Embodiment Construction

[0012] The present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, the present invention is a tube-and-tube heat exchanger, which mainly consists of a cylinder body 1, a tube box 2, a nut 3, a tube plate 4, a gasket 5, a drain port 6, a support 7, an exhaust port 8, The heat exchanger 9, the pipe 10, the cleaning port 11, the shell side connecting pipe 12, the equipment flange 13, the heat insulation layer 14, and the baffle plate 15 are composed. The front end of the cylinder 1 is fixedly connected with the tube box 2, and the Two tube sheets 4 are arranged inside the front end and the rear end of the cylinder body 1. The tube sheets 4 are screwed to the cylinder body 1 through nuts 3. The tube sheets 4 are fixedly connected to both ends of the heat exchanger 9. The lower end of the heat exchanger 9 is provided with a tube 10, the middle of the heat exchanger 9 is provi...

Abstract

The invention discloses a tube-and-tube heat exchanger, which mainly consists of a cylinder body, a tube box, a nut, a tube plate, a gasket, a liquid discharge port, a support, an exhaust port, a heat exchanger, a pipe, a cleaning port, a shell The front end of the cylinder body is fixedly connected with the pipe box. There are two tube plates inside the front end and the rear end of the cylinder body. The tube plate is screwed to the cylinder body through nuts. The plate is fixedly connected to both ends of the heat exchanger, the lower end of the heat exchanger is provided with a tube, the middle of the heat exchanger is provided with a baffle plate, the bottom of the front end of the cylinder is provided with a liquid discharge port, and the bottom of the rear end of the cylinder is fixedly connected with the shell side pipe. The lower end of the cylinder is fixedly connected with the support, and there is a cleaning port in the middle of the support. The cleaning port is threaded with the lower end of the cylinder, the rear end of the cylinder is threaded with the equipment flange, and the inner wall of the cylinder is fixedly connected with the heat insulation layer. The invention has the beneficial effects of convenient cleaning, prolonged service life and no water leakage problem.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a tube-and-tube heat exchanger. Background technique [0002] The shell and tube heat exchanger is the most widely used heat exchanger in chemical and alcohol production. It is mainly composed of shell, tube sheet, heat exchange tube, head, baffle and so on. During heat exchange, one kind of fluid enters from the connecting pipe of the head, flows in the pipe, and flows out from the outlet pipe at the other end of the head, which is called the tube side; The other pipe on the shell flows out, which is called a shell-side shell-and-tube heat exchanger. If the inlet and outlet temperature of the hot fluid for the purpose of cooling in the heat exchanger has been determined by the process conditions, the outlet temperature of the cooling medium needs to be selected. If you choose a higher outlet temperature, you can choose a small heat exchanger, but the flow rate of the coolin...
