세정동작 중에는, 압축기(21)의 용량이 프루드수(Fr)에 기초하여 설정된다. 프루드수(Fr)는, 가스측 연락관(70) 내의 액체에 작용하는 중력에 대한 가스측 연락관(70)을 흐르는 가스냉매의 관성력 비를 나타낸다. 세정동작 중에는 프루드수(Fr)가 1보다 커지도록 압축기(21)의 용량이 설정되어, 가스측 연락관(70)을 흐르는 가스냉매의 관성력이 가스측 연락관(70) 내의 광물유나 이물질을 함유한 액체에 작용하는 중력보다 커진다. 이로써, 가스측 연락관(70) 중의 수직부분에서도, 광물유나 이물질을 함유한 액체가 가스냉매에 의해 밀어 올려진다. 이와 같이 하여, 기설 액측 연락관(60) 및 가스측 연락관(70)에 잔존하는 광물유 및 이물질이 회수된다. During the washing operation, the capacity of the compressor 21 is set based on the number of frauds Fr. Frude water Fr represents the ratio of the inertia force of the gas refrigerant flowing through the gas side communication tube 70 to the gravity acting on the liquid in the gas side communication tube 70. During the washing operation, the capacity of the compressor 21 is set so that the water Fr becomes larger than 1, and the inertial force of the gas refrigerant flowing through the gas side communication pipe 70 contains mineral oil or foreign matter in the gas side communication pipe 70. Greater than the gravity acting on the liquid. As a result, even in the vertical portion of the gas-side contact pipe 70, the liquid containing mineral oil and foreign matter is pushed up by the gas refrigerant. In this way, the mineral oil and foreign matter remaining in the existing liquid side communication pipe 60 and the gas side communication pipe 70 are recovered.

Refrigeration equipment

洗浄動作中には、圧縮機（２１）の容量がフルード数Ｆｒに基づいて設定される。フルード数Ｆｒは、ガス側連絡管（７０）内の液体に作用する重力に対するガス側連絡管（７０）を流れるガス冷媒の慣性力の比を表す。洗浄動作中にはフルード数Ｆｒが１より大きくなるように圧縮機（２１）の容量が設定され、ガス側連絡管（７０）を流れるガス冷媒の慣性力がガス側連絡管（７０）内の鉱油や異物を含んだ液体に作用する重力よりも大きくなる。このため、ガス側連絡管（７０）のうちの鉛直部分においても、鉱油や異物を含んだ液体がガス冷媒によって押し上げられる。このようにして、既設の液側連絡管（６０）及びガス側連絡管（７０）に残存する鉱油及び異物が回収される。 During the cleaning operation, the capacity of the compressor (21) is set based on the fluid number Fr. The Froude number Fr represents the ratio of the inertial force of the gas refrigerant flowing through the gas side communication pipe (70) to the gravity acting on the liquid in the gas side communication pipe (70). During the cleaning operation, the capacity of the compressor (21) is set so that the fluid number Fr is greater than 1, and the inertial force of the gas refrigerant flowing through the gas side communication pipe (70) is increased in the gas side communication pipe (70). It becomes larger than the gravity acting on the liquid containing mineral oil and foreign matters. For this reason, also in the vertical part of the gas side communication pipe (70), the liquid containing mineral oil and foreign matters is pushed up by the gas refrigerant. In this way, the mineral oil and foreign matter remaining in the existing liquid side communication pipe (60) and gas side communication pipe (70) are recovered.

Method of purging heat exchanger tubes with fluidic agent and device for its implementation

FIELD: heating. SUBSTANCE: invention deals with a method of purging heat exchanger tubes with a fluidic agent and a device for the proposed method implementation. Under the proposed purging method a jet nozzle is put against the heat exchanger tube and a flux of air containing the fluidic agent is blown through the tube. The proposed method specificity consists in the jet nozzle with its outlet throughhole being not inserted inside the tube but tightly pressed against the tube end butt side with a thrust surface surrounding the outlet throughhole. The design solution typical of the jet device proposed for the method implementation is that of it being equipped with a jet nozzle whose outlet throughhole is surrounded by a thrust surface positioned within the hole plane and interacting with the butt side of the tune being purged, the outlet throughhole cross-section area corresponding to the area of the inner cross-section of the tube being purged. With the help of the device jet nozzle a flux of air containing the fluidic agent is to be blown through the heat exchanger tube having an inner diametre. The jet nozzle is designed to enable connection to a supply hose therethrough the fluidic agent flux is delivered and has a supply channel arranged in it therethrough the fluidic agent flux may flow. The jet nozzle design is basically as follows: the jet nozzle contains a housing whose first end is positioned as opposed to the second one, the two ends limiting the flow channel that stretches between the two ends. The first end has an inlet throughhole arranged in it therethrough the fluidic agent flux may be delivered from the supply hose; the first end has an outlet throughhole arranged in it therethrough the fluidic agent flux may be discharged from the nozzle. The flow channel has its first diametre within the inlet throughhole zone and its second diametre - within the outlet throughhole zone. The second diametre corresponds to the heat exchanger tube inner diametre ...

