Description

With the reactor of low pressure drain

Technical field

The utility model belongs to technical field of waste gas treatment, particularly relates to a kind of reactor with low pressure drain.

Background technology

In ink manufactures, easy volatile solvent often can be used in reactor inside, if these solvent gas directly discharge, while causing atmosphere pollution, the solid of ink also can be made to change, and then affect product quality.

Usual solution is: 1, install condenser, get back to reactor after making the solvent gas condensation of volatilization, its shortcoming needs cooling water, and construction is complicated, and investment is large.2, mounting safety valve, discharges when exceeding rated pressure, and its shortcoming is that spool easily blocks, after paraffin, carbon black are by safety valve cooled and solidified, cause safety valve malfunctioning, and inconvenience maintenance, can only ensure as the later stage of safety.

This just needs to increase low pressure drain before reactor internal pressure does not reach rated pressure, reduces or exempts normal pressure and discharge the series of problems brought.

Utility model content

The utility model, in order to solve weak point of the prior art, provides a kind of reactor with low pressure drain, achieves the low pressure drain of volatilization gas in reactor, and structure simple, easy to operate, safe and reliable, be beneficial to environmental protection.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: the reactor of band low pressure drain, it comprises reactor body and low pressure drain, the top of reactor body is provided with downtake pipe, downtake pipe and reactor inner space, the shaft of band blade is provided with in reactor body, shaft and external motor are in transmission connection, reductor is provided with between described shaft and motor, the second exhaust pipe that described low pressure drain comprises lift check valve and arranges in the horizontal direction, described second exhaust pipe is communicated with described downtake pipe, described lift check valve is arranged on described second exhaust pipe.

Described reactor body is provided with the Pressure gauge for detection reaction still inner chamber.

Described downtake pipe is vertically arranged.

The beneficial effects of the utility model:

Adopt technique scheme, the second exhaust pipe that low pressure drain comprises lift check valve and arranges in the horizontal direction, described second exhaust pipe is communicated with described downtake pipe, described lift check valve is arranged on described second exhaust pipe, during work, the volatilization gas of reactor inner chamber is accumulated at reactor inner chamber and produces certain pressure, when its insufficient pressure is to back down the spool of lift check valve, lift check valve is in closure state, volatilization gas can not be discharged, until when the spool of lift check valve backs down by the gas pressure of reactor inner chamber accumulation, lift check valve is in open mode, volatilization gas is discharged, after gas discharges a part, the gas pressure of reactor inner chamber reduces, the spool of lift check valve resets under gravity, lift check valve closes, continuous repetition said process completes the low pressure drain of volatilization gas in reactor, reduce reactor internal solvent gaseous volatilization, its structure is simple, easy to operate, be beneficial to environmental protection.After installing low pressure drain, reactor internal solvent gas no longer carries out normal pressure discharge, maintains the relatively stable of solid content, also just ensure that the relatively stable of quality.

The upper cover of lift check valve can open cleaning spool and valve pocket, keeps the clean of lift-type check valve core and valve pocket, avoids spool jams, safe and reliable; Reactor body is provided with the Pressure gauge for detection reaction still inner chamber, for observing the force value of reactor inner chamber; Downtake pipe is vertically arranged, and the volatilization gas of reactor inner chamber easierly can enter downtake pipe, the second exhaust pipe thus gas better leads by gas.Be provided with the shaft of band blade in reactor body, shaft and external motor are in transmission connection, and are provided with reductor between described shaft and motor, and the stability arranging the rotation of guarantee shaft of motor and reducing motor, reduces the volatilization of solvent gas.

Accompanying drawing explanation

Fig. 2 is the structural representation of lift check valve in the utility model.

Detailed description of the invention

As depicted in figs. 1 and 2, the reactor of band low pressure drain of the present utility model, it comprises reactor body 3 and low pressure drain, the top of reactor body 3 is provided with downtake pipe 1 vertically, downtake pipe 1 is communicated with reactor inner chamber 10, reactor body 3 is provided with the Pressure gauge 4 for detection reaction still inner chamber 10, the shaft 6 of band blade is provided with in reactor body 3, shaft 6 and external motor 8 are in transmission connection, and are provided with reductor 7 between described shaft 6 and motor 8.The second exhaust pipe 2 that described low pressure drain comprises lift check valve 5 and arranges in the horizontal direction, described second exhaust pipe 2 is communicated with described downtake pipe 1, and described lift check valve 5 is arranged on described second exhaust pipe 2.

Lift check valve in the utility model, can need according to enterprise self spool making Different Weight, spool weight is selected according to blowdown presssure and drift diameter area, and in the present embodiment, the weight of spool is applicable to the low pressure drain of 0-10Kpa.After production terminates, the upper cover 53 of lift check valve 5 is opened, just can clear up spool 52 and valve pocket 51 very easily, keep its stable performance (lift check valve 5 is prior art, and structure and the annexation of the parts such as its spool 52, valve pocket 51, upper cover 53 no longer describe in detail).

During utility model works, the volatilization gas of reactor inner chamber 10 is accumulated at reactor inner chamber 10 and produces certain pressure, when its insufficient pressure is to back down the spool 52 of lift check valve 5, lift check valve 5 is in closure state, volatilization gas can not be discharged, until when the spool 52 of lift check valve 5 backs down by the gas pressure that reactor inner chamber 10 accumulates, lift check valve 5 is in open mode, volatilization gas is discharged, after gas discharges a part, the gas pressure of reactor inner chamber 10 reduces, the spool 52 of lift check valve 5 resets under gravity, lift check valve 5 closes, continuous repetition said process completes the low pressure drain of volatilization gas in reactor, reduce reactor internal solvent gaseous volatilization, its structure is simple, easy to operate, safe and reliable, be beneficial to environmental protection.After installing low pressure drain, reactor internal solvent gas no longer carries out normal pressure discharge, maintains the relatively stable of solid content, also just ensure that the relatively stable of quality.

In the present embodiment, the design of spool is applicable to the low pressure drain of 0-10Kpa, for the reactor of still internal solvent gas pressure within the scope of 0-10Kpa, substantially can accomplish not discharge, decrease atmosphere pollution in production process after installing low pressure drain additional.

Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify to the utility model or equivalent replacement, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
