Tank.
Background technology
, it is necessary to adding liquid catalyst in trichloro-acetic chloride chlorination reaction process.The catalyst is pyridines material, easily
With chlorination process generate hydrogen chloride forming salt and lose catalytic effect, therefore need be added to liquid bottom, it is existing plus catalysis
Agent mode is：Stop the hydrogen chloride gas in logical chlorine, emptying reactor, with the charging hopper for being inserted into reactor bottom intubation
Add.The defect and deficiency of prior art：Need to stop reacting, cause the reaction time to extend；Emptying gas need Alkali absorption, increase
High-salt wastewater amount is added；Charging process has a small amount of gases affect site environment.
The content of the invention
The invention aims to overcome the deficiencies in the prior art and provide it is a kind of it is reasonable in design, easy to operate, to reaction
Process is disturbed less, without addition after pressure release and the few catalyst shot tank for trichloro-acetic chloride chlorination reaction of waste gas discharge.
To reach above-mentioned purpose, present invention employs following technical scheme.
A kind of catalyst shot tank for trichloro-acetic chloride chlorination reaction, including tank body, feed pipe, inlet valve, L-type
Pipe, adpting flange, pressure gauge, air inlet pipe, connection flexible pipe, nitrogen pot, air entraining valve, discharge nozzle, charging tubule and outlet valve, it is described
The upper end of tank body is provided with feed pipe；Inlet valve is installed on the feed pipe；Pass through L-type Guan An on the left side wall of the tank body
Equipped with adpting flange；The pressure gauge is fixed on adpting flange top；Air inlet pipe is provided with the right side wall of the tank body；It is described
Air inlet pipe is connected by connecting flexible pipe with nitrogen pot；Intake valve has been installed in the air inlet pipe；The bottom of the tank body is set
It is equipped with discharge nozzle；The lower end of the discharge nozzle is connected with charging tubule；Outlet valve is also equipped with the discharge nozzle.
It is further improved as the present invention, it is also equipped with deck on the periphery wall of the tank body.
It is further improved as the present invention, it is additionally provided with graduated scale on the outer wall of the tank body.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：The present invention program is led to
Cross and sealable catalyst shot tank body is set, and set feed pipe, bottom that discharge nozzle is set, and has corresponding control on top
Valve processed control opening and closing, caching effect can be played with tank body, charging once can be added repeatedly on demand, it is to avoid each addition is all
Obtain the cumbersome advantageous effects of feed operation；The technical program is also provided with air inlet pipe, connection flexible pipe, nitrogen pot, air entraining valve
And pressure gauge, it can control adding amount of the nitrogen to tank body by observing manometric data, keep the filling institute in tank body
The positive air pressure needed, with Stress control it is stable, fill it is smooth, to former reaction interference less, waste gas discharge few advantageous effects；
The technical program is also provided with elongated charging tubule, with urging that the big pot bottom of filling, raising needed for conveniently stretching into are filled
Agent and the original advantageous effects fully reacted；The technical program is provided with deck also on the outer wall of tank body, with side
Carried when just filling and hypothesis is suitable for reading in the reaction vessel of required filling, reduce the cumbersome Advantageous effect manually held
Really；The technical program is also provided with graduated scale, surplus in catalyst adding amount and convenient observation tank body with can accurately control
The advantageous effects of remaining catalyst storage amount.