Shower heat exchanger with clog-removable drain

A heat exchanger placed underneath an elevated tub or shower stall or under the bathroom floor includes a flat top heat conductive plate. The top plate is fastened to a flat lower plate, having a serpentine pattern with a shallow depth embedded into the top surface. When the top plate is fastened and sealed to the lower plate, the flow of the incoming cold water is contained within the confines of the serpentine lower plate of the heat exchanger. Heat is transferred from the grey waste water falling onto the top plate to preheat the incoming cold water flowing underneath the top plate in the serpentine conduit chamber of the lower plate in contact with a bottom surface of the top plate. The cold water is thereby preheated and used as a substitute for the incoming cold water that would be normally plumbed to the discharge shower head.

Method and device for largely dust-free cleaning of heating boilers

In the cleaning method, combustion residues deposited in the flow ducts for the flue gases are detached, with the combustion chamber sealed off from the outside, by means of cleaning brushes moving to and fro in the ducts, and simultaneously sucked off through a corresponding suction opening. The combustion chamber is sealed off from the outside by means of a cleaning device in the form of a cover which is to be inserted into the combustion door opening of a heating boiler to be cleaned and which has at least one longitudinal guide for a long-handled guide means of a cleaning brush. The cover expediently consists of an annular part, which can be inserted into a combustion door opening, and a guide plate which can be rotatably accommodated in the region of a partial annular cutout and which has a longitudinal guide for the long-handled guide means of the cleaning brush.

A kind of case tube heat exchanger

本发明涉及一种壳管换热器。其技术方案是：包括壳体、换热管、管板、污水入口、软化水出口、软化水入口和污水出口，所述壳体的内腔设有多组换热管，换热管的两端通过管板固定连接，壳体的一端设有污水入口和软化水出口，另一端设有软化水入口和污水出口，所述的软化水出口、换热管和软化水入口连通，所述的污水入口、壳体的内腔和污水出口连通；本发明解决了以前壳管式换热器无法彻底清洗的技术难题，解决了油田生产，工业污水和印染行业污水不能用换热器换热的难题，并且改善了换热器的换热效率，增加了换热器的使用寿命。

Modified asphalt melting equipment in prebaked anode production

本发明公开了一种预焙阳极生产中改质沥青熔化设备，涉及预焙阳极生产技术领域，包括：熔化箱；出料口，所述出料口连接于所述熔化箱的外壁；进气管，所述进气管设置于所述熔化箱的顶端；排气管，所述排气管连接于所述熔化箱的顶端且位于所述进气管的一侧。本发明通过设置预热机构，风机抽取熔化箱内的气体进入排气管进入过滤箱，外界空气通过进气管进入熔化箱，排气管内的气体通过预热箱时，排气管内的气体与进气管的外壁接触，从而对进气管内的空气进行加热，降低了热量的流失，且在气体在排气管内流动时，刷动环在进气管的外壁进行往复位移，对进气管的外壁进行刷动，防止杂质的堆积对热交换造成影响。

Device and method for removing build-up on measurement gauges

The present invention is directed to a device and method for removing build-up on such measurement gauges. The inventive device and method involve a movable scraper (50) that fits around a cylindrical shield (40) of a measurement gauge and continuously removes the build-up on the shield. Movement of the scraper is accomplished by a magnetic coupling between a magnetic core (52) attached to the scraper, which is inside a pipe (10) or other piece of equipment, and solenoids (32, 34) that are installed on the outside of the pipe. The device and method of the invention ensure instantaneously correct readings from the measurement gauge and improve control and operation strategies of heat exchanges, with significant economic advantages.
