Abstract
The utility model discloses an optimized reflux system applied to an ethylene glycol heat exchanger. The system comprises at least one heat exchanger, a control device and a storage tank; the heat exchanger is connected with the control device through a reflux pipeline; the control device is connected with the storage tank through a reflux pipeline; an input port and an output port of the heat exchanger are respectively arranged on two sides of the heat exchanger; a valve is arranged at the input port end; and the control device is provided with two parallel reflux passages. The optimized reflux system is simple in structure, reasonable in design and layout and high in practicability, and avoids equipment faults due to blockage; due to the two parallel reflux passages, the production efficiency and the production continuity are improved, and production shutdown caused by blockage of the automatic controlled reflux passages in the flux process can be prevented; automatic control valves are arranged in the automatic controlled reflux passages and do not require manual operation, so that start and stop of equipment can be automatically controlled according to production requirements, the labor intensity of production of operation persons is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of return-flow system, is specifically related to a kind of optimization return-flow system that is applied to the ethylene glycol heat exchanger.
Background technology
In the polyester production process, use ethylene glycol as raw materials for production through regular meeting, high-purity ethylene glycol temperature is higher; Need pass through heat exchanger reduction temperature in use just can output in the production; Be provided with return-flow system between from the storage tank to the heat exchanger, the input/output port of original return-flow system is in heat exchanger the same side, and the reflux line caliber is too little, elbow is too much and layout is unreasonable; Easy blocking; Cause the liquid level adjusting of heat exchanger often to break down, in case mediation and the maintenance of equipment of just must stopping production that break down influences the normal operation and the continuation production of producing.
The utility model content
The utility model technical problem to be solved is to provide a kind of optimization return-flow system that is applied to the ethylene glycol heat exchanger, and the equipment fault of avoiding the blockage problem because of return-flow system to cause is enhanced productivity and continuation.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of optimization return-flow system that is applied to the ethylene glycol heat exchanger; Comprise at least one heat exchanger, control device and storage tank; Connect through reflux line between said heat exchanger and the control device, be connected through reflux line between said control device and the said storage tank, the input port of said heat exchanger and delivery outlet are located at said heat exchanger both sides respectively; Said input port end is provided with valve, and said control device is provided with two return flow lines arranged side by side.
Preferably further technological improvement; In the utility model, said two return flow lines arranged side by side are respectively automatic control return flow line and semiautomatic control return flow line, are provided with two return flow lines arranged side by side and help the continuation of enhancing productivity and producing; The production that can prevent to cause when controlling the return flow line automatically stopping state occurs in reflux course is stopped work; Said automatic control return flow line is provided with autocontrol valve, and autocontrol valve does not need manually-operated, can according to production requirement voluntarily control appliance startup and stop; Reduced production operation personnel's labour intensity; Improved production efficiency, said semiautomatic control return flow line is provided with two manually-operated gates and an electrically operated valve, and said manually-operated gate is located at said electrically operated valve both sides respectively.
Preferably further technological improvement, in the utility model, the number of said heat exchanger is 2.
The utility model contrast prior art has following advantage: simple in structure, layout is reasonable, and is practical; The equipment fault of avoiding the blockage problem because of return-flow system to cause; Be provided with two return flow lines arranged side by side and help the continuation of enhancing productivity and producing, can prevent that the production that causes when controlling the return flow line automatically stopping state occurs in reflux course from stopping work, control the return flow line automatically and be provided with autocontrol valve; Autocontrol valve does not need manually-operated; Can according to production requirement voluntarily control appliance startup and stop, having reduced production operation personnel's labour intensity, improved production efficiency.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Existing with reference to accompanying drawing, further explain the utility model.
As shown in Figure 1; A kind of optimization return-flow system that is applied to the ethylene glycol heat exchanger comprises at least one heat exchanger 1, control device 2 and storage tank 3, connects through reflux line 4 between heat exchanger 1 and the control device 2; Be connected through reflux line 4 between control device 2 and the storage tank 3; The input port 11 and the delivery outlet 12 of heat exchanger 1 are located at heat exchanger 1 both sides respectively, and input port 11 ends are provided with valve 110, and control device 2 is provided with two return flow lines arranged side by side.
For better production; In the present embodiment, two return flow lines arranged side by side are respectively automatic control return flow line 21 and semiautomatic control return flow line 22, are provided with two and return flow line and help the continuation of enhancing productivity and producing; The production that can prevent to cause when controlling return flow line 21 automatically stopping state occurs in reflux course is stopped work; Automatically control return flow line 21 is provided with autocontrol valve 211, and autocontrol valve 211 does not need manually-operated, can according to production requirement voluntarily control appliance startup and stop; Reduced production operation personnel's labour intensity; Improved production efficiency, semiautomatic control return flow line 22 is provided with two manually-operated gates 221 and an electrically operated valve 222, and manually-operated gate 221 is located at electrically operated valve 222 both sides respectively.
In order better to produce, the number of heat exchanger 1 can be provided with according to producing voluntarily, and in the present embodiment, the number of heat exchanger 1 is 2.
Aborning generally, high-purity ethylene glycol leads in the heat exchanger 1 through reflux line 4 in the holding vessel, and it is open to control return flow line 21 automatically, and semiautomatic control return flow line 22 is closed; When being in an emergency, control return flow line 21 automatically and stop up, to control return flow line 21 automatically and close, semiautomatic control return flow line 22 is open, produces to continue to carry out.
Above-described the utility model embodiment does not constitute the qualification to the utility model protection domain.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the claim protection domain of the utility model.
