Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like figure 1 Shown is a new type of centralized sewage discharge device, which includes a downcomer 2, a sewage header 5, a sewage pipe joint 4, a lower header 3 and a boiler tube box 1. The boiler tube box 1 has a heating surface tube bundle 8 inside; the lower header 3 is located at the lower part of one side of the boiler tu...

Abstract

The invention discloses a novel centralized blowdown device. The novel centralized blowdown device comprises a downcomer, a blowdown collecting box, a blowdown pipe joint, a lower collecting box and a boiler pipe box, wherein a heating surface pipe bundle is arranged in the boiler pipe box; the lower collecting box is positioned at the lower part of one side of the boiler pipe box in the length direction and is connected with the heating surface pipe bundle; the lower part of the downcomer is connected with the blowdown collecting box which is connected with the lower collecting box; and the blowdown pipe joint is arranged at the lower part of the blowdown collecting box. According to the novel centralized blowdown device, centralized blowdown is achieved through the blowdown collecting box, the thermal stress of the blowdown pipe joint is thoroughly eliminated, and therefore the problem that the blowdown pipe joint cracks due to thermal stress expansion is thoroughly eradicated.

Description

technical field [0001] The invention belongs to the technical field of boiler sewage discharge, and in particular relates to a novel centralized sewage discharge device. Background technique [0002] In order to keep various indicators of boiler water quality within the standard range, it is necessary to continuously remove boiler water with high salt content and deposited sludge from the boiler. Boiler blowdown is an important part of water treatment work and is to ensure that boiler It is an important means for water quality concentration to meet the standard requirements. [0003] At present, the conventional horizontally arranged tube box type waste heat boiler consists of multiple tube boxes connected, each tube box has multiple headers, and multiple sewage outlets need to be set. Directly lead out the sewage pipeline from the header on the pipe box, and the sewage pipe joint on the header will be subjected to expansion thermal stress and cracks will appear at the weld...
