Description

Technical Field

[0001] The utility model relates to the field of condensers, in particular to a 2-chloropropionyl chloride reflux condenser. Background Art

[0002] Condenser is a component of refrigeration system, a kind of heat exchanger, which can convert gas or steam into liquid and transfer the heat in the tube to the air near the tube in a very fast way. The working process of condenser is an exothermic process, so the temperature of condenser is relatively high. In the distillation process, the device that converts steam into liquid is also called condenser. All condensers operate by taking away the heat of gas or steam; 2-chloropropionyl chloride reflux condenser is a device for reflux condensation of 2-chloropropionyl chloride, which facilitates collection and recycling by cooling gaseous substances into liquid substances.

[0003] Patent No. CN202121744633.5 discloses a 2-chloropropionyl chloride reflux condenser, which is provided with an outer tube, an inner tube, a condenser, an air inlet pipe, an air outlet pipe, an annular plate, a bracket and a fan blade. The gas enters the condenser in the outer tube through the air inlet pipe, and the coolant enters the outer tube through the water inlet interface. It is divided into two parts on the fixed plate, one part directly flows down to condense the gas in the condenser from the outside, and the other part enters the inner tube to condense the gas in the condenser from the inside. When the gas enters from the air inlet pipe and is output from the air outlet pipe, the gas will drive the bracket in the annular plate to rotate, thereby driving the fan blade to rotate to slow down and guide the gas, so that the gas can contact the condenser more evenly to be condensed, avoiding the phenomenon that the gas may be introduced too fast and cause uneven condensation. The condensation effect is good and the speed is fast, which improves the utilization efficiency of the condenser; by providing a filter plate and a pull ring, the condensate is filtered to prevent blockage, and the filter plate is convenient to clean and replace, thereby improving the convenience of the structure.

[0004] The 2-chloropropionyl chloride reflux condenser disclosed in the above patent is not equipped with a leak detection and early warning cut-off component. 2-chloropropionyl chloride is corrosive, flammable, has a pungent odor, and has a tear-inducing effect. It can severely burn the eyes and skin. If ingested, it can burn the stomach and intestines. If inhaled, it can chemically burn the respiratory tract, which may cause laryngeal and bronchial spasm, inflammation, edema, chemical pneumonia, and pulmonary edema, which is fatal. In order to achieve a better condensation effect, the condenser is usually made of a metal material with good heat transfer effect. It is easily corroded after a long time of use, resulting in leakage of 2-chloropropionyl chloride, which is very dangerous. Utility Model Content

A gas sensor for detecting 2-chloropropionyl chloride gas is arranged in the tank of the 2-chloropropionyl chloride reflux condenser disclosed by the utility model. The gas sensor cooperates with an audible and visual alarm component and a valve cut-off component to give an alarm in time when a gas leaks and cut off a gas escape propagation channel, which is safer and solves the problems raised in the above-mentioned background technology.

Examples of the embodiments are shown in the accompanying drawings, in which the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0021] See also Figures 1 to 4In an embodiment of the utility model, a 2-chloropropionyl chloride reflux condenser comprises a shell 1, a spiral condenser 13 is installed in the shell 1, the shell 1 is a sealed metal tank body, an air inlet 5 and an air outlet 6 are installed at the upper and lower ends of the spiral condenser 13, a first valve 4 is installed at the end of the air inlet 5, a gas sensor 15 is installed on the top of the inner wall of the shell 1, a flash lamp 2 and a buzzer 3 are installed on the top of the shell 1, and a gas sensor 15 for detecting 2-chloropropionyl chloride gas is arranged in the tank of the 2-chloropropionyl chloride reflux condenser disclosed by the utility model, which cooperates with the sound and light alarm component and the valve cut-off component to timely alarm when leaking and cut off the gas escape propagation channel, which is safer.

[0022] A liquid leakage port 11 is provided in the middle of the bottom of the outer shell 1 and is connected to the coolant tank 7 through the liquid leakage port 11. A second valve 12 is installed on the inner wall of the liquid leakage port 11 to facilitate the collection of condensate in the lower part of the outer shell 1 for recycling and saving resources; a sealing cover 8 is detachably installed on the upper liquid inlet of the coolant tank 7 to facilitate the addition of condensate; the spiral condenser 13 is made of a metal material with good thermal conductivity, which is convenient for heat transfer to achieve rapid condensation; a nozzle 14 is installed on the top of the inner wall of the outer shell 1, and the liquid inlet of the nozzle 14 is connected to the liquid outlet of the coolant tank 7 through a pipeline 9 and a suction pump 10, which is convenient for spraying condensate to the outside of the spiral condenser 13 for cooling.

[0023] The working principle of the utility model is as follows: a gas sensor 15 for detecting 2-chloropropionyl chloride gas is arranged in the tank of the 2-chloropropionyl chloride reflux condenser disclosed by the utility model, and in combination with an audible and visual alarm component and a valve cut-off component, an alarm can be given in time when a gas leaks and a gas escape propagation channel can be cut off, which is relatively safe. When the spiral condenser tube 13 is corroded and causes 2-chloropropionyl chloride to leak, the outer shell 1 has a good sealing effect and does not leak, and the gas will not escape into the air. The gas sensor 15 first detects and transmits it to the external control panel, and the control panel controls the flashlight 2 and the buzzer 3 to turn on, giving an audible and visual alarm and attracting staff to come and handle it in time. When the control panel controls the first valve 4, the second valve 12 and the suction pump 10 to be closed at the same time, the first valve 4 closes and seals the inlet of 2-chloropropionyl chloride, and the second valve 12 closes and seals the outlet of the coolant mixed with 2-chloropropionyl chloride in the shell 1, so as to prevent the coolant mixed with 2-chloropropionyl chloride from entering the coolant tank 7 and contaminating the coolant, thereby reducing the loss. At this time, the gas leakage source and the leaked 2-chloropropionyl chloride are both trapped in the shell 1 with good sealing effect, which is very safe and difficult to escape into the air (the flash lamp 2, the buzzer 3, the first valve 4, the second valve 12, the suction pump 10 and the gas sensor 15 are all existing products on the market).

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
