Abstract
The invention discloses a method for cleaning salt depositions on a saline lake mining brine pump, which comprises the following steps of: moving the brine pump needing salt deposition cleaning to a platform in a pump cleaning pool filled with fresh water; starting a driving motor of the brine pump in a variable frequency speed control mode to ensure that the brine pump runs at a low speed for 1 to 3 minutes, wherein the running rotating speed is based on that the fresh water in a water outlet pipe of the brine pump does not flow out of the mouth of the pipe; cleaning the salt depositions in a pump flow passage; or upward hoisting a water sucking mouth end of a water inlet pipe of the brine pump to ensure that a water sucking mouth of the water inlet pipe faces upward; infusing external fresh water into the brine pump through the water inlet pipe; starting the driving motor of the brine pump in the variable frequency speed control mode to ensure that the brine pump runs at a low speed for 1 to 3 minutes, wherein the running rotating speed is based on that the fresh water in the water outlet pipe of the brine pump does not flow out of the mouth of the pipe; and cleaning the salt depositions in the pump flow passage. The method for cleaning the salt depositions can save the investments for laying pipelines and other auxiliary equipment for cleaning the salt depositions and reduce the fresh water consumption, has simple operation, high efficiency and low energy consumption, and can reduce operators and alleviate the labor intensity for the operators.
Description
Technical field
The present invention relates to a kind of method of cleaning salt depositions on saline lake mining brine pump, especially relate in a kind of salt lake bittern course of conveying the method for cleaning of brine pump salt crust.
Background technique
The main task of salt lake bittern exploitation is to adopt halogen and defeated halogen.Because bittern is the salt solution that high concentration contains the number of chemical component, wherein one or more salinities reach capacity, so in adopting halogen or defeated halogen process, the mobile and stirring of saturated bittern can make adopts defeated halogen equipment (mainly being brine pump) and generation corrosion of bittern contact position and salt crust; Again because the temperature variation of bittern or adopt in the defeated halogen process of halogen, flowing and stirring of saturated bittern, have young partial crystallization and go out and be attached to the surface that equipment contacts with bittern, crystal constantly growth can cause the serious salt crust of equipment and reduce effect, in addition can make adopt, defeated halogen work can not move.
Take place for stopping this type of situation, in the exploitation of the salt lake of China, the method for trying out many anti-salt crusts is as the anti-salt crust method of chemistry, ultrasound, static, magnetic force method etc.Because the inhibitor of the anti-salt crust method of chemistry costs an arm and a leg, and contains certain toxicity, therefore application is restricted.And ultrasound, static, magnetic force method be because of the equipment complexity, and power consumption is adopted more greatly and seldom.
At present, adopt of producer adds the method that fresh water prevents salt crust more both at home and abroad, and comparatively speaking, this method has advantages such as cost is lower, and manufacturing equipment is simple.Having under the situation of more abundant outside fresh water, general employing face of land fresh water pipeline will be with to press in the fresh water injection water pump or by pipeline and injection point and be added to pump sump mouth place, utilize the suction negative pressure of water pump to mix suction, owing to bittern is watered down, so in adopting defeated halogen equipment, can prevent salt crust; The shortcoming of this method is that construction investment is big, and the fresh water of consumption is many, and cost of production is still higher.And under the situation of no outside fresh water, then adopt tank car to transport fresh water to water tank, utilize the fresh water in the water tank that out-of-work brine pump is soaked clear salt, the advantage of this method is that fresh water consumption is few, and shortcoming is to prevent salt crust, grows (according to the difference in season and soak the clear salt time, salt crust soak time difference, about 5 ~ 12 hours), clear salt workload is big, and the reserve position number of brine pump needs more.
Another kind prevents that the method for brine pump water passage surface salt crust from being, in the brine pump manufacture process, adopt phenolic sand molding technology or/and in methods such as overcurrent position plastic-blastings, improve pump water passage surface degree of finish, the shortcoming of these methods is, can only delay the time of salt crust, can not solve the salt crust problem up hill and dale, and can improve the manufacture cost of pump.
Summary of the invention
The objective of the invention is to overcome the defective of existing cleaning salt crust technology, provide a kind of simple to operate, cost is low, and the efficient height need not to increase power, the brine pump salt crust method for cleaning that energy consumption is low.
The objective of the invention is to be achieved through the following technical solutions:
When running to water flow, brine pump work only is the 45-55% of water pump rated flow, when needing the cleaning salt crust, the brine pump dislocation of needs being cleared up salt crust is in the washing on the platform in the pump pond of fresh water is housed, adopt frequency control way starting brine pump drive motor, made the brine pump low cruise 1 ~ 3 minute, the rotating speed of operation does not flow out the mouth of pipe with the fresh water in the brine pump outlet pipe and is as the criterion, and the salt crust in the pump runner is cleaned.
Perhaps, needs being cleared up the water sucking mouth end of the brine pump intake pipe of salt crust upwards slings, the water sucking mouth that makes intake pipe up, by intake pipe outside fresh water is injected in the brine pump again, adopt frequency control way starting brine pump drive motor then, made the brine pump low cruise 1 ~ 3 minute, the rotating speed of operation does not flow out the mouth of pipe with the fresh water in the brine pump outlet pipe and is as the criterion, and the salt crust in the pump runner is cleaned.
Brine pump low cruise 1 ~ 3 minute, after the salt crust in the brine pump runner is cleaned out, the rinse water in the brine pump runner is discharged, with the former working position of brine pump (or suction sleeve) involution, brine pump can proper functioning then.
When needing the cleaning salt crust, use the present invention's salt crust method for cleaning, can save investment, reduce fresh water consumption into cleaning salt crust tubing and other supplementary equipment; Simple to operate, the efficient height, brine pump low cruise 1 ~ 3 minute just can be cleaned out the salt crust in the pump runner; Can reduce operator, and alleviate labor intensity of operating personnel; Help protecting water resources, the protection environment.
