oil in the water more timely return to oil tank, should guarantee the cans of root valves and cut the connecting line of water without up elbow or other among some ups and downs.

3. Crude oil and heavy oil and north cold region to deal with cans of root valve, filter, cut water device, connection tube should increase the steam and hot water circulating, electric tracing band and heating measures and, when necessary, can add the thermostat;

4. According to the tank with impurity medium choice of the filter, or whether the need to install filters.

5. Cut the water remote monitoring system of see the single.

 

 

8. Guide to use

1. Cut the water after the completion of installation, should check the whole installation system is correct, the joint to tighten bolts, and then open the root valves make stand oil tank of water inside people cut the water inside, there is a water purifier gases from the top eduction, wait for gas row after cutting the water on top after emptying, cut the water began to normal water cut. Cut the water ends, when oil tank appear again in water cut water settlement device automatic recovery cut water, round and round.

2. Crude oil and heavy oil and cold areas oil, to be linked with hot insulation device, improve the liquidity of oil. When operating first open the storage tank connected valve and cut the water purifier manual valve, then open the steam valve, temperature control at 90 ; About 15 minutes after the water cut to work, then will the temperature control in 45  65 ; After the water cut, such as to close the valve to close first pot root steam connected valve, stop heating water containers to avoid cut excessively high temperature Bie pressure and accidents.

 

9. Maintenance

1. The main products for stainless steel parts, not wearing parts, sealing washer for fluorine rubber and ptfe, with oil resistance, corrosion resistance, anti-aging characteristic;

2. Should be based on the medium and field use and regular cleaning of automatic cutting water vessels, to ensure the normal use of water cut, are generally once a year;

3. Cut the water out of balance, trimming has good set-up, don't remove and adjust at will, special circumstances should please this company specialized personnel deployment, to avoid the failure caused by water cut.

4. Troubleshooting:

Serial no.

2.Temperature is not

enough, medium solidification

3.inside of Drainage device have air

1.Find out the reason, and open the relevant valves

2.Increasing the steam temperature

3.Open the manual row eliminate air valves

2

After the water cut with a small amount of the water out and still with oil

1. Trash material in Automatic Drainage Device

2. too much sediment

1.Remove debris

2.Clean the device

3

The flange

seal leakage at the exit

1.Sealing gasket deformation

2.Bolts force does not even

1.Replace the seal gasket

2.The bolt on to evenly

4

In the process of water cut with oil

1.Oil has emulsification phenomenon

2.density of oil is too much
