Abstract
The utility model discloses a but automatic safe carminative shell and tube type heat exchanger exhaust apparatus, its characterized in that heat exchanger section of thick bamboo wall top or head top are equipped with the gas vent, and the gas vent meets with heat exchanger shell side medium outlet pipeline. When heat exchange equipment normally operates, non-condensable gas at the top of the liquid phase side of the shell-and-tube heat exchanger can be discharged through an exhaust port, namely a gas phase outlet, formed in the top of the tube wall of the heat exchanger or the top of the end enclosure of the shell-and-tube heat exchanger, and then the non-condensable gas is collected into an outlet pipeline at the side of the shell-and-tube heat exchanger through a pipeline after passing through an exhaust valve and then is taken away by a medium in the pipeline.
Description
Technical Field
The invention relates to an automatic exhaust device for non-condensable gas or harmful gas of heat exchange equipment in chemical product production, in particular to an exhaust device of a shell-and-tube heat exchanger.
Background
The shell-and-tube heat exchanger is the most widely applied heat exchanger in the chemical production at present. The heat exchanger mainly comprises a shell, a tube plate, a heat exchange tube, an end enclosure, a baffle plate or a shell and a tube bundle. The material can be common carbon steel, stainless steel and the like. When heat exchange is carried out, a fluid enters from one side of the tube pass, flows in the tube and flows out from the outlet side of the other end, which is called the tube pass; the other fluid enters from a connecting pipe of the shell and flows out from the other connecting pipe on the shell, and the other fluid is called shell side. In the design and use of the shell-and-tube heat exchanger, exhaust ports are arranged at the highest points of a tube pass and a shell pass and are used for leading out gas accumulated at dead angles of equipment in time. The gas exhaust port is convenient for ensuring that the medium is full in a hydraulic test during equipment manufacturing, inspection and maintenance, and the function of the liquid phase gas exhaust port is mainly embodied, so that on one hand, a flowing dead zone cannot be formed in the heat exchanger due to the existence of local gas, and the effective utilization of the heat exchanger is not influenced; on the other hand, the problem of local corrosion aggravation of the heat exchanger caused by the existence of the gas medium is avoided. And then the harmful gas can not be accumulated to cause potential safety hazard. In daily production, the commonly adopted discharge mode is to discharge by manually and periodically operating a valve. By adopting the manual mode, the influence of human factors on the production stability is larger, and the safety of production and heat exchange equipment is possibly influenced because the discharge is not timely; and industrial accidents caused by high temperature, corrosion and other dangerous media in discharge and pollution or damage to the environment can also be caused due to improper operation.
Disclosure of Invention
The invention provides a shell-and-tube heat exchanger exhaust device capable of automatically and safely exhausting gas, and aims to solve the problem of potential safety hazard caused by untimely and incomplete manual discharge of harmful gas accumulation in a dead angle area of a shell-and-tube heat exchanger device.
The exhaust device of the shell-and-tube heat exchanger capable of automatically and safely exhausting gas comprises a tube array or an internal tube bundle arranged on a tube plate, and is characterized in that the top of the wall of the tube or the top of a seal head of the heat exchanger is provided with an exhaust port, and the exhaust port is connected with a medium outlet pipeline on the shell side of the heat exchanger through an exhaust valve.
The invention achieves the technical progress that: when the heat exchange equipment normally operates, because the exhaust valve is normally open, noncondensable gas or harmful gas which influences the heat transfer performance and is accumulated in a dead angle area at the top of the shell-and-tube heat exchanger can be discharged through an exhaust port which is a gas phase outlet and is arranged at the top of the tube wall of the heat exchanger or the top of the end socket of the heat exchanger, then the exhaust valve in a normally open state is converged into an outlet pipeline at the side of the heat exchanger shell through a pipeline and then taken away by a medium in the pipeline, the discharge process of the gas medium at the top of the liquid phase side is safe and reliable, and dead angles which cannot be completely replaced can be essentially. Its advantages are mainly embodied as follows:
①, the workload of manually opening the exhaust valve periodically for exhausting is reduced, and the labor load of staff is reduced;
②, the influence of human factors on the production process caused by untimely and incomplete exhaust is avoided, and the stable operation of the production device and the equipment safety of the shell and tube heat exchanger are ensured;
③ avoid the possibility of manual discharge of media, which can cause industrial accidents to staff and negative environmental impact.
