Description

Oil smoke purification device for constant temperature bath and constant temperature bath

Technical Field

The utility model relates to a temperature metrological verification technical field of constant temperature cistern, in particular to oil smoke purifier and constant temperature cell for constant temperature cell.

Background

The constant temperature bath is widely applied to the fields of temperature measurement and verification and environmental experiment measurement because of being capable of providing a stable and uniform temperature field. Different media are filled in the thermostatic bath as liquid baths according to different temperatures required. When it is desired to provide a working temperature of greater than 100 ℃, it is generally possible to select silicone oils or other oils with a boiling point of greater than 100 ℃ as the medium of the liquid bath to be contained in a thermostatic bath. When the oil medium is contained in the thermostatic bath, the oil medium generates oil smoke when the temperature is higher than 150 ℃, and the oil smoke amount is increased along with the rise of the temperature. Oil smoke has many hazards: firstly, laboratories carrying out temperature measurement verification generally require clean experimental conditions, oil smoke pollutes the experimental environment, and oil stains can widely cover the surfaces of laboratory instruments and equipment and are difficult to remove; secondly, the oil smoke seriously affects the measurement accuracy of experimental equipment and destroys experimental conditions; thirdly, the oil smoke harms the physical health of experimenters, and the degree of harm increases along with the rise of the concentration of the oil smoke.

Aiming at the problem of oil smoke in a thermostatic bath, at present, an additional smoke exhaust device is mainly adopted as a response mode, and the response modes of three main flows are as follows: the first method is that the fume hood is adopted to exhaust air, the constant temperature groove is placed in the fume hood, and when the constant temperature groove is used, the exhaust equipment of the fume hood is opened to exhaust oil fume, so that extra investment is needed, the occupied space is large, and an operation area is arranged above a groove opening, so that the oil fume can cause discomfort of an operator, and the metrological verification operation of the temperature is influenced; the second is a range hood method, wherein a range hood is installed above a thermostatic bath, and the range hood is usually required to keep a large installation distance with the thermostatic bath along with the synchronous starting of the thermostatic bath, so that the oil smoke removal capacity of the range hood is limited, and the range hood is usually a main working operation area above the thermostatic bath, and the range hood is installed at the position, which can influence the normal working operation; the third is a matching method of a ventilation pipe and an axial flow fan, the ventilation pipe and the axial flow fan which can move are arranged near the thermostatic bath for smoke discharge, the occupied space is large, and faults are caused by the fact that foreign matters are easy to suck due to the fact that the diameter of an air inlet of the ventilation pipe is large and the air speed is high; high wind speeds can also severely disturb the air in the temperature verification area, interfere with the verification of the temperature and have adverse effects on the temperature verification of the thermostatic bath.

The above three countermeasures have the following three common problems in addition to the problems of each of them: firstly, in order to ensure the complete discharge of oil smoke, the three coping modes all need larger ventilation volume, so that larger working noise can be generated, serious noise pollution is caused, and adverse effects on experimental environment and verification can be generated from multiple aspects such as air flow disturbance, noise interference, oil smoke particle interference and the like; secondly, the oil smoke is discharged to the outside, so that secondary physical transformation is required to be carried out on the experimental space, if a ventilation duct is added, the sealing performance of the experimental space can be reduced by the physical transformation, the heat preservation and temperature equalization performance of experimental equipment can be influenced by the additionally arranged pipeline and the like, and the oil smoke can also store dirt and bring adverse effects to the experimental environment; thirdly, the oil smoke is directly discharged outdoors, which causes air pollution to the external environment.

The smoke suction inlet 21 in this embodiment is semicircular, the exhaust outlet 62 is also semicircular, the two semicircular rings are oppositely arranged to form a circular ring, and the circular ring is positioned right above the notch 11; namely, the air outlet end of the exhaust module 6 is arranged opposite to the smoke suction inlet 21 of the suction module 2.

Because the air current after the primary purification still contains the oil smoke, after the gas vent 62 of this embodiment discharges, some can get into the oil smoke purification device again by flue gas suction inlet 21, carry out secondary oil smoke circulation and purify, so reciprocal, carry out many rounds of circulation and purify, be favorable to reducing the total discharge amount of oil smoke, and promoted the comprehensive purification effect of oil smoke. In addition, when the thermostatic bath carries out thermometer measurement and detection, a plurality of temperature sensors are inserted into the notch 11, the temperature sensing ends of the sensors are immersed under the liquid level of a medium contained in the thermostatic bath body 1, and the wiring ends of the sensors are arranged above the liquid level. When the temperature measurement is carried out in a high-temperature state, the temperature sensing end is in a high-temperature state, the wiring end is in a normal-temperature state, the temperature sensing end can continuously transmit heat to the wiring end due to longitudinal heat conduction of the sensor, the heat transmission process can cause errors to the temperature measurement of the temperature sensing end, and the larger the heat conduction quantity is, the larger the errors are. After setting up heating device in exhaust duct 61 in this embodiment, the air current can be heated by heating device when exhaust duct 61, when exhausting through gas vent 62 again, can be used to heat the wiring end that is located 11 upper spaces of notch for the temperature of sensor wiring end is more close to the temperature sensing end, with the heat transfer volume of reducing the temperature sensing end to the wiring end, has greatly reduced because of the temperature measurement error that the heat transfer caused, has promoted the degree of accuracy of temperature measurement.

The heater in the exhaust duct 61 may be a resistance heating sheet, which is not disposed inside the exhaust duct 61 but attached to the outer surface of the exhaust duct 61; it may be an electric resistance heating wire wound on the outer surface of the exhaust duct 61.

In addition, the PM2.5 value detected by the particulate matter sensor arranged at the exhaust module 6 is A, the PM2.5 value detected by the particulate matter sensor in the air suction module 2 is B, A and B are compared, and when the numerical value of (B-A)/B (namely the reduction amplitude of PM 2.5) is lower than 75%, the controller sends a signal to prompt that the cleaning module 3 of the oil smoke purifying device for the thermostatic bath needs to be cleaned and maintained.
