Abstract
The utility model relates to a polyester process column top micro-positive pressure steam heat recovery device, which comprises a reactor kettle (1), a process column (2) and a sewage treatment device (5), wherein the reactor kettle (1), the process column (2) and the sewage treatment device (5) are serially connected sequentially. The steam heat recovery device is characterized in that a heat exchanger (2) is arranged on a connecting pipeline between the process column (2) and the sewage treatment device (5) and connected with a refrigerator (4). The polyester process column top micro-positive pressure steam heat recovery device recovers polyester process column top micro-positive pressure steam heat through the heat exchanger and the refrigerator (4), reduces temperature of industrial waste water and is favorable for sewage treatment.
Description
(1) technical field
The utility model relates to a kind of polyester process column overhead pressure-fired steam heat retrieving arrangement.
(2) background technology
Before the utility model is made, in the polyester production process, mixed gas after the reaction kettle for reaction enters process tower, after separating in process tower, the liquid at the bottom of the tower enters the glycol recovery storage tank, and the pressure-fired steam that contains organic impurity of cat head is about 103 ℃, directly be delivered to waste disposal plant by pipeline, cause the temperature of trade effluent higher, be unfavorable for the processing of sewage, and cause the waste of heat energy.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and utilizes latent heat, reduces the trade effluent temperature, helps the polyester process column overhead pressure-fired steam heat retrieving arrangement of sewage disposal.
The purpose of this utility model is achieved in that a kind of polyester process column overhead pressure-fired steam heat retrieving arrangement, comprise the reactor, process tower and the waste disposal plant that are connected in series successively, the connecting pipeline that it is characterized in that described process tower and waste disposal plant is provided with interchanger, and described interchanger is connected with refrigerator.
A kind of polyester process column overhead of the utility model pressure-fired steam heat retrieving arrangement reclaims polyester process column overhead pressure-fired steam thermal energy by interchanger and refrigerator, has reduced the trade effluent temperature, helps sewage disposal.
(4) description of drawings
The structural representation of a kind of polyester process column overhead pressure-fired steam heat retrieving arrangement that Fig. 1 relates to for the utility model.
Among the figure:
(5) embodiment
Referring to Fig. 1, a kind of polyester process column overhead pressure-fired steam heat retrieving arrangement that the utility model relates to, mainly by reactor 1, process tower 2, interchanger 3, refrigerator 4, waste disposal plant 5 and glycol recovery storage tank 6 are formed, described reactor 1 is connected in series with process tower 2, described process tower 2 bottom liquid exits are connected with glycol recovery storage tank 6, the outlet of described process tower 2 tops is connected with waste disposal plant 5 by pipeline, described process tower 2 is provided with interchanger 3 with the connecting pipeline of waste disposal plant 5, and described interchanger 3 is connected with refrigerator 4.
