Technical Field

[0001] The utility model relates to the technical field of water treatment agent production, in particular to a foam catcher with a condensation function. Background Art

[0002] The production of water treatment agents, such as hydroxyethylidene diphosphonic acid and ethylenediamine tetramethylenephosphonic acid, involves a vigorous reaction of raw materials, generating large amounts of gas and heat. These high-temperature gases, accompanied by vapor and droplets of raw materials, intermediates, or products, often overflow the reaction system in the form of a mist. While these components are valuable raw materials and products for commercial production, they are toxic and hazardous to the environment. While condensers are used to condense and recover most of the condensable vapors, or gas absorption equipment is used to absorb most of the gases (such as hydrogen chloride), these processes are subject to unsatisfactory kinetics.

[0003] In addition, in order to prevent these components from overflowing and affecting the health of operators, an induced draft system is usually set up in the production system. These induced draft systems extract volatile components together with the droplets produced during the gas bubbling process. If not treated, it will also be a waste of resources and environmental pollution. Utility Model Content

[0025] In this embodiment, flange connections are used between the lower head 1, condenser 2, suds trap 3, and upper head 4. The condenser tubes are covered with fins and placed within a rectangular (or square) chamber. The ends of the tubes connect to a coolant chamber, which is connected to the external cooling water system via a coolant inlet and outlet. Upper and lower connecting flanges are located above and below the rectangular (or square) chamber, respectively, and these two flanges are connected to the chamber through the housing.

[0026] Specifically, the upper end face of the connecting flange 28 of the condenser is fixedly connected to the foam catcher 3, and the foam catcher 3 includes a foam catcher lower connecting flange 31, and the upper end face of the foam catcher lower connecting flange 31 is fixedly connected to the foam catcher lower support plate 35, and the upper part of the foam catcher lower support plate 35 is installed with a foam catcher material cavity 32, and the upper part of the foam catcher material cavity 32 is fixedly installed with a foam catcher upper support plate 34, and the upper end face of the foam catcher upper support plate 34 is fixedly installed with a foam catcher upper connecting flange 36.

[0027] In this embodiment, the foam catching upper support plate 34 and the foam catching lower support plate 35 are manufactured integrally with the foam catcher 3.

[0028] Specifically, the foam catching material 33 is fixedly installed inside the foam catching material cavity 32 .

[0029] In this embodiment, the foam capturing material 33 is laid in multiple layers to fully capture foam.

[0030] Specifically, the lower head 1 includes a shell 11, a gas inlet pipe 14 is installed through the side end of the shell 11, a gas inlet port 13 is provided at the end of the gas inlet pipe 14 away from the shell 11, and a lower head connecting flange 12 is fixedly connected to the upper end surface of the shell 11.

[0031] In this embodiment, the condensable components in the high-temperature airflow are condensed into liquid after cooling by the coolant tubes 24 and the fin heat exchanger 25; under the agitation of the fin heat exchanger, the small droplets absorb the condensed liquid and become large droplets. These droplets and condensed liquid are captured by the fins and flow into the receiving chamber 15 of the lower head 1 under the action of gravity.

[0032] Specifically, the upper head 4 includes an upper head shell 41 , an exhaust gas outlet pipe 42 and a pressure relief hole 43 are fixedly mounted on the upper end surface of the upper head shell 41 , and an upper head connecting flange 44 is fixedly connected to the lower end surface of the upper head shell 41 .

Then the staff starts the equipment. During the operation of the equipment, the pressure relief hole 43 is closed. Under the action of the system induced draft fan, the gas foam from the workshop carries the high-temperature air flow through the gas inlet port 13 and the gas inlet pipe 14, diffuses into the condenser 2, and is cooled through the condensation tubes 24 and the fin heat exchanger 25. The condensable components in the high-temperature air flow are condensed into liquid; under the stirring of the fin heat exchanger 25, the mist The droplets absorb the condensed liquid and turn it into large droplets. These droplets and condensate are captured by the fins and flow into the liquid receiving chamber 15 of the lower head 1 under the action of gravity. The droplets that have not been captured in the condenser 2 enter the foam catcher 3 under the carry-over of the airflow, and the droplets are further captured by the foam catcher material. Under the action of gravity, the captured liquid flows downward through the condenser and into the liquid receiving chamber 15 of the lower head 1. All the condensed and captured liquids are collected in the liquid receiving chamber 15 and flow back to the liquid recovery system through the liquid reflux port. In the foam catcher, the purified gas is discharged from the equipment through the exhaust gas outlet 42 of the upper head under the action of the induced draft fan and enters the next treatment process.
