Abstract
The utility model relates to the technical field of pulping equipment, in particular to a bamboo pulp steam heater. The bamboo pulp steam heater comprises an outer housing, wherein a pulp inlet is formed at one end of the casing, a pulp outlet is formed at the other end of the casing, and steam inlet pipes which are arranged in circumferential array are arranged on the casing and longitudinally arranged at intervals along the outer housing. The bamboo pulp steam heater avoids the defects in the prior art, and has the advantages that the bamboo pulp can be uniformly heated, and the manufacturing process is stable.
Description
Technical field
The utility model relates to the pulping equipment technical field, particularly relates to a kind of bamboo pulp steam heater.
Background technology
Pulping technology for paper-making normally will carry out preliminary treatment such as segment, preimpregnation, washing as the waste paper of paper making raw material, wood, cotton, fiber crops, bamboo, grass etc.; Then it is inserted in the pressure vessel to become slightly to starch through HTHP, chemical treatment, be treated to paper making pulps through operations such as screenings again.
Oxygen delignification section O in paper pulp bleaching process, ClO 2 bleaching D, alkaline extraction section E, hydrogen peroxide bleaching section P, hypochlorite bleaching section H need heat slurry.As at oxygen delignification section O, the reaction temperature during oxygen delignification is to influence the key factor that oxygen takes off efficient, and oxygen takes off efficient in order to obtain preferably, and the reaction temperature of oxygen delignification usually need reach 100 ° of C, even higher.
More commonly take off and add low-pressure steam between the standpipe in the pipeline, and realize mixing of steam and slurry by the rotation of middle underflow pump impeller at middle underflow pump and oxygen.This adding mode of low-pressure steam can not well adapt to the fluctuation of production; When needs add more steam or when slurry is less in the pipeline; The affiliation that adds of steam causes pipeline and near the violent vibration of equipment, causes adverse effect to producing normal operation.Therefore the usually compelled sometimes aborning adding that reduces the steam addition or stop low-pressure steam causing slurry temperature not reach desired value therefrom, and the slurry heating is inhomogeneous, makes production technology fluctuation occur.
Especially in the association with pulp bleaching heating process that with the bamboo wood is pulping raw material; Because the peculiar ring structure of bamboo wood; Ring more is prone to form the oar slag in disassociation pulping process; And characteristics such as the fibre length of bamboo pulp is long, fibrocyte is thicker, easy blocking steam steam inlet pipe, to prepare the process result of use undesirable especially being used for bamboo pulp for existing heater.
Summary of the invention
The purpose of the utility model is to avoid weak point of the prior art and a kind of bamboo pulp homogeneous heating that makes is provided, the steam heater of stable processing technique.
The purpose of the utility model realizes through following technical measures:
A kind of bamboo pulp steam heater comprises shell, is provided with the slurry import at an end of shell, and the other end of shell is provided with slurry outlet, and shell is provided with and is the steam steam inlet pipe that circumference array is arranged, and this steam steam inlet pipe is along shell longitudinal separation certain distance.
Wherein, the steam steam inlet pipe is plugged on the shell.
Wherein, the steam steam inlet pipe is welded on the shell.
Wherein, the steam nozzle end of said steam steam inlet pipe is horizontal by acute angle.
Wherein, the shell stage casing is a cylinder tubulose structure.
Wherein, the shell two ends are provided with flange.
The beneficial effect of the utility model: a kind of bamboo pulp steam heater of the utility model; Comprise shell; End at shell is provided with the slurry import; The other end of shell is provided with slurry outlet, and shell is provided with and is the steam steam inlet pipe that circumference array is arranged, and this steam steam inlet pipe is provided with along said shell longitudinal separation.
The steam heater of this structure arrange because the steam steam inlet pipe is circumference array on shell, and along shell longitudinal separation certain distance, the steam steam inlet pipe is evenly distributed on the steam heater, makes the homogeneous heating of slurry, stable processing technique.The steam nozzle end of steam steam inlet pipe is horizontal by acute angle, and towards the slurry flow direction.Make steam steam inlet pipe opening do not meet to slurry come to, avoid slurry flowing pressure influence, and increase and the vapour area, make that the steam steam inlet pipe is difficult for being stopped up by slurry.
Description of drawings
Utilize accompanying drawing that the utility model is further specified, but the content in the accompanying drawing does not constitute any restriction to the utility model.
Fig. 1 is the front view of a kind of bamboo pulp steam heater of the utility model;
Fig. 2 is the left view of a kind of bamboo pulp steam heater of the utility model Fig. 1;
The local enlarged diagram in A place among Fig. 1 of a kind of bamboo pulp steam heater of Fig. 3 the utility model.
In Fig. 1 to Fig. 3, include: 1---shell, 2---slurry import, 3---slurry outlet, 4---steam steam inlet pipe, 5---slurry flow direction, 6---flow of steam direction.
The specific embodiment
In conjunction with following examples the utility model is described further.
Embodiment 1
A kind of bamboo pulp steam heater of the utility model comprises shell 1 shown in Fig. 1-3, shell 1 stage casing is a cylinder tubulose structure.End at shell 1 is provided with slurry import 2; The other end of shell 1 is provided with slurry outlet 3; Shell 1 is provided with and is 4 steam steam inlet pipes 4 that circumference array is arranged, and is rectangular between promptly per two adjacent steam steam inlet pipes 4, and these 4 steam steam inlet pipes 4 are along shell 1 longitudinal separation certain distance.Steam steam inlet pipe 4 is evenly distributed on the steam heater.Admission evenly is convenient to mix with slurry, makes the slurry homogeneous heating, stable processing technique.
Embodiment 2
A kind of bamboo pulp steam heater of the utility model, the difference part is: steam steam inlet pipe 4 is plugged on the shell 1.Steam steam inlet pipe 4 is welded on the shell 1.The steam nozzle end of steam steam inlet pipe 4 is horizontal by acute angle, and towards slurry flow direction 5.Make steam steam inlet pipe 4 openings do not meet to slurry come to, avoid slurry flowing pressure influence, and increase and the vapour area, make steam steam inlet pipe 4 be difficult for being stopped up by slurry, flow of steam direction 6 is consistent with slurry flow direction 5.Shell 1 two ends are provided with flange, are convenient to firmly be installed on the equipment of an operation.
