Problems solved by technology

[0002] In the process of sewage treatment, some substances that are easy to solidify, such as grease, need to be heated before they can be processed. The heating tubes of the heaters commonly used in the market for sewage treatment are directly in contact with sewage. During the long-term heating process, grease, scale, etc. are harmful. The substance will adhere to the surface of the heating tube, thus forming a thick layer of dense material covering the surface of the heater, making it difficult for the heat of the heater to dissipate. After a long time, it will cause the tube to burst and accelerate the corrosion and aging of the heating tube. , and also reduces the thermal efficiency

Embodiment 1

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] Such as figure 1 , 2 As shown, a sewage treatment heater includes a heating element. It also includes a small flange, a large flange 4 and a closing sleeve 3. The heating element includes a heating tube 1, such as Figure 3-6 As shown, the heating tube 1 is a U-shaped or 3U-shaped heating tube. The end of the heating tube 1 is welded on the small flange 2 .

[0027] Such as Figure 7 , 8 As shown, the sleeve 3 is arranged on the large flange 4 by argon arc welding, the sleeve 3 must be airtight, and can withstand at least 6bar pressure. The heating element is arranged in the sleeve 3, and the sleeve 3 is filled with a heat transfer medium. The heating pipe 1 passes through the heat transfer medium such as air or heat transfer oil inside the heating sleeve 3, and then transfers the heat to the sleeve 3, and the sleeve 3 effectively...

Abstract

The invention belongs to the field of electric heating tubes, and particularly relates to a sewage treatment heater. The sewage treatment heater comprises a heating element. The sewage treatment heater further comprises a small flange, a large flange and a closed sleeve; the heating element comprises a heating pipe, and the end part of the heating pipe is welded to the small flange; and the end part of the sleeve is welded to the large flange, the heating element is arranged in the sleeve, the small flange is detachably connected with the large flange, a junction box is arranged at the upper part of the small flange, and a gland is arranged on the junction box. According to the sewage treatment heater , the heating pipe is prevented from making direct contact with harmful substances such as grease in sewage, so that the adhesion of scale grease is avoided, the accumulation of temperature on the surface of the pipe is effectively prevented, and the risk of pipe explosion is avoided; and due to the fact that the heating pipe does not make direct contact with the sewage, the service life of the heating pipe is greatly prolonged, and the maintenance cost is saved.

Description

technical field [0001] The invention belongs to the field of electric heating pipes, and in particular relates to a sewage treatment heater. Background technique [0002] In the process of sewage treatment, some substances that are easy to solidify, such as grease, need to be heated before they can be processed. The heating tubes of the heaters commonly used in the market for sewage treatment are directly in contact with sewage. During the long-term heating process, grease, scale, etc. are harmful. The substance will adhere to the surface of the heating tube, thus forming a thick layer of dense material covering the surface of the heater, making it difficult for the heat of the heater to dissipate. After a long time, it will cause the tube to burst and accelerate the corrosion and aging of the heating tube. , and also reduces the thermal efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sewage treatm...
