Description

A kind of feeding device adding sulphuric acid in lab scale reactor

Technical field

This utility model relates to a kind of feeding device, particularly relates to add the feeding device of sulphuric acid in lab scale reactor.

Background technology

In the lab scale reactor of experiment, sulphuric acid reacts conventional raw material or catalyst uses as a kind of, due to Being lab scale reactor, use the pipe method of industrialization form to add sulphuric acid uneconomical, the interpolation of sulphuric acid is often by simply Funnel or alternate manner pour into from the charge door of reactor, such adding procedure has certain danger, and one is sulphuric acid Adding procedure there is the danger of leakage, two is that pressure ratio is higher in lab scale reactor still, during adding sulphuric acid, from instead Answer harmful gas that still produces easily in still charge door come up, especially add cold sulphuric acid, this harmful gas of emerging becomes Must be more prone to.

Summary of the invention

For the deficiencies in the prior art, this utility model provides a kind of charging dress adding sulphuric acid in lab scale reactor Put.

This utility model is realized by below scheme: a kind of feeding device adding sulphuric acid in lab scale reactor, bag Include loading hopper, it is characterised in that: the lower section of upper loading hopper arranges a mozzle, described mozzle, and its two ends are respectively provided with Upper horn mouth and lower horn mouth, upper horn mouth is positioned at the top of mozzle, lower horn mouth is positioned at the lower section of mozzle, and is leading Under flow tube, bell-mouthed outside has been also connected with flange coupling connector.

Further, described mozzle, there is inside it one layer of glass-lined for anti-sulfuric acid corrosion.

Further, described upper loading hopper, the diameter of its underpart drainage tube is less than the diameter of mozzle, and its underpart Drainage tube penetrates with in horn mouth so that have space between bottom drainage tube and the mozzle of upper loading hopper.

This utility model, has lower horn mouth on feeding device, and thus, in reactor, harmful gas is through lower horn mouth Time condensate can be back in still by lower horn mouth.

This utility model, feeding device has on horn mouth, upper horn mouth and upper loading hopper obtain between drainage tube have Having space, thus, a small amount of harmful gas in reactor obtains the space between drainage tube through upper horn mouth and upper loading hopper, At upper horn mouth, diffusion is emerged, and is possible to prevent harmful gas directly to rush to the face of operator in still, reduces harmful gas The harm of body, between space so that sulphuric acid is more stable during being flowed into reactor, will not be by gas in still The impact of body pressure.

This utility model, the flange coupling connector of feeding device can carry out compact siro spinning technology with the charge door of reactor, adds During sulphuric acid, adding from upper loading hopper, sulphuric acid enters reactor, lower horn mouth and mozzle by upper loading hopper and mozzle The liquid splash that setting is possible to prevent in reactor goes out outside still.

A kind of feeding device adding sulphuric acid in lab scale reactor that this utility model provides, it is to avoid interpolation sulphuric acid mistake The problem that in journey, in still, harmful gas is emerged, liquid splash goes out outside still in still, is greatly improved in lab scale reactor interpolation sulfur The safety of acid.

Accompanying drawing explanation

Fig. 1 is that this utility model implements schematic diagram.

Fig. 2 is feeding device schematic diagram.

Wherein: under 1-reactor, 2-feeding device, the upper loading hopper of 201-, 202-mozzle, the upper horn mouth of 203-, 204- Horn mouth, 205-flange coupling connector, 206-glass-lined.

Detailed description of the invention

Below in conjunction with the accompanying drawings embodiment of the present utility model is made brief description.

In Fig. 2, a kind of feeding device adding sulphuric acid in lab scale reactor, including upper loading hopper 201, its feature exists In: the lower section of upper loading hopper 201 arranges a mozzle 202, described mozzle 202, and its two ends are respectively provided with horn mouth 203 and lower horn mouth 204, upper horn mouth 203 is positioned at the top of mozzle 202, and lower horn mouth 204 is positioned at mozzle 202 times Side, and it has been also connected with flange coupling connector 205 in the outside of the lower horn mouth 204 of mozzle 202, have inside mozzle 202 One layer of glass-lined 206 for anti-sulfuric acid corrosion.

In Fig. 1, feeding device 2 is connected on the charge door of reactor 1, and lower horn mouth 204 below is positioned at reactor 1 Inside, in reactor 1, harmful gas condensate when lower horn mouth 204 can be back in still by lower horn mouth 204；With Time a small amount of harmful gas from reactor 1 through upper horn mouth 203 and upper loading hopper 201 space between drainage tube, Spread at upper horn mouth 203 and emerge, be possible to prevent harmful gas directly to rush to the face of operator in still, reduce harmful The harm of gas, between space so that sulphuric acid is more stable during being flowed into reactor 1, will not be by still The impact of gas pressure, the flange coupling connector 205 of feeding device 2 can carry out compact siro spinning technology with the charge door of reactor 1, adds During sulphuric acid, adding from upper loading hopper 201, sulphuric acid enters reactor 1, lower horn mouth by upper loading hopper 201 and mozzle 202 204 and the liquid splash that is possible to prevent in reactor 1 of the setting of mozzle 202 go out outside still.
