Description
Technical field
The utility model relates to a kind of cleaning device, is specifically related to a kind of cleaning device of shell-and-tube heat exchanger.
Background technology
Shell-and-tube heat exchanger is the visual plant of water-cooled refrigeration unit, power station and industry cooling, heat exchange and since in the shell-and-tube heat exchanger tube side recirculated water in turnover constantly, under the prerequisite that the cleannes of recirculated water can't guarantee; If heat exchanging organ pipe journey such as does not regularly clean at reason; Iron rust, mud will deposit, and cause the dirt of heat exchanger tube tube side or dirtiness resistance that microorganism is caused heat exchanger to increase, and cause that entire thermal resistance enlarges markedly; Cause the heat exchange effect to descend; The heat exchange temperature raises, and energy consumption increases, especially severe cause the heat exchanger incapacitation.Secondly dirt also has deposited phenomenon, and sedimental characteristic is changed, and the deposition of dirt can cause that all deposit becomes more tough and tensile in time, more is difficult to degrade usually.According to estimates, on annual China refrigeration unit condenser and other industries with shell-and-tube heat exchanger since the caused economic loss of influence of dirt up to tens yuan.
Traditional cleaning way consumes resources is bigger, needs the utensil of special messenger and specialty.Two kinds of artificial cleaning of its cleaning way branch and chemical agent scale removal.The modal mode of artificial cleaning is exactly " shutdown pickling ", and shutting down pickling needs frequent dismounting equipment, and the pickling heat exchanger tube not only causes personnel's labor service expenditure, also need shut down or increase guest machine; Chemical cleaning needs cubic metre of earth medicament regularly, the possible corrosion pipeline of medicament, and not environmental protection, dangerous, and heat transmission equipment is contaminated again after 24 hours, and efficient reduces once more.Old-fashioned ball cleaning apparatus glueballs all is from Rubber ball pump, to send, and gets in the shell-and-tube heat exchanger, and this just might cause glueballs by the quick runner mechanical failure, causes the rate of recovery not high.
Summary of the invention
To above-mentioned technical problem, the utility model provides a kind of cleaning device of shell-and-tube heat exchanger, and it need not to adopt the artificial mechanical failure of cleaning, can avoid rotating wash bowl again, and cleaning performance is good, the rate of recovery of rotating wash bowl high.
The technical scheme that realizes the utility model is following:
A kind of cleaning device of shell-and-tube heat exchanger; This cleaning device comprises container; Be provided with in the container and have the lateral isolation plate that ball is imported and exported; Receive ball chamber and ball storage chamber in order to container is separated into, the upper end of container is provided with connection and receives the bulb that goes out that return of serve pipe, the lower end of ball chamber are provided with connection ball storage chamber, and this cleaning device comprises that also water inlet pipe is communicated with the circulating pump of receiving ball chamber, outlet pipe connection ball storage chamber.
The indoor screen pack that the liquid that gets into the circulating pump water inlet pipe is filtered that is provided with of said receipts ball.Screen pack can prevent that circulating pump from sucking rotating wash bowl in the circulating pump.
The middle part of said lateral isolation plate is the guide structure to lower recess, and said ball is imported and exported and is positioned at the recess bottom, and the rotating wash bowl of being convenient to receive in the ball chamber falls into ball storage chamber smoothly.
The below that ball is imported and exported on the said lateral isolation plate is provided with the seal cover that ball is carried out capping, and the sealing lid is movably connected in the below that ball is imported and exported; Under the pressure of water, seal cover is imported and exported sealing with ball, and the rotating wash bowl of receiving in the ball chamber can not fall into ball storage chamber, and the rotating wash bowl in the ball storage chamber is fed into out in the bulb.
Said return of serve pipe is provided with the rotating wash bowl ball collecting device, and it comprises the receipts global shell, is arranged on the screen pack of receiving in the global shell, and screen pack is provided with the return of serve mouth that supplies rotating wash bowl to pass through, and the return of serve end of said return of serve pipe is arranged in this return of serve mouth.Rotating wash bowl just gets into the rotating wash bowl ball collecting device through behind the pipeline that was cleaned, and under the effect of rotating wash bowl ball collecting device, rotating wash bowl gets in the return of serve pipe, and is back to receipts ball chamber.
Saidly go out bulb and be provided with the check valve that prevents that rotating wash bowl from refunding.
Rotating wash bowl in the utility model need not pass through delivery pump; Avoided rotating wash bowl issuable mechanical wear in pump; And the effect of circulating pump is to deliver to the ball storage chamber of receiving below the ball chamber from receiving to draw water in the ball chamber in this cleaning device, utilizes the pressure of moment, will receive the seal cover closure between ball chamber and the ball storage chamber on the one hand; The rotating wash bowl that will drop down onto on the one hand the ball storage chamber below pours out bulb and sends in the tube side of heat exchanger; Tube side is cleaned, get back to from the return of serve pipe again and receive the ball chamber rate of recovery of rotating wash bowl >=96%.After using this cleaning device, heat exchanger tube side inwall is in clean conditions for a long time, eliminates the corrosion root, prolongs unit service life, and heat exchanger can be in best heat exchange state, and heat exchange efficiency is high; It can be as required regularly, regular heat exchanging organ pipe journey cleans, the energy resource consumption that makes equipment such as refrigeration unit practice thrift 10%-40% has reduced the unit operation expense; Exempted the expense of unpicking and washing heat exchange equipment simultaneously, economic loss and the inconvenience of having avoided conventional clean to cause are for the client creates higher economic benefit.
