Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a steam jet heater for sewage heating. Background Art

[0002] Sewage treatment requires heating, mainly based on the needs of chemical reactions and biological activities in the sewage treatment process. First, heating can increase the reaction rate of organic matter in sewage, promote their faster decomposition or conversion, and thus improve the efficiency of sewage treatment. Secondly, for sewage treatment systems that use biological treatment methods, such as the activated sludge method, the activity of microorganisms is directly affected by temperature. Proper heating can ensure that microorganisms are active within the optimal temperature range, thereby more effectively degrading organic matter in sewage. In addition, heating can prevent certain substances in sewage from solidifying or solidifying at low temperatures, avoiding problems such as pipe blockage.

[0003] The existing sewage pool uses steam coils and air stirring to heat sewage. When the steam enters the sewage pool, water hammer is easily formed due to the large temperature difference between the steam pipeline and the sewage, causing a large impact on the pipeline and equipment and generating noise. The vibration accelerates damage to equipment and pipelines, and the noise can easily cause occupational contraindications.

[0004] Based on this, the utility model proposes a steam jet heater for sewage heating which eliminates vibration and reduces noise. Utility Model Content

[0005] In order to overcome the disadvantages of the existing sewage heating method using steam coils and air stirring, in which steam entering the sewage pool is prone to produce large impact and noise, which not only damages the equipment but also causes discomfort to people, the utility model provides a steam jet heater for sewage heating with vibration removal and noise reduction.

[0006] A steam jet heater for sewage heating comprises a water tank, a steam pipe, a rotary joint and a steam ejector. The steam pipe is connected to the rotary joint. The rotary joint is provided with three spiral branches. The three branches are respectively connected to the steam ejector through flanges. The steam ejector consists of a delivery pipe, a nozzle and a diffusion chamber. The delivery pipe is connected to the branch pipe of the rotary joint. The end of the delivery pipe is provided with a nozzle. The diffusion chamber is connected to the outside of the nozzle.

[0007] As a further preferred solution, the pressure diffusion chamber is provided with a water inlet and a water outlet to form water pressure, thereby driving the rotary joint to rotate.

[0008] As a further preferred solution, a bearing is provided between the steam pipe and the rotary joint.

[0009] As a further preferred solution, a sealing ring is also included, and the sealing ring is arranged at the connection between the rotary joint and the water pool.

[0010] As a further preferred solution, a hollow portion is provided at the bottom end of the steam pipe, and the hollow portion is a sealing groove, and the rotary joint is rotatably connected in the sealing groove.

[0011] As a further preferred solution, it also includes a top cover, which is embedded in the top of the pool.

[0012] As a further preferred solution, an observation window is also included, and the top cover is provided with an observation window.

[0013] As a further preferred solution, a stabilizing bracket is also included, which is fixed to the water tank and supports and fixes the steam pipe.

[0014] As a further preferred solution, a protective pad is also included, and the protective pad is sleeved on the outside of the steam pipe.

[0015] The utility model has the following advantages: 1. The steam ejector is placed in the sewage, which not only reduces the vibration of the traditional steam pipeline to the sewage, but also effectively reduces the noise. At the same time, the rotation of the rotary joint drives the sewage in the pool to stir, thereby improving the heat transfer efficiency.

[0016] 2. Steam is directly introduced into water, without condensed water to carry away heat loss, which is highly efficient and energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0023] Embodiment: A steam jet heater for sewage heating, such as Figure 1-4 As shown, it includes a water pool 1 and a steam pipe 2, a top cover 12 is embedded in the top of the water pool 1, the top cover 12 is provided with an observation window 13, a protective pad 15 is sleeved on the outside of the steam pipe 2, when the steam is transmitted, the protective pad 15 can insulate the steam pipe 2 to prevent heat leakage, and also includes a rotary joint 201 and a steam injector, the steam pipe 2 is connected with the rotary joint 201, a bearing 9 is arranged between the steam pipe 2 and the rotary joint 201, the device adopts a deep groove ball bearing 9, which effectively reduces the friction coefficient between the steam pipe 2 and the rotary joint 201, the rotary joint 201 is provided with three spiral branches, the three branches are respectively connected to the steam injector through the flange 3, the steam injector is composed of a delivery pipe 4, a nozzle 5 and a diffusion chamber 6, the delivery pipe 4 is connected to the branch pipe of the rotary joint 201, the end of the delivery pipe 4 is provided with a nozzle 5, and the diffusion chamber 6 is connected to the outside of the nozzle 5.

[0024] like Figure 2 and Figure 3 As shown, the diffusion chamber 6 is provided with a water inlet 7 and a drain outlet 8. Sewage continuously enters from the water inlet 7 and is discharged from the drain outlet 8, forming a water flow which in turn drives the rotary joint 201 to rotate, thereby driving the sewage to be stirred.

[0025] like Figure 2 As shown, a sealing ring 10 is also included, and the sealing ring 10 is arranged at the connection between the rotary joint 201 and the pool 1.

[0026] like Figure 2 As shown, the bottom end of the steam pipe 2 is hollow, and the hollow part is a sealing groove 11. The rotary joint 201 is rotatably connected in the sealing groove 11. The bottom end of the steam pipe 2 wraps the upper end of the rotary joint 201 from top to bottom to prevent steam condensation from escaping.

[0027] like Figure 2 As shown, a stabilizing bracket 14 is also included. The stabilizing bracket 14 is fixedly connected to the water pool 1. The stabilizing bracket 14 supports and fixes the steam pipe 2. When the steam is transmitted, the stabilizing bracket 14 can effectively support and fix the steam pipe 2, thereby ensuring the stability of the steam pipe 2.

[0028] Working principle: sewage is introduced into the water pool 1, and the steam pipe 2 is connected to a steam peripheral device. Steam will be continuously introduced into the steam pipe 2. Since the steam ejector is located in the sewage, the steam is discharged from the nozzle (the nozzle is equipped with a front valve to control the steam discharge amount) and then fully contacts with the sewage through the expansion chamber 6, and the sewage is efficiently heated by heat transfer. At the same time, sewage continuously enters from the water inlet 7 and is discharged from the outlet 8 to form a water flow. The rotary joint 201 will continue to rotate to form a submerged stirring effect, which not only improves the heat transfer efficiency in the sewage, but also effectively reduces vibration and noise. Subsequently, a lifting pump can be used to pump hot water into the sewage treatment biochemical unit. It is worth expanding that this device is used for but not limited to sewage heating and stirring efficiency-enhancing water heating systems.
